Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically a crushing device for treating agricultural and livestock solid waste. Background Technology

[0002] Agricultural waste refers to organic matter generated during agricultural production, mainly including crop straw and livestock manure. Agricultural waste is organic matter generated during agricultural production and has multiple classification methods and a wide range of resource utilization pathways.

[0003] A search revealed that patent application number 202323265299.7 discloses a crushing device for treating agricultural and livestock solid waste, belonging to the field of solid waste treatment. It solves the problem that the screen of the current crushing device for treating agricultural and livestock solid waste is not easy to clean and is prone to screen blockage when drying the material after crushing. The device includes a crushing unit, a base unit and a screening unit. The base unit includes a screening box that is connected to the crushing unit. The front side of the screening box has an inspection port.

[0004] Although the crushing device for treating agricultural and livestock solid waste uses a motor to drive the crushing rollers to crush the solid waste, and the crushed solid waste falls into the screen box, the crushing rollers of the crushing device only crush the agricultural waste once, which easily leads to incomplete crushing and a large amount of waste accumulating on the screen, which is not conducive to the subsequent discharge of crushed waste.

[0005] Therefore, we propose a compaction device for the treatment of agricultural and livestock solid waste. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a crushing device for treating agricultural and livestock solid waste. It solves the problem that existing devices only crush agricultural waste once, which easily leads to incomplete crushing and subsequent accumulation of large amounts of waste on the screen, hindering the discharge of waste from subsequent crushing processes.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a crushing device for treating agricultural and livestock solid waste, comprising a crushing box, a screening box fixedly installed on the bottom surface of the crushing box, two crushing rollers rotatably installed on the inner wall of the crushing box, two first motors fixedly installed on the outer surface of the crushing box, the output ends of the two first motors respectively penetrating the side wall of the crushing box and fixedly connected to the two crushing rollers, the two crushing rollers rotating in opposite directions, a discharge pipe fixedly installed on the bottom surface of the screening box, and a feeding hopper fixedly installed on the top surface of the crushing box;

[0008] The screening box has a reflux port on its side wall, and a screening component is installed inside the screening box. A reflux component is installed on one side of the crushing box and the screening box, and the two ends of the reflux component are respectively connected to the interior of the crushing box and the screening box.

[0009] The reflux assembly includes a guide hopper, a conveying cylinder, a third motor, a spiral auger, and a reflux pipe. The guide hopper is fixedly installed on the side wall of the screening box and connected to the reflux port. A hollow conveying cylinder is fixedly installed at the end of the guide hopper away from the screening box. A reflux pipe is fixedly installed at the top of the conveying cylinder. The end of the reflux pipe away from the conveying cylinder is fixedly installed on the side wall of the crushing box and connected to the interior of the crushing box. A spiral auger is installed inside the conveying cylinder.

[0010] Preferably, the conveying cylinder has a cross-section with a square outer shape and a circular inner shape. The interior of the conveying cylinder is connected to the guide hopper and the return pipe. The guide hopper and the return pipe are both inclined and in opposite directions. Larger waste materials inside the screening component can enter the interior of the conveying cylinder through the guide hopper. Then, through the rotation of the auger, the larger waste materials can be transported to the return pipe and then re-enter the crushing box for crushing.

[0011] Preferably, a third motor is fixedly installed on the top surface of the conveying cylinder, and the output end of the third motor passes through the top surface of the conveying cylinder and is fixedly connected to the top of the auger. The third motor can drive the auger to rotate.

[0012] Preferably, the screening assembly includes a semi-circular filter plate, a second motor, a shaft, and a semi-circular push plate. The semi-circular filter plate is fixedly installed on the inner wall of the screening box, and the top surface of the semi-circular filter plate is flush with the bottom surface of the return port. The semi-circular filter plate can filter the crushed waste.

