[0031] Preferably, a rotating shaft 223 is fixedly connected to the lower part of the hinge seat 224, and a support plate 225 is fixedly provided on the rotating shaft 223, so that the support plate 225 rotates synchronously with the rotating shaft 223, and one end of the rotating shaft 223 is arranged through the support plate 225. Specifically, the support plate 225 can be fixedly connected to the rotating shaft 223 by welding, threaded connection, clamping, etc., and is certainly not limited to the above connection methods. For example, the rotating shaft 223 and the support plate 225 are integrally formed.

[0032] As an improvement, Figure 4-Figure 7 As shown, the adjustment component 24 includes: A fixing plate 241, the fixing plate 241 is connected to the bottom of the operating assembly 22, and a first slide groove 2411 is provided at the bottom thereof, and a limiting protrusion 2412 and a guide protrusion 2413 are provided at both ends of the fixing plate 241 respectively; specifically, the fixing plate 241 is mounted on the supporting plate 225 through a fastener, and a second slide groove 2251 adapted to the first slide groove 2411 is provided on the supporting plate 225; An adjusting rod 242, the adjusting rod 242 is slidably disposed on the fixing plate 241 and passes through the limiting protrusion 2412 and the guide protrusion 2413. A handle 243 is disposed at one end of the adjusting rod 242. The handle 243 can be used to pull and rotate the adjusting rod and limit the position of the adjusting rod; The adjusting block 244 is sleeved on the adjusting rod 242 and reciprocates with the adjusting rod 242. The lower end of the adjusting block 244 is slidably arranged in the first sliding groove 2411. Specifically, the adjusting rod 242 is provided with a limiting step 2421. One end of the adjusting block 244 abuts against the limiting step 2421 and reciprocates with the movement of the adjusting rod 242. A stopper 245, the stopper 245 is mounted on one end of the adjusting rod 242, and a notch is provided on the stopper protrusion 2412, the stopper 245 can pass through the notch, and be locked at the edge of the notch after being rotated; The reset member 246 is sleeved on the adjusting rod 242 and is used to reset the adjusting block 244 . Specifically, one end of the reset member 246 abuts against one side of the adjusting block 244 , and the other end abuts against the side of the guide protrusion 2413 .

[0033] It should be noted that if Figure 7 As shown, the adjusting rod 242 is pulled to the right by the handle 243, and the adjusting block 244 is driven to move. At the same time, after the limiting member 245 passes through the limiting protrusion 2412, the adjusting rod 242 is rotated to rotate the limiting member 245 by 90° and clamp it on the right side of the limiting protrusion 2412, so as to fix the position of the adjusting block 244. Under the action of the reset member 246, the limiting member 245 always abuts against the limiting protrusion 2412, so as to achieve stable limiting. At this time, the adjusting block 244 is engaged with the first limiting groove 211, so that the operating assembly 22 and the connecting member 21 are engaged as an integral structure, that is, the operating assembly 22 and the vehicle body 1 are connected as an integral structure, and the vehicle body 1 is controlled to move by the operating assembly 22. When turning, the front wheel 233 at the bottom is a universal wheel structure, and the vehicle body 1 is controlled to swing left and right by the operating assembly 22 to switch the moving direction of the tractor.

[0034] like Figure 6 As shown, when it is necessary to switch the connection state, the limit member 245 is pulled and rotated to align the limit member 245 with the notch. Under the action of the reset member 246, the adjustment block 244 drives the adjustment rod 242 to move leftward, so that the adjustment block 244 is engaged with the second limit slot 2321, so that the operating assembly 22 and the front wheel assembly 23 are connected as an integral structure. The front wheel assembly 23 controls the rotation direction of the front wheel assembly 23 by the swinging of the operating assembly 22, thereby changing the walking direction of the tractor.

[0035] Preferably, Figure 5As shown, a first limiting groove 211 is provided on the connecting member 21, a second limiting groove 2321 is provided on the upper end of the connecting flange 232, and the adjusting block 244 reciprocates between the first limiting groove 211 and the second limiting groove 2321 to switch the connection mode between the operating assembly 22 and the vehicle body 1 or the front wheel assembly 23.

