Description

Technical Field

[0001] The present application relates to the technical field of construction waste, and in particular to an automatic screening system for stock waste in a landfill. Background Art

[0002] The existing garbage in a landfill refers to solid waste that already exists but has not yet been processed or cleaned up. It usually refers to the large amount of garbage accumulated in the past, including domestic garbage, construction waste, scrap metal, etc., while construction waste refers to the garbage generated after the demolition and renovation of old concrete houses, such as concrete blocks, sand and gravel blocks, etc. In order to improve environmental protection requirements, it is usually necessary to recycle some of the usable construction waste by crushing it.

[0003] When using the existing automatic garbage screening system, materials such as steel bars are generally removed and then crushed by a crushing device. However, in actual use, the crushing equipment can usually only crush the construction waste once, resulting in large pieces of construction waste remaining after crushing, which will affect the subsequent crushing work of the device, thereby causing damage to the device and reducing work efficiency.

[0030] In this embodiment, there are two crushing rollers 301, which are symmetrically distributed on the inner wall of the crushing box 1. The cross-sectional shape of the guide plate 302 is L-shaped. There are two guide plates 302, which are symmetrically distributed on the inner wall of the crushing box 1, so that the construction waste can be better crushed and better diverted.

[0031] Furthermore, the cross-sectional shape of the mounting plate 303 is L-shaped, one end of the rotating rod 1 305 is rotatably connected to the inner wall of the crushing box 1 through a bearing 1, one end of the rotating rod 2 309 is rotatably connected to the inner wall of the crushing box 1 through a bearing 2, a gear 2 308 is meshed with the outer side of the gear 1 307, a rotating rod 2 309 is fixedly installed on the inner wall of the gear 2 308, and a crushing roller 2 310 is fixedly installed on the outer wall of the rotating rod 2 309, so that the crushing roller 1 306 and the crushing roller 2 310 can be better rotated and the construction waste can be better crushed for the second time.

[0032] Furthermore, the bottom of the crushing box 1 is fixedly connected to the top of the supporting leg 2, a feed hopper is provided at the top of the crushing box 1, a discharge pipe is provided at the bottom of the crushing box 1, a movable door 1 is installed on the front of the crushing box 1, a movable door 2 is provided on one side of the crushing box 1, and one side of the crushing box 1 is fixedly connected to one end of the electric telescopic rod 401.

[0033] A filtering mechanism 4 is arranged inside the crushing box 1 .

[0034] The filtering mechanism 4 includes an electric telescopic rod 401, a pushing plate 402, a telescopic rod 403, a cleaning brush 404, and a filter 405. One end of the electric telescopic rod 401 is fixedly connected to one side of the pushing plate 402, one side of the pushing plate 402 is fixedly connected to one end of the telescopic rod 403, the bottom of the pushing plate 402 is fixedly connected to the top of the cleaning brush 404, and the inner wall of the crushing box 1 is fixedly connected to both ends of the filter 405.

[0035] In this embodiment, there are two telescopic rods 403 , which are symmetrically distributed on one side of the pushing plate 402 , so that construction waste can be better screened and filtered, and the stability of the pushing plate 402 when moving can be effectively increased.

[0036] Furthermore, there are several cleaning brushes 404, which are symmetrically distributed on the push plate 402 and the lower ends are against the upper surface of the filter 405. The cleaning brushes 404 are made of steel brushes, so that the filter 405 can be better cleaned and pushed to the outside of the crushing box 1 for collection and processing, effectively preventing the filter 405 from being blocked during use.

[0037] The implementation principle of the present application is as follows: when work is required, the operator pours the construction waste into the crushing box 1 through the feed hopper provided at the top of the crushing box 1, and the construction waste can be crushed for the first time by starting the crushing roller 301. After crushing, the construction waste can be diverted by installing the guide plate 302. At this time, the motor 304 is started to drive the rotating rod 1 305 to rotate, and the rotating rod 1 305 is driven to rotate to drive the crushing roller 1 306 to rotate. With the rotation of the rotating rod 1 305, the gear 1 307 can be driven to rotate, and the gear 1 307 is driven to rotate to drive the gear 2 308 to rotate. With the rotation of the gear 2 308, the rotating rod 2 309 is driven to rotate, and the crushing roller 2 310 is driven to rotate by the rotating rod 2 309, so that the crushed construction waste can be crushed for the second time, so that the construction waste can be crushed more thoroughly.

[0038] After the construction waste is crushed twice, the filter screen 405 installed inside the crushing box 1 can filter and screen the construction waste. The fine construction waste is discharged through the discharge pipe at the bottom of the crushing box 1, and the larger construction waste will be stored on the filter screen 405. At this time, the electric telescopic rod 401 is started to drive the push plate 402 to move, and the movement of the push plate 402 drives the telescopic rod 403 to retract. As the push plate 402 moves, the larger construction waste can be pushed out, and the cleaning brush 404 can be installed to clean the impurities on the surface of the filter screen 405, effectively preventing the filter screen 405 from being blocked.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
