[0027] The present utility model will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. In the description of the present utility model, it should be understood that unless otherwise specified, the meaning of "a plurality" is two or more.

[0028] Refer to Figure 1 , a drive system architecture of a specific embodiment of the present utility model, includes a frame structure 1, a front-wheel steering structure 2, a rear-wheel steering structure 3, and a driving motor 31. The driving motor 31 is arranged at the rear end of the frame structure 1 and close to the rear-wheel steering structure 3. Both the front-wheel steering structure 2 and the rear-wheel steering structure 3 are connected to the frame structure 1, and the rear-wheel steering structure 3 is adapted to rotate directionally to generate a forward or backward driving force on it via the driving motor 31. The front-wheel steering structure 2 is adapted to rotate circumferentially to guide the feeding vehicle to turn.

[0029] Specifically, the frame structure 1 includes two main frame beams 11 arranged in parallel. There are also multiple secondary frame beams 12 between the two main frame beams 11. Vertical beams 13 are respectively provided at both ends of each main frame beam 11, and the vertical beams 13 are suitable for installing the front protection structure and the rear protection structure of the feeding vehicle. The multiple secondary frame beams 12 can further reinforce the two main frame beams 11 to ensure the stability of the frame structure 1 of the entire drive system architecture. The vertical beams 13 provided at both ends of the main frame beams 11 are used to install and fix the protection structure, and the protection structure can improve the safety of the feeding vehicle during driving.

[0030] See Figure 1 and Figure 2 , the front wheel steering structure 2 is connected to the main frame beam 11 via the mounting seat 14, and the front wheel steering structures 2 installed on the two main frame beams 11 are symmetrically arranged. The front wheel steering structure 2 includes a rotating seat 21, a connecting arm 22, and a roller 23. The rotating seat 21 is arranged on the mounting seat 14. One end of the connecting arm 22 is connected to the rotating seat 21, and the other end of the connecting arm 22 is connected to the roller 23, so as to be able to drive the connecting arm 22 and the roller 23 connected to the connecting arm 22 to rotate along with the rotation of the rotating seat 21. Therefore, the rotation of the rotating seat 21 drives the rotation of the roller 23, and when the roller 23 rotates, the two rollers 23 rotate synchronously to ensure the consistency during the movement.

[0031] Specifically, a mudguard 24 is also provided on the mounting seat 14. The mudguard 24 is fixedly connected to the mounting seat 14, and the extending direction of the mudguard 24 extends in the front and rear moving directions of the feeding vehicle to form an arc-shaped structure. It should be noted that this arc-shaped structure can be a circular arc-shaped structure or other similar shape structures. In this embodiment, the mudguard 24 is composed of three straight plates. Among them, the straight plate arranged in the middle is horizontally arranged, and the two straight plates connected to both ends of the middle straight plate are obliquely arranged towards the ground, and the finally formed structure is also called an arc-shaped structure.

[0032] More specifically, the rotating seat 21 includes a base 211 and a rotating end 212. Multiple fixing holes are provided on the base 211, and fixing members are suitable for being embedded in each fixing hole. The fixing members are suitable for passing through the mudguard 24 and being fixedly connected to the mounting seat 14. The rotating end 212 is fixedly connected to the base 211 to be able to rotate circumferentially on the base 211. The circumferential rotation of the rotating end 212 drives the circumferential rotation of the connecting arm 22, and the connecting arm 22 can drive the roller 23 to perform circumferential rotation, thereby realizing the steering guidance function of the front wheel.

[0033] See Figure 1 and Figure 3, the rear-wheel steering structure 3 includes a drive motor 31, a coupling 32, a wheel 33, and a mounting bracket 34. The mounting bracket 34 is connected to the main frame beam 11. The coupling 32 is coaxially connected to multiple vehicles. The drive motor 31 is drivingly connected to the wheel 33 via the coupling 32 to drive the coaxial rotation of each wheel 33. Here, since the rear-wheel steering structure 3 does not have a rotating structure to drive its rotation, the rear-wheel steering structure 3 can only achieve directional movement, that is, it can only rotate forward or backward to drive the feeding vehicle to move forward or backward.

[0034] Specifically, the mounting bracket 34 laterally extends multiple support rods 35. The multiple support rods 35 are simultaneously connected to a protective plate 36. The protective plate 36 covers the upper part of the wheel 33, and both ends of the protective plate 36 extend downward to the lower part of the wheel 33. The protective plate 36 is arc-shaped. The multiple support rods 35 are respectively fixedly connected to the upper surface of the arc-shaped protective plate 36 to block the mud and water carried by the wheel 33 from adhering to the bottom of the frame structure 1 when the wheel 33 rotates.
