Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bucket elevator, in particular to a hopper with replaceable back plate. BACKGROUND

[0002] The hopper is an important component of the bucket elevator, which is used to hold materials, scoop up the materials at the bottom and lift them to the top along with the chain, and then overturn the materials into the receiving groove after passing through the top wheel. Since the hopper directly contacts with the materials, the hopper is worn out, especially the back plate is worn out quickly. When the back plate is worn out and cannot be used, other hopper parts are still in good condition and can be used normally. In the conventional hopper, the back plate and other hopper parts are welded together. When the back plate is worn out, the hopper is damaged and cannot be used normally, and the entire hopper needs to be replaced, thereby increasing the replacement cost. SUMMARY

[0003] The utility model discloses a hopper with replaceable back plate, which can replace the back plate alone, reduce the replacement cost and facilitate replacement.

[0004] To achieve the above-mentioned purpose, the utility model provides a hopper with replaceable back plate, which comprises a hopper body, the back side of the hopper body is provided with an opening, the inner sides of the front and rear side plates of the hopper body are both provided with a support body located at the opening, and the support body is provided with a back plate connected through a plurality of bolt pairs I and used for plugging the opening.

[0005] Preferably, the support body is an angle steel.

[0006] Preferably, one side edge body of the support body is welded to the corresponding side plate, and the other side edge body is fixed to the back plate through a plurality of bolt pairs I.

[0007] Preferably, the inner bottom of the hopper body is provided with a flexible body fixed to the hopper body at both ends, and the flexible body is provided with a counterweight.

[0008] Preferably, both ends of the flexible body are fixed to the hopper body through the cooperation of a pressing plate and a plurality of bolt pairs II.

[0009] Preferably, the flexible body comprises a rubber body and a mesh reinforcing body arranged in the rubber body.

[0010] The utility model has the advantages that the back side of the hopper body is provided with an opening, the inner sides of the front and rear side plates of the hopper body are both provided with a support body located at the opening, and the support body is provided with a back plate connected through a plurality of bolt pairs I and used for plugging the opening. When the back plate needs to be replaced due to wear, the back plate can be replaced alone. Compared with the prior art, the back plate can be replaced alone, the replacement cost is reduced, and the replacement is facilitated.

[0011] The features and advantages of the present application will be described in detail with reference to the embodiments combined with the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 is a structure schematic view of a hopper with replaceable back plate of the present application;

[0013] Figure 2 is Figure 1 the cross-sectional view of A-A in Fig.

[0014] In the figure: 1-hopper body, 2-opening, 3-side plate, 4-supporting body, 5-back plate, 6-flexible body, 7-counterweight, 8-bolt pair I, 9-pressing plate, 10-bolt pair II, 61-rubber body, 62-net-shaped reinforcing body. DETAILED DESCRIPTION

[0015] Referring to Figure 1 , Figure 2 , the present application is a hopper with replaceable back plate, which comprises a hopper body 1, the back side of the hopper body 1 is provided with an opening 2, the inner side of the front and rear side plates 3 of the hopper body 1 is provided with a supporting body 4 at the opening 2, and the supporting body 4 is provided with a back plate 5 which is detachably connected through a plurality of bolt pairs I 8 for plugging the opening 2.

[0016] The supporting body 4 is an angle steel.

[0017] One side edge body of the supporting body 4 is welded to the corresponding side plate 3, and the other side edge body is fixedly connected to the back plate 5 through a plurality of bolt pairs I 8.

[0018] The inner bottom of the hopper body 1 is provided with a flexible body 6 which is fixedly connected to the hopper body 1 at both ends, and the flexible body 6 is provided with a counterweight 7.

[0019] Both ends of the flexible body 6 are fixedly connected to the hopper body 1 through the cooperation of the pressing plate 9 and a plurality of bolt pairs II 10.

[0020] The flexible body 6 comprises a rubber body 61 and a net-shaped reinforcing body 62 arranged in the rubber body 61.

[0021] The working process of the present application is as follows:

[0022] In the working process of the present application, when the back plate 5 needs to be replaced due to wear, the bolt pair I 8 is first disassembled, then the back plate 5 to be replaced is disassembled, and then the new back plate 5 is fixedly installed on the supporting body 4 through the bolt pair I 8.

[0023] When the hopper of the bucket elevator operates to unload at the head, the flexible body 6 moves to the direction of the hopper mouth under the weight of the counterweight 7, so that the flexible body 6 deforms rapidly, and the material falls off instantaneously.

[0024] The above examples are used to illustrate the present application, but not to limit the present application, and any simple transformation of the present application belongs to the protection scope of the present application.
