Abstract
Description
Technical Field
[0001] This utility model relates to transplanting equipment, and more particularly to a seedling cup assembly for a transplanting machine. Background Technology
[0002] A transplanter is a seedling transplanting device. It works by sequentially placing seedlings from seedling trays into individual seedling cups on a moving platform. The moving cups then open their bottom openings sequentially via a mechanism, allowing the seedlings to be placed into the machine's spout, which then plants them into the field. Currently, most seedling cups have a single-door structure. This structure makes it easy for seedlings to tilt and become inverted when placed into the spout, hindering placement and affecting transplanting. While some seedling cups now have a double-door structure, the opening degree of these double-door structures is constantly changing from open to closed, resulting in a short period of stable opening, which is also detrimental to seedling placement and transplanting. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a seedling cup assembly for a transplanter that facilitates seedling placement and ensures normal transplanting of seedlings.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a seedling cup assembly for a transplanter, including a seedling cup body with openings at the top and bottom. An active baffle and a passive baffle extending downwards are respectively provided on opposite sides of the bottom of the seedling cup body. The tops of the active baffle and the passive baffle are rotatably connected to the seedling cup body via rotating shafts. A push arm extends from the side of the active baffle toward the passive baffle. An opening and closing groove corresponding to the end of the push arm is provided on the side of the passive baffle facing the active baffle. The end of the push arm extends into the opening and closing groove and contacts the inner wall of the groove. The active baffle and the passive baffle are each provided with an elastic device that drives the lower parts of the active baffle and the passive baffle to move closer together.
[0005] The opening and closing groove is an arc-shaped groove, which includes an outer arc segment. The lower end of the outer arc segment is provided with an opening segment and an inner arc segment in sequence towards the active baffle. The two ends of the opening segment smoothly transition with the outer arc segment and the inner arc segment, respectively.
[0006] As a preferred technical solution, the length of the opening segment is less than or equal to the center distance between the outer arc segment and the inner arc segment.
[0007] As a preferred technical solution, the two sides of the active baffle and the passive baffle are respectively provided with side plates extending outwards from each other, the two side plates of the active baffle are respectively provided with push arms, and the two side plates of the passive baffle are respectively provided with corresponding opening and closing grooves.
[0008] As a preferred technical solution, two supports are respectively provided on opposite sides of the seedling cup body, and two mounting ears are respectively provided on the top sides of the active baffle and the passive baffle. The mounting ears on the active baffle and the passive baffle are respectively rotatably connected to the corresponding supports through a rotating shaft, and the elastic device is a torsion spring fitted on a pin shaft.
[0009] As a preferred technical solution, a bearing is rotatably mounted at the end of the push arm, and the bearing makes rolling contact with the inner wall of the opening and closing groove.
[0010] As a preferred technical solution, the end of the push arm is provided with a protrusion, which slides in contact with the inner wall of the opening and closing groove.
[0011] As a preferred technical solution, a roller is rotatably mounted on the active baffle located below the push arm via a pin shaft, and a chain plate mounting seat is installed on the side of the seedling cup body.
[0012] The transplanter's seedling cup assembly, employing the aforementioned technical solution, features downward-extending active and passive baffles on opposite sides of the cup's bottom. When the bottoms of the active and passive baffles are nearly closed, a space wider at the top and narrower at the bottom is created between them, facilitating the upright placement of the seedling within the cup. The cooperation of the push arm and the opening / closing groove ensures that the passive baffle swings outwards in sync with the active baffle, opening the bottom of the seedling cup and allowing the seedling to be placed upright into the transplanter's spout. Furthermore, the push arm and opening / closing groove work together to drive the active and passive baffles to swing open and close, minimizing the time the baffles remain in a stable, high-opening state, further aiding in seedling placement and ensuring successful transplanting.

Detailed Implementation
[0021] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, in the drawings, the same reference numerals are assigned to components that are substantially the same in structure and function, and redundant descriptions of substantially the same components have been omitted to make the description more concise.
