Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a weeder for crop fields. Background Art

[0002] The weeder used in crop fields is a mechanical device specially used to remove weeds in the fields. This machine is usually equipped with efficient cutting blades or rotating brushes, which can quickly and effectively remove weeds around crops, thereby preventing weeds from competing with crops for nutrients and water, and ensuring the healthy growth of crops.

[0003] When the current weeders for crop fields are used, the blades are generally fixed and the blade position can only be roughly adjusted. In actual weeding, different regions have different plant species, and even the crops planted in a field are different. Therefore, the problem faced in weeding is that the single fixed blade cannot be accurately adjusted according to the different types of crops when dealing with crop fields of different specifications. Therefore, it has certain limitations when used.

[0004] Therefore, we propose a weeder for crop fields to solve the above problems. Utility Model Content

A more precise adjustment means is arranged on the mounting bracket of the blade. A manually adjustable adjustment screw is arranged here. After the rough adjustment, the blade can be fine-tuned more accurately to meet different field weeding needs. A rotating shaft for flipping the blade is also arranged on the mounting bracket of the blade. Through flipping and fine-tuning, the blade can select different cutting points and different cutting angles according to different weed types, so that when cutting and weeding, the wear on the blade can be reduced and the service life of the blade can be increased to solve the problems raised in the above-mentioned background technology.
