Detailed Description

Referring to fig. 3-6, reflecting a specific structure of the present invention, a rigid cylinder 50 is disposed below a hopper body 10 of a collecting hopper of a concrete mixing plant, and a lower end opening of the hopper body 10 is connected with an upper end opening of the cylinder 50; a sealing door assembly is arranged at the lower port of the cylinder body 50; the sealing door assembly comprises a bottom plate 40 arranged corresponding to the lower port of the cylinder 50, the driving side of the bottom plate 40 is connected with a driving unit, namely the air cylinder 20, one end of the air cylinder 20 is hinged with the frame, the other end of the air cylinder 20 is hinged with the driving side of the bottom plate 40, and the air cylinder 20 can flexibly drive the bottom plate 40 to swing back and forth through stretching. Likewise, a cylinder or an electric push rod can also perform the same work.

The two adjacent sides of the bottom plate 40 and the driving side are fixedly connected with the side plates 30, and the top ends of the side plates 30 are hinged on the rack. The bottom plate 40 is reciprocally swung along a hinge point at the top end of the side plate 30 by the cylinder 20, thereby switching between two states of a/B:

State A As shown in FIG. 3, the bottom plate 40 swings to the left, closing the lower port of the cylinder 50 for collecting material;

The state B is shown in fig. 6, in which the bottom plate 40 swings to the right, and the lower port of the drum 50 is opened for discharging. When the collecting hopper discharges, the bottom plate 40 swings to the driving side, so that the discharging of the concrete at the lower port of the cylinder 50 cannot be blocked, and the discharging can be performed smoothly.

In order to optimize the sealing effect, the driving side and two sides adjacent to the driving side of the bottom plate 40 are provided with enclosing plates 60 fixedly connected to the top of the bottom plate 40, the opposite side of the driving side is provided with a sealing plate 70 fixedly connected to the cylinder 50, the top of the sealing plate 70 is welded to the outer wall of the cylinder 50, and the bottom of the sealing plate 70 extends downwards to be engaged with the top of the bottom plate 40.

In the state A, the sealing plate 70 is connected with the enclosing plate 60 to form a closed-loop sealing belt arranged around the lower port of the cylinder body 50, so that the leakage of materials is effectively avoided; in the closed-loop sealing strip, sealing rubber strips are arranged between the enclosing plate 60 and the sealing plate 70 and the lower port of the cylinder body 50.

In this example, the lower end of the cylinder 50 is an arc-shaped end, the arc-shaped peak of the arc-shaped end protrudes downwards, the arc-shaped peak is located on the central axis of the cylinder 50, and two sides of the arc are symmetrically distributed along the central axis. The bottom plate 40 is an arc bottom plate corresponding to the arc port. The cambered surface of the bottom plate 40 can be well connected with the cambered end of the barrel 50, and no material overflows exist and no interference exists.

In the state a, there is a deviation Δ L between the central axis of the bottom plate 40 and the central axis of the arc-shaped port, and the central axis of the bottom plate 40 is closer to the driving side of the bottom plate 40. Therefore, in the rotation process of switching the state of the bottom plate 40 from the A state to the B state, the bottom plate 40 and the lower port of the cylinder 50 cannot be locked due to the mortar residue on the bottom plate 40.

Wear-resistant lining plates are arranged inside the cylinder body 50 and on the upper surface of the bottom plate 40. The wear resistance of the base plate 40 and the cylinder 50 is improved

The above-mentioned implementation is only for clearly illustrating the technical solutions of the present invention, and is not to be construed as limiting the present invention in any way. The present invention has many known alternatives and modifications in the art, which fall within the scope of the present invention without departing from the spirit of the present invention.
