[0020] Figure 1 It is the whole flow chart of a silage machine whetstone device control system in the utility model. CONCRETE IMPLEMENTING METHOD

[0021] It needs to be explained that the embodiment in the application and the feature in the embodiment can be combined mutually in the case of not conflicting.The utility model will be explained in detail below with reference to the drawings and combining embodiment.

[0022] It needs to be pointed out that all technical and scientific terms used in the application have the same meaning with the person ordinarily skilled in the art in the application, unless otherwise indicated.

[0023] In the utility model, the orientation such as "up, down" used in the case where not making opposite statement is usually for the direction shown in the drawing, or for the vertical, perpendicular or gravity direction; similarly, for the convenience of understanding and description, "left, right" is usually for the left, right shown in the drawing; "inner, outer" refers to the inner, outer relative to the contour of each component itself, but the above orientation words are not used to limit the utility model.

[0024] Please refer to Figure 1 A silage machine knife grinding device control system, including the cab, the cab is provided with the whole vehicle controller, the whole vehicle controller includes power module, drive module, communication module and signal acquisition and processing module, the power module is connected with power input signal, the signal acquisition and processing module is connected with switch input signal module and hydraulic signal input module;The drive module includes manual execution module and automatic execution module, which respectively includes electromagnetic valve group, electric push rod and oil cylinder, the self-execution module includes automatic mode switch;The power module includes knife grinding power switch;The communication module is connected with display screen and ECU module;The operating switch of control knife shell and knife stone is installed in and outside the cab respectively;The cab outside is provided with knife grinding indicator light and alarm light;The emergency stop button is arranged in and outside the cab.

[0025] The control logic of the knife grinding device is integrated in the whole vehicle controller, the engine speed is collected through the bus, the knife grinding power switch is set on the operation box, the operating switch of control knife shell and knife stone is installed in and outside the cab, and the knife grinding indicator light and alarm light are arranged at the obvious position outside the cab, etc., the execution device is electric push rod and electromagnetic valve, and the working principle is as follows:

[0026] Knife shell control:

[0027] Manual mode: turn on the knife grinding power switch, the engine speed is automatically reduced to the system pre-set speed, and keeps constant speed operation, ensures the grinding speed, and the state indicator light on the display screen and the body outside indicator light are turned on. Under the condition that the knife grinding power is valid, click the knife shell opening button, the electric push rod motor automatically turns the knife shell up to open, the double motor automatically follows and synchronizes, and after completely opening, automatically power off or stop according to the pre-set opening, the position sensor in the motor automatically calculates. After grinding, click the knife shell closing button, the push rod automatically retracts, and the knife shell is completely closed after power off.

[0028] Knife grinding control (operation is valid after the knife shell is opened, the system automatically remembers)

[0029] Manual mode: click the right row of knife stone button, the right row electromagnetic valve works, the oil cylinder extends, long press continues to run, stop when hand is released, and automatically power off when reaching the limit. Click the left row of knife stone button, the left row electromagnetic valve works, the oil cylinder retracts, long press continues to run, stop when hand is released, and automatically power off when reaching the limit. The knife stone can reciprocate at any position in the grinding process, which is not constrained by the limit switch.

[0030] Automatic mode

[0031] After the automatic mode switch is triggered, the display screen and the external sharpener indicator light on the vehicle body are lit, the sharpener shell is automatically opened first, after being fully opened, the grinding stone starts to run from left to right, reaches the right limit, automatically stops, returns automatically after 2 seconds, reaches the left limit, and the right limit logic is executed in the same way, so as to reciprocate. If the automatic mode switch is turned off during the grinding process, the grinding stone will automatically return to the left limit position and stop moving, and the sharpener shell will automatically close after 2 seconds.

[0032] Memory and alarm function

[0033] The system has a full memory function, that is, even if the grinding stone is already at the initial position at the initial power-on stage, the left movement is still performed for 3-5 seconds, so that there is no hidden danger when the sharpener shell is opened, and no matter whether the sharpener shell is opened or the grinding process is performed, the system automatically monitors and alarms in case of abnormal engine speed, abnormal hydraulic system pressure, or abnormal limit switch.

[0034] Emergency stop button, no matter whether the sharpener shell is in the opening process or the grinding process, once the system is abnormal, the emergency stop button (which is arranged on the vehicle body and in the cab) is pressed, the system stops working, and the engine is turned off.

[0035] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
