Description

Technical Field

[0001] This utility model relates to the field of feed conveying technology, specifically a feed mixing device. Background Technology

[0002] As aquaculture develops towards large-scale and intensive operations, the efficiency and precision of feed delivery have become key concerns for the industry. Currently, pre-formed block or pellet feed is commonly used in aquaculture, and its transportation and storage largely rely on standardized packaging. In actual feeding, different species of aquatic animals have significantly different requirements regarding whether or not their feed is mixed with medication: some species require direct feeding of whole pellets, while others require the feed to be mixed with medication before feeding to suit their growth and digestive characteristics.

[0003] However, large-scale fish farms generally use centralized feed distribution systems, where the same conveying device needs to supply feed to multiple aquaculture units. In existing technologies, feed distribution systems mostly focus on a single function, only supporting mixed feed or only supporting direct feeding in small pieces, lacking adaptability to differentiated feeding needs. Utility Model Content

[0004] Therefore, in order to solve the above problems, the purpose of this utility model is to provide a feed mixing device, including a mixing chamber, a mixing drive motor is provided below the mixing chamber, the output end of the mixing drive motor is connected to a mixing spiral blade and extends into the mixing chamber, the lower side of the mixing chamber is connected to a pre-storage chamber through a feeding channel, the lower end of the pre-storage chamber is connected to a shut-off valve, the output end of the shut-off valve is connected to the feed conveying channel, a feeding motor is provided on the side of the feeding channel, the output end of the feeding motor is connected to a feeding gate and extends into the feeding channel, the feeding gate is used to control the opening and closing of the feeding channel.

[0005] Preferably, both the mixing chamber and the pre-storage chamber are equipped with flip-top covers.

[0006] Preferably, both the mixing chamber and the pre-storage chamber are equipped with a discharge gate device at their top. The discharge gate device includes a discharge channel and a discharge motor. The output end of the discharge motor is connected to the discharge gate and extends into the discharge channel. The discharge channel is connected to the mixing chamber or the pre-storage chamber.

[0007] Preferably, the mixing chamber is installed at a higher height than the pre-storage chamber, and the material conveying channel is inclined downwards at an angle of 50°.

[0008] Preferably, the upper end of the side wall of the pre-storage compartment is provided with a guide groove, and a stirring rod mounting seat is movably connected to the guide groove. The stirring rod mounting seat is provided with a claw, and a stirring rod is engaged in the claw.

[0009] Preferably, the guide groove includes a working section and a stationary section. When the stirring rod mounting seat slides to the working section of the guide groove, the stirring rod extends into the pre-storage chamber. When the stirring rod mounting seat slides to the stationary section of the guide groove, the stirring rod is located outside the pre-storage chamber.

[0010] Preferably, the claw is conical, and the diameter of the opening at the end of the claw facing the pre-storage compartment is larger than the diameter of the opening at the end facing away from the pre-storage compartment.

[0011] The beneficial effects of this utility model are:

[0012] This feed mixing device effectively resolves the conflict between differentiated feeding needs and a shared conveying system in large-scale fish farms through its integrated design. The device employs a dual-compartment layout with a mixing chamber and a pre-storage chamber, equipped with an independent mixing drive system and a conveying control mechanism. When feeding mixed feed with medicated liquid, the material is efficiently mixed in the mixing chamber by the mixing spiral blades, and then temporarily stored in the pre-storage chamber via the conveying channel. When feeding unmixed pelleted feed directly, the material bypasses the mixing process and enters the pre-storage chamber directly. Both operating modes ultimately achieve stable feed output through a unified airlock device, avoiding cross-contamination and residue issues of different feed forms in the shared conveying channel. This significantly improves equipment utilization and feeding accuracy, reduces energy consumption and cleaning costs, and ensures the integrity and nutritional consistency of feed forms required by various aquatic animals, demonstrating high engineering practicality and promotional value.

[0026] Example 1:

[0027] Figures 1-7This invention provides a feed mixing device, including a mixing chamber 1 and a pre-storage chamber 2. A mixing drive motor 11 is provided below the mixing drive motor 11. The output end of the mixing drive motor 11 is connected to a mixing spiral blade 12 and extends into the mixing chamber 1. The mixing drive motor 11 can drive the mixing spiral blade 12 to rotate and mix and break up small pieces of feed in the mixing chamber 1. The lower side of the mixing chamber 1 is welded and connected to a conveying channel 4. The other end of the conveying channel 4 is also connected by welding. A conveying motor 41 is provided on the side of the conveying channel 4. The output end of the conveying motor 41 is connected to a conveying gate 42 and extends into the conveying channel 4. The conveying gate 42 is used to control the opening and closing of the conveying channel 4. The lower end of the pre-storage bin 2 is connected to the air shut-off device 3. The output end of the air shut-off device 3 is connected to the feed delivery channel. The air shut-off device 3 is a common device that can deliver materials in a timed and quantitative manner. It includes an impeller 31 and a motor that drives the impeller 31 to rotate. It is also equipped with a corresponding closed pipe. The feed accumulated in the pre-storage bin 2 can be output to the feed delivery channel in a timed and quantitative manner as the impeller 31 rotates evenly.

