Description

Technical Field

[0001] The utility model relates to the technical field of chassis devices, in particular to a chassis device for efficient operation on complex terrain. Background Art

[0002] In the current agricultural production process, field weeding operations occupy an important position. Traditional weeding methods, whether relying on manual handheld sprayers to spray chemicals or using mechanical equipment for large-scale spraying, mainly rely on herbicides. However, although this method can achieve the effect of weeding to a certain extent, its disadvantages are also obvious.

[0003] First, the use of herbicides will inevitably have a certain impact on the crops of the season. While killing weeds, these chemical agents may also have adverse effects on the growth and development of crops, and may even lead to reduced crop yields or reduced quality. Secondly, the residues left by herbicides in the soil are difficult to completely remove, which poses a potential threat to the growth environment of subsequent crops, especially for farmland that adopts intercropping and rotation models. This impact cannot be underestimated.

[0004] What is even more worrying is that these chemicals not only pollute the soil, but may also pose a health threat to workers engaged in agricultural production. Long-term exposure to herbicides may cause skin irritation, respiratory problems, and may even increase the risk of cancer. In addition, pesticide residues on harvested crops will directly affect the quality and safety of agricultural products, posing potential risks to consumers' health.

[0005] Because of this, laser weed control technology has gradually entered people's horizons in recent years and has received widespread attention as a new environmentally friendly weed control method. The working principle of laser weed control is to use laser beams to directly irradiate weeds, burn the leaves of weeds at high temperatures, and make them wither and die quickly, thereby achieving the effect of weed control. The biggest advantage of this method is that it does not require the use of any chemical agents, so it does not produce any noise and air pollution, and has minimal impact on soil and water sources.

[0006] The emergence of laser weeding technology has undoubtedly provided a more environmentally friendly and sustainable weeding method for agricultural production. However, we must also see that the existing laser weeding equipment still has some shortcomings. For example, the chassis wheelbase and chassis height of many equipment are fixed and cannot be adjusted according to the complexity of the terrain. This makes it difficult for the equipment to run smoothly on some rugged land, and the weeding effect will be greatly reduced. Summary of the invention

[0026] The two connecting rods 203 are connected via a hydraulic cylinder 202, one end of the hydraulic cylinder 202 is hinged to one connecting rod 203, and the other end is hinged to the other connecting rod 203. When the hydraulic cylinder 202 is extended or contracted, the two connecting rods 203 can be driven to rotate synchronously.

[0027] like Figure 5As shown, the lower end of the second pin shaft seat 204 is connected to the swivel leg 6 through the connecting sleeve 5, and a swing motor 7 is installed in the connecting sleeve 5.
