Description

Technical Field

[0001] The utility model relates to the technical field of seedling transplanting, and more specifically, to a seedling picking mechanism for a plug tray. Background Art

[0002] During breeding, seeds are first planted in a seedling tray. The seedling tray is provided with a number of uniformly sized seedling grooves. The seeds are sown in the seedling grooves until they take root. During this process, the root systems will cause the soil matrix in the seedling grooves to bind tightly. Since the spacing between adjacent seedling grooves in the breeding tray is small, after breeding is completed, it is necessary to replant them with roots and soil into a plug tray with a larger space. This operation is called transplanting. Common application ranges include fruit and vegetable seedlings, flowers, Chinese medicinal materials, etc. The purpose of transplanting is to ensure an appropriate space to promote the rooting and growth of plants.

[0003] In a large-scale planting scenario, the transplanting work is often completed by a transplanting robot. The specific process is that the raw seedlings are conveyed by a raw seedling conveyor belt to the area to be processed. The picking module is driven by a moving module to reach above the seedling tray, and the whole row of seedlings is grabbed at one time. After the grabbing is completed, it moves above the planting plug tray and plants the raw seedlings into the planting plug tray.

[0004] The key structure of the picking module is the picking clip. The existing picking clip structure cannot be adapted to the shape of the seedling groove when extracting seedlings. Since the soil matrix is fragile and easy to scatter, the seedlings are easily separated from the original soil matrix during extraction, resulting in the failure of seedling extraction and even affecting the survival rate of the seedlings after transplantation.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0021] like Figures 1-3 As shown, the technical solution of the utility model provides a seedling tray taking mechanism, including a fixed bracket, a clamping assembly 3 and a driving assembly 4 arranged on the fixed bracket; the fixed bracket includes a cantilever fixed plate 1 and a clamping fixed plate 2. Figures 1-2As shown, the seedling picking structure is arranged on the seedling picking module 5, and is driven by the motion module to reach the designated seedling picking position. The driving component 4 and the clamping and grasping component 3 are both installed on the clamping and grasping fixing plate 2.

[0022] The clamping assembly 3 includes a horizontal portion 31 and two clamping portions located on both sides of the horizontal portion 31. The two clamping portions are arranged to be tilted and gathered. The clamping portions are made of elastic material. The driving assembly 4 drives the two clamping portions to deform to an open or gathered state. The horizontal portion 31 is connected to the clamping fixing plate 2. The clamping portions are in a gathered state in a natural state. The clamping portions are driven by the driving assembly 4 to deform and open. When the clamping portions are inserted into the seedling raising groove, the driving assembly 4 is reset. The clamping portions are deformed back to the gathered state and the seedlings are clamped together with the soil matrix.

[0023] The clamping part of this solution is made of deformable material, and its shape is similar to that of the seedling trough. It can change with the angle of the seedling trough to achieve wrapping clamping of the seedlings and soil matrix, ensure the clamping stability and integrity, and avoid loosening of the soil matrix.

[0024] The clamping part includes a plurality of clips 32 arranged at intervals, and the clips 32 are integrally connected to the horizontal part 31. The free end of the clip 32 is a pointed head. The clip 32 is an elastic steel sheet. The clip 32 is set as a pointed head to facilitate insertion into the soil matrix. The thickness of the clip 32 is not too thick to avoid affecting the elasticity, and is preferably about 3 mm.

[0025] The driving assembly 4 includes a push cylinder 41 and a push block 42 connected to the output end of the push cylinder 41. The push block 42 is provided with a slot 43 corresponding to the clamp 32, and the clamp 32 is arranged through the slot 43. The output end of the push cylinder 41 passes through the horizontal part 31 and is connected to the push block 42. The push block 42 is located below the horizontal part 31. When the push cylinder 41 drives the push block 42 downward, the clamping part opens, and vice versa. The push block 42 is provided with a clearance notch 44. The setting of the clearance notch 44 avoids damage to the seedlings when clamping the seedlings.

[0026] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
