The invention relates to a double-track transplanting mechanism based on a differential gear train of a movable shaft non-circular gear, which has the following working principle:
fixing the non-circular gears 1-9 with an external bracket; the input shaft 5 is driven to rotate by external power to drive the first shell 1-1 and the second shell 1-13 of the gear box 1 to rotate, so that the second non-circular gear 1-5 rotates around the first non-circular gear 1-9 to drive the first shaft 9 to rotate, the third non-circular gear 1-6 fixedly connected with the first shaft 9 rotates to drive the fifth non-circular gear 1-3 to rotate, and therefore the second shaft 10 is driven to rotate, and the second shaft 10 rotates to drive the hole opening arm 2 fixedly connected with the second shaft 10 to rotate; meanwhile, the first shaft 9 rotates to drive the fourth non-circular gear 1-7 to rotate, so that the sixth non-circular gear 1-2 sleeved on the second shaft 10 rotates around the second shaft 10, and the sixth non-circular gear 1-2 drives the first cylindrical gear 2-5 to synchronously rotate, thereby driving the second cylindrical gear 2-4 meshed with the first cylindrical gear 2-5 to rotate; the cylindrical gear II 2-4 rotates to drive the shaft III 11 to rotate, and the shaft III 11 rotates to drive the transplanting arm 4 to rotate; along with the meshing rotation between the non-circular gears, the first shaft 9 can drive the first bearing seat 1-10 and the second bearing seat 1-8 to respectively reciprocate up and down along the first chute 1-1-1 and the second chute 1-13-1, the second shaft 10 can drive the third bearing seat 1-11 and the fourth bearing seat 1-4 to respectively reciprocate up and down along the first chute 1-1-1 and the second chute 1-13-1, so that the opening arm 2 and the transplanting arm 4 carry out up and down reciprocating motion relative to the gear box 1, the opening shovel 2-3 in the opening arm 2 and the seedling needle 4-2 in the transplanting arm 4 can be realized according to preset tracks under the condition of one power input (by designing the section curves of the non-circular gears and the transmission ratios of the two cylindrical gears, different preset tracks of the opening shovel 2-3 and the seedling needle 4-2 can be realized, as shown in fig. 2, the track 6 is the movement track of the seedling needle 4-2, and the track 7 is the movement track of the hole opening shovel 2-3), and simultaneously, the posture angles of the hole opening arm 2 and the transplanting arm 4 can be better adjusted based on the up-and-down reciprocating movement of the hole opening arm 2 and the transplanting arm 4 relative to the gear box 1, so that the shape of the opened hole and the planting effect are more ideal.
In the process that the hole opening shovel 2-3 in the hole opening arm 2 and the seedling needle 4-2 in the transplanting arm 4 move according to a preset track, when the transplanting arm 4 moves to a vegetable blanket-shaped seedling tray, the seedling needle 4-2 grabs seedlings from the vegetable blanket-shaped seedling tray (the seedling needle 4-2 is directly inserted into the blanket-shaped seedlings and carries the seedlings out of the blanket-shaped seedling tray), and at the moment, the hole opening shovel 2-3 is positioned at a position lower than the vegetable blanket-shaped seedling tray; after the transplanting arm 4 finishes the seedling grabbing action and before the seedling pushing position, the hole opening shovel 2-3 starts to perform a hole opening action (a position 8 in fig. 2 is a hole opening starting position), the hole opening shovel 2-3 finishes the hole opening action along with the rotation of the hole opening arm 2 (the invention can ensure that the attitude angle of the hole opening shovel 2-3 is about 90 degrees in the whole hole opening process), at the moment, the transplanting arm 4 reaches the seedling pushing position, the cam 3 operates to a return section, the connecting block 4-6 drives the seedling pushing rod 4-3 to push out under the restoring force action of the spring II (when the cam 3 is at the pushing section position, the spring II is in a compression state by driving the connecting block 4-6 through the shifting fork 4-4), and the seedling pushing rod 4-3 pushes the vegetable seedlings into the opened holes to finish the transplanting action.
