Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of weeding devices, and specifically relates to a weeding device for green onion planting. Background Art
[0002] As one of the important crops in China, the growth of weeds during the growth process of green onions has a significant negative impact on the growth and development of green onions. Weeds not only compete with green onions for water, nutrients and sunlight, but also may lead to the spread of pests and diseases. Therefore, timely and thorough weeding work is crucial for ensuring the growth of green onions and increasing yields. However, the existing weeding methods and devices have many deficiencies in practical applications and are difficult to meet the needs of modern agricultural production;
[0003] Currently, traditional weeding for green onion planting mainly relies on manual weeding or the use of chemical herbicides. Although manual weeding can ensure the thoroughness of weeding to a certain extent, it is time-consuming and laborious, with a high labor cost, and it is difficult to be widely promoted in large-scale planting. The use of chemical herbicides can reduce the labor intensity, but has a greater potential harm to the environment and crops, which may lead to a decline in the quality of green onions and soil pollution, not in line with the development trend of green agriculture;
[0004] In response to the above problems, some mechanized weeding devices have also been introduced in the market to improve the weeding efficiency through mechanical operations. However, these mechanical devices still have significant defects in actual use. On the one hand, the weeding effect of existing weeding devices is often not thorough enough. Due to the complex terrain in the field and the uneven plant heights, many weeding devices cannot always maintain the best contact state with the ground and plants during the operation process, resulting in weeds not being completely eradicated, leaving residual roots and rhizomes. These residual parts are easy to germinate again in a short time, thus increasing the difficulty and cost of subsequent weeding;
[0005] On the other hand, existing weeding devices usually only have the function of weeding and lack an effective function of collecting weeds. After the weeding operation is completed, the weeds shoveled up often scatter in the field and still need to rely on manual collection. This not only increases the workload, but also reduces the overall operation efficiency. Especially in a large-scale planting environment, the subsequent manual weed collection work has become a major bottleneck in the production process, further affecting the agricultural production efficiency;
[0006] Therefore, in view of these deficiencies in the prior art, the present utility model provides a weeding device for green onion planting. Summary of the Utility Model
