Description

Technical Field

[0001] The utility model relates to the technical field of soil loosening and weeding machines, in particular to a soil loosening and weeding machine for leek fields. Background Art

[0002] Leek is a vegetable that people often eat. It is usually planted in bunches. When harvesting, people have to manually step on the ridges to harvest. This will cause the land to be trampled hard after manual harvesting, which will cause the roots of the leeks to suffer from lack of oxygen, necrosis and rot.

[0003] For loosening the soil of leek fields, it is generally done manually with a hoe. This can loosen the soil and remove weeds. However, the weeding efficiency is relatively slow, and the loosening efficiency is also relatively slow. It requires more workers to remove weeds, which will increase the labor cost of loosening the soil and weeding.

[0004] Therefore, for the technical problem described above, there is an urgent need for a leek field loosening and weeding machine. Utility Model Content

[0040] When the utility model is implemented,

[0041] When in use, the gasoline engine 200 is started, and the rotation of the gasoline engine 200 will drive the pulley 405 to rotate through the belt, and the rotation of the pulley 405 will drive the rotating shaft 403 to rotate, and then drive the sprocket 404 on the rotating shaft 403 to rotate, and then the sprocket 404 drives the sprocket 404 on the wheel shaft 401 to rotate through the chain, and then the wheel shaft 401 will rotate along with it, and then drive the driving wheel 406 to rotate, so that the device can move.
