All-purpose compact type header of corn harvester

Abstract

The invention relates to an all-purpose compact type header of a corn harvester. The all-purpose compact type header comprises a compact type gain lifting system, an ear picking system, a feeding system of haulm shredding equipment, and a replaceable ear delivery device. Compared with the prior art, the all-purpose compact type header has the advantages of good haulm lodge resistant performance, low ear picking points, high working efficiency and low ear damage rate, can be used between a self-propelled corn harvester and a suspension type corn harvester, improves the benefit on using machines for harvesting corn, and reduces the social cost on using machines for harvesting corn.

Description

technical field [0001] The invention relates to a high-speed harvesting device for corn, in particular to a compact structure, more adaptable to lodging corn, high-speed harvesting of corn, and a compact device that can be used universally between self-propelled corn harvesters and hanging corn harvesters. Corn harvest header. Background technique [0002] Due to the limitation of the structure of the ear picking unit on the header of the general corn harvester, the ear picking speed of the existing harvester is generally low and it is poorly adapted to the working environment where the corn stalks are lodging, and there is also a relatively high rate of ear damage during the working process. High defects, and the corn header and the corn stalk chopping and returning device are used independently, and the chopping device adopts an independent feeding mechanism, which not only makes the structure of the chopping device complex, the working performance is unstable, and it is p...

Problems solved by technology

[0002] Due to the limitation of the structure of the ear picking unit on the header of the general corn harvester, the ear picking speed of the existing harvester is generally low and it is poorly adapted to the working environment where the corn stalks are lodging, and there is also a relatively high rate of ear damage during the working process. High defects, and the corn header and the corn stalk chopping and returning device are used independently, and the chopping device adopts an independent feeding mechanism, which not only makes the structure of the chopping device complex, the working performance is unstable, and it is prone to stalk blockage and tire grinding The stalks caused by pressing the stalks could not be picked up and were crushed, and the soil returning machine was seriously labor-intensive and the blades were damaged quickly. This also increased the weight of the header and increased the installation volume. The minimum operating height of the header and the adjustment range of the stubble height are limited during harvesting operations

[0003] Due to the difference in the interface of the ear collection device and other devices of the existing various suspended corn harvesters and self-propelled corn harvesters, the headers of the two types of corn harvesters cannot be used in common, which improves the production of corn harvesters. Maintenance costs, reduced repair efficiency
