[0058] Working principle: the operator pushes the seat 1 through the handrail 2, and moves the device to the vicinity of the area where the spiny-calyx nightshade grows with the help of the universal wheels 3 around the bottom of the seat 1. At the same time, an appropriate amount of water is injected into the water tank 5 through the water injection pipe at the upper end of the water tank 5 to prepare for the subsequent water spraying operation. When the working position is reached, the rotating motor 9 on one side of the outer end of the connecting box 4 is started, and the rotating motor 9 drives the screw 10 to rotate. Since the screw 10 is threadedly connected to the sliders 11 on both sides inside the connecting box 4, and the slider 11 is restricted by the inner wall of the connecting box 4 and can only move in a straight line, as the screw 10 rotates, the slider 11 will move in a straight line toward or away from the screw 10. The movement of the slider 11 drives the support rods 12 hinged on both sides thereof to change their angles, thereby pushing the moving plate 13 to move up and down, and the guide rod 14 at the lower end of the moving plate 13 slides up and down in the channel inside the seat 1 to ensure that the moving plate 13 Stable lifting to avoid deviation or shaking. When the moving plate 13 descends, the pushing claw 15 installed at the lower end of the guide rod 14 gradually approaches the ground until it touches the stem of the spiny calyx nightshade and pushes it down, making it in a state convenient for subsequent root cutting and removal. At the same time or after the lifting device pushes the spiny calyx nightshade down, the rotating motor 29 at the upper end of the protective box 6 is started, and the rotating motor 29 drives the rotating rod 17 to rotate, and the tapered toothed disc 18 at the outer end of the rotating rod 17 also rotates accordingly. The tapered toothed disc 18 is meshed with the tapered toothed disc 23 inside the protective box 6, thereby driving the rotating rod 22 to rotate, and the rotating shaft 1 24 at the rear end of the rotating rod 22 rotates, and transmits power to the rotating shaft 27 through the transmission crawler 25. The rotating shaft 27 drives the rotating rod 3 26 to rotate, and finally the fan blade 28 The high-speed rotation generates a strong airflow to blow the weed debris and dust generated during the cutting process away from the working area to prevent them from affecting the cutting operation and causing blockage to the equipment. At the same time, the driving toothed disc 19 at the lower end of the rotating rod 17 rotates with the rotation of the rotating rod 17, and the driving toothed disc 19 drives the knife-toothed crawler 20 to circulate. Under the joint action of the driving toothed disc 19 and the auxiliary toothed disc 21, the knife-toothed crawler 20 maintains a stable rotation state, and the knife teeth thereon quickly and efficiently cut the roots of the overturned spiny calyx nightshade grass, separate the roots from the soil, and achieve thorough removal of the spiny calyx nightshade grass. During the working process of the cleaning component, the booster water pump 7 is started, and the water in the water tank 5 is sucked and pressurized through the connecting pipe under the action of the booster water pump 7, and then transported to the nozzle 16 through the water pipe 8. The nozzle 16 The high-pressure water jet is sprayed onto the roots of Solanum serrata and the surrounding soil. The main functions of the water jet are as follows: First, it makes the soil moist and soft.First, it can reduce the resistance of the blade track 20 when cutting the root, reduce the energy consumption and wear of the equipment, and improve the cutting efficiency; second, it can suppress the dust generated during the cutting process, improve the working environment, and avoid the dust from causing harm to the health of operators; third, it can wash away the soil on the roots and leaves, making it easier to clean and transport the cut weeds, and also help prevent the weed seeds from spreading and growing again with the scattering of soil.
