[0026] like Figure 1 As shown, a transplanter-linked seedling-grabbing device includes an upper seat plate 1, a seedling-grabbing claw bracket 2 slidably mounted on the bottom surface of the upper seat plate 1, and a seedling-grabbing claw assembly 3 slidably mounted on the seedling-grabbing claw bracket 2. The sliding directions of the seedling-grabbing claw bracket 2 and the seedling-grabbing claw assembly 3 are perpendicular to each other, and it is used to grab multiple seedlings at one time for transfer.
[0027] A support drive cylinder 4 is installed on the front side of the seedling claw support 2 to drive the seedling claw support 2 to move and realize the transfer of seedlings. A swing drive cylinder 5 is installed at the bottom of the seedling claw support 2 to drive the seedling claw assembly 3 to swing back and forth to realize the removal and placement of seedlings.
[0028] like Figure 2-3 As shown, two first slide rails 8 are arranged on the bottom surface of the upper seat plate 1 along the front-back direction. The two first slide rails 8 are fixedly installed near the two ends of the upper seat plate 1. The seedling claw support 2 includes a second slide rail 202, which is arranged along the left-right direction. At the two ends of the second slide rail 202, a first slider 201 is fixedly connected to the corresponding position of the first slide rail 8. The cross section of the first slider 201 is adapted to the shape of the slide groove of the first slide rail 8. The first slider 201 is slidably installed on the first slide rail 8, so that the seedling claw support 2 can slide along the front-back direction.
[0029] The bracket drive cylinder 4 is fixedly installed on the bottom surface of the upper seat plate 1. In this embodiment, the fixed end of the bracket drive cylinder 4 is fixedly installed on the bottom surface of the upper seat plate 1 near the front end, and the telescopic end is fixedly connected to the second slide rail 202 of the seedling claw bracket 2. The telescopic end of the bracket drive cylinder 4 extends and retracts, driving the seedling claw bracket 2 to move back and forth along the first slide rail 8.
[0030] In addition to this embodiment, the support drive cylinder 4 can also be replaced by an electric cylinder or a hydraulic cylinder. The movement of the extension and retraction end of the electric cylinder or hydraulic cylinder drives the seedling claw support 2 to move back and forth.
[0031] The seedling claw support 2 also includes a swing support 204. The two swing supports 204 are respectively fixedly connected to the two ends of the second slide rail 202. A third slide rail 203 is provided below the second slide rail 202. The two ends of the third slide rail 203 are respectively hinged to the bottom ends of the two swing supports 204. A swing arm 6 is fixedly connected to one end of the third slide rail 203. The end of the swing arm 6 away from the third slide rail 203 is hinged to the telescopic end of the swing drive cylinder 5. The fixed end of the swing drive cylinder 5 is hinged to the upper seat plate 1.
[0032] Specifically, a rotating shaft is fixedly connected to each end of the third slide rail 203. The rotating shaft is rotatably connected to the swing brackets 204 at both ends through bearing seats. The swing arm 6 is fixedly installed at one end of one of the rotating shafts located outside the swing bracket 204. Pushing the swing arm 6 allows the third slide rail 203 to rotate on the swing bracket 204.
[0033] In this embodiment, a number of mounting holes are evenly spaced on the swing arm 6. The telescopic end of the swing drive cylinder 5 is installed in different mounting holes, which can adjust the swing angle of the third slide rail 203. In addition to this embodiment, an elongated hole can also be opened on the swing arm 6. The elongated hole is arranged along the axial direction of the rotating shaft. By adjusting the installation position of the telescopic end of the swing drive cylinder 5, the swing angle of the third slide rail 203 can be infinitely adjusted.
[0034] In addition to this embodiment, the swing drive cylinder 5 can also be replaced by an electric cylinder or a hydraulic cylinder to drive the third slide rail 203 to swing.
