Description

Technical Field

[0001] The present application relates to the technical field of brush cutters, and in particular to a forest tending and pruning brush cutter. Background Art

[0002] Brush cutters are used to sweep the edges of large areas of lawns or trim dead grass and shrubs. They are a type of forestry machinery used for woodland clearing, young forest cultivation, secondary forest transformation, forest cultivation and felling, etc., to cut shrubs, weeds, prune branches, cut small-diameter trees, cut bamboo, etc.

[0003] The existing patent (publication number: CN211630864U) discloses a brush cutter, including a connecting rod, a cutting device located at the head end of the connecting rod, and a power supply device located at the tail end of the connecting rod. The cutting device is connected to the power supply device in circuit communication. The connecting rod includes a coaxially arranged sleeve and a moving rod. One end of the moving rod extends into the interior of the sleeve and is slidably connected to the sleeve. The other end of the moving rod is located outside the sleeve. The sleeve connected to the moving rod is provided with at least two notches arranged along the axial direction of the sleeve, one end of which is open and the other end is closed. The sleeve connected to the moving rod forms a sheet structure matching the number of notches through the notches. The moving rod is slidably connected with a lock sleeve that moves in the direction of the sleeve to squeeze the sheet structure so that the sheet structure holds the moving rod tightly and fixes it. The lock sleeve is threadedly connected to the sleeve. The utility model has the advantage of being able to adjust the length of the brush cutter according to actual conditions.

[0004] The brush cutter mentioned in the above patent requires workers to carry a heavy driving device during operation, which puts a great burden on the workers' bodies over a long period of time. At the same time, when the brush cutter is in use, workers are also required to manually swing the operating lever to trim. This repetitive labor not only makes workers easily tired, but also may lead to low work efficiency. Long-term fatigue may also affect the workers' physical health. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a forest tending and pruning brush cutter, which has the advantages of simple operation, etc., and solves the problem that the existing brush cutters require workers to carry a heavy driving device during work, which puts a great burden on the workers' bodies over a long period of time. At the same time, when the brush cutter is in use, the workers are also required to manually swing the operating lever to trim. This repetitive labor not only makes the workers easily feel tired, but also may lead to low work efficiency. Long-term fatigue may also affect the workers' physical health.
