Example Embodiment

[0027] The following describes the present invention in further detail with reference to the embodiments and the drawings, but the implementation of the present invention is not limited thereto.

[0028] An active leveling system for a diamond-shaped four-wheel field cultivator includes a sensor, a controller and an actuator. The sensors include three-axis acceleration sensor, gyroscope I and gyroscope II; the controller includes A / D, D / A converters and single-chip microcomputer; the actuator includes solenoid valves and hydraulic cylinders. The three-axis acceleration sensor, gyroscope I and gyroscope II are respectively electrically connected with the single-chip microcomputer; the single-chip microcomputer is electrically connected with the actuator, and a control signal is sent to control the on-off time of the battery valve. The single-chip microcomputer presets the preset angle value.

[0029] The three-axis acceleration sensor can collect the acceleration of the diamond-sha...

Abstract

The invention relates to a rhombus four-wheel cultivator active leveling system. The system comprises a sensor, a controller and an actuator. The sensor comprises a three-axis acceleration sensor usedfor real-time measurement of a running acceleration of a rhombus four-wheel cultivator, and a gyroscope I and a gyroscope II used for measuring a running angular velocity of the rhombus four-wheel cultivator in real time respectively. The three-axis acceleration sensor, the gyroscope I and the gyroscope II are eclectically connected to the controller. The controller is electrically connected to the actuator. By using the system, an automation degree of the rhombus four-wheel cultivator is increased; a working condition is effectively improved; a rollover potential safety hazard during operation is reduced; and stability and comfortableness of the rhombus four-wheel cultivator during operation are increased. The invention also relates to a rhombus four-wheel cultivator active leveling method. In a leveling process, an angular velocity signal is collected to calculate an attitude angle II of the rhombus four-wheel cultivator so as to make negative feedback judgment, and accuracy of leveling is improved.

Description

technical field [0001] The invention relates to the technical control field of agricultural machinery, in particular to an active leveling system and method for a diamond-shaped four-wheel cultivator. Background technique [0002] At present, in the process of mechanized plant protection technology for high-stalk crops such as sugarcane and corn, cultivating soil, weeding, and fertilizing are important links in the production process. The diamond-shaped four-wheel cultivator not only has the characteristics of a general cultivator that can complete soil loosening, weeding, soil cultivation and fertilization at one time, but also because of its unique mechanical structure, it is more suitable for high-stalk crops such as sugarcane and corn, and has become a high-stalk cultivator. The main development direction of crop mechanized management. However, at present, the operation automation level of domestic diamond-shaped four-wheel cultivators is low, and there are also problem...
