Description

Technical Field

[0001] This utility model relates to the field of weeding machine technology, and more specifically, to a weeding device for forestry engineering. Background Technology

[0002] Forestry engineering weeding devices are indispensable tools in forest management and ecological maintenance. They are mainly used to remove weeds, shrubs and invasive plants to promote tree growth, prevent fires and maintain ecological balance. Existing technologies focus on mechanical structure innovation, taking into account both efficiency and adaptability.

[0003] The handle design and engine mounting method of a lawnmower directly affect the operator's comfort and equipment maintenance efficiency. These two major pain points have long restricted the improvement of efficiency in forestry and landscaping operations. For users with large differences in height, it is impossible to accurately match the ergonomic posture, resulting in a forward tilt angle of more than 15° during operation, which makes the user very tired. At the same time, the engine is usually connected to the frame with bolts, which is not convenient for the engine to be installed and disassembled, and the maintenance time is too long, affecting the efficiency of use.

[0029] Please see Figures 1-5A weeding device for forestry engineering includes a weeder 1, which includes a frame 2. The frame 2 has a mounting device and an engine 3. A connecting plate 4 and a handle 5 are rotatably mounted on the frame 2. One end of the connecting plate 4 is hinged to the frame 2, and the other end has a limiting sleeve 6. The limiting sleeve 6 has a limiting block 7, a limiting rod 8, and a limiting head 9. The frame 2 has multiple limiting holes 10, and limiting grooves 11 connect the limiting holes 10. The mounting device includes a mounting sleeve 12 and a mounting rod 13. The mounting rod 13 is located at the bottom of the engine 3, and the mounting sleeve 12 is located at the bottom of the frame 2. A snap-fit ​​block 14 is provided via a torsion spring hinge. A snap-fit ​​groove 15 that mates with the snap-fit ​​block 14 is provided on the mounting rod 13. Extrusion plates 16 are provided on both sides of the mounting sleeve 12. A fixing device is provided between the extrusion plates 16 and the mounting sleeve 12. A limiting protrusion 17 is provided at one end of the limiting block 7 inside the limiting sleeve 6. A limiting spring 18 is provided between the limiting protrusion 17 and the limiting sleeve 6. A drive shaft 27 is provided on the frame 2. A drive disc 28 is provided on the drive shaft 27. A blade 29 is provided axially on the drive disc 28. A pulley 30 is connected to the output end of the engine 3 and the drive shaft 27. A transmission belt 31 is provided between the pulleys 30.

[0030] In this embodiment, during use, the angle of the handle 5 is adjusted as needed. The limit handle 5 is pressed simultaneously on both sides of the handle 5. The limit handle 5 drives the limit rod 8 and the limit block 7 to move inward to the limit sleeve 6 and squeezes the limit spring 18. The connecting plate 4 and the handle 5 are rotated, and the limit rod 8 moves between the limit grooves 11. After adjustment, the limit block 7 and the limit rod 8 move outward under the action of the limit spring 18, so that the limit block 7 is engaged with the limit hole 10, thereby fixing the position of the connecting plate 4 and the frame 2. The movement position of the limit block 7 and the limit rod 8 is limited by the limit protrusion 17. The engine 3 drives the drive shaft 27, the drive disc 28 and the blade 29 to rotate through the cooperation of the pulley 30 and the transmission belt 31. The blade 29 is rotated to cut and remove grass. The frame 2 is also equipped with a protective box covering the drive disc 28 and the blade 29, as well as a protective box protecting the pulley 30 and the transmission belt 31, which improves the stability of the weeder 1.

[0031] Please see Figures 4-5 As one embodiment of the installation device: the installation sleeve 12 is provided with an installation groove 19, and a connecting plate 20 is provided between the two extrusion plates 16 in the installation groove 19. The fixing device includes a fixing rod 21, a fixing plate 22 and an insertion rod 23 are rotatably provided on the fixing rod 21, and an insertion hole 24 is provided on both the connecting plate 20 and the installation sleeve 12. A fixing piece 25 is provided on the fixing rod 21, and a fixing spring 26 is provided between the fixing piece 25 and the fixing plate 22.

