[0026] Please see Figure 1-6 This utility model provides a technical solution: a lawn mower for trimming lawns, including a base plate 1, a cutting mechanism 2 and a dust collection mechanism 3. The cutting mechanism 2 and the dust collection mechanism 3 are fixedly connected to the top of the base plate 1. The base plate 1 is rotatably connected to two sides of the base plate 1. Anti-slip strips 5 are fixedly connected to the outer surface of the wheels 4. The cutting mechanism 2 includes connecting through holes 21 opened on both sides of the base plate 1.
[0027] The specific setup and function of its cutting mechanism 2 and dust collection mechanism 3 will be explained below.
[0028] In this embodiment, the cutting mechanism 2 includes an electric height adjustment column 22 and a stone barrier 23, which is rotatably connected to the base plate 1 of the machine body.
[0029] A transmission assembly 24 is fixedly connected to the top of the connecting through hole 21. An electric height adjustment column 22 is threaded to the bottom of the transmission assembly 24. A cutting blade 25 is threaded to the bottom of the electric height adjustment column 22. The electric height adjustment column 22 and the cutting blade 25 are arranged at three equal intervals on both sides of the machine body base plate 1. The electric height adjustment column 22 is snapped into the inside of the connecting through hole 21. The cutting blade 25 is rotated and connected to the bottom of the machine body base plate 1 by the drive of the transmission assembly 24.
[0030] The effects achieved by the above components are as follows: the electric height adjustment column 22 can flexibly and accurately adjust the height of the cutting blade 25 according to the different height requirements of the lawn, so as to meet the diverse lawn mowing standards; the stone barrier 23 can effectively block stones, rocks and other debris on the lawn during the mowing process, preventing them from being splashed out under the high-speed rotation of the cutting blade 25, causing injury to the operator or damage to the surrounding environment and equipment.
[0031] Specifically, a connecting post 26 is fixedly connected to the outer surface of the stone barrier 23, and a rotating block 27 is fixedly connected to the outer surface of the connecting post 26. The rotating block 27 is rotatably connected to the outer surface of the machine body base plate 1, and the stone barrier 23 is rotatably connected to the outer surface of the machine body base plate 1 through the rotating block 27.
[0032] The effect achieved by the above components is as follows: through the rotating connection between the rotating block 27 and the base plate 1 of the machine body, the operator can flexibly adjust the angle of the stone barrier 23 according to the actual mowing environment. For example, when working at the edge of the lawn or in a sloping area, adjusting the stone barrier 23 to a suitable angle can provide more comprehensive protection against flying debris, greatly improving the safety during operation. In addition, the rotating block 27 is equipped with a damping device inside, so that the stone barrier 23 can be stably maintained after being adjusted to the required angle, and will not change the angle arbitrarily due to factors such as vibration of the lawnmower.
[0033] Specifically, the transmission assembly 24 includes a protective frame 241 fixedly connected to the top of the connecting through hole 21. A first motor 242 is fixedly connected inside the protective frame 241. A connecting plate 243 is fixedly connected to the output end of the first motor 242. Bolts 244 are threadedly connected to both sides of the connecting plate 243. An electric height adjustment column 22 is threadedly connected to the bottom of the connecting plate 243 through bolts 244.
[0034] The aforementioned components achieve the following effects: the protective frame 241 effectively protects the internal first motor 242, preventing grass clippings, dust, and other debris from entering and affecting its normal operation, thus extending its service life. After the first motor 242 starts, its output drives the connecting plate 243 to rotate at high speed. The electric height adjustment column 22, connected to the bottom of the connecting plate 243 by bolts 244, also rotates, thereby driving the cutting blade 25 to rotate for mowing. The use of bolts 244 to connect the electric height adjustment column 22 and the connecting plate 243 facilitates quick disassembly and installation when the electric height adjustment column 22 malfunctions or when different specifications of parts need to be replaced.
[0035] Specifically, a support plate 28 is snapped onto the outer surface of the electric height adjustment column 22 and the cutting blade 25, and the top of the support plate 28 is fixedly connected to the bottom of the machine body base plate 1.
[0036] The aforementioned components achieve the following effects: the support plate 28 provides additional support for the electric height adjustment column 22 and the cutting blade 25, reduces vibration caused by factors such as the high-speed rotation of the cutting blade 25 and uneven lawn during mowing, and enhances the stability of the electric height adjustment column 22 and the cutting blade 25 during operation. This not only helps to improve the accuracy and quality of the cutting operation, but also effectively extends the service life of the electric height adjustment column 22 and the cutting blade 25.
