Description

Technical Field

[0001] This utility model relates to the field of feeding devices, and in particular to a feeding device for graded feeding of aquatic feed organisms. Background Technology

[0002] Feed is the food used to feed aquatic animals in aquaculture. It is generally divided into natural feed and artificially made pellet feed. Common natural feeds include plankton, tubifex worms, snails, clams, small fish and shrimp, etc. They are nutritionally balanced and palatable, but have high acquisition costs and poor stability. Artificial pellet feed is made from fish meal, soybean meal, grains, additives, etc. in proportion. It allows for precise control of nutrition, is easy to store and feed, and is the mainstream choice for large-scale aquaculture.

[0003] In the existing technology, when feeding aquatic species using feeding devices, the feeding devices on the market usually do not have a grading effect, which causes the pellets to fall directly into the breeding pond. Because the pellets are large, small fish cannot eat them properly, resulting in larger fish eating more, causing an imbalance in feeding, which in turn affects the normal growth of the fry. Utility Model Content

[0004] The purpose of this invention is to provide a biological graded feeding device for aquatic feed, which can achieve the graded feeding effect of the feeding device, so that the smaller feed particles can be smoothly put into the pond for raising small fish, so that the small fish can eat smoothly, thereby ensuring the normal growth of the fish fry.

[0005] To achieve the above objectives, a biological graded feeding device for aquatic feed is provided, comprising an aquaculture pond, a support plate fixedly connected to the aquaculture pond, a protrusion slidably connected to the inner surface of the support plate, a toothed plate fixedly connected to the upper surface of the protrusion, a connecting block fixedly connected to the upper surface of the toothed plate, a hopper fixedly connected to the upper surface of the connecting block, a filter plate fixedly connected to the inner surface of the hopper, a first feeding plate and a second feeding plate fixedly connected to the hopper, a first electric push rod and a second electric push rod fixedly connected to the hopper, a first baffle fixedly connected to the output end of the first electric push rod, a second baffle fixedly connected to the output end of the second electric push rod, and a barrier plate fixedly connected to the inner surface of the aquaculture pond.

[0006] A support frame is fixedly connected to the upper surface of the support plate, a stepper motor is fixedly connected to the upper surface of the support frame, a connecting shaft is fixedly connected to the output end of the stepper motor, an incomplete gear is fixedly connected to the lower surface of the connecting shaft, a first limiting block is fixedly connected to the upper surface of the support plate, two guide rods are fixedly connected to the front surface of the first limiting block, the same slider is slidably connected to the two guide rods, the left surface of the slider is fixedly connected to the toothed plate, the same second limiting block is fixedly connected to the two guide rods, and springs are slidably sleeved on the outer surfaces of the two guide rods.

[0007] According to the aforementioned biological grading and feeding device for aquatic feed, a limiting groove is provided on the support plate, and the outer surface of the protrusion is slidably connected to the limiting groove.

[0008] According to the aforementioned biological grading and feeding device for aquatic feed, the lower surface of the first baffle is in contact with the first feeding plate, and the right surface of the first baffle is in contact with the hopper.

[0009] According to the aforementioned biological grading and feeding device for aquatic feed, the lower surface of the second baffle is in contact with the second feeding plate, and the left surface of the second baffle is in contact with the hopper.

[0010] According to the aforementioned biological grading and feeding device for aquatic feed, one end of the spring is fixedly connected to the rear surface of the second limiting block, and the end of the spring away from the second limiting block is fixedly connected to the front surface of the first limiting block.

