Description

Technical Field

[0001] This utility model relates to an electric lifting controller for agricultural machinery, belonging to the field of electric lifting control technology for agricultural machinery. Background Technology

[0002] Tractors typically use hydraulic suspension systems to attach implements for field operations. These systems control hydraulic cylinders via hydraulic directional valves to raise or lower the implements, adjusting their working depth. Wheeled tractors generally have rear-mounted implements. Since the lift mechanism is not directly connected to the power output, in normal operation, a hydraulic clutch controls the normal or interrupted power output, and then the lift handle on the lift mechanism is operated to raise or lower the implement.

[0003] Existing agricultural machinery lifting control systems utilize a joystick located in the cab. This joystick has two positions (lifting and lowering), and the lifting and lowering of the implement is controlled by a multi-way hydraulic valve via a mechanical transmission system. This mechanical lifting control method has several drawbacks: firstly, the mechanical transmission system is complex and has frictional resistance, making it difficult and inconvenient to operate; secondly, the joystick only has two positions for on / off digital control, making it impossible to control the lifting and lowering speed of the implement. In practical applications, when the lifting and lowering speed of the implement is too fast, the accuracy of the implement's movements cannot be guaranteed.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing an electronically controlled lifting controller for agricultural machinery. By replacing mechanical transmission with electronic control, the operation method becomes simple and convenient; it can control the lifting or lowering speed of agricultural machinery, achieving precise control.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] An electric lifting controller for agricultural machinery includes a control lever. The lower end of the control lever is provided with two left and right connectors that are snapped together. The control lever includes a shift shaft, the lower end of which extends into the cavity between the left and right connectors.

[0008] Left and right rotating shafts extend vertically outward from the lower end of the rotary shaft, and the left and right rotating shafts are coaxially arranged.

[0009] Mounting holes are provided on both the left and right connectors. Bearings are fitted on both the left and right rotating shafts. The left rotating shaft is rotatably mounted on the mounting hole of the left connector through the bearing, and the right rotating shaft is rotatably mounted on the mounting hole of the right connector through the bearing. An angle sensor is installed at the end of the right rotating shaft.

[0010] Furthermore, the left connector and the right connector are two parts with identical structure and shape.

[0011] Furthermore, the left and right connectors are plastic parts manufactured by injection molding.

[0012] Furthermore, the top of the left and right connectors are provided with actuation grooves, and the actuation shaft moves back and forth within the actuation grooves.

[0013] Furthermore, the bottom end of the pivot extends radially to its left to form a pivot fork, which extends out of the outside of the left connector; the left and right connectors are provided with blocking protrusions on their outer sides, and the shaft segment of the left pivot extending out of the left connector is equipped with a return spring, the first and last ends of the return spring extending downward and clamping the blocking protrusion and the pivot fork.

[0014] Furthermore, the upper ends of the facing inner sides of the left and right connectors are provided with two upper bolt holes, and the lower ends of the facing inner sides of the left and right connectors are provided with two lower bolt holes.

[0015] Furthermore, it also includes an electronic control system, to which the signal line of the angle sensor is connected.

[0016] Furthermore, an operating handle is inserted into the upper end of the dial.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] The rotation angle of the lever shaft is adjusted, and an angle sensor detects the rotation angle. The larger the rotation angle, the faster the agricultural implement can be raised or lowered. The electronic control system converts the continuously changing analog signal from the angle sensor into a digital signal, enabling precise control of the opening of the multi-way valve. This makes the system more intelligent and easier to operate.

[0019] The shift fork moves the first or last end of the return spring, and the blocking protrusion blocks the other end of the return spring, so that the shift shaft can automatically return to its original position after rotation.

Detailed Implementation

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, this utility model provides an electric lifting controller for agricultural machinery, including a control lever 1. The lower end of the control lever 1 is provided with two left connectors 2 and right connectors 3 that are fastened together. The control lever 1 includes a pivot 101, the lower end of which extends into the cavity between the left connector 2 and the right connector 3.

[0029] Left rotating shaft 102 and right rotating shaft 103 extend vertically outward from the left and right sides of the lower end of the pivot shaft 101, and the left rotating shaft 102 and right rotating shaft 103 are coaxially arranged.

[0030] Mounting holes 202 are provided on both the left connector 2 and the right connector 3. Bearings 4 are fitted on both the left rotating shaft 102 and the right rotating shaft 103. The left rotating shaft 102 is rotatably mounted on the mounting hole 202 of the left connector 2 through the bearing 4, and the right rotating shaft 103 is rotatably mounted on the mounting hole 202 of the right connector 3 through the bearing 4. An angle sensor 6 is installed at the end of the right rotating shaft 103.

[0031] Left connector 2 and right connector 3 are two parts with identical structure and shape.

[0032] Furthermore, the left connector 2 and the right connector 3 are plastic parts manufactured by injection molding. Since the left connector 2 and the right connector 3 are two parts with the same structure, only one mold is needed to complete the processing, reducing processing costs.

[0033] The top of the left connector 2 and the right connector 3 are provided with actuation grooves 201. When controlling the agricultural implement, the actuation shaft 101 moves back and forth in the actuation grooves 201.

[0034] The bottom end of the pivot shaft 101 extends radially to its left to form a pivot fork 104, which protrudes outside the left connector 2. A blocking protrusion 203 is provided on the outer side of both the left connector 2 and the right connector 3. A return spring 5 is installed on the shaft segment of the left pivot shaft 102 that extends outside the left connector 2. The head and tail ends of the return spring 5 extend downwards and clamp the blocking protrusion 203 and the pivot fork 104. Figure 2 .

[0035] The left connector 2 and the right connector 3 have two upper bolt holes 204 on their inner upper sides facing each other, and two lower bolt holes 205 on their inner lower sides facing each other. The left connector 2 and the right connector 3 are fixed together by insert bolts in the upper bolt holes 204 and lower bolt holes 205.

[0036] This utility model also includes an electronic control system. The signal line of the angle sensor 6 is connected to the electronic control system. The electronic control system converts the continuously changing analog signal of the angle sensor 6 into a digital signal to precisely control the opening degree of the multi-way valve.

[0037] The upper end of the dial 101 is fitted with a control handle 7, which is used to adjust the rotation angle of the dial 101 by manually moving the control handle 7.

[0038] The specific working principle of this utility model:

[0039] When this invention is installed in the cab, and the implement is not being operated, the deflector shaft 101 is located in the middle position of the deflector groove 201. The rotation angle of the deflector shaft 101 is adjusted by manually moving the control handle 7. The angle sensor 6 detects the rotation angle of the deflector shaft 101; the larger the rotation angle, the faster the implement is raised or lowered. The electronic control system converts the continuously changing analog signal from the angle sensor 6 into a digital signal, enabling precise control of the opening of the multi-way valve. This makes the system more intelligent and easier to operate.

[0040] When the dial shaft 101 rotates, the dial fork 104 moves the first or last end of the return spring 5, and the blocking protrusion 203 blocks the other end of the return spring 5, so that the dial shaft 101 can automatically return to its original position after rotation.
