Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

The transfer point chute device is transition equipment for transporting materials by two conveyors, and has the functions of enabling bulk (particle or block) materials to be smooth, small in impact and less in dust emission to be transferred from one layer of conveyor belt to the other layer of conveyor belt.

Referring to fig. 1, there is shown an example of the composition of the chute apparatus for the transfer point of the belt conveyor given in this example.

As can be seen, the chute device 100 for the transfer point of the belt conveyor is mainly formed by the cooperation of an upper material receiving control assembly 110, a lower material receiving control assembly 120, a multi-stage material storage tank 130 and a discharging adjustment assembly 140.

The upper receiving control assembly 110 and the lower receiving control assembly 120 are disposed opposite to each other, and an adjustable transfer passage 150 is formed between the feeding end of the multi-stage storage chute 130 and the terminal end of the first transporting belt 200, so as to transfer the materials of the first transporting belt 200 to the multi-stage storage chute 130. The distribution position of the upper receiving control assembly 110 and the lower receiving control assembly 120 relative to the multi-stage storage tanks is adjustable, so that the relative position relationship between the outlet of the transfer channel 150 and the multi-stage storage tanks 130 is adjusted by adjusting the position of the upper receiving control assembly 110 and/or the lower receiving control assembly 120 relative to the multi-stage storage tanks, and then the receiving adjustment and control are realized.

The multistage storage chute 130 in the chute device 100 stores and buffers materials temporarily through a multistage storage chute structure. The multi-stage storage chute 130 can cooperate with the adjustable transfer channel 150 to selectively buffer the material according to the energy of the material.

The discharge adjustment assembly 140 of the chute apparatus 100 is disposed between the discharge end of the multi-stage storage chute 130 and the second conveyor belt 300, and is configured to adjust the direction and speed of the material exiting from the discharge end of the multi-stage storage chute 130.

For example, in the chute device 100, the upper material receiving control assembly 110 is mainly formed by matching the upper material receiving cylinder 111 and the upper material receiving plate 112, and the lower material receiving control assembly 120 is mainly formed by matching the lower material receiving cylinder 121 and the lower material receiving plate 122.

Accordingly, the upper receiving plate 112 is disposed between the upper side of the terminal end of the first transporting belt 200 and the upper side of the feeding end of the multi-stage storage chute 130, and the lower end of the upper receiving plate 112 preferably extends into the feeding end of the multi-stage storage chute 130 as the upper sidewall of the adjustable transfer passage 150. The upper end of the upper material receiving plate 112 (i.e., the end away from the multi-stage storage chute 130) is hinged, so that the lower end of the upper material receiving plate 112 can swing relative to the multi-stage storage chute 130.

The specific structure of the upper receiving plate 112 may be determined according to actual requirements, and for example, the upper receiving plate is a flat plate structure, but is not limited thereto.

The upper material receiving cylinder 111 is used as an upper material receiving driving assembly for driving the upper material receiving plate 112 to swing around the hinge point. The upper material receiving cylinder 111 can be replaced by other driving components as required, as long as the upper material receiving plate 112 can be effectively driven.

In a specific setting, the fixed end of the upper material receiving cylinder 111 is connected, and in the illustrated embodiment, the upper material receiving cylinder 111 and the upper material receiving plate 112 are fixed on the same plane by means of hinges, but the invention is not limited thereto. The action end of the upper material receiving cylinder 111 is directly hinged with the plate body of the upper material receiving plate 112, and the specific connecting position can be determined according to actual requirements. The upper material receiving oil cylinder 111 arranged in this way can effectively drive the upper material receiving plate 112 to rotate (namely swing) around the hinge point of the upper material receiving plate.

In cooperation, the lower material receiving plate 122 is distributed between the lower side of the terminal end of the first transporting belt 200 and the lower side of the feeding end of the multi-stage material storage tank 130 relative to the upper material receiving plate 112, and the lower end of the lower material receiving plate 122 preferably extends into the feeding end of the multi-stage material storage tank 130 to serve as the lower side wall of the adjustable transfer passage 150. The upper end of the lower material receiving plate 122 (i.e., the end away from the multi-stage storage chute 130) is hinged, so that the lower end of the lower material receiving plate 122 can swing relative to the multi-stage storage chute 130.

