A kind of sand rotary sorting and screening equipment

Abstract

The invention relates to a sorting and screening device, in particular to a sand rotary sorting and screening device. The technical problem to be solved is to provide a sand rotary sorting and screening device that can improve the screening effect and efficiency and save time and effort. The technical solution is: a sand rotary classification and screening equipment, including a base, a bracket, a feeding hopper, a circular slide rail, a slider, a screen frame, a connecting block, a telescopic rod, a handle, an insertion rod, a roller, a first Connecting rods, bolts, etc.; a base is placed on the ground, an annular wheel groove is opened on the right side of the top of the base, and two rollers are arranged in the annular wheel groove. The top of the roller is connected to the first connecting rod, and the top of the first connecting rod is connected to a A bolt is provided with a nut in a threaded manner on the bolt. In the present invention, the operator swings the handle back and forth to make the screen frame and the chassis rotate back and forth, so that the finer sand can be sieved out of the screen frame and the coarser sand remains on the chassis, so that the sand can be efficiently classified and screened.

Description

technical field [0001] The invention relates to a classification and screening device, in particular to a sand rotary classification 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 use ranges and effects. Unprocessed sand is often irregular. Sand mixed with different particle sizes cannot be directly used in buildings. 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, shovels the sand onto the screen, the fine sand falls to the ground through the screen, and the coarse sand remains on the screen. After screening, the screen is lifted up. Pour out the coarse sand. With the accumulation of more and more sand on the stencil, the screening effect ...

AI Technical Summary

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. Labor-saving sand rotary sorting and screening equipment
