Corn ear-picking stubble-cutting stem-cutting header capable of breaking off ears from upside

Abstract

The invention belongs to the technical field of corn harvesters and relates to an ear picking device which can be installed on the corn harvesters, in particular to a corn ear-picking stubble-cutting stem-cutting header capable of breaking off ears from upside. The corn ear-picking stubble-cutting stem-cutting header capable of breaking off the ears from upside comprises a roller and plate combined type ear picking unit, a stem pulling and conveying device and a stubble-cutting stem-cutting device. The corn ear-picking stubble-cutting stem-cutting header capable of breaking off the ears from upside is characterized in that the roller and plate combined type ear picking unit is composed of a pair of conveying rollers and a pair of ear baffles arranged below the conveying rollers, and the roller and plate combined type ear picking unit is fixedly connected with a machine frame of a harvest machine and is arranged obliquely in the mode that the front portion is high and the lower portion is low relative to the ground (when the roller and plate combined type ear picking unit is in work); the stem pulling and conveying device is a telescopic rod tooth type mechanism and is arranged behind the ear picking unit; the stubble-cutting stem-cutting device is composed of a stubble-cutting device and a stem-cutting device, the stubble-cutting device is arranged below the ear picking unit, and the stem-cutting device is arranged below the stem pulling and conveying device. According to the corn ear-picking stubble-cutting stem-cutting header capable of breaking off the ears from upside, the bending break principle of manual corn ear picking is simulated, the problem that corns are damaged when an existing stretching and squeezing method is adopted can be thoroughly solved, and ear picking power consumption can be greatly reduced.

Description

technical field [0001] The invention relates to a corn ear picking device suitable for being installed on a corn harvester, and belongs to the technical field of corn harvesting machinery. Background technique [0002] The ear picking device is the key working part of the corn harvester. At present, it can be divided into two types: roller type and plate type according to the working principle. The plate-type ear-picking device is a passive ear-picking device. The root of the corn ear is stuck by the ear baffle plate, and the corn stalk is forcibly pulled off by the stem-pulling roller to achieve the purpose of ear-picking. The device is easy to cause the problems of broken stems and blockages. The working principle of the roller type is to complete the ear picking operation by the stretching and squeezing action of the conveying roller on the corn stalk and ear. In the existing roller-type ear-picking devices, most of the conveying rollers adopt the structure of additiona...

AI Technical Summary

Problems solved by technology

In the existing roller-type ear picking devices, most of the conveying rollers adopt a structure with spiral ribs attached to the surface, which produces a force of squeezing and kneading on the root of the ear, which is very easy to gnaw the ear of corn, and cannot fundamentally solve the problem of the impact of the conveying roller on the ear of corn. crushing and gnawing
