Description

technical field [0001] The invention relates to a cleaning machine and belongs to the field of agricultural machinery. Background technique [0002] Due to the cold climate in winter in the northwest grape-growing areas, it is easy to frostbite or freeze the vines to death. In order to keep the grapes from freezing to death, it is necessary to remove the vines from the shelves in winter and bury them in the soil to prevent the cold. In the next spring, due to the concentrated time for grape soil clearing and the large area of ​​soil clearing, it is often difficult to hire workers due to lack of labor; Spiral auger and scraper-type earthmovers have appeared, but because the auger and scraper are rigid materials, it is easy to damage the vines, or even cut off the vines; there are also many brush-type earthmovers on the market, but due to various Due to the special terrain structure and cultivation mode of the region, the existing brush-type soil cleaning machine has low soil...

AI Technical Summary

Problems solved by technology

[0003] The invention proposes a cleaning machine, which is suspended on the rear side of the tractor. When working, the soil cleaning brush touches the soil, throws the soil to the middle of the grape row according to its movement track, and adjusts the different stretches through the telescopic hydraulic cylinder. Out of the distance, the height adjustment hydraulic cylinder adjusts the working height to complete the cold-proof soil cleaning, which can solve the problems of easy damage to the vines, low work efficiency and difficult operation of the existing machinery, and has the advantages of high work efficiency, stable work and simple operation.
