Cutting, shifting and blocking preventing device

Abstract

The invention discloses a cutting, shifting and blocking preventing device, and belongs to the technical field of agricultural machinery. The cutting, shifting and blocking preventing device comprises a spindle, connecting sleeve plates, inclined plates, a breaking and cutting device and stubble shifting and blocking preventing devices, wherein the breaking and cutting device is mounted in the middle of the spindle, two groups of stubble shifting and blocking preventing devices are symmetrical about the breaking and cutting device and connected to two ends of the spindle, stubble shifting wheels of the stubble shifting and blocking preventing devices and breaking and cutting discs of the breaking and cutting device form deflection angles, and accordingly, the two symmetrical stubble shifting wheels are mounted on two sides of the end part of the breaking and breaking and cutting device in a splayed manner and simultaneously backwards shift stubble and laterally push stubble, straw and weeds; the connecting sleeve plates are symmetrically connected between the breaking and cutting device and the stubble shifting and blocking preventing devices on the spindle and are simultaneously connected with the stubble shifting and blocking preventing devices respectively; and during working, the two connecting sleeve plates are connected with a no-tillage planter for corn ridge culture respectively. The device can cut the stubble, straw and weeds, can shift the stubble, can throw the straw, the stubble and the weeds to the rear side and can push the straw, the stubble and the weeds to furrows on two sides, a clean seed bed is formed on a ridge, blocking is reduced, and the breaking and cutting quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of no-tillage seeders, in particular to a cutting and anti-blocking device, which is suitable for no-tillage seeder for corn ridge cultivation in Northeast China. Background technique [0002] In recent years, conservation tillage technology has been widely promoted and used in my country, and no-tillage seeder is an important tool for conservation tillage. Although the current no-till planter has been greatly developed, there are still many problems, which affect the popularization of no-till planter and the development and promotion of conservation tillage. The main problems of the no-tillage planter for corn ridge cultivation in Northeast China are: some machines destroy the original ridge and form new furrows, the weight is overweight, and the ridge platform is flattened, which affects the growth of crops. The most prominent problem is to maintain the ridge shape. When sowing in ridge farming, the groun...

Problems solved by technology

Although the current no-tillage planter has made great progress, there are still many problems, which affect the popularization of no-tillage planter and the development and promotion of conservation tillage.

The main problems of the no-tillage corn ridge planting machine in Northeast China: some machines destroy the original ridge, form a new ditch, overweight, flatten the ridge platform, affect the growth of crops, and the most prominent problem is to maintain the ridge shape

The notched disc knife has a certain impact and is easier to cut stubble, but there is a missing cutting area in the notch of the notched disc knife, which makes it impossible to cut to the bottom of the stubble at the largest gap; the stubble cutting resistance and power of the corrugated disc knife The consumption is large, and due to the shape of the corrugated disc cutter, the seed ditch is relatively large

After analysis and research, foreign products generally have relatively good wear resistance and relatively high reliability, and the stubble breaking effect is also relatively good, but the price is expensive

The research on stubble breaking and anti-blocking of no-tillage planters in my country is still in its infancy, and the main research work is still concentrated on the research on the overall stubble breaking mechanism. There are few researches on the production technology of the disc blade stubble breaking function, which leads Domestic stubble breaking knives have a large gap with foreign products in terms of product wear resistance, reliability, and product stubble breaking effect, which to a certain extent restricts the promotion and promotion of conservation tillage in my country. develop
