Description

Technical Field

[0001] The present application belongs to the technical field of agricultural machinery, and specifically relates to a lifting-type agricultural machinery shifter and a method of using the same. Background Art

[0002] Agricultural machinery refers to the various types of mechanical equipment used in agricultural production processes, including tillage, sowing, fertilizing, irrigation, harvesting, transportation, and processing. It is a crucial material foundation of modern agriculture, significantly improving agricultural production efficiency, reducing labor intensity, and increasing the yield and quality of agricultural products by replacing human and animal power with mechanized operations.

[0003] At present, agricultural machinery needs to adjust its travel speed according to the working requirements. When adjusting, the hand ball is usually operated to drive the speed change control system through spatial displacement and force transmission, thereby changing the gear of the agricultural machinery gearbox to achieve the purpose of changing the travel speed. The existing control systems on the market usually adopt a combination of left and right or pressing to select left and right gears and shift gears forward and backward to achieve the purpose. The former requires a larger movement space, which brings about adverse factors such as poor mechanical ergonomics and increased costs due to increased cab space. The latter has the disadvantages of requiring body force during operation, changing body coordination, reducing operation safety, and poor user experience. Summary of the Invention

[0004] The purpose of this application is to provide a lifting type agricultural machinery shifter and a method of using the same to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] A lifting type agricultural machinery shifter and a method of using the same, comprising:

[0007] A base and a plurality of mounting holes provided on the base, a mounting seat welded to the top of the base, and a shift assembly provided on the mounting seat;

[0008] The shift assembly includes rocker arm 1, rocker arm 2 and a movable block arranged between the rocker arm 1 and rocker arm 2. A joystick is fixedly connected to the top of the movable block. The rocker arm 1, rocker arm 2 and movable block are all movably mounted on the inner side of the mounting seat through a rotating shaft.

[0009] Preferably, the shift assembly further comprises a slide groove 1, which is provided on a rocker arm 1, a clamping groove 1 is provided at the top of the middle position of the slide groove 1, and a transverse pin 1 is fixedly connected to one side of the movable block.

[0010] Preferably, the shift assembly further comprises a second slide groove, which is provided on the second rocker arm, a second clamping groove is provided at the bottom at the middle position of the second slide groove, and a second transverse pin is fixedly connected to the other side of the movable block.

[0011] Preferably, the shift assembly further includes flexible shafts on both sides, and the flexible shafts on both sides are respectively installed at the bottom of rocker arm 1 and rocker arm 2.

[0012] Preferably, the transverse pin 1 is arranged inside the slide groove 1, and the slot 1 and the transverse pin 1 are arranged to have corresponding sizes.

[0013] Preferably, the second transverse pin is arranged inside the second slide groove, and the second transverse pin is arranged to correspond in size to the second card groove.

[0014] Preferably, S1 pull-up gear selection: according to the power required for the operation of the agricultural machinery, the driver pulls up the joystick with his fingers to drive the movable block to move upward to a first preset height, so that the cross pin 1 and the card slot 1 are axially aligned to form a rigid transmission connection. At this time, the driver maintains the pulling state and pushes the joystick forward or backward to drive the rocker arm 1 to swing back and forth with the rotating shaft as the fulcrum, so that the swing of the rocker arm 1 is transmitted to the flexible shaft, thereby triggering the engagement or disengagement of the corresponding gear of the gearbox;

[0015] S2 reset preparation: The driver presses down the joystick, and the movable block falls back to the initial position, so that the cross pin 1 is out of contact with the slot 1, and the gear is returned to the initial state, preparing for the next gear shift operation;

[0016] S3 Push-to-Select: The driver presses the joystick downward with his finger, driving the movable block to move downward to the second preset height, so that the second cross pin and the second slot are axially aligned, forming a rigid transmission connection. At this time, the driver keeps the joystick pressed and pushes the joystick forward or backward, driving the second rocker arm to swing back and forth with the rotating shaft as the fulcrum. The swing of the second rocker arm is transmitted to the flexible shaft, thereby triggering the engagement or disengagement of the corresponding gear of the transmission;

[0017] S4 gear reset: After the gear shift is completed, the driver pulls the joystick and the movable block falls back to the initial position, causing the second cross pin to disengage from the second slot and returning the gear to its initial state.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) By designing a shift assembly, when shifting gears in agricultural machinery, the user can lift the joystick with their fingers to move the movable block to a preset height, align the cross pin 1 with the card slot 1, and then move the joystick forward or backward. The joystick drives the rocker arm 1 on the corresponding side to swing forward or backward, so that the rocker arm 1 drives the flexible shaft to move axially, thereby realizing the gear shift of the transmission. With the above design, the joystick movement mode can be changed from a combination of forward, backward, left, and right movements or an up, down, front, and back combination to a method of pulling with fingers and swinging forward and backward to shift gears. While reducing the use space of the agricultural machinery cab, it is ensured that the body is not subjected to left and right forces when shifting gears. The shifting can be completed only by the movement of the hands, which does not affect the coordination of the body during driving, greatly improves the operating safety, and truly brings a car-like operating experience.

[0020] (2) By designing a shift assembly, when shifting gears in agricultural machinery, the user can lift the joystick with their fingers to move the movable block to a preset height, align the first cross pin with the first slot, and then move the joystick forward or backward. The joystick drives the first rocker arm on the corresponding side to swing forward or backward, so that the first rocker arm drives the axial movement of the flexible shaft, thereby realizing the gear shift of the transmission; the user can press the joystick with their fingers to move the movable block to a preset height, align the second cross pin with the second slot, and then move the joystick forward or backward. The joystick drives the second rocker arm on the corresponding side to swing forward or backward, so that the second rocker arm drives the axial movement of the flexible shaft, thereby realizing the secondary shift of the transmission gear; this design can avoid the large spatial movement of the traditional left and right gear selection, and reduce the operation time by more than 40%. At the same time, the preset height difference forms a mechanical interlocking mechanism to prevent accidental touch of the lifting and pressing modes, thereby improving the accuracy of gear shifting.
