Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, and in particular to a timed feeding device for aquaculture. Background Technology
[0002] Aquaculture refers to agricultural production activities that involve controlling the aquatic environment by introducing seedlings, regulating water quality, feeding, and preventing and controlling diseases to cultivate and raise aquatic organisms such as fish, shrimp, crabs, shellfish, and algae on a large scale, ultimately harvesting the products. In aquaculture, in order to ensure that the feed enters the aquatic organisms during the period when digestive enzyme activity is at its highest, thereby improving the absorption rate of nutrients such as protein and fat, it is generally necessary to feed the aquatic organisms at regular intervals.
[0003] For example, a timed feeding device for aquaculture disclosed in patent number CN218736648U uses a timer and a propeller to agitate the water to attract fish to feed. At the same time, a feeding motor rotates to release the feed, which falls into the water through the feed outlet. However, the feed outlet of this feeding device is in a fixed position, and the feed is concentrated in a fixed area. Fish near the feeding point will crowd together to compete for the feed, which can easily lead to some fish growing slowly due to insufficient food intake. It may also cause fish to bite and collide with each other due to fierce competition for food, increasing the risk of fish injury and disease infection. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide a timed feeding device for aquaculture, which solves the problem of the small feeding range of existing timed feeding devices.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a timed feeding device for aquaculture, including a feed cylinder; The bottom end of the material cylinder is provided with a discharge pipe, and the bottom of the discharge pipe is connected to a feeding bin through a rotary joint. A feeding pipe is provided on one side of the feeding bin. A baffle is provided inside the discharge pipe, and a second drive motor for driving the baffle to rotate is fixed on one side of the discharge pipe. A swing mechanism is provided on one side of the feeding bin, and the swing mechanism includes a frame set at the bottom of the material cylinder. A turntable is set at the top of the frame through a bracket, and a sliding sleeve is set on the turntable through an eccentric shaft. A swing rod passes through the inside of the sliding sleeve. A swing shaft is provided on one side inside the bracket, and the top of the swing shaft is connected to the bottom of the feeding bin. Both ends of the swing rod are connected to the swing shaft through connectors.
[0006] Preferably, movable bases are provided on both sides of the material cylinder, and telescopic rods are sleeved inside the movable bases. The tops of the telescopic rods are connected to the material cylinder through connecting rods, and timers are provided on the telescopic rods.
[0007] Preferably, both ends of the bottom of the movable base are provided with wheels, and the outer side of the wheels is provided with rubber sleeves.
[0008] Preferably, the telescopic rod has evenly spaced screw holes, and one side of the movable base is connected to the screw holes by fasteners.
[0009] Preferably, the inside of the material cylinder is provided with a rotating shaft, and the rotating shaft is provided with spiral blades. The top of the material cylinder is provided with a cover, and a third drive motor is fixed in the center of the top of the cover. The output end of the third drive motor is connected to the rotating shaft.
[0010] Preferably, a first drive motor is fixed on the side of the frame away from the turntable, and the output end of the first drive motor is connected to the turntable via a roller.
[0011] Preferably, the feeding pipe is inclined and located on one side of the feeding bin, and the feeding pipe is connected to the feeding bin.
