Preferably, the end of each ejector rod 51 is provided with a flat plate for contacting the pot seedlings, which can increase the contact area with the pot seedlings, improve the stability of ejection, and reduce damage to the pot seedling soil. In other embodiments, the first lifting drive member 52 may also be a telescopic oil cylinder, a telescopic air cylinder, or the like.

In this embodiment, as shown in Figures 5 to 11, the seedling tray 2 is a movable seedling tray, including a frame 22, several groups of longitudinal plate groups and several transverse plate groups, and each longitudinal plate group includes a first longitudinal side arranged longitudinally. Plate 23 and the second longitudinal side plate 24, the first longitudinal side plate 23 and the second longitudinal side plate 24 are hingedly installed on the frame 22 around the longitudinal axis respectively, and each transverse plate group includes the first transverse side plate 25 and the first transverse side plate arranged transversely. The second transverse side plate 26, the first transverse side plate 25 and the second transverse side plate 26 are hingedly mounted on the frame 22 around the transverse axis respectively, the longitudinal axis and the transverse axis are perpendicular to each other, the first transverse side plate 25 of each transverse plate group Corresponding to the second transverse side plate 26, each group of longitudinal plate groups is provided with a tooth plate portion 201 between the first longitudinal side plate 23 and the second longitudinal side plate 24 of the longitudinal plate group, and each group of longitudinal plate groups The first longitudinal side plate 23 and the second longitudinal side plate 24 and the first transverse side plate 25 and the second transverse side plate 26 of each set of transverse plate groups between the first longitudinal side plate 23 and the second longitudinal side plate 24 The tooth plate part 201 forms a through-hole bowl cavity 21, and the above-mentioned several groups of longitudinal plate groups and several groups of transverse plate groups are combined to form several bowl holes 21 arranged in a rectangular array. The seedling tray 2 also includes a swing drive assembly for driving the first longitudinal side plate 23 , the second longitudinal side plate 24 , the first transverse side plate 25 and the second transverse side plate 26 to swing.

Since the bowl cavity 21 is surrounded by the tooth plate portion 201 of the first longitudinal side plate 23, the second longitudinal side plate 24, the first transverse side plate 25 and the second transverse side plate 26, the first longitudinal side plate 23, the second longitudinal side plate The side plate 24, the first transverse side plate 25 and the second transverse side plate 26 are installed on the frame 22 in a swingable manner, and the inclination angle of the inner wall of the bowl cavity 21 can be changed by controlling the swing angle of each side plate through the swing drive assembly, so that the bowl cavity 21 is converted between the two forms of hexahedral through hole and square truncated through hole, that is, the bowl cavity 21 can be changed into a square truncated through hole with a cross-sectional area gradually decreasing from one end to the other end or a cross-sectional area from one end to another. The hexahedral through hole that remains unchanged from one end to the other end increases the inclination angle of the inner wall of the bowl hole 21 (each side plate swings to the inside of the corresponding bowl hole 21) when growing seedlings, so that the bowl hole 21 is in the form of a square truss-shaped through hole ( See Fig. 11), the pot seedling soil pot of its pot hole 21 seedling raising stroke is also in the shape of a four-sided platform; when the pot seedlings need to be ejected, the inclination angle of the inner wall of the pot hole 21 is reduced (each side plate faces the corresponding pot hole 21 outside swing), so that the bowl hole 21 is in the form of a hexahedral through hole (see Figure 10), so that the pot seedling soil bowl can be separated from the inner wall of the bowl hole 21, the contact area between the pot seedling soil bowl and the inner wall of the bowl hole 21 can be reduced, and the pot hole can be reduced. The friction between the seedlings and the inner wall of the bowl hole 21 when the seedlings are pushed out of the bowl hole 21 makes it easier for the pot seedlings to be ejected, which can realize convenient and fast removal of the pot seedlings, reduce the requirements for the ejection mechanism 5, and also reduce the ejection When the pot seedling soil pot is damaged, the survival rate of the pot seedlings after transplanting is greatly improved.

In this embodiment, the swing drive assembly includes a first swing drive mechanism for driving all the first longitudinal side plates 23 to swing synchronously, a second swing drive mechanism for driving all the second longitudinal side plates 24 to swing synchronously, and a second swing drive mechanism for driving all the second longitudinal side plates 24 to swing synchronously.

The X-direction sliding driver, the Y-direction sliding driver and the Z-direction sliding driver adopt prior art, for example, a combination of a motor, a gear and a rack, or a combination of a motor and a ball screw mechanism can be used.

The output mechanism can adopt the pot seedling output mechanism 4 shown in Figure 1 and Figure 4, the pot seedling output mechanism 4 is a belt conveyor, the present embodiment specifically uses a belt conveyor, and the belt conveyor also uses a synchronous belt to drive the winding conveyor belt All driving rollers rotate synchronously, which can ensure the accuracy and controllability of conveying. Further, both sides of the belt conveyor are also equipped with anti-deviation guide side plates.

The above-mentioned seedling tray input mechanism 3 and pot seedling output mechanism 4 are arranged side by side on the same side of the pot seedling transfer mechanism 6, and the delivery direction of the seedling tray input mechanism 3 is parallel and opposite to that of the pot seedling output mechanism 4, which can improve the structure. The compactness is beneficial to reduce the turning radius of the implement in the field. Preferably, the seedling tray input mechanism 3 and pot seedling output mechanism 4 arranged side by side are welded together through connecting rods.

When the pot seedling unloading device of the present embodiment is combined with the pot seedling output mechanism 4 and the pot seedling transfer mechanism 6 to take seedlings and send seedlings, its working principle and process are as follows:

Place the seedling tray 2 with potted seedlings on the seedling tray input mechanism 3, and the seedling tray 2 is transported forward along with the seedling tray input mechanism 3. Component 9 intervenes in the work and cuts off the drive motor power supply of the seedling tray input mechanism 3, so that the seedling tray input mechanism 3 stops conveying the seedling tray 2, and then the first lift driver 52 of the ejector mechanism 5 acts to drive all the wedge-shaped push rods 29 and all the ejectors. Rod 51 rises simultaneously, and each wedge-shaped push rod 29 promotes the corresponding swing linkage bar to make the pot hole 21 of the seedling plate 2 become a hexahedron-shaped through hole from a square truss-shaped through hole, so that the pot seedling is separated from the side wall of the pot hole 21, Thereby reducing the contact area between the pot seedling soil bowl and the inner wall of the bowl hole 21, and reducing the friction between the pot seedlings and the inner wall of the bowl hole 21 when the pot seedlings are pushed out of the bowl hole 21. When the seedling tray 2 is opened, each ejector rod 51 will push out the pot seedlings in the corresponding pot hole 21, and then the three-dimensional space displacement driving assembly 62 of the pot seedling transfer mechanism 6 drives the seedling picking claw 61 to move, holding all the pot seedlings at a time And the pot seedlings are transferred to the pot seedling output mechanism 4 according to the set route, and are transported to the transplanter by the pot seedling output mechanism 4, and the follow-up operation can be carried out.

The above descriptions are only preferred implementations of the present invention, and the scope of protection of the present invention is not limited to the above examples. For those skilled in the art, improvements and transformations obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
