Stone screening equipment

Abstract

The invention relates to stone screening equipment. The stone screening equipment comprises a bottom plate, a material box arranged on the bottom plate and a bracket distributed in the material box and arranged on the bottom plate, wherein screening mechanisms are arranged on the bracket, and the screening mechanisms can overturn to screen stones falling into the material box and the screening intervals can be adjusted; and the material box is further internally provided with a stain removing mechanism which removes attachments on two opposite side walls of the material box. According to the stone screening equipment, sieve teeth on first sieve plates are matched with the stones to reduce the contact area with the stones, so that the sieve plates are prevented from being damaged due to overlarge bearing force and not prone to stones accumulation; and meanwhile, the load of a motor and a spline shaft is reduced, the first sieve plates can prevent the sieve skips through the coordinationwith sieve skip mechanisms, and the screening quality is guaranteed; a stain removing plate is driven by a hydraulic cylinder to remove the attachments on the material box, so that the material box is ensured to be clean, and the situation of accumulating blockage after long-time operation is prevented; and the positions of the first sieve plates can be randomly adjusted to adapt to different stone screening.

Description

technical field [0001] The invention relates to a screening device, in particular to a stone screening equipment. Background technique [0002] With the vigorous development of urban construction, the supply of stone materials is increasing day by day. At the same time, the quality standards of stone materials are continuously improved. Traditionally, stone materials are screened through screens. The contact area between stone materials and screens is large, and the screens bear too much weight. It leads to the loss of the screen, and at the same time, the combination of the shaft and the motor is too large, which is prone to failure and endangers the safety of workers; adjusting the screening distance by changing the size of the screen hole, the screen hole is too large, resulting in a decrease in the bearing capacity of the screen, It is easy to cause damage to the sieve, resulting in unqualified sieve materials, too small sieve holes, easy to cause stone accumulation, and...
