Novel movable and automatic sand screening device

Abstract

The invention provides a novel movable and automatic sand screening device and belongs to the field of building sand screening. The novel movable and automatic sand screening device comprises a shell,a roller and a rotating device. An end cover is arranged at the upper end of the shell and is in threaded connection with the shell. Air vents are formed in the middle of the end cover. The shell andthe end cover wrap a filtering cavity. A rotary shaft is arranged on the right side of a partition plate. The right side of the rotary shaft is fixedly connected to the shell. A lifting hydraulic cylinder is arranged below the left side of the partition plate. A fixing plate is arranged below the lifting hydraulic cylinder and is fixedly connected with the shell. Stirring blades are arranged in the middle of the filtering cavity. The number of the stirring blades is four. A transmission device fixedly connected with the stirring blades is linearly connected with the controller. The transmission device is fixedly connected to the partition plate. The novel movable and automatic sand screening device is simple in structure and convenient to use, the labor cost is effectively reduced, and many labor is saved.

Description

technical field [0001] The invention relates to a construction sand screening device, in particular to a novel movable automatic sand screening device. Background technique [0002] In the field of construction, sand is one of the main building materials. However, the sand raw material contains large particles, which generally need to be screened before use; the sand screening machines currently on the market are large models that can only be used on large construction sites and require a lot of space, and these models are relatively heavy and difficult to move, sometimes the sand is not evenly screened, and the sand screen is not thorough enough; small construction sites rely on manual sand screening, which is very time-consuming and labor-intensive. It is very large, which increases the cost of sand screening, and is not flexible enough, and the large particles screened out contain more fine sand, resulting in a certain waste. Therefore, a new solution must be designed to...
