Description

Technical Field

[0001] This utility model relates to the technical field of breeding net cages, specifically a seedling breeding net cage. Background Technology

[0002] A breeding net cage is a device that uses synthetic fiber netting or metal netting as materials, assembled into a box of a certain shape and size, and set in a suitable water body for breeding. Aquatic organisms are generally raised inside the breeding net cage during the seedling stage to improve the survival rate of the seedlings.

[0003] The patent application "CN213523482U" discloses a breeding net cage for redclaw crayfish larvae. This cage consists of a broodstock net cage, a larvae net cage, fixing rods, broodstock hiding places, larvae hiding places, and sinkers. The broodstock net cage is placed inside the larvae net cage. The broodstock hiding places are located inside the broodstock net cage, while the larvae hiding places are located in the larvae net cage area outside the broodstock net cage. This invention overcomes the shortcomings of high investment in redclaw crayfish breeding infrastructure and low breeding efficiency. It eliminates the need for infrastructure investment while achieving the same breeding effect as a redclaw crayfish breeding workshop, providing conditions for widespread application in redclaw crayfish farms of different scales and increasing breeding efficiency by more than 20%.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] Existing seedling breeding cages generally rely on manual feeding. During the feeding process, it is difficult to ensure that the feed is evenly distributed inside the cage. As a result, the seedlings cannot effectively consume the feed within a certain period of time, and the feed will deteriorate in the water, leading to a decrease in the survival rate of the seedlings. Utility Model Content

[0006] The purpose of this utility model is to provide a seedling breeding net cage to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A seedling breeding net cage includes a net cage body, with floats fixedly connected to both sides of the net cage body, a support frame fixedly connected to the top of the net cage body, a feed box disposed inside the support frame, a feed pipe fixedly connected to the bottom of the feed box via a solenoid valve, a diversion box fixedly connected to the bottom of the feed pipe, and a feed hole fixedly connected to the bottom of the diversion box.

[0009] The feeding mechanism is fixedly mounted on the support frame and is used to control the feed to fall evenly into the inside of the cage body at regular intervals.

[0010] A vibration mechanism is fixedly mounted on the distribution box to prevent feed from getting stuck in the feed hole when it falls.

[0011] Preferably, the feeding mechanism includes a motor fixedly installed on one side of the support frame, the output end of the motor extending into the interior of the support frame and fixedly connected to a lead screw, a transmission block being drivenly connected to the surface of the lead screw, and the bottom of the transmission block being fixedly connected to the top of the feed box;

[0012] A controller and a timer are fixedly installed on one side of the support frame.

[0013] Preferably, the vibration mechanism includes support plates fixedly connected to both sides of the diversion box. A linkage block is provided on the top of the support plate. A striking rod and a transmission rod are fixedly connected to the bottom of the linkage block. The bottom of the transmission rod extends through to the bottom of the linkage block and is fixedly connected to a first pressing block. Several second pressing blocks that cooperate with the first pressing blocks are fixedly connected to the top of the mesh box body. A tension spring is sleeved on the surface of the transmission rod. The top of the tension spring is fixedly connected to the bottom of the linkage block, and the bottom of the tension spring is fixedly connected to the top of the support plate.

[0014] Preferably, the bottom of the first extrusion block is arc-shaped, and both sides of the second extrusion block are sloping.

[0015] Preferably, sliding blocks are fixedly connected to both sides of the feed box, and the inner wall of the support frame is provided with sliding grooves that cooperate with the sliding blocks.

[0016] Preferably, one end of the lead screw is provided with a bearing, and is rotatably connected to the inner wall of the support frame through the bearing.

[0017] Preferably, the diversion box is dovetail-shaped.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, by setting a feeding mechanism, allows for the setting of a feeding time via a timer. When the specified time is reached, the timer sends a signal to the controller. The controller's built-in PLC module simultaneously starts the motor and solenoid valve. The feed pellets in the feed box then enter the distribution box through the feeding pipe, and subsequently fall into the interior of the net box body through multiple feeding holes. At the same time, the motor drives the lead screw to rotate, and the rotation of the lead screw also controls the reciprocating movement of the transmission block. The feed box, feeding pipe, and distribution box also reciprocate with the transmission block, ensuring that the feed pellets fall evenly into the net box. This allows the seedlings to consume the feed within a certain time, preventing the feed from spoiling in the water and thus improving the survival rate of the seedlings.

