Technical Field

The invention belongs to the technical field of conveying equipment, and particularly relates to a bottom cleaning and plate turning device of an unpowered automatic bucket elevator.

Background

In prior art, the hopper lifting machine is in the operation in-process, hardly avoids falling the material phenomenon because of the feed with the in-process of unloading appears, often because fall the material serious, produces the bottom and gathers materials too much, influences hopper lifting machine hopper wearing and tearing, leads to causing the part to damage even.

In order to solve the problem, a mode of additionally arranging a short belt conveyor and a scraper conveyor at the bottom of a bucket elevator to remove bottom blanking exists at present, and although the function of removing bottom materials can be achieved, a lot of problems can be caused at the same time.

1. The problem of material falling prevention is considered during design of the bucket elevator, and material falling can not be completely avoided, so that the material falling amount is not very serious and is very small. The mode of removing the bottom blanking by additionally arranging the short belt conveyor and the scraper conveyor at the bottom of the bucket elevator needs to be operated for a long time if the belt conveyor and the scraper conveyor work together with the bucket elevator, so that not only is efficiency not high, but also energy is wasted.

2. Use belt feeder and scrape trigger clearance bed charge, because carry the material export remain throughout with external opening, the inside dust of machine is carried to the fill reveals easily, influences operational environment, so adopt this mode very much, need add sealed cowling and dust arrester installation simultaneously, the structure is complicated, with high costs.

3. The bottom of the bucket elevator is additionally provided with the belt conveyor or the scraper conveyor, maintenance and overhaul equipment is added, maintenance cost is increased, and meanwhile, due to the fact that the bottoms of a plurality of bucket elevators are arranged in a pit, inconvenience and difficulty are increased for monitoring, maintaining and overhauling the equipment.

Disclosure of Invention

The invention aims to provide the bottom cleaning and plate turning device of the unpowered automatic bucket elevator, which has the advantages of no need of power, no need of monitoring, simple maintenance, simple structure and low cost, and can automatically clean the inside bottom materials without manual work.

The technical solution of the invention is as follows: the bottom cleaning turning plate device of the unpowered automatic bucket elevator is characterized by comprising a material receiving cross-shaped turning plate arranged at the lower part of a rotating device at the lower part of the bucket elevator, and a rotating shaft arranged in the middle of the turning plate; the end of the horizontal turning plate of the cross turning plate is in small-gap contact with the side wall of the bucket elevator; a material receiving plate, a left discharge opening and a right discharge opening are arranged on the side wall of the bucket elevator corresponding to the lower side part of the cross-shaped turning plate.

In the above scheme, the method further comprises:

the two sides of the vertical plate at the upper part of the cross turning plate are welded with material-meeting inclined plates.

And the lower part of the lower turning plate of the cross turning plate is welded with counterweight round steel which is beneficial to the reset of the cross turning plate.

The invention has the advantages that: 1. simple structure, easy manufacture, installation, maintenance and overhaul and low cost. 2. The device adopts the unpowered design, no running cost. 3. The device adopts the automatic deashing that overturns, need not long-time control, saves the cost of labor. 4. The device has the advantages of no material storage at the bottom of the bucket elevator and high protectiveness. 5. When the device is used, after the cross-shaped turning plate is balanced, the effect of dust leakage in the sealing machine can be realized, and meanwhile, the canvas dust-blocking curtain is additionally arranged at the discharge opening, so that the dust leakage can be greatly reduced, and the device has a simple structure and an ideal effect.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Detailed Description

Referring to fig. 1-3, the part names are as follows: the cross board 1 that turns over, axis of rotation 2, meet material swash plate 3, the machine pan feeding mouth 4 is carried to the fill, and the machine lateral wall 5 is carried to the fill, and counter weight round steel 6 connects flitch 7, left discharge opening 8, right discharge opening 9, the material 10 is fallen to the pan feeding mouth, and the discharge opening falls material 11.

Referring to fig. 1, the bottom cleaning turning plate device of the unpowered automatic bucket elevator is characterized in that a material receiving cross-shaped turning plate 1 is arranged at the lower part of a rotating device at the lower part of the bucket elevator, the cross-shaped turning plate 1 is in a cross shape, a rotating shaft 2 is arranged in the middle of the cross-shaped turning plate 1, and rolling bearing seats are arranged at two ends of the rotating shaft 2, so that the cross-shaped turning plate 1 can axially rotate. The material-meeting inclined plates 3 are welded on two sides of the vertical plate on the upper portion of the cross turning plate 1, and the effect of preventing materials from accumulating towards the center of the rotating shaft 2 and influencing turning is achieved. The end of the horizontal turning plate of the cross turning plate is in small-gap contact with the side wall 5 of the bucket elevator as much as possible, and the cross turning plate 1 plays a role in sealing dust overflow when balanced. The lower part of the lower turning plate of the cross turning plate is welded with a counterweight round steel bar 6 which is used for welding the lower part of the lower turning plate of the cross turning plate 1After unloading, the cross turning plate 1 is reset under the action of gravity. The cross board lower side portion that turns over designs and connects flitch 7 and left discharge opening 8, right discharge opening 9, and the effect is that the restriction cross board 1 angle that turns over and connect the effect of material unloading, and the discharge opening is equipped with canvas dust blocking curtain (the picture is slightly) simultaneously, and the dust is excessive when reducible unloading. The cross turning plate 1 is made of wear-resistant material (61 Mn), and the rotating shaft 2 is made of 45 material^#。

The working principle is as follows: when 4 regions of machine pan feeding mouth take place to fall to expect, the material falls into the left side region that the cross turned over board 1, along with the material accumulation weight be greater than the long-pending material weight in right side or when being greater than 6 weights of bottom counter weight round steel, the cross turned over board 1 can turn to one side left to with the material through the left discharge opening 8 of machine lower part is carried to the bucket and discharges out (the cross turns over board 1 slope after can connect flitch 7 to carry on spacingly through the lower part). When the hopper lifter discharge opening area is subjected to material dropping, the principle is the same as that of the left side.

The foregoing description is only exemplary of the invention and is not intended to limit the spirit of the invention.
