Description

Technical Field

[0001] This solution belongs to the field of crushing devices, specifically involving a crushing device for solid waste concrete treatment. Background Technology

[0002] Solid waste concrete is concrete made by using solid waste as a partial raw material to replace traditional materials. It has environmental and economic benefits, effectively solves the problem of solid waste treatment, and reduces production costs.

[0003] A search revealed a utility model patent application with publication number CN214132035U, which discloses a waste concrete crushing device, belonging to the field of concrete processing technology. The waste concrete crushing device includes a crushing box, a crushing working cabinet, and a motor working cabinet. The crushing box has the crushing working cabinet and the motor working cabinet on its front side. The crushing working cabinet is located above the motor working cabinet. A fixed shaft is provided on the left side of the crushing working cabinet, and a first drive motor is fixedly connected to the outer wall of the fixed shaft.

[0004] In existing technologies, most solid waste concrete crushing devices are single-function devices, only capable of crushing. The crushed concrete is inconvenient to transport and lacks simultaneous screening capabilities, resulting in cumbersome and inefficient subsequent processing procedures. Therefore, developing a solid waste concrete processing crushing device that integrates crushing, transportation, and screening functions is of significant practical importance. Utility Model Content

[0005] The purpose of this solution is to provide a crushing device for solid waste concrete treatment, in order to solve the problem that existing solid waste concrete crushing devices can only perform the crushing function.

[0006] To achieve the above objectives, this solution provides a crushing device for solid waste concrete treatment, including a base, a crushing mechanism mounted on the base, a screening mechanism mounted on the crushing mechanism, a support frame fixedly mounted on the base, a housing at one end of the support frame, a crushing roller rotatably connected to the inner wall of the housing, an mounting plate fixedly mounted on the base, a first conveying roller rotatably connected to the mounting plate, a motor fixedly mounted on the side of the mounting plate, a second conveying roller fixedly mounted on the end of the motor shaft passing through the mounting plate, and a conveyor belt meshing with the first and second conveying rollers. The screening mechanism includes a vertical plate fixedly mounted on the side of the housing, a sliding rod slidably mounted on the vertical plate, an installation frame at one end of the sliding rod, a frame body inserted into the installation frame, and a filter screen mounted on the inner wall of the frame body.

[0007] The principle of this scheme is as follows: solid waste concrete is placed into the container, then the motor is started. The motor drives the second conveyor roller to rotate. The second conveyor roller drives the rotating rod to rotate through the first gear and the first gear ring. When the rotating rod rotates, it drives the left second gear to rotate through the fourth gear and the third gear. The left second gear meshes with the right second gear, which drives the crushing rollers on both sides to rotate. The crushing rollers on both sides crush the solid waste concrete. The crushed solid waste concrete falls through the bottom of the container into the filter screen on the inner wall of the frame. When the rotating rod rotates, it drives the eccentric wheel to rotate. Due to the action of the spring... The rollers are always in contact with the eccentric wheel. When the eccentric wheel rotates, it drives the frame inside the mounting frame to move back and forth in a straight line. The frame screens the crushed solid waste concrete through the filter screen. The screened solid waste concrete falls onto the conveyor belt. At the same time, when the second conveyor roller rotates, it also drives the conveyor belt through the first conveyor roller. The conveyor belt transports the crushed solid waste concrete to the designated position. Through the above settings, the purpose of multi-purpose machine is achieved. Compared with the existing technology, this solution realizes the function of crushing, transfer and screening in one unit, which is conducive to improving the processing efficiency of solid waste concrete.

[0008] The technical advantages of this solution are as follows: by setting up a crushing mechanism, it achieves the purpose of crushing solid waste concrete, and also has the ability to synchronously drive the conveyor belt. This design facilitates the rapid transfer of crushed solid waste concrete and effectively improves the efficiency of the processing flow.

[0009] By incorporating a screening mechanism that can be activated in conjunction with the crushing mechanism during operation, the crushed solid waste concrete can be screened in real time, laying a solid foundation for the subsequent refined treatment of solid waste concrete and significantly enhancing the practicality and efficiency of the overall treatment solution.

[0010] Furthermore, a rotating rod is rotatably connected to the base via a bearing, and a first toothed ring is provided on the rotating rod. A first gear is fixedly installed at one end of the second conveying roller, and the first gear meshes with the first toothed ring. The first gear is provided for meshing with the first toothed ring.

[0011] Furthermore, there are at least two crushing rollers, one end of which penetrates the surface of the housing and is fixedly mounted with a second gear. The crushing rollers are used for crushing solid waste concrete.

[0012] Furthermore, the second gear includes a left second gear and a right second gear, which mesh with each other. A third gear is provided on one side of the left second gear, and a fourth gear is fixedly installed at the top of the rotating rod, meshing with each other. By providing the third and fourth gears, the rotation of the rotating rod drives the left second gear to rotate.