[0020] 2. By setting up a vibration mechanism, this utility model enables the first extrusion block in the vibration mechanism to move synchronously while the feeding mechanism controls the diversion box to move back and forth. When the arc-shaped part of the first extrusion block contacts the sloping part of the second extrusion block, the first extrusion block will drive the transmission rod, linkage block and striking rod to move upward due to the extrusion. When the first extrusion block moves to the point where it no longer contacts the second extrusion block, the tension generated by the tension spring will drive the linkage block and striking rod to suddenly return to their original position downward. The striking rod will hit the support plate to generate vibration, and the vibration force will be transmitted from the support plate to the diversion box. The vibration improves the fluidity of the feed pellets when they fall, thus avoiding blockage. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution:

[0029] Example 1:

[0030] A seedling breeding net cage includes a net cage body 1, with floats 2 fixedly connected to both sides of the net cage body 1, a support frame 3 fixedly connected to the top of the net cage body 1, a feed box 4 disposed inside the support frame 3, a feed pipe 5 fixedly connected to the bottom of the feed box 4 via a solenoid valve, a diversion box 6 fixedly connected to the bottom of the feed pipe 5, and a feed hole 7 fixedly connected to the bottom of the diversion box 6.

[0031] The feeding mechanism is fixedly mounted on the support frame 3 and is used to control the feed to fall evenly into the cage body 1 at timed intervals.

[0032] The vibration mechanism is fixedly installed on the diversion box 6 to prevent feed from getting stuck in the feed hole 7 when it falls.

[0033] The feeding mechanism includes a motor 8 fixedly installed on one side of the support frame 3. The output end of the motor 8 extends into the interior of the support frame 3 and is fixedly connected to a lead screw 9. A transmission block 10 is connected to the surface of the lead screw 9. The bottom of the transmission block 10 is fixedly connected to the top of the feed box 4.

[0034] A controller 11 and a timer 12 are fixedly installed on one side of the support frame 3;

[0035] In this embodiment, considering that seedling breeding net cages are generally fed manually, it is difficult to ensure that the feed is evenly distributed inside the net cage during the feeding process. Seedlings cannot effectively consume the feed within a certain period of time, and the feed will deteriorate in the water, resulting in a decrease in seedling survival rate. Therefore, by setting a feeding mechanism, the feeding time can be set by timer 12. When the timer 12 reaches the specified time, it will send a signal to controller 11. The built-in PLC module of controller 11 will simultaneously start motor 8 and solenoid valve. The feed particles in feed box 4 will enter the diversion box 6 through feeding pipe 5, and then fall into the net cage body 1 through multiple feeding holes 7. At the same time, motor 8 will drive lead screw 9 to rotate. While the lead screw 9 rotates, it will also control transmission block 10 to move back and forth. The feed box 4, feeding pipe 5 and diversion box 6 will also move back and forth with transmission block 10, so that the feed particles can fall evenly inside the net cage, thereby allowing the seedlings to consume the feed within a certain period of time, avoiding feed deterioration in the water, and thus improving the seedling survival rate.

[0036] Sliding blocks 20 are fixedly connected to both sides of the feed box 4, and sliding grooves 21 that cooperate with the sliding blocks 20 are opened on the inner wall of the support frame 3.

[0037] In this embodiment, by setting a sliding block 20 and a sliding groove 21, when the lead screw 9 drives the transmission block 10 and the feed box 4, the transmission block 10 and the feed box 4 can only move back and forth along the trajectory of the sliding groove 21 under the restriction of the sliding block 20, which plays the role of restricting the movement trajectory.

[0038] One end of the lead screw 9 is provided with a bearing 22, and is rotatably connected to the inner wall of the support frame 3 through the bearing 22;

[0039] In this embodiment, by setting the bearing 22, the lead screw 9 can be supported, and the lead screw 9 can only rotate around the bearing 22, thereby improving the smoothness and stability of the lead screw 9 during rotation.

[0040] The distributor box 6 is in the shape of a swallowtail.

[0041] In this embodiment, by setting up a diversion box 6, the diversion box 6 can be designed in a dovetail shape, so that the feed can be evenly fed into the mesh cage body 1 from multiple feed holes 7 during the feed falling process, thereby improving the uniformity of feed feeding.

