[0019] Reference Figure 1 The utility model provides an embodiment: a hydraulic motor drives a drum-type grass rake hydraulic device, including a gearbox 1, a gear pump 2, a hydraulic oil tank 3, a control valve group 4, a hydraulic motor 5, a radiator 6, and a tractor power output shaft 7. The gearbox 1 and the gear pump 2 are connected by a spline, and the tractor power output shaft 7 and the gearbox 1 are connected by a spline. The gear pump 2 converts the mechanical energy transmitted from the tractor power output shaft 7 into hydraulic energy through the gear pump 2.

[0020] The hydraulic oil tank 3 is connected to the gear pump 2 through an oil pipe joint, the hydraulic oil tank 3 is connected to the hydraulic motor 5 through an oil pipe joint, the control valve group 4 is arranged between the gear pump 2 and the hydraulic motor 5, the control valve group 4 controls the flow of hydraulic oil to adjust the speed of the hydraulic motor 5, the hydraulic motor 5 is connected to the radiator 6 through an oil pipe joint, the radiator 6 is connected to the hydraulic oil tank 3 through an oil pipe joint, the tractor power output shaft 7 takes power to drive the hydraulic system to achieve a stable supply of power source, the control valve group 4 can accurately control the flow of hydraulic oil, and the hydraulic motor 5 has the characteristics of large torque and smooth operation.

[0021] Working principle: During operation, the tractor's dynamic output shaft transmits power to the gear pump 2 through the gearbox 1, and the gear pump 2 sucks the hydraulic oil out of the hydraulic oil tank 3. The hydraulic oil is controlled by the control valve group 4 to accurately control the flow of the hydraulic oil through the hydraulic motor 5. The hydraulic motor 5 converts hydraulic energy into mechanical energy, and drives the drum mower to rotate through the transmission device to achieve the purpose of mowing. The hydraulic oil from the hydraulic motor 5 is cooled by the radiator 6 and then returns to the oil tank. By adjusting the control of the control valve group 4, the flow of the hydraulic oil can be accurately controlled, so as to adjust the speed of the hydraulic motor 5 to adapt to different operating requirements. At the same time, the mower has its own independent hydraulic system, which also ensures the precise flow required for the hydraulic motor 5 to work, thereby achieving a stable working state of the mower without being affected by the tractor speed and hydraulic flow.
