Abstract

A device for cutting stubble and guiding stalks for chopping and returning to the field. The technical problem to be solved by the present invention is to design a device for chopping and returning straw to the field to solve the problem of poor cutting effect of the stalks caused by harvesting machines and tools and straw lodging. The problem. In the present invention, the hob is used to cut along the root of the stalks, and the stalk collecting and conveying device concentrates and throws the cut stalks to the straw crushing device, and returns them to the field after crushing. The present invention combines the functions of stalk cutting, throwing, crushing and returning to the field to form a functional unit, which can simultaneously perform stalk cutting, collecting, throwing, crushing and returning to the field at one time; it can be used with self-propelled, The hanging corn combine harvester can be used together with a tractor alone. It has the characteristics of high crushing rate and low power consumption.

Description

Stem cutting guide stalk shredding and returning device

technical field

The invention relates to a device for stalk cutting, guiding stalk chopping and returning to the field, in particular to a device for cutting stalks, guiding stalks, chopping and returning the stalks, which can simultaneously realize the functions of cutting, throwing, crushing and returning the stalks to the field. field of agricultural machinery.

Background technique

At present, the crushing of lodging corn stalks and the breaking of corn root stubble are problems that need to be solved urgently in autumn corn harvesting operations, especially when harvesting with corn combine harvesters or using conservation tillage techniques. In the current corn harvesting process, there are few joint operations of stalk returning and stubble removal. The fallen corn stalks cannot be chopped and returned to the field, which is mainly a problem of the mechanical equipment itself. The existing stubble removal method is stubble removal after returning to the field, that is, the straw returning and stubble removing machine is composed of a field returning machine and a rotary tiller. Complete field return and stubble removal operations. This type of machine basically puts the stalk returning machine and the rotary tiller behind the machine (the hanging type is placed at the rear of the tractor, and there are also self-propelled ones that place the returning machine in the middle of the machine), and there are tractor or combine harvester tires Severe problem of stalk compression, poor cutting effect of stalks, unable to meet agricultural requirements.

Contents of the invention

The object of the present invention is to provide a corn stubble cutting stalk and root stubble crushing device which can overcome the above defects and simultaneously realize the functions of cutting stubble, throwing the stalk, crushing and returning to the field.

The technical solution adopted by the present invention to solve the technical problem is: a device for cutting stubble, guiding stalks, chopping and returning to the field, including a device for crushing stems, transmission 1, transmission 2, transmission 3, a stubble cutter, and collection and transportation of stalks. Device, power input device, side plate, cutter, pipe shaft 1, pipe shaft 2, throwing rubber plate, pallet, screw conveyor, etc. Its features are: it can be used in conjunction with self-propelled and suspended corn combine harvesters; the cutters in the stubble cutter are installed in groups on the tube shaft 1 by bolts, and the tube shaft 1 is horizontally installed on the side plate of the frame, and the stalks are collected The supporting plate and the throwing rubber plate in the conveyor are installed in groups on the pipe shaft 2 by bolts, and the pipe shaft 2 is installed horizontally on the side plate of the frame. ° angles are evenly arranged on the shafts, and each shaft is installed on the side plate; when working, the stubble cutter cuts off the corn stubble along the ground surface, and the cut stubble and stalks are thrown to the In the stalk crushing device, it is chopped by a high-speed rotating crushing knife.

The beneficial effect of the invention is that the functions of cutting the stalk along the root, collecting and throwing, crushing and returning to the field are combined to form a functional unit. Specifically, the corn stubble is cut off by a slow-rotating stubble cutter, and then the cut stubble and stalks are thrown together by the collecting conveyor to the subsequent stalk crushing device, and the corn stubble is crushed by a high-speed rotating chopping tool. The stalks and stubble are chopped. Among them, due to the screw conveyor structure of the stalk collection conveyor, the stalks can be thrown in a concentrated manner, and the operations of cutting, collecting, throwing, crushing and returning the stalks to the field can be performed simultaneously at one time. The first is to solve the problem of root stubble treatment; the second is to solve the problem of the decline in the qualified rate of stalk crushing caused by the tire pressing the stalk; the third is to solve the power consumption caused by the high-speed rotation of the returning knife to improve the effect of returning to the field. serious problem.