[0013] Preferably, a shaft is rotatably mounted on the side wall of the screening box via a bearing ring, and a second motor is fixedly mounted on the side wall of the screening box. The output end of the second motor passes through the side wall of the screening box and is fixedly connected to one end of the shaft. The shaft and the semi-circular filter plate are coaxially arranged, and the shaft can be driven to rotate by the second motor.

[0014] Preferably, the outer surface of the shaft is fixedly equipped with uniformly distributed semi-circular push plates. The side of the semi-circular push plate away from the shaft is in contact with the arc surface of the semi-circular filter plate. Both the surface of the semi-circular filter plate and the semi-circular push plate are provided with uniformly distributed through holes. When the shaft rotates, it can drive the semi-circular push plate to rotate together, thereby pushing the larger waste that has been filtered by the semi-circular filter plate into the return port, and then allowing the larger waste to enter the interior of the return assembly.

[0015] This utility model provides a compaction device for treating agricultural and livestock solid waste. It has the following beneficial effects:

[0016] 1. This crushing device for treating agricultural and livestock solid waste uses a screening component to filter larger waste particles after they have been crushed by the crushing rollers and push them towards the return port. The larger waste particles then pass through the return port and sequentially enter the guide hopper and conveying cylinder. A third motor drives the auger to rotate, which in turn conveys the larger waste particles from the conveying cylinder upwards into the return pipe and crushing box. The larger waste particles are then crushed again by the crushing rollers. This process is repeated until the crushed waste passes through a semi-circular filter plate and is discharged through a discharge pipe. This achieves the purpose of multiple crushing of solid waste, improving the crushing effect and ensuring smooth discharge, preventing blockages. It solves the problem of existing devices where the crushing rollers only crush agricultural waste once, leading to incomplete crushing and accumulation of larger waste particles on the screen, hindering the discharge of subsequent crushed waste.

[0017] 2. This crushing device for treating agricultural and livestock solid waste can filter the crushed waste through a semi-circular filter plate. A second motor can drive the shaft and the semi-circular push plate to rotate together. The larger waste filtered by the semi-circular filter plate is then pushed by the semi-circular push plate into the return port, so that the larger waste enters the interior of the return component. This avoids the crushed waste from clogging the screening box and helps to improve the discharge efficiency of the crushed waste. Attached Figure Description

[0024] Example 1:

[0025] like Figure 1-4As shown: The system includes a crushing box 1, a screening box 2 fixedly mounted on the bottom surface of the crushing box 1, two crushing rollers 12 rotatably mounted on the inner wall of the crushing box 1, and two first motors 13 fixedly mounted on the outer surface of the crushing box 1. The output ends of the two first motors 13 pass through the side wall of the crushing box 1 and are fixedly connected to the two crushing rollers 12. The two crushing rollers 12 rotate in opposite directions. A discharge pipe 21 is fixedly mounted on the bottom surface of the screening box 2, a feeding hopper 11 is fixedly mounted on the top surface of the crushing box 1, a return port 22 is opened on the side wall of the screening box 2, and a screening assembly 3 is arranged inside the screening box 2. The crushing box 1 and the screening box 2 are connected in a series of steps. A reflux assembly 4 is provided on the side. Both ends of the reflux assembly 4 are connected to the interior of the crushing box 1 and the screening box 2, respectively. The reflux assembly 4 includes a guide hopper 41, a conveying cylinder 42, a third motor 43, a spiral auger 44, and a reflux pipe 45. The guide hopper 41 is fixedly installed on the side wall of the screening box 2 and connected to the reflux port 22. A hollow conveying cylinder 42 is fixedly installed at the end of the guide hopper 41 away from the screening box 2. A reflux pipe 45 is fixedly installed at the top of the conveying cylinder 42. The end of the reflux pipe 45 away from the conveying cylinder 42 is fixedly installed on the side wall of the crushing box 1 and connected to the interior of the crushing box 1. The conveying cylinder 43... The internal structure of the conveyor cylinder 42 is equipped with a spiral auger 44. The cross-section of the conveyor cylinder 42 is square on the outside and round on the inside. The interior of the conveyor cylinder 42 is connected to the guide hopper 41 and the return pipe 45. The guide hopper 41 and the return pipe 45 are both inclined in opposite directions. A third motor 43 is fixedly installed on the top surface of the conveyor cylinder 42. The output end of the third motor 43 passes through the top surface of the conveyor cylinder 42 and is fixedly connected to the top of the spiral auger 44. The screening component 3 can filter out the larger waste materials after they are crushed by the crushing roller 12 and push them towards the return port 22. Then, the larger waste materials will pass through the return port 22 and enter the guide hopper 44 in sequence. The waste is fed into the hopper 41 and the conveying cylinder 42. Then, the third motor 43 drives the spiral auger 44 to rotate, which can transport the larger waste inside the conveying cylinder 42 upward and into the return pipe 45 and the crushing box 1 in sequence. Then, the larger waste will be crushed again by the crushing roller 12. The waste is crushed multiple times until the crushed waste passes through the semi-circular filter plate 31 and is discharged through the discharge pipe 21. This achieves the purpose of crushing the solid waste multiple times, so as to improve the crushing effect of the solid waste and ensure that the crushed solid waste is discharged smoothly and avoids blockage.

