Sand unloading device

Abstract

The invention discloses a sand unloading device. The sand unloading device comprises a sand hopper, a mounting plate, a material tank, a belt pulley, a conveying belt, a driving motor and a motor seat, and is characterized in that the sand hopper is formed by welding section steel; the lower part of the sand hopper is at 30 to 50 degrees; an outlet is formed in the left side of the sand hopper; the mounting plate is fixedly mounted on the left side of the sand hopper and can slide along the sand hopper; the material tank is fixedly mounted at the outlet of the sand hopper; the driving motor is fixedly mounted on the motor seat; the motor seat is fixedly mounted at the right end of the sand hopper; the two ends of the conveying belt are mounted on the belt pulley and are positioned under the sand hopper.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a sand unloading device. Background technique [0002] In the sand treatment section, when the sand is shaken out or sent, there will be a phenomenon that the amount of sand transported in a short period of time is too large, and sometimes the follow-up equipment will be overloaded, affecting the effect of sand treatment or causing failures. In order to avoid this phenomenon, some foundry companies have taken measures to unload sand from the sand storage hopper under the shakeout machine, that is, a section of compact cutting guide trough is added to the belt conveyor, and a limited amount of outlet is adopted at the outlet of the guide trough. , played a certain role. But because there are burrs, small sprues and other pieces of scrap iron in the old sand, when the sharp corners of these scrap iron burrs are scratched on the belt of the belt conveyor, it will damage the belt...

Problems solved by technology

But because there are burrs, small sprues and other pieces of scrap iron in the old sand, when the sharp corners of these scrap iron burrs are scratched on the belt of the belt conveyor, it will damage the belt or even cut it

In addition, due to the different process methods, the phenomenon of overload sand unloading still occurs from time to time
