Cutter embedding type stalk pulling, ear picking and straw cutting unit body

Abstract

The invention particularly relates to a cutter embedding type stalk pulling, ear picking and straw cutting unit body which is composed of a millet separating device, an ear picking device, a straw re-cutting device, a transmission portion and the like. The millet separating device is arranged at the forefront end of the whole unit body, and two chain wheels are arranged on the millet separating device. The ear picking device is composed of a pair of ear picking boards and a pair of cutter embedding stalk pulling rollers, wherein the ear picking boards are arranged above the stalk pulling rollers, and the stalk pulling rollers are composed of steel pipes with square sections and straight board cutters embedded into the steel pipes. While ears are picked, straw is cut off. The rear end of the ear picking device is connected with a main gearbox, and the front end of the ear picking device is provided with the millet separating device. Two power transmission chain wheels are arranged above the main gearbox, and the straw re-cutting device is arranged below the stalk pulling rollers and composed of a small gearbox, a cutter throwing blade, a cutter seat and the like. The small gearbox is connected with the main gearbox through a power distributing shaft. Compared with the prior art, cutter embedding type stalk pulling, plate type ear picking and cutter throwing type straw re-cutting are utilized, fruit ears are harvested, and meanwhile the straw is cut into pieces and thrown back to fields.

Description

technical field [0001] The invention specifically relates to a novel stalk-picking and stalk-cutting unit body, which adopts an embedded knife-type stalk-pulling roller to pluck fruit ears and chop stalks while pulling the stalk, and belongs to the technical field of agricultural machinery. Background technique [0002] At present, most of the corn harvesting machines in my country adopt ear-picking rollers and ear-picking plate-style ear-picking methods. The stalks after ear-picking are directly returned to the field by returning machines. The installation positions of the returning machines are generally divided into two types. The front part of the corn harvester, this method has higher requirements on the space structure of the machine, and one is arranged in the middle and rear part of the harvester, which will cause part of the straw to be pressed into the ground by the walking wheels of the machine and cannot be returned to the field; the present invention A knife-inser...

[0002] At present, most of the corn harvesting machines in my country adopt ear-picking rollers and ear-picking plate-style ear-picking methods. The stalks after ear-picking are directly returned to the field by returning machines. The installation positions of the returning machines are generally divided into two types. The front part of the corn harvester, this method has higher requirements on the space structure of the machine, and one is arranged in the middle and rear part of the harvester, which will cause part of the straw to be pressed into the ground by the walking wheels of the machine and cannot be returned to the field; the present invention A kind of knife-inserted stalk pulling roller is designed, which can complete ear picking while pulling the stalk, and at the same time, chop the straw and throw it back to the field
