Description

Technical Field

[0001] The utility model relates to the technical field of grain throwers, in particular to an intelligent remote control auxiliary device for a grain thrower. Background Technique

[0002] A grain thrower, also known as a winnowing machine or a grain winnower, is an agricultural machinery and equipment mainly used to separate impurities in grains, such as rice husks, wheat bran, dust, etc. Its working principle is to throw the grains into the air through the airflow generated by a fan, and perform screening in the air. The heavy grain particles fall, and the light impurities are blown away by the wind, so as to achieve the cleaning and grading of grains.

[0003] The main components of a grain thrower include a feed inlet, a fan, a sieve mesh, a discharge outlet, etc. During operation, the grains to be cleaned are poured into the feed inlet, and the conveyor belt of the grain thrower rotates at a high speed, throwing the grains into the air. Then the fan starts to generate a strong airflow, blowing the grains up and passing them through the sieve mesh. The heavy grains pass through the sieve mesh and fall into the collection container below, while the light impurities are blown away by the wind, thus completing the process of cleaning the grains.

[0004] At present, the grain throwing angle of a grain thrower is fixed. If the grain throwing angle needs to be adjusted, usually the screws of the adjusting foot are manually pulled and rotated to raise or lower the angle of the conveyor belt of the grain thrower. This method has a low degree of automation, the operation of adjusting the grain throwing angle is troublesome, the adjustment efficiency is low, and it is time-consuming and laborious. Therefore, an intelligent remote control auxiliary device for a grain thrower is needed. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide an intelligent remote control auxiliary device for a grain thrower to solve the technical problems that at present, the grain throwing angle of a grain thrower is fixed.
