When the adjusting screw 909 is rotated, the adjusting screw 909 rotates, and the spiral transmission between the adjusting screw 909 and the telescopic frame spiral push block 1004 is used to push the telescopic frame. The spiral push block 1004 of the movable telescopic frame moves left and right, thereby driving the slider connected to the end of the telescopic frame 1003 to move horizontally, so that the angle between the two rods in the telescopic frame 1003 is changed, and then the distance between the telescopic bracket 10 and the auxiliary connecting seat 9 is adjusted, thereby changing the width of the auxiliary supporting structure. When the express delivery increases, the capacity of the transport platform can be increased. When the channel is reduced and the transport platform cannot pass through, the structure of the telescopic bracket 10 can be adjusted appropriately according to the channel width, so that the telescopic bracket 10 is retracted inward, so that the agricultural transport platform can pass through the narrow channel.

[0038] Specific usage and function: In the present invention, firstly, the control center can be remotely controlled by the remote controller, and the steering motor 5 and the motor-integrated wheel hub 8 can be controlled by the control center to start the motor-integrated wheel hub 8, so that the motor-integrated wheel hub 8 rotates, and the friction between the motor-integrated wheel hub 8 and the ground drives the carrier platform to move. When the carrier platform turns, the controller is remotely operated by the remote controller, and the steering motor 5 is controlled by the controller to drive the steering driving gear 501 to rotate, and the torque is transmitted through the gear transmission formed by the steering driving gear 501 and the reversing driven gear 702.

Crops, fertilizers, and agricultural tools can be transported through the transport platform, thereby reducing the workload of agricultural workers and improving agricultural efficiency. When the carrying capacity of the transport platform needs to be adjusted, the auxiliary connecting seat 9 and the telescopic bracket 10 need to be installed on the frame 1. During the process, the connecting seat plug plate 901 is directed toward the opening of the plug rack assembly set 101, and the connecting seat plug plate 901 is inserted into the plug rack assembly set 101 from top to bottom. During the insertion process The wedge surface of the plug wedge head 907 is in contact with the inclined surface of the limiting wedge block 103. As the auxiliary connecting seat 9 moves downward, an extrusion force is generated, which pushes the locking plug block 905 toward the middle and compresses the plug block push spring 906 again. When the locking plug block 905 is completely moved below the limiting wedge block 103, the locking plug block 905 moves outward under the thrust of the plug block push spring 906 and is inserted under the limiting wedge block 103, thereby realizing the quick assembly of the auxiliary bracket composed of the auxiliary connecting seat 9 and the telescopic bracket 10. When it is necessary to adjust the distance between the auxiliary connecting seat 9 and the telescopic bracket 10, the adjusting screw 909 is rotated to adjust the distance. The lead screw 909 rotates, and by adjusting the spiral transmission of the lead screw 909 and the telescopic frame spiral push block 1004, the telescopic frame spiral push block 1004 is pushed to move left and right, thereby driving the slider connected to the end of the telescopic frame 1003 to translate, so that the angle between the two rods in the telescopic frame 1003 is changed, and then the distance between the telescopic bracket 10 and the auxiliary connecting seat 9 is adjusted, thereby changing the width of the auxiliary supporting structure, and flexibly adjusting the carrying capacity of the carrying platform; in the parking state, the four integrated motor hubs 8 are controlled to face the center to form an "X" shape, forming a stable parking state.
