[0024] like Figures 1 to 8 As shown, the utility model provides a forestry handheld lawn weeder, comprising a hollow cylinder 1, characterized in that: a rotating shaft 2 is rotatably connected inside the hollow cylinder 1, a suction fan 3 is fixedly installed in the middle of the rotating shaft 2, an arc-shaped slide groove 4 is provided on the outer wall of one end of the rotating shaft 2 away from the suction fan 3, sliding columns 5 are slidably connected to the inner sides of the arc-shaped slide groove 4, one end of the sliding column 5 is fixedly connected to a connecting column 6, a sliding ring 7 is fixedly connected to the bottom of the two connecting columns 6, a disk 8 with a hollow interior in the middle is fixedly connected to the bottom of the sliding ring 7, a plurality of cleaning columns 9 are fixedly connected to the bottom of the disk 8, a plurality of through holes 10 are provided on the outer surface of the disk 8, a suction hole 11 corresponding to the cleaning column 9 is provided at the bottom of the hollow cylinder 1, an air outlet 20 is provided at the top of the hollow cylinder 1, and an air outlet pipe 21 with a plurality of air outlet holes 22 on the top is fixedly connected above the air outlet 20.

[0025] A rotating shaft 2 is provided to be rotatably connected to the interior of the hollow cylinder 1, and a suction fan 3 is fixedly installed in the middle of the rotating shaft 2. When the driving rotating shaft 2 starts to rotate, the suction fan 3 will be synchronously driven to rotate inside the hollow cylinder 1 to achieve a dust suction effect. The dust in the working area is filtered and sucked into the interior of the hollow cylinder 1 through the suction hole 11, and then further filtered into the air through the outlet hole in the outlet pipe 21. While the rotating shaft 2 is rotating, the sliding column 5 slidably connected to the inside of the arc-shaped slide groove 4 will slide back and forth, thereby driving the sliding ring 7 and the disc 8 to reciprocate up and down. The cleaning column 9 connected to the bottom of the disc 8 can repeatedly clean the suction hole 11 at the bottom of the hollow cylinder up and down, which can avoid clogging of the suction hole 11 while suctioning dust, thereby further improving its dust suction efficiency.

[0026] The bottom of the disc 8 is overlapped on one end of the travel spring 12 , and the other end of the travel spring 12 is fixedly connected to the bottom of the hollow cylinder 1 .

[0027] One end of the travel spring 12 is overlapped on the bottom of the disc 8, and the other end is fixed to the bottom of the hollow cylinder 1, so that the disc is provided with bearing force and the movement trajectory of the disc is effectively limited.

[0028] Among them, three fixed seats 13 are fixedly arranged on the bottom circumference of the hollow cylinder 1, and the middle interior of the three fixed seats 13 is provided with a travel hole 14, and the interior of the travel hole 14 is provided with a travel groove 15 on both sides, and a base 17 is slidably arranged inside the travel groove 15. A section of a hard spring 16 is welded on the top of the base 17, and the other end of the hard spring 16 is welded to the interior of the fixed seat 13. The interior of the base 17 is fixedly connected to a wheel axle 18, and the exterior of the wheel axle 18 is rotatably connected to a roller 19.

[0029] By arranging the fixing seat 13 at the bottom of the hollow cylinder, when the device travels on a rough road, the base 17 inside the fixing seat 13 will compress the hard spring 16 to slide inside the travel groove 15, thereby achieving a shock-absorbing effect.

[0030] The outer diameter of the cleaning column 9 is smaller than the inner diameter of the suction hole 11 , and the outer diameter of the through hole 10 is smaller than the inner diameter of the cleaning column 9 .

[0031] By setting the outer diameters of the cleaning columns 9 to be smaller than the inner diameters of the suction holes 11 and the outer diameters of the through holes 10 to be smaller than the inner diameters of the cleaning columns 9 , the cleaning columns 9 will not be blocked during the cleaning process.

[0032] Among them, an arc groove 23 is opened in the middle of the side wall of the hollow cylinder 1, and an arc block 24 is movably connected inside the arc groove 23. The top and bottom of the arc block 24 are fixedly connected to connecting blocks 26. Bolts 27 are screwed inside the two connecting blocks 26. A handle 25 is fixedly connected to the middle of the outer wall of the arc block 24.

[0033] The side wall of the hollow cylinder 1 is provided with an arc groove 23. When cleaning, the bolts threaded inside the connecting block 26 can be loosened, and the handle 25 can be pulled to expose the arc groove 23 and then the inside can be cleaned. The structure is simple and convenient for cleaning.

[0034] The top of the hollow cylinder 1 is provided with a working rod 28 which passes through the top and is rotatably connected to the rotating shaft 2 , and a cutter head 29 is fixedly connected to the end of the rotating shaft 2 .

[0035] By connecting the cutter head 29 to the rotating shaft 2, the rotating shaft 2 can be driven to clean weeds and remove dust and blockages when the device is running.

[0036] The working principle and use process of this utility model:

[0037] First, when the working rod 28 drives the rotating shaft 2 to rotate and the cutter head 29 rotates to clean the weeds, it will simultaneously drive the suction fan 3 to rotate inside the hollow cylinder 1 to achieve dust suction. The dust in the working area is filtered and sucked into the interior of the hollow cylinder 1 through the suction hole 11, and then further filtered into the air through the outlet hole 22 in the outlet pipe 21. While the rotating shaft 2 is rotating, the sliding column 5 slidingly connected inside the arc-shaped slide groove 4 opened therein will slide back and forth, thereby driving the connecting column 6 to reciprocate, and then driving the sliding ring 7 and the disc 8 to reciprocate up and down. The cleaning column 9 connected to the bottom of the disc 8 can repeatedly clean the suction hole 11 at the bottom of the hollow cylinder 1 up and down, and can avoid clogging of the suction hole 11 while suctioning dust, thereby further improving its dust suction efficiency. When the equipment is traveling on a rugged road, the base 17 inside the fixed seat 13 will compress the hard spring 16 to slide inside the travel groove 15, thereby achieving a shock absorbing effect.
