Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a separation control structure of an agricultural machinery clutch and agricultural machinery equipment. Background Art

[0002] At present, the transmission of the power part and the working part of various agricultural machinery is mainly achieved by the separation and combination of the manual mechanical operation clutch. When the operator controls the clutch lever, the clutch lever drives the clutch separation claw to rotate through the connecting rod system, and the clutch separation claw pushes the clutch release bearing during the rotation, so that the clutch release bearing presses against the spring sheet of the clutch pressure plate, and the release bearing continues to apply pressure, and the spring sheet of the pressure plate is compressed, thereby releasing the pressure of the pressure plate on the driven plate; because the pressure is released, the driven plate is separated from the flywheel. Once the driven plate is separated from the flywheel, the engine power is no longer transmitted to the transmission input shaft, thereby realizing the cutting off of power transmission, which allows the operator to smoothly perform the shifting operation. On the contrary, when the operator releases the clutch lever, the pressure is released from the spring sheet of the pressure plate, the pressure plate presses the driven plate again, the driven plate is combined with the flywheel again, and the engine power is transmitted to the transmission input shaft again.

[0003] During the working process, if the gear position needs to be changed, the steps of acting on the clutch lever, moving the shift lever, and releasing the clutch lever are repeated. In some more complex working environments, the working speed of agricultural machinery needs to be adjusted continuously, which requires frequent gear shifting operations, that is, the driver needs to constantly operate the clutch lever, which will increase the driver's operating intensity and easily cause fatigue. Utility Model Content

[0004] In view of the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: how to provide a clutch separation control structure that can selectively operate the clutch separation and engagement, which can be controlled by electronic control or remote control, or by manual mechanical control, thereby reducing the operating intensity of the driver when the machine is operated for a long time and improving the level of automated operation.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A clutch body includes a clutch body provided with a clutch release claw synchronously rotated and mounted on a clutch release seat, and also includes a hand-pull clutch device and a control clutch device;

[0007] The hand-pull clutch device includes a rotatable rotating member, the rotation plane of the rotating member is parallel to the rotation plane of the clutch separation claw, a pull rod is arranged between the rotating member and the clutch separation claw, a pull rod strip hole extending along the length direction of the pull rod is penetrated on the rod body of the pull rod, a sliding pull block which can slide with it along its extension direction and rotatably cooperate with the pull rod strip hole is penetrated in the pull rod strip hole, one end of the pull rod is rotatably connected to the clutch separation claw, and the sliding pull block is fixedly connected to the rotating member, when the rotating member rotates, the sliding pull block can abut against one end of the pull rod strip hole along the extension direction of the pull rod strip hole, so that the sliding pull block can pull the pull rod to drive the clutch separation claw to rotate, and a hand control device which can act on the rotating member to rotate the rotating member is installed on the rotating member;

[0008] The clutch control device includes a telescopic drive device, a telescopic rod that can be telescoped extends from the front end of the telescopic drive device, a push rod is fixedly connected to the telescopic rod, the push rod is penetrated by a push rod strip hole extending in a direction parallel to the telescopic direction of the telescopic rod, a sliding push block that can slide with the push rod along its extension direction and rotatably cooperate with the push rod strip hole is penetrated in the push rod strip hole, the rear end of the telescopic drive device is rotatably connected to a fixing member for installing the telescopic drive device, the rotation plane of the telescopic drive device is parallel to the rotation plane of the clutch separation claw, the sliding push block is fixedly connected to the clutch separation claw, and when the telescopic rod is extended outward, one end of the push rod strip hole along its extension direction can abut against the sliding push block, so that the push rod can push the sliding push block to drive the clutch separation claw to rotate.

