[0002] The most commonly used hopper structures are cylindrical hoppers with spiral grooves and conical hoppers. As auxiliary equipment in the conveying system, it plays the role of connecting and coordinating the crane and belt conveyor system.
[0003] Polyurethane material as the material of the hopper has the advantages of wear resistance, corrosion resistance, aging resistance and good cushioning and shock absorption performance. However, in high-latitude environments, the temperature can be as low as -40°C, causing the polyurethane hopper to shrink and deform during use, affecting the impact resistance of the polyurethane hopper. Utility Model Content
[0004] In order to reduce the impact of low temperature environment on the impact resistance of the polyurethane hopper, the present application provides a conical polyurethane hopper.
[0005] The conical polyurethane hopper provided in this application adopts the following technical solution:
[0006] A conical polyurethane hopper comprises a conical cylinder body, wherein the conical cylinder body comprises an inner wall layer and an outer wall layer, a screen is provided between the inner wall layer and the outer wall layer, and the screen is a conical cylinder structure.
[0007] By adopting the above technical solution, the screen is arranged between the inner wall layer and the outer wall layer of the cone cylinder body, so that the screen serves as the skeleton structure of the cone cylinder body, the structure of the cone cylinder body is strengthened, and the polyurethane hopper is not prone to shrinkage and deformation in a low temperature environment, which is beneficial to ensuring the rigidity and impact resistance of the polyurethane hopper.
[0008] Optionally, the port plane of the small end and the port plane of the large end of the cone body are relatively inclined.
[0009] By adopting the above technical solution, the material passing through the hopper is discharged at an angle, which can improve the discharge efficiency of the hopper and reduce the accumulation of material at the lower end of the hopper, which affects the material unloading efficiency.
[0010] Optionally, the outer wall layer is provided with a first flange, and the inner wall layer is provided with a second flange, the second flange is farther away from the small end of the cone body relative to the first flange, and a plurality of lifting components are connected between the first flange and the second flange.
[0011] By adopting this technical solution, the first flange reinforces the large end of the outer wall layer, and the second flange reinforces the large end of the inner wall layer, thereby enhancing the structural stability of the cone body. The first and second flanges are connected by a lifting member, forming a relatively stable overall structure with the first and second flanges and the lifting member. This allows the hopper to maintain a stable structural form when hoisted and used, reducing deformation during use.
[0012] Optionally, the screen is bonded to the inner wall layer and the outer wall layer respectively by adhesive.
[0013] By adopting the above technical solution, the screen is bonded to the inner wall layer and the outer wall layer through the adhesive, so that the inner wall layer and the outer wall layer form a stable whole.
[0014] Optionally, the inner wall layer and the outer wall layer are connected as one body, and the screen is embedded in the inner wall of the inner wall layer.
[0015] By adopting the above technical solution, when manufacturing the hopper, the outer wall layer is first injection molded, and then the screen is placed on the inner side of the outer wall layer. Then, the inner wall layer is injection molded on the basis of the outer wall layer, so that the screen is injection molded and wrapped in the inner wall layer. At the same time, the outer wall layer and the inner wall layer are injection molded into a whole, which is beneficial to ensure the integrity of the cone body.
[0016] Optionally, a plurality of push rods are provided at the large end of the screen, and the push rods are wrapped in the inner wall layer, and one end of the push rod away from the screen is kept flush with the surface of the second flange away from the first flange.
[0017] By adopting the above technical solution, after the outer wall layer of the cone body is injection-molded, when the inner wall layer is injection-molded, the inner wall of the mold used to form the inner wall layer is abutted against the top rod, so that the screen is as close to the inner surface of the outer wall layer as possible, which is conducive to controlling the position accuracy of the screen on the inner side of the outer wall layer.
[0018] Optionally, the screen is a wire mesh, and the top rod is a steel wire end of the wire mesh.
[0019] By adopting the above technical solution, the wire ends of the wire mesh are used as the top rods, and there is no need to add additional components corresponding to the top rods, which is more convenient.
[0020] Optionally, the push rod is inclined relative to the generatrix direction of the screen.
[0021] By adopting the above technical solution, when the busbar directions of the push rod and the screen are relatively inclined, when the top end of the push rod is uneven, the push rod is easier to deform to avoid the mold used to form the inner wall layer.
[0022] Optionally, the screen is provided with an inwardly arched deformation band, and the deformation band is arranged along the entire length of the busbar direction of the screen.
