Tractor tilling depth multi-parameter combined automatic adjusting system

The utility model discloses a tractor tilling depth multi-parameter combined automatic adjusting system which comprises the following steps: before tractor tilling, initializing the system, setting tilling parameters, and selecting weighting coefficients; during farming, the system judges whether to perform joint automatic adjustment or not and then calculates a real-time slip ratio according to afeedback signal of the sensor; when the slip ratio is within a set threshold, the system judges whether the value of the weighting coefficient is reasonable or not, if the value of the weighting coefficient exceeds the set interval, adjustment needs to be input again or quit, and otherwise, the system distributes a feedback signal proportion according to the value of the weighting coefficient andoutputs a corresponding tilling depth adjustment mode; in the farming process, if the slip ratio exceeds a set threshold, the system directly adjusts the slip ratio until the slip ratio is adjusted to be within the set thresh