[0009] In the utility model, the hand-pull clutch device and the control clutch device are respectively provided to control the separation of the clutch, and at the same time, they are independent of each other and do not affect each other. In the hand-pull clutch device, after the driver pulls the hand control device, the rotating member is driven to rotate, and at the same time, the sliding block fixed on the rotating member also starts to rotate. Relative to the pull rod, the sliding block rotates in the pull rod bar hole and moves toward one end of the pull rod bar hole. After abutting against one end of the pull rod bar hole, it can drive the pull rod to move, and the crank rocker mechanism formed by the pull rod and the clutch separation claw is combined to synchronously drive the clutch separation claw to rotate, so as to achieve the separation of the moving plate and the flywheel. During the rotation of the clutch separation claw, the sliding push block will also rotate. Since the direction of rotation of the sliding push block is the same as the direction in which the telescopic rod extends to push the sliding push block to rotate, when the telescopic rod is stationary, the sliding push block will move toward the other end of the push rod bar hole, and at this time, the sliding push block will not be affected by the telescopic rod.

[0010] In controlling the clutch device, the driver only needs to control the telescopic drive device, which can be a switch button or other related electronic control device. The telescopic drive device drives the telescopic rod to extend outward, and accordingly makes one end of the push rod strip hole abut against the sliding push block. Combined with the telescopic drive device itself being able to rotate, it can then push the sliding push block to rotate, that is, drive the clutch separation claw to rotate. Combined with the above analysis, when the clutch separation claw rotates, it drives the pull rod to move in the opposite direction, causing the sliding pull block to move in the opposite direction in the pull rod strip hole, and will not affect the rotating parts. In this way, the driver can choose different clutch separation control modes to operate when shifting gears.

[0011] As an optimization, the clutch separation claw includes a claw sleeve and a hand-pull drive arm and a control drive arm which are arranged at intervals around the claw sleeve center line direction, the hand-pull drive arm and the control drive arm extend in the radial direction of the claw sleeve respectively, the pull rod is rotatably connected to the hand-pull drive arm, and the sliding push block is fixedly connected to the control drive arm. The two drive structures are separated from each other to avoid any influence.

[0012] As an optimization, a rotating arm is formed on the rotating member, the sliding block is fixedly connected to the rotating arm, a transmission connection hole is penetrated on the rotating arm along a direction perpendicular to the rotation plane of the rotating member, the distance between the transmission connection hole and the rotation center of the rotating member is greater than the distance between the sliding block and the rotation center of the rotating member, the transmission member includes a transmission rod, one end of the transmission rod connected to the rotating member is bent to form a hook arranged at a right angle to the transmission rod, the hook passes through the transmission connection hole and rotates with the transmission connection hole, and one end of the hook passing through the transmission connection hole is provided with a limit pin for limiting the hook. The farther the distance between the hook and the rotating sleeve is, the larger the force arm formed, and the easier it is to rotate the rotating sleeve.

[0013] As an optimization, a return spring capable of returning the rotating member to an initial rotation position is installed on the rotating member, and a reset spring capable of returning the clutch claw to an initial rotation position is installed on the clutch claw. The return spring and the reset spring are provided to directly control the reset of the rotating member and the clutch claw.

[0014] As an optimization, the pull rod includes a manual adjustment screw and a manual adjustment strip, one end of the manual adjustment strip is threadedly connected to the manual adjustment screw and can be rotated along the length direction of the manual adjustment screw, and the manual adjustment screw is also threadedly matched with a manual adjustment locking nut for locking the manual adjustment strip on the manual adjustment screw, and the pull rod bar hole is located on the manual adjustment strip, and the extension direction of the pull rod bar hole is parallel to the length direction of the manual adjustment screw. The manual adjustment screw and the manual adjustment strip are threadedly matched to achieve different lengths.

[0015] As an optimization, an adjustment thread is provided on the rod body of the telescopic rod along its length direction, one end of the push rod is threadedly connected to the telescopic rod through the adjustment thread, and the telescopic rod is also threadedly equipped with an automatic adjusting locking nut for locking the push rod on the telescopic rod.
