Problems solved by technology
In actual work, especially when the subsoiler is subjected to uneven resistance from the ground, its operation quality is often not up to standard. In short, the existing subsoiler cannot automatically adjust its work according to the height fluctuation of the ground Height, to achieve fixed depth loosening

The subsoiler leveling device and its electric control system include a fixed frame mounted on the subsoiler, a connecting bracket and ground contact wheels. The normally open switch SB4 for the rising of the working head of the subsoiler and the normally open switch SB5 for controlling the descending of the working head of the subsoiler, the normally open switch SB4 and the normally open switch SB5 are respectively elastically connected between the fixing frame and the connecting bracket During the period, the normally open switch SB4 is automatically closed with the upward swing of the connecting bracket to control the rise of the working head of the subsoiler, and the normally open switch SB5 is automatically closed with the downward swing of the connecting bracket to control the working head of the subsoiler. decline. The invention automatically adjusts the height of the working head of the subsoiler according to the height fluctuation of the ground, realizes automatic leveling, achieves the purpose of fixed depth loosening, and improves the soil adaptability, operation quality and practicability of the subsoiler. The invention also provides a method for adjusting the subsoiling depth of the subsoiler and the subsoiler.
Description
technical field [0001] The invention relates to a leveling device of a subsoiler and an electric control system thereof, which are used for automatically adjusting the height of the working head of the subsoiler when the cultivated ground is undulating, so as to achieve the purpose of stabilizing the soil at a fixed depth. The invention also relates to a method for adjusting the subsoiling depth of the subsoiler and the subsoiler. Background technique [0002] Mechanical subsoiling refers to the mechanized technology of using different power machinery to complete the subsoiling operation of farmland or orchard. The purpose of mechanical subsoiling is to loosen the soil, break the bottom of the plow, and increase the speed and quantity of rainwater infiltration. Reduce runoff and reduce water evaporation loss. Because mechanical subsoiling only loosens the soil and does not turn the soil, the soil in the plow layer will not be disturbed after operation, and the amount of soil...