[0012] The advantages of the timed feeding device for aquaculture provided by this utility model are as follows: The aquaculture tank is equipped with a feed cylinder, discharge pipe, baffle, second drive motor, feeding bin, feeding pipe, and swing mechanism. The swing mechanism includes a frame, first drive motor, turntable, eccentric shaft, sliding sleeve, swing rod, connecting parts, swing shaft, and support. The feed cylinder is mounted above the aquaculture tank. During discharge, the second drive motor drives the baffle to rotate and open, allowing the feed in the feed cylinder to enter the feeding bin below and fall into the water through the feeding pipe on one side of the feeding bin. During this process, the first drive motor drives the turntable to rotate. An eccentric shaft is mounted on the turntable, and the sliding sleeve connected to the eccentric shaft is fitted onto the swing rod. When the eccentric shaft undergoes lateral displacement, the sliding sleeve is forcibly pushed. The lateral thrust is then transmitted to the swing rod, which is converted into a rotational torque. Under the action of the torque, the swing rod will rotate in one direction until the eccentric shaft reaches the limit position of the circumference. The eccentric shaft continues to rotate with the turntable. After passing the limit position, its lateral thrust on the sliding sleeve becomes reversed, driving the swing rod to rotate in the opposite direction. As the turntable continues to rotate at a constant speed, the swing rod, along with the swing shaft, achieves continuous back-and-forth swinging. Since the top of the swing shaft is connected to the feeding bin, the feeding tube on the feeding bin swings back and forth, which can evenly spread the bait to a larger area of water, allowing fish in different locations to feed in time and avoiding the problem of local accumulation.
[0013] A rotating shaft with spiral blades is installed inside the feed cylinder. A cover is installed on the top of the feed cylinder, and a third drive motor is fixed on the top of the cover. The output end of the third drive motor is connected to the rotating shaft, which drives the spiral blades to rotate. When the spiral blades rotate, they cause the feed in the upper and lower layers of the feed cylinder to tumble and mix, making the feed loose and preventing clumping, which is conducive to subsequent discharge. Telescopic rods are installed on both sides of the feed cylinder. Screw holes are evenly opened on the telescopic rods. Movable bases are installed on the outer bottom of the telescopic rods. The movable bases are connected to the screw holes by fasteners. By connecting the fasteners and screw holes of different heights, the extension length of the telescopic rods can be adjusted, thereby adjusting the height position of the feed cylinder. It can be adjusted according to the specifications of the breeding tank. 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] Please see Figure 1-5 The present invention provides a timed feeding device for aquaculture, comprising a feed cylinder 1; Please see Figure 1 and Figure 5 The bottom end of the material cylinder 1 is provided with a discharge pipe 8, and the bottom of the discharge pipe 8 is connected to the feeding bin 2 through a rotary joint 9. A feeding pipe 3 is provided on one side of the feeding bin 2. The feeding pipe 3 is inclined on one side of the feeding bin 2 and is connected to the feeding bin 2. Movable bases 5 are provided on both sides of the material cylinder 1, and telescopic rods 15 are sleeved inside the movable bases 5. The top of the telescopic rods 15 is connected to the material cylinder 1 through a connecting rod. A timer controller 6 is provided on the telescopic rods 15. Wheels 18 are provided at both ends of the bottom of the movable bases 5, and rubber sleeves are provided on the outside of the wheels 18. Screw holes 16 are evenly opened on the telescopic rods 15. One side of the movable bases 5 is connected to the screw holes 16 through fasteners 17. First, according to the specifications of the breeding trough and the needs of the breeding species, the staff adjusts the extension length of the telescopic rod 15 by matching the fasteners 17 on the movable base 5 with the screw holes 16 at different heights on the telescopic rod 15, thereby adjusting the height of the feed cylinder 1 to adapt the device to the current breeding scenario and avoid feed waste or uneven feeding due to improper height. In addition, the wheels 18 at both ends of the bottom of the movable base 5 make it easy for the staff to move the device according to the breeding needs, further improving the practicality and flexibility of the device. The outer side of the wheels 18 is equipped with rubber sleeves to reduce wear on