Efficient sand screening device with conveying frame

Abstract

The invention discloses a high-efficiency sand screening device with a conveying frame, which comprises a conveying frame, a sand screening frame and a base arranged from top to bottom; Lifting rollers are provided; the conveying frame is connected to the base through a bracket, a feeding frame is embedded on the top plate of the conveying frame, and a breaking hammer is arranged in the feeding frame; U-shaped Guide rails, a hollow movable block is arranged between the U-shaped guide rails on both sides, and a left and right reciprocating mechanism is arranged on the inner side of the movable block to drive it to move; High drive mechanism. The sand screening device of the present invention can effectively solve the problems of sand agglomeration and concentrated accumulation, and improve the sand screening efficiency; meanwhile, the setting of multi-directional vibration can effectively improve the sand screening effect.

Description

technical field [0001] The invention relates to a sand screening device, in particular to a high-efficiency sand screening device with a conveying frame. Background technique [0002] Sand is a common building material. The quality of the sand directly affects the overall quality of the building. The impurities and stones in the sand need to be filtered out before use. At this time, a sand screening device is required. [0003] A large amount of sand accumulates together and easily forms agglomerates. If it is not treated before screening, it will affect the efficiency of sand screening. Most of the existing sand screening devices are not equipped with mechanisms to solve this problem; the existing sand screening devices are in When feeding, most of the sand is poured directly on the screen, which is easy to cause sand to accumulate on the screen, which is not conducive to the screening. Contents of the invention [0004] The object of the present invention is to provide ...
