Problems solved by technology

[0002] Metal materials are widely used in people's life and production. During the processing of existing metals, the metal materials need to be crushed, ground and sieved before further extraction. The metal powder after crushing and grinding is a loose substance. The prior art The metal powder after medium grinding is separated by two opening and closing plates when discharging, so as to open the opening of the grinding device, so that the metal powder falls from the opening to the screening device for screening. During the movement of the opening and closing plates, part of the opening and closing plates The crushed metal on the screen moves with the opening and closing plate instead of falling into the screening device from the opening for screening, which causes the loss of metal powder and reduces the efficiency of metal powder grinding and screening. Therefore, the present invention proposes to solve the above-mentioned problems. A discharge screening device for metal powder grinding

Abstract

The invention discloses a discharging and screening device for metal powder grinding. The discharging and screening device comprises a box body, a discharging device and a screening device. The discharging device comprises two discharging plates, the two discharging plates are rotatably connected to the inner walls of the left side and the right side of the box body respectively, and two gears are engaged with two semicircular gear rings respectively. The screening device comprises a plurality of first springs, and a lifting plate penetrates through a through groove and extends out to make contact with the bottoms of rotating rods. The two gears drive the two semicircular gear rings to rotate respectively when rotating, then the two discharging plates rotate, and the two discharging plates abut against each other when rotating upwards to be in a horizontal state. When metal powder ground in a grinding device needs to be discharged, the two gears rotate to drive the two discharging plates to rotate downwards, and the ground metal powder and metal powder on the two discharging plates fall into the screening device, so that the loss of the metal powder is reduced, and the metal powder grinding and screening efficiency is improved.