[0037] Specifically, the dust collection mechanism 3 includes a connecting frame 31 located on one side of the bottom of the base plate 1 of the machine body. A second motor 32 is fixedly connected inside the connecting frame 31, and a suction fan 33 is fixedly connected to the output end of the second motor 32.
[0038] The effect achieved by the above components is as follows: after the second motor 32 is started, it drives the suction fan 33 to rotate at high speed, forming a strong negative pressure suction force in the dust collection mechanism 3. This suction force can quickly suck the grass clippings cut by the cutter 25 into the collection system, preventing grass clippings from scattering and accumulating on the lawn, maintaining the cleanliness of the lawn, and also reducing the amount of manual grass clipping cleaning work afterwards.
[0039] Specifically, the dust collection mechanism 3 includes a collection port 34 located on the other side of the bottom of the base plate 1. The bottom of the collection port 34 is open and fixedly connected to the bottom of the base plate 1. A collection tube 35 is fixedly connected to the top of the collection port 34, and a collection frame 36 is snapped onto the outer surface of the collection tube 35.
[0040] The effects achieved by the above components are as follows: the opening design of the collection port 34 facilitates the smooth entry of grass clippings into the collection system under the suction force generated by the suction fan 33; the collection tube 35 transfers the grass clippings sucked in from the collection port 34 to the collection frame 36; the collection frame 36 is used to centrally store grass clippings; the snap-fit connection method allows the collection frame 36 to be easily and quickly removed from the collection tube 35 when grass clippings need to be cleaned, making the operation simple and efficient.
[0041] Specifically, the outer surfaces of the collection frame 36 and the collection pipe 35 are fitted with connecting clamps 37, and connecting parts 38 are threaded to both sides of the connecting clamps 37. The connecting clamps 37 and the collection pipe 35 are arranged at three equal intervals on the outer surface of the collection frame 36. A ventilation mesh plate 39 is fixedly connected to the bottom of the collection frame 36, and limiting parts 310 are threaded to both sides of the collection frame 36. The collection frame 36 is threaded to the top of the machine body base plate 1 through the limiting parts 310.
[0042] The effects achieved by the above components are as follows: the connecting clamp 37 and the connecting piece 38 fit together tightly to firmly connect the collection frame 36 and the collection pipe 35 together, preventing the connection from loosening and causing grass clipping leakage during the grass clipping suction process. The connecting clamp 37 and the collection pipe 35 are set at three equal intervals on the outer surface of the collection frame 36 to make the connection more stable and reliable. The presence of the ventilation mesh plate 39 can balance the air pressure inside the collection frame 36 on the one hand, ensuring that the suction fan 33 continuously and stably generates suction, and on the other hand, prevent grass clipping from leaking out from the bottom of the collection frame 36.
[0043] Working principle: When the lawnmower starts working, the operator pushes the lawnmower forward, and the walking wheels 4 roll on the lawn. The anti-slip strips 5 on their outer surface provide sufficient friction to ensure that the lawnmower moves stably and is not easy to slip even on wet or sloping lawns. At the same time, the first motor 242 is started, which drives the connecting plate 243 to rotate, thereby causing the electric height adjustment column 22 and the cutting blade 25 connected to the connecting plate 243 to rotate at high speed to cut the lawn.
[0044] Operators can precisely adjust the height of the cutting blade 25 by controlling the extension and retraction of the electric height adjustment column 22 according to the actual height requirements of the lawn. During the cutting process, the stone barrier 23 can block stones and other debris from flying on the lawn. If special terrain is encountered or the protective angle needs to be adjusted, the angle of the stone barrier 23 can be flexibly adjusted by rotating the block 27.
[0045] At the same time, the second motor 32 is started, which drives the suction fan 33 to run at high speed, creating a negative pressure in the dust collection mechanism 3. The cut grass clippings are sucked into the collection pipe 35 from the collection port 34 by the suction force generated by the suction fan 33, and finally enter the collection frame 36 for storage. The collection frame 36 is securely installed on the machine body by the connecting clamp 37, the connecting piece 38 and the limiting piece 310. The ventilation mesh plate 39 at the bottom ensures the balance of air pressure and the stability of suction during the dust collection process. When the grass clippings in the collection frame 36 are full, the collection frame 36 can be easily removed for cleaning by disassembling the connecting clamp 37 and the limiting piece 310. After cleaning, it can be reinstalled to continue the grass cutting and grass clipping collection operation.
