[0024] The output end of the motor 10 is fixedly installed with the worm 8, the worm 8 movably penetrates one side of the protection box 9, and the worm 8 is rotatably connected with the protection box 9 through the bearing seat, the other end of the rotating shaft 2 is fixedly installed with the worm wheel 7, and the worm 8 is engaged with the worm wheel 7.

[0025] In the above technical scheme, specifically, the furrower for agricultural machinery can be fixedly installed on the traction equipment through high-strength bolts during use, and the shell 1 can be lifted and lowered through the lifting system on the traction equipment, such as the hydraulic lifting device of a tractor, although it is not explicitly mentioned in the claims, but it belongs to a conventional technical means, which can realize the lifting and lowering of the shell 1. When the furrower body 6 is damaged during use, the shell 1 is lifted by the lifting system on the traction equipment, so that the furrower body 6 is separated from the ground, and then the motor 10 can be started. The motor 10 drives the worm 8 to rotate, the worm 8 drives the worm wheel 7 to rotate, the worm wheel 7 drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the sleeve rod 4 to rotate, the sleeve rod 4 drives the damaged furrower body 6 to rotate upward through the movable rod 5, so that the damaged furrower body 6 is rotated to the inside of the shell 1, and at the same time, the rotating shaft 2 drives the intact furrower body 6 to rotate through the sleeve rod 4 and the movable rod 5, so that the intact furrower body 6 is located below the shell 1, thereby completing replacement. Then, the shell 1 is lowered again through the lifting system on the traction equipment, so that the intact furrower body 6 is in contact with the ground, and the trenching operation is continuously performed. Through the above structure, a backup furrower is designed. When the furrower is damaged during use, the damaged furrower can be directly rotated to the inside of the shell 1, and the intact furrower in the shell 1 can be directly rotated below the shell 1, thereby completing replacement and continuously performing trenching operation. After trenching is completed, the damaged furrower is disassembled and maintained, thereby ensuring the continuity of trenching, improving the trenching efficiency, and solving the problem that the existing furrower needs to be disassembled and replaced after being damaged, thereby greatly affecting the continuity of trenching and the trenching efficiency.

[0026] Further, the number of furrower bodies 6 and sleeve rods 4 is four, and the top of the machine box 11 is provided with a heat dissipation opening;

[0027] Wherein, by setting the case 11, can play a certain protective effect on the motor 10.
