Background
Repeated rolling of the soil by tractors and agricultural implements can cause excessive compaction of the soil, forming a hard plough layer at the bottom of the plough layer. The plough bottom layer can prevent the growth and the interpenetration of crop roots, so that the crops can not absorb the moisture and the nutrition of the deep soil layer, the downward seepage of rainwater can be reduced, and the water and soil loss is aggravated. The plough bottom layer can be effectively broken through the deep scarification operation, but the depths of the plough bottom layer in the same field are different due to the difference of the physical properties of the soil and the incomplete consistency of the grinding degree of the tractor and the agricultural implement on the soil; the current subsoiler can only simply adjust the tilling depth and cannot specifically detect the depth of a plough bottom layer; when the plough bottom layer is shallow, the deep scarification depth exceeds the plough bottom layer, which causes overlarge resistance and increased energy consumption; when the plough bottom layer is deeper, the depth of the deep scarification does not reach the depth of the plough bottom layer, so that the plough bottom layer is not broken or is not thoroughly broken.
Because the air, the plough layer and the plough bottom layer have large difference in physical properties and different dielectric constants, the electromagnetic waves can be reflected at the interface of the air and the plough layer and the interface of the plough layer and the plough bottom layer in the transmission process, and the depth of the plough bottom layer can be calculated by recording the transmission time of the electromagnetic waves in the air and the plough layer; and the electromagnetic wave can not be interfered by the mechanical wave generated by the vibration of the subsoiler, so that the depth of the plough bottom layer can be accurately detected.
The invention provides a subsoiler capable of automatically adjusting the ploughing depth based on electromagnetic waves, which can detect the depths of plough bottom layers at different positions in real time, automatically adjust the ploughing depth, thoroughly break the plough bottom layers, and send plough bottom layer depth information to an agricultural machinery management platform, so that references are provided for subsequent soil upgrading work and high-standard farmland construction.