[0036] Specifically, when the adjustment block 244 is engaged with the first limit groove 211, the operating assembly 22 is connected to the vehicle body 1; at this time, by swinging the operating assembly left and right, the rotation angle of the front wheel 233 is changed through the vehicle body 1 to adjust the walking direction of the tractor. The tractor has a large turning radius and runs smoothly, which is particularly suitable for working conditions with heavy loads, low speeds, and large walking space. In addition, when the adjustment block 244 is engaged with the second limit groove 2321, the operating assembly 22 is connected to the front wheel assembly 23. At this time, the swing direction of the front wheel 233 is controlled by the left and right swing of the operating assembly 22, thereby controlling the walking direction of the tractor. The turning radius of the tractor is small, which is more suitable for working conditions with light load, small walking space and fast driving speed.

[0037] Embodiment 2 like Figure 2 , Figure 5 , Fig. 9 , Fig.10 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: In this embodiment, Figure 5 , Fig. 9 As shown, the front wheel assembly 23 includes: A connecting flange 232, the connecting flange 232 is rotatably arranged in the connecting member 21 through a bearing; the operating assembly 22 is rotatably connected in the connecting flange 232 through a rotating shaft 223; specifically, a bearing is arranged between the rotating shaft 223 and the inner wall of the connecting flange 232, so that the rotating shaft 223 is rotatably installed in the connecting flange 232, and the connecting flange 232 can realize self-rotation, thereby driving the front wheel 233 to rotate; A wheel frame 231, wherein the wheel frame 231 is disposed at the bottom of the connecting flange 232; The front wheel 233 is rotatably mounted on the wheel frame 231 via a rotating shaft.

[0038] Further, such as Fig.10As shown, a first rotating position 2311 and a second rotating position 2312 are provided on the side of the wheel frame 231, and the axis of the first rotating position 2311 and the rotating shaft 223 of the operating assembly 22 are located in the same plane; the axis of the second rotating position 2312 and the rotating shaft 223 of the operating assembly 22 are staggered, and the front wheel 233 is rotatably installed in the first rotating position 2311 or the second rotating position 2312.

[0039] It should be noted that the first rotation position 2311 and the second rotation position 2312 can be two through holes set independently of each other, which are used to fix the rotation axis of the front wheel 233. When it is necessary to switch the position of the front wheel 233 between the above two rotation positions, the rotation axis is pulled out and the front wheel 233 is installed in another rotation position to complete the switching of the rotation position of the front wheel 233.

[0040] Furthermore, Fig.10 As shown, the wheel frame 231 is provided with a track 2313 connecting the first rotation position 2311 and the second rotation position 2312, so that the rotation axis of the front wheel 233 can move quickly along the track 2313 between the first rotation position 2311 and the second rotation position 2312, thereby achieving efficient adjustment of the position of the front wheel 233, and cooperating with the locking buckle structure, further achieving efficient and rapid adjustment of the position of the front wheel 233.

[0041] Preferably, the first rotation position 2311 and the second rotation position 2312 are located at the same horizontal height, so that the rotation center of the front wheel remains unchanged after adjustment.

[0042] Preferably, the front wheel assembly 23 also includes: a locking assembly 234, wherein the locking assembly 234 is installed at both ends of the rotating shaft, and is used to fix the front wheel 233 in the first rotation position 2311 or the second rotation position 2312. The locking assembly 234 can be locked by a bolt structure, or it can be a locking buckle structure. The present embodiment is preferably a locking buckle structure to achieve rapid adjustment of the position of the front wheel 233. At the same time, the locking buckle is a commonly used structure, and the detailed structure is not repeated in this application.

[0043] It should be noted that when the front wheel 233 changes direction actively, that is, the swinging direction of the front wheel 233 is changed by external force to control the traveling direction of the tractor, the front wheel 233 is preferably located in the first rotation position 2311 to improve the smoothness, stability and convenience of the steering process.

[0044] When the front wheel 233 changes direction passively, that is, the front wheel 233 acts as a universal wheel, and there is no external force to directly change the walking direction of the front wheel 233, and the passive direction change is formed by the swing of the tractor body 1 and the friction between the front wheel 233 and the ground.

[0045] It should be noted that when the front wheel 233 is located in the first rotation position 2311, if the operating assembly 22 is connected to the vehicle body 1, it is particularly difficult to control the steering of the front wheel 233 through the vehicle body 1, which affects the smoothness of the operation. If the front wheel 233 is to be adjusted to the second rotation position 2312, a force arm structure is formed between the rotation center of the rotating shaft 223 and the second rotation position 2312 to improve the smoothness of the steering of the front wheel 233, thereby improving the operator's physical perception of the tractor.