[0023] By adopting the above technical solution and setting the deformation band, the screen can be deformed along the circumferential direction. When there is a precision deviation between the taper of the screen and the cone body, the screen can be deformed more easily to adapt to the shape of the cone body.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. The screen is set between the inner wall layer and the outer wall layer of the cone body, so that the screen serves as the skeleton structure of the cone body, strengthens the structure of the cone body, and makes the polyurethane hopper less likely to shrink and deform in a low temperature environment, which is beneficial to ensure the rigidity and impact resistance of the polyurethane hopper.
[0026] 2. The material passing through the hopper is discharged at an angle, which can improve the discharge efficiency of the hopper and reduce the accumulation of materials at the lower end of the hopper, which affects the material unloading efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-6 This application is described in further detail.
[0036] Example 1
[0037] The present application embodiment discloses a conical polyurethane hopper. Figure 1 and Figure 2 The conical polyurethane hopper includes a conical cylinder body 1, which includes an inner wall layer 11 and an outer wall layer 12. A screen 13 is provided between the inner wall layer 11 and the outer wall layer 12. The screen 13 is a conical cylinder structure, and the screen 13 is respectively bonded to the inner wall layer 11 and the outer wall layer 12 by adhesive.
[0038] Reference Figure 1 The port plane of the small end of the cone body 1 is relatively inclined to the port plane of the large end, so that when the hopper is in use, it tilts downward to discharge the material, reducing the accumulation of materials below the hopper and blocking the discharge.
[0039] Reference Figure 1 and Figure 3 The outer wall layer 12 is provided with a first flange 111, and the inner wall layer 11 is provided with a second flange 121. The second flange 121 is farther away from the small end of the cone body 1 relative to the first flange 111. Several hanging components 14 are connected between the first flange 111 and the second flange 121. The hanging components 14 are arranged at equal angles around the center line of the cone body 1.
[0040] The implementation principle of a conical polyurethane hopper in the embodiment of the present application is as follows: a screen 13 is disposed between the inner wall layer 11 and the outer wall layer 12 of the conical cylinder body 1, so that the screen 13 serves as the skeleton structure of the conical cylinder body 1, thereby strengthening the structure of the conical cylinder body 1 and making the polyurethane hopper less susceptible to shrinkage and deformation in a low-temperature environment, which is beneficial to ensuring the rigidity and impact resistance of the polyurethane hopper. The first flange 111 and the second flange 121 are connected by a hanging member 14, so that the first flange 111, the second flange 121 and the hanging member 14 form a relatively stable overall structure, so that the hopper can maintain a stable structural form when hoisted and used, and reduce the deformation of the hopper during use.
[0041] Example 2
[0042] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the inner wall layer 11 and the outer wall layer 12 are connected as one body by injection molding, and the screen 13 is buried and wrapped in the inner wall of the inner wall layer 11.
[0043] The screen 13 is a steel wire mesh. The large end of the cone of the screen 13 has several protruding steel wire ends, which serve as push rods 131. The push rods 131 are buried inside the inner wall layer 11. The push rods 131 are flush with the surface of the second flange 121 away from the first flange 111, and the push rods 131 are relatively inclined to the busbar direction of the screen 13.
[0044] When manufacturing the hopper, the outer wall layer 12 is first injection molded, and then the screen 13 is placed on the inner side of the outer wall layer 12. Then, the inner wall layer 11 is injection molded on the basis of the outer wall layer 12, so that the screen 13 is injection-molded and wrapped in the inner wall layer 11. At the same time, the outer wall layer 12 and the inner wall layer 11 are injection-molded to form a whole, which is conducive to ensuring the integrity of the cone body 1. The push rod 131 can abut against the inner wall of the mold corresponding to the inner wall layer 11, so that the screen 13 can be tightly pressed against the inner circumferential surface of the outer wall layer 12, which is conducive to ensuring the position accuracy of the screen 13.
[0045] It is worth mentioning that, in another embodiment, the top rod 131 can also be a metal rod welded to the screen 13 , or a plastic part bonded and fixed to the screen 13 .
[0046] Example 3
[0047] Reference Figure 6 This embodiment differs from Embodiment 2 in that the screen 13 is provided with an inwardly arched deformation band 132, which extends along the entire length of the screen 13 in the direction of the generatrix. The provision of the deformation band 132 allows the screen 13 to deform circumferentially. When there is a precision deviation between the taper of the screen 13 and the cone body 1, the screen 13 can more easily deform to adapt to the shape of the cone body 1.
[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
