Rotary type sand sorting and screening equipment

Abstract

The invention relates to sorting and screening equipment, in particular to rotary type sand sorting and screening equipment. The rotary type sand sorting and screening equipment can improve the screening effect and efficiency and can save time and labor. According to the technical scheme, the rotary type sand sorting and screening equipment comprises a base, a bracket, a feeding hopper, an annularsliding rail, sliding blocks, a mesh frame, a connecting block, a telescopic rod, a grip handle, inserting rods, two rollers, first connecting rods, bolts and the like. The base is placed on the ground, an annular wheel groove is formed on the right side of the top of the base, the two rollers are arranged in the annular wheel groove, the first connecting rods are connected to the tops of the rollers, the bolts are connected to the top ends of the first connecting rods, and the bolts are provided with nuts in a threaded mode. According to the rotary type sand sorting and screening equipment,the mesh frame and a chassis are enabled to rotate back and forth by an operator swinging the grip handle front and rear, so that fine sand can be screened out and drop out of the mesh frame, the coarse sand is left on the chassis, and the sand can be sorted and screened efficiently.

Description

technical field [0001] The invention relates to a sorting and screening device, in particular to a sand rotary sorting and screening device. Background technique [0002] In floor construction or home decoration, cement mortar is used for the paving of floors and walls to enhance the adsorption capacity, and sand is a necessary material in cement mortar. Coarse sand and fine sand have different application ranges and effects. Unprocessed sand is often irregular, mixed with sand of different particle sizes, and cannot be directly used in construction. Therefore, construction sand must be classified and screened before it can be used. When the sand is sorted and screened, the operator sets up the screen, scoops up the sand and pours it on the screen, the fine sand falls through the screen to the ground, and the coarse sand stays on the screen, and then lifts the screen after screening Pour out the grit. As the sand on the screen accumulates more and more, the screening effec...

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing sand classification and screening methods that the screening effect and efficiency will gradually decrease over time, and it takes time and effort to shake and lift the screen, the technical problem to be solved is to provide a method that can improve the screening effect and efficiency and save time.
