[0034] Rotary shovel 13: Installed on the trailer 5 and used for turning over and breaking up the soil blocks plowed up by the plowing shovel 8. The rotary shovel 13 is connected to the rotary transmission mechanism 11 through a support shaft 12 to ensure that the rotary shovel 13 can work synchronously with the plowing shovel 8.

[0035] A hook frame 3 is provided at the tail of the machine head 1, and the hook frame 3 is hooked on the trailer 5; the machine head 1 and the trailer 5 are connected through the hook frame 3, which is convenient for installation.

[0036] The upper end of the plowing shovel 8 is rotatably connected to a rotating arm 7. One end of the rotating arm 7 is fixedly connected to a main shaft 6, and the main shaft 6 is drivingly connected to the output shaft 2 at the tail of the machine head 1; the middle part of the plowing shovel 8 is rotatably connected to a limiting arm 9. One end of the limiting arm 9 is fixedly connected to a rotating shaft 10, and the rotating shaft 10 is rotatably connected to the trailer 5.

[0037] Through the above structure, the rotating arm 7 can pull the plowing shovel 8 up and down. At the same time, under the limiting action of the limiting arm 9 on the plowing shovel 8, the plowing shovel 8 can perform plowing actions.

[0038] The main shaft 6 and the output shaft 2 are connected through a transmission component 4; the transmission component 4 includes a vertical transmission gearbox 41, a transmission shaft 42, and a belt transmission box 43. The output shaft 2 is connected to the transmission shaft 42 through the vertical transmission gearbox 41, and the transmission shaft 42 is rotatably connected to the main shaft 6 through the belt transmission box 43 to realize the output shaft 2 driving the main shaft 6 to operate.

[0039] The rotary transmission mechanism 11 includes a transmission gear 1105, which is fixedly connected to the rotating shaft 10. The transmission gear 1105 is simultaneously meshed with a first one-way rotating wheel 1106 and a second one-way rotating wheel 1102. The first one-way rotating wheel 1106 and the second one-way rotating wheel 1102 are respectively connected to a fixed shaft 1107 and a transmission shaft wheel 1103 in a one-way rotating manner. The first one-way rotating wheel 1106 is meshed with a driven rotating wheel 1101, and the driven rotating wheel 1101 is fixedly connected to the transmission shaft wheel 1103. The transmission shaft wheel 1103 is drivingly connected to the support shaft 12 through a belt 1104; through the transmission of the first one-way rotating wheel 1106, the second one-way rotating wheel 1102, and the driven rotating wheel 1101, the transmission gear 1105 can drive the transmission shaft wheel 1103 to rotate in one direction when rotating clockwise and counterclockwise.

[0041] Two support wheels 14 are symmetrically arranged at the bottom of the trailer 5. The support wheels 14 are used to lift the trailer 5 to ensure the stability of the tractor during operation and reduce friction.

[0042] Working principle: When the tractor head 1 operates, the output shaft 2 drives the main shaft 6 to rotate through the transmission assembly 4. Then, the plowing shovel 8 moves up and down through the rotating arm 7 for plowing operations. The limiting arm 9 is connected to the middle of the plowing shovel 8 and is connected to the trailer 5 through the rotating shaft 10 to limit the lateral movement of the plowing shovel 8, enabling the plowing shovel 8 to form a soil-shoveling and plowing action. The rotary transmission mechanism 11 is used to link the rotary shovel 13 and the plowing shovel 8. When the plowing shovel 8 moves up and down, the rotary transmission mechanism 11 synchronously drives the rotary shovel 13 to rotate, realizing continuous operation of plowing and tilling. Among them, the rotary transmission mechanism 11 is driven by the rotating shaft 10. The rotating shaft 10 is connected to the limiting arm 9. The other end of the limiting arm 9 away from the rotating shaft 10 is the force application end, which has the function of a labor-saving lever during transmission, making the transmission more labor-saving.
