Abstract
Description
Technical Field
[0001] This application pertains to the field of aquaculture, and more specifically, relates to a feed distribution device for aquaculture, which is suitable for various fish species such as grass carp and black carp. Background Technology
[0002] In aquaculture, fish need to be fed using feeders. However, during the feeding process, feed can only be placed in the area near the feeder, making it difficult to achieve diffuse feeding.
[0003] To solve the above-mentioned technical problems, the prior art provides a fish fry breeding device, as disclosed in Chinese Patent Publication No. CN117084209A. It includes a shell and a feeding hopper fixed to the top of the shell. The top and bottom sides of the shell have inlets and outlets, and a column is fixed at the center of the bottom of the shell. Feed is added through the feeding hopper and fed at a constant speed and quantity by a feeding valve, allowing the feed to be spread evenly on the conveyor belt through the feeding nozzle. Driven by a second motor, the conveyor belt transports the feed from the inside to the outside. The inner guide plate blocks the feed on the left side of the conveyor belt, while the rear guide plates block the feed one by one at equal intervals, guiding it outwards along the slope of each guide plate to the feed trough. Under inertia, the feed is spread in segments on the feed distribution plate in the feed trough and falls through the through-holes on the distribution plate for feeding.
[0004] However, the aforementioned existing technologies require the use of conveying mechanisms to increase the feeding range, but they cannot achieve the diffusion of feed as the feeding range increases; at the same time, their spreading mechanisms can only spread the feed downwards, but cannot increase the spreading speed, and cannot achieve the feed supply speed for fish such as grass carp and silver carp that prefer to live in the middle and bottom of the water layer. Summary of the Invention

[0025] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.
[0026] Example 1
[0027] like Figures 1 to 7 As shown, a feed distribution device for aquaculture includes a base 1 with a through hole for connection to a ship-mounted device. Vertical support frames 2 are symmetrically arranged on both sides of the base 1, each with reinforcing ribs. Adjacent vertical support frames 2 are connected by horizontal support frames 3. The vertical support frames 2 and the horizontal support frames 3 constitute a frame structure for the fixed connection of the feed distribution tray 10.
[0028] The fabric tray 10 is inclined relative to the base 1. Specifically, the outlet of the fabric tray 10 is lower than the inlet of the fabric tray 10. A mixing outlet pipe 9 is provided in the direction of the inlet of the fabric tray 10. The mixing outlet pipe 9 is located above the fabric tray 10, and its top end is connected to the mixing cylinder 8. The connection between the mixing outlet pipe 9 and the mixing cylinder 8 is located in the middle of the mixing cylinder 8.
[0029] A mixing shaft 17 is coaxially arranged inside the mixing cylinder 8. Screwdriver blades 18 are symmetrically arranged inside the mixing shaft 17, with the mixing shaft 17 as a reference for the screwdriver blades 18. The screwdriver blades 18 are symmetrically arranged on the mixing shaft 17 with respect to the central symmetry plane of the mixing cylinder 8. The screwdriver blades 18 can synchronously feed the feed fed into the middle of the mixing cylinder 8 through the mixing inlet pipe 7, and after mixing with the feed fed into the middle of the mixing cylinder 8, the feed is fed into the distribution plate 10 through the mixing outlet pipe 9.
[0030] The mixing shaft 17 extends from both ends of the mixing cylinder 8 and is fixedly connected to a mixing driven wheel 11. The mixing driven wheel 11 is connected to the mixing drive wheel 22 via a transmission device. The mixing drive wheel 22 is located at both ends of the mixing drive shaft 23, and both ends of the mixing drive shaft 23 are connected to the vertical support frame 2 via a bearing structure. The mixing drive shaft 23 is driven by a mixing driver 24 on the base 1, which is located at one end of the base 1. Several discharge cylinders 4 are distributed at the other end of the base 1 corresponding to the mixing driver 24. The discharge cylinders 4 are connected to the mixing cylinder 8 via a cylinder outlet pipe 5, a negative pressure suction device 6, and a mixing inlet pipe 7.
[0031] Example 2
[0032] See also Figures 1 to 7 As shown, based on Example 1, a feed distribution device for aquaculture is provided, and for details please refer to... Figure 6 The fabric tray 10 has folded edge structures on both sides and top, and a fabric cover 13 is fixedly connected to the top of the fabric tray 10, forming a fabric chamber between the fabric tray 10 and the fabric cover 13. The fabric tray 10 and the fabric cover 13 form a horn structure at the top of the fabric chamber, and a mixing outlet pipe 9 is connected to the inlet of the horn structure.
