The ground processed by the milling machine can be a road surface, a stone ground, a forest ground or a soil ground and the like.
Since milling cutters wear significantly after a certain period of operation, when the cutting head is worn to a certain extent, it must be replaced in order not only to maintain the power and the quality of the milling pattern of the ground milling machine, but also to avoid damage to other machine components. The operation of replacing the cutter assemblies typically requires the operator to interrupt the operation of the milling machine and shut down the milling machine, and then visually inspect the wear of the cutters. This type of wear check is not only time and labor consuming, but also requires an interruption in operation, which can affect the efficiency of the operation of the equipment.
Based on the above problems, the present invention provides a milling cutter detection method, which can perform wear detection on the milling cutter 100 without affecting the working efficiency of the milling machine, and can reduce the difficulty of detection.

and if the maximum pressure value and the minimum pressure value exceed the preset acting force range, outputting an abnormal working signal.
Wherein the step of outputting the abnormal operation signal includes: and outputting an alarm signal to the alarm to alarm the alarm.
Based on the above steps, in this embodiment, the preset acting force range includes a first end value and a second end value, and the first end value is greater than the second end value;
the first end is the product of the average of the maximum pressure values of all the cutting heads 110 and the scaling factor α, and the second end is the product of the average of the minimum pressure values of all the cutting heads 110 and the scaling factor β.

Thus, based on the above manner, in the detection process, the average value F of the maximum pressure values of all the cutter heads 110 in the same rotation period in the initial construction stage is detectedmax1And the average value F of the minimum pressure valuesmin1Then, the first terminal α F is obtainedmax1And a second end value β Fmin1；
By detecting the maximum pressure value F of all the cutter heads 110 in the same rotation period of the construction stageA2maxAnd a minimum pressure value FA2minRespectively connected with the first terminal α Fmax1And a second end value β Fmin1Comparing;

It should be noted that, when the proportionality coefficient α and the proportionality coefficient β are set, the reference value may be obtained through experiments or experience, for example, the reference value is selected to be 105% to 120%.
Referring to fig. 3, fig. 3 illustrates a structure of a milling cutter detecting device according to an embodiment of the present invention; based on the milling cutter detection method, the embodiment provides a milling cutter detection device 200, which includes a detection member 210 and a controller.
