Based on the embodiment in the utility model, all other embodiments obtained by those of ordinary skill in the art without paying creative labor are within the scope of the utility model protection.

[0020] Embodiment:

[0021] A kind of ground preparation tool tractor rut elimination mechanism, as shown in Figures 1-4 Including fixed base 1, rut elimination adjustment board 2, rut elimination structure 3 and elimination force elastic adjustment structure 4, rut elimination adjustment board 2 adjustablely installed on fixed base 1.

[0022] The rut elimination adjustment board 2 as claimed in claim 1, Figures 1-3As shown, it includes a vertical adjustment part 21 and a rut removal mounting part 22. The vertical adjustment part 21 is adjustablely mounted on the fixed base 1. Specifically, the vertical adjustment part 21 is provided with a plurality of adjustment positioning holes 211. The vertical adjustment part 21 is provided through the adjustment channel 11 of the fixed base 1, and the adjustment channel 11 of the fixed base 1 is provided with a locking hole 12. The locking hole 12 is perpendicularly connected to the adjustment positioning hole 211. The locking member 6 passes through the locking hole and is inserted into the adjustment positioning hole.

[0023] The rut-removing mounting part 22 is located at the bottom of the vertical adjustment part 21. In this embodiment, the rut-removing mounting part 22 includes a first mounting side plate 221 and a second mounting side plate 222. The channel formed by the opposing arrangement of the first mounting side plate 221 and the second mounting side plate 222 serves as the mounting and folding channel for the rut-removing structure. The tops of the two mounting side plates are fixed to the vertical adjustment part, and the overall height can be adjusted by changing the height of the vertical adjustment part. The rut-removing mounting part 22 is provided with a hinged mounting position, a limiting mounting position, and an elastic mounting position. The elastic mounting position and the limiting mounting position are located on both sides of the hinged mounting position.

[0024] The rut-eliminating structure 3, as described above Figures 1-4 As shown, the device includes a bent plate 31 and a plow tip 32. The upper end of the bent plate 31 extends between two mounting side plates. A rotating pin 8 passes through the bent plate 31 and is positioned between the two mounting side plates, serving as the rotation axis of the bent plate 31. The upper end of the bent plate 31 extends out of the mounting folding channel and is fixedly connected to the end of the force-relieving elastic adjustment structure 4. The plow tip 32 is fixed to the lower end of the bent plate 31, and the plow tip 32 and the lower part of the bent plate 31 serve as the bending and rutting elimination part. Furthermore, the limiting member 5 uses a limiting pin, is installed at the limiting mounting position and is located below the bent plate 31, in order to limit the lower limit position of the bent plate.

[0025] The force-eliminating elastic adjustment structure 4 includes a spring 41, an adjusting shaft 42, an adjusting nut 43, and an adjusting fixing block 44. The adjusting fixing block 44 is fixed to the bent plate 31. The adjusting shaft 42 passes through the adjusting fixing block 44 and protrudes, and is fixed to the upper end of the bent plate 31. Specifically, the part of the adjusting shaft located below the locking block is provided with a U-shaped clip. The upper end of the bent plate 31 extends into the U-shaped clip and is fixed by a fixing pin 7. The fixing pin 7 is installed onto the U-shaped clip by passing a bolt vertically through the hole in the U-shaped clip and the bent plate.

[0026] A spring 41 is fitted onto the portion of the adjusting shaft 42 located above the adjusting fixing block 44, and an adjusting nut 43 is mounted on the adjusting shaft and located above the spring 41. By changing the position of the adjusting nut on the adjusting shaft, the initial elastic force of the spring can be changed, which in turn changes the original force applied by the adjusting shaft to the curved plate, thus setting the plowing depth for the plow tip.

[0027] The position of the rut-elimination adjusting plate 2 can be changed to change the height of the rut-elimination structure 3 and the elastic adjustment structure 4 mounted thereon, so that the rut-elimination structure 3 can eliminate ruts of different depths. The elastic adjustment structure 4 provides an initial elimination force for the rut-elimination structure 3 to eliminate the rut. The bent rut-elimination part extends into the soil around the rut under the initial pressure of the elastic adjustment structure 4, and continuously eliminates the rut during the process of advancing. When the bent rut-elimination part is subjected to the resistance of the soil, the rut-elimination structure rotates around the hinge. When the resistance of the soil is equal to the elastic force of the elastic adjustment structure 4, the bent rut-elimination part no longer extends, that is, the set soil depth is reached. When the rut-elimination process is completed, the resistance suddenly disappears, and the rut-elimination structure 3 rotates reversely around the hinge under the elastic force of the elastic adjustment structure 4 to return to the original position.
