Description
Technical Field
[0001] The utility model belongs to the technical field related to lawn mowers, and particularly relates to a front-mounted lawn mower. Background Technique
[0002] The technology of weeding under fruit trees in orchards has always been an important research direction in the technical field of agricultural machinery. The methods of weeding under fruit trees in orchards mainly include manual weeding, tractor-mounted weeding machines, laying black plastic films, and spraying herbicides. With the rising labor cost, the cost of manual weeding is getting higher and higher, and it is time-consuming and laborious. For large-scale orchards and characteristic economic forest bases, manual weeding is not applicable due to high cost. Laying black plastic films can prevent the growth of some weeds, but the overall control effect is average, and large-area laying will also affect soil respiration and damage the beneficial bacteria in the soil. Spraying herbicides has an effect on some weeds, but long-term use of herbicides is not conducive to health, will pollute the soil, and is not environmentally friendly.
[0003] The tractor-mounted weeding machine is the main way of mechanized weeding under fruit trees in orchards at present. Its advantages lie in mechanized operation, liberating labor, being able to adapt to large-scale operation, and reducing planting costs. However, its disadvantages are that the tractor is relatively tall and large, requires a large row spacing for orchards and economic forests with relatively dense planting, the tractor will also break the hanging branches when moving forward, and the tractor is not easy to turn around, has a large turning radius, and a large open space needs to be reserved at the end of the field, wasting land. Therefore, we provide a front-mounted lawn mower to solve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a front-mounted lawn mower. Through the cooperation of driving wheels, driving wheels, driven wheels and supporting wheels with rubber tracks, it can freely walk and pass through under fruit trees in orchards. The crawler-type walking mechanism can achieve a U-turn in place, can adapt to various rugged terrains, sandy lands, soft wetlands, etc., and can effectively prevent sinking.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
