Abstract
Description
Technical Field
[0001] This utility model relates to the field of material storage equipment technology, specifically to a wear-resistant steel sand hopper. Background Technology
[0002] In the industrial sector, steel shot is a common metallic material, widely used in shot blasting and casting of equipment.
[0003] Because the amount of steel shot used in the foundry industry is large, the steel shot is usually temporarily stored in the box. Due to the characteristics of the steel shot itself, frequent feeding and discharging cause the steel shot to collide directly with the side wall of the box, which will lead to severe wear of the box and affect its service life. In particular, when the steel shot is flowing, the wear of the steel plates on the side walls and the two sides of the bottom conical discharge port will be accelerated. Even if the thickness of the steel plate is increased, the effect is still not ideal. Utility Model Content
[0004] To overcome the above-mentioned defects, the purpose of this utility model is to provide a wear-resistant steel sand hopper, which reduces the friction between the steel sand and the inner wall of the hopper body by setting a protective device inside the hopper body, thereby improving the service life of the equipment.
[0005] To achieve the above objectives, this utility model provides a wear-resistant steel sand hopper, including a hopper body, the hopper body being provided with a protective device; the protective device includes a connecting plate and a support plate, the connecting plate being fixedly connected to the inner wall of the hopper, and a plurality of support plates being detachably connected to the connecting plate; steel sand is filled between two adjacent support plates, and the support plates are perpendicular to the connecting plate.
[0006] Preferably, the connecting plate is provided with a limiting hole, and one end of the support plate is provided with a connecting rod adapted to the limiting hole, the connecting rod being inserted into the limiting hole.
[0007] Preferably, the bottom of the support plate is provided with a reinforcing rib plate, one end of which is fixedly connected to the support plate and the other end of which abuts against the connecting plate.
[0008] Preferably, the support plate is trapezoidal, and the width of one end near the connecting plate is greater than the width of the other end.
[0009] Preferably, the support plate is trapezoidal, and the width of one end near the connecting plate is greater than the width of the other end.
[0010] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:
[0011] 1. Because a connecting plate and a support plate are placed inside the hopper body, and the support plate is perpendicular to the connecting plate, a certain amount of steel shot will be filled in the cavity of the adjacent support plate. Therefore, the steel shot close to the connecting plate will hardly collide with the connecting plate, and there will be almost no rapid friction. When the steel shot slides, its collision and friction come from the steel shot itself. Therefore, it can improve the service life of the hopper body and avoid the phenomenon of "leaking material" to a certain extent.
[0012] 2. The connecting plate is composed of multiple connecting plate units. The connecting plate units are small in size, making assembly and movement more convenient. It is also easier to set limit holes on the connecting plate. After the support plate and connecting rod are installed, they are fixed inside the hopper body. It can be installed as a whole or in parts. Therefore, replacement and disassembly are more convenient, and construction is more convenient. Compared with replacing the entire hopper body, it can significantly reduce maintenance costs. In actual use, the parts that are obviously easy to wear through can be reinforced according to the actual usage conditions.
[0013] 3. The protective device and the hopper body are disassembled and installed separately, and are processed and molded separately. It is suitable for upgrading and modifying existing hopper bodies at a low cost. In particular, the addition of the protective device can solve the leakage problem caused by corrosion in some hoppers, making it more practical. The installation is relatively simple and has almost no impact on material storage and discharge. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0023] See Figure 1-Figure 4 This utility model provides a wear-resistant steel shot hopper, comprising a hopper body 1, with a protective device 2 inside the hopper body 1. The protective device 2 includes a connecting plate 21 and a support plate 22. The connecting plate 21 is fixedly connected to the inner wall of the hopper, and several support plates 22 are detachably connected to the connecting plate 21. Steel shot 3 is filled between adjacent support plates 22, and the support plates 22 are perpendicular to the connecting plate 21. The hopper body 1 and the protective device 2 are processed independently. Generally, after the protective device 2 is processed, it is fixed to the inner wall of the hopper body 1 by means of fastening bolts, welding, etc. Figure 1 As shown, after installation, steel shot 3 is placed in the central cavity of the hopper body 1. The steel shot 3 also fills the space between adjacent support plates 22. With multiple support plates 22 supporting the steel shot 3, during unloading, because the support plates 22 are almost perpendicular to the connecting plate 21, the steel shot 3 near the inner wall of the hopper body 1 hardly moves due to the influence of the support plates 22, thus forming a "protective shield." Compared to... Figure 4 With the addition of protective device 2, the movement direction of the steel shot 3 is adjusted so that there is almost no direct impact, which can reduce the wear on the inner wall of the hopper.
[0024] The connecting plate 21 of this utility model is provided with a limiting hole 211, and one end of the support plate 22 is provided with a connecting rod 221 that is adapted to the limiting hole 211. The connecting rod 221 is inserted into the limiting hole 211. A reinforcing rib plate 222 is welded to the bottom of the support plate 22, and a connecting rod 221 is welded to one side. The connecting plate 21 is provided with a corresponding limiting hole 211. During installation, the connecting rod 221 is inserted into the corresponding limiting hole 211, and the side wall of the support plate 22 abuts against the inner wall of the hopper body 1. With the reinforcement rib plate 222 for reinforcement, the support plate 22 is fixed.
[0025] The support plate 22 of this invention is trapezoidal, and the width of one end near the connecting plate 21 is greater than the width of the other end. According to the axiom of mechanics, the greater the extension distance, the easier it is to bend and deform. The support plate 22 is generally made of iron. In order to reduce its deformation, the width of the extension end of the support plate 22 is slightly smaller than the width of the other side. After installation, the force will be more balanced and it will not be easy to deform.
[0026] The connecting plate 21 of this utility model is composed of several connecting plate 21 units spliced together. The connecting plate 21 is used to support the support plate 22, and has a certain thickness and rigidity. During installation, it can be cut according to the actual shape of the hopper body 1 before transportation, which makes construction more convenient. It is especially suitable for some hopper bodies 1 with very large volume.
[0027] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
