Description

Technical Field

[0001] This utility model relates to the field of vaccine sustained release, and in particular to a vaccine sustained release device for fish. Background Technology

[0002] With increasing emphasis on food safety, my country is continuously raising its technical requirements for disease prevention in aquaculture fish. Injection and vaccination of fish is an effective means of disease prevention.

[0003] Some existing fish vaccination devices work by mixing the vaccine into the feed in a liquid state and then releasing it into the fishpond, thereby vaccinating the fish while they are feeding.

[0004] However, the mixture of liquid vaccine and feed, after being stirred, is released into the fishpond in the form of a large volume of water, which is easily diluted by the water in the fishpond. This makes it difficult to create local conditions with a high concentration of vaccine in the fishpond. If the fish are directly placed into the tank containing the medicine for a bath, the process is very troublesome and can harm the fish, making it impossible to use on a large scale. Therefore, we have proposed a fish vaccine slow-release device to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that some existing fish vaccine devices release a mixture of vaccine and feed into fishponds in the form of a large body of water, which fails to create localized conditions with high vaccine concentrations in the fishponds, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a fish vaccine slow-release device, which solves the problem that some existing fish vaccine devices cannot create a localized high concentration of vaccine in the fishpond when releasing the vaccine.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a frame, a material bucket rotatably connected to one side of the frame, a driving unit above the material bucket, a first delayed feeding unit below the material bucket, and a second delayed feeding unit below the first delayed feeding unit;

[0009] The drive unit includes a motor, and a residual gear is fixedly connected to the drive end of the motor.

[0010] The first delayed feeding unit includes a rotating shaft rotatably connected inside the material barrel. One end of the rotating shaft is fixedly connected to a transmission gear. Two sets of feeding pipes are symmetrically fixedly connected to the bottom of the material barrel. The feeding pipes are connected to the inside of the material barrel. A guide rod is rotatably connected to the side wall of the feeding pipe. A baffle is fixedly connected to one end of the guide rod. A crossbeam is fixedly connected to the side wall of the frame. A disc is fixedly connected to one end of the crossbeam. A sleeve is fixedly connected above the disc. A delayed turntable is fixedly connected to one side of the sleeve.

[0011] In a preferred embodiment of the fish vaccine slow-release device of this utility model, the sleeve and the delay turntable both pass through the rotating shaft, a wedge-shaped surface is provided below one side of the delay turntable, and the delay turntable is located above one end of the guide rod and fits together with each other.

[0012] In a preferred embodiment of the fish vaccine slow-release device of this utility model, the second delayed feeding unit includes a first annular disk fixedly connected above the disc, and a second feeding hole is provided around the top of the first annular disk.

[0013] In a preferred embodiment of the fish vaccine slow-release device of this utility model, a second annular disk is rotatably connected above the first annular disk, a first feeding hole is arranged around the upper part of the second annular disk, and three teeth are fixedly connected to the side wall of the second annular disk.

[0014] In a preferred embodiment of the fish vaccine sustained-release device of this utility model, the second annular disk is located below the feed pipe, and the inner circle side of the second annular disk is provided with an annular wedge-shaped surface.

[0015] In a preferred embodiment of the fish vaccine sustained-release device of this utility model, an L-shaped bracket is fixedly connected to the side wall of the feeding pipe, and a rack is fixedly connected to one end of the L-shaped bracket.

[0016] As a preferred embodiment of the fish vaccine slow-release device of this utility model, the drive unit further includes a motor frame fixedly connected to one end of the frame, the motor is fixedly connected to the motor frame, and a feeding hopper is provided above the feed barrel.

[0017] In a preferred embodiment of the fish vaccine sustained-release device of this utility model, an annular groove is provided at the lower end of the feeding pipe, and an annular plate is fixedly connected to one side of the baffle.

The residual gear is connected to a first delayed feeding unit, which includes a delayed turntable and a feeding pipe located below the feed hopper. A guide rod is rotatably connected to one end of the feeding pipe, and a baffle is fixedly connected to one end of the guide rod. The guide rod is located below the delayed turntable. The feed hopper is driven to rotate by the residual gear, which in turn drives the feeding pipe, baffle, and guide rod to rotate. When the guide rod rotates to the wedge-shaped surface of the delayed turntable, the baffle flips downward, and the mixture of vaccine and feed in the feed hopper falls into the fishpond. By continuously and slowly releasing the vaccine and feed in this area, the fish concentrate in this area to eat the feed for a long time, thus achieving the effect of medicating the fish.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 4 This utility model provides a fish vaccine slow-release device, which includes a frame 100, one end of which is fixedly connected to the bank of a fishpond. A feed hopper 200 is rotatably connected to one side of the frame 100. The feed hopper 200 is designed to be rotatably connected for slow feeding. A drive unit 500 is provided above the feed hopper 200 for driving the feed hopper 200 to rotate and feed. A first delayed feeding unit 300 is provided below the feed hopper 200 for delayed release of the vaccine and feed mixture. A second delayed feeding unit 400 is provided below the first delayed feeding unit 300 for further delayed release of the vaccine and feed mixture released by the first delayed feeding unit 300, and evenly released to the fishpond area below the second delayed feeding unit 400. A feeding hopper 201 is also provided above the feed hopper 200 for feeding the stirred vaccine and feed mixture into the feed hopper 200.

