[0002] As we all know, a lawn mower is a mechanical equipment used to trim lawns, vegetation, etc. It is widely used in garden landscape maintenance, agricultural production and other fields. Traditional mowing methods mostly rely on manual use of tools such as sickles, which are inefficient and labor-intensive. With the development of technology, lawn mowers came into being. They can quickly cut weeds, greatly improve work efficiency, and save labor costs. According to the power source, they can be divided into fuel, electric, and manual types. Different types are suitable for different scenarios and play an indispensable role in modern greening maintenance.

[0003] CN107624368B discloses a lawn mower suitable for trimming trimmed objects on a lawn, the lawn mower comprising: a lawn mower body; and a support structure installed in the lawn mower body; and the support structure can extend relative to the lawn mower body or retract the lawn mower body; the support structure can extend relative to the lawn mower body from the bottom of the lawn mower body to support the lawn mower body or part of the lawn mower body from the lawn. After the support structure of the lawn mower of this invention extends from the bottom of the lawn mower body, the lawn mower body can be supported from the lawn, so that there is a certain distance between the bottom of the lawn mower body and the lawn, thereby avoiding contact friction between the bottom of the lawn mower body and the lawn, and further preventing the bottom of the lawn mower body from wearing out the lawn.

[0004] When mowing irregular grass at a certain height, an automatic lifting structure of the cutting table of the lawn mower is used to adapt to the height of the irregular grass. The problems with the prior art are: due to the lack of an adaptive mowing structure for uneven and irregular grass, it is impossible to adaptively adjust the height according to the uneven and irregular grass, which reduces the flexibility when mowing the uneven and irregular grass, and there is a lack of a structure for air-drying the grass clippings collected after cutting, so the grass clippings cannot be air-dried to reduce space occupancy, which reduces the stability when recycling the grass clippings.

[0048] Among them, the introduction component 11 includes a guide shell 111, a guide frame 112 and a handlebar 113. The guide frame 112 is fixedly connected to the front side of the inner side of the guide shell 111, and the handlebar 113 is fixedly connected to the top of the guide shell 111. By setting the introduction component 11, the guide shell 111 can cooperate with the guide frame 112 and the handlebar 113. The drying component 12 and the adjustment mechanism 2 are supported and limited by the guide shell 111 and the guide frame 112, which can increase the stability of the overall structure. The grass clippings and air can be concentrated through the guide frame 112 and guided into the drying component 12 through the guide shell 111. The handlebar 113 can facilitate the user to guide the overall movement of the collection mechanism 1 and the adjustment mechanism 2.

[0049] Among them, the drying component 12 includes a drainage frame 121, a storage bin 122 and an interception net 123. The drainage frame 121 is clamped on the rear side of the guide frame 112, the storage bin 122 is fixedly connected to the top of the drainage frame 121, and the interception net 123 is fixedly connected to the rear side of the inner side of the storage bin 122. By setting the drying component 12, the drainage frame 121 can cooperate with the storage bin 122 and the interception net 123. The air and grass clippings introduced into the guide shell 111 can be further guided by the drainage frame 121, and the grass clippings can be guided into the storage bin 122 for storage. The interception net 123 can intercept the grass clippings and let the air flow out, thereby intercepting and storing the grass clippings without affecting the air circulation.

When the adjusting mechanism 2 is mowing the grass, the exhaust fan 132 will extract the air from the guide shell 111 and the drainage frame 121, so that the air can drive the grass clippings generated by mowing to flow into the storage bin 122 along the guide frame 112, and the grass clippings will be intercepted by the interception net 123, and then the moisture in the grass clippings will be carried out together with the passing air. When the grass clippings need to be cleaned after mowing, the positioning plate 133 and the assembly frame 131 are pulled outward, and the assembly frame 131 will drive the drainage frame 121, the storage bin 122 and the interception net 123 to move out together, and the grass clippings in the storage bin 122 can be cleared.

By setting the transmission assembly 26, the electric half gear 261 can cooperate with the double-sided tooth frame 262 and the transmission tooth plate 263, and the electric half gear 261 drives the double-sided tooth frame 262 to perform left and right reciprocating motion, so that the double-sided tooth frame 262 can drive the transmission tooth plate 263 to perform reciprocating motion together, and the transmission tooth plate 263 drives the transmission half gear 241 to rotate back and forth, thereby providing kinetic energy for the swing required for cutting by the cutting blade 243.

[0060] The working principle of this embodiment is as follows: first, start the height adjustment hydraulic rod 232, which will push the height adjustment triangular wheel 233 downward, thereby driving the height adjustment plate 231 to push the entire structure of the adjustment mechanism 2 upward until the height of the entire structure of the adjustment mechanism 2 moves to the required grass cutting height, then start the adaptation hydraulic rod 252, and let the adaptation hydraulic rod 252 push the adaptation triangular wheel 253 to push the adaptation connecting seat 251 to the required height. When grass cutting is required, the user pushes the collecting mechanism 1 to move the adjusting mechanism 2 on the grass, and the adaptation triangular wheel 253 and the height adjustment triangular wheel 233 will move along the grass. When the adaptation triangular wheel 253 moves to the uneven terrain, the adaptation triangular wheel 253 will The adaptive hydraulic rod 252 and the adaptive connecting seat 251 will be driven by the terrain to adjust the position of the cutting and combing plate 223, and then the combing rotating plate 222 will change the angle of the cutting and combing plate 223 with the base rotating rod 221 as the center, so that the cutting and combing plate 223 drives the cutting blade 243 to move together, thereby changing the height of grass cutting, and then the electric half gear 261 will drive the double-sided tooth frame 262 to move back and forth, and the transmission tooth plate 263 will drive the transmission half gear 241 to rotate with the double-sided tooth frame 262, and when the transmission half gear 241 rotates back and forth, it will drive the cutting rotating plate 242 to swing the cutting blade 243 back and forth, thereby cutting the grass that it touches.
