A flushing oil tank 8, a gear pump 9 and an oil pump motor 10 are arranged inside the operating frame 1; a control box 2 is arranged on one side of the cycloidal pinwheel reducer 3, and is connected to the circuit of the cycloidal pinwheel reducer 3 to control the working state of the cycloidal pinwheel reducer 3; a flushing oil pipe 7 is arranged on the box body on one side of the test box 51, and the oil outlet faces the clutch to be tested. The flushing oil pipe 7 can rotate on one side of the test box 51 through a fixed shaft seat; the output shaft of the cycloidal pinwheel reducer 3 penetrates into the reduction box body 41 and meshes with the central spline of the reduction driving gear 42; the two ends of the shaft body of the passive double gear 43 are respectively connected to the reduction box body 41; The driving gear 42 is meshed with the large gear in the passive duplex gear 43; the small gear of the passive duplex gear 43 is meshed with the reduction output gear 44; one side of the reduction box output shaft 45 is meshed with the central spline of the reduction output gear 44, and the other side penetrates into the test box 51, and is detachably connected to the test box 51 through the positioning seat 59, and the reduction box output shaft 45 is sleeved with the clutch 52 to be tested in the test box 51 and the spline sleeve 54 in the test box 51 from right to left in sequence; the central spline sleeve of the clutch 52 to be tested is spline-connected with the reduction box output shaft 45; the spline sleeve 54 is transitionally matched with the reduction box output shaft 45, and the outer splines of the spline sleeve 54 are respectively connected with the spline shaft head on the outer shell of the clutch 52 to be tested and the central spline sleeve 54 of the test driving gear 53 The spline is meshed. Considering the service life of the spline shaft head on the outer shell of the clutch 52 to be tested, the spline shaft head is designed as an insert structure, and the material is 20CrMoTi after carbonitriding heat treatment; the output shaft of the clutch test box 5 is sleeved with the test passive gear fork 57, the test passive gear 55 and the inner gear ring 56 from right to left in sequence; the test passive gear fork 57 is connected to the fork driving cylinder 58, the test passive gear fork 57 and the output shaft of the clutch test box 5 are transitionally matched, the test passive gear fork 57 is fixedly connected to the wheel disc of the test passive gear 55, and the test passive gear fork 57 drives the test passive gear 55 to move axially on the output shaft of the clutch test box 5 under the drive of the fork driving cylinder 58;The test passive gear 55 is spline-connected with the output shaft of the clutch test box 5, and the gear teeth of the test passive gear 55 and the test active gear 53 match each other; the inner ring gear 56 is fixedly connected with the test box 51, and the inner ring diameter of the inner ring gear 56 is the same as the diameter of the test passive gear 55 and is provided with gear teeth matching the gear teeth of the test passive gear 55; the output shaft of the clutch test box 5 passes through the test box 51 and is transmission-connected with the input end of the magnetic powder brake assembly 6; the oil pump motor 10 is connected with the gear pump 9; the oil inlet of the gear pump 9 is connected with the oil outlet oil circuit of the flushing oil tank 8, and the oil outlet of the gear pump 9 is connected with the oil inlet oil circuit of the flushing oil pipe 7; an oil outlet is provided at the bottom of the test box 51, and the oil outlet at the bottom of the test box 51 is connected with the oil inlet oil circuit of the flushing oil tank 8. ;

[0023] When in use, the cycloid pinwheel reducer 3 uses the XWD2.2-5-1 / 59-B3 model, with an output torque of 1000N.m and an output speed of about 23.7r / min. The reduction driving gear 42 in the two-section reduction box 4 is a gear with a module of 4 and a number of teeth of 23; the large gear of the passive double gear 43 is a gear with a module of 4 and a number of teeth of 68, and the small gear of the passive double gear 43 is a gear with a module of 4 and a number of teeth of 23; the reduction output gear 44 is a gear with a module of 4 and a number of teeth of 68. After the module and tooth number ratio of the above gears, the torque and speed output by the cycloid pinwheel reducer 3 can be controlled at about 7000N.m and 2.76r / min. Since the load used is the magnetic powder brake assembly 6 with a torque of 400N.m, the magnetic powder brake assembly 6 has limitations in torque, so the power transmission needs to adopt speed increase loading, and the test active gear 53 uses a gear with a module 4 and a number of teeth 48; the test passive gear 55 uses a gear with a module 4 and a number of teeth 32. The test passive gear 55 with a module 4 and a number of teeth 32 can control the speed ratio at 1:1.5, and finally increase the torque of the magnetic powder brake assembly 6 to the standard minimum torque value of 500N.m of the high-speed rice transplanter clutch, and finally adjust the torque to determine the actual minimum torque value of the slippage of the clutch 52 to be tested. When the clutch 52 to be tested needs to be slipped and run-in, it is only necessary to control the fork drive cylinder 58 to shift the test passive gear fork 57, thereby driving the test passive gear 55 to move toward the inner gear ring 56 on the output shaft of the clutch test box 5, until the test passive gear 55 is meshed with the inner gear ring 56. Since the inner gear ring 56 is fixed on the test box 51, the test passive gear 55 cannot drive the output shaft of the clutch test box 5 to rotate after being meshed with the inner gear ring 56. At this time, the load end simulates a locked stop state, thereby achieving the slippage and running-in of the clutch 52 to be tested. By adjusting the passive gear fork 57, the clutch can be switched between the slippage and running-in state and the loaded state simply and quickly. When replacing the clutch 52 to be tested, it is only necessary to remove the positioning seat 59 and rotate the flushing oil pipe 7 to remove and replace the clutch 52 to be tested.

[0024] The above-mentioned usage method can also be realized through other types of cycloid pinwheel reducers and magnetic powder brake components. It is only necessary to adjust the gear ratios and adjust the output torque and load torque to meet the operation requirements of the high-speed transplanter clutch.

[0025] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
