Problems solved by technology

[0003] The existing screening equipment mainly uses the vibrating motor to drive the movement of the sieve body. The vibration frequency of the vibrating motor brings force between the coal blocks, causing the coal blocks to be shattered, resulting in increased coal slag, and large coal blocks Reduced, resulting in the insufficient supply of coal in the environment where large coal is used, and the sieve body is easy to block during the screening process, resulting in longer screening time and the problem that all coal cannot be collected automatically after screening

Abstract

The invention relates to the technical field of coal production, in particular to a screening device for coal production. The problems that according to existing screening equipment, a vibration motor is mainly used for driving a screen body to move, the vibration frequency of the vibration motor exerts force on coal briquettes, the coal briquettes are shattered, coal briquette disintegrating slag is increased, large coal briquettes are reduced, so that the coal briquettes cannot be sufficiently supplied in a large coal briquette use environment, the screen body is prone to being blocked in the screening process, the screening time is prolonged, and the screened coal briquettes cannot be completely and automatically collected are solved. The screening device comprises a box body, a material falling device is arranged on a screening device body, and an anti-blocking device is further arranged on one side of the screening device body. The screening device body is arranged, the vibration motor is replaced with a mechanical structure, the screening device body moves back and forth to drive the screen body to move back and forth in a small range, and the situation that the number of large coal briquettes is affected due to the fact that the frequency of the vibration motor is too high is prevented.

Description

technical field [0001] The invention relates to the technical field of coal production, in particular to a screening device for coal production. Background technique [0002] Coal is a solid combustible mineral that was gradually formed by ancient plants buried underground through complex biochemical and physicochemical changes. [0003] The existing screening equipment mainly uses the vibrating motor to drive the movement of the sieve body. The vibration frequency of the vibrating motor exerts a force between the coal blocks, causing the coal blocks to be shattered, resulting in increased coal slag, and large coal blocks Reduced, resulting in insufficient supply of coal in the environment where large coal blocks are used, and the sieve body is easy to block during the screening process, resulting in longer screening time and the problem that all coal blocks cannot be collected automatically after screening.
