Problems solved by technology
This method has a large workload, low efficiency, and manual removal of soil is highly subjective, which may easily cause inaccurate furrow detection; at the same time, this method cannot continuously measure the profile shape of the furrow, so it cannot be used for deep loosening operations. The resulting furrow shape has a three-dimensional intuitive understanding

The invention discloses a three-dimensional subsoiling operation quality detection system, and belongs to the technical field of agricultural machinery. In the invention, a transmitter mounting plateof an electromagnetic wave transmitting device and a receiver mounting plate of an electromagnetic wave receiving device are arranged in parallel at the front and rear; the transmitter mounting plateand the receiver mounting plate are located between a middle cross beam and a rear cross beam of a rack I of a subsoiler, and both ends of the transmitter mounting plate and the receiver mounting plate are fixedly connected with inner surfaces of a left longitudinal beam and a right longitudinal beam; and a microcomputer communicates with a communication interface I in the electromagnetic wave receiving device and a communication interface II of the electromagnetic wave transmitting device, separately. According to the invention, multiple electromagnetic wave beams are used to detect the shapeand position of a furrow profile, the detection process does not require manual removal of loose soil, therefore, the accuracy and efficiency of measurement are both higher than those by conventionalmethods, and a three-dimensional image of the furrow can be obtained quickly through processing by the microcomputer such that the tilling depth and subsoiling disturbed area of the subsoiling operations are obtained to provide data support for the evaluation of subsoiling operation quality, the operation efficiency of the subsoiler, and the allowance for subsoiling operations.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a three-dimensional subsoiling operation quality detection system. Background technique [0002] The subsoiler can loosen the soil, break the bottom layer of the plow, promote the growth of the root system of the crop, and enable the root system of the crop to absorb nutrients and water in the inner soil layer, thereby increasing production; at the same time, the subsoiler can reduce surface runoff during rainfall and slow down soil erosion . The furrow formed by the subsoiling operation (the interface between the loosened and unbroken soil after subsoiling) can not only reflect the plowing depth of the subsoiling operation, but also reflect the subsoiling area. Therefore, measuring the shape and area of the furrow after subsoiling operation is of great significance to the evaluation of subsoiling operation quality and performance of subsoiling machi...
