Crushing and screening device for road and bridge construction

Abstract

The invention is applicable to the field of road and bridge construction, and provides a crushing and screening device for road and bridge construction. The device comprises a screening box body and a crushing device, a cover plate is arranged on the screening box body, a conveying pipeline is arranged on the cover plate, the screening box body communicates with the crushing device through the conveying pipeline, a plurality of screening boxes, rotating supporting pieces and rod pieces are arranged in the screening box body, a support is arranged on the side, away from the crushing device, of the screening box body, a driving mechanism is arranged on the support, a plurality of first clamping pieces are fixed to the rod pieces in the length direction of the rod pieces, the rotating supporting pieces are rotationally connected to the two sides in the screening box body, and the rotary supporting pieces on the two sides are connected with screening boxes through second clamping pieces. The device has the beneficial effects that the plurality of screening boxes can be driven by the rod pieces to turn over, the screening effect is guaranteed, compared with a conventional vibration mode, the device generates low noise, and due to the fact that the two sides of the screen boxes are clamped to the second clamping pieces, the screen boxes can be taken out rapidly and conveniently.

Description

technical field [0001] The invention belongs to the field of road and bridge construction, in particular to a crushing and screening device for road and bridge construction. Background technique [0002] With the development of society, the infrastructure of transportation is more and more developed, and road and bridge construction is a relatively extensive construction project. [0003] In the process of road and bridge construction, a lot of fillers are used, most of which are stones or stones. In some specific structures, stone fragments of uniform size need to be used for filling, so they are often crushed and screened by crushing and screening devices. The transported stones are crushed and then sieved to obtain uniform stone fragments for filling. [0004] The existing crushing and screening device is to set multiple screen structures in the vertical direction, put the crushed stones into the uppermost screen structure, and then drive each screen structure to vibrate...
