[0002] Sea cucumbers are considered one of the "Eight Delicacies" (or "Deities"), and they possess a strong regenerative capacity. Living on the pristine seabed, they are known as the "God of Longevity." They are both a feasting delicacy and a nourishing tonic. They are a typical high-protein, low-fat, and low-cholesterol food, with delicate, easily digestible flesh rich in eight amino acids that the human body cannot synthesize. Currently, sea cucumber aquaculture primarily relies on shallow-water raft-type cages. Traditionally, cage cleaning and feeding are performed manually. This involves rotating and oscillating the cages back and forth in seawater to remove debris and food residue. During feeding, the cages are lifted onto a bamboo raft, opened one by one, and bait is introduced. Manual cleaning and feeding can lead to uneven feeding, inadequate cage cleaning, low efficiency, and dangerous operations. Summary of the Invention

[0027] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] like Figure 1 ~As shown in the figure, a sea cucumber feeding device includes a frame 100 provided with a crawler walking device 200, a pair of beams 300 extending to the left and right sides respectively are symmetrically arranged above the frame, and a plurality of retractable vertical operating arms 400 are arranged at intervals along the length direction and can move laterally are arranged below the beams, and a pair of claws 800 for cooperating to grasp the breeding cage are connected to the lower end of the operating arm. A plurality of bait storage troughs are provided on the beam 300, and a pushing mechanism 310 is provided on one side of the bait storage trough and a feeding tube 320 is connected on the other side. Each bait storage trough corresponds to an operating arm, and each bait storage trough is equipped with an independent pushing mechanism 310 and a feeding tube 320. The lower end of the feeding tube 320 extends to the vicinity of the feeding hole on the side of the breeding cage so that after the operating arm drives the breeding cage 700 to move laterally, the lower end of the feeding tube can extend into the feeding hole. This device is equipped with multiple operating arms, which extend below the sea surface during operation and then grab the cage through the end claws. The position of the feeding tube is relatively fixed. The operating arm drives the breeding cage to move laterally so that the feeding tube 320 extends into the feeding hole. Then the pushing mechanism pushes the bait in the bait storage trough so that the bait enters the breeding cage through the feeding tube 320. After feeding is completed, the operating arm drives the breeding cage to move laterally in the opposite direction, and the feeding tube 320 is separated from the feeding hole. The sea cucumber bait feeding device realizes mechanical feeding, replaces traditional manual feeding, reduces labor costs, thereby improving operation efficiency and reducing sea cucumber breeding costs.

[0030] In this embodiment, the pushing mechanism 310 includes a support 311 fixedly connected to the beam frame and a pushing plate 312 located in the bait storage tank. A servo motor 313 for controlling feeding is installed on the support. A first nut seat 314 is fixedly connected to the side wall of the bait storage tank facing the servo motor. A first screw rod 315 is passed through the first nut seat and is threadedly engaged with the first nut seat. The inward end of the first screw rod is rotatably connected to the pushing plate, and the outward end is connected to the servo motor through a belt 316 and a pulley. The breeding cage has a multi-layer structure, and each bait storage trough is also connected to a feeding tube with the same number of layers as the breeding cage. The discharge end of the feeding tube corresponds to the feeding hole position of each layer. When the push plate moves toward the side where the feeding tube is located, the bait is squeezed out of the feeding tube. The push plate stroke is controlled by the screw rod to accurately and quantitatively feed the bait into each cage, thereby achieving precise feeding, which not only improves the maximum utilization rate of the bait, but also ensures that there is no missed feeding or overfeeding during the feeding process.

[0031] In this embodiment, the operating arm 400 is a retractable structure, and a movable slide 330 is installed above each operating arm on the bottom side of the beam frame. The upper end of the operating arm is fixedly connected to the slide seat of the movable slide 330, and the movable slide 330 is an electric screw movable slide.