[0033] The drive unit 500 includes a motor 502, and a residual gear 503 is fixedly connected to the drive end of the motor 502 for delaying the rotation of the material bucket 200 and cooperating with delayed feeding. The drive unit 500 also includes a motor frame 501 fixedly connected to one end of the frame 100, and the motor 502 is fixedly connected to the motor frame 501.

[0034] The first delayed feeding unit 300 includes a rotating shaft 302 rotatably connected inside the feed hopper 200. One end of the rotating shaft 302 is fixedly connected to a transmission gear 301. Two sets of feeding pipes 305 are symmetrically fixedly connected to the bottom of the feed hopper 200. The feeding pipes 305 are connected to the inside of the feed hopper 200. The mixture of vaccine and feed falls through the feeding pipes 305. A guide rod 3071 is rotatably connected to the side wall of the feeding pipe 305. One end of the guide rod 3071 is fixedly connected to a baffle 307. When the guide rod 3071 rotates, one end of it is used to cooperate with the wedge-shaped surface of the delayed turntable 303 to realize the feeding of the feeding pipe 305.

[0035] A crossbeam 101 is fixedly connected to the side wall of the frame 100. A disc 406 is fixedly connected to one end of the crossbeam 101. The disc 406 fixes the first annular disc 404, the sleeve 304 and the delay turntable 303. It is used to cooperate with the delayed feeding action of the first delayed feeding unit 300 and the second delayed feeding unit 400. A sleeve 304 is fixedly connected to the top of the disc 406. A delay turntable 303 is fixedly connected to one side of the sleeve 304. An annular groove 306 is opened at the lower end of the feeding pipe 305. An annular plate is fixedly connected to one side of the baffle 307. When the baffle 307 is flipped and reset, the cooperation between the annular plate and the annular groove 306 can improve the sealing and prevent the leakage of the mixture of vaccine and feed. The sleeve 304 and the delay turntable 303 both pass through the rotating shaft 302, so that when the rotating shaft 302 rotates, the delay turntable 303 is in a stationary state.

[0036] A wedge-shaped surface is provided on the lower side of one side of the time-delay turntable 303. The time-delay turntable 303 is located above one end of the guide rod 3071 and they are in close contact. When the guide rod 3071 rotates around the time-delay turntable 303, when one end of the guide rod 3071 rotates to the position of the wedge-shaped surface of the time-delay turntable 303, the end of the guide rod 3071 that contacts the wedge-shaped surface of the time-delay turntable 303 will tilt upward. At this time, the guide rod 3071 deflects, causing the baffle 307 to deflect downward, thereby realizing material feeding. When the guide rod 3071 continues to rotate, one end of the guide rod 3071 begins to move away from the wedge-shaped surface of the time-delay turntable 303. The guide rod 3071 begins to reset under the pressure of the time-delay turntable 303, causing the baffle 307 to deflect upward and reset, thereby stopping material feeding.

[0037] The second delayed feeding unit 400 includes a first annular disk 404 fixedly connected above the disk 406. A second feeding hole 405 is arranged around the top of the first annular disk 404. A second annular disk 401 is rotatably connected above the first annular disk 404, and a torsion spring is provided at the rotatable connection point to cooperate with the automatic reset of the second annular disk 401. The second annular disk 401 is used to receive the mixture of vaccine and feed falling from the feeding pipe 305. A first feeding hole 403 is arranged around the top of the second annular disk 401. The first feeding hole 403 and the second feeding hole 405 are designed to be staggered to facilitate the delayed feeding action of the second delayed feeding unit 400. Three teeth 402 are fixedly connected to the side wall of the second annular disk 401. The teeth 402 are perpendicular to the feeding pipe 305 in the plane. Two sets of teeth 402 are symmetrically arranged.

[0038] The second annular disc 401 is located below the feed pipe 305. The inner circle of the second annular disc is provided with an annular wedge-shaped surface. An L-shaped bracket 407 is fixedly connected to the side wall of the feed pipe 305. A rack 408 is fixedly connected to one end of the L-shaped bracket 407. When the rack 408 rotates with the feed pipe 305, the rack 408 meshes with the teeth 402 and drives the second annular disc 401 to rotate, so that the first feed hole 403 and the second feed hole 405 are interconnected. The mixture of vaccine and feed falls into the fishpond from the second feed hole 405. When the rack 408 no longer meshes with the teeth 402, the second annular disc 401 automatically resets under the action of the torsion spring at its rotation connection point. The first feed hole 403 and the second feed hole 405 are no longer interconnected, thus stopping the feeding.

[0039] In use, the vaccine and feed mixture is first added from the feed hopper 201 into the feed bin 200. Then, the motor 502 is started to rotate, which indirectly drives the transmission gear 301 to rotate. The transmission gear 301 drives the feed bin 200 to rotate via the rotating shaft 302. The feed bin 200 drives the feed pipe 305, baffle 307, and guide rod 3071 to rotate. When the guide rod 3071 rotates to the wedge-shaped surface of the delay turntable 303, the vaccine and feed mixture in the feed bin 200 falls from the feed pipe 305 to the first... On the second annular disc 401, after the feed pipe 305 continues to rotate a quarter turn, it meshes with the tooth 402 through the rack 408, which in turn drives the second annular disc 401 to rotate. This allows the vaccine and feed mixture, which is evenly dispersed on the second annular disc 401, to fall into the fishpond through the second feed hole 405. By repeatedly and slowly releasing the vaccine and feed mixture in the area below the first annular disc 404, the fish stay in the area for a long time and feed, thus effectively giving the fish a medicated bath.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
