Description

Technical Field

[0001] The utility model relates to the technical field of weeding devices, in particular to a cultivated land weeding device. Background Art

[0002] Arable land refers to land that is specifically used to grow crops, is cultivated regularly, and can be harvested normally, including basic farmland with relatively good land conditions and usable arable land with relatively poor land conditions but can be harvested normally without damaging the ecological environment. Arable land is the basic resource and condition on which human beings depend for survival. Weeds are a major pest that affects the agricultural production process. Therefore, weeding has become a top priority in the agricultural production process. When planting on arable land, operations such as weeding, loosening the soil, and irrigation are required.

[0003] The current announcement number CN208987327U discloses "A high mountain cultivated land weeding device", which includes a tractor, a hanger, a cutting and crushing device, a plowing device and a soil crushing device. The hanger is installed at the end of the tractor, the cutting and crushing device is installed on the mounting frame below the end of the hanger close to the tractor, the plowing device is fixed on the bottom surface of the mounting frame, and the soil crushing device is installed on the hanger above the traveling wheel. By setting the cutting and crushing device to cut, the grass in the ground can be quickly cut off, and the cut grass can be poured onto the conveyor belt, and the grass can be crushed with the crusher to avoid the grass occupying space. At the same time, by setting the soil crushing device, the plowed soil can be broken up, and the grass roots remaining in the soil can be scraped out to avoid the grass roots growing again, while reducing the labor intensity of farmers.

[0004] Although the above-mentioned weeding devices have certain advantages in weeding efficiency, they still have certain disadvantages:

[0005] When using the above weeding device, after the weeds are cut, it is not easy to collect the weeds, and the collection efficiency is slow. At the same time, when collecting the weeds, the grass roots are easy to bring out the soil. Collecting the soil in one piece can easily reduce the land soil and reduce land utilization. At the same time, it occupies a large space in the collection box. Utility Model Content
