[0031] The present invention discloses a traction mechanism of a hybrid tractor and a method for using the same, which has the following beneficial effects:

[0032] 1. When the traction mechanism of the hybrid tractor is connected with the agricultural implement, the hybrid tractor is first started, the traction equipment is brought close to the agricultural implement to be connected, and then the lifting unit is used to drive the mounting seat and the transmission box to move in an arc, at which time the vertical adjustment effect is achieved, so that the equipment mounting block and the drive mounting block outside the mounting seat are moved toward the connecting part of the agricultural implement, and then connected; if the connection cannot be made accurately, the provided moving unit can be used to drive the connecting plate and the universal transmission shaft to slide outward laterally, so that the equipment mounting block and the drive mounting block can be installed and connected with the connecting part of the agricultural implement.

[0033] 2. The traction mechanism of the hybrid tractor is such that when the first hydraulic cylinder and the second hydraulic cylinder are working, the output shafts of the first hydraulic cylinder and the second hydraulic cylinder are contracted inwardly, which can drive the third fixing frame and the positioning bar to move upward in an arc, thereby driving the mounting seat and the transmission box to move upward accordingly. At the same time, both ends of the mounting seat are rotationally connected with the positioning bar, and the upper part of the transmission box is rotationally connected with the end of the output shaft of the first hydraulic cylinder through the third fixing frame.

7. The traction mechanism of a hybrid tractor according to claim 3, characterized in that: The mobile unit comprises: A movable frame (7), the movable frame (7) is slidably arranged inside the mounting seat (2), a fixing bar (701) is fixedly connected to the top of the movable frame (7), and the top of the positioning block (204) is embedded in the top of the fixing bar (701); A connecting frame (702), the connecting frame (702) is fixedly mounted on the top of the fixing bar (701), a rotating ring (703) is fixedly mounted on the top of the connecting frame (702), a rotating groove is formed on the outer side of the end of the transmission sleeve (606) located outside, and the rotating ring (703) is movably sleeved on the inner wall of the transmission groove; The mounting bar (704) is fixedly mounted on the front side of the mounting seat (2), the cross section of the mounting bar (704) is set to be concave, and the mounting bar (704) is fixedly connected to the moving frame (7) via a pin shaft.

8. A method for using a traction mechanism of a hybrid tractor according to any one of claims 1 to 7, characterized in that: The method of use comprises the following steps: Step 1: firstly, the traction mounting frame (1) is mounted on the back of the rear axle of the hybrid tractor, and the transmission shaft (101) is extended outward through the traction mounting frame (1), and at this time, the transmission unit is connected to the end of the transmission shaft (101); Step 2: When connecting with the agricultural implement, first start the hybrid tractor, move the traction device close to the agricultural implement to be connected, and then use the lifting unit to drive the mounting seat (2) and the transmission box (3) to move in an arc, at this time, the vertical adjustment effect is achieved, so that the equipment mounting block (205) and the drive mounting block (302) outside the mounting seat (2) move toward the connecting part of the agricultural implement, and then connect; Step 3: If the connection cannot be made accurately, the mobile unit is used to drive the connecting plate (201) and the universal transmission shaft (301) to slide outward laterally, so that the equipment mounting block (205) and the drive mounting block (302) can be installed and connected with the connecting part of the agricultural implement; Step 4: After the agricultural implement is connected, when the hybrid tractor is turned on, the spherical seat (202) and the positioning ball sleeve (203) can be used to drive the agricultural implement to move, and the positioning ball sleeve (203) rotates relative to the spherical seat (202). When the hybrid tractor turns, the towed agricultural implement can turn accordingly. At the same time, when the agricultural implement needs to be driven to perform agricultural work, the transmission shaft (101) can drive the power output member connected to the drive mounting block (302) to rotate through the transmission unit and the universal transmission shaft (301), thereby achieving the effect of power output to the agricultural implement.
