High-efficiency sand screening machine

Abstract

The invention discloses a high-efficiency sand screening machine. The high-efficiency sand screening machine comprises a support frame. A screening box is mounted at the top of the support frame. An electric control cabinet is mounted at one side of the screening box. A material bin is mounted at the top of the screening box. A discharging opening is formed in the bottom of the material bin. Baffles are mounted at the two sides inside the discharging opening correspondingly and matched for use. One end of each baffle is mounted on a first electric push rod. Servo motors are mounted on the screening box. Supports are mounted on the inner walls of the two sides of the screening box correspondingly. Each support is provided with a rolling roller. An electric heating piece is connected to eachrolling roller in a sleeving manner. Each electric heating piece is composed of an upper aluminum piece, an electric heating wire, heat conduction silica gel and a lower aluminum piece. Partition plates are mounted at the two sides of the support frame correspondingly. The two partition plates are each provided with a second electric push rod. A screening plate is mounted between the two second electric push rods. A screening net is mounted inside the screening plate. An inclined tank is mounted below the screening net. The sand screening machine is compact in structure and high in sand screening efficiency.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a high-efficiency sand screening machine. Background technique [0002] At present, in the fields of sand, coal, etc., it is necessary to separate large-grained lumps and powders. Using artificial sieves has high work intensity and low efficiency, and often does not sieve wet sand cleanly, resulting in a lot of waste. Therefore, a high-speed sieve is designed. Efficient sand screening machines are worth considering. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency sand screening machine to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a high-efficiency sand screening machine, including a support frame, a screening box is installed on the top of the support frame, and an electric con...
