A sundry removal device suitable for corn grain harvesting

Abstract

The invention relates to a sundry removal device suitable for harvesting corn grains. The sundry removal device is integrally arranged above the rear end of an ear conveyor and above the front end of a threshing drum in a threshing system; the sundry removal device includes an operation The box and the operation box are connected by the left and right side walls, the top plate, the bottom plate and the rear side plate to form a non-closed space with an open front end. In this non-closed space, a stem pulling mechanism, a cutting mechanism, and a conveying and discharging mechanism are installed in sequence. The invention feeds the broken stalks and the stripped corn leaves and other sundries mixed in the corn ear through the stem pulling mechanism concentrated in the operation box, so as to realize the separation of the ear and the sundries; the fed sundries are thrown to the The cutting mechanism is used for the cutting process, and the cut debris is thrown to the conveying and discharging mechanism, and then conveyed out of the machine, preventing or reducing the debris such as broken stalks and corn leaves from entering the threshing system.

Description

technical field [0001] The invention belongs to a corn harvester and relates to a corn kernel harvesting technology, in particular to a sundries removing device suitable for corn kernel harvesting. Background technique [0002] In the existing corn harvesting operation, the picking of the ear is usually accompanied by the generation of broken stalks / flaked corn leaves, and the phenomenon that the ear, the broken stalk and the corn leaves enter the conveying device at the same time and are sent to the threshing system at the same time. Broken stalks and corn leaves will increase the workload of the threshing system, reduce the efficiency of ear threshing, and reduce the effect of ear threshing, and the broken broken stalks / corn leaves will enter the cleaning system together with the detached kernels, increasing the load of the cleaning device. May seriously affect the cleanliness of the grain (increase the impurity content). SUMMARY OF THE INVENTION [0003] The purpose of...

AI Technical Summary

Problems solved by technology

Broken stalks and corn leaves will increase the workload of the threshing system, reduce the threshing efficiency of the ear, and reduce the threshing effect of the ear, and the broken stalks / corn leaves will enter the cleaning system together with the detached grains, increasing the load on the cleaning device. It may seriously affect the cleanliness of the grain (increase the impurity content)
