Description

Technical Field

[0001] This application relates to the field of mini excavator technology, and in particular to a toothed lawnmower for mini excavators. Background Technology

[0002] Mini excavators, also known as small excavators, are ideal for earthmoving projects in urban areas due to their compact size. Mini excavators are also widely used in lawn mowing operations because of their flexibility and adaptability. They can easily reach areas that are difficult for large machinery to access and carry out precise lawn mowing operations. During the lawn mowing process, the operator needs to frequently adjust the position and angle of the excavator to ensure the mowing effect.

[0003] In existing technologies, the traditional lawn mowing process can easily lead to injuries due to accidental contact, and the lack of protective measures reduces on-site safety. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the ease with which personnel can be injured by accidental contact during traditional lawn mowing, and the lack of adequate safety protection, which reduces on-site safety. Therefore, this invention proposes a toothed lawn mower for small excavators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A toothed lawnmower for a small excavator, comprising:

[0043] A protective mechanism is located on one side of the lawnmower body 1 to protect the lawnmower body 1;

[0044] A dust collection mechanism is located inside the dust collection box 7 and is used to collect dust from the inside of the lawnmower body 1.

[0045] The cleaning mechanism, located inside the dust collection box 7, is used to clean the filter screen.

[0046] In this embodiment, the protective mechanism includes a screw 4 rotatably mounted on one side of the lawnmower body 1, an L-shaped sealing cover 5 fixedly mounted on the outer surface of the screw 4, a motor mounted on the front side of the L-shaped sealing cover 5, the output shaft of the motor being fixedly connected to the screw 4, and a limit plate 6 fixedly mounted on the top of the lawnmower body 1, the limit plate 6 being located on the right side of the dust collection box 7.

[0047] In this embodiment, the mowing mechanism includes a groove disposed inside the mower body 1, a support plate 8 is fixedly installed on the inner wall of the groove, a drive motor 9 is disposed on the top of the support plate 8, and a turntable 10 is fixedly installed on the output shaft of the drive motor 9.

[0048] In this embodiment, a slider 11 is arranged on one side of the turntable 10 at a position off from the center. A support frame 12 is fixedly installed on one side of the slider 11. A cutting tooth 13 is fixedly installed on one side of the support frame 12. Telescopic rods are fixedly installed on both sides of the support frame 12.

[0049] In this embodiment, the vacuuming mechanism includes a motor 16 disposed inside the vacuuming box 7, a vacuuming pipe 14 fixedly installed at the bottom of the vacuuming box 7, a rotating shaft 17 fixedly installed on the output shaft of the motor 16, a fan blade 18 fixedly installed on one side of the rotating shaft 17, a filter screen located on the right side of the fan blade 18, and an exhaust port provided on the other side of the vacuuming box 7.

[0050] In this embodiment, the cleaning mechanism includes a first bevel gear 19 fixedly installed on the outer surface of the rotating shaft 17, the first bevel gear 19 meshing with a second bevel gear 20, a rotating rod 21 fixedly installed on the front side of the second bevel gear 20, and the rotating rod 21 being rotatably connected to the dust collection box 7, and a first sprocket 22 fixedly installed on the outer surface of the rotating rod 21.

[0051] In this embodiment, the first sprocket 22 is engaged with the chain 23, the chain 23 is engaged with the second sprocket 24, the second sprocket 24 is fixedly mounted with a rotating rod 25, and the rotating rod 25 is rotatably connected to the fixed box 15. The outer surface of the rotating rod 25 is fixedly mounted with a gear 26, the gear 26 is engaged with an annular rack 27, and the annular rack 27 is slidably connected to the fixed box 15.

[0052] In this embodiment, a moving block 28 is fixedly installed at the bottom of the annular rack 27, and the moving block 28 is slidably connected to the dust collection box 7. A cleaning brush 29 is fixedly installed on the other side of the moving block 28.

[0053] In this invention, during use, the handle 2 is pushed by hand, which moves the lawnmower body 1 as a whole. During mowing, the drive motor 9 is activated, and its output shaft rotates the turntable 10. The turntable 10 rotates the slider 11, which in turn rotates the support frame 12. The support frame 12 then rotates the cutting teeth 13 to cut the grass. The slider 11 and support frame 12 on the turntable 10 transmit the rotational motion to the cutting teeth 13, thus mowing the lawn or weeds in the field. During mowing, the motor 16 is activated, and its output shaft rotates the rotating shaft 17. The rotating shaft 17 drives the fan blades 18 to suck up dust and grass clippings through the suction pipe 14 into the suction box 7. The dust and grass clippings then exit through the exhaust port via a filter. This process effectively removes dust and grass clippings during mowing, preventing the inhalation of harmful substances from prolonged exposure to dusty environments and protecting the user's health. The system operates in a healthy manner. Simultaneously, the rotating shaft 17 drives the first bevel gear 19 to rotate, which in turn drives the second bevel gear 20 to rotate. The second bevel gear 20 then drives the rotating rod 21 to rotate, which in turn drives the first sprocket 22 to rotate. This is followed by the chain 23 driving the second sprocket 24 to rotate, which in turn drives the rotating rod 25 to rotate. The rotating rod 25 then drives the gear 26 to rotate. The rotation of the gear 26 causes the ring rack 27 to move, which in turn drives the moving block 28 to move downwards. The moving block 28 then drives the cleaning brush 29 to clean the surface of the filter screen, preventing the accumulation of dust and grass clippings, thus extending the filter screen's lifespan and improving filtration efficiency. When the grass cutting is complete, the motor is started, and the motor's output shaft drives the screw 4 to rotate. The screw 4 then drives the L-sealing cover 5 to close. During use, the L-sealing cover 5 protects the cutting teeth 13 from accidental contact due to fatigue, preventing injuries and improving on-site safety.
