Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of corn thresher, more particularly, to an agricultural corn thresher. BACKGROUND

[0002] The agricultural corn thresher is a device specially used for separating corn kernels on the ear from the cob. Common types include manual and mechanical threshers. Mechanical threshers usually have two types of roller and air separation, the roller type separates the corn kernels from the cob by rotating the roller, and the air separation type blows away impurities and unthreshed corn kernels by air flow. The selection of suitable thresher should be based on crop size, budget and operating conditions.

[0003] The prior art document with publication number CN111615937B provides an agricultural corn thresher, which feeds corn ears from a feeding hopper, and the corn ears are dispersed to both sides by a dispersion plate. The dispersion plate is pressed by the weight of the corn ears during the dispersion process, causing the top end of the dispersion plate to rotate around the fixed shaft. The normal feeding of the corn ears is ensured by the offset rotation of the dispersion plate itself. The movement of the extrusion rod causes the extrusion rod to rotate downward around the rotating shaft, making the corn ears more uniform during feeding and reducing the direct vertical downward feeding of the corn ears.

[0004] The prior art solution in the above has the following defects: the device is not convenient for screening corn kernels during use, which may cause corn cobs in the corn kernels, thereby affecting the quality of the corn kernels.

[0005] In view of this, we propose an agricultural corn thresher. CONTENT OF THE INVENTION
