Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant hoppers, in particular to a wear-resistant hopper with a replaceable hopper mouth. Background Art

[0002] Bucket elevators are mainly composed of a bucket, chain, sprocket, housing, and power system. The bucket is fixed to the chain with bolts, and the power system drives the chain and bucket through the sprocket to move, so as to transport materials from the bottom of the elevator to the top. When the bucket is filled with material and unloading at the bottom of the elevator and the top, the bucket mouth and the front plate of the bucket body will rub against the material, causing the bucket to wear and break, seriously affecting production efficiency. Repairing the bucket not only takes a long time, but also requires additional shipping costs, labor costs, etc. The maintenance cost is too high and the effect is poor. Therefore, users often have to scrap the bucket with worn bucket mouth and bucket body front plate but intact other parts and replace it with a new one, which results in a huge waste of resources.

[0003] Some existing hoppers are made of ordinary steel plates. The hopper mouth frequently rubs against the material during filling and unloading, and the hopper mouth is easily damaged, affecting the output of the elevator and the stability of the equipment operation, and shortening the service life of the hopper. The hopper with a worn hopper mouth requires a long time to repair and the cost is relatively high. Direct replacement will cause a huge waste of resources and increase the company's equipment maintenance costs. Worn hoppers will lead to uneven material distribution, aggravate the vibration fatigue wear of the transmission equipment, and affect the service life of the elevator sprocket and reducer. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a wear-resistant hopper with a replaceable hopper mouth.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A wear-resistant hopper with a replaceable bucket mouth comprises a bucket body, a bucket body front plate is provided on one side of the bucket body, a movable bucket mouth is slidably connected to the side of the bucket body close to the bucket body front plate, a plurality of connecting bolts are installed on the movable bucket mouth close to the side of the bucket body front plate, and the plurality of connecting bolts and the bucket body front plate are arranged in cooperation with each other, bucket body outer guard plates are fixedly connected on both sides, hopper side plates are provided on both sides of the bucket body, a material-blocking and wear-resistant area is provided inside the bucket body front plate, and a plurality of exhaust holes are opened inside the bucket body. By setting the movable bucket mouth, it can be ensured that the material can be evenly distributed.

[0007] The beneficial effects of the utility model are:

[0008] 1. External guard plates are welded on both sides of the bucket body to improve the strength of the bucket and prevent deformation without affecting the disassembly and assembly of the movable bucket mouth;

[0009] 2. The movable hopper mouth is made of wear-resistant material and the connecting bolts are high-strength bolts to improve system reliability and extend the service life of the hopper;

[0010] 3. Enlarge the side plates of the hopper so that they protrude from the hopper body. This reduces the contact area with the material, breaks the surface tension of the material, reduces the friction between the material and the movable hopper mouth and the front plate of the hopper body, and extends the service life of the hopper.

[0011] 4. Welding a material-resistant wear-resistant area on the front loading plate of the bucket body can reduce the erosion and wear of the material on the bucket mouth and the front loading plate. At the same time, it can form a protective connecting bolt for the slow-flowing material layer to avoid direct erosion of the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] Reference Figure 1-Figure 3A wear-resistant hopper with a replaceable bucket mouth includes a bucket body 8, a bucket front plate 5 is provided on one side of the bucket body 8, and a movable bucket mouth 2 is slidably connected to the side of the bucket body front plate 5 near the bucket body front plate 5. A plurality of connecting bolts 3 are installed on the side of the movable bucket mouth 2 near the bucket body front plate 5, and the plurality of connecting bolts 3 are matched with the bucket body front plate 5. Bucket outer guard plates 1 are fixedly connected on both sides of the bucket body 8, and hopper side plates 4 are provided on both sides of the bucket body 8. A material-blocking wear-resistant area 6 is provided inside the bucket body front plate 5, and a plurality of exhaust holes 7 are opened inside the bucket body 8. Through the setting of the movable bucket mouth 2, it can be ensured that the material can be evenly distributed.

[0019] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: the present invention is designed to improve the shortcomings of the bucket mouth and the front plate of the bucket body of the elevator hopper being easily worn out during the material collection and unloading process, resulting in a short service life, a long time and high cost for replacing the entire hopper, etc., and includes a bucket outer guard plate 1, a movable bucket mouth 2, connecting bolts 3, a hopper side plate 4, a bucket body front plate 5, a material blocking wear-resistant area 6, an exhaust hole 7, and a bucket body 8. The utility model is characterized in that the bucket outer guard plate 1 is fixed to both sides of the bucket body 8 by welding to reinforce the bucket body and prevent deformation; the movable bucket mouth 2 is fixed to the bucket body front plate 5 by connecting bolts 3 and can be flexibly replaced; the bucket body front plate 5 is welded with steel strips to form a material blocking wear-resistant area 6, which can effectively reduce the wear of the bucket body front plate 5 by the material and extend the service life of the hopper; the hopper side plate 4 is an integral part of the bucket body 8, but has a larger cross-section than the bucket body 8, which can effectively prevent foreign objects from colliding with the hopper and prevent the bucket body from being deformed by impact. The easily worn hopper mouth of the hopper is made of wear-resistant plate made of NM500 material, which can effectively resist material wear, and the bolted connection structure can improve maintenance efficiency and avoid the cost waste caused by overall replacement. The material-blocking wear-resistant area 6 can reduce the erosion of the material on the front plate 4 of the hopper body, and at the same time protect the connecting bolts 3 to prevent the bolts from wearing and falling off.