Detailed Implementation

[0023] The basic implementation examples are as follows: Figures 1-5As shown: A crushing device for solid waste concrete treatment includes a base 1, on which a crushing mechanism 2 is installed. The crushing mechanism 2 serves to crush the solid waste concrete and simultaneously drives a conveyor belt 22 for transmission, facilitating the transportation of the crushed solid waste concrete. The crushing mechanism 2 includes a support 28, which is fixedly installed on the base 1. The support 28 supports a housing 210. The housing 210 is located at one end of the support 28, with an open top. The inner wall of the housing 210 rotates... A crushing roller 214 is dynamically connected to the base 1. The crushing roller 214 is used to crush solid waste concrete. A mounting plate 21 is fixed on the base 1. The mounting plate 21 is used to support the installation of the first conveyor roller 29. The first conveyor roller 29 is rotatably connected to the mounting plate 21. A motor 24 is fixedly installed on the side of the mounting plate 21. The motor 24 is used to drive the second conveyor roller 23 to rotate. The shaft end of the motor 24 passes through the mounting plate 21 and is fixedly installed on the second conveyor roller 23. A conveyor belt 2 is meshed with the first conveyor roller 29 and the second conveyor roller 23. 2. A conveyor belt 22 is provided for transporting crushed solid waste concrete. A rotating rod 26 is rotatably connected to the base 1 via bearings. The rotating rod 26 is cylindrical and has a first toothed ring 27. A first gear 25 is fixedly installed at one end of the second conveyor roller 23. The first gear 25 meshes with the first toothed ring 27. By providing the first gear 25 and the first toothed ring 27, the rotation of the second conveyor roller 23 drives the rotating rod 26. There are at least two crushing rollers 214, one end of which penetrates the housing 210. A second gear 212 is fixedly installed on the surface. The second gear 212 facilitates the synchronous rotation of the two crushing rollers 214. The second gear 212 includes a left second gear and a right second gear. The left second gear meshes with the right second gear. A third gear 213 is provided on one side of the left second gear. A fourth gear 211 is fixedly installed on the top of the rotating rod 26. The third gear 213 meshes with the fourth gear 211. The arrangement of the third gear 213 and the fourth gear 211 serves to drive the left second gear to rotate when the rotating rod 26 rotates.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a screening mechanism 3 is provided on the crushing mechanism 2. When the crushing mechanism 2 is working, the screening mechanism 3 is driven to move synchronously, thereby achieving the purpose of screening the crushed solid waste concrete, which is beneficial for the subsequent processing of the solid waste concrete. The screening mechanism 3 includes a vertical plate 37, which is fixedly installed on the side of the housing 210. The vertical plate 37 is used to support the sliding of the slide rod 36. The slide rod 36 is slidably mounted on the vertical plate 37. One end of the slide rod 36 is provided with a mounting frame 38, which supports the installation of the mounting frame 38. A frame body 33 is inserted into the mounting frame 38, which supports the filter screen. The frame 33 has a filter screen on its inner wall. One end of the slide rod 36 has a limit plate 34, which is circular. A spring 35 is fixedly installed on the side of the limit plate 34. The spring 35 is used to apply force to the roller 32, so that the roller 32 always rolls on the eccentric wheel 31. The spring 35 is wrapped around the surface of the slide rod 36. One end of the spring 35 is fixedly connected to the vertical plate 37. The side of the mounting frame 38 has a roller 32. The rotating rod 26 has an eccentric wheel 31. The roller 32 rolls on the eccentric wheel 31. The eccentric wheel 31 is used to drive the roller 32 to make reciprocating linear motion when the rotating rod 26 rotates.

[0025] The specific implementation process of this utility model is as follows: Solid waste concrete is placed into the box 210, and then the motor 24 is started. The motor 24 drives the second conveyor roller 23 to rotate. The second conveyor roller 23 drives the rotating rod 26 to rotate through the first gear 25 and the first gear ring 27. When the rotating rod 26 rotates, it drives the left second gear to rotate through the fourth gear 211 and the third gear 213. The left second gear meshes with the right second gear, which drives the crushing rollers 214 on both sides to rotate. The crushing rollers 214 on both sides will crush the solid waste concrete. The crushed solid waste concrete will fall into the filter screen on the inner wall of the frame 33 through the bottom opening of the box 210. When the rotating rod 26 rotates, it will drive the eccentric wheel 31 to rotate. Due to the spring 35 The roller 32 is always in contact with the eccentric wheel 31. When the eccentric wheel 31 rotates, it drives the frame 33 on the inner wall of the mounting frame 38 to move back and forth in a straight line through the roller 32, thereby achieving the purpose of shaking the frame 33. During the movement, the frame 33 will screen the crushed solid waste concrete through the filter screen. The screened solid waste concrete will fall onto the conveyor belt 22. At the same time, when the second conveyor roller 23 rotates, it will also drive the conveyor belt 22 through the first conveyor roller 29. The conveyor belt 22 will transport the crushed solid waste concrete to the designated position. Through the above settings, the purpose of multi-purpose machine is achieved. Compared with the prior art, this solution realizes the function of crushing, transfer and screening in one unit, which is conducive to improving the processing efficiency of solid waste concrete.

[0026] This solution incorporates a crushing mechanism 2 to crush solid waste concrete and also has the ability to synchronously drive the conveyor belt 22. This design facilitates the rapid transfer of crushed solid waste concrete, effectively improving the efficiency of the processing flow. Simultaneously, the inclusion of a screening mechanism 3 allows for simultaneous operation of the crushing mechanism 2, enabling immediate screening of the crushed solid waste concrete. This lays a solid foundation for the subsequent refined processing of solid waste concrete and significantly enhances the practicality and efficiency of the overall treatment solution.
