The unit structure of ear-picking straw crushing

Abstract

The present invention specifically relates to a corn ear picking straw crushing unit structure for harvesting corn ears while crushing straw and returning them to the field. The front end of the unit body structure, the ear picking device installed behind the grain dividing device and the straw crushing device share a pair of crushing rollers. In addition to the two crushing rollers, the ear picking device also includes an ear picking plate installed above the two crushing rollers. The crushing device also includes a plurality of notched disc knives and a slotted hexagonal knife seat installed on the two rollers, and self-aligning bearings are installed near the front ends of the two crushing rollers; the transmission part is mainly composed of The gearbox at the rear provides power for ear picking, straw crushing, and reeling. Compared with the prior art, the present invention has a pair of rollers shared by the ear picking device and the straw crushing device, and the blade and the knife seat are installed on the two rollers respectively, so that the overall structure is compact and the work is reliable, and the harvested ear straws are crushed and returned to the field. Function.

Description

technical field [0001] The invention provides a crushing unit structure of ear-picking straws for harvesting corn ears and crushing straws and returning them to the field, belonging to the technical field of agricultural machinery. Background technique [0002] At present, most corn harvesting machines in my country use returning machines to return the straw directly to the field after ear picking. There are two types of installation positions for the returning machines. The space structure requirements are relatively high, and most machines have insufficient space to install the returning machine at the front; the other is installed at the middle and rear of the machine. When the machine is working with this installation method, part of the corn stalks will be rolled in by the machine's walking wheels. In the field, it cannot be returned to the field by the returning machine. In addition, when the returning machine is working, the power consumption is large and the unit vibr...

Problems solved by technology

[0002]At present, most of the corn harvesting machines in my country use returning machines to return the straw directly to the field after picking ears. There are two types of installation positions for the returning machines, one is Installed at the front of the corn harvester, this installation method has high requirements on the space structure of the machine, and most machines have insufficient space to install the returning machine at the front; the other is installed at the middle and rear of the machine, using this installation When the machine is working, part of the corn stalks are rolled into the field by the walking wheels of the machine, and cannot be returned to the field by the returning machine

In addition, when the returning machine is working, the power consumption is large and the unit vibrates greatly
