Description

Technical Field

[0001] This utility model relates to the field of shrimp farming technology, and more specifically, to a timed feeding device for micro-bait specifically for shrimp larvae. Background Technology

[0002] In the process of shrimp larvae farming, feeding is a key factor affecting the survival rate and growth rate of shrimp larvae. Because shrimp larvae are small in size, have limited food intake, and feed in a concentrated range, special micro-feeds are required.

[0003] However, some feeding devices are in fixed locations, which can easily lead to localized feed accumulation when feeding. This can result in some shrimp larvae not getting enough to eat, causing them to grow slowly. Furthermore, excessive feed in certain areas can pollute the water and potentially affect the shrimp larvae rearing results.

[0004] Therefore, a timed feeding device for micro-bait specifically for shrimp larvae is needed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a timed feeding device for micro-bait specifically for shrimp larvae, which has the advantages of spreading and uniformly distributing the bait.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a timed feeding device for micro-bait specifically for shrimp larvae, comprising a moving component, a hopper at the top of the moving component, a discharging component at the bottom of the hopper and at both the front and rear ends of the moving component, and supports at both the left and right ends of the moving component; the moving component includes a limiting block fixedly connected to the supports, a rack fixedly connected to the inner end of the limiting block, a guide rod fixedly connected to the limiting block below the rack, a sleeve block slidably connected to the middle of the guide rod, a shell fixedly connected to the top of the sleeve block and fitted onto the outside of the rack, a connecting block fixedly connected to the top of the shell, and the top of the connecting block fixedly connected to the hopper.

[0007] As a preferred embodiment of this utility model, a partition is fixedly connected inside the outer shell, and a first motor is fixedly connected to the bottom end of the partition. The transmission end of the first motor passes through the top end of the partition and is fixedly connected to a worm gear that is rotatably connected to the outer shell.

[0008] As a preferred embodiment of this utility model, a rotating shaft that is rotatably connected to the outer casing is provided on the left side of the worm, a worm wheel that meshes with the worm is fixedly connected to the middle of the rotating shaft, and a gear that meshes with a rack is fixedly connected to the middle of the rotating shaft and in front of the worm wheel.

[0009] As a preferred embodiment of this utility model, the discharge assembly includes a square tube fixedly installed at the bottom of the storage hopper, and the bottom end of the square tube is fixedly connected to a discharge cylinder.

[0010] As a preferred embodiment of this utility model, a second motor is fixedly connected to the left end of the discharge cylinder, and a transmission rod is fixedly connected to the transmission end of the second motor, the transmission rod passing through the discharge cylinder.

[0011] As a preferred embodiment of this utility model, a spiral blade is fixedly connected to the outer wall of the discharge cylinder, and the outer wall of the spiral blade is in contact with the inner wall of the discharge cylinder.

[0012] As a preferred embodiment of this utility model, the discharge cylinder is arranged horizontally.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the coordinated design of the moving component and the horizontal discharge cylinder, the feeding range is precisely expanded. In the moving component, the first motor drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the gear to rotate through the shaft. The gear and rack work together to move the outer shell, which in turn drives the storage hopper to move at a constant speed along the rack. With the horizontally set discharge cylinder, the feed pushed by the spiral blades can be spread horizontally with the movement of the storage hopper, so that shrimp larvae in different areas of the breeding pond can obtain feed evenly, reduce the growth differences caused by feeding competition, and significantly improve the overall survival rate and growth uniformity of shrimp larvae. 2. By precisely controlling the speed of the second motor, the rotation speed of the spiral blades can be adjusted synchronously. The faster the speed, the more feed the spiral blades push per unit time, and vice versa. The feed output can be flexibly set according to the feeding needs of shrimp larvae at different growth stages. In addition, the outer wall of the spiral blades is tightly attached to the inner wall of the feed cylinder, which can thoroughly scrape out the feed in the feed cylinder, avoiding feed residue and caking that would cause waste. This achieves multiple benefits such as precise feeding, cost saving, and water quality protection. Attached Figure Description

[0016] 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.

