Description

Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, and in particular to a solid waste treatment device for environmental protection construction. Background Art

[0002] Solid waste refers to solid and semi-solid waste materials generated by human beings in production, consumption, life and other activities. In layman's terms, it is "garbage". Existing solid waste is generally treated by direct landfill. Since solid waste contains contaminated liquid, direct landfill will cause liquid to seep into the ground, which will pollute the environment. In addition, direct landfill of untreated solid waste will cause large solid waste volume and occupy a large area, so it needs to be crushed. The patent with publication number CN115301330B proposes a solid waste treatment device for environmental protection construction, including a device body, a treatment platform is fixedly arranged on the top of the device body, a large particle crushing bin and a small particle crushing bin are fixedly arranged on both sides of the bottom of the treatment platform, a large-toothed crushing wheel is fixedly arranged inside the large particle crushing bin, and a small-toothed crushing wheel is fixedly arranged inside the small particle crushing bin; a vibrating screen plate is movably arranged in the middle of the device body, and a guide slide plate is fixedly arranged on one side of the device body. The vibrating screen plate and the guide slide plate are both inclined, and the vibrating screen plate and the guide slide plate are combined in a Y-shaped cross arrangement. The invention uses a large-toothed crushing wheel and a small-toothed crushing wheel to crush waste to different degrees. The guide slide guides the waste to fall on the vibrating screen plate for screening again. Solid waste that does not meet the particle size is crushed repeatedly, ensuring the quality of solid waste treatment and facilitating waste recycling... However, each time the material enters the compression bin for compression in the device, it can only be compressed once and then taken out, and then compressed again. The material cannot be continuously compressed and automatically sent out. Therefore, a new solid waste treatment device for environmental protection construction is proposed.

A connecting component 23 is arranged in the middle position of the upper surface of the switch plate 15. When the compression plate 18 is pushed out, the connecting component 23 is connected to the compression plate 18. When the compression plate 18 is retracted, the compression plate 18 drives the switch plate 15 to move and open. A conveyor belt 7 is arranged below the fixed box 13, and a discharge port 16 is opened on the bottom side wall of the processing box 1. One end of the conveyor belt 7 extends to the outside through the discharge port 16.

[0018] The linkage mechanism includes a gear assembly 4 and a linkage vibration assembly 5. The gear assembly 4 includes two transmission gears, which are respectively connected to the rotating shafts of the two crushing rollers 11 extending to the outside of the processing box 1.

When the compression plate 18 retracts to a position where the proximity sensor 22 can sense, the proximity sensor 22 feeds back a signal to the controller (not shown in the figure), and the annular electromagnet 231 is instantly energized, so that the tilting block 232 is separated from the compression plate 18, so that the switch plate 15 returns to its original position again.

[0021] A push plate 17 is provided on the top of the fixed box 13, and a linkage push mechanism 19 is provided on the top of the push plate 17. The linkage push mechanism 19 is connected to the switch plate 15. The linkage push mechanism 19 includes a first rack 191, a second rack 193 and a gear 192. The first rack 191 and the second rack 193 are respectively located on both sides of the gear 192 and are meshed with the gear 192. The first rack 191 is fixed to the upper surface of the push plate 17, and a connecting rod 194 is connected to the top of the second rack 193. A rotating rod 195 is provided above the connecting rod 194. The rotating rod 195 is rotatably connected to the inner wall of the processing box 1, and the two ends of the connecting rod 194 are respectively connected to a pull rope 196. The two symmetrical side walls of the fixed box 13 are provided with a sliding opening 21, and the two symmetrical side walls of the switch plate 15 are connected with a connecting block 20. The connecting block 20 passes through the sliding opening 21 and is slidably connected to the sliding opening 21. One end of the pull rope 196 passes through the rotating rod 195 and is connected to the connecting block 20.

[0022] Working principle: When in use, solid waste is put into the crushing chamber 10 through the feed port 2, and the two crushing rollers 11 rotate in opposite directions to crush the solid waste. When the crushing rollers 11 rotate, under the action of the linked vibration component 5, the cam 6 rotates and intermittently contacts the vibration plate 8, thereby driving the screening plate 12 to rotate to achieve screening. The screened solid waste falls into the fixed box 13. When the solid waste is full (a full material sensor can be installed inside the crushing chamber 10 to detect whether the solid waste inside the fixed box 13 is full), the telescopic cylinder 14 is started, and the telescopic cylinder 14 drives the compression plate 18 to move to compress the solid waste. When the compression plate 18 moves to contact with the connecting component 23, it can pass through the tilting block 232, so that the tilting block 232 reaches the side of the compression plate 18 close to the telescopic cylinder 14. After the compression is completed, the telescopic cylinder 14 retracts, and the compression plate 18 retracts. At the same time, under the action of the connecting component 23, the switch plate 15 can be driven to move to open the switch plate 15. Figure 3 In the state shown, when the switch plate 15 is opened, it can link and drive the pull rope 196 to move, so that the pull rope 196 moves up, and at the same time drives the second rack 193 to move up, so that the first rack 191 drives the push plate 17 to move down, which plays a role in assisting the compressed solid waste to be pushed down.

[0023] like Figure 2 As shown, at this time, the pull rope 196 is on the right side of the second rack 193. Therefore, when the switch plate 15 is partially opened, the pull rope 196 moves to the left side of the second rack 193 at the same angle as on the right side. The switch plate 15 is opened to a size that allows the compressed solid waste to fall. At this time, the second rack 193 will not move upward. When the switch plate 15 continues to move backward, as shown in FIG. Figure 3 As shown, at this time, the angle between the pull rope 196 and the second rack 193 is further increased, so that the second rack 193 moves upward, driving the push plate 17 to push downward, thereby avoiding the phenomenon of compressed solid waste not falling off.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
