[0040] The working principle of the above technical solution is described as follows:

[0041] When the utility model is in use, the towing hook is connected to a motor vehicle. When the motor vehicle moves forward, the front wheels 20 and the rear wheels 2 rotate, the axle 6 drives the transmission wheel 7 to rotate, and the transmission wheel drives the turntable to rotate. The rotation of the turntable drives the connecting arm to swing, causing the connecting rod to swing and further driving the duckbill 4 to move up and down; the control rope controls the opening of the first opening and closing piece and the second opening and closing piece, and the return spring 44 is used to close the first opening and closing piece and the second opening and closing piece. When the duckbill moves downward, the return spring drives the conical cylinder to close. When the duckbill moves upward, the control rope is used to drive the first opening and closing piece and the second opening and closing piece to rotate around the hinge point, opening the conical cylinder.

[0042] The rotating shaft drives the seedling placing tray to rotate. The operator places the saplings into the disc on the seedling placing tray, and the cuttings fall into the seedling placing cylinder and then into the duckbill from the seedling placing cylinder.

[0043] As Figure 7 、 Figure 8 As shown, the up and down movement of the duckbill is controlled by the turntable. When the turntable rotates one circle, the duckbill moves up and down once. The movement trajectory of the duckbill is reciprocating from A to B and from B to A. When moving from B to C, the duckbill needs to open, and the opening of the duckbill is determined by the control rope. That is, during the rotation of the turntable, when the cylinder 11 moves from point F to point E, the cylinder 11 interferes with the control rope. The control rope is an elastic rope and can stretch within a certain range. When the duckbill moves to point B, it has basically reached the elongation limit of the control rope. At this time, by slightly interfering with the control rope, the duckbill opens. After the cylinder 11 interferes with the control rope and then disengages from the control rope, the duckbill closes after moving upward through point C, thus realizing the opening of the duckbill at a determined moment.

[0044] When the duckbill moves downward, the duckbill closes and at the same time digs a small pit in the ground. When the duckbill is at the lowest point, the control rope drives the duckbill to open, and then the cuttings fall. The duckbill rises, and the subsequent negative pressure wheel 152 backfills and compacts the cuttings through the inclined edge.

[0045] Compared with the related technology, the seedling rapid cutting equipment for seedling breeding provided by the utility model has the following beneficial effects: it realizes the automatic lifting of the duckbill and the automatic opening and closing of the conical cylinder, which not only reduces manual operation but also greatly improves the automation level of the cutting operation, thus significantly improving the operation efficiency; it realizes the precise control of the conversion and lifting process of the duckbill, ensuring that when the duckbill moves to the cutting operation position, it can automatically descend to the appropriate position and automatically trigger the backfilling operation, making the cutting operation more accurate and reliable.

[0046] The duckbill is 5 cm wide and 18 cm long; the distance between two duckbills is 55 - 60 cm, which is also the ridge spacing; the distance between two groups of negative pressure wheels is designed according to the distance between two duckbills.

[0047] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
