A stubble cutting and digging straw root stubble cleaning and crushing device

Abstract

A device for cutting and digging stubble and clearing up and smashing straw stubble comprises a cutting-off clear-up device and a stalk shredding device and the like, can be matched with a self-propelled combine harvester and a suspended combine harvester to be used, and can also be independently matched with a tractor to be used. A mode of installing blades can be adopted for an auger positioned on the cutting-off clear-up device, direct damage to the auger in the clay cutting process is avoided, and the blades are convenient to replace. Each cutter shaft is installed on a side plate. When the device for cutting and digging the stubble and clearing up and smashing the straw stubble is in work, stubble cutting digging is performed through the auger, earth surface clear-up is performed, weeds and scattered stalk (containing lodging stalk) are collected to the middle, the stalk and the stubble are thrown to the stalk shredding device through the cutting-off throwing blades, the stalk is smashed through the stalk shredding device, and machines and tools can simultaneously finish operation of stubble cutting digging, earth surface clear-up, collection of the weeds and the scattered stalk (containing the lodging stalk), stalk smashing and returning to fields and the like in one time.

Description

technical field [0001] The invention relates to a stubble cutting and stubble cleaning and crushing device, especially capable of simultaneously realizing the functions of cutting and digging of stalks, surface cleaning, collection of weeds and loose stalks (including fallen stalks), crushing of stalks and returning to the field The utility model relates to a straw stubble cleaning and crushing device, which belongs to the field of agricultural machinery. Background technique [0002] At present, root stubble removal is an urgent link in summer and autumn harvesting operations, especially when combined harvesting or conservation tillage techniques are used. At present, when harvesting, the stalks have been generally returned to the field, and there are not many stubble removal operations, mainly due to the problem of mechanical equipment. Even if there is stubble removal, the method of stubble removal after returning to the field is adopted, or the field returning machine a...

AI Technical Summary

Problems solved by technology

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 The serious problem of pressing rods is that the cutting effect of the stalks is poor and cannot meet the agricultural requirements. In order to improve the quality of work, especially the part of the stalks that are overwhelmed by the tires, it is necessary to use a high-speed returning motorized knife to remove the stalks from the soil. When it is picked up and shredded, it must cut the soil seriously, which not only causes serious power consumption, but also increases the slip rate of the transmission system due to the obstruction of the soil, causing a series of problems such as a decrease in the speed of the cutter and affecting the quality of the shredding.
