[0064] Specific work:

[0065] When the power is transmitted, the lower transmission sprocket one 10 is installed on the main transmission hexagonal shaft 16 below the frame, and the walking driving wheel 12 is connected through the lower adjusting sprocket 11, the power is transmitted to the seedling clamping transition sprocket two 2.3 on the seedling clamping platform through the intermediate transition sprocket 14 on the intermediate transition shaft 13 above the platform and the side transmission sprocket 15, the power is transmitted to the seedling clamping transition sprocket three 3.2 through the seedling clamping transition sprocket one 2.2 installed on the upper transition shaft 2.1, and then the main transmission shaft 3.1 drives the main transmission gearbox 3.4 and the driving gear 3.3 to rotate, so as to realize the operation of the seedling clamping device; Because the power input of the seedling clamping device comes from the walking driving wheel, there is no power loss problem, and the operation is more stable.

[0066] The main drive shaft 3.1 rotates, driving the main drive gearbox 3.4, the driving gear 3.3, and the driven gear 4.10 to rotate on one side. The main drive gearbox 3.4 causes the push-pull linkage 3.5 to move back and forth, driving the front and rear sliding seat plates 3.6 to move back and forth along the guide rail. The front and rear sliding seat plates 3.6 are connected to the seedling clip seat plate 4.2 through the left fixed support plate 3.7 and the right fixed support plate 3.8. The seedling clip 4.4 and the slider are fixed on the seedling clip seat plate 4.2. Under the action of the seat plate rotating shaft 4.1, the seedling clip 4.4 can rotate with the seedling clip seat plate 4.2. Limit bolts 4.6 and limit tension springs 4.7 are installed on both sides of the seedling clip seat plate 4.2. Two seedling clips 4.4 are connected to an opening and closing telescopic linkage 5.8. The other side of the opening and closing telescopic linkage 5.8 is connected and fixed to the opening and closing fixed plate 5.6. The opening and closing fixed plate 5.6 can move back and forth slightly by relying on the slider below. When the front and rear sliding seat plate 3.6 moves to the front, the two opening and closing telescopic linkages 5.8 close inward, causing the eight seedling clips 4.4 to retract to the center distance between the two seedling holes. When the front and rear sliding seat plate 3.6 moves to the rearmost position, the two opening and closing telescopic linkages 5.8 cause the seedling clips 4.4 to separate to the center distance between the seedling cups. The transmission chain drives the rear tilting transmission sprocket 4.20 to rotate, which drives the upper rotating plate through the rear tilting linkage shaft 4.12. 4.13 rotates, and below the upper rotating plate 4.13 are connected a rotating push-pull plate 4.16, a pull rod shaft 4.17, a rotating limit plate 4.14, and a seedling clip tilting telescopic pull rod 4.18. The front end of the seedling clip tilting telescopic pull rod 4.18 is connected to the tilting upright rod 4.19 on the seedling clip seat plate 4.2, so that the seedling clip 4.4 tilts upward and backward against the seedling clip seat plate 4.2 to pull the seedling out of the seedling tray; the rotating push-pull plate 4.16 is pushed to rotate by the rotating limit plate 4.14 on the upper rotating plate 4.13. When the upper rotating plate 4.13 rotates from the front to the back, the rotating limit plate 4.14 is subjected to force, and the upper rotating plate 4.13 rotates from the rear. When turned to the front, the rotating limiting plate 4.14 is not under force, which allows the seedling clip telescopic rod 4.18 to quickly extend forward. Due to the action of the limiting tension spring 4.7 and the limiting bolt 4.6 installed on the seedling clip seat plate 4.2, the seedling clip 4.4 can quickly return to its original angle after clamping the seedling and pulling it out of the seedling tray, waiting for the seedling to fall. The seedling clip forward movement limiting compression spring 5.7 is installed on the fixed plate 5.6 after opening and closing, and a limiting device is provided at the rear. In this embodiment, there are 8 seedling clips 4.4, which can make the 8 seedling clips 4.4 completely closed and then move forward a certain distance, so that the seedling clips 4.4 on both sides will not interfere with the seedlings on both sides of the seedling tray when clamping the seedlings.

[0067] On the accompanying running transmission sprocket 5.11 is installed with accompanying running push plate 5.14, while the accompanying running transmission sprocket 5.11 rotates, driving the rotation of the accompanying running push plate 5.14, on the rear sliding main plate 5.3 is installed with accompanying running positioning rod 5.12 and accompanying running sliding bearing 5.13, the outer side is installed with accompanying running tension spring 5.9, the rotation of the accompanying running push plate 5.14 pushes the rear sliding main plate 5.3 a certain distance to the side, since the opening and closing expansion link 5.8 connected with the seedling clamp 4.4 is fixed on the upper side, so the seedling clamp 4.4 also translates a distance after clamping the seedling, and then falls the seedling, the accompanying running tension spring 5.9 can make it quickly return to position, waiting for the next step.