The specific structure of the lower material receiving plate 122 may be determined according to actual requirements, for example, the lower material receiving plate 122 in this embodiment is a flat plate structure, and the lower end of the lower material receiving plate is tilted upward at a certain angle relative to the main body of the lower material receiving plate 122, so that a certain buffering and direction adjustment can be formed when the material guided and moved by the lower material receiving plate 122 enters the multi-stage material storage tank 130.

The lower material receiving cylinder 121 is used as a lower material receiving driving assembly to be connected with the lower material receiving plate 122 in a driving manner so as to drive the lower material receiving plate 122 to swing around a hinge point. The lower material receiving cylinder 121 can be replaced by other driving assemblies as required, as long as the lower material receiving plate 122 can be effectively driven.

In the specific arrangement, the fixed end of the lower material receiving cylinder 121 is connected, and in the illustrated embodiment, the lower material receiving cylinder 121 and the lower material receiving plate 122 are fixed on the same plane by means of hinges, but not limited thereto. The action end of the lower material receiving oil cylinder 121 is directly hinged with the plate body of the lower material receiving plate 122, and the specific connecting position can be determined according to actual requirements. The lower material receiving oil cylinder 121 arranged from above can effectively drive the lower material receiving plate 122 to rotate (namely swing) around the hinge point of the lower material receiving plate.

Further, multistage stock chest 130 among this chute device 100 adopts the two-stage stock chest structure, including two-stage storage cell body 131 and discharging channel 132, two-stage storage cell body 131 has higher level stock chest 131a and lower level stock chest 131b that are the step form and distribute, the higher level stock chest 131a and lower level stock chest 131b that are the step form and distribute simultaneously set up with feed inlet 133 on multistage stock chest 130 relatively, so two-stage chute structure, under the prerequisite that does not obviously increase the processing technology degree of difficulty, effectively increase the progression of buffering material impact energy, thereby can effectively improve whole chute device 100's reliability.

Meanwhile, the upper end of the two-stage material storage groove body 131 is provided with a material inlet 133, and is matched with a material outlet of an adjustable transfer channel 150 formed by matching the upper material receiving plate 112 and the lower material receiving plate 122. Furthermore, the lower end of the two-stage storage tank body 131 is provided with a discharge channel 132 for matching with the second transportation adhesive tape 300. The discharge channel 132 here has a discharge direction opposite to the feed direction of the adjustable transfer channel 150, in order to buffer the material being transferred over time.

In addition, a corresponding guide structure can be arranged at the port of the discharging channel 132 according to the requirement, and the specific structural form can be determined according to the actual requirement.

Further, the discharging adjustment assembly 140 in the chute device 100 is mainly formed by matching an angle adjusting cylinder 141 and an angle adjusting plate 142.

The angle-adjusting plate 142 is disposed at an inclined angle at the lower side of the port of the discharging channel 132, and is engaged with the second conveyor belt 300 as an extension of the lower side of the port of the discharging channel 132. The upper end of the angle-adjusting plate 142 (i.e., the end away from the second conveyor belt 300) is hinged such that the lower end of the angle-adjusting plate 142 can swing with respect to the second conveyor belt 300.

The specific structure of the angle adjusting plate 142 can be determined according to actual requirements, for example, the angle adjusting plate 142 in this embodiment is a flat plate structure, and the lower end of the angle adjusting plate is tilted upward at a certain angle relative to the main body of the angle adjusting plate 142, so that certain buffering and direction adjustment can be formed when the material guided and moved by the angle adjusting plate 142 enters the second conveyor belt 300.

The angle adjusting cylinder 141 is used as an angle adjusting driving component for driving the connecting angle adjusting plate 142 to drive the angle adjusting plate 142 to swing around the hinge point. The recliner cylinder 141 may be replaced by another driving assembly as required as long as the recliner plate 142 can be driven effectively.