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-6 This utility model discloses a biological graded feeding device for aquatic feed, comprising a culture pond 1, a support plate 2 fixedly connected to the culture pond 1, a protrusion 3 slidably connected to the inner surface of the support plate 2, a toothed plate 4 fixedly connected to the upper surface of the protrusion 3, a connecting block 5 fixedly connected to the upper surface of the toothed plate 4, a hopper 6 fixedly connected to the upper surface of the connecting block 5, a filter plate 7 fixedly connected to the inner surface of the hopper 6, a first feeding plate 8 and a second feeding plate 9 fixedly connected to the hopper 6, a first electric push rod 10 and a second electric push rod 12 fixedly connected to the hopper 6, a first baffle 11 fixedly connected to the output end of the first electric push rod 10, the lower surface of the first baffle 11 contacting the first feeding plate 8, and the right surface of the first baffle 11 contacting the hopper 6, and a second baffle 13 fixedly connected to the output end of the second electric push rod 12, the lower surface of the second baffle 13 contacting the second feeding plate 9, and the left surface of the second baffle 13 contacting the hopper 6. A baffle plate 14 is fixedly connected to the inner surface of the breeding pool 1. A limit groove 15 is opened on the bearing plate 2. The outer surface of the protrusion 3 is slidably connected to the limit groove 15. It should be noted that when the stepper motor 17 is turned off, the teeth on the incomplete gear 19 need to mesh with the teeth on the tooth plate 4. This is because when the stepper motor 17 is turned off, its output shaft will remain in the current position. This is because the stator winding of the stepper motor 17 will still generate a certain static holding torque when it is not energized, which can prevent the motor rotor from rotating arbitrarily due to external force, thereby achieving self-locking and preventing the tooth plate 4 and the structure on the tooth plate 4 from moving again, ensuring the stability of the hopper 6. In addition, the first electric push rod 10 and the second electric push rod 12 are both electric telescopic rods with self-locking function, such as worm gear electric telescopic rods, to ensure the stability of the positions of the first baffle 11 and the second baffle 13, and to prevent the first baffle 11 and the second baffle 13 from opening during the movement of the hopper 6.

[0028] A support frame 16 is fixedly connected to the upper surface of the support plate 2. A stepper motor 17 is fixedly connected to the upper surface of the support frame 16. A connecting shaft 18 is fixedly connected to the output end of the stepper motor 17. The connecting shaft 18 passes through the support frame 16. The outer surface of the connecting shaft 18 is rotatably connected to the support frame 16. An incomplete gear 19 is fixedly connected to the lower surface of the connecting shaft 18. The incomplete gear 19 meshes with the gear plate 4. A first limiting block 20 is fixedly connected to the upper surface of the support plate 2. Two guide rods 21 are fixedly connected to the front surface of the first limiting block 20. The same slider 22 is slidably connected to the two guide rods 21. The left surface of the slider 22 is fixedly connected to the gear plate 4. The same second limiting block 23 is fixedly connected to the two guide rods 21. Springs 24 are slidably sleeved on the outer surfaces of the two guide rods 21. One end of the spring 24 is fixedly connected to the rear surface of the second limiting block 23. The end of the spring 24 away from the second limiting block 23 is fixedly connected to the front surface of the first limiting block 20.

[0029] Working Principle: The baffle plate 14 in the aquaculture pond 1 divides the space into different aquaculture areas. Larger aquatic products can be placed in the area on the left side of the baffle plate 14, while smaller aquatic products can be placed in the area on the right side. When feeding pelleted feed, the pellets are first placed in the feed hopper 6. After adding the appropriate pellets, the smaller pellets pass through the filter plate 7 and onto the second feed plate 9, while the larger pellets remain on the filter plate 7. At this point, the stepper motor 17 on the support frame 16 is activated, causing the connecting shaft 18 and the incomplete gear 19 to rotate. This rotation of the incomplete gear 19 moves the meshing toothed plate 4. The moving toothed plate 4 then moves the connecting block 5, the feed hopper 6, and other structures on the feed hopper 6. This movement of the toothed plate 4 causes the slider 22 to move and compress the spring 24, keeping the spring 24 taut. When the partially rotating gear 19 is no longer engaged with the first limiting block 20, the spring 24 will rebound without being compressed, causing the rebounding spring 24 to drive the slider 22 to move back to its original position. The moving slider 22 can drive the toothed plate 4 and the structure on the toothed plate 4 to move back to its original position. As the partially rotating gear 19 continues to rotate, the toothed plate 4 can move back and forth, thereby increasing the fluidity of the bait on the filter plate 7 and improving the filtering effect of the bait. After moving back and forth for a period of time, the stepper motor 17 can be turned off. At this time, the bait is fully screened. Then, the first electric push rod 10 and the second electric push rod 12 are started respectively, so that the first baffle 11 and the second baffle 13 are moved upward respectively. At this time, the larger bait particles can be fed into the left breeding space through the first feeding plate 8, while the filtered bait will be fed into the right breeding space through the second feeding plate 9, realizing graded feeding.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
