Description

Technical Field

[0001] The utility model relates to the technical field of transplanting, in particular to a seedling taking device for transplanting. Background Technique

[0002] Manual transplanting of greenhouse plug seedlings has a large labor intensity, low efficiency, and it is difficult to guarantee the planting quality. With the application of a large number of advanced industrial technologies in greenhouse production, automatic transplanting of plug seedlings has become the only way for future development.

[0003] As the end effector of the transplanter, the seedling taking mechanism grabs the pot seedlings from the plug trays, holds them, and then releases them into the target holes. The rationality of the design directly affects the operation quality and efficiency of the transplanter. During the grasping process of the existing seedling pickers, it is easy to cause damage to the substrate and the pot seedlings, resulting in a low survival rate of the pot seedlings. Therefore, this application proposes a seedling taking device for transplanting. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a seedling taking device for transplanting to solve the problem that the existing seedling pickers are prone to cause damage to the substrate and the pot seedlings during the grasping process.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 2 shown, a transplanting seedling picking device provided by an embodiment of the present invention includes:

[0031] Support 10;

[0032] A cylinder 20 fixedly connected to the support 10, and a pressing plate 30 is fixedly connected to the output shaft of the cylinder 20;

[0033] At least three seedling picking needles 50 slidably connected to the support 10, the three seedling picking needles 50 are evenly distributed around the cylinder 20 in the circumferential direction around the axis of the cylinder 20, and the end of the seedling picking needle 50 away from the cylinder 20 is inclined towards the axis of the cylinder 20. When the cylinder 20 extends, the pressing plate 30 presses the seedling picking needle 50 to move along its own axis;

[0034] A compression spring 60 sleeved on the seedling picking needle 50, the compression spring 60 abuts against the support 10 and the end of the seedling picking needle 50 close to the pressing plate 30, and the compression spring 60 is compressed when the pressing plate 30 presses the seedling picking needle 50.

[0035] In this embodiment, as Figure 1 and Figure 3As shown in the figure, when taking seedlings, the cylinder 20 is controlled to extend. When the cylinder 20 extends, the guiding tube 40 presses the seedling-taking needle 50 to slide on the support 10. When the seedling-taking needle 50 slides, the compression spring 60 is compressed. One end of the seedling-taking needle 50 away from the cylinder 20 is inserted into the substrate block. At this time, the compression spring 60 is compressed. Since the elastic force of the compression spring 60 becomes larger and larger during the compression process, the reaction force of the compression spring 60 on the seedling-taking needle 50 becomes larger, and the acceleration of the seedling-taking needle 50 inserted into the substrate block gradually becomes smaller. Therefore, a speed buffer is formed when the seedling-taking needle 50 is lifted upward, avoiding damage to the substrate block caused by a huge speed impact. At this time, the manipulator structure connected to the seedling-taking device transports the substrate block to the destination. When the substrate block moves to the destination, the cylinder 20 retracts, and the compression spring 60 pushes the seedling-taking needle 50 to approach the cylinder 20. The seedling-taking needle 50 is pulled out of the substrate block. Since the seedling-taking needle 50 is needle-shaped, it is not easy to damage the pot seedlings after being inserted into the substrate block.

[0036] The transplanting seedling-taking device disclosed in the embodiment of the present invention inserts the substrate block through at least three groups of seedling-taking needles 50. Since the seedling-taking needles 50 are inclined inward, the seedling-taking needles 50 form a claw shape to insert into the substrate block, so that the seedling-taking needles 50 can fix the substrate block and complete the seedling-taking action. When putting down the substrate block, just pull out the seedling-taking needles 50. Compared with the traditional structure, the present invention is not easy to damage the substrate block and the pot seedlings during the seedling-taking process.

[0037] Specifically, in this embodiment, as Figure 1 and Figure 3 shown, the support 10 includes:

[0038] A cylinder fixing plate 11, to which the cylinder 20 is fixedly connected;

[0039] A main fixing plate 12, to which the seedling-taking needle 50 is slidably connected, and the cylinder fixing plate 11 and the main fixing plate 12 are connected by a plurality of connecting rods 13;

[0040] In this embodiment, the cylinder fixing plate 11 and the main fixing plate 12 are arranged in parallel. There are four connecting rods 13. The two ends of the connecting rod 13 are respectively fixedly connected to the cylinder fixing plate 11 and the main fixing plate 12, and the cylinder 20 is fixedly connected to the cylinder fixing plate 11 by bolts;

[0041] Preferably, the connecting rod 13 is a threaded rod. The connecting rod 13 is fixedly connected to the cylinder fixing plate 11 and the main fixing plate 12 through nuts. Nuts are arranged on both sides of the cylinder fixing plate 11 and the main fixing plate 12. The nuts fix the cylinder fixing plate 11 and the main fixing plate 12 by clamping, so that the distance between the cylinder fixing plate 11 and the main fixing plate 12 can be adjusted.

[0042] Preferably, as Figure 4 and Figure 6 shown, there are four connecting rods 13. The pressing plate 30 is in a butterfly shape. Two of the connecting rods 13 are slidably connected to the pressing plate 30. The other two connecting rods 13 are located in the groove of the butterfly-shaped depression and are diagonally arranged with the connecting rods 13 sliding on the pressing plate 30. That is, two guiding holes 31 and two avoiding grooves 32 are arranged on the pressing plate 30, and the connecting rods 13 are located in the guiding holes 31 and the avoiding grooves 32.

[0043] Preferably, the pressing plate 30 is fixedly connected to the output end of the cylinder 20 through a threaded structure, and the axis of the cylinder 20 is parallel to the connecting rod 13.

[0044] As a preferred implementation manner in this embodiment, a guiding tube 40 is further fixedly connected to the main fixing plate 12. The seedling picking needle 50 is located in the guiding tube 40 and is slidably connected to the guiding tube 40. The guiding tube 40 is used to improve the stability of the seedling picking needle 50.

[0045] The guiding tube 40 is in a cylindrical shape with openings at both ends. The guiding tube 40 is fixed to the main fixing plate 12 by interference fit or threaded connection.

[0046] In this embodiment, there are four seedling picking needles 50. A pressing head 51 is arranged at one end of the seedling picking needle 50 close to the cylinder 20. The pressing head 51 is fixed to the end of the seedling picking needle 50 by threading or interference fit. The outer diameter of the pressing head 51 is larger than the outer diameter of the seedling picking needle 50. Both ends of the compression spring 60 are respectively abutted against the end of the guiding tube 40 and the pressing head 51.

[0047] Both the cylinder fixing plate 11 and the main fixing plate 12 are square plate-shaped. Through-hole structures for installing the connecting rod 13 and the cylinder 20 are arranged on the cylinder fixing plate 11 and the main fixing plate 12. An inclined hole structure for installing the guiding tube 40 is arranged on the connecting rod 13.

[0048] The four seedling picking needles 50 form an inverted quadrangular prism structure with one end large and one end small, which is the same as the shape of the substrate block. The included angle of the inverted quadrangular prism can prevent the substrate block from falling during transplantation.
