Double-airflow cleaning device of peanut picker

Abstract

The invention discloses a double-airflow cleaning device of a peanut picker. A framed vibrating screen with the high front part and the low rear part is installed inside a rack, a crank connecting rod and a suspender are connected to the front end between the rack and the vibrating screen, a swinging connecting rod is connected to the rear end, a front air suction region and a rear air suction region are sequentially arranged behind a receiving region on a screen plate of the vibrating screen, a front cross flow fan is installed at the portion, above the front air suction region, of the rack, a front air suction hood with an air suction inlet stretching into the front air suction region is arranged on the front cross flow fan, a rear cross flow fan is installed at the portion, above the rear air suction region, of the rack, a rear air suction hood with an air suction inlet stretching to the rear air suction region is arranged on the rear cross flow fan, an air through channel is reserved between the front and rear air suction hoods of the two cross flow fans, and sieve holes are uniformly distributed in the screen plate of the front and rear air suction regions. The double-airflow cleaning device has the advantages of being reasonable in structure and good in disposable cleaning and separation effect, avoiding repeated cleaning, lowering energy consumption, lowering fruit loss rate and saving the production cost.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a double-airflow cleaning device for a peanut picker with high cleaning efficiency, avoiding repeated cleaning and saving production costs. Background technique [0002] The existing peanut picking machine cleaning device, one is completed by a centrifugal fan combined with a conveyor belt with a certain inclination, a secondary recovery device and a vibrating screen, and the other is completed by a centrifugal fan combined with a vibrating screen and a secondary recovery device. Implement cleanup. Their common disadvantage is that during the cleaning and separation process, a small portion of peanuts with light specific gravity are blown out of the machine by the fan, resulting in losses, and a small portion of peanuts failed to roll off and unloaded on the conveyor belt in time, and were sent to the secondary Repeated cleaning and separation on the recovery device leads to a decrease ...

AI Technical Summary

Problems solved by technology

Their common disadvantage is that during the cleaning and separation process, a small portion of peanuts with light specific gravity are blown out of the machine by the fan, resulting in losses, and a small portion of peanuts failed to roll off and unloaded on the conveyor belt in time, and were sent to the secondary Repeated cleaning and separation on the recovery device leads to a decrease in the cleanliness of the peanuts and an increase in the broken rate

In addition, during the cleaning process, the causality and stem roots are not completely separated, and they need to be sent to the secondary recovery device for repeated cleaning and separation, which reduces work efficiency and increases energy consumption and production costs.
