DETAILED DESCRIPTION

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] like Figure 1-Figure 2 As shown, an electronically controlled main clutch structure of a silage machine includes a mounting seat 12, a main clutch switch, an electrical control module, and a main clutch motor 11. The top surface of the mounting seat 12 is fixedly connected to a pulley mounting seat 13, and the left side wall of the mounting seat 12 is equipped with a threaded adjustment rod 1. An adjusting connecting rod assembly 9 is equipped on the output shaft of the main clutch motor 11, and a clutch tension spring 6 is equipped on the other end of the adjusting connecting rod assembly 9. The other end of the clutch tension spring 6 is movably connected to a main clutch tensioning wheel mounting seat 3. A return tension spring 2 is equipped on the top of the threaded adjustment rod 1, and the other end of the return tension spring 2 is movably connected to the main clutch tensioning wheel mounting seat 3. A control component is also provided on the main clutch tensioning wheel mounting seat 3.

[0021] like Figure 1 As shown, the electronically controlled main clutch also includes a clutch tension spring 6 and a clutch tension wire. One end of the clutch tension wire is connected to the clutch tension spring 6, and the distance between the clutch tension wire and the clutch tension spring 6 is adjustable. The other end of the clutch tension wire is wound on a winding wheel. The axis of the winding wheel is connected to the clutch brushless motor. The clutch motor is connected to the electrical control module and the clutch switch based on the CAN bus.

[0022] Among them, in order to better realize the main clutch engagement operation, when the driver turns on the main clutch control switch, the main clutch switch module sends an engagement signal to the electrical control module through the CAN bus, and the electrical control module determines whether the current conditions meet the main clutch engagement requirements. If they meet the requirements, the electrical control module sends an engagement command to the main clutch motor 11 through the CAN line. After receiving the engagement command, the main clutch motor 11 drives the motor to rotate forward and tightens the main clutch cable.

[0023] Accordingly, when the driver turns off the main clutch control switch, the main clutch switch module sends a separation signal to the electrical control module through the CAN bus, and the electrical control module determines whether the current conditions meet the main clutch separation requirements. If they meet the requirements, the electrical control module sends a separation command to the main clutch motor 11 through the CAN bus. After receiving the separation command, the main clutch motor 11 drives the motor to reverse and releases the main clutch cable.

[0024] In order to avoid the main clutch mechanism being in the engaged state when the engine is ignited;

[0025] Furthermore, after the electrical control module is powered on, the state of the main clutch motor 11 is first determined. If the main clutch motor 11 is in the engaged state, the electrical control module sends a separation signal to the main clutch motor 11 to drive the main clutch motor 11 to reverse and separate the silage machine working state mechanism.

[0026] like Figure 2As shown, the control assembly includes a main clutch pulley 4 and an engine power output pulley 8, a main clutch belt 7 is drivingly connected between the main clutch pulley 4 and the engine power output pulley 8, and a tensioning pulley 5 is movably connected to the side wall of the main clutch tensioning pulley mounting seat 3 near the right side. The main clutch belt 7 is located at the lower side of the tensioning pulley 5, and the main clutch belt 7 corresponds to the tensioning pulley 5. The main clutch pulley 4 is also drivingly connected to a transmission belt 14.

[0027] A return spring 2 is rotatably connected to the side wall of the main clutch tensioning wheel mounting seat 3 near the left side. The return spring 2 is movably connected to the threaded adjustment rod 1, and the threaded adjustment rod 1 is fixedly connected to the pulley mounting seat 13.

[0028] A motor rotating pull ear 10 is mounted on the output shaft of the main clutch motor 11 , and the bottom end of the adjusting connecting rod assembly 9 is movably connected to the motor rotating pull ear 10 .

[0029] The working principle of the utility model is as follows: when the main clutch motor 11 receives the main clutch engagement command, the output shaft of the main clutch motor 11 rotates clockwise, driving the motor rotating pull ear 10 to rotate clockwise, the motor rotating pull ear 10 drives the adjusting connecting rod assembly 9 to pull downward, the adjusting connecting rod assembly 9 drives the main clutch tensioning wheel mounting seat 3 to rotate clockwise, the left end of the main clutch tensioning wheel mounting seat 3 is pulled upward, so that the return tension spring 2 is in a stretched state; the main clutch tensioning wheel mounting seat 3 is pressed downward at the right end position, so that the tensioning wheel 5 and the main clutch belt 7 are tensioned, at this time the main clutch belt 7 is in a tensioned state, the engine power output belt pulley 8 can drive the main clutch pulley 4 to rotate, and the main clutch engagement is completed;

[0030] When the main clutch motor 11 receives the main clutch separation command, the output shaft of the main clutch motor 11 rotates counterclockwise, driving the motor rotating ear 10 to rotate counterclockwise, and the motor rotating ear 10 drives the adjusting connecting rod assembly 9 to return upward, and the adjusting connecting rod assembly 9 drives the main clutch tensioning wheel mounting seat 3 to rotate counterclockwise, and the left end of the main clutch tensioning wheel mounting seat 3 returns downward, so that the return spring 2 is in a returned state; the right end position of the main clutch tensioning wheel mounting seat 3 is lifted upward, so that the tensioning wheel 5 and the main clutch belt 7 are separated. At this time, the belt 7 is in a relaxed state, and the engine power output pulley 8 cannot drive the main clutch pulley 4 to rotate, and the main clutch separation is completed.

[0031] The working method of the utility model comprises the following steps:

[0032] S1. The main clutch motor 11 receives the main clutch engagement command, and the output shaft of the main clutch motor 11 rotates clockwise, driving the motor rotating pull ear 10 to rotate clockwise. The motor rotating pull ear 10 drives the adjusting connecting rod assembly 9 to pull downward, and the adjusting connecting rod assembly 9 drives the main clutch tensioning wheel mounting seat 3 to rotate clockwise. The left end of the main clutch tensioning wheel mounting seat 3 is pulled upward, so that the return tension spring 2 is in a stretched state; the main clutch tensioning wheel mounting seat 3 is pressed downward at the right end position, so that the tensioning wheel 5 and the main clutch belt 7 are tensioned. At this time, the main clutch belt 7 is in a tensioned state, and the engine power output belt pulley 8 can drive the main clutch pulley 4 to rotate, and the main clutch engagement is completed;

[0033] S2. The main clutch motor 11 receives the main clutch separation command, and the output shaft of the main clutch motor 11 rotates counterclockwise, driving the motor rotating pull ear 10 to rotate counterclockwise. The motor rotating pull ear 10 drives the adjusting connecting rod assembly 9 to return upward, and the adjusting connecting rod assembly 9 drives the main clutch tensioning wheel mounting seat 3 to rotate counterclockwise. The left end of the main clutch tensioning wheel mounting seat 3 returns downward, so that the return spring 2 is in a returned state; the right end position of the main clutch tensioning wheel mounting seat 3 is lifted upward, so that the tensioning wheel 5 and the main clutch belt 7 are separated. At this time, the belt 7 is in a relaxed state, and the engine power output pulley 8 cannot drive the main clutch pulley 4 to rotate, and the main clutch separation is completed.
