[0002] The seedling taking claw is a core component of the seedling taking mechanism of the transplanter, and the main function of the seedling taking claw is that when a row of seedlings in a plug tray placed on the conveying mechanism reaches a seedling taking point, that is, the row of seedlings is located below the seedling taking claw, the seedling taking mechanism drives the seedling taking claw to vertically insert and clamp the pot seedlings in the plug tray, the pot seedlings are extracted from the plug tray, and then the pot seedlings are stably transported to a seedling dropping point and dropped into the seedling separating mechanism or the planting device. The whole seedling taking process includes the steps of clamping seedlings, taking seedlings, and dropping seedlings, and the seedling taking claw is required to accurately take out the pot seedlings without damaging or crushing the pot body, to have sufficient clamping force to ensure that the seedlings are not dropped during the movement to the next step, and to ensure that the pot seedlings are completely separated from the seedling taking claw and vertically dropped into the seedling separating mechanism or the planting device during the seedling dropping process.

[0003] In the prior art, for young seedlings with a large leaf width, the seedling taking claw adopts a vertical downward insertion and clamping mode, which may cause damage to the branches and leaves, and in addition, the four needles may also cause damage to the roots during clamping, which has certain limitations.

[0013] Figure 2 is a structure schematic view of the seedling taking mechanism comprising the seedling taker. DETAILED DESCRIPTION

[0014] The utility model will be further explained in combination with the drawings and specific embodiments. It should be understood that these embodiments are only used for illustrating the utility model, and are not used for limiting the scope of the utility model, and after reading the content of the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms are also within the range defined by the utility model.

[0015] As Figure 1As shown, a finger-type seedling picker includes a cylinder 1, a mounting plate 2, a picking needle lever 3, a picking needle 4, a seedling pushing ring 5, and a seedling pushing ring bracket 6. The cylinder 1 is fixedly mounted on the upper surface of the triangular mounting plate 2. A picking needle lever 3 is hinged to each of the three sides, and the line connecting the three picking needle levers 3 forms a first equilateral triangle. A picking needle 4 is fixedly connected to the lower surface of each picking needle lever 3. The three picking needles 4 pass through the seedling pushing ring 5, which is spherical or shaped like a ball. The seedling pusher ring 6 has three through holes. A spherical or chess-shaped pusher ring 5 rotates within these holes. The free end of the cylinder piston rod is connected to the pusher ring 6. The line connecting the three clamping needles 4 on the pusher ring 6 forms a second equilateral triangle, with a side length shorter than the first equilateral triangle. The cylinder's extension and retraction move the pusher ring 6 along the clamping needles 4, thus adjusting the opening and closing of the seedling-grabbing claw composed of the three needles 4. The three-needle claw provides more stable gripping and reduces damage to the roots when handling potted seedlings.

[0016] The mounting plate 2 is preferably equilateral triangle in shape, and a needle-clamping lever 3 is hinged to the middle of each of the three sides of the equilateral triangle mounting plate 2 to facilitate installation.

[0017] The shape of the seedling pusher ring bracket 6 can be triangular, circular, square, etc., as long as the line connecting the three clamping needle through holes on the seedling pusher ring bracket 6 forms an equilateral triangle. The shape of the seedling pusher ring bracket 6 is preferably an equilateral triangle or a circle.

[0018] like Figure 2 As shown, a seedling-picking mechanism including finger-type seedling pickers includes a frame. A sliding arm cylinder 13 and a landing gear cylinder 17 are fixedly mounted on the frame. The landing gear cylinder 17 is fixedly connected to a landing gear 12, which is fitted at its four corners onto four support pillars 11. The landing gear cylinder 17 drives the landing gear 12 to slide vertically on the support pillars 11. The sliding arm cylinder 13 is fixedly connected to a sliding arm 16, whose two ends are slidably connected to the landing gear 12. The sliding arm cylinder 13 drives the sliding arm 16 to slide laterally on the landing gear 12. A sliding rail 14 is fixedly connected to the lower surface of the sliding arm 16, and six finger-type seedling pickers 10 are slidably connected to the sliding rail 14. Each finger-type seedling picker 10 has an angle of 60° with the horizontal plane. By picking up seedlings from the pot by inserting them obliquely from the side, damage to the seedling's branches and leaves can be reduced or even avoided.

[0019] The sliding arm cylinder 13 and the landing gear cylinder 17 can also be replaced with hydraulic cylinders or electric push rods.

[0020] A limiting block 15 is provided at the top of the strut 11. The limiting block 15 can prevent the landing gear 12 from moving excessively vertically.

[0021] Work process:

[0022] The working mode of taking seedlings and planting seedlings at the same time is that six seedling taking claws are installed on the sliding rail 14, the landing gear 12 is driven to move vertically by the landing gear cylinder 17, the sliding arm 16 is driven to move horizontally by the sliding arm cylinder 13, the seedling taking claws are brought to the seedling taking point above the plug tray 9, the seedling taking claws always keep a 60° angle with the plane, then the landing gear 12 is driven to move downward by the landing gear cylinder 17 again, the seedling taking claws composed of three clamping pins 4 are driven to take seedlings and clamp seedlings by the seedling taking claw cylinder 1, after the clamping process is completed, the landing gear 12 is driven to move upward by the landing gear cylinder 17, the sliding arm 16 is driven to move backward by the sliding arm cylinder 13, the seedling taking mechanism is prepared to take seedlings, and after the seedling taking claws move to the seedling planting point above the seedling cup 8, the seedling planting action is completed. The whole process includes taking seedlings, clamping seedlings, taking seedlings, and planting seedlings.

[0023] If the spacing of the six seedling taking claws is inconsistent with the spacing of the seedling cups 8, the spacing of the six seedling taking claws can be adjusted. For example, the six seedling taking claws are connected through a scissor fork type connecting piece, one power is used to drive the seedling taking claws to move left and right on the sliding rail, the spacing of the six seedling taking claws is adjusted, and the six seedling taking claws accurately reach above the seedling cups. The connection between the seedling taking claws through the scissor fork type connecting piece is prior art, and can be referred to the Chinese patent with the application number 202321564917.5. The seedling taking claws can also be connected through other connecting structures, such as the Chinese patent with the application number 202321564923.0.

[0024] The preferred embodiments of the present application are described above, it should be noted that for those skilled in the art, without departing from the overall concept of the present application, a number of changes and improvements can be made, which should be considered as the protection range of the present application.
