[0033] When the tiller is running, the staff first pushes the push-pull positioner 22, and pushes the second clutch 29 to move forward under the guidance of the spline shaft 27 through the push-pull positioner 22, until the helical teeth on one side of the second clutch 29 are attached to the helical teeth on one side of the first clutch 12, and then the staff starts the engine 2, and the output shaft of the engine 2 drives the transmission wheel 17 to rotate through the transmission belt, thereby driving the input end of the gearbox 3 on the side of the transmission wheel 17 to rotate, and the input end of the gearbox 3 drives the first clutch 12 to rotate on the outer wall of the fixed sleeve 15 through the transmission chain. At this time, the second clutch 29 rotates under the drive of the first clutch 12, thereby driving the spline shaft 27 on the inner wall to rotate, and transmitting power to the other end of the spline shaft 27 and the rotating rod 14 at the power input end of the arc cutter ruler 13, thereby controlling the movement and stop of the arc cutter ruler 13;

[0034] When the engine 2 inputs power into the gearbox 3 through the transmission wheel 17, the output shaft of the gearbox 3 will drive the first transmission gear 5 to rotate, thereby driving the second transmission gear 41 to rotate through the transmission chain. When the second transmission gear 41 rotates, it will drive the transmission shaft 24 on the inner wall to rotate, thereby driving the walking mechanism set on the outer wall of the transmission shaft 24 to operate, driving the scarifier to move forward as a whole to scarify the ginseng bed;

[0035] When the staff needs to adjust the forward direction of the tiller, first the staff pushes the push-pull rod 8 clockwise backward. At this time, the push-pull rod 8 will drive the support shaft 35 fixed on the outer wall to rotate downward, thereby pushing the tray 39 to move into the soil on the ginseng bed through the support rod 36 on the outer wall of the support shaft 35, thereby supporting the entire tiller through the downward rotating support rod 36. Since the tray 39 is movably connected to the support rod 36 through the fixed screw 37 and the connecting frame 38, the staff can now hold the push-pull rod 8 with one hand and rotate the tiller with the other hand to conveniently adjust the direction of the tiller, and then turn the push-pull rod 8 back counterclockwise to allow the walking mechanism set on both sides of the transmission shaft 24 to touch the ground again, and then continue to drive the tiller to move in the adjusted direction to loosen the soil, allowing the staff to easily and quickly adjust the moving direction of the tiller, thereby improving the loosening efficiency.

[0036] like Figure 1-4 As shown, the walking mechanism includes a second wheel 23, a connecting sleeve 42, a telescopic rod 30, a first wheel 19, a support expansion spring and a crawler track 20, the telescopic rod 30 is welded to the inner walls of both sides of the mounting frame 21, the support expansion spring is arranged on the inner wall of the mounting frame 21, the connecting sleeve 42 is connected to the inner wall of one side of the mounting frame 21 through the telescopic rod 30, the transmission shaft 24 is rotatably connected to the inner wall of the connecting sleeve 42, the first wheel 19 is connected to the inner wall of the mounting frame 21 through the support expansion spring, and the second wheel 23 is fixed to the outer wall of the transmission shaft 24;

[0037] When the transmission shaft 24 rotates driven by the second transmission gear 41, it will drive the track 20 on the outer wall to rotate under the guidance of the first wheel 19 through the second wheel 23, thereby driving the tiller 20 to move forward. When the track 20 is pressed on obstacles such as stones and soil or travels on uneven ground, the compressed first wheel 19 will push the supporting expansion spring on the inner wall of the mounting frame 21 to contract, so that the first wheel 19 will contract toward the inner wall of the mounting frame 21 when encountering an impact, and cushion the track 20, thereby effectively protecting the walking mechanism composed of the second wheel 23, the track 20 and the first wheel 19, and improving the service life of the walking mechanism.

