Abstract

The invention discloses a material screening device. A device body, a push-pull door and a sieving device are included. A feeding port is formed in the top end of the device body, and the device bodyis internally of a hollow structure and is internally provided with at least one sieving mechanism, wherein the sieving mechanisms evenly divide the interior of the device body into at least two sieving bins. The positions, located on the front side of the device body, of the top end and the bottom of the device body are provided with opposite sliding rails. The push-pull door is arranged in the sliding rails, one side of the push-pull door is provided with discharging ports corresponding to the sieving bins. The parts, located on the outer side of the push-pull door, of the bottoms of the discharging ports are provided with discharging hoppers. The sieving device is arranged on one side of the device body, one side of the sieving device is connected with a transmission mechanism, and oneend of the transmission mechanism penetrates through the device body and is fixedly connected with a fixing frame. According to the material screening device, screen replacement can be conducted according to needs, the screen number is changed, and accordingly the efficiency of the material screening procedure is improved.

Description

technical field

[0001] The invention relates to the field of material screening, in particular to a material screening device. Background technique

[0002] Material screening is a device for sorting according to the particle size of the material. It is widely used in all walks of life to screen and classify different materials according to different particle sizes, so as to facilitate the storage and sale of materials in the later stage.

[0003] However, the existing material screening devices mostly use single-piece fixed screening, and some factories that require high screening speed adopt the method of mechanical kinetic energy screening. The main representatives are rotary screening machines and vibrating screening machines. During the sieving process of the sieving machine, the discharging and feeding cannot be carried out at the same time. Although the screening speed is increased, the feeding and discharging speed is reduced, and the vibrating sieving machine can si...
