The rotation of the upper bevel gear 12 drives the two bevel gears 12 installed on the reciprocating screw assembly 8 to rotate together, thereby driving the two reciprocating screw assemblies 8 to rotate. The rotation of the reciprocating screw assembly 8 drives the moving seat 13 thereon to move, thereby driving tube 2 5 to move. The tubes 2 5 on both sides of the tube 1 4 simultaneously approach or move away from the tube 1 4, thereby completing the required distance adjustment;

[0060] Sowing and discharging; During the movement of the machine body 1, the shaft 10 can drive the magnetic block 18 to rotate through the one-way bearing 2 17. The rotation of the magnetic block 18 causes the magnetic force on the magnetic block 21 to change continuously, thereby driving the blocking block 19 to move, so that the seeds are discharged. At this time, the intermittent opening and closing of the blocking block 19 can be controlled by controlling the opening and closing of the servo motor 19, so as to meet the needs of discharging, and the seed drop sensor 22 will perform corresponding detection during the sowing process. When it is detected that the tube 1 4 or a tube 2 5 has not been discharged, reseeding is performed;

[0061] Replanting; turn on the servo motor 24. The servo motor 24 can drive the reciprocating screw 1 26 to rotate through the one-way bearing 3, and then drive the movable seat 2 34 to move to the required position, corresponding to the uncut tube 1 4 or tube 2 5. Then the servo motor 24 drives the driving end to rotate in the opposite direction. At this time, the reciprocating screw 1 26 stops rotating, and the rod body 25 rotates. The rotation of the rod body 25 can drive the reciprocating screw 2 29 to rotate through the bar rod 30. The rotation of the reciprocating screw 2 29 causes the rack 28 to move. The movement of the rack 28 drives the gear 31 engaged with it to rotate. The rotation of the gear 31 drives the coaxially arranged rotating rod 42 to rotate. The rotation of the rotating rod 42 drives the magnetic block 1 38 to work together. When the magnetic block 1 38 corresponds to the magnetic block 2 39, the baffle 36 moves, and the reseeding seeds in the reseeding hole 35 fall, thereby completing the required reseeding.
