Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] Please refer to Figure 1 , a seedling tray for a transplanter in this embodiment includes two side seedling trays 1, the side seedling trays 1 are respectively used for the left and right sides of the seedling tray, and the two side seedling trays 1 are connected by a positioning structure 3.

[0041] It further includes a plurality of assembled seedling trays 2, the plurality of assembled seedling trays 2 are continuously distributed between the two side seedling trays 1, and the side seedling trays 1 and the assembled seedling trays 2 are jointly connected to form a seedling tray structure applied to a transplanter.

[0042] It should be supplemented that drainage grooves 5 are respectively and penetratingly formed on the surfaces of the side seedling trays 1 and the assembled seedling trays 2 to provide a flow path so that the mud carried by the seedlings can not accumulate on the surfaces of the side seedling trays 1 and the assembled seedling trays 2.

[0043] At the same time, brackets 6 are fixedly installed on the surfaces of the side seedling trays 1 and the assembled seedling trays 2, and the brackets 6 are arranged along the surface arcs of the side seedling trays 1 and the assembled seedling trays 2 to block the sundries carried by the roots of the seedlings and reduce the cleaning difficulty of the seedling tray in the later stage.

[0044] In this embodiment, the positioning structure 3 includes a positioning rod 301 fixedly connected to the side seedling tray 1. The positioning rod 301 penetrates through the outer plates of two side seedling trays 1 at the same time, so that the two side seedling trays 1 are connected to each other;

[0045] Furthermore, a locking nut 302 is provided at one end of the positioning rod 301 extending to the outside of the side seedling tray 1 for fastening.

[0046] It can be understood that the positioning rod 301 is composed of multiple small segments connected by threads to each other, so that its length can be selected according to different numbers of assembled seedling trays 2.

[0047] Please refer to Figures 2 to 3 , in this embodiment, a coupling mechanism is provided on the rear sides of the side seedling tray 1 and the assembled seedling tray 2 to complete detachable assembly connection. The coupling mechanism includes a slide rail 7 and a slider 702;

[0048] Among them, the slide rail 7 abuts against the rear sides of the side seedling tray 1 and the assembled seedling tray 2, and both the side seedling tray 1 and the assembled seedling tray 2 are fixedly connected to the slider 702 to achieve assembly positioning.

[0049] Further, a stepped chute 701 is formed on the rear side of the slide rail 7, and the slider 702 is slidably connected to the chute 701. It should be noted that the chute 701 penetrates through the slide rail 7, and a convex block penetrating through the chute 701 protrudes from one side of the slider 702 facing the side seedling tray 1 or the assembled seedling tray 2;

[0050] A threaded hole penetrates through the convex block and is threadedly fitted with a bolt 703 threadedly connected to the side seedling tray 1 or the assembled seedling tray 2.

[0051] During use, the slide rail 7 with the slider 702 is abutted against the rear side of the assembled seedling tray, and the bolt 703 is passed through the slider 702 to fixedly connect the slider 702 to the corresponding seedling tray, so that a plurality of assembled seedling trays 2 can be positioned after being assembled with the side seedling tray 1.

[0052] Please refer to Figures 3 to 4 , in this embodiment, a locking mechanism for locking the slider 702 relative to the slide rail 7 is further provided on the slider 702. The locking mechanism is symmetrically distributed on both sides of the slider 702 to provide bilateral stable extrusion locking;

[0053] Among them, through holes 10 penetrate through both sides of the slider 702 up and down. The locking mechanism includes a locking pin 11 slidably disposed in the through hole 10 and an extrusion member for extruding the locking pin 11. Two locking pins 11 slide simultaneously inside the through hole 10, and a gap is reserved between the two locking pins 11 to facilitate the subsequent extension of the locking pin 11 to the outside of the through hole 10.

[0054] Further, the extrusion member includes a threaded tube 8 communicating with the through hole 10 and a rotating rod 9 threadedly connected to the threaded tube 8. One end of the rotating rod 9 extends into the through hole 10 and contacts both of the locking pins 11 simultaneously.

[0055] Furthermore, an extrusion block 901 is integrally connected to one end of the rotating rod 9 extending into the through hole 10, and an arc-shaped block 1102 is correspondingly connected to one end of the locking pin 11 facing the extrusion block 901.