[0038] like Figure 3As shown, the outer wall of the support frame 9 is rotatably connected to the third push rod 34, the outer wall of the third push rod 34 is rotatably connected to the second push rod 33, the outer wall of one side of the second push rod 33 is rotatably connected to the outer wall of the support shaft 35, the outer wall of one side of the second push rod 33 is rotatably connected to the first push rod 32, the outer wall of the chassis 1 is fixed to the second support frame 18, the outer wall of the second support frame 18 is fixed to the connecting rod 4, the outer wall of the connecting rod 4 is fixed to the tool holder depth adjuster, the tool holder depth adjuster includes a rotating positioning rod 6 and a connecting seat 7, the connecting seat 7 is fixed to the outer wall of the connecting rod 4, and the first push rod 32 is slidably connected to the connecting seat 7 On the internal tooth connection hole, an arc-shaped rack plate is opened on the outer wall of the first push rod 32, and the arc-shaped rack plate is meshed with the rotating shaft of the inner wall of the connecting seat 7 through a gear.

[0039] like Figure 4 As shown, a reinforcing shaft stabilizing frame 40 is fixed to the outer wall of the bottom of the chassis 1 , and the transmission shaft 24 is rotatably connected to the inner wall of the reinforcing shaft stabilizing frame 40 ; the reinforcing shaft stabilizing frame 40 can support and guide the transmission shaft 24 .

[0041] like Figure 1 As shown, a connecting rod 10 is fixed to the inner wall of the support frame 9; the connecting rod 10 can improve the overall stability of the support frame 9, so that the tiller can perform the tilling operation more stably.

[0042] Working principle: When the tiller is running, the staff first pushes the push-pull positioner 22, and pushes the second clutch 29 to move forward under the guidance of the spline shaft 27 through the push-pull positioner 22, until the helical teeth on one side of the second clutch 29 are attached to the helical teeth on one side of the first clutch 12, and then the staff starts the engine 2, and the output shaft of the engine 2 drives the transmission wheel 17 to rotate through the transmission belt, thereby driving the input end of the gearbox 3 on the side of the transmission wheel 17 to rotate, and the input end of the gearbox 3 drives the first clutch 12 to rotate on the outer wall of the fixed sleeve 15 through the transmission chain. At this time, the second clutch 29 rotates under the drive of the first clutch 12, thereby driving the spline shaft 27 on the inner wall to rotate, and when the transmission wheel 17 rotates, it will drive the fixed sleeve 15 on the inner wall of the first clutch 12 to rotate, and when the fixed sleeve 15 rotates, it will drive the rotating rod 14 connected to the inner wall of the support frame 9 to rotate through the transmission chain, so that the soil is loosened through the multiple arc-shaped cutter rulers 13 fixed on the outer wall of the rotating rod 14;

[0043] When the engine 2 inputs power into the gearbox 3 through the transmission wheel 17, the output shaft of the gearbox 3 will drive the first transmission gear 5 to rotate, thereby driving the second transmission gear 41 to rotate through the transmission chain. When the second transmission gear 41 rotates, it will drive the transmission shaft 24 on the inner wall to rotate, thereby driving the walking mechanism set on the outer wall of the transmission shaft 24 to operate, driving the scarifier to move forward as a whole to scarify the ginseng bed;

[0044] When the staff needs to adjust the forward direction of the tiller, first the staff pushes the push-pull rod 8 clockwise backward. At this time, the push-pull rod 8 will drive the support shaft 35 fixed on the outer wall to rotate downward, thereby pushing the tray 39 to move into the soil on the ginseng bed through the support rod 36 on the outer wall of the support shaft 35, thereby supporting the entire tiller through the downward rotating support rod 36. Since the tray 39 is movably connected to the support rod 36 through the fixed screw 37 and the connecting frame 38, the staff can now hold the push-pull rod 8 with one hand and rotate the tiller with the other hand to conveniently adjust the direction of the tiller, and then turn the push-pull rod 8 back counterclockwise to allow the walking mechanism set on both sides of the transmission shaft 24 to touch the ground again, and then continue to drive the tiller to move in the adjusted direction to loosen the soil, so that the staff can easily and quickly adjust the moving direction of the tiller.