[0017] like Figures 1 to 6 As shown, this utility model provides a timed feeding device for micro-bait specifically for shrimp larvae, including a moving component 1. The top of the moving component 1 is provided with a storage hopper 3, and the bottom of the storage hopper 3 and both the front and rear ends of the moving component 1 are provided with a discharging component 2. The left and right ends of the moving component 1 are provided with a bracket 4. The moving component 1 includes a limiting block 101 fixedly connected to the bracket 4. The inner end of the limiting block 101 is fixedly connected with a rack 102. The bottom of the rack 102 is provided with a guide rod 103 fixedly connected to the limiting block 101. The middle part of the guide rod 103 is slidably connected with a sleeve block 106. The top of the sleeve block 106 is fixedly connected with a shell 104 fitted outside the rack 102. The top of the shell 104 is fixedly connected with a connecting block 105. The top of the connecting block 105 is fixedly connected to the storage hopper 3. The bracket 4 provides stable support for the entire device. The limiting block 101 fixes the position of the rack 102 and the guide rod 103, ensuring that they remain parallel and relatively stable. The sleeve block 106 can slide along the guide rod 103, providing guidance for the movement of the outer shell 104 and preventing the outer shell 104 from deviating during movement. The outer shell 104 is fitted onto the outside of the rack 102, which can protect the rack 102 from external impurities and can also move by cooperating with the rack 102 through the internal structure. Finally, the connecting block 105 drives the storage hopper 3 to move synchronously, laying the foundation for subsequent uniform feeding. The outer shell 104 has a partition 107 fixedly connected inside, and a first motor 108 is fixedly connected to the bottom end of the partition 107. The transmission end of the first motor 108 passes through the top end of the partition 107 and is fixedly connected to a worm gear 109 that is rotatably connected to the outer shell 104. The partition 107 divides the internal space of the housing 104, providing a stable installation position for the first motor 108 and preventing the first motor 108 from interfering with other transmission components. The first motor 108 serves as a power source, and its transmission end drives the worm gear 109 to rotate stably within the housing 104, converting electrical energy into mechanical energy to provide power support for the subsequent transmission process. Among them, a rotating shaft 110 is provided on the left side of the worm 109 and is rotatably connected to the housing 104. A worm wheel 111 that meshes with the worm 109 is fixedly connected to the middle of the rotating shaft 110. A gear 112 that meshes with the rack 102 is fixedly connected to the middle of the rotating shaft 110 and in front of the worm wheel 111. Through the meshing transmission of worm 109 and worm wheel 111, the rotational motion of worm 109 is converted into the rotational motion of worm wheel 111. The worm 109 and worm wheel 111 transmission has the effect of speed reduction and torque increase, which can reduce the speed and increase the torque, making the rotation of subsequent gear 112 more stable and powerful. Worm wheel 111 drives shaft 110 to rotate synchronously, which in turn causes gear 112 to rotate. Gear 112 meshes with rack 102, converting the rotational motion of gear 112 into the linear motion of outer shell 104 along rack 102, thereby realizing the movement of storage hopper 3 and ensuring that the feeding range covers the breeding area. Among them, the discharge component 2 includes a square tube 201 fixedly installed at the bottom of the storage hopper 3, and the bottom end of the square tube 201 is fixedly connected to the discharge cylinder 202. The storage hopper 3 and the discharge cylinder 202 are connected by a square tube 201, so that the micro-bait in the storage hopper 3 can smoothly pass through the square tube 201 and enter the discharge cylinder 202. The left end of the discharge cylinder 202 is fixedly connected to a second motor 203, and the transmission end of the second motor 203 is fixedly connected to a transmission rod 204, which passes through the discharge cylinder 202. Power is provided by the second motor 203, whose transmission end drives the transmission rod 204 to rotate inside the discharge cylinder 202. The design of the transmission rod 204 penetrating through the discharge cylinder 202 ensures that the transmission rod 204 remains stable during rotation, avoiding displacement or damage to the transmission rod 204 due to uneven force, and providing support for the stable operation of the subsequent spiral blade 205. Among them, the outer wall of the transmission rod 204 is fixedly connected with a spiral blade 205, and the outer wall of the spiral blade 205 is in contact with the inner wall of the discharge cylinder 202; The transmission rod 204 drives the spiral blades 205 to rotate inside the discharge cylinder 202. The design of the spiral blades 205 fitting snugly against the inner wall of the discharge cylinder 202 can fully scrape and push the feed in the discharge cylinder 202 forward, avoiding feed residue on the inner wall of the discharge cylinder 202 and causing waste. At the same time, by controlling the rotation speed of the spiral blades 205, the amount of feed discharged can be precisely controlled to meet the feeding needs of shrimp larvae at different growth stages. The discharge cylinder 202 is arranged horizontally; By setting the feed cylinder 202 horizontally, the direction in which the spiral blades 205 push the feed is matched with the direction in which the moving component 1 drives the storage hopper 3 to move, thereby expanding the feeding coverage area and ensuring that the shrimp larvae in the breeding area can eat evenly, avoiding local overfeeding or underfeeding, and improving the survival rate and growth quality of the shrimp larvae.