the ground during movement. The feeding time and single feeding duration are preset by the timer controller 6, completing the preparation work before the device is started. Please see Figure 1 and Figure 4 The material cylinder 1 is equipped with a rotating shaft 13 inside, and a spiral blade 14 is provided on the rotating shaft 13. The top of the material cylinder 1 is equipped with a cover 7, and a third drive motor 12 is fixed in the center of the top of the cover 7. The output end of the third drive motor 12 is connected to the rotating shaft 13. A first drive motor 402 is fixed on the side of the frame 401 away from the turntable 403, and the output end of the first drive motor 402 is connected to the turntable 403 through a roller. The output of the third drive motor 12 drives the rotating shaft 13 inside the feed cylinder 1 to rotate. The spiral blades 14 on the rotating shaft 13 rotate accordingly. During the rotation, the spiral blades 14 will cause the upper and lower layers of bait in the feed cylinder 1 to tumble and mix, keeping the bait in a loose state and effectively preventing the bait from clumping. At the same time, the spiral blades 14 rotate close to the inner wall of the feed cylinder 1, which can scrape off the bait hanging on the cylinder wall, preventing the bait from becoming moldy and deteriorating, and ensuring smooth subsequent discharge. Please see Figure 2-3The discharge pipe 8 is equipped with a baffle 10 inside, and a second drive motor 11 for driving the baffle 10 to rotate is fixed on one side of the discharge pipe 8. A swing mechanism 4 is provided on one side of the feeding bin 2. The swing mechanism 4 includes a frame 401 set at the bottom of the material cylinder 1. A turntable 403 is set at the top of the frame 401 through a bracket 408. A first drive motor 402 is fixed on the side of the frame 401 away from the turntable 403. The output end of the first drive motor 402 is connected to the turntable 403 through a roller. A sliding sleeve 405 is set on the turntable 403 through an eccentric shaft 404. A swing rod 406 passes through the inside of the sliding sleeve 405. A swing shaft 407 is provided on one side inside the bracket 408, and the top end of the swing shaft 407 is connected to the bottom of the feeding bin 2. Both ends of the swing rod 406 are connected to the swing shaft 407 through the connector 409. When the preset feeding time arrives, the timer controller 6 triggers the second drive motor 11. After the second drive motor 11 starts, it drives the baffle 10 inside the discharge pipe 8 to rotate and open. The bait in the feed cylinder 1 enters the feeding bin 2 below through the rotary joint 9 at the bottom of the discharge pipe 8. The bait in the feeding bin 2 then flows to the feeding pipe 3, which is set at an incline on one side. During the process of bait entering the feeding bin 2, the timer controller 6 synchronously triggers the first drive motor 402 in the swing mechanism 4 to start. The output end of the first drive motor 402 drives the turntable 403 on the top support 408 of the frame 401 to rotate through the roller. When the turntable 403 rotates, it drives the eccentric shaft 404 on it to perform circular motion. The sliding sleeve 405 connected to the eccentric shaft 404 moves accordingly. Since the swing rod 406 passes through the inside of the sliding sleeve 405, and the two ends of the swing rod 406 are connected to the swing shaft 407 on one side of the support 408 through the connector 409, when the eccentric shaft 404 performs circular motion... When the movement generates lateral displacement, the sliding sleeve 405 is forcibly pushed and transmits the lateral thrust to the swing rod 406. The thrust is converted into the rotational torque of the swing rod 406. Under the action of the torque, the swing rod 406 drives the swing shaft 407 to rotate in one direction until the eccentric shaft 404 rotates to the limit position of the circumference. Then the eccentric shaft 404 continues to rotate with the turntable 403. After passing the limit position, its lateral thrust on the sliding sleeve 405 reverses, driving the swing rod 406 to drive the swing shaft 407 to rotate in the opposite direction. As the turntable 403 continues to rotate at a constant speed, the swing shaft 407 realizes continuous back-and-forth swing. Because the top of the swing shaft 407 is connected to the bottom of the feeding bin 2, the swing shaft 407 swings and drives the feeding bin 2 to swing synchronously. The feeding pipe 3 on one side of the feeding bin 2 swings back and forth, spreading the feed that falls into the water from the feeding pipe 3 evenly to a larger area of water, so that fish in different positions in the breeding tank can eat in time and avoid waste caused by local accumulation of feed.
