The invention also provides a use method of the sapling transportation device convenient to load and unload, which comprises the following steps:

s1, controlling the height, namely rotating the second screw 5 according to the height of the tree seedling, then driving the first screw 4 to rotate, under the screw thread fit, enabling the lug block 8 to move up and down along the movable opening, then synchronously driving the two supporting plates 9 to move, regulating and controlling the space above the supporting plates 9, then lifting the bracket 14, then driving the whole of the first supporting plate 2, the second screw 5 and the supporting plate 9 above to move upwards, enabling the inserted link 7 and the slot 6 to be separated, simultaneously driving the connecting link 24 and the push block 25 to move upwards synchronously by the bracket 14, gradually pushing the clamping link 22 towards the first opening 23 by the push block 25, when the clamping link 22 enters the inside of the guide groove 16 and is positioned below the guide block 17, pressing the clamping link 22, releasing the bracket 14, dropping the guide block 17 onto the clamping link 22, namely fixing the position of the bracket 14, at this moment, rotating the second screw 5 again, adjusting the height of the supporting plate 9 positioned above, adjusting and controlling the distance between the two supporting plates 9 to adapt to the height of the saplings, and finally resetting the bracket 14 to ensure that the inserted link 7 is butted with the slot 6;

s2, adjusting the width, namely rotating the rotary table according to the width of the sapling, then driving the adjusting screw 12, and under the cooperation of the reverse threads, enabling the two partition boards 13 in the same group to move close to or away from each other along the first sliding chute 10 along with the first sliding block 11, so as to adapt to the width of the sapling.

S3, loading saplings, namely placing the saplings between two partition plates 13 in the same group, enabling the saplings to automatically slide downwards to the bottom along a supporting plate 9 and be stacked in order, meanwhile, in the process that the saplings slide downwards, the roots push the speed reducing blocks 32 to enable the speed reducing blocks 32 to retract towards the second openings 28, the second springs 31 are squeezed to reduce the downward sliding speed of the saplings, meanwhile, in the process that the saplings slide downwards, the crowns drive the branch plates 35 to rotate, the branch plates 35 comb branches on the crowns, the beam grooves 36 are matched with the cross-sectional shapes of the crowns, when the saplings are static, the crowns are shaped, the branch plates 35 are matched with the branch rods 37, when the saplings are static, branches of the branches are separated, and the crowns are prevented from being squeezed;

s4, unloading the saplings, namely transporting the saplings to a set place, firstly taking the saplings on the supporting plates 9 at the front positions, then rotating the handles 39 in a reciprocating manner, then driving the first supporting rods 40 to rotate, enabling the second supporting rods 41 to intermittently jack up the rear ends of the supporting plates 9 upwards, enabling the supporting plates 9 to form seesaw movement, enabling the saplings at the rear positions on the supporting plates 9 to move towards the front ends, and taking the saplings at the rear positions out.

The embodiments of the present invention are disclosed as the preferred embodiments, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention and make various extensions and changes without departing from the spirit of the present invention.