[0033] Several fabric guide blocks 16 are distributed at the outlet of the horn structure, forming several fabric channels between adjacent fabric guide blocks 16. Several fabric nozzles 15 are connected to the fabric cover 13 corresponding to the fabric channels. The fabric nozzles 15 are collected on the purge gas collection pipe 14, which is located above the fabric disc 10 and is connected to the high-pressure gas generator 19 through the pipe body. The bottom end of the high-pressure gas generator 19 is also connected to the bottom end of the discharge cylinder 4 through the cylindrical purge pipe 20. The bottom end of the discharge cylinder 4 is circumferentially provided with a purge gas collection chamber 32 that is connected to the cylindrical purge pipe 20. The purge gas collection chamber 32 is surrounded by the cylindrical conical bottom 30 at the bottom end of the discharge cylinder 4. Several purge ports 31 are distributed on the cylindrical conical bottom 30. The purge ports 31 are connected to the purge gas collection chamber 32, and the outlet of the purge port 31 is smaller than the inlet. The bottom inlet of the cylindrical discharge pipe 5 is provided with a suction pipe cone 29, and the suction pipe cone 29 has several rectangular notches distributed around its circumference. The bottom inlet of the cylindrical discharge pipe 5 is located above the bottom end formed by the conical bottom 30 of the cylindrical body.
[0034] Based on the above embodiments, this application will be further described and illustrated to help those skilled in the art fully understand the technical solutions described in this application and be able to reproduce them.
[0035] The feed cylinder 4 described in this application is multiple and fixedly connected to the base 1. Each feed cylinder 4 is provided with a feed inlet 21. The inlet of the feed inlet 21 is connected to a cover through a sealing gasket and a threaded structure. Different feed pellets are put into the feed cylinder 4 through the feed inlet 21.
[0036] The discharge cylinder 4 has an internal discharge pipe 5 extending to its bottom. The bottom end of the discharge pipe 5 is open and has a conical suction nozzle 29. The suction nozzle 29 has several rectangular notches distributed around its circumference to facilitate rapid feed delivery. The top end of the discharge pipe 5 is connected to a negative pressure suction device 6 via a flange structure. The negative pressure suction device 6 uses a negative pressure generating device to draw the feed from the discharge cylinder 4 into the mixing inlet pipe 7, and then into the mixing cylinder 8. In this structure, after the feed is delivered into the mixing cylinder 8 by the negative pressure suction device 6 and the mixing inlet pipe 7, it is evenly distributed within the mixing cylinder 8. The feed is then fed and collected by the mixing shaft 17 and the auger blades 18 within the mixing cylinder 8.
[0037] The bottom end of the feeding cylinder 4 forms a conical bottom surface through the conical bottom 30 of the cylinder body. The conical inlet 29 of the suction pipe is located above the conical bottom surface, and a sufficient gap for feed to be fed is formed between the conical inlet 29 and the conical bottom surface. Several purge ports 31 are distributed circumferentially on the conical bottom 30 of the cylinder body. The cross-section of the purge ports 31 is shown in [reference needed]. Figure 4 In the structure shown, the outlet inner diameter of the purge port 31 is smaller than the inlet inner diameter of the purge port 31. The conical bottom 30 of the cylinder forms a purge gas collecting chamber 32 at the bottom end of the discharge cylinder 4, distributed around the discharge pipe 5. The purge gas collecting chamber 32 is connected to the cylinder purge pipe 20. The cylinder purge pipe 20 collects gas and connects to the high-pressure gas generator 19 through a shut-off valve. The high-pressure gas generator 19 is fixedly connected to the base 1 by a bracket. This structure can stably achieve material extraction from the cylinder discharge pipe 5, avoiding the problem of feed accumulation at the bottom of the discharge cylinder 4, which would prevent material extraction.
[0038] A one-way valve is installed at the top cover of the discharge cylinder 4, which allows external gas to be supplied into the discharge cylinder 4. Several one-way valves are installed along the length of the mixing cylinder 8, which allow gas inside the mixing cylinder 8 to be discharged to the outside of the mixing cylinder 8.
[0039] Vertical support frames 2 are provided on both sides of the base 1, and a horizontal support frame 3 is connected between adjacent vertical support frames 2. A fabric tray 10 is fixedly installed on the horizontal support frame 3, and the fabric tray 10 and the fabric cover 13 form a fabric chamber.
[0040] The fabric cover 13 and the fabric tray 10 are provided with a number of fabric guide blocks 16 in the outlet direction. A number of fabric channels are left between adjacent fabric guide blocks 16. A number of fabric nozzles 15 are connected to the fabric cover 13 above the fabric channels. The fabric nozzles 15 are used to realize the fabric speed and range of the feed at the outlet.
[0041] The area above the feeding channel formed by the feeding guide block 16 is equipped with several feeding rollers 12. Each feeding roller 12 includes a primary feeding auger 25, a secondary feeding auger 26, and a tertiary feeding auger 27. Several spiral blades are symmetrically arranged on each of the primary, secondary, and tertiary feeding augers 25 and 26, respectively. These symmetrically arranged spiral blades enable feeding from inside the trumpet-shaped structure to the outside of the feeding disc 10. The terminal dispersing rod 28 is located between the tertiary feeding auger 27 and the feeding channel to achieve uniform feed distribution. Several rubber rods are distributed along the axis and axial direction of the terminal dispersing rod 28, which distribute the feed accordingly.
[0042] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
