Please refer to FIG. 1 to FIG. 3 again, the power mechanism 400 is disposed on the vehicle frame 100 . The power mechanism 400 includes an engine 410 , a battery 420 and a starter 430 . The output shaft of the engine 410 is provided with an output shaft rotating wheel 440 and an electromagnetic clutch 450 . The engine 410 is arranged on the vehicle frame 100 through an engine base (not shown in the figure), which acts as a shock absorber for the engine 410 . The battery 420 is used for powering the starter 430 and the electromagnetic clutch 450 , and the electromagnetic clutch 450 is connected with the cutting shaft rotating wheel 240 through the conveyor belt 460 . The energization of the electromagnetic clutch 450 controls the rotation of the cutting shaft rotating wheel 240 . The output shaft rotating wheel 440 can be an output shaft pulley, which utilizes the characteristics of belt drive to allow overload and slippage.

When the electromagnetic clutch 450 is energized, the power of the engine 410 is transmitted to the electromagnetic clutch 450 through its output shaft, and the electromagnetic clutch 450 is transmitted to the cutting shaft rotating wheel 240 through the conveyor belt, and the cutting shaft rotating wheel 240 drives the cutting shaft 210 to rotate and then drives the cutting cutter head 220 and the cutting teeth 230 on it rotate to cut the stump. The power output by the engine 410 is transmitted to the cutting disc 220 through a belt transmission, wherein no deceleration is required. When the electromagnetic clutch 450 is powered off, the power of the engine 410 cannot be transmitted to the cutting shaft rotating wheel 240 through the electromagnetic clutch 450, so the cutting cutterhead 220 and the cutting teeth 230 thereon do not rotate.

Please also refer to FIG. 7 , the control mechanism 500 is disposed at the rear end of the vehicle frame 100 . The control mechanism 500 includes a control handle 510, a gear handle 520, a brake 530, an engine throttle 540, and a damper 550. The control handle 510 is used to control the steering, the gear handle 520 is used to control the forward or backward movement of the traveling mechanism 300, and the brake 530 is used to control the walking. Parking of the mechanism 300 , the engine throttle 540 and the damper 550 are used to control the operation of the engine 410 . The control handle 510 includes a bracket 511 and an operating handle 512 arranged on the bracket 511. The bracket 511 is arranged on the vehicle frame 100, and the bracket 511 and the vehicle frame 100 are arranged at a certain angle. The two ends of the rack 100 are safe to operate.

The hydraulic pump 320 is connected with the output shaft rotating wheel 440, and the gear handle 520 controls the hydraulic pump 320 to control the forward and backward movement of the wheels 340. The brake 530 achieves the purpose of parking by limiting the movement of the differential 310. The engine 410 is connected with the hydraulic pump 320 of the traveling mechanism 300 through a belt transmission, and provides power for the hydraulic pump 320 to drive the wheels 340 to rotate to realize the self-propelled function. The hydraulic pump 320 realizes the function of deceleration on the one hand, and on the other hand also provides powerful torque for the wheels 340, so that the vertical disc root cleaning machine 10 can climb up to a steep slope of 30 degrees. Simultaneously, hydraulic pump 320 and differential gear 310 are designed as an integrated structure, and the width of the root-cutting machine can be reduced, so that the root-cutting machine can pass through the narrowest narrow channel with a width of 800mm, which facilitates the operation of the root-cutting machine in the forest area.

The power of the above-mentioned vertical disc type root cutting machine 10 is provided by the engine 410, which provides power for the cutting cutter head 220 and the hydraulic pump 320 respectively through the conveyor belt. The main cutting motion is the high-speed rotation of the cutting cutter head 220 and the cutting teeth 230, and the feeding The control handle 510 controls the translation and lifting of the cutting cutter head 220 to realize the cutting of the tree stump and the surrounding soil. At the same time, the power transmitted from the engine 410 to the hydraulic pump 320 and the differential 310 realizes the self-propelled operation of the vertical disc root removal machine 10. Features.

Specifically: start the starter 430, the starter 430 drives the engine 410 to work, the vertical disc type root cleaning machine 10 is controlled by the control handle 510 and the gear handle 520 to open to the cleaning site, the engine 410 provides power for the cutting shaft 210 by the conveyor belt, and the electromagnetic The energization of the clutch 450 determines whether to drive the cutting shaft 210 to rotate. When the cutting shaft 210 rotates, it drives the cutting cutter head 220 to rotate, and then drives the cutting teeth 230 on it to rotate. With the wheel 340 as the fulcrum, swing the control handle 510 left and right to make the vehicle frame 100 rotate. Swing, drive the cutting cutterhead 220 that links to each other with vehicle frame 100 to swing and mill stump with this, then control handle 510 is moved upwards and cutting cutterhead 220 moves down and cuts the stump deeply and cuts off the soil around the stump. The cutting root cleaning device combines mechanical and manual operations well. The main cutting movement is completed by the mechanical part, and the feeding movement is controlled by manual operation, so that the mechanical structure can be simplified as much as possible. The root pulling machine and gear pushing machine are much smaller, and the power is much smaller (18kw) than these large machines, and the damage to the ground is small, avoiding soil erosion.

Since the milling method needs to cut back and forth repeatedly, the roots cannot be removed at one time, so the work efficiency is much lower than that of large machines. This vertical disc type root cutting machine 10 is the cutting of the roots and the soil. After the cutting is completed, an approximately 500mm deep soil pit is left on the ground, and the broken soil and wood chips are left on the ground. During the process of loosening the soil, the sawdust left behind can also act as a fertilizer.

The above-mentioned embodiments only express several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but should not be construed as limiting the patent scope of the invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
