Problems solved by technology
In addition, most of the subsoilers on the market are integrated, that is, the subsoiler is rigidly connected with the subsoiler. When this subsoiler is operating, when the resistance of a single subsoiler increases, it will affect the overall operation effect and efficiency. , so it is necessary to realize that each subsoiling shovel can self-adjust the size of the subsoiling angle according to the operation resistance during the subsoiling operation

The invention discloses a subsoiler, which comprises a plurality of groups of subsoiler operation units, wherein each group of subsoiler operation unit comprises a hydraulic cylinder and a bionic claw-finger mechanism, and the hydraulic cylinder is hinged to the bionic claw-finger mechanism. The invention also discloses a real-time control system of a subsoiling penetrating angle. The real-time control system of the subsoiling penetrating angle comprises a main controller, a touch screen display, a plurality of controller units, and a plurality of sensor groups. The touch screen display and the main controller are connected by a circuit, and the plurality of controller units are respectively connected with the main controller through the circuit; each controller unit is connected with a corresponding group of sensors, and the sensor groups are arranged on the subsoiler operation units, and comprises a three-position four-way electromagnetic proportional reversing valve, a shaft pin sensor, a subsoiling shovel shaft angle sensor and ultrasonic sensors; the three-position four-way electromagnetic proportional reversing valve is connected with a hydraulic cylinder oil circuit, and theshaft pin sensor is placed at the hinge joint of a hydraulic cylinder and a four-bar mechanism; the subsoiling shovel shaft angle sensor is fixedly arranged on a subsoiling shovel shaft, and the ultrasonic sensors are fixedly arranged at both sides of the subsoiling shovel shaft angle sensor.
Description
Technical field [0001] The invention relates to the technical field of agricultural machinery, and in particular to a system and method for real-time control of the deep loosening angle of entry of a bionic finger-claw mechanism, belonging to the field of deep loosening of soil. Background technique [0002] Soil deep loosening is a key technology of mechanized conservation tillage. It can break the bottom of the plow, improve the soil solid-liquid-gas ratio, enhance soil water storage capacity, promote plant root development, and achieve the purpose of increasing production and income. The soil penetration performance of subsoiler is an important index of subsoiler performance. The entry angle of most subsoilers on the market is fixed, even if it is variable, the range of change is small. The working conditions of deep loosening of soil are complicated, and the specific resistance of soil tillage of different plots is quite different, and the specific resistance of tillage of t...
