[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 4 , the detachable and maintainable paddy field land preparation machine plow wheel provides two technical solutions:

[0025] The first implementation manner: It includes a mounting shaft 1 and a plow wheel body 2. The end of the mounting shaft 1 is provided as a spline shaft 11. The plow wheel body 2 is sleeved outside the spline shaft 11, and the plow wheel body 2 is fixed on the mounting shaft 1 through a quick installation mechanism. The quick installation mechanism includes:

[0026] A mounting assembly 4. The mounting assembly 4 includes a circular plate 41. The back surface of the circular plate 41 is fixedly connected with a cylinder 42. The end of the mounting shaft 1 is provided with a cylindrical groove 43. Four L-shaped grooves 44 are equidistantly arranged along the circumferential direction on the inner surface of the cylindrical groove 43. Four mounting blocks 45 that are matched with the L-shaped grooves 44 are arranged along the circumferential direction on the surface of the cylinder 42. The back surface of the circular plate 41 is fixedly connected with a limiting spring 46, and the limiting spring 46 is sleeved outside the cylinder 42. The other end of the limiting spring 46 is fixedly connected with a ring 47. Four pressing rods 48 are equidistantly fixedly connected along the circumferential direction on the surface of the ring 47, and the pressing rods 48 are used to press the plow wheel body 2.

[0027] When installing the plow wheel body, operate through the mounting assembly. When installing, only need to rotate the circular plate, and the structure is simple, which improves the convenience of the device during use.

[0028] The second implementation mode, the main difference from the first implementation mode is as follows: The anti-theft component 5 is specifically used to cooperate with the installation component 4 to complete the installation and disassembly operations. The anti-theft component 5 includes a special disassembly tool and a protective sleeve 57. The special disassembly tool includes an L-shaped handle rod 51, and the other end of the L-shaped handle rod 51 is fixedly connected with a mating block 52. The back of the mating block 52 is fixedly connected with two upper and lower fixing plates 53. A plurality of limiting tooth grooves 54 are equidistantly arranged on the opposite sides of the two fixing plates 53. The front of the circular plate 41 is fixedly connected with a fixing block 55. A plurality of limiting teeth 56 that cooperate with the limiting tooth grooves 54 are equidistantly fixedly connected to the top and bottom of the fixing block 55. The protective sleeve 57 is fixedly connected to the front of the plow wheel body 2. A mating slot 58 having the same shape as the mating block 52 is provided on the front of the protective sleeve 57.

[0029] The installation component 4 is operated through the anti-theft component 5, so that the plow wheel body can only be installed and disassembled through a special disassembly tool, avoiding the problem of theft and improving the safety of the device during use.

[0030] When installing the plow wheel body 2, the plow wheel body 2 is sleeved on the spline shaft 11, and the fixing plates 53 on the special disassembly tool are aligned with the fixing block 55, that is, the limiting teeth 56 are aligned with the limiting tooth grooves 54. Then, the whole installation component 4 is placed in the protective sleeve 57, and the installation block 45 is aligned with the L-shaped groove 44, and the cylinder 42 is inserted into the cylinder groove 43. At this time, the limiting spring 46 is compressed. By rotating the mating block 52 through the L-shaped handle rod 51, the circular plate 41 is rotated. The rotation of the circular plate 41 causes the installation block 45 to enter the bent part of the L-shaped groove 44. Furthermore, the pressure rod 48 is pressed against the installation shaft 1 by the reaction force of the limiting spring 46, so that the position of the plow wheel body 2 is fixed. In addition, when disassembling, the mating block 52 is aligned with the mating slot 58, and the mating block 52 is completely inserted into the protective sleeve 57. At this time, the limiting tooth grooves 54 are aligned with the limiting teeth 56. Then, rotating the L-shaped handle rod 51 can release the installation of the plow wheel body 2.