[0032] In this embodiment, the operating arm 400 includes a machine base 410 at the upper end and a hollow fixed rod 420 fixedly connected to the lower side of the machine base, and the lower part of the fixed rod is sleeved with a movable rod 430 that can slide up and down relative to it; a control motor 440 is installed on the machine base, and a second screw rod 450 is provided inside the fixed rod, and the upper end of the second screw rod is rotatably connected to the machine base, and the upper end of the movable rod is fixedly connected to a second nut seat 460 that cooperates with the second screw rod thread, and the control motor is connected to the upper end of the second screw rod through the transmission gear set 470; the control motor 440 drives the second screw rod 450 to rotate and thereby changes the up and down movement of the movable rod 430 to realize the extension and retraction of the operating arm.

[0033] In this embodiment, in order to prevent the movable rod from rotating together with the second screw rod, a limit rod 480 parallel to the fixed rod or the movable rod is fixedly connected to the machine base, and the lower end of the movable rod is fixedly connected to a fixed limit plate 490, and a limit hole is provided on the limit plate for the limit rod to pass through.

[0034] In this embodiment, the lower end of the operating arm 400 is connected to a rotary servo 500, the rotary shaft of which is connected to a claw-clip connecting frame 600. The claws 800 are hinged to the claw-clip connecting frame 600, and the paired claws are provided with meshing synchronous gears 810 at their hinged portions. The claw-clip connecting frame is equipped with a claw-clip servo 610, which drives the claws in rotation. The extension and retraction of the operating arm drives the vertical movement of the aquaculture cage, while the rotary servo 500 drives the rotation of the aquaculture cage. This combination of rotation and vertical movement allows the cage to be cleaned in seawater, replacing manual cleaning with mechanical cleaning, which improves cleaning efficiency and reduces labor intensity.

[0035] In this embodiment, the beam is connected to the frame through a support column 340 toward the middle end, and a retractable support rod 350 is connected to the lower side of the beam away from the middle end. The support rod 350 is composed of an upper fixed tube and a lower telescopic rod. The fixed tube is sleeved on the upper part of the telescopic rod and the two are engaged by a thread. When the telescopic rod is rotated, the telescopic rod will extend downward.

[0036] In this embodiment, a crawler walking device 200 is used to improve adaptability to uneven roads. The width of the crawler increases the contact area with the road surface and reduces the risk of driving into the sea. A tracking template can be equipped in the control system to allow the vehicle to travel unmanned along the tracking route, which not only ensures the safety of the entire vehicle but also improves operating efficiency.

[0037] In this embodiment, the crawler walking device 200 belongs to the existing technology, and its structure and principle are not elaborated in detail here. It mainly includes a crawler 210, a driving wheel 220, a tensioning wheel 230, a sprocket wheel 240, a supporting wheel 250, a supporting wheel bracket 260, and a tensioning mechanism 270.

[0038] In this embodiment, a chassis 110 and an electric control box 120 are provided on the frame, and a display screen 111 is provided on the chassis 110 .

[0039] A working method of the sea cucumber bait feeding device as described above comprises the following steps:

The cage on one side is cleaned in all directions with sea water. After cleaning the cage on one side, the rotating steering gear rotates the claw clamp 180 degrees. oThen hold the cage on the other side tightly, and then perform the same operation to clean the cage on the other side in all directions;

[0042] (3) Then, the feeding operation is carried out. The prepared bait is placed in the bait storage tank at the upper end. The cleaned hanging cage is lifted by the operating arm. Then, the movable slide on the beam frame drives the hanging cage to move horizontally through the operating arm, so that each feeding tube is inserted into the corresponding feeding hole on the side of the hanging cage; then the servo motor drives the push plate in the bait storage tank to move, pushing the bait into the feeding tube and sending it into the hanging cage;

[0043] (4) After feeding is completed, the movable slide on the beam frame drives the cage to move horizontally in the opposite direction through the operating arm, so that the cage is pulled out of the feeding hole in the feeding tube. The operating arm puts the cage back into the sea water, the claw clamp is released, the operating arm is retracted and the support rod is retracted, completing the operation; the feeding device moves to the next operation area and operates the entire aquaculture area in turn.
