Multifunctional dot, strip type grass root cutter

Abstract

The invention discloses a multifunctional punctuate, strip typed grass root cutter belonging to the technical field of agriculture machinery. The technical proposal includes a frame (9), a suspension frame (1) on the frame (9), a depth wheel (7) and a power system. The invention is characterized in that the power system is connected with one or more than one crank and rocker mechanisms provided with one or more than one cutters(6). The cutter (6) is parallel to the advancing direction of the multifunctional punctuate, strip typed grass root cutter. The machine can not drag the grass out when digging or cause damage to the original vegetation; the invention can carry out selections of punctuate or strip typed root cutting, thereby being able to change the root cutting rate of unit area. The working performance with higher direction leads to maximum results with little effort when improving the grass farm.

Description

technical field [0001] The invention relates to a multi-functional point and strip type forage cutting machine, which belongs to the technical field of agricultural machinery. Background technique [0002] According to the research results of Professor Wang Kun of China Agricultural University, the rhizomes of Leymus chinensis are distributed in the soil layer of 50-200mm or deeper, and the underground horizontal stems can extend up to 1-1.5m per year. The roots of Leymus chinensis, a gramineous forage grass, can be cut off. Since Leymus chinensis has a strong self-multiplication ability, new seedlings can grow from the cut off place. This theory has been confirmed and feasible in the field of agronomic research, but there is no achievement in this aspect in terms of agricultural machinery, so according to this theory, the research on the root-cutting machinery of Leymus chinensis emerges as the times require. [0003] Among the existing relevant agricultural machinery and ...

Problems solved by technology

However, the disc cutter is easily clamped by the soil, and the cutting resistance is large. When the soil is hard, it is difficult to enter the soil. When the soil has a certain moisture content, the clamping force on the disc cutter is greater. The knife will be subject to greater resistance, and even cannot enter the soil, or get stuck in the soil layer, unable to move forward, often affecting normal work

When these machines work normally, although they can break through the soil and cut the turf, they cause great damage to the native vegetation.
