Description

TECHNICAL FIELD

[0001] The application relates to the technical field of dust prevention devices, in particular to a dust prevention device for sand and gravel aggregate sorting. BACKGROUND

[0002] Before sand and gravel aggregate is processed, in order to improve economic benefits, the aggregate is screened to sort out aggregates of different sizes for use in appropriate places, but in the process of aggregate sorting, dust flying occurs due to the presence of powder in the aggregate, which not only pollutes the environment but also affects the health of workers.

[0003] In order to reduce dust flying, people have designed a dust prevention device that prevents dust from flying by adsorbing and screening the dust and recycling the aggregate again, but in the prior art, in order to prevent the mesh from being blocked, the screening mesh plate vibrates up and down, which causes dust to fly, so the dust prevention effect is not good. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the application provides a dust prevention device for sand and gravel aggregate sorting to solve the technical problem of poor dust prevention effect caused by the up-and-down vibration of the screening mesh plate in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0016] Further, the elastic supporting assembly further comprises a sliding column fixed on the inner cavity, and the compression spring is sleeved on the sliding column, and the sliding column is in sliding fit with the groove of the moving seat.

[0017] Further, the bottom of the sieve plate is provided with a sliding rail, and a first sliding groove is mounted on the moving seat and in sliding connection with the sliding rail.

[0018] Further, the limiting plate is mounted on the side of the collecting box, and a through hole is formed in the collecting box and provided with a plug, and the limiting plate can limit the plug on the sieve plate.

[0019] Further, the left end of the sieve plate is accommodated in the accommodation groove of the plug, and the right end of the sieve plate is accommodated in the mounting groove of the collecting box.

[0020] Further, the scraping mechanism comprises:

[0021] A driving motor is mounted on the box cover of the collecting box;

[0022] A rotating shaft is connected to the output end of the driving motor and extends into the collecting box;
