Horizontal root cutting device for grazing degraded Leymus chinensis in typical grasslands

Abstract

The invention discloses a transverse root-cutting device for grazing degraded Leymus chinensis in a typical grassland area. The device has a plug-in cutter that reciprocates along the vertical direction, and can perform root-cutting operations along a direction perpendicular to the traveling direction of the device. , and will not delay the normal travel of the device. Specifically, a track is set on the large walking wheel of the device, and the track laid on the ground between the front and rear wheels is stationary relative to the ground, so the plug-in cutter can Moving and performing cutting operations on the crawler belt, the device is also provided with a longitudinal bar that controls the moving track of the self-propelled cutting device to limit the direction of travel of the cutter and the self-propelled cutting part where it is located, and prevent it from being uneven on the road surface In addition, the device also includes small walking wheels, which can fully compress the track through the small wheel to make the track more smooth and further enhance the adaptability to uneven road surfaces.

Description

technical field [0001] The invention belongs to the technical field of grassland ecological control and restoration, and in particular relates to a transverse root cutting device for grazing and degrading Leymus chinensis 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.

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

[0007] In the applicant's prior patent application No. 2017109652502, the patent document titled Root Cutting Device for Grazing Degraded Leymus Grassland in Typical Grassland Areas describes a device capable of cutting roots horizontally, which was found in practical applications. There are still some defects in the device. The self-propelled cutting part of the device is only limited by the matching relationship between the roller and the groove on the crawler when it is working. In actual use, the self-propelled cutting device is often caused by uneven road surface. Breaking out of the groove track, the electromagnet is energized in an emergency, and the self-propelled cutting device is fixed on the bottom of the main frame, which causes the overall work progress of the device to slow down, and it is often affected by the road surface condition and stops in an emergency, that is, the device is suitable for uneven road surfaces. Less adaptable and too expensive to produce