[0018] The working principle and usage process of this utility model are as follows: First, the entire device is placed in the designated area of ​​the shrimp larvae rearing pond. The support brackets 4 on both sides ensure the device is stable and fixed to prevent displacement due to vibration during feeding. Then, micro-bait suitable for shrimp larvae is added to the feeding hopper 3. The bait falls naturally through the inclined structure of the feeding hopper 3 and is initially collected in the discharge cylinder 202 of the discharge assembly 2 through the square tube 201 at the bottom. Then, the first motor 108 and the second motor 203 are turned on. The transmission end of the first motor 108 drives the worm gear 10. 9 rotates stably within the outer casing 104; since the worm 109 meshes with the worm wheel 111, the worm 109 can drive the worm wheel 111 to rotate, and the worm wheel 111 drives the coaxial rotating shaft 110 to rotate synchronously, thereby causing the gear 112 on the rotating shaft 110 to rotate accordingly; the gear 112 meshes with the rack 102, converting the rotational motion into the linear motion of the outer casing 104. At this time, the sleeve block 106 at the bottom of the outer casing 104 slides synchronously along the guide rod 103, providing guidance and limiting for the movement of the outer casing 104 and preventing deviation; the outer casing 104 is connected by the connecting block 1 at the top. 05 drives the storage hopper 3 to move at a constant speed along the length of the rack 102, achieving lateral coverage of the feeding range. The second motor 203 drives the transmission rod 204, which passes through the discharge cylinder 202, to rotate. The spiral blades 205 on the outer wall of the transmission rod 204 rotate together. Since the outer wall of the spiral blades 205 is in close contact with the inner wall of the discharge cylinder 202, it can fully scrape the micro-bait accumulated in the discharge cylinder 202 and push it forward through the spiral angle of the spiral blades 205, finally falling evenly from the end of the discharge cylinder 202 into the breeding pond. During this process... The preset speed of the second motor 203 remains stable, ensuring a constant output per unit time. This prevents the micro-bait from clogging the discharge cylinder 202 due to accumulation, and also prevents excessive output from polluting the water or insufficient output from affecting the shrimp larvae's feeding. When the storage hopper 3 moves to the preset end point of the travel with the moving component 1, the first motor 108 can be controlled to reverse. The first motor 108 drives the worm gear 109 to rotate in the opposite direction. Through the reverse transmission of the worm wheel 111, the rotating shaft 110, and the gear 112, the outer shell 104 drives the storage hopper 3 to return to the initial position along the rack 102.
