The top and bottom ends of the seedling tray 3 are respectively located along the plane of the top and bottom ends of the seedling frame 1 of the planting machine, so that more seedlings can be placed and the seedlings will not fall from the side when the planting machine moves.

[0034] Specifically, Figure 3 As shown, the position of the seedling anti-falling grid frame 5 corresponding to the lower seedling groove 7 is cut into an inclined surface, which can allow the seedlings to slide to the position of the lower seedling groove 7 to avoid the seedlings being left on the seedling anti-falling grid frame 5.

[0035] Specifically, Figure 3 As shown, the two sides of the top frame 6 are raised to form limiting plates.

[0036] Specifically, Figure 2 and Figure 4 As shown, the seedling turning clamp 11 includes a circular clamp plate 1101, a cylinder 1102, a stud 1103 and a fastening nut 1104. The cylinder 1102 is fixedly installed on one side of the circular clamp plate 1101, and the stud 1103 is fixedly installed on the other side of the circular clamp plate 1101. The circular clamp plate 1101, the cylinder 1102 and the stud 1103 are coaxially arranged, and the stud 1103 extends from the adjustment groove 10 to be threadedly connected to the fastening nut 1104.

[0038] Specifically, the width of the lower pressing plate 1204 is the same as the width of the lower seedling groove 7, which is convenient for pressing the seedlings.

[0039] Working principle:

[0040] When in use, the seedling tray 3 is moved on the screw rod 2 according to the planting row spacing, and then the seedling tray 3 is tightened and fixed on the screw rod 2 with a nut to prevent the seedling tray 3 from moving. The first cylinder 9 pushes the blocking bottom plate 8 to move to the position of the lower seedling groove 7, and then the seedling pressing device 12 is moved to one side of the seedling tray 3, that is, to the position above the root of the seedling, and the fastening nut 1104 is loosened. The stud 1103 is moved to move the seedling steering clamp 11 to the middle position of the seedling tray 3, that is, to the middle position of the seedling, and then the fastening nut 1104 is tightened to fix the seedling steering clamp 11;

[0041] Place the seedlings horizontally on the seedling tray 3, with the roots of the seedlings facing the position of the seedling presser 12, and the seedlings slide down along the seedling tray 3 and slide to the position of the lower seedling groove 7. The inner rod of the seedling presser 12 descends, and when the lower pressing plate 1204 presses the roots of the seedlings, the first cylinder 9 retreats with the blocking bottom plate 8, and the arc groove 1205 is positioned to hold the roots of the seedlings down, and the middle part of the seedlings is limited by the cylinder 1102, and the seedlings change from horizontal to vertical. The lower pressing plate 1204 presses the roots of the seedlings deeper and plants them well, while the seedlings on the seedling tray 3 are blocked by the inner rod of the second cylinder 1201 and cannot come down. When the second cylinder 1201 contracts and resets, the first cylinder 9 resets the blocking bottom plate 8, and then the next planting is carried out.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
