Elevator winnowing pan belt tensioning device capable of fixing and adjusting gap between winnowing pan and base

Abstract

The invention relates to an elevator winnowing pan belt tensioning device capable of fixing and adjusting a gap between a winnowing pan and a base. The elevator winnowing pan belt tensioning device comprises an elevator base and a tensioning component connected with the elevator base in an adjustable mode, and the tensioning component comprises a lower shell and a roller horizontally and rotationally installed on the lower shell. According to the elevator winnowing pan belt tensioning device, when an elevator works, the tensioning device can fix and keep the gap between the winnowing pan and the inner wall of the lower shell when an elevator winnowing pan belt is tensioned; and when the elevator winnowing pan belt is tensioned, the most reasonable working gap between the winnowing pan and the inner wall of the lower shell is always kept, so that the elevator is under the optimal lifting working condition, the working efficiency of the elevator is improved, the abrasion of the elevator winnowing pan is delayed, and the service life of the elevator is prolonged.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a hoist bucket belt tensioning device with a fixed and adjustable gap between the bucket and the base. Background technique [0002] The bucket elevator is widely used in grain production, mining engineering, chemical industry and other fields; the current bucket belt tension of the hoist adopts the design structure based on the adjustment of the base roller, that is, the tension of the bucket belt is realized by adjusting the lifting of the roller. During the adjustment process, the lower shell does not move, so it is impossible to maintain a fixed gap between the pan and the inner wall of the bottom of the machine base during adjustment, resulting in poor use of the hoist; if the gap is too large, the output of the hoist will be low, and if the gap is too small, it will easily It will cause wear and tear on the bucket of the hoist; at the same time, it will easily ca...
