Root cutting device for grazing degraded Chinese wildrye steppe in typical steppe region

Abstract

The invention discloses a root cutting device for a grazing degraded Chinese wildrye steppe in a typical steppe region. The inside of the device can be only provided with an ordinary rotary cutter capable of performing root cutting operation in an advancing direction and can also be provided with an inserted cutter reciprocating in a vertical direction, the inserted cutter can perform root cuttingoperation without moving in the advancing direction, and the normal advancing of the device cannot be delayed; specifically, an advancing wheel of the device is provided with a crawler belt, the crawler belt paved on the ground between a front wheel and a rear wheel is static relative to the ground, the inserted cutter is mounted on the crawler belt, and therefore, the inserted cutter can be static relative to the ground when the device advances as a whole, and the static time is relatively short, but is long enough for performing the root cutting operation once; and the advancing speed of the inserted cutter is higher than the overall advancing speed of the device, so that the advancing of the inserted cutter can be paused for many times and can perform the root cutting operation.

Description

technical field [0001] The invention belongs to the technical field of grassland ecological control and restoration, and in particular relates to a root cutting device for grazing degraded Leymus chinensis grasslands in typical grassland areas. Background technique [0002] my country is rich in grassland resources, with nearly 400 million square hectares of various natural grasslands, accounting for 41.7% of the country's land area, 3.2 times and 2.5 times the area of ​​cultivated land and forest area respectively. The first place in land resources. [0003] However, as of 2007, although protection measures such as grazing prohibition, rest grazing and zoned rotational grazing have been implemented on about 20% of the usable grasslands in the country, due to climate warming, rainfall reduction, long-term overload grazing and human damage, Leading to the serious phenomenon of "three modernizations" (degradation, desertification, and salinization) of grasslands. [0004] Acc...

Problems solved by technology

[0005] In the prior art, in order to complete this work, a rotary cutter is generally used, the direction of rotation is consistent with the direction of travel of locomotives such as tractors, and finally several parallel traces are left on the grass, such as the application number "200910137581.2" A Chinese patent for "a method for improving hardened and degraded grassland and special spring teeth", such as a Chinese patent with the application number "201110353361.0" titled "a compound improvement method for degraded grassland and a special grassland working machine", and another example The application number is " 201210581050.4 " and the name is called the Chinese patent etc. of " grassland root-cutting, fertilization, supplementary sowing and replanting operation machinery"; the schemes recorded in these prior art documents, because the cutter is rotating, in the actual working process, or more At least some soil will be brought out. If it encounters some special geological areas, it will also lead to the phenomenon of overturning and throwing soil, which will greatly disturb the soil of the grassland and easily cause damage to the grassland vegetation and desertification of the grassland soil;

[0006] In addition, according to the records of these prior art solutions, during one stroke of the cutting machine, the cutting marks of root cutting can only extend along one direction, and they are all parallel to each other, and there cannot be cutting marks in multiple directions. needs improvement
