Description

Grain collector

Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to a grain collector.

Background

Grains such as grains, corn grains and wheat grains can be stored for a long time only by airing, and the grains are required to be filtered once before being stored in a warehouse to remove impurities such as empty shells, dust, dead leaves and the like in the grains. A common machine used for filtration is an agricultural windmill, also known as a grain winnower. In order to save manpower, most of the existing agricultural windmills are electric agricultural windmills, and the electric agricultural windmills are used for driving a rotor blade to rotate instead of manual rotation.

Although the electric agricultural windmill saves manpower to a certain extent, the automation degree is not high enough, grains still need to be collected manually firstly, and then the collected grains are poured into the electric agricultural windmill funnel manually, the process is divided into two steps, the occupied time is long, and the required labor intensity is high.
