Referring to fig. 1, the transmission structure includes a transmission case 2, a driving shaft 22 at one side of the transmission case 2 is fixedly sleeved on a driving wheel 21, the driving wheel 21 is directly in transmission connection with a driving device on the existing market, for example, a driving motor of a mower on the existing market, the driving motor is connected with a driving wheel, the driving wheel is in transmission connection with the driving wheel 21 in the present application, and the transmission connection mode can be chain transmission or belt transmission. Referring to fig. 2, the bottom of the transmission case 2 is connected with a transmission shaft 23, and the transmission shaft 23 is connected with the cutting knife 3. In the working process, the driving wheel 21 is driven by the driving device to rotate, and the transmission shaft 23 rotates under the action of the transmission case 2 to drive the cutting knife 3 to rotate and carry out mowing work. The gear box 2 is prior art and can be purchased directly from the market by a person skilled in the art.

Preferably, the gearbox 2 is a high-speed gearbox. Preferably, the other side of transmission case 2 is equipped with idle stop lever 24, and after the work of mowing stopped, can make cutting knife 3 and transmission case 2 stop work through idle stop lever 24, avoids transmission case 2 long-time work and generate heat, reduces life, can avoid the cutting knife 3 to work the incident problem that brings always simultaneously.

Preferably, the driving wheel 21 is provided with a guard plate to prevent grass from winding around the driving wheel 21 during mowing and affecting the driving force of the driving wheel 21.

Preferably, the mounting base 11 is further provided with a connecting structure for connecting a driving device, the connecting structure includes a connecting rod 4 fixedly connected to the mounting base 11, and the connecting rod 4 is provided with a plurality of fixing holes 41.

Referring to fig. 1, the walking structure includes a rotating sleeve 5 fixed at the front end of the mounting seat 11, a rotating rod 51 is sleeved inside the rotating sleeve 5, auxiliary rods 52 are respectively arranged at two ends of the rotating rod 51, and a walking wheel 53 is rotatably connected to each auxiliary rod 52.

In the use process, because one end of the whole mower assembly is connected to the driving device through the connecting rod 4, the driving device in the prior art is a trolley type, and therefore, the mower assembly can be pushed and walk through the driving device as long as the walking wheels 53 are arranged at the front end of the mounting seat 11.

The height adjusting structure comprises an adjusting plate 6 fixedly sleeved on the rotating rod 51, the adjusting plate 6 is fixedly connected with one end of an adjusting shaft 61, the middle part of the other end of the adjusting shaft 61 is movably sleeved with a positioning sleeve 62, the positioning sleeve 62 is fixedly connected to the housing 1 through a positioning block 621, and the position of the adjusting shaft 61 is fixed through the action of the positioning sleeve 62; the head of the other end of the adjusting shaft 61 is sleeved with an adjusting head 63 in a threaded manner.

During operation, since the position of the adjusting shaft 61 is fixed, when the adjusting head 63 is rotated, the adjusting shaft 61 can only move in the b direction or the c direction in the adjusting head 63. When the adjusting shaft 61 moves towards the direction b, the adjusting plate 6 is rotated in the direction f by the pulling force of the adjusting shaft 61, meanwhile, the auxiliary rod 52 is also rotated in the direction f, the auxiliary rod 52 is inclined by the rotation, the walking wheel 53 is moved upwards relative to the original position by the inclination action, and the walking wheel 53 is naturally fallen onto the ground; conversely, when the adjustment shaft 61 is moved in the direction c, the traveling wheels 53 are moved downward with respect to their original positions.

Referring to a diagram A in FIG. 4, when the auxiliary rod 52 is vertical, the height of the housing 1 and the cutter 3 from the ground is the largest, and the height of grass left on the ground is the highest after the grass is cut; referring to fig. 4B, when the auxiliary rod 52 is inclined, the travelling wheels 53 fall on the ground, so that the height of the housing 1 and the cutter 3 from the ground is reduced, and the height of grass left on the ground is reduced. Therefore, the grass cutting height of the grass cutter assembly can be adjusted through the height adjusting structure.

Preferably, the adjusting head 63 is provided with a handle 64, which facilitates the worker to rotate the adjusting head 63.

Preferably, the middle part of the other end of the adjusting shaft 61 is further fixedly sleeved with a limiting ring 65, and the part of the adjusting shaft 61, which is located between the limiting ring 65 and the positioning sleeve 62, is sleeved with an elastic member 66. In the present invention, the elastic member 66 is a spring.
