[0030] When it is necessary to replace the wheel on the agricultural machinery, first remove the clamping assembly 6 from the connecting rod 5 so that the clamping assembly 6 no longer clamps and fixes the wheel hub 3, and then the staff pulls the wheel hub 3 to make the spoke 31 away from the mounting plate 2, and at the same time, the limiting rod 7 on the spoke 31 is also disengaged from the limiting hole 21 on the mounting plate 2, until the wheel hub 3 is disengaged from the connecting rod 5, and the wheel is disassembled; when the wheel is installed on the agricultural machinery, the wheel hub 3 is installed on the connecting rod 5 through the connecting hole 32 on the spoke 31, and then the wheel hub 3 is rotated to align the limiting rod 7 on the spoke 31 with the limiting hole 21 on the mounting plate 2, and then the wheel hub 3 is pushed to insert the limiting rod 7 into the limiting hole 21, until the wheel The wheel is fixed by the clamping assembly 6, so when the wheel is replaced, only the clamping assembly 6 needs to be disassembled and assembled, thereby reducing the steps of disassembling and assembling the wheel, thereby improving the replacement speed of the wheel. The coordinated use of the limit rod 7 and the limit hole 21 can avoid the problem of relative rotation between the wheel hub 3 and the mounting disk 2, thereby improving the reliability of the wheel. The provision of multiple limit rods 7 and multiple limit holes 21 improves the reliability of the use of the limit rods 7 and the limit holes 21.

[0031] Furthermore, a support ring 8 is provided in the wheel hub 3, which can improve the supporting effect of the wheel hub 3. The support ring 8 is hollow and a support frame 81 is provided in the support ring 8, which can reduce the weight of the support ring 8 while ensuring the strength of the support ring 8.

[0033] The surface of the connecting rod 5 is provided with an external thread 51, and the connecting rod 5 is engaged with the clamping assembly 6 through a thread. The clamping assembly 6 includes a screw sleeve 62, and a mounting cavity 621 is provided in the screw sleeve 62. A first limiting groove 623 is provided at the top of the mounting cavity 621, and a guide groove 622 is provided on the side wall of the mounting cavity 621; a pressing sleeve 64, the pressing sleeve 64 is installed in the mounting cavity 621, and the inner wall of the pressing sleeve 64 is arranged in a trapezoidal shape. A plurality of positioning blocks 642 are provided on the inner wall of the pressing sleeve 64, and a second limiting groove 643 is provided at the bottom of the pressing sleeve 64. A guide block 641 corresponding to the guide groove 622 is provided on the outer wall of the pressing sleeve 64, and the guide block 641 is slidably connected to the guide groove 622; a connecting block 63, there are multiple connecting blocks 63, all of which are arc-shaped, and all of which are installed in the pressing sleeve 64. An internal thread 631 is provided on the inner wall of the connecting block 63, and the connecting block 63 is threadedly connected to the connecting rod 5. The outer wall of the connecting block 63 is trapezoidally arranged, and the outer wall of the connecting block 63 abuts against the inner wall of the pressing sleeve 64. The top of the connecting block 63 is connected to the first limiting groove 623, and the bottom of the connecting block 63 is connected to the second limiting groove 643. A positioning groove 632 corresponding to the positioning block 642 is provided on the outer wall of the connecting block 63; the nut 61, the nut 61 is screwed on the connecting rod 5, and the nut 61 is located on the connecting rod 5 on the side of the threaded sleeve 62 away from the spoke 31.

[0034] When the clamping assembly 6 is installed on the connecting rod 5, the connecting blocks 63 are vertically installed in the pressing sleeve 64 respectively, and the bottom of the connecting block 63 is inserted into the second limiting groove 643 in the pressing sleeve 64, and then the pressing sleeve 64 and the connecting block 63 are installed in the screw sleeve 62, and the top of the connecting block 63 is connected to the first limiting groove 623 in the screw sleeve 62, so that the setting of the first limiting groove 623 and the second limiting groove 643 can limit the connecting block 63 to maintain a vertical state in the pressing sleeve 64, and then the assembled screw sleeve 62, pressing sleeve 64 and connecting block 63 are installed on the connecting rod 5, wherein the arc-shaped connecting block 63 can better fit with the connecting rod 5, and then the screw sleeve 62 is rotated. Due to the setting of the guide groove 622 and the guide block 641, the pressing sleeve 64 also rotates when the screw sleeve 62 rotates, and due to the setting of the positioning block 642 and the positioning groove 632, the pressing sleeve 64 When rotating, the connecting block 63 can also rotate with it, so that the assembled screw sleeve 62, pressing sleeve 64 and connecting block 63 can rotate on the connecting rod 5 through the internal thread 631 and the external thread 51, until the pressing sleeve 64 abuts against the side wall of the spoke 31 and the pressing sleeve 64 completely enters the installation cavity 621, so that the clamping assembly 6 completes the clamping of the spoke 31, thereby fixing the wheel hub 3, because the inner wall of the pressing sleeve 64 and the outer wall of the connecting block 63 are trapezoidal, and the outer wall of the connecting block 63 abuts against the inner wall of the pressing sleeve 64, so when the pressing sleeve 64 enters the installation cavity 621, it can push the connecting block 63 to squeeze the connecting rod 5, so that the firmness of the connection between the clamping assembly 6 and the connecting rod 5 is improved, and finally the nut 61 is installed on the connecting rod 5 and the nut 61 abuts and presses the screw sleeve 62, so that the screw sleeve 62 can be prevented from loosening.