[0022] like Figure 1 and 2 As shown, the transplanter's seedling cup assembly includes a seedling cup body 1 with openings at the top and bottom. An active baffle 2 and a passive baffle 3 extending downwards are respectively provided on opposite sides of the bottom of the seedling cup body 1. The tops of the active baffle 2 and the passive baffle 3 are rotatably connected to the seedling cup body 1 via a rotating shaft 14. A push arm 4 extends from the side of the active baffle 2 towards the passive baffle 3. An opening and closing groove 5 corresponding to the end of the push arm 4 is provided on the side of the passive baffle 3 facing the active baffle 2. The end of the push arm 4 extends into the opening and closing groove 5 and contacts the inner wall of the groove 5. The active baffle 2 and the passive baffle 3 are respectively provided with elastic devices 6 that drive the lower parts of the active baffle 2 and the passive baffle 3 to move closer together. The end of the push arm 4 and the opening and closing groove 5 form a sliding structure. The end of the push arm 4 and the opening and closing groove 5 are engaged. Under the action of the elastic device 6, the initial state of the active baffle 2 and the passive baffle 3 is closed. A space with a smaller bottom and a larger top is formed between the active baffle 2 and the passive baffle 3, and the seedling is placed upright in the seedling cup. When working, the external force drives the active baffle 2 to swing outward, which drives the push arm 4 to swing down. The end of the push arm 4 presses down on the inner wall of the opening and closing groove 5, which drives the passive baffle 3 to swing outward in sync, opening the bottom opening of the seedling cup. The seedling is placed into the duckbill in an upright state.
[0023] like Figure 3 As shown, the opening and closing groove is an arc-shaped groove, and the opening of the arc-shaped groove faces the active baffle 2, which facilitates the insertion and engagement of the end of the push arm 4. The opening and closing groove includes an outer arc segment 53. The lower end of the outer arc segment 53 is provided with an opening section 52 and an inner arc segment 51 sequentially facing the active baffle 2. The two ends of the opening section 52 smoothly transition with the outer arc segment 53 and the inner arc segment 51, respectively. The opening section 52 is a plane, but it can also be an arc surface with a small curvature, and its curvature should be much smaller than that of the outer arc segment 53 and the inner arc segment 51. Figure 5As shown in Figure a, in the initial state of the active baffle 2 and the passive baffle 3, the active baffle 2 and the passive baffle 3 are closed, and the end of the push arm 4 is located at the inner arc segment 51 within the opening and closing groove 5. During operation, external force drives the active baffle 2 to swing outward, causing the push arm 4 to swing downward. The end of the push arm 4 moves along the opening segment 52 within the opening and closing groove 5 towards the outside of the passive baffle 3, pushing the passive baffle 3 to swing outward until it slides to the outer arc segment 53 of the opening and closing groove 5. Figure 5 As shown in Figure b, at this time, the active baffle 2 and the passive baffle 3 are in a semi-open state. External force drives the active baffle 2 to continue swinging outward, causing the push arm 4 to continue swinging downward. The end of the push arm 4 moves in the opposite direction along the opening section 52 within the opening and closing groove 5, pushing the passive baffle 3 to continue swinging outward until the end of the push arm 4 returns to the inner arc section 51 of the opening and closing groove 5. Figure 5 As shown in Figure c, the active baffle 2 and the passive baffle 3 are in the open state at this time. Because the opening section 52 is gentler than the inner arc section 51 and the outer arc section 53, the time for the active baffle 2 and the passive baffle 3 to maintain a stable large opening is extended when they are open, which is beneficial for the placement of seedlings. In particular, the opening of the active baffle 2 and the passive baffle 3 can be achieved by the reciprocating movement of the end of the push arm 4 in the opening and closing groove 5, which reduces the space of the opening and closing groove 5 and the movement space of the push arm 4, making it easier to arrange the opening part structure on the active baffle 2 and the passive baffle 3.
[0024] like Figure 6 As shown, the length of the opening section 52 is less than or equal to the center distance between the outer arc section 53 and the inner arc section 51, which facilitates the reciprocating motion of the end of the push arm 4 within the opening and closing groove without interference. When the active baffle 2 and the passive baffle 3 are in a half-open state, the end of the push arm 4 reaches the maximum point of the opening and closing trajectory, and the outward movement of the end of the push arm 4 reaches its maximum. If the center distance between the outer arc section 53 and the inner arc section 51 is too small at this time, the opening and closing groove will interfere with the end of the push arm 4, making it impossible for the active baffle 2 and the passive baffle 3 to open.
[0025] like Figure 1 and 2 As shown, the active baffle 2 and the passive baffle 3 have side plates 7 extending out from their respective sides. The active baffle 2, the passive baffle 3, and each side plate 7 cooperate with each other to form a space that is smaller at the bottom and larger at the top around the bottom opening of the seedling cup body 1 when the active baffle 2 and the passive baffle 3 are closed, which facilitates the upright standing of the seedlings. Push arms 4 are provided on the two side plates 7 of the active baffle 2, and opening and closing grooves 5 are provided on the two side plates 7 of the passive baffle 3, which improves the stability of the opening and closing of the active baffle 2 and the passive baffle 3.
