[0010] Figure 2 is a schematic diagram of the present utility model installed at the bottom of the wheeled tractor;

[0011] The present utility model will be further described below with reference to the drawings and embodiments. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] A wheeled tractor rotary mechanism system, referring to Figure 1 , includes a rotary gear disc assembly 8 and a support assembly 13. Among them, a support assembly 13 is provided at the bottom of the rotary gear disc assembly 8. The rotary gear disc assembly 8 includes an upper end fixing seat 5, an upper end fixing bolt 4, a lower end fixing seat 9, a hydraulic drive pump 3, a rotary gear disc 7 and a core shaft 6. The support assembly 13 includes a leg seat 10, an oil cylinder hinge seat 11, a connecting pin 12, legs 16, a leg hinge seat 17, an oil cylinder 14, an oil cylinder connecting pin 18 and a leg connecting pin 1. The upper end fixing seat 5 is installed on the wheeled tractor bottom plate 2 through the upper end fixing bolt 4. There is a core shaft 6 at the center of the rotary gear disc 7. One end of the core shaft 6 is fixedly connected to the upper end fixing seat 5, and the other end of the core shaft 6 is rotatably connected to the lower end fixing seat 9. There is a hydraulic drive pump 3 on the lower end fixing seat 9. The hydraulic drive pump 3 has teeth, and the teeth are meshed with the rotary gear disc 7. The hydraulic drive pump 3 drives the rotary gear disc to rotate; the bottom of the lower end fixing seat 9 is connected to the leg hinge seat 17. The legs 16 are hinged to the leg hinge seat 17 through the leg connecting pin 1. The legs 16 are connected to the leg seat 10. There is an oil cylinder hinge seat 11 on the leg 10. The oil cylinder 14 is hinged to the oil cylinder hinge seat 11 through the connecting pin 12. There is an oil cylinder rod 15 in the oil cylinder 14. The oil cylinder rod 15 is hinged to the lower end fixing seat 9 through the oil cylinder connecting pin 18;

[0013] Further, referring to Figure 1 , the upper end fixing seat 5 and the lower end fixing seat 9 are circular;

[0014] Further, referring to Figure 1, there are four outriggers 16, which are evenly distributed at the bottom of the lower fixed seat 9;

[0015] Further, referring to Figure 1 , there are four hydraulic cylinders 14, which are arranged in parallel with the outriggers 16.

[0016] Referring to Figure 1 , Figure 2 , when the wheeled tractor needs to turn or reverse during field operation, operate the hydraulic cylinder 14. The cylinder rod 15 extends out of the hydraulic cylinder 14 under the action of hydraulic oil. The hydraulic cylinder 14 pushes the outrigger 16 to slide inward through the cylinder hinge seat 11 until the wheeled tractor is lifted and the wheels leave the ground. Then operate the hydraulic drive pump 3. The teeth of the hydraulic drive pump 3 drive the rotating gear disk 7 to rotate around the core shaft 6 until the body of the wheeled tractor rotates to the appropriate direction. Stop the hydraulic drive pump 3 and operate the hydraulic cylinder 14. The cylinder rod 15 retracts into the hydraulic cylinder 14 under the action of hydraulic oil. The hydraulic cylinder 14 pulls the outrigger 16 to slide outward through the cylinder hinge seat 11 until the wheeled tractor falls back and the wheels are in contact with the ground. Then the wheeled tractor can continue to operate;

[0017] The rotating mechanism of this wheeled tractor can also not use the four-foot support method. Just install the rotating gear disk assembly between the engine assembly base frame and the running gear frame. When the tractor reaches the end of the field, raise the farm implement and operate the handle to rotate the rotating gear disk assembly to rotate the upper part of the body, and the running gear does not rotate to achieve a turn-around.