[0035] To enhance the structural strength of the seedling claw support 2, a reinforcing crossbeam 205 is provided between the second slide rail 202 and the third slide rail 203. The two ends of the reinforcing crossbeam 205 are fixedly connected to the swing supports 204 on both sides.
[0036] Two seedling-picking claw components 3 are symmetrically slidably mounted on the third slide rail 203. Each seedling-picking claw component 3 includes several grippers 301. The number of grippers 301 can be adjusted according to the number of seedlings in each row of the seedling tray used in the matching process. The two adjacent grippers 301 and the two seedling-picking claw components 3 are interconnected and the spacing between them is adjustable to achieve linkage.
[0037] In this embodiment, a slider is fixedly connected to the top of the gripper 301, and a groove is provided on the bottom surface of the third slide rail 203 at a position corresponding to the slider, and the slider is slidably installed in the groove.
[0038] In this embodiment, the seedling gripper assembly 3 is provided with a first gripper, a second gripper, a third gripper and a fourth gripper in sequence from the end near the third slide rail 203. A connecting rod 305 is provided between the first gripper and the second gripper. The connecting rod 305 is arranged parallel to the third slide rail 203. One end of the connecting rod 305 is fixedly connected to the second gripper, and the other end is provided with an elongated hole. The first gripper is slidably installed in the elongated hole.
[0039] Similarly, a connecting rod 305 is also provided between the second and third grippers, and between the third and fourth grippers. In order to realize the linkage between the two seedling picking claw assemblies 3, a connecting rod 305 is also provided between the fourth grippers of the two seedling picking claw assemblies 3.
[0040] A spring 306 is also provided between the second and fourth grippers in one of the seedling-picking claw components 3, and between the fourth gripper and the third gripper of the other seedling-picking claw component 3. The two ends of the spring 306 are respectively hooked to the fixing plates of the two grippers 301. When the seedling-picking claw component 3 moves backward, the grippers 301 slide towards both ends of the third slide rail 203, at which time the spring 306 is stretched. When the seedling-picking claw component 3 moves forward, the grippers 301 converge towards the middle part of the third slide rail 203, and the restoring force of the spring 306 drives the grippers 301 back to their original position.
[0041] In this embodiment, the gripper 301 is a mature structure in the prior art. By controlling the opening and closing of the gripper arms on both sides of the gripper 301, the seedlings can be picked up and placed. The specific structure will not be described in detail in this application.
[0042] In the seedling claw assembly 3, a sliding bracket 302 is hinged to the rear side of the gripper 301 near the end of the third slide rail 203. A sliding block 303 is hinged to the top of the sliding bracket 302. The sliding block 303 is slidably mounted on the second slide rail 202. A guide wheel 304 is rotatably connected above the sliding block 303 via a bearing.
[0043] A guide groove 7 is provided on the upper plate 1 at the position corresponding to the two guide wheels 304. The guide wheels 304 are slidably installed in the guide groove 7. The seedling claw bracket 2 moves back and forth, driving the guide wheels 304 to move along the guide groove 7. By adjusting the shape of the guide groove 7, the guide wheels 304 can move in the left and right directions, thereby driving the seedling claw assembly 3 to move left and right, so as to transport the seedlings to different positions.
[0044] Initially, the support drive cylinder 4 is located at the front end of the upper seat plate 1, and the gripper 301 in the seedling claw assembly 3 is gathered at the middle position of the seedling claw support 2, with the gripper 301 corresponding to the position of the seedling on the seedling tray.
[0045] After the drive gripper 301 clamps the seedling, the swing drive cylinder 5 is activated, which drives the third slide rail 203 to swing forward, raising the seedling to remove it from the seedling tray. Then, the bracket drive cylinder 4 is activated, which pushes the seedling claw bracket 2 to move the seedling claw assembly 3 backward. At the same time, under the drive of the guide wheel 304, the gripper 301 slides along the third slide rail 203 to place the seedling in the seedling box for the next step.
[0046] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
