A kind of collection method of residual grain automatic collection device

Abstract

The invention discloses a residual grain automatic collecting device and a collecting method, comprising a casing installed at the bottom of a hoist, one side of the hoist is provided with a feeding port, and the other side is communicated with a discharging port of an inclined channel, The feeding port of the inclined channel is communicated with the shell, a suction fan is installed on one side of the inclined channel, a plurality of hoppers are arranged in the elevator, and at least one of the hoppers is provided with a pressure sensor and a magnetic card. The underside of the inside has a magnetic card reader. The invention can realize the automatic collection of the residual grain at the bottom of the bucket elevator, send the collected grain into a specific hopper, and discharge it out of the machine through the lifting of the specific hopper and the three-way valve of the dryer. All schemes are applicable, effectively reducing the number of broken rice that burst due to repeated drying, thereby reducing the waist burst rate, reducing the loss of grain during the drying process, improving the drying quality of grain, and avoiding frequent manual cleaning. Manpower is saved.

Description

technical field [0001] The invention relates to an automatic collecting device and a collecting method, in particular to an automatic collecting device and collecting method of residual grain. Background technique [0002] my country is a big agricultural country, and the annual grain output ranks the highest in the world. After the grain is harvested, it needs to be dried in time for storage. At present, the batch circulating grain dryer plays an increasingly important role in my country's agricultural production. [0003] Bucket elevator is a continuous conveying machine that vertically lifts materials. It has the advantages of large conveying capacity, high lifting height, stable and reliable operation, and long service life. It is widely used in batch cycle grain dryers. However, after a batch of grain is dried, there will always be a part of the grain left at the bottom of the bucket elevator that cannot be lifted. If it is not removed, entering the next batch of dryin...

AI Technical Summary

Problems solved by technology

However, after a batch of grain is dried, there will always be some grain left at the bottom of the bucket elevator that cannot be lifted. If it is not cleared, it will enter the next batch of drying, which will increase the bursting rate and increase the number of broken rice, resulting in food waste. , reduce the drying effect of the dryer

At present, the method of cleaning the residual grain at the bottom of the bucket elevator of the batch circulation grain dryer is manual cleaning. Since the elevator is close to the dryer, the temperature is high, and the grain remains at the bottom of the bucket elevator. The space is narrow and workers are needed. Bending down to clean up many times, the cleaning effect is not ideal, the labor intensity is high, and the bucket elevator needs to be stopped before cleaning, and the work efficiency is low
