[0033] When the walking wheel 2 stops rotating, the drill is pressed downward to dig a hole, since the walking wheel 2 drives the car body 1 to walk forward by the same distance each time, the spacing of the holes dug by the drill on the ground is also the same.

[0034] The vehicle body 1 rotates a material dropping belt 5, and the material dropping belt 5 is fixed with a plurality of material dropping grooves 6, the material dropping grooves 6 are fixed with the material dropping belt 5 through bolts, the vehicle body 1 also rotates a clamping belt 7, the clamping belt 7 is fixed with clamping blocks 8 matched with the material dropping grooves 6, the clamping blocks 8 are fixed on the clamping belt 7 through bolts, the bottom of the vehicle body 1 is provided with a planting hole, the planting hole is located between the material dropping belt 5 and the clamping belt 7; the potato seedlings to be planted are placed in the material dropping grooves 6, with the material dropping belt 5 driving the material dropping grooves 6 to rotate downward, the clamping blocks 8 and the material dropping grooves 6 are clamped with each other, driving the sweet potato seedlings to move downward, and falling into the dug hole from the planting hole.

[0035] The distance of the walking wheel 2 walking forward is equal to the distance between the drilling tool and the planting hole.

[0036] The bottom of the vehicle body 1 is fixed with a soil covering plate 9, after the potato seedlings enter the hole, the soil covering plate 9 walks forward with the vehicle body, and pushes the soil beside the hole to cover the root of the potato seedlings.

[0037] The drilling tool comprises a shell, the shell rotates a drill bit 4, one side of the shell is fixed with a rack 11 matched with a half gear 10, the upper end of the drilling tool is fixed with a drill bit motor capable of driving the drill bit 4 to rotate, and the top of the shell is connected with the vehicle body 1 through a spring 12.

[0038] When the half gear 10 is disengaged from the power wheel 3, the half gear 10 starts to engage with the rack 11, at this time the walking wheel 2 stops walking, the half gear 10 drives the drilling tool to move downward through the rack 11, the drill bit 4 drills a hole with a proper depth on the ground, and the spring 12 is stretched at this time; when the half gear 10 is disengaged from the rack 11, the drilling tool is lifted and reset under the action of the spring 12, at this time the half gear 10 continues to engage with the power wheel 3, so that the walking wheel 2 walks forward by the same distance, and the distance of the dug hole is the same.

The end of the telescopic rod 22 penetrating into the switch 19 is fixed with the conductive plate 21.

[0050] When the drilling tool moves downward, the pressing rod 24 begins to press the telescopic rod 22. After the pressing rod 24 and the telescopic rod 22 are in contact, the compression spring 25 is first compressed. With the continuous pressing of the pressing rod 24, the conductive plate 21 begins to contact the contact 20, so that the feeding motor is powered on and starts to rotate. With the continuous pressing of the pressing rod 24, the compression spring 25 and the telescopic rod 22 are compressed. At this time, the conductive plate 21 and the contact 20 continuously maintain the power-on state, so that the feeding motor is continuously powered on during the pressing process of the drilling tool, and the falling belt 5 has sufficient time to drive the falling chute 6 to send the potato seedlings into the hole.