[0026] like Figure 4As shown, two supports 8 are respectively arranged at intervals on opposite sides of the seedling cup body 1. Two mounting ears 9 are respectively provided on the top sides of the active baffle 2 and the passive baffle 3. The mounting ears 9 on the active baffle 2 and the passive baffle 3 are respectively rotatably connected to the corresponding supports 8 through the rotating shaft 14. The arrangement of the two mounting ears 9 and the two supports 8 improves the stability of the rotational installation of the active baffle 2 and the passive baffle 3. The elastic device 6 is a torsion spring fitted on the pin shaft 11. The torsion spring can be fitted on the rotating shaft 14 between the two supports 8 to ensure the stability of the torsion spring installation and operation.
[0027] A bearing is rotatably mounted at the end of the push arm 4. The bearing rolls in contact with the inner wall of the opening and closing groove 5. This rolling fit between the bearing and the inner wall of the opening and closing groove 5 improves sensitivity and reduces lubrication inconvenience. The end of the push arm 4 can also be provided with a protrusion 10, which slides against the inner wall of the opening and closing groove 5. This simplifies the structure and reduces assembly operations. For example, the protrusion 10 and the bearing can have a diameter of 12mm. Similarly, the radii of the outer arc segment 53 and the inner arc segment 51 can also be 12mm to facilitate close cooperation with the protrusion 10 and the bearing. The length of the opening segment 52 can be 4mm, and the center distance between the outer arc segment 53 and the inner arc segment 51 can also be 4mm, ensuring that the opening and closing groove does not interfere with the protrusion 10 and the bearing, allowing the active baffle 2 and the passive baffle 3 to open smoothly.
[0028] like Figure 1 and 2 As shown, a roller 12 is rotatably mounted on the active baffle 2 on the lower side of the push arm 4 via a pin 11. The roller 12 cooperates with the opening and closing mechanism on the transplanter to push the active baffle 2 to swing open the active baffle 2 and the passive baffle 3. A chain plate mounting seat 13 is installed on the side of the seedling cup body 1. The chain plate mounting seat 13 is connected to the seedling cup running chain on the transplanter and moves under the drive of the seedling cup running chain.
[0029] like Figure 5 As shown, during operation, the chain plate mounting seat 13 is connected to the seedling cup running chain on the transplanter. Each seedling cup moves under the drive of the seedling cup running chain. The active baffle 2 and the passive baffle 3 are initially in a closed state under the action of the elastic device 6, as shown. Figure 5 As shown in Figure a, the bearing at the end of the push arm 4 is located at the inner arc segment 51 within the opening and closing groove 5. Seedlings on the seedling tray are sequentially placed into the operating seedling cups via the seedling-taking mechanism on the transplanter. When the seedling cup moves above the duckbill, the opening and closing mechanism on the transplanter, in conjunction with the roller 12, pushes the roller 12 to drive the active baffle 2 to swing outwards. Simultaneously, the push arm 4 swings downwards, and the bearing at the end of the push arm 4 presses down against the inner wall of the opening and closing groove 5, moving along the opening segment 52. The passive baffle 3 then swings outwards accordingly. When the bearing reaches the outer arc segment 53, the bearing reaches the maximum point of the opening and closing trajectory, as shown in Figure a. Figure 5As shown in Figure b, the active baffle 2 and the passive baffle 3 are in a semi-open state. The opening and closing mechanism on the transplanter drives the active baffle 2 to continue swinging outward, causing the push arm 4 to continue swinging downward. The bearing moves in the opposite direction along the opening section 52 within the opening and closing groove 5, pressing down and driving the passive baffle 3 to continue swinging outward until the bearing reaches the inner arc section 51, as shown in Figure b. Figure 5 As shown in Figure c, the active baffle 2 and the passive baffle 3 are fully opened, and the seedling falls into the duckbill in an upright position; then the opening and closing mechanism on the transplanter disengages from the roller 12, and the active baffle 2 and the passive baffle 3 swing back and close under the action of the elastic device 6, and the bearing at the end of the push arm 4 moves back to the arc segment 51 inside the opening and closing groove 5.
