Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and in particular to a feed throwing device for fish farming. Background Technology

[0002] In traditional aquaculture, fish mainly rely on food sources in the natural environment, such as plankton, aquatic plants, and small aquatic animals in ponds. However, with the gradual expansion of aquaculture scale and the increasing demands for fish yield and quality, relying solely on natural food can no longer meet the needs of fish growth. As a result, feed feeding devices have emerged.

[0003] Traditional feeding devices are mostly fixed, with a single feeding location and difficulty in adjusting the direction and feeding distance. This causes fish to crowd together to compete for food, and when fish gather together, larger fish are more likely to eat smaller fish, thus demonstrating the poor practicality of existing feeding devices.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a feed throwing device for fish farming to solve the aforementioned technical defects.

[0023] 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.

[0024] Please see Figure 1 - Figure 5 As shown, this utility model is a feed throwing device for fish farming, including a base 1. The base 1 has a rotating groove 11 inside. A first stepper motor 12 is fixedly installed on the top of the base 1 by bolts. The drive shaft of the first stepper motor 12 passes through the base 1 and extends into the rotating groove 11, where a spur gear 13 is fixedly installed. A turntable 14 is rotatably connected inside the rotating groove 11. An external gear ring 15 is fixedly connected to the outside of the turntable 14. The external gear ring 15 meshes with the spur gear 13. When the first stepper motor 12 starts, it drives the spur gear 13 to rotate, which in turn drives the external gear ring 15 to rotate, and the external gear ring 15 drives the turntable 14 to rotate.

[0025] Above the turntable 14, there is also an array of first support rods 16. Above the first support rods 16, there is a feed box 17 fixedly connected. The bottom of the first support rods 16 is fixed to the turntable 14 by bolts. The inside of the feed box 17 is used to hold fish feed. A top plate 18 is fixedly installed on the top of the feed box 17 by bolts. One end of the top plate 18 has a slot. Inside the slot, there is a sliding cover 19 that is slidably connected. A handle 20 is fixedly welded on the top of the sliding cover 19. The opening and closing of the feed box 17 can be controlled by sliding the sliding cover 19 by the handle 20.

[0026] Below the feed bin 17, there is a fixedly connected conveying cylinder 21. The conveying cylinder 21 is connected to the interior of the feed bin 17. One end of the conveying cylinder 21 is fixedly connected to a rotating drum 22 by bolts. An integrally formed guide shell 23 is fixedly connected to the outside of the rotating drum 22. The guide shell 23 is connected to the interior of the rotating drum 22. An extension plate is also fixedly connected to the outside of the rotating drum 22. A second support rod is fixedly connected below the extension plate. An inclined feeding pipe 25 is also provided below one end of the conveying cylinder 21. The feeding pipe 25 is connected to the interior of both the conveying cylinder 21 and the rotating drum 22. An observation cover 24 is fixedly installed on one side of the rotating drum 22 by bolts. The observation cover 24 is made of transparent acrylic material. The feeding situation inside the rotating drum 22 can be observed through the observation cover 24.

[0027] One end of the conveyor cylinder 21 is also fixed with a second stepper motor 26 by bolts. The drive shaft of the second stepper motor 26 is inserted into the conveyor cylinder 21 and fixed with a connecting shaft 27. A spiral conveyor belt 28 is fixed to the outside of the connecting shaft 27 by welding. The other end of the connecting shaft 27 is also fixedly connected with an installation cylinder 29. The installation cylinder 29 is located inside the rotating drum 22 and is rotatably connected to the rotating drum 22. An axially distributed arc-shaped plate 30 is provided on the outside of the installation cylinder 29. One end of each arc-shaped plate 30 is fixedly connected to the installation cylinder 29.

[0028] When the second stepper motor 26 starts, it drives the connecting shaft 27 and the spiral conveyor belt 28 to rotate. When the spiral conveyor belt 28 rotates, it conveys the feed in the feed box 17 to the feed pipe 25 until the feed falls into the drum 22 through the feed pipe 25. At this time, the connecting shaft 27 drives the mounting cylinder 29 and its outer arc plate 30 to rotate, thereby throwing the feed in the drum 22 out through the guide shell 23. The feed feed rate and the feed throwing distance can be adjusted by adjusting the speed of the second stepper motor 26.

[0029] The working process and principle of this utility model are as follows:

[0030] In use, first push the sliding cover 19 at the handle 20 to open the feed box 17, then add feed into the feed box 17, and then close the sliding cover 19 at the handle 20 to prevent foreign objects from entering the feed box 17. At this time, start the first stepper motor 12 and the second stepper motor 26. The first stepper motor 12 starts and drives the spur gear 13 to rotate. The spur gear 13 drives the outer gear ring 15 and the turntable 14 inside it to rotate, thereby adjusting the direction of feed scattering.

[0031] When the second stepper motor 26 starts, it drives the connecting shaft 27 and the spiral conveyor belt 28 to rotate. When the spiral conveyor belt 28 rotates, it conveys the feed in the feed box 17 to the feed pipe 25 until the feed falls into the drum 22 through the feed pipe 25. At this time, the connecting shaft 27 drives the mounting cylinder 29 and its outer arc plate 30 to rotate, thereby throwing the feed in the drum 22 out through the guide shell 23. By adjusting the speed of the second stepper motor 26, the feed feed amount and the feed throwing distance can be adjusted, thereby realizing the multi-angle adjustable distance feeding operation of the feed.