In a specific setting, the fixed end of the reclining cylinder 141 is connected, and in the illustrated embodiment, the reclining cylinder 141 and the reclining plate 142 are respectively fixed on the same plane in a hinged manner, but not limited thereto. The action end of the angle adjusting oil cylinder 141 is directly hinged with the plate body of the angle adjusting plate 142, and the specific connecting position can be determined according to the actual requirement. The thus provided recliner cylinder 141 is effective to drive the recliner plate 142 to rotate about its hinge point (i.e., to swing with respect to the second conveyor belt 300).

The chute device 100 for the transfer point of the belt conveyor can act through the upper material receiving oil cylinder 111 or/and the lower material receiving oil cylinder 121, so that the angle of the corresponding material receiving plate can be effectively adjusted, and the running track of the material can be further adjusted and controlled; meanwhile, the two-stage material storage tank 130 is matched, so that the energy of the materials can be selectively buffered by selecting through the adjusting device (namely the material receiving oil cylinder and the material receiving plate) according to the material speed. Specifically, if the feeding speed is high, the lower material receiving cylinder 121 is controlled to extend, and the upper material receiving cylinder 111 is controlled to contract, so that the lower material receiving plate 122 is lifted by a certain angle; therefore, the material track falls on the upper material storage tank 131a, and then slides from the upper material storage tank 131a to the lower material storage tank 131b, so that two-stage speed reduction and two-stage buffering are realized. If the feeding speed is slow, the lower material receiving cylinder 121 is controlled to contract, and the upper material receiving cylinder 111 is controlled to extend, so that the lower material receiving plate 122 rotates downwards for a certain angle; the material trajectory directly falls into the lower storage chute 131b to perform first-level deceleration and first-level buffering (as shown in fig. 2).

Furthermore, the chute device 100 can adjust the speed direction of the material at the discharge port through the discharge adjusting assembly (as shown in fig. 3), and has the functions of effectively utilizing the energy of the material, reducing the impact on the downward conveying adhesive tape and preventing blockage.

By way of example, the following describes the application of the chute apparatus 100 for a transfer point of a belt conveyor.

Referring to fig. 1 and 3, in actual operation of the chute device 100 for the transfer point of the belt conveyor, the whole chute device 100 is arranged between an upper conveyor belt (i.e., a first conveyor belt) 200 positioned on an upper layer and a lower conveyor belt (i.e., a second conveyor belt) 300 positioned on a lower layer; the chute devices 100 constitute respective buffer transfer passages (as described above) between the upper conveyor belt (i.e., the first conveyor belt) 200 and the lower conveyor belt (i.e., the second conveyor belt) 300.

Thus, the material 400 conveyed by the upper conveying belt 200 converges in one of the upper stage storage tank and the lower stage storage tank of the two-stage storage tanks under the combined action of the upper material receiving plate and the lower material receiving plate; the upper material receiving plate and the lower material receiving plate are adjustable in angle under the action of the upper material receiving oil cylinder and the lower material receiving oil cylinder respectively, and therefore materials can be controlled to converge on the stage number of the two-stage storage tanks. If the material speed is fast and the kinetic energy is large, the upper and lower material receiving plates should be adjusted to preliminarily converge the material in the upper storage chute, buffer the material energy and reduce the impact (as shown in fig. 2).

The inclination angle of the angle adjusting plate is adjusted by an angle adjusting oil cylinder at the discharge port of the chute so as to keep the consistency of the speed direction of the material at the outlet and the running direction of the lower conveying belt; in addition, the angle adjusting plate is adjusted through the angle adjusting oil cylinder, the anti-blocking function can be further achieved, when the discharging flow is larger than the conveying flow of the conveying belt, the discharging hole is blocked, the angle adjusting plate can be adjusted through the angle adjusting oil cylinder to change the discharging falling angle, the material receiving sectional area of the conveying belt is changed, the discharging flow can be reduced (or increased), and the blocking condition is buffered.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
