[0002] The slopes of hills are generally gentle, broken and without a certain direction. Generally, there are no obvious veins and the top is round. They are the product of long-term erosion of mountains. As the population increases, the area of arable land required is also increasing. Hills belong to a type of arable land.
[0003] In the treatment of hills, it is necessary to use a land finishing machine to till the hilly ground. When the current land finishing machine is used for tilling, the rotary tilling and crushing wheel is generally installed on the rear end of a mobile device such as a four-wheeled agricultural machine, and the mobile device drives the rotary tilling and crushing wheel to move the soil. However, due to the uneven terrain of the hills, when the crushing wheel crushes the soil, the terrain in a concave position cannot be fully tilled. Therefore, a land finishing machine for hills is proposed. Utility Model Content
[0004] In view of the uneven terrain of the existing hills, which causes the problem that when the crushing wheel crushes the soil, the terrain in the concave position cannot be fully tilled, the utility model is proposed.

[0006] Preferably, one end of the mounting mainboard is fixedly connected to the motor, and one end of the main shaft is fixedly connected to the output end of the motor.
[0007] Preferably, a mudguard is provided above the main shaft, the control panel and the crushing blade wheel are located below the mudguard, and the mudguard is elastically rotatably connected to the mounting main board.
[0008] Preferably, a contact rod is installed on one side of the control panel close to the fender, and the thickness of the contact rod is smaller than the thickness of the control panel.

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0025] Reference Figure 1-6 , is an embodiment of the utility model, which provides a hilly land trimming machine, the hilly land trimming machine includes an installation mainboard 1, the installation mainboard 1 is connected to the mobile machine, one side of the installation mainboard 1 is rotatably connected with a main shaft 4, one end of the installation mainboard 1 is fixedly connected with a motor 10, one end of the main shaft 4 is fixedly connected with the output end of the motor 10, the motor 10 can drive the main shaft 4 to rotate forward and reversely, the outer surface of the main shaft 4 is rotatably sleeved with a control board 2, the control board 2 is provided with a plurality of control boards, and the plurality of control boards 2 are equidistantly distributed on the outer surface of the main shaft 4, the other end of the control board 2 is rotatably connected with a crushing cutter wheel 6, a power box 3 is installed on the side of the control board 2, the output end of the power box 3 is fixedly connected with the crushing cutter wheel 6, the power box 3 provides power for the rotation of the crushing cutter wheel 6, a mud guard 11 is arranged above the main shaft 4, the control board 2 and the crushing cutter wheel 6 are located below the mud guard 11, and the mud guard 11 is connected to the installation mainboard 2. The main board 1 is elastically rotatably connected, and the elastically connected mudguard 11 has a tendency to rotate downward. A contact rod 12 is installed on the side of the control board 2 close to the mudguard 11. The thickness of the contact rod 12 is less than the thickness of the control board 2. One end of the contact rod 12 close to the mudguard 11 is rotatably connected with a roller 13, and the roller 13 is in rolling contact with the mudguard 11. The control board 2 supports the mudguard 11 through the roller 13. The roller 13 reduces the wear caused by the relative movement of the contact rod 12 and the mudguard 11. The connection between the control board 2 and the main shaft 4 is rotatably inserted with an interaxial sleeve 5, and the interaxial sleeve 5 is rotatably sleeved on the outer surface of the main shaft 4. One end of the interaxial sleeve 5 is fixedly connected with a torsion spring 14, and the other end of the torsion spring 14 is fixedly connected to the control board 2. The interaxial sleeve 5 drives the control board 2 to rotate through the torsion spring 14, so that when the crushing cutter wheel 6 is impacted by a hard object, the torsion spring 14 buffers the impact through elastic torsion, thereby reducing the damage to the crushing cutter wheel 6.

The elastic plates 9 apply thrust to the stops 7 to drive the inter-axial sleeve 5 to rotate, and the resistance encountered after the crushing cutter wheel 6 cuts into the soil to a certain depth causes the elastic plates 9 to elastically deform due to the resistance encountered in contact with the stops 7, so that the elastic plates 9 and the stops 7 are misaligned.
[0027] During use, when the motor 10 drives the main shaft 4 to rotate clockwise, the elastic plate 9 contacts the block 7, pushing the shaft sleeve 5 to rotate clockwise, and then the torsion spring 14 has a tendency to drive the control plate 2 and the crushing wheel 6 connected thereto to move downward. After the crushing wheel 6 cuts into the soil to a certain depth, the corresponding elastic plate 9 is dislocated with the block 7 through elastic deformation. According to the different degrees of unevenness of the ground, the control plate 2 rotates to different degrees so that the ground in the depression can be fully crushed by the crushing wheel 6. After the rotary tillage is completed, the motor 10 is started to drive the main shaft 4 to reverse, and the elastic plate 9 applies thrust to the block 7 to push the control plate 2 to rotate upward, driving the crushing wheel 6 to leave the ground.
