Description

Technical Field

[0001] The utility model relates to the technical field of forestry engineering, in particular to a weeder for forestry engineering. Background Art

[0002] As we all know, with the development of forestry engineering technology, weeding technology has gradually shifted from traditional manual weeding to mechanized and chemical weeding to cope with the weed challenges in large-scale forest management. Chemical weeding has been widely used due to its high efficiency and labor-saving characteristics, but attention should be paid to preventing environmental pollution and weed resistance. At the same time, mechanized weeding has also been increasingly valued due to its high efficiency and environmental protection potential.

[0003] After searching, the utility model patent with Chinese patent publication number CN220965613U discloses a weeder for forestry engineering, which includes a mounting base, a motor is fixedly connected to the top of the mounting base, a rotating disk is rotatably connected to the bottom of the mounting base, the rotating disk is fixedly connected to the output end of the motor, and a mounting plate is rotatably connected to the bottom of the rotating disk. The beneficial effect achieved by the utility model is that the motor on the mounting base starts to drive the rotating disk to rotate, and the rotating disk drives the mounting plate and the weeding blade to rotate for weeding. When the space to be weeded is relatively narrow, the positioning bolt on the adjusting disk can be loosened until it is separated from the originally combined positioning hole, and then the adjusting disk can be screwed. The adjusting disk will drive the four mounting plates and the weeding blade on the rotating disk to rotate at the same time through the connecting plate, so as to achieve the purpose of adjusting the extended length of the weeding blade, so that the weeding width is reduced when it rotates, which is convenient for weeding in narrow positions. After the adjustment is completed, the positioning bolt can be tightened until it is combined with the corresponding positioning hole.

[0004] Although the above technical solution solves the problem of weeding in a narrow location, in the above technical solution, only the roots of the grass are cut with a blade during weeding. In real life, some weeds can survive with only roots and absorb soil nutrients, which not only reduces the survival rate of trees, but also increases the workload for subsequent tree planting. In order to solve the above problems, a weeder for forestry engineering is needed. Utility Model Content