[0042] Example 2:

[0043] Based on Embodiment 1, in this embodiment, the feeding mechanism can control the diversion box 6 to reciprocate, so that the feed can fall evenly from the feeding hole 7 into the inside of the mesh box body 1. However, considering that the feed particles may get stuck in the feeding hole 7 due to poor flowability during the falling process, the vibration mechanism in this application includes a support plate 13 fixedly connected to both sides of the diversion box 6. A linkage block 14 is provided on the top of the support plate 13. A striking rod 15 and a transmission rod 16 are fixedly connected to the bottom of the linkage block 14. The bottom of the transmission rod 16 extends through to the bottom of the linkage block 14 and is fixedly connected to a first extrusion block 17. Several second extrusion blocks 18 that cooperate with the first extrusion block 17 are fixedly connected to the top of the mesh box body 1. A tension spring 19 is sleeved on the surface of the transmission rod 16. The top of the tension spring 19 is fixedly connected to the bottom of the linkage block 14, and the bottom of the tension spring 19 is fixedly connected to the top of the support plate 13.

[0044] In this embodiment, by setting a vibration mechanism, while the feeding mechanism controls the diversion box 6 to move back and forth, the first extrusion block 17 in the vibration mechanism will also move synchronously. When the arc-shaped part of the first extrusion block 17 contacts the sloping part of the second extrusion block 18, the first extrusion block 17 will drive the transmission rod 16, the linkage block 14 and the striking rod 15 to move upward due to the extrusion. When the first extrusion block 17 moves to a point where it is no longer in contact with the second extrusion block 18, the tension generated by the tension spring 19 will drive the linkage block 14 and the striking rod 15 to suddenly return to their original position downward. The striking rod 15 will hit the support plate 13 to generate vibration. The vibration force will be transmitted from the support plate 13 to the diversion box 6. The flowability of the feed particles when they fall is improved by vibration, thus avoiding blockage.

[0045] The bottom of the first extrusion block 17 is arc-shaped, and both sides of the second extrusion block 18 are sloping.

[0046] In this embodiment, by setting a first extrusion block 17 and a second extrusion block 18, when the arc-shaped part of the first extrusion block 17 comes into contact with the sloping part of the second extrusion block 18, the first extrusion block 17 will drive the transmission rod 16, the linkage block 14 and the striking rod 15 to move upward due to the extrusion effect, thus playing a transmission role.

[0047] Working principle: The feeding time is set by the timer 12. When the timer 12 reaches the specified time, it will send a signal to the controller 11. The built-in PLC module of the controller 11 will start the motor 8 and the solenoid valve at the same time. The feed pellets in the feed box 4 will enter the diversion box 6 through the feed pipe 5, and then fall into the net box body 1 through multiple feed holes 7. At the same time, the motor 8 will drive the lead screw 9 to rotate. While the lead screw 9 is rotating, it will also control the transmission block 10 to move back and forth. The feed box 4, feed pipe 5 and diversion box 6 will also move back and forth with the transmission block 10, so that the feed pellets can fall evenly into the net box. This allows the seedlings to finish the feed within a certain time, avoids the feed from deteriorating in the water, and improves the survival rate of the seedlings.

[0048] As the feeding mechanism controls the diversion box 6 to move back and forth, the first extrusion block 17 in the vibration mechanism also moves synchronously. When the arc-shaped part of the first extrusion block 17 contacts the sloping part of the second extrusion block 18, the first extrusion block 17 will drive the transmission rod 16, the linkage block 14 and the striking rod 15 to move upward due to the extrusion. When the first extrusion block 17 moves to a point where it no longer contacts the second extrusion block 18, the tension generated by the tension spring 19 will drive the linkage block 14 and the striking rod 15 to suddenly return to their original position downward. The striking rod 15 will strike the support plate 13 to generate vibration. The vibration force will be transmitted from the support plate 13 to the diversion box 6. The vibration will improve the flowability of the feed particles when they fall and prevent blockage.

[0049] It should be noted that the motor 8, controller 11, timer 12 and solenoid valve are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Furthermore, the specific composition and principle of the power supply of the motor 8, controller 11, timer 12 and solenoid valve are clear to those skilled in the art, and therefore will not be described in detail.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
