[0027] The principles and characteristics of the utility model are described below in combination with embodiments; the examples are only used to explain the utility model; and are not used to limit the scope of the utility model.

[0028] A machine sawing device special for sand shrub stubble cutting, comprising a power output device 100, a torque sensor 200, a reversing box 300 and a cutting assembly 400.

[0029] The power output device 100 is a hydraulic piston pump, which is used for the suction and discharge of hydraulic oil in the hydraulic system and provides power for the whole sawing device. One end of the power output device 100 is provided with a self-rotating first power shaft 101, which is the output end of the power output device 100. The torque sensor 200 is used for measuring the torque transmitted by the sawing system, and the pressure in the hydraulic system is adjusted in time through monitoring the torque, so as to ensure the sawing quality. Specifically, the torque sensor 200 is connected with a coupling 201 at both ends, one end of the coupling 201 is connected with the first power shaft 101, and the other end of the coupling 201 is connected with the reversing box 300. The reversing box 300 has a second power shaft 301 and a third power shaft 302 which are perpendicular to each other, so as to attach the cutting assembly 400 to the third power shaft 302. Figure 1 The second power shaft 301 is in a horizontal state, the third power shaft 302 is in a vertical state, and the second power shaft 301 is connected with the coupling 201 on one side of the torque sensor 200. The cutting assembly 400 is connected with the third power shaft 302.

[0030] The cutting assembly 400 comprises a fourth power shaft 401, a fifth power shaft 402, a sawing assembly 403 and a protective cover 404. The fourth power shaft 401 is cylindrical, and the fourth power shaft 401 is fixed relative to the third power shaft 302, and the third power shaft 302 drives the fourth power shaft 401 to rotate. The fourth power shaft 401 is cylindrical, and the fifth power shaft 402 extends into the fourth power shaft 401 and is rotatably connected to the fourth power shaft 401 through a bearing. The sawing assembly 403 is connected to the fourth power shaft 401, and the protective cover 404 is connected to the fifth power shaft 402. Because the fourth power shaft 401 and the fifth power shaft 402 can rotate relative to each other, the sawing assembly 402 and the protective cover 404 are rotatably connected. The protective cover 404 is arranged on the side of the cutting assembly 400 facing the stubble opening, and is fixed relative to the fifth power shaft 402 through fasteners. Specifically, the sawing assembly 403 comprises a first chuck 4031, a second chuck 4032 and a circular saw blade 4033. The first chuck 4031 is fixed relative to the fourth power shaft 401, the second chuck 4032 is fixed relative to the first chuck 4031 through fasteners, and the second chuck 4032 is convenient to replace. The protective cover 404 is circumferentially fixed to the second chuck 4032 through a pin shaft 4034, and the pin shaft 4034 is a split pin. When the protective cover 404 needs to be disassembled, the split pin needs to be used to fix the protective cover 404 relative to the second chuck 4032.

[0031] The above merely describes the preferred embodiments of the present application; is not used to limit the present application; any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application; should be included in the protection scope of the present application.
