[0034] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0035] Example: Figure 1-5 As shown, this utility model provides a technical solution, a traction mechanism, including a central mounting shaft 1, and a bidirectional horizontal and vertical moving mechanism 2 is provided on the outside of the central mounting shaft 1.

[0036] The transposition bidirectional moving mechanism 2 includes a fixed frame 201, a lifting swing rod 202, a lifting telescopic rod 203, a transverse rotating wheel 204, an adjusting frame 205, a transposition telescopic rod 206, a transposition swing rod 207, a swing end block 208, a transposition guide wheel 209, a limit bolt 210, a support telescopic rod 211, a support swing rod 212, and a longitudinal guide wheel 213;

[0037] A fixed frame 201 is fixedly sleeved on one side of the center mounting shaft 1. A lifting swing rod 202 is movably installed on the bottom side of one side of the fixed frame 201. A lifting and retracting rod 203 is movably connected between one end of the fixed frame 201 and the top side of the lifting swing rod 202. A transverse rotating wheel 204 is rotatably installed on one side of the bottom end of the lifting swing rod 202.

[0038] An adjustment frame 205 is fixedly sleeved on the other end of the outer side of the central mounting shaft 1. A displacement telescopic rod 206 is rotatably connected to the top of one side of the adjustment frame 205. A displacement swing rod 207 is rotatably connected between the bottom of one end of the adjustment frame 205 and the end of the displacement telescopic rod 206.

[0039] A limit bolt 210 is movably inserted on one side of the shifting lever 207. A support telescopic rod 211 is movably connected to the top position of the other side of the adjusting frame 205, corresponding to the outer side of the central mounting shaft 1. A support lever 212 is oscillatingly connected to the end of the support telescopic rod 211 and the bottom position of the other side of the adjusting frame 205. A longitudinal guide wheel 213 is rotatably connected to the end of the support lever 212 via a rotating shaft. The transverse rotating wheel 204 can only be raised and lowered along the side of the central mounting shaft 1. The shifting guide wheel 209 can be raised and lowered along the side of the central mounting shaft 1. The swing end block 208 can swing laterally along the end of the lifting lever 202. The outer diameter of the longitudinal guide wheel 213 is larger than the outer diameter of the shifting guide wheel 209. The height of the transverse rotating wheel 204 can be adjusted by extending the lifting lever 202 in conjunction with the fixed frame 201. The extension of the telescopic rod 206, in conjunction with the telescopic rod 207, drives the swing end block 208 and the telescopic guide wheel 209 to deflect. The limit bolt 210 limits the range of motion of the swing end block 208. The transverse wheel 204 and the telescopic guide wheel 209 drive the central mounting shaft 1 to move laterally. The lifting rod 203 drives the transverse wheel 204 to rise. The extension of the support telescopic rod 211, in conjunction with the support rod 212, drives the longitudinal guide wheel 213 to contact the ground. The limit bolt 210 is pulled out so that the telescopic guide wheel 209 deflects to a position coaxial with the longitudinal guide wheel 213. This effectively reduces the lateral footprint of the traction mechanism during the traction process, makes the steering of the traction mechanism more convenient, and effectively improves the traction convenience of the traction mechanism.

[0040] One end of the central mounting shaft 1 is provided with an end traction connection mechanism 3;

[0041] The end traction connection mechanism 3 includes a connecting end plate 301, a connecting movable rod 302, a connecting end frame 303, a connecting end rod 304, a displacement fixing bolt 305, and a connecting top frame 306;

[0042] A connecting end plate 301 is fixedly installed at one end of the central mounting shaft 1. A connecting movable rod 302 is rotatably connected to the end of the connecting end plate 301. A connecting end frame 303 is fixedly installed on one side of the end of the connecting movable rod 302. A connecting end rod 304 is movably connected inside the connecting end frame 303 at a position corresponding to one side of the connecting movable rod 302. A displacement fixing bolt 305 is movably inserted on both sides of the end of the connecting end plate 301. A connecting top frame 306 is fixedly connected to one end of the top surface of the connecting movable rod 302. The connecting movable rod 302 can swing 90 degrees along the end of the connecting end plate 301. The displacement fixing bolt 305 passes through the connecting end plate. The connecting rod 301 and the connecting end plate 301 can connect the connecting rod 302 and its components to the end of the central mounting shaft 1. The connecting end rod 304 and the connecting end frame 303 can connect the connecting rod 302 to the tail of the agricultural machinery. The deflection range of the connecting rod 302 is limited by the displacement fixing bolt 305. The connecting top frame 306 provides auxiliary positioning for the connecting rod 302, ensuring a more stable connection between the central mounting shaft 1 and the tail of the agricultural machinery. This makes the connection of the traction mechanism tighter and more secure during traction, further improving the ease of use of the traction mechanism.