[0056] Both the above-mentioned extrusion block 901 and arc-shaped block 1102 adopt a hemispherical structure. With this design, the rotating rod 9 can maintain good contact with the end of the locking pin 11 during rotation, and at the same time, by rotating the rotating rod 9, the two locking pins 11 can be evenly extruded simultaneously.

[0057] It should be noted that friction blocks 1101 are integrally connected to the parts of the locking pins 11 corresponding to both ends of the through hole 10. The surface of the friction blocks 1101 is a grinding surface with roughness meeting the requirements, which is used to improve the locking effect when the locking pins 11 contact the sliding groove 701 after protruding.

[0058] Supplementary note is that circular arc-shaped spring pieces 1001 are fixedly installed at both ends of the through hole 10. The spring pieces 1001 are arranged in a circular shape at the end of the through hole 10. Through the natural blockage of the spring pieces 1001, the position of the locking pins 11 can be restricted, and under the natural extrusion of the spring pieces 1001, the locking pins 11 can be retracted and reset.

[0059] Please refer to Figure 4 , in order to further assist in positioning the assembly seedling tray 2 relative to the side seedling tray 1, a mounting seat 4 is fixedly installed at the upper end of the assembly seedling tray 2. A hook 401 that is fastened to the positioning rod 301 is movably installed on the mounting seat 4. By reversing and fastening the hook 401 on the positioning rod 301, the installation of the assembly seedling tray 2 can be assisted.

[0060] Since a rotational force needs to be provided for the hook 401 to swing, a shaft tube 402 is fixedly connected to the lower end of the hook 401. Connecting shafts 403 are fixedly installed on both side surfaces of the mounting seat 4 facing the shaft tube 402. The hook 401 can swing relative to the mounting seat 4 by rotating the shaft tube 402 relative to the connecting shafts 403.

[0061] Further, a torsion spring seat 405 is fixedly installed on the inner wall of the connecting shaft 403. A torsion spring 404 that provides a torsional acting force is connected between the torsion spring seat 405 and the shaft tube 402. One end of the torsion spring 404 is fixedly connected to the torsion spring seat 405, and the other end is fixedly connected to the shaft tube 402. When the shaft tube 402 rotates relative to the connecting shaft 403, the torsion spring 404 can be pulled to twist and generate a reset acting force.

[0062] It should be noted that the hook 401 is in close contact with the vertical surface of the assembled seedling tray 2 at the initial position. Therefore, when the assembled seedling tray 2 passes over the positioning rod 301, the hook 401 can be blocked by the positioning rod 301 and rotate, and the torsion spring 404 provides a torsional force to make the hook 401 latch onto the positioning rod 301.

[0063] The working principle of the above embodiment is as follows: when it is necessary to assemble and use to change the configured width of the seedling tray, by reducing the number of assembled seedling trays 2, select an appropriate number of assembled seedling trays 2 and the corresponding number of small sections of the positioning rod 301 for the assembled seedling tray 2;

[0064] First, connect multiple sections of the positioning rod 301 to support and connect the two side seedling trays 1 to form a seedling tray frame. Abutt the slide rail 7 with the slider 702 against the rear side surfaces of the two side seedling trays 1, and then use bolts 703 to fixedly connect the side seedling trays 1 and the two sliders 702 at both ends inside the slide rail 7, so as to form a support between the two side seedling trays 1;

[0065] Then, place the corresponding assembled seedling tray 2 at the position between the two side seedling trays 1, swing the hook 401 at the end of the assembled seedling tray 2, so that the hook 401 can pass over the positioning rod 301. The hook 401 rotates relative to the mounting seat 4 at the end of the assembled seedling tray 2, causing the torsion spring 404 installed in the shaft tube 402 to twist and generate a torsional force. Under the action of the torsional force, the hook 401 rebounds and latches onto the positioning rod 301. At this time, the heights of the assembled seedling tray 2 and the side seedling tray 1 are in alignment. After all the assembled seedling trays 2 are installed, fasten them to the rear slider 702 with bolts 703;

[0066] Finally, rotate the rotating rod 9 on the side of the slider 702 relative to the threaded tube 8. The rotating rod 9 extends into the through hole 10 inside the slider 702 when rotating relative to the threaded tube 8. By pressing the locking pin 11 in the through hole 10 with the rotating rod 9, the locking pin 11 extends outside the through hole 10 and contacts the chute 701 on the slide rail 7, so as to complete the locking of the position of the slider 702, and also make the assembled structure of the assembled seedling tray 2 and the side seedling tray 1 stable.
