DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] like Figure 1The chain pot seedling tray a shown includes a seedling pot a1 and a belt body a2 connecting the seedling pots a1. The seedling pots a1 are cultured with seedlings and are filled with a cultivation medium for cultivating the seedlings. The seedling pots a1 in the chain pot seedling tray a are in a gathered state and are in a tray shape. After being placed on a transplanter, the chain pot seedling tray a gradually unfolds into a chain shape when the transplanter is running. When the chain pot seedling tray a is in a gathered state, the seedling pots a1 are arranged in multiple rows, and the seedling pots a1 in adjacent rows are inlaid with each other, so that the seedling pots a1 can be arranged tightly, and more seedling pots a1 can be arranged in a unit area. Preferably, the seedling pots a1 are hexagonal or square in shape when viewed from above. Figure 2 As shown, when the seedling pot a1 is in a hexagonal shape, the chain pot seedling plate a is in a honeycomb shape.

[0033] like Figure 3 As shown, the chain pot seedling tray management device of the chain pot transplanter of the present invention includes a seedling tray placement position 1, the seedling tray placement position 1 is connected to the slide 3, the chain pot seedling tray a in the seedling tray placement position 1 can be gradually unfolded into the slide 3 to supply seedlings to the transplanting mechanism of the transplanter; the seedling tray placement position 1 can accommodate a plurality of chain pot seedling trays a, some of which can be incomplete chain pot seedling trays a, that is, the incomplete chain pot seedling tray a is also called a chain pot seedling tray a, the seedling tray placement position 1 can at least accommodate one complete chain pot seedling tray a and one incomplete chain pot seedling tray a, when the consumption of the chain pot seedling tray a for the transplanting operation reaches a set level (for example, half a The chain pot seedling tray a is consumed), and the next chain pot seedling tray a is placed at the seedling tray placement position 1; the chain pot seedling tray management device also includes a connecting mechanism 2; the chain pot seedling tray a has connecting belts at both ends, which are the head end connecting belt a3 and the tail end connecting belt a4; the connecting mechanism 2 can connect the tail end connecting belt a4 of the rear chain pot seedling tray a with the head end connecting belt a3 of the front chain pot seedling tray a, so that the connection between adjacent chain pot seedling trays a can be achieved, so that the seedling pots a1 can be continuously unfolded to achieve continuous seedling supply. After one chain pot seedling tray a is used up, there is no need to stop the machine to deploy another chain pot seedling tray a, which can improve the transplanting efficiency.

[0034] The connecting mechanism 2 is movable, and when the seedling tray connection operation is required, the connecting mechanism 2 moves to the connecting position for connection, and after the pressing is completed, the connecting mechanism 2 moves away from the connecting position for making way.

[0035] Preferably, if Figure 4As shown, the connection mechanism 2 includes pressing units that can be relatively opened and closed, namely, a first pressing unit 21 and a second pressing unit 22; during operation, the head end connection belt a3 and the tail end connection belt a4 to be connected are overlapped and placed between the two pressing units, and the first pressing unit 21 and the second pressing unit 22 are relatively closed to connect the head end connection belt a3 and the tail end connection belt a4. The two pressing units realize the connection between the head end connection belt a3 and the tail end connection belt a4 by pressing out a plurality of pressing points arranged in an array on the connection belt; the belt body shape at the pressing point position on the connection belt changes.

[0036] Preferably, the bottom of the seedling tray placement position 1 has an actively operating transport unit 11, and fixed ribs 12 are provided on both sides of the transport unit 11. The transport unit 11 can be in the form of a flat belt, etc. In this way, the operation of the transport unit 11 can move the chain pot seedling tray a inside it backward, thus making room for loading new seedling trays.

[0037] The structure of the lamination unit and the connection method between the belt bodies will be described below in detail with reference to embodiments.

[0038] Embodiment 1

[0039] In this embodiment, at the pressing point, the belt body is deformed to form a protrusion that deviates from the belt body. Figure 4 As shown, each of the pressing units is provided with a protruding pressure point 2a and / or a concave groove 2b; the protruding pressure point 2a on one pressing unit is provided in pairs with the concave groove 2b on another pressing unit. When the pressing operation is performed, the protruding pressure point 2a applies force to the belt body and embeds a part of the belt body into the concave groove 2b, so that a protruding portion is formed on the connecting belt. By providing multiple rows of protruding pressure points 2a, multiple rows of protruding portions can be dispersedly pressed out on the connecting belt. At each protruding portion, due to the deformation of the belt body and the protruding portions on the two stacked connecting belts protruding in the same direction, the protruding portion of one connecting belt is embedded in the other connecting belt, so that the two connecting belts are connected, so that a certain tensile strength is formed between the two connecting belts.

