Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, in particular to a flame weeder with a targeting function. Background Art

[0002] In agricultural production practice, weeds in the field are a significant threat to crop growth. Weeds compete with crops for nutrients, water and light resources, and also create conditions for the breeding and spread of pests and diseases, thus having a negative impact on the healthy growth of crops. It can be seen that weeding operations occupy a key position in the agricultural production process, which is directly related to the growth trend, yield level and quality of crops.

[0003] At present, within the scope of agricultural machinery and equipment technology, herbicide spraying devices have been widely used in agricultural production. The principle is to spray chemical herbicides on farmland to control the growth of weeds. This type of equipment plays an important role in large-scale farmland management, which can effectively reduce manpower input and significantly improve weed control efficiency. However, traditional herbicide spraying devices have obvious defects. It is often difficult to achieve the goal of precise spraying. Usually, the herbicide is evenly distributed throughout the field, and the area where the weeds are located cannot be accurately locked. This situation not only causes a large amount of herbicide waste, but also during the spraying process, the liquid medicine drifts due to changes in wind and climatic conditions, which may cause damage to crops. In addition, long-term use of chemical herbicides will gradually make weeds resistant to drugs, resulting in a continuous decrease in the weed control effect. In order to maintain the weed control effect, more powerful chemical agents need to be used, thus forming a vicious circle. At the same time, most herbicides are chemical synthetic substances, which may evaporate into the air during use, or penetrate into the soil and water sources with water, posing a potential pollution threat to the environment.

[0004] For existing flame weeders, their design usually adopts a fixed-width nozzle, which cannot be flexibly adjusted according to the width of different ridges. In view of the differences in planting row spacing and ridge width of different crops, the use of fixed-width nozzles is prone to uneven flame coverage, which will not only weaken the weeding effect, but also may cause weeds in some areas to be unable to be completely removed. In addition, existing flame weeders lack precise targeted control capabilities in flame spraying, and the flames can easily spread to neighboring crops, especially in the seedling stage of crops. Since the seedlings have poor tolerance to high temperatures, the high temperature of the flames can easily burn them, resulting in crop damage or delayed growth. Especially in an environment with high wind speeds, the flames are offset by the wind, further increasing the risk of damage to crops.

[0005] In view of this, the present invention proposes a flame targeted weeding technology equipment, which is specially used for precision weeding and weed control in agricultural production, aiming to overcome the problems existing in existing weeding technology, improve weeding efficiency and accuracy, and reduce adverse effects on crops and the environment. Summary of the invention

[0006] The purpose of the present invention is to provide a flame weeder with a targeting function in response to the problems existing in the prior art.
