Description

Technical Field

[0001] The utility model belongs to the field of fishery machinery, and in particular relates to a seedling clamping device for clamping kelp seedlings onto a seedling rope. Background Art

[0002] As an important seaweed organism, kelp has extremely high edible and industrial value. Since kelp farming has obvious seasonal characteristics, if the early kelp seedlings cannot be clamped on the seedling rope in time, it will hinder the later seedling separation work, which will directly affect the yield of cultivated kelp.

[0003] At present, in the process of kelp cultivation, the kelp seedlings are usually clamped onto the seedling rope by manual clamping: first a small opening is made in the seedling rope, and then the kelp seedlings are placed into the opening, and this process is repeated, which is labor-intensive and inefficient.

[0004] In order to improve efficiency, a mechanized seedling clamping solution has been proposed in the prior art. For example, the Chinese utility model patent with the authorization announcement number CN201467785U discloses a kelp planting rope splitting and seedling clamping machine, which uses two staggered pins to pry apart the two strands of the seedling rope to create a gap, thereby facilitating the kelp seedlings. However, this method has the problems of complex transmission structure and easy jamming, and the pins are easy to damage the seedling rope. Utility Model Content

[0025] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0026] like Figure 1 and 2 A pneumatic kelp seedling clamping device comprises a frame 1, on which a seedling dropping device 3, a rotating air claw 2, a clamping air claw 4, a rope winding mechanism 6 and a guiding mechanism are installed.

[0027] The guiding mechanism comprises two groups of left and right support rods 5, and the front ends of the support rods 5 are provided with hooks for placing the seedling ropes.

[0028] The seedling dropping device 3 is located above the guiding mechanism. Specifically, the seedling dropping device 3 includes a seedling bin 3-1 installed on the frame 1, and the bottom of the seedling bin 3-1 is funnel-shaped and the cross-sectional area gradually decreases. A roller 3-2 is provided on the side wall corresponding to the bottom outlet of the seedling bin 3-1, and the roller 3-2 and the opposite side wall form a narrow seedling dropping channel. A first motor 3-3 for driving the roller 3-2 to rotate is also installed on the seedling bin 3-1. The first motor 3-3 is preferably a stepping motor, and each time it rotates, a slender kelp seedling falls from the outlet.

[0029] The rope winding mechanism 6 is used to wind the seedling rope so that the seedling rope moves along the guide mechanism. Specifically, the rope winding mechanism 6 includes a rope drum 6-1 installed on the frame 1 and located below the guide mechanism, and also includes a second motor 6-2 installed on the frame 1 and used to drive the rope drum 6-1 to rotate. The second motor 6-2 is preferably a stepping motor, and each time it rotates, the distance the seedling rope travels is equal to the spacing between the clamped seedlings.

[0030] Furthermore, the rope drum 6-1 is mounted on the frame 1 via a rotating shaft and can be removed as a whole. At the same time, the front and rear parts of the rope drum 6-1 are also detachable.

[0031] The rotating air claw 2 and the clamping air claw 4 are both used to clamp the seedling rope, and the clamping points of the two are respectively located on both sides below the outlet.

[0032] The rotating air gripper 2 and the clamping air gripper 4 are both common pneumatic actuators. The rotating air gripper 2 comprises a body, a rotating part and a clamping part, wherein the body is mounted on the frame 1, the rotating part is mounted on the body and rotates relative to the body, and the clamping part is mounted on the rotating part.

[0033] Furthermore, the clamping air claw 4 is located between the two groups of supporting rods 5. After the seedling rope passes horizontally through the supporting rod 5 on the left, the clamping air claw 4 and the supporting rod 5 on the right in sequence, it is bent downward and wound onto the rope winding mechanism 6. The rotating air claw 2 is installed on the right side of the supporting rod 5 on the right side, and its clamping claw part extends to the left to clamp the bend.

[0034] Furthermore, an air pump 7 for providing compressed air to the rotating air claw 2 and the clamping air claw 4 is also installed on the frame 1 .

[0035] During operation, the kelp seedlings are first placed in the seedling bin 3-1, and then the rope winding mechanism 6 is activated to make the seedling rope travel a certain distance. At this time, the current seedling clamping point on the seedling rope is just below the exit of the seedling dropping device 3. Then the rotating air claw 2 and the clamping air claw 4 are activated to clamp the seedling rope from both sides, and then the rotating air claw 2 is rotated by an angle (generally less than 180 degrees) to form an opening at the seedling clamping point, and then the roller 3-2 is activated to make a section of kelp seedlings fall into the opening. After that, the rotating air claw 2 rotates in the opposite direction, the opening is closed, and the kelp seedlings are clamped. Then the rotating air claw 2 and the clamping air claw 4 release the seedling rope, wait for the rope winding mechanism 6 to act again, and start the seedling clamping operation at the next seedling clamping point, and repeat this action. After the seedling clamping is completed, the entire rope drum 6-1 is removed, and then the seedling rope with the kelp seedlings is removed.

[0036] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
