Description

Technical Field

[0001] The utility model belongs to the technical field of transfer clamping of grafting machines, in particular to an automatic seedling pulling mechanism for melon seedlings. Background Art

[0002] Cucurbit grafting is an effective propagation method for improving the yield and quality of melons and fruits. Grafting melons can enhance disease resistance and drought tolerance, thereby improving the quality and yield of melons and fruits. Cucurbit grafting utilizes the ability of melon plants to graft onto each other, joining two different melon plants together to create a new one.

[0003] Existing grafting machines typically feature a fixed V-shaped jaw at the top and bottom, used to align and grip the rootstock or scion being transferred. In practice, melon seedlings can bend or tilt during growth, hindering subsequent transfer steps such as loading and positioning, and thus reducing transfer efficiency.

[0004] For this reason, we propose a melon seedling automatic pulling mechanism to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that seedlings are bent or skewed, which affects the subsequent transfer efficiency, and proposes an automatic seedling straightening mechanism for melon seedlings.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An automatic melon seedling straightening mechanism comprises a base, a workbench slidably provided on the upper end of the base, a mounting plate rotatably provided on one side of the top surface of the workbench, an electric push rod for driving the mounting plate to rotate installed on the other side, a telescopic cylinder fixedly installed on the top surface of the mounting plate, and a movable plate for linear motion driven by the telescopic cylinder installed on the top surface of the telescopic cylinder;

[0008] A clamping cylinder is fixedly installed at one end of the movable plate, and transfer claw seats that move towards or away from each other are fixedly installed at both ends of the clamping cylinder. V-shaped transfer clamps are fixedly connected to the opposite sides of the upper ends of the two transfer claw seats, and a seedling straightening cylinder is fixedly installed at the lower end of the transfer claw seat. A straightening clamp is provided slidingly below the transfer clamp and moves up and down relying on the seedling straightening cylinder.

[0009] Preferably, the two transfer jaws are staggered, and a stopper is fixedly connected to the V-shaped tip of the transfer jaw, and the stopper of the upper transfer jaw is located on its bottom surface, and the stopper of the lower transfer jaw is located on its top surface.

[0010] Preferably, an extension plate is fixedly connected to one side of the transfer clamping jaw close to the clamping cylinder, and the two extension plates are always in a staggered state during the movement.

[0011] Preferably, the sides of the two transfer clamps facing each other, the sides of the two straightening clamps facing each other, and the sides of the extension plate are all rounded.

[0012] Preferably, a lifting assembly for driving the workbench to adjust and move up and down is fixedly mounted on the lower end of the base.

[0013] Preferably, one end of the electric push rod is hinged to the mounting plate, and the other end is hinged to the workbench.

[0014] To sum up, the technical effects and advantages of the utility model are as follows: compared with the existing device, the automatic straightening mechanism for melon seedlings drives the two transfer claw seats to approach each other through the clamping cylinder, so that the two transfer claws can position and clamp the melon seedlings, and then cooperate with the two straightening cylinders to drive the two straightening claws to move downward, so that the straightening claws can straighten the bent or skewed embryonic axis. Compared with the existing device, it avoids the problem of seedlings bending or skewness affecting subsequent transfer, and improves the transfer efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-3 An automatic melon seedling straightening mechanism comprises a base 1 with a workbench 2 slidably mounted on its upper end. A mounting plate 3 is pivotally mounted on one side of the top surface of the workbench 2, and an electric push rod 4 is mounted on the other side to drive the mounting plate 3 in rotation. A telescopic cylinder 5 is fixedly mounted on the top surface of the mounting plate 3, and a movable plate 6 is mounted on the top surface of the telescopic cylinder 5 for linear motion.

[0024] A clamping cylinder 7 is fixedly mounted on one end of the movable plate 6, and transfer claw seats 8 are fixedly mounted on both ends of the clamping cylinder 7 so as to move closer to or away from each other. A V-shaped transfer clamping claw 9 is fixedly connected to the opposite side of the upper end of the two transfer claw seats 8, and a seedling straightening cylinder 10 is fixedly mounted on the lower end of the transfer claw seat 8. A straightening clamping claw 11 is slidably provided below the transfer clamping claw 9 and moves up and down by relying on the seedling straightening cylinder 10.

[0025] In this utility model, the transfer jaw 9 is fixed to the transfer jaw seat 8, and the straightening jaw 11 is a movable jaw with a fixed stroke. Its clamping mouth is a smooth circular structure, slightly larger than the diameter of the seedling. After receiving the seedling, the clamping cylinder 7 drives the two transfer jaw seats 8 to move closer to each other, and the two transfer jaws 9 then move closer to each other. Their V-shaped structure corrects the deviated hypocotyl to the specified position and enters the restricted range of the straightening jaw 11. The transfer jaws 9 move closer to each other and clamp the hypocotyl.

[0026] At this time, the telescopic cylinder 5 drives the movable plate 6 to move, and the closed transfer jaws 9 and straightening jaws 11 retract along with the movable plate 6. The electric push rod 4 then drives the movable plate 6 to rotate 90 degrees, and the movable plate 6 extends toward the turntable mechanism loading station. After extension, the two straightening cylinders 10 drive the two straightening jaws 11 to move downward simultaneously, completing the seedling pulling action. After the jaws of the turntable mechanism loading station are closed, the two transfer jaws 9 move away from each other along with the transfer jaw seat 8, and then retract and rotate to reset.

[0027] Reference Figure 5 The two transfer jaws 9 are staggered, with a stopper 12 fixedly connected to the V-shaped tip of the transfer jaw 9. The stopper 12 of the upper transfer jaw 9 is located on its bottom surface, and the stopper 12 of the lower transfer jaw 9 is located on its top surface. The stopper 12 cooperates with the transfer jaw 9 to ensure that the forces on both sides of the seedling are the same, preventing the seedling from being damaged by shear force and improving the clamping effect.

[0028] An extension plate 13 is fixedly connected to the side of the transfer clamping jaw 9 close to the clamping cylinder 7, and the two extension plates 13 are always in a staggered state during the movement process. This provides a limit for the seedlings, preventing the seedlings from being located outside the two transfer clamping jaws 9 after the moving plate 6 moves, thereby improving the clamping effect.

[0029] The facing sides of the two transfer clamping jaws 9, the facing sides of the two straightening clamping jaws 11 and the side of the extension plate 13 are all rounded to avoid damage to the seedlings by sharp edges during the clamping and straightening process.

[0030] Reference Figure 1 、 Figure 6 A lifting assembly 14 is fixedly installed at the lower end of the base 1, and the lifting assembly 14 includes a screw and a lifting motor. The screw is driven to rotate by the lifting motor, and the workbench 2 is fixedly connected to the slider moving on the screw, thereby realizing the lifting adjustment of the entire workbench 2.

[0031] Since the mounting plate 3 needs to rotate, the connection point between the electric push rod 4 and the mounting plate 3 will also rotate accordingly. Therefore, one end of the electric push rod 4 is hinged on the mounting plate 3 and the other end is hinged on the workbench 2.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
