Meanwhile, the structure is simple, the production is convenient, the manufacturing cost is low, and the device can be popularized in a large area.

As described above, the cutting saw 220 is disposed on one side of the cutting body 200, and specifically, a mounting portion 230 may protrude from one side of the cutting body 200, the mounting portion 230 may be a metal plate welded to one side of the cutting body 200, the cutting saw 220 includes a driving mechanism 222, an inductive probe and a saw blade 221, the driving mechanism 222 is disposed on the mounting portion 230, a driving shaft of the driving mechanism 222 passes through the mounting portion 230 to be connected with the saw blade 221, and the inductive probe is disposed at an end portion of the driving shaft, protrudes from the saw blade 221, and is electrically connected with the driving mechanism 222. In the cutting process, the sensing probe detects the distance between the saw blade 221 and the ground, when the distance is larger, the stubble remaining height is too high, the height of the saw blade 221 needs to be reduced, so that the stubble remaining height meets the requirement, and when the distance is smaller, the possibility that the saw blade 221 touches the ground exists, and the saw blade 221 is damaged. Therefore, the inductive probe detects the distance between the saw blade 221 and the ground, and the inductive probe controls the driving mechanism 222 to start only when the detected distance value is within a predetermined range, that is, the saw blade 221 starts to rotate to cut the caragana microphylla only when the detected distance value is within the predetermined range, so that the stubble height is prevented from being too high or the saw blade 221 is damaged due to collision with the ground, the reliability of the caragana microphylla cutting device is ensured, and the uniformity of the stubble height is ensured. The predetermined range may be 8 cm to 12 cm.
