Description

Technical Field

[0001] The invention relates to a loader weeder and an engineering loader, belonging to the technical field of weeding equipment. Background Art

[0002] Large weeding machines are suitable for open areas. In hardened areas such as parks or communities, weeds often grow in the gaps between floor tiles and on the edges of curbs. For this type of weeds, large weeding machines are easy to damage the floor tile structure, and soil-turning weeding is more likely to loosen the roadbed, which in turn pushes up the cost of repair. The existing technology is mainly based on manual weeding, but it faces many problems: on the one hand, manual weeding relies on intensive labor, workers need to bend over for a long time, the daily processing area is less than 50 square meters, and manual weeding is prone to residual roots, causing weeds to revive in a short period of time. Not only is the annual maintenance cost high, but it is also difficult to cope with labor shortages. On the other hand, traditional handheld power weeding devices are not adaptable enough, the blade width is fixed and lacks angle adjustment function, making it difficult to accurately cut into narrow brick joints. And forced operation is easy to scratch the glaze of floor tiles or leave blind spots at the root of curbs. When metal blades collide with concrete curbs, there is a safety hazard of flying debris.

[0003] In addition, chemical herbicides are prone to pollute the environment with rainwater and increase weed resistance, while flame weeding is limited by the risk of open flames and the heat resistance defects of materials such as plastic floor tiles. Existing technologies urgently need to break through the contradictions between accuracy, safety, environmental protection and adaptability to complex terrains, and develop solutions that are both efficient and low-loss, lightweight, and can cover hardened road micro-terrain.
