An automatic screening device for construction sand and gravel

Abstract

The invention discloses an automatic screening device for construction sand and gravel, which includes a sieve plate and a frame, a first motor is installed above the frame, and a first transmission rod is fixedly connected to the output end of the first motor. The end of the first transmission rod away from the first motor is rotatably connected with a second transmission rod, and the end of the second transmission rod away from the first transmission rod is rotatably connected with a slider, and the slider is slidably connected with the frame, and the slider An intermittent mechanism is slidably connected inside the block, and a turret is fixedly connected above the intermittent mechanism, and a brushing device is fixedly connected to the surface of the turret, and a baffle is placed below the brushing device, and the baffle is The lower part is fixedly connected with a fixed column, and the fixed column is fixedly connected with the ground. The upper surface of the baffle plate is provided with a blanking hole, and a feeding device is installed inside the blanking hole. There is a sieve frame, and the surface of the sieve frame is clamped with a sieve plate. This automatic screening device has adaptability, high degree of automation, can improve the efficiency of screening materials, and has a simple structure and strong practicability.

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 ...