[0032] More specifically, in the prior art, the bottom of the engine 3 is mounted on the frame 2 via rubber pads, etc. The mounting rod 13 at the bottom of the engine 3 is inserted into the mounting sleeve 12 of the frame 2. The fixing plate 22 and the insertion rod 23 are pulled outwards, causing the fixing plate 22 to compress the fixing spring 26. The insertion rod 23 leaves the mounting sleeve 12 and the insertion hole 24 of the connecting plate 20. The connecting plate 20 and the pressing plate 16 move upwards, pressing the snap-fit ​​block 14 upwards through the pressing plate 16. The snap-fit ​​block 14 is fan-shaped and extends into the snap-fit ​​groove 15 to fix the position of the mounting rod 13. Then... Continue to flip the fixing plate 22 so that the insertion rod 23 corresponds to the insertion hole 24. Insert the insertion rod 23 into the insertion hole 24 under the elastic force of the fixing spring 26. Continue to fix the position of the connecting plate 20 and the mounting sleeve 12, and then fix the position of the pressing plate 16 and the snap-fit ​​block 14, and then fix the position of the engine 3. When removing the mounting rod 13, pull the fixing plate 22 and the insertion rod 23 outward, move the pressing plate 16 downward, and the snap-fit ​​block 14 rotates outward and resets under the elastic force of the torsion spring. The snap-fit ​​block 14 disengages from the snap-fit ​​groove 15, and the mounting rod 13 can be removed.

[0033] In summary, during the use or operation of the overall equipment: When in use, adjust the angle of handle 5 as needed. Press the limit handle 5 simultaneously on both sides of handle 5. The limit handle 5 drives the limit rod 8 and limit block 7 to move inward towards the limit sleeve 6, compressing the limit spring 18. Rotate the connecting plate 4 and handle 5, moving the limit rod 8 between the limit grooves 11. After adjustment, the limit block 7 and limit rod 8 move outward under the action of the limit spring 18, causing the limit block 7 to engage with the limit hole 10, thereby... The positions of the connecting plate 4 and the frame 2 are fixed. The movement positions of the limiting block 7 and the limiting rod 8 are limited by the limiting protrusion 17. The engine 3 drives the drive shaft 27, drive disc 28 and blade 29 to rotate through the cooperation of pulley 30 and transmission belt 31. The blade 29 rotates to cut and remove grass. The frame 2 is also equipped with a protective box covering the drive disc 28 and blade 29, as well as a protective box protecting the pulley 30 and transmission belt 31, which improves the stability of the weeder 1.

[0034] In the prior art, the bottom of the engine 3 is mounted on the frame 2 via rubber pads, etc. The mounting rod 13 at the bottom of the engine 3 is inserted into the mounting sleeve 12 of the frame 2. The fixing plate 22 and the insertion rod 23 are pulled outward, the fixing plate 22 compresses the fixing spring 26, and the insertion rod 23 leaves the insertion hole 24 of the mounting sleeve 12 and the connecting plate 20. The connecting plate 20 and the pressing plate 16 move upward, and the pressing plate 16 presses the snap-fit ​​block 14 upward. The snap-fit ​​block 14 is fan-shaped and extends into the snap-fit ​​groove 15 to fix the position of the mounting rod 13. Then, the rotation continues. The fixing plate 22 is used to align the insertion rod 23 with the insertion hole 24. The insertion rod 23 is inserted into the insertion hole 24 under the elastic force of the fixing spring 26. The positions of the connecting plate 20 and the mounting sleeve 12 are then fixed, which in turn fixes the positions of the pressing plate 16 and the snap-fit ​​block 14, and thus fixes the position of the engine 3. When removing the mounting rod 13, the fixing plate 22 and the insertion rod 23 are pulled outward, the pressing plate 16 is moved downward, and the snap-fit ​​block 14 rotates outward and resets under the elastic force of the torsion spring. The snap-fit ​​block 14 disengages from the snap-fit ​​groove 15, and the mounting rod 13 can then be removed.