[0040] like Figure 4As shown, the first pressing unit 21 is entirely provided with protruding pressure points 2a, and the second pressing unit 22 is entirely provided with recessed grooves 2b. The first pressing unit 21 and the second pressing unit 22 are relatively translated and opened and closed under the action of the bidirectional lead screw 25. The two ends of the bidirectional lead screw 25 have two threaded portions with opposite rotation directions. The two threaded portions and the two pressing units respectively form thread pairs, so that when the bidirectional lead screw 25 rotates, the two pressing units can be driven to open and close. In other embodiments, the first pressing unit 21 and the second pressing unit 22 can be installed on an electric clamp or a pneumatic clamp (such as a clamp cylinder), and the relative movement of the two pressing units can be translational opening and closing, or rotational opening and closing.

[0041] Preferably, if Figure 5 As shown, each pressing unit has both a protruding pressure point 2a and a recessed groove 2b, which together form a square array. In each row of the square array, the protruding pressure points 2a and the recessed grooves 2b are arranged alternately, and at the same end of two adjacent rows, the end of one row is a protruding pressure point 2a, and the end of the other row is a recessed groove 2b. In this way, the protruding pressure points 2a and the recessed grooves 2b form a composite array, and each connecting belt has a portion embedded in another connecting belt connected to it, which can effectively increase the stability of the connection between the connecting belts. In this way, the pressed protruding portion a5 is also as shown in FIG. Figure 6 and Figure 7 Hybrid array shown.

[0042] In this embodiment, the protruding pressure point 2a is Figure 7 The rounded rectangular shape shown in , can also be a circle, an ellipse and other shapes.

[0043] Preferably, if Figure 8 As shown, the connecting mechanism 2 also includes a pre-pressing unit 23, and the pre-pressing unit 23 is arranged on both of the pressing units, and an elastic element 24 is arranged between the pre-pressing unit 23 and the connecting mechanism 2. In the process of the two pressing units closing with each other, before the pressing unit acts on the connecting belt, the two pre-pressing units 23 are first closed with each other to press the two connecting belts to be connected, and then the pressing units bite with each other to form a protrusion to realize the connection between the two connecting belts.

[0044] Embodiment 2

[0045] like Figure 9-10 As shown, in this embodiment, the shape of the protruding pressure point 2a is a wedge, which can press out a protruding portion on the connecting belt, which is connected to the belt body on one side and disconnected from the belt body on the other side, that is, a sheet a51 having a certain angle with the belt body is pressed out from the belt body (such as Fig.11As shown), the protruding portion is the sheet a51, and because part of the edge of the sheet a51 is disconnected from the belt body, a hole a6 is formed on the connecting belt. The shape of the sheet a51 is preferably square. In the two connected connecting belts, at each protruding portion, there must be a sheet a51 on one connecting belt that passes through the hole a6 on the other connecting belt. For the sheet a51 that passes through the hole a6 on the other connecting belt, the sheet a51 is closest to the open end of the connecting belt where it is located. In this way, after the protruding portion is formed, when the two connecting belts are subjected to tension, slippage occurs between the two connecting belts, and the sheet a51 that passes through the connecting belt can clamp the edge of the hole a6 passed through the connecting belt to form a clamping structure ( Fig.12 As shown, since a plurality of protrusions arranged in a square array are formed between the two connecting belts, such a snap-fit ​​structure is formed at each protrusion, which can greatly increase the tensile strength of the connection between the two connecting belts.

[0046] Since each pressing unit has both the protruding pressing point 2a and the recessed groove 2b, each of the two connected connecting belts has a sheet a51 that is engaged with the other connecting belt, so that the connection is more stable.

[0047] In this embodiment, similar to the first embodiment, the connection mechanism 2 may also include a pre-pressing unit 23, both of the pressing units are provided with the pre-pressing unit 23, and an elastic element 24 is provided between the pre-pressing unit 23 and the connection mechanism 2. Figure 8 The pressing unit in is replaced by Fig. 9 The pressing unit in.

[0048] Embodiment 3

[0049] In this embodiment, Figure 13-14 As shown, the first docking portion a6 and the second docking portion a7 can be preset on the head end connecting band a3 and the tail end connecting band a4 respectively, the first docking portion a6 has a recess or a through hole, the second docking portion a7 has a protruding unit, and the first pressing unit 21 and the first pressing unit 22 are closed to each other so that the protruding unit of the second docking portion a7 can be embedded in the recess or through hole of the first docking portion a6.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
