Description

Technical Field

[0001] The present application relates to the field of weeding devices, and in particular to a weeder. Background Art

[0002] Commonly used weed control methods include chemical weed control, manual weed control and weed control with a weeder. Chemical weed control has the problem of causing environmental pollution and destroying the soil microbial environment, while manual weed control has the problem of low weed control efficiency and high labor costs. The use of a weed control machine greatly improves the weed control efficiency and reduces the impact on the environment. Therefore, weeders are widely used in weed control work in garden maintenance.

[0003] However, the weeding blade of the lawn mower can only remove the weeds above the ground surface, and the weeding blade cannot destroy the weed root system, which causes the weeds to grow quickly after weeding is completed, requiring workers to weed frequently, increasing the labor burden of the workers. In addition, the lawn mower cannot effectively clean the pests, insect eggs, plant pathogens and viruses, and weed seeds in the soil, which is not conducive to the growth of landscape crops, and further affects the overall effect of the later landscape. Moreover, the large amount of weeds removed by the lawn mower can only be treated as green waste and cannot be effectively utilized, resulting in a waste of resources.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing weeders have the problems of poor long-term weeding effect, inability to remove harmful factors that harm the growth of landscape crops, and inability to effectively utilize the weeds that have been removed.