[0043] The top surface of the central mounting shaft 1 is provided with a top splicing connection mechanism 4;

[0044] The top splicing connection mechanism 4 includes a mounting top plate 401, a connecting vertical plate 402, a splicing crossbeam 403, a central connecting frame 404, and an isolation vertical plate 405;

[0045] A mounting plate 401 is fixedly connected to the center of the top surface of the central mounting shaft 1. Connecting vertical plates 402 are fixedly connected to both ends of one side of the mounting plate 401 at positions corresponding to the front of the central mounting shaft 1. A splicing crossbeam 403 is fixedly connected between the two connecting vertical plates 402. A central connecting frame 404 is fixedly connected to the top center of the splicing crossbeam 403. An isolation vertical plate 405 is fixedly connected to one side of the bottom of the splicing crossbeam 403. Connecting holes are provided at the bottom of the connecting vertical plates 402 and the top of the central connecting frame 404. The side edge of the isolation vertical plate 405 extends through... With mounting holes provided, the connecting vertical plate 402 and its components are installed on the top of the central mounting shaft 1 via the mounting top plate 401. The connecting vertical plate 402, together with the connecting bolts, connects the central mounting shaft 1 to the tail of the agricultural machinery. The splicing crossbeam 403 and the central connecting frame 404 limit the connection at the top of the central mounting shaft 1. The isolation vertical plate 405 limits the cable connecting the agricultural machinery and the central mounting shaft 1, thus completing the quick connection between the traction mechanism and the agricultural machinery, and effectively improving the stability and convenience of the traction mechanism connection.

[0046] The working principle and usage process of this utility model are as follows: In practical application, when using the traction mechanism to traction agricultural machinery, the central mounting shaft 1 and its components need to be connected to the appropriate agricultural machinery first. The connecting vertical plate 402 and its components are installed on the top of the central mounting shaft 1 through the mounting top plate 401. The central mounting shaft 1 is connected to the tail of the agricultural machinery through the connecting vertical plate 402 and the connecting bolt. The top of the central mounting shaft 1 is connected and limited by the splicing crossbeam 403 and the central connecting frame 404. Then, the cable connecting the agricultural machinery and the central mounting shaft 1 is limited by the isolation vertical plate 405, thereby completing the quick connection between the traction mechanism and the agricultural machinery, and effectively improving the stability and convenience of the traction mechanism connection.

[0047] When it is necessary to adjust the traction method of the central mounting shaft 1, the height of the transverse rotating wheel 204 is adjusted by extending the lifting swing rod 202 in conjunction with the fixed frame 201. At the same time, the swing end block 208 and the swing guide wheel 209 are deflected by extending the displacement telescopic rod 206 in conjunction with the displacement swing rod 207. When the transverse rotating wheel 204 and the swing guide wheel 209 contact the ground at the same time, the range of motion of the swing end block 208 is limited by the limit bolt 210, so that the axes of the transverse rotating wheel 204 and the swing guide wheel 209 remain parallel. Then, the central mounting shaft 1 is moved laterally by the transverse rotating wheel 204 and the swing guide wheel 209 to complete the tillage work.

[0048] When the traction mechanism needs to be transferred, the lifting and retracting rod 203 drives the transverse rotating wheel 204 to rise, and the support telescopic rod 211 extends to cooperate with the support swing rod 212 to drive the longitudinal guide wheel 213 to contact the ground. The limit bolt 210 is pulled out to make the shifting guide wheel 209 deflect to a position coaxial with the longitudinal guide wheel 213. At this time, the traction mechanism can be longitudinally limited along the central mounting shaft 1, thereby effectively reducing the lateral footprint of the traction mechanism during the traction process, making the turning movement of the traction mechanism more convenient, and effectively improving the traction convenience of the traction mechanism.

[0049] When longitudinal connection is required at the end of the central mounting shaft 1, the connecting movable rod 302 and its components can be connected to the end of the central mounting shaft 1 via the connecting end plate 301. Then, the connecting movable rod 302 is connected to the tail of the agricultural machinery via the connecting end rod 304 in conjunction with the connecting end frame 303. The deflection range of the connecting movable rod 302 is limited by the displacement fixing bolt 305, so that the central mounting shaft 1 can remain stationary during lateral and longitudinal movement. The connecting top frame 306 provides auxiliary positioning for the connecting movable rod 302, ensuring a more stable connection between the central mounting shaft 1 and the tail of the agricultural machinery. This makes the connection during the traction process of the traction mechanism tighter and more secure, further improving the ease of use of the traction mechanism.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
