Automatic screening device for building gravel

Abstract

The invention discloses an automatic screening device for building gravel. The automatic screening device comprises a screening disc and a rack. A first motor is mounted above the rack, and the outputend of the first motor is fixedly connected with a first transmission rod. The end, away from the first motor, of the first transmission rod is rotationally connected with a second transmission rod,and the end, away from the first transmission rod, of the second transmission od is rotationally connected with a sliding block. The sliding block is in sliding connection with the rack, and an intermittent mechanism is slidably connected in the sliding block. The upper portion of the intermittent mechanism is fixedly connected with a rotary frame, and the surface of the rotary frame is fixedly connected with a material brushing device. A baffle is arranged below the material brushing device, and the lower portion of a baffle is fixedly connected with a fixed column. The fixed column is fixedly connected with the ground, and a material falling hole is formed in the upper surface of the baffle. A conveying device is mounted in the material falling hole, a screening frame is arranged below the conveying device, and the surface of the screening frame is clamped with the screening disc. The automatic screening device has adaptability and is high in automation degree, the material screeningefficiency can be improved, the structure is simple, and high practicality is achieved.

Description

technical field [0001] The invention relates to the technical field of building materials machinery, in particular to an automatic screening device for building sand and gravel. Background technique [0002] Building material machinery refers to various production and mixing molding machinery used in the production of building materials such as cement, cement products, glass, glass fiber, building ceramics and bricks and tiles. The building material machinery industry mainly includes raw material industry, building material production technology research and development industry and production of building materials In the mechanical manufacturing industry of products, sand and gravel are indispensable materials in building materials. When screening sand and gravel, screening devices are often used to screen and isolate large and small sand and gravel. [0003] The existing automatic screening device cannot screen sand and stones of different sizes, has low adaptability, and ...
