[0006] Knob switch: adjust the gear and send corresponding signals to the main controller;

[0007] Main controller: receive the signals of the knob switch, the lifting switch, and the reset switch, and send corresponding working signals to the execution device;

[0008] Execution device: used for controlling the lifting or lowering of the cutting platform;

[0009] Lifting switch: send signals to the main controller to lift the cutting platform to the highest;

[0010] Reset switch: send signals to the main controller to restore the cutting platform to the predetermined position.

[0011] Further, the lifting mechanism comprises a connecting rod, one end of which is hinged to the rack, and the other end is hinged to the cutting platform.

[0012] Further, the execution device is an electric telescopic push rod, the base of which is hinged to the rack, and the head of the telescopic rod part is hinged to the cutting platform.

[0013] Further, the knob switch comprises seven gears.

[0014] Further, the connecting rod is made of metal.

[0015] Further, the metal material is steel.

[0016] Beneficial effects: compared with the prior art, the utility model has the following advantages:

[0017] Very easy and convenient: only need to rotate the knob to the required height gear, the cutting platform can be adjusted to the required height; one-key lifting and one-key resetting can quickly switch the two special positions of the cutting platform, greatly reducing the manual operation.

[0018] Driving operation: when the cutting platform encounters a situation that needs to be lifted to pass, one-key lifting of the cutting platform to the highest point; after passing the section, press the reset button, the cutting platform returns to the height before lifting, the whole process does not need to stop.

[0023] In order to deepen the understanding of the utility model, the utility model will be further described in combination with examples and drawings below, the examples are only used to explain the utility model, and do not constitute the limitation to the protection scope of the utility model.

[0024] As shown in Figures 1-2 Connecting rod 1, cutting platform 2, electric telescopic push rod 3;

[0025] A cutting platform lifting mechanism based on an electrical control system, comprising a cutting platform 2, a lifting mechanism, an execution device, an electrical control system, the electrical control system comprises:

[0026] Knob switch: adjust the gear and send the corresponding signal to the main controller;

[0027] Main controller: receiving the signals of knob switch, lifting switch and reset switch, sending the corresponding working signals to the execution device;

[0028] Execution device: used for controlling the lifting or lowering of the cutting platform 2;

[0029] Lifting switch: sending the signal to the main controller, so that the cutting platform 2 is lifted to the highest;

[0030] Reset switch: send signal to main controller, make header 2 return to predetermined position.

[0031] In this embodiment, the lifting mechanism includes connecting rod 1, one end of which is hinged to the frame, and the other end is hinged to the header 2.

[0032] In this embodiment, the execution device is an electric telescopic push rod 3, the base of which is hinged to the frame, and the head of the telescopic rod part is hinged to the header 2.

[0033] In this embodiment, the knob switch includes seven gears.

[0034] In this embodiment, the connecting rod 1 is made of metal.

[0035] In this embodiment, the metal material is steel.

[0036] Instructions:

[0037] Header 2 height adjustment:

[0038] The seven gears of the knob switch represent seven different heights of the header 2, which correspond to different strokes of the electric push rod. When the mower is working, different gears can be selected by rotating the knob switch, and the electric push rod will change its length according to the received instructions to change the working height of the header 2.

[0039] Header 2 obstacle avoidance:

[0040] When the mower encounters a section that cannot be passed at the current working height of the header 2 during travel, the lift switch can be pressed. At this time, the electric push rod will be retracted to the shortest, i.e. the header 2 will be lifted to the highest height, and the header 2 can pass through the section smoothly without the need to stop and operate.

[0041] Header 2 reset:

[0042] After the header 2 is lifted through a section, the reset switch is pressed, and the electric push rod will return to the length before lifting, and the header 2 will return to the height before lifting, and quickly return to the normal working state. This process also does not require stopping and operating.

[0043] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
