It is one of the core transmission components of agricultural machinery. The clutch connects and disconnects the engine and the transmission system (gearbox, walking system) by pressing or disengaging, ensuring smooth power transmission or safe disconnection.

[0003] In existing agricultural machinery, clutches are mostly operated manually by levers to engage and disengage them, which is cumbersome. In addition, existing clutches are operated by manipulating the pressure plate, but during the movement of the pressure plate, the spring connecting the pressure plate and the clutch cavity will be compressed. Over time, this will cause the spring to bend, affecting the service life of the clutch. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, an agricultural machinery clutch with wireless control function includes a flywheel 1. A friction plate 2 is installed inside the flywheel 1. A pressure plate 3 is movably installed on one side of the flywheel 1. A spring 4 is fixedly connected in a ring array between one side of the pressure plate 3 and the inner wall of the flywheel 1, with the central axis of the flywheel 1 as the axis. A positioning rod 5 is fixedly installed in a ring array on one side of the pressure plate 3, with the central axis of the pressure plate 3 as the axis. The positioning rod 5 is located inside the spring 4, and the end of the positioning rod 5 away from the pressure plate 3 passes through the flywheel 1. A movable disc 6 is rotatably and slidably installed on the output shaft in the middle of the flywheel 1. The movable disc 6... One end of the positioning rod 5 is pressed inwards. The movable disc 6 is made of wear-resistant material. A controller 7 is installed on the agricultural machinery. A transmission rod 8 is rotatably mounted on one side of the movable disc 6 via a shaft pin. A fixed seat 9 is fixedly mounted on the agricultural machinery. A sliding groove 10 is opened inside the fixed seat 9. A movable block 11 is slidably mounted inside the sliding groove 10. The top of the movable block 11 is rotatably connected to the end of the transmission rod 8 away from the movable disc 6 via a shaft pin. A hydraulic rod 12 is fixedly mounted inside one end of the fixed seat 9. The moving end of the hydraulic rod 12 is fixedly connected to one side of the movable block 11. A connecting sleeve 13 is fixedly mounted in the middle of one side of the movable disc 6. One end of the connecting sleeve 13 has a first extrusion arc surface 14 arranged in a ring around its central axis. A fixed sleeve 15 is fixedly installed on the agricultural machinery. One end of the fixed sleeve 15 has a second extrusion arc surface 16 arranged in a ring around its central axis. The first extrusion arc surface 14 and the second extrusion arc surface 16 are in extrusion contact. The output shaft of the flywheel 1 passes through the connecting sleeve 13 and the fixed sleeve 15. By pressing the button on the handheld remote control, the controller 7 controls the hydraulic rod 12 to operate. The hydraulic rod 12 will drive the movable block 11 to move, and through the transmission rod 8, it will drive the movable disc 6 to... When the output shaft in the middle of the flywheel 1 rotates, the first extrusion arc surface 14 on the connecting sleeve 13 on one side of the movable disc 6 will extrude the second extrusion arc surface 16 on the fixed sleeve 15 fixedly connected to the agricultural machinery. This will cause the movable disc 6 to slide on the outside of the output shaft in the middle of the flywheel 1. The movable disc 6 will directly and gradually release the extrusion positioning rod 5. Through the pull of the spring 4 on the pressure plate 3, the pressure plate 3 will be moved away from the friction plate 2, allowing for gear shifting without manual shifting. This makes operation convenient. During gear shifting, the positioning rod 5 remains inside the spring 4, limiting the deformation of the spring 4 and preventing the spring 4 from twisting and deforming, thus improving the service life of the clutch.

[0023] like Figures 1 to 4 As shown, the end of the positioning rod 5 away from the pressure plate 3 has a rounded corner 17.

[0024] After the gear shift is completed, the flywheel 1 will rotate, and the positioning rod 5 will rotate with the flywheel 1. The rounded corner 17 at the end of the positioning rod 5 can improve the stability of the contact between the movable plate 6 and the positioning rod 5.

[0025] like Figures 1 to 4 As shown, the controller 7 includes a signal receiving module 18, a signal processing module 19, and a control signal output module 20. The signal receiving module 18 is used to receive wireless signals, the signal processing module 19 is used to process wireless signals, and the control signal output module 20 is used to output control signals issued by the signal processing module 19. The control signal output module 20 is electrically connected to the hydraulic rod 12. The controller 7 also includes a control button 21, which is electrically connected to the signal processing module 19. The device that issues the signal can be a remote control.

[0026] By pressing the button on the handheld remote control, the remote control can emit a wireless signal. The signal receiving module 18 will receive the wireless signal, the signal processing module 19 will process the wireless signal and output a control signal to the control signal output module 20. The control signal output module 20 is used to send a control signal to the signal processing module 19 to control the operation of the hydraulic rod 12. Alternatively, the control button 21 on the controller 7 can be pressed directly to control the signal processing module 19 to send a signal directly, and the hydraulic rod 12 will drive the movable block 11 to move.

[0027] This utility model provides an agricultural machinery clutch with wireless control function, and its specific working principle is as follows:

[0028] When the device is in use, if the operator needs to shift gears or control the clutch while operating agricultural machinery, pressing the button on the handheld remote control will send a wireless signal. The signal receiving module 18 will receive the wireless signal, and the signal processing module 19 will process the wireless signal and output a control signal to the control signal output module 20. The control signal output module 20 will send a control signal to the signal processing module 19 to control the operation of the hydraulic rod 12. Alternatively, pressing the control button 21 on the controller 7 will directly send a signal to the signal processing module 19. The hydraulic rod 12 will drive the movable block 11 to move. Through the connection of the transmission rod 8, it will drive the movable disc 6 to rotate outside the output shaft in the middle of the flywheel 1. The first extrusion arc surface 14 on the connecting sleeve 13 on one side of the movable disc 6 will extrude the second extrusion arc surface 16 on the fixed sleeve 15 fixedly connected to the agricultural machinery. This will cause the movable disc 6 to slide outside the output shaft in the middle of the flywheel 1. The movable disc 6 will gradually release the pressure of the positioning rod 5. Through the pull of the spring 4 on the pressure plate 3, the pressure plate 3 will be moved away from the position. Friction plate 2 can be used for gear shifting. After shifting, pressing the button on the handheld remote control will send a wireless signal. The signal receiving module 18 will receive the wireless signal, and the signal processing module 19 will process the wireless signal and output a control signal to the control signal output module 20. The control signal output module 20 is used to send a control signal to the signal processing module 19 to control the operation of the hydraulic rod 12, or the control button 21 on the controller 7 can be pressed directly to control the signal processing module 19 to send a signal. The hydraulic rod 12 will drive the movable block 11 to move in the opposite direction. Through the connection of the transmission rod 8, it will drive the movable disc 6 to rotate in the opposite direction outside the output shaft in the middle of the flywheel 1. The first extrusion arc surface 14 on the connecting sleeve 13 on one side of the movable disc 6 will extrude in the opposite direction to the second extrusion arc surface 16 on the fixed sleeve 15 fixedly connected to the agricultural machinery. This will drive the movable disc 6 to slide in the opposite direction outside the output shaft in the middle of the flywheel 1. The movable disc 6 will directly and gradually extrude the positioning rod 5, which will drive the pressure plate 3 to extrude the friction plate 2, thus realizing the transmission of power.