[0028] It should be noted that the output end of the stirring drive motor 11 is wrapped with a belt, and the other end of the belt is wrapped around the rotating shaft of the stirring spiral blade 12. Therefore, the stirring drive motor 11 drives the stirring spiral blade 12 to rotate via the belt.

[0029] Both the mixing chamber 1 and the pre-storage chamber 2 are equipped with a discharge gate device 5 at their top. The discharge gate device 5 includes a discharge channel 51 and a discharge motor 52. The output end of the discharge motor 52 is connected to a discharge gate 53 and extends into the discharge channel 51. The discharge channel 51 is connected to the mixing chamber 1 or the pre-storage chamber 2. The discharge gate device 5 is used to centrally and uniformly transport the transported feed to the mixing chamber 1 or the pre-storage chamber 2. The discharge motor 52 controls the movement of the gate, thereby controlling the opening and closing of the discharge channel 51.

[0030] The mixing chamber 1 is installed at a higher height than the pre-storage chamber 2. The conveying channel 4 is inclined downward at an angle of 50° to facilitate the feed entering the pre-storage chamber 2 along the conveying channel 4.

[0031] Both the mixing chamber 1 and the pre-storage chamber 2 are equipped with flip-top covers 6, which facilitates the handling of malfunctions of the airlock 3 and the pre-storage chamber 2 by the staff. When the feed in the pre-storage chamber 2 clumps together, the flip-top covers 6 can also be opened to handle the clumping problem with the stirring rod 72.

[0032] The upper side wall of the pre-storage chamber 2 is provided with a guide groove 21, and a stirring rod mounting base 7 is movably connected to the guide groove 21. The stirring rod mounting base 7 is provided with a claw 71, and a stirring rod 72 is engaged in the claw 71. The guide groove 21 includes a working section and a stationary section. When the stirring rod mounting base 7 slides to the working section of the guide groove 21, the stirring rod 72 extends into the pre-storage chamber 2. When the stirring rod mounting base 7 slides to the stationary section of the guide groove 21, the stirring rod 72 is located outside the pre-storage chamber 2. It is cone-shaped, and the diameter of the opening of the end of the claw 71 facing the pre-storage bin 2 is larger than the diameter of the opening of the end away from the pre-storage bin 2. In this embodiment, the separately set stirring rod 72 is fixed to the upper edge of the pre-storage bin 2 by the stirring rod mounting base 7. When there is a problem of clumping and condensation in the pre-storage bin 2, the stirring rod mounting base 7 is rotated so that the end of the stirring rod 72 stuck on the claw 71 faces the inside of the pre-storage bin 2. The operator can insert the stirring rod 72 into the pre-storage bin 2 and swing and shake it to break up the clumped and condensed feed.

[0033] Working principle:

[0034] The transported feed is controlled by the top discharge gate device 5, allowing it to selectively enter either the pre-storage bin 2 or the mixing bin 1. When mixed feed is required, the feed is introduced into the mixing bin 1, and the mixing drive motor 11 drives the mixing spiral blade 12 to rotate, thoroughly mixing the feed and medicine in the bin. After mixing, the conveying motor 41 starts and opens the conveying gate 42, allowing the mixed feed to automatically flow into the pre-storage bin 2 for temporary storage due to gravity and the inclined guide of the conveying channel 4. If shaped block feed needs to be fed directly, the feed enters the pre-storage bin 2 directly through the discharge gate device 5, completely bypassing the mixing process. The feed in the pre-storage bin 2 is finally delivered in a timed, quantitative, uniform, and stable manner through the airlock device 3, and then sent to the designated feeding point through the delivery channel. In addition, the pre-storage bin 2 is equipped with a guide groove 21 and a stirring rod mounting base 7 on its side wall. If the feed in the bin clumps or condenses, the staff can slide the mounting base to the working section and insert the stirring rod 72 into the bin for manual assistance in dispersing the clumps. After processing, the feed can be returned to the static section for storage, thereby ensuring the continuity and reliability of the conveying process and effectively solving the problem of cross-contamination and residue of feeds of different forms in the shared system.

[0035] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