[0026] Example 2:

[0027] like Figure 2-4As shown: The screening assembly 3 includes a semi-circular filter plate 31, a second motor 32, a shaft 33, and semi-circular push plates 34. The semi-circular filter plate 31 is fixedly installed on the inner wall of the screening box 2, and the top surface of the semi-circular filter plate 31 is flush with the bottom surface of the return port 22. The shaft 33 is rotatably mounted on the side wall of the screening box 2 via a bearing ring. The second motor 32 is fixedly installed on the side wall of the screening box 2. The output end of the second motor 32 passes through the side wall of the screening box 2 and is fixedly connected to one end of the shaft 33. The shaft 33 and the semi-circular filter plate 31 are coaxially arranged. The outer surface of the shaft 33 is fixedly mounted with evenly distributed semi-circular push plates 34. The semi-circular push plates 34 are far from the outer surface of the shaft 33. One side of the shaft 33 is in contact with the arc surface of the semi-circular filter plate 31. The surfaces of the semi-circular filter plate 31 and the semi-circular push plate 34 are provided with evenly distributed through holes. The crushed waste can be filtered through the semi-circular filter plate 31. The second motor 32 can drive the shaft 33 and the semi-circular push plate 34 to rotate together. Then, the larger waste filtered by the semi-circular filter plate 31 is pushed into the return port 22 by the semi-circular push plate 34, so that the larger waste enters the interior of the return assembly 4. This avoids the crushed waste from clogging the interior of the screening box 2 and helps to improve the discharge efficiency of the crushed waste.

[0028] The working principle and usage process of this utility model: In use, the solid waste for agricultural and livestock solid waste treatment crushing device involves feeding solid waste into the crushing box 1 through the feeding hopper 11. Then, two first motors 13 are started, driving two crushing rollers 12 to rotate, thus crushing the solid waste. The crushed solid waste then enters the screening box 2. Smaller waste particles pass through the semi-circular filter plate 31 and are discharged through the discharge pipe 21, while larger waste particles are filtered down by the semi-circular filter plate 31. Simultaneously, the second motor 32 is started, driving the shaft 33 to rotate. The shaft 33 then drives the semi-circular push plate 34 to rotate as well. 4. Larger waste filtered by the semi-circular filter plate 31 can be pushed towards the return port 22. The larger waste will then pass through the return port 22 and enter the guide hopper 41 and the conveying cylinder 42 in sequence. Then, the third motor 43 is started to drive the spiral auger 44 to rotate, which will transport the larger waste inside the conveying cylinder 42 upward and into the return pipe 45. Finally, the larger waste in the return pipe 45 will enter the crushing box 1. The larger waste will then be crushed again by the crushing roller 12. The waste is crushed multiple times until the crushed waste passes through the semi-circular filter plate 31 and is discharged through the discharge pipe 21.
