Grassland soil breaking root cutting machine with copying function

Abstract

The invention belongs to the technical field of mechanized improvement of grasslands, and particularly relates to a grassland soil breaking root cutting machine with a copying function. The grassland soil breaking root cutting machine comprises a rack and a transmission mechanism, wherein multiple single root cutting units are arranged on the rack; each single root cutting unit comprises a copying mechanism, a root cutting soil breaking mechanism and a depth limiting mechanism; each copying mechanism comprises a copying guide rod (407), a connecting cover (408), an adjusting nut (409), a copying spring (410), a connecting gasket (406), a first connecting sleeve (401), a first connecting frame (402), a second connecting frame (403), a third connecting frame (404), a fourth connecting frame (405) and a fifth connecting frame (411); each root cutting soil breaking mechanism comprises a root cutting blade disk (202) and a root cutting blade (201); each depth limiting mechanism comprises a depth limiting wheel bracket (503), a depth limiting wheel shaft (502) and a depth limiting wheel (501). According to the grassland soil breaking root cutting machine, root cutting operation is performed according to the flatness of a grassland under the action of the single copying mechanisms, the depths of each root cutting blade in soil can be effectively adjusted, and the consistency of root cutting depths can be ensured.

Description

technical field [0001] The invention belongs to the technical field of grassland mechanization improvement, and in particular relates to a grassland soil-breaking and root-cutting machine with a profiling function. Background technique [0002] my country is rich in grassland resources, and its total amount and per capita possession have reached the first place in other land resources. However, it is roughly estimated that about 56.5% of the grasslands in my country have been degraded at present. The current situation of my country's grassland environment needs to be improved urgently, which is also the key to achieving sustainable development. As the main dominant herbage in my country's typical grasslands and meadow grasslands, the yield of Leymus chinensis has gradually declined in recent years. The soil permeability of Leymus chinensis grassland becomes poor, the water content decreases, and the porosity decreases, which limits the reproduction of Leymus chinensis, whi...

Problems solved by technology

However, there are still some problems with the root cutter based on this principle: for example, when the 9QP-830 lawn root cutter works on the grass, its shaft is easily bent and deformed, and the root cutter is easily damaged.

The root cutter shaft adopts the way of through-shaft transmission, and the root cutter cannot achieve the effect of profiling

When the ground is uneven, the force of the soil on a certain cutter head of the vermiculite increases, and the force of the cutter head on the cutter shaft also increases, which will easily cause the shaft to bend and deform, and then the verticutter cannot be perpendicular to the ground. relationship, the resulting inclination causes the verticillary knife to be subjected to the joint action of radial and lateral forces, which will not only affect the rootcutting effect, but also increase the resistance to the soil; it is more likely to cause damage to the verticillary knife, which will affect the life of the knife and the overall machine stability
