Lifting device for a grain dryer

Abstract

The present invention relates to the technical field of grain dryers, and more specifically relates to a lifting device for grain dryers, including a lifting motor, a driving runner, a driven runner, a lifting bucket and a feed gate, and a lifting bucket The positioning pin is fixedly connected with the conveyor belt. The top of the lifting bucket is fixedly connected with an extension plate. The feed gate includes an inclined channel, a switch plate, a No. 1 electric telescopic rod and an exhaust fan. The switch plate is slidingly connected with the inclined channel. There is a pressure sensor on the top, the pressure sensor is electrically connected to the No. 1 electric telescopic rod, and the No. 1 electric telescopic rod is fixedly connected to the bottom surface of the switch plate; the invention improves the tightness of the connection between the inclined channel, the switch plate and the conveyor belt, and effectively prevents grain Falling into the space below the inclined channel, it is crushed and stuck between the conveyor belt and the runner, effectively reducing the waste of grain, avoiding negative impact on the operation of the conveyor belt and runner, and improving the cleaning efficiency of the grain.

Description

technical field [0001] The invention relates to the technical field of grain dryers, in particular to a lifting device for grain dryers. Background technique [0002] The existing grain dryer adopts the method of circulating drying to dry. The process flow is: after the grain enters from the hopper, the moisture is detected in the elevator. The upper auger lifts the grain to the feed sluice, and then falls from the feed sluice into the drying bin for drying. The outlet of the drying bin is connected to the elevator through the grain discharge wheel and the lower auger, so that the grain is circulated and dried, and the moisture detector monitors the standard The grain is discharged from the grain discharge pipe. [0003] Due to the low efficiency of the traditional upper auger to lift the grain and it is easy to cause the grain to be broken during the rising stage, the existing grain dryer gradually adopts the lifting bucket for the lifting and conveying of the grain. Altho...

Problems solved by technology

[0003] Due to the low efficiency of the traditional upper auger to lift the grain and it is easy to cause the grain to be broken during the rising stage, the existing grain dryer gradually adopts the lifting bucket for the lifting and conveying of the grain. Although the lifting and conveying efficiency is improved, the lifting Grain breakage rate in the conveying stage, but it is difficult for the lifting bucket to connect closely with the feed gate. When the grain falls from the lift bucket into the feed gate, part of the grain will easily fall into the space below the feed gate and enter the conveyor belt and the runner. between, crushes the grain, and affects the operation of the runners and conveyor belts
