Self-feeding swinging sand-screening device

Abstract

The invention discloses a self-feeding swinging sand-screening device. The self-feeding swinging sand-screening device comprises a base, wherein a second slide rail is fixedly arranged at the top of the base through a support, a screening box is slidably connected to the top of the second slide rail through a slide block, and a first sieve screen and a second sieve screen are fixedly arranged in the screening box; a first slide rail is further fixedly arranged at the top of the base through a support, and a rack is slidably connected above the first slide rail through a slide block; and a fixed plate is further fixedly arranged at the top of the base, a sector gear is rotationally connected to the front end surface of the fixed plate through a first pin shaft; the sector gear is engaged with the rack; a swinging rod is further fixedly connected to the top of the sector gear; a rectangular hole is formed in the swinging rod; a speed reduction motor is fixedly arranged on the rear end surface of the fixed plate; the speed reduction motor is connected with a rotary disc; a second pin shaft is fixedly connected to the top of the front end surface of the rotary disc; and the second pinshaft is located in the rectangular hole in the swinging rod. According to the self-feeding swinging sand-screening device disclosed by the invention, the rack is driven to carry out left-right movement through the swinging of the sector gear, and then the screening box is driven to carry out left-right movement, so that the screening effect is improved, and the screening speed is increased.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a self-feeding swinging sand screening device. Background technique [0002] Sand screening is an indispensable link in the construction process. Many small construction sites only use a net made of iron wire to filter the sand. The efficiency of sand screening is low. The sand screening process wastes time and energy, and the labor intensity is high. ; and although the sand screening machines used in some large-scale construction sites have high sand screening efficiency, their structures are complex and the operation is troublesome. Manual feeding is often required, and the labor intensity is also relatively high. Contents of the invention [0003] The object of the present invention is to provide a self-feeding type swinging sand screening device to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, t...
