A building waste crushing and recycling device

Abstract

This utility model discloses a construction waste crushing and recycling device, including a crushing box. Symmetrically distributed crushing rollers are rotatably connected inside the crushing box. A dust collection box is provided on one side of the crushing box, and a dust collection pipe is fixedly connected to the top of the dust collection box, with the other end of the dust collection pipe fixedly connected to the crushing box. An installation groove is provided on the side of the dust collection box away from the crushing box. During discharge, an electric telescopic rod is activated, and the driving end of the electric telescopic rod drives the limiting rod and the baffle to move, causing the baffle to fail to block the discharge chute, and the dust is guided out through the discharge plate. The motor is then activated, and the output shaft of the motor rotates, driving the transmission shaft to rotate. This, in turn, drives the rotating shaft to rotate through the driven bevel gear and the driving bevel gear. The rotating shaft rotates, causing the discharge plate to move. The discharge plate vibrates through a cam, a telescopic rod, and a second spring, achieving vibration-driven discharge, improving discharge efficiency and facilitating discharge.

Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a building construction waste crushing and recycling device. Background Technology

[0002] Building construction (or housing construction) refers to the various technical work carried out in the reconstruction or expansion of buildings and ancillary structures, including surveying, planning, design, construction, installation, and maintenance, as well as the completed engineering entity. Building construction (or housing construction) refers to the construction of buildings and other structures on land where infrastructure construction has been completed, including residential buildings, industrial plants, commercial buildings, office buildings, and other special-purpose buildings.

[0003] This application improves upon the existing technology. In the existing technology, a lot of waste is generated during building construction, but building construction waste can still be recycled and reused. However, building construction waste needs to be crushed before it can be recycled. Currently, a lot of crushing is still done manually, which generates a lot of dust during the crushing process. Therefore, it not only pollutes the environment, but also causes discomfort to the workers. Utility Model Content

The drive end of the electric telescopic rod 5 drives the limit rod 6 and the baffle 8 to move, so that the baffle 8 fails to block the discharge chute 17. The dust is guided out through the discharge plate 19. The motor 10 is activated. The output shaft of the motor 10 rotates and drives the transmission shaft 27 to rotate. In turn, the driven bevel gear 26 and the driving bevel gear 24 drive the rotating shaft 21 to rotate. The rotating shaft 21 rotates and drives the discharge plate 19 to move. The cam 20, the telescopic rod 22 and the second spring 23 cause the discharge plate 19 to vibrate, realizing the vibration discharge of the discharge plate 19, which improves the discharge efficiency and facilitates the discharge.

[0035] In this application, when the feeding plate 19 moves, it pushes the push rod 18 to move, which causes the push rod 18 to drive the cleaning rod 14 to move. The movement of the cleaning rod 14 drives the cleaning brush 13 to clean the filter screen 12. When the feeding plate 19 moves down, the first spring 16 resets, causing the cleaning rod 14 to move down, which in turn causes the cleaning brush 13 to move vertically back and forth to clean the filter screen 12.
