The magnetic ring is connected to the control switch 2 in the contact assembly located above or below the annular cutter 3 of the cross section.

[0041] Specifically, after the magnetic ring is turned on, it will produce an adsorption effect on the sliding plate, so that the sliding plate drives the connecting shaft 1 32 to slide downward; after the connecting shaft 1 32 moves, it contacts the connecting shaft 2 33; the transmission gear 2 28 rotates synchronously with the transmission gear 1 26, and drives the annular cutter 3 to rotate through the outer gear ring 31.

A torsion spring is provided at the connection end between the valve and the valve plate 36.

[0043] In one embodiment, the valve plate 36 is embedded with the mounting box 22 at the bottom of the material pipe 1 .

A metal sheet that can be magnetically adsorbed by the magnetic rods 12 is fixed on the side wall of the valve fan 37; the metal sheets on several valve fans 37 are oriented in the same direction. Specifically, after the magnetic rod 12 is energized, the valve fan 37 moves by adsorbing the metal sheet; after the valve fan 37 moves, it is misaligned with the discharge port 38. The magnetic rod 12 is connected to a control switch; the torsion spring is used to drive the valve fan 37 to move and overlap with the discharge port 38 after the control switch is disconnected.

[0045] Several baffles 39 are hingedly provided around the material tube 1. The longitudinal section of the baffle 39 is arc-shaped, and a torsion spring is provided at the hinged end of the baffle 39 and the material tube 1, which is used to drive the baffle 39 to flip toward the axis of the material tube 1. Specifically, several rivets 4 are fixed at the bottom of the baffle 39, which are used to increase the grip of the baffle 39 when the baffle 39 contacts the ground. When the drill bit 13 contacts the ground, the baffle 39 contacts the ground and is pressed to flip away from the axis of the material tube 1; when the drill bit 13 separates from the ground, the baffle 39 is flipped toward the axis of the material tube 1 by the torsion spring.

[0046] Specifically, after the material falls from the discharge port 38, it will fall into the pit drilled by the drill bit 13. When part of the material contacts the drill bit 13, it will be splashed outside the pit due to the high-speed rotation of the drill bit 13; the baffle 39 is used to block the splashed material. After the drill bit 13 is separated from the pit, the rivet 4 at the bottom of the baffle 39 will drive the soil around the pit to move closer to the pit, thereby burying the pit.
