Description

Technical Field

[0001] This utility model relates to the field of material collection hoppers, and more particularly to a buffer material collection hopper. Background Technology

[0002] In modern industrial production material conveying and handling systems, hoppers, as a key intermediate storage device, are widely used in many fields such as mining, building materials, chemicals, and food processing. Their main function is to provide storage in the material transportation process.

[0003] In industrial production material handling processes, when materials fall into the hopper, the huge impact force and high-frequency impact over a long period of time cause structural damage such as dents and deformations in the side walls of the hopper and cracks in the welds, shortening the service life of the equipment. Moreover, the material unloading process of the hopper is mostly done manually. Manual unloading is not only inefficient, but also prone to material accumulation and blockage if unloaded in a timely manner. In severe cases, it may even require machine shutdown for cleaning, which greatly affects production efficiency. Therefore, a buffer hopper is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a buffer hopper, which aims to improve the structural damage caused by long-term high-frequency impact from huge impact forces, such as denting and deformation of the hopper sidewall and cracking of welds, which shortens the service life of the equipment. Moreover, the material unloading process of the hopper is mostly done manually. Manual unloading is not only inefficient, but also prone to material accumulation and blockage if unloaded in a timely manner. In severe cases, it may even require machine shutdown for cleaning, which greatly affects production efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-4 This utility model provides an embodiment of a buffer hopper, comprising a hopper body 1, mounting ears 2 fixedly installed on the front and rear sides of both sides of the hopper body 1, and through slots 3 opened on the front and rear sides of both sides of the hopper body 1. Two sets of shock-absorbing plates 4 are provided inside the hopper body 1, and a shock-absorbing component 5 is provided inside the hopper body 1 for damping the shock-absorbing plates 4. A flipping component 6 for flipping the hopper body 1 for unloading material is provided on the left side of the hopper body 1. First, the mounting ears 2 can be fixed in the required position by bolts. Then, the material can be placed inside the hopper body 1. When the material falls on the shock-absorbing plates 4, the shock-absorbing component 5 can prevent the material from damaging the hopper body 1. When too much material accumulates on the shock-absorbing plates 4, the shock-absorbing plates 4 can be flipped by the flipping component 6, thereby discharging the material on top.

[0030] Reference Figure 1-4The damping component 5 includes four sets of fixing blocks 51, which are fixedly installed on the inner wall of the hopper body 1. Fixing rods 52 are fixedly installed at the four corners of the bottom of the damping plate 4. The bottom of the fixing rods 52 extends through to the bottom of the fixing blocks 51 and slides with them. Through the cooperation of the fixing blocks 51 and the fixing rods 52, when material falls onto the damping plate 4, the material will press down on the damping plate 4. The damping plate 4 moves downwards and slides on the surface of the fixing rods 52, thus damping the damping plate 4. The shock absorber has a circular block 53 fixedly installed at the bottom of the fixed block 51, and a spring damper 54 is sleeved on the surface of the fixed rod 52. The top of the spring damper 54 is fixedly installed at the bottom of the shock absorber plate 4, and the bottom of the spring damper 54 is fixedly installed at the top of the circular block 53. Through the cooperation of the circular block 53 and the spring damper 54, the spring damper 54 can be compressed when the shock absorber plate 4 moves to the bottom. At this time, the impact force of the material falling on the shock absorber plate 4 can be effectively reduced under the action of the spring damper 54.

[0031] Reference Figure 1-4The tilting assembly 6 includes four sets of stabilizing rods 61, which are fixedly installed on both sides of the damping plate 4. The outer ends of the stabilizing rods 61 pass through the through slots 3. Gears 62 are fixedly installed on the left ends of two sets of stabilizing rods 61. Two sets of toothed plates 63 are provided on the left side of the hopper body 1. The toothed plates 63 and gears 62 mesh. Through the cooperation of the stabilizing rods 61, gears 62 and toothed plates 63, when too much material accumulates on the damping plate 4, the damping plate 4 will drive the stabilizing rods 61 and gears 62 to move to the bottom. When the gears 62 move to the bottom, they will mesh with the toothed plates 63. When the toothed plates 63 and gears 62 are meshed, the toothed plates 63 can be pulled inward. The toothed plate 63 moves, driving the gear 62, stabilizer bar 61, and damping plate 4 to rotate, thereby discharging the material on the damping plate 4. A limit plate 64 is fixedly installed at the bottom of the toothed plate 63. A reduction motor 65 is fixedly installed on the left side of the hopper body 1. A forward and reverse threaded screw 66 is fixedly installed at the output end of the reduction motor 65. The back of the forward and reverse threaded screw 66 extends through to the back of the limit plate 64. The forward and reverse threaded screw 66 and the limit plate 64 are threaded together. A stabilizing block 67 is rotatably installed on the back of the forward and reverse threaded screw 66. The right side of the stabilizing block 67 and the left side of the hopper body 1 are fixedly installed. Through the limit plate 64, the reduction motor 65, and the gear 62, stabilizer bar 61, and damping plate 4, the material on the damping plate 4 can be discharged. The counter-thread screw 66 and the stabilizing block 67 work together. When the gear 62 falls and meshes with the toothed plate 63, the reduction motor 65 can be started. The output end of the reduction motor 65 drives the counter-thread screw 66 to rotate. The rotation of the counter-thread screw 66 drives the limiting plate 64 to move inward. The movement of the limiting plate 64 inward drives the toothed plate 63 to move inward. The movement of the toothed plate 63 inward can rotate the shock absorber 4, thereby achieving the advantage of automatically discharging the material on the shock absorber 4. Rectangular blocks 7 are fixedly installed on the front and rear sides of the left side of the hopper body 1. A limiting rod 8 is provided on the left side of the hopper body 1. The limiting rod 8 and the limiting plate 64 slide together. The front and rear ends of the limiting plate 64 are fixedly installed on the inner side of the rectangular block 7. Through the cooperation of the rectangular block 7 and the limiting rod 8, the limiting plate 64 can be limited, preventing the limiting plate 64 from rotating due to the influence of the positive and negative screws 66 when it moves, thus preventing the toothed plate 63 from effectively driving the gear 62 to rotate. In addition, the right ends of the two sets of stabilizing rods 61 are fixedly installed with stop blocks 9. The left side of the stop block 9 contacts the right side of the hopper body 1. The stop block 9 can limit the stabilizing rod 61, preventing the stabilizing rod 61 from shaking when it moves up and down, thus preventing the gear 62 from meshing with the toothed plate 63.

[0032] Working principle: First, the mounting ear 2 can be fixed in the required position with bolts. Then, the material can be placed into the hopper body 1. When the material falls on the damping plate 4, the damping plate 4 will move to the bottom and compress the spring damper 54. At this time, under the action of the spring damper 54, the impact force on the damping plate 4 can be reduced, thereby preventing the material from damaging the hopper body 1. When too much material accumulates on the damping plate 4, the damping plate 4 will gradually move to the bottom. The damping plate 4 drives the stabilizer bar 61 and the gear 62. As the gear 62 moves to the bottom, it meshes with the toothed plate 63. When the toothed plate 63 and the gear 62 are meshed, the reduction motor 65 can be started. The output end of the reduction motor 65 drives the positive and negative screw 66 to rotate. The rotation of the positive and negative screw 66 drives the limiting plate 64 to move inward. The movement of the limiting plate 64 drives the toothed plate 63 to move inward. The movement of the toothed plate 63 drives the gear 62, the stabilizer 61 and the shock absorber 4 to rotate. At this time, the shock absorber 4 will flip, thereby achieving the advantage of discharging the material on the shock absorber 4.
