Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] Example:

[0031] See also Figure 1-Figure 3The present embodiment provides a leveling mechanism of a rotary tiller, including a frame body 1, a leveling unit and a compacting unit. The leveling unit and the compacting unit are installed on the frame body 1. The frame body 1 includes a support frame 101 and side support frames 102 fixedly connected to both sides of the support frame 101. The leveling unit includes two augers 2 rotatably connected to the front end of the bottom of the support frame 101. The two augers 2 are coaxially arranged, and the rotation directions of the two augers 2 are opposite. The augers 2 are used to transport soil from the middle position of the support frame 101 to both sides thereof. The leveling unit also includes a device for driving the augers 2 to rotate. The driving component 3 drives the two augers 2 to rotate and work, thereby spreading the uneven soil in the ground to both sides of the soil groove, so that the soil can be leveled. The compaction unit includes a compaction roller bracket 7 fixedly connected to both sides of the rear end of the bottom of the support frame 101, and a compaction roller 8 is installed between the two compaction roller brackets 7. The compaction roller 8 is provided with a counterweight adjustment structure, and the counterweight adjustment structure is used to adjust the weight of the compaction roller 8. When the rotary tiller moves, the compaction roller 8 rotates accordingly to compact the soil. The weight of the compaction roller 8 can be adjusted by the counterweight adjustment structure to adjust the compaction degree of the soil.

[0032] As an implementation method of this embodiment, Figure 1 As shown, the driving assembly 3 includes a driving motor fixedly installed on both sides of the top of the supporting frame 101, a driving sprocket fixedly connected to the output end of the driving motor, and a driven sprocket fixedly sleeved on the two augers 2. A chain is connected between the driving sprocket and the corresponding driven sprocket. A distribution box 4 and a power supply module 5 are also installed on the top of the supporting frame 101. The power supply module 5 is electrically connected to the distribution box 4, and the distribution box 4 is electrically connected to the driving motor. The power supply module 5 and the distribution box 4 supply power to the driving motor. The driving motor drives the driving sprocket to rotate, and the driving sprocket drives the driven sprocket to rotate through the chain, thereby driving the augers 2 to rotate, and the soil is leveled.

[0033] In this embodiment, the outer sides of the driving sprocket, the driven sprocket and the chain are collectively covered with a protective cover to prevent the driving sprocket, the driven sprocket and the chain from being exposed, thereby improving the protective effect.

[0034] In this embodiment, if Figure 1 As shown, a protection beam 6 is fixedly connected to the front end of the bottom of the support frame 101 at the auger 2. The protection beam 6 protects the auger 2 to prevent people from accidentally touching the auger 2 and causing injuries, thereby improving safety.

[0035] In this embodiment, if Figure 2As shown, a mounting groove 701 is provided on the compaction roller bracket 7, and the mounting groove 701 is provided longitudinally. An opening is provided between the top of the mounting groove 701 and the side wall of the compaction roller bracket 7. A rotating shaft 801 is fixedly connected at the center of the compaction roller 8. Both ends of the rotating shaft 801 extend to the outside of the compaction roller 8. The end of the rotating shaft 801 passes through the opening and is placed in the mounting groove 701, so as to facilitate the installation of the compaction roller 8 and the compaction roller bracket 7.

[0036] As an implementation method of this embodiment, Figure 3 As shown, the counterweight adjustment structure includes a counterweight installation cavity 802 opened in the compaction roller 8, and the counterweight installation cavity 802 is opened along the axial direction of the compaction roller 8. The counterweight installation cavity 802 is used to fill and install a counterweight column. The counterweight column is installed in the counterweight installation cavity 802 to adjust the weight of the compaction roller 8 and adjust the compaction degree of the soil. It should be noted that the weight of the counterweight column can be designed to different weights according to different materials, so that the weight of the compaction roller 8 can be selected according to needs.

[0037] In this embodiment, a plurality of counterweight installation cavities 802 are symmetrically opened along the axial direction of the compacting roller 8. The number of counterweight columns installed in the counterweight installation cavity 802 can be selected according to demand, so that the weight of the compacting roller 8 can be selected according to demand. It should be noted that the counterweight columns need to be installed symmetrically on both sides of the compacting roller 8 to ensure the stability of the rotation of the compacting roller 8.

[0038] In this embodiment, if Figure 3 As shown, one end of the counterweight installation cavity 802 is located at the end of the compacting roller 8 and is provided with a receiving groove 803, and a blocking cover 804 is threadedly connected to the receiving groove 803. The diameter of the receiving groove 803 is larger than the diameter of the counterweight installation cavity 802. After the counterweight column is installed in the counterweight installation cavity 802, the blocking cover 804 can be connected to the receiving groove 803 to fix the position of the counterweight column in the counterweight installation cavity 802, thereby avoiding the problem of the counterweight column shaking or falling out.

[0039] In this embodiment, if Figure 3 As shown, a twist handle is fixedly connected to one side of the blocking cover 804, and the provided twist handle facilitates the twisting installation and removal of the blocking cover 804. The thickness of the blocking cover 804 plus the twist handle is less than the depth of the accommodating groove 803, so that the blocking cover 804 and the blocking cover 804 will not protrude from the end of the compacting roller 8, causing obstacles to the rotation of the compacting roller 8.

[0040] As an implementation method of this embodiment, Figure 1As shown, a plurality of support wheels 103 and guide wheels 104 are installed at the bottom of the side support frame 102. The guide wheel 104 is placed on the side of the support wheel 103 close to the support frame 101. The support wheel 103 is attached to the ground soil, and the guide wheel 104 is attached to the inner side of the groove, so that it can better fit the terrain to prevent deviation during operation. In other embodiments, the side support frame 102 is also provided with an adjustment structure for adjusting the height of the support wheel 103 and the guide wheel 104 to achieve leveling and compacting of soil with different height requirements.

[0041] Working principle: When in use, the driving motor drives the active sprocket to rotate, and the active sprocket drives the driven sprocket to rotate through the chain, thereby driving the auger 2 to rotate. The two augers 2 are coaxially arranged, and the two augers 2 rotate in opposite directions, so that the uneven soil in the ground is spread to both sides of the soil groove to level the soil. At the same time, the compaction roller 8 rotates accordingly to compact the soil. When it is necessary to adjust the compaction degree of the soil, a counterweight column is installed in the counterweight installation cavity 802, and the baffle 804 is connected to the accommodating groove 803, so that the position of the counterweight column in the counterweight installation cavity 802 is fixed. The counterweight columns of different materials and the number of counterweight columns can be selected according to needs, so that the weight of the compaction roller 8 can be selected according to needs, which is used to adjust the weight of the compaction roller 8 and adjust the compaction degree of the soil.

[0042] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
