Description

TECHNICAL FIELD

[0002] The prawn breeding feeding machine is a device used for feeding during prawn breeding, which can improve the uniformity of feeding and reduce the labor intensity through the use of the prawn breeding feeding machine.

[0003] Before feeding, many breeders add EM bacteria to the feed. EM bacteria can decompose organic matter such as prawn excrement, leftover feed and other biological carcasses in water, convert them into inorganic matter, reduce the accumulation of organic matter in water, and reduce the chemical oxygen demand and biological oxygen demand of water; by decomposing nitrogen-containing organic matter, it can reduce the accumulation of harmful substances such as ammonia nitrogen and nitrite, and also utilize hydrogen sulfide, organic acid, ammonia and amino acid in water, and has a denitrification effect to eliminate ammonium nitrite in water, so as to keep the water fresh and provide a good living environment for prawns.

[0004] The feed with EM bacteria added will produce water vapor when stored in the storage box due to the influence of water vapor or humid air, resulting in clumping of the feed.

[0005] In the prior art, for example, Chinese Patent No. CN216452707U discloses a feeding device for prawn breeding, which comprises a base, a feed bin, a plurality of supports, a hopper, a plurality of suspension balls, a stirring device and an auxiliary discharge device.

The side end of the feed bin is provided with the stirring device.

[0006] However, the above-mentioned device can only perform feeding and simple stirring functions, and cannot crush the clumped feed. The clumped feed will change its original shape and texture, and the particles may become too large, too hard or stick together, which makes it difficult for prawns to eat and chew, affects the feeding enthusiasm of prawns, and leads to a decrease in feeding amount. The feeding organs of prawns are relatively small, and the clumped feed is not conducive to the prawns to grab and hold with appendages, which increases the difficulty of prawn feeding and makes prawns consume more energy during feeding. Even some weak prawns may not be able to obtain enough food. SUMMARY

[0045] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0046] Please refer to Figures 1 to 14 In the embodiments of the present application, a prawn breeding feeding machine with EM bacteria decomposition function comprises a horizontal track structure 1 erected above a pond, and a walking trolley 2 is installed on the horizontal track structure 1; a feed storage tank 3 for storing feed is installed on the walking trolley 2; a screw feeder 4 is arranged on one side of the feed storage tank 3; the screw feeder 4 is connected with a feed feeding mechanism 5 at the end thereof; the feed feeding mechanism 5 comprises a front cover 6 and a rear cover 7, and a screening cylinder 8 is installed in the rear cover 7; a block breaking assembly 9 is installed in the screening cylinder 8;

[0047] A turning assembly 10 is arranged between the front cover 6 and the screening cylinder 8, and the turning assembly 10 is fixedly connected with the block breaking assembly 9;

[0048] An auger roller 12 is arranged at the axial position of the screening cylinder 8, and the auger roller 12 penetrates through the rear cover 7 and is located in a feed conveying shell 13; the shaft end of the auger roller 12 penetrates to the outer end of the feed conveying shell 13 and is connected with a motor for transmission; the feed conveying shell 13 is fixedly welded with the rear cover 7. A fixing seat is welded at the lower end of the rear cover 7, and the fixing seat is connected with the side wall of the feed storage tank 3 and is fixed by bolts or welding; the rear cover 7 is integrally provided with a feeding pipe at the lower end thereof.

[0049] Through the above technical solution, the feed mixed with EM bacteria is stored in the feed storage tank 3 and is conveyed to the front cover 6 by the screw feeder 4; after the feed falls, the turning assembly 10 rotates counterclockwise, and the feed is scraped into the screening cylinder 8 by a scraper; at this time, the block breaking assembly 9 also rotates, which can crush the hardened feed while pushing the feed that cannot be crushed into the auger roller 12, and then the feed is returned to the feed storage tank 3 by the auger roller 12, so as to form a circulating feeding of the feed, which is beneficial to repeated crushing of the hardened feed.

[0050] The granular feed passes through the screening cylinder 8 and falls into the front cover 6 and the rear cover 7 again, and is discharged through the feeding pipe at the bottom of the rear cover 7, so as to realize the feeding of the feed.

[0051] Crushing the compacted feed before feeding it to shrimp can increase their feed intake and digestibility, thus preventing more feed from remaining in the water. This avoids the decomposition and fermentation of leftover feed in the water, which would consume large amounts of dissolved oxygen, and also prevents the shrimp's living environment from being affected by oxygen deficiency in the water.

[0052] Please see the appendix Figures 11-14 In this embodiment, the screening cylinder 8 includes a cylinder shell 81, and a shaft cylinder 83 is located at the axial center of the cylinder shell 81. The shaft cylinder 83 is rotatably connected to the protruding ring on the inner side of the rear cover 7 through a slip ring. An opening groove 84 is provided on the upper surface of the shaft cylinder 83 to facilitate the entry of the caking material block.

[0053] The outer surface of the cylindrical shell 81 is provided with several discharge holes to facilitate the passage of feed; an inlet 82 is provided on one side of the cylindrical shell 81; a transition bridge 11 is fixed on the inner side of the inlet 82.

[0054] The material breaking assembly 9 includes a feeding cylinder 91, which is rotatably connected to the shaft cylinder 83. Multiple feeding plates 92 are evenly distributed in a ring around the outer side of the feeding cylinder 91, and each feeding plate 92 has a material breaking component 93 on one side. A rectangular groove 94 is formed below the side of the feeding plate 92 away from the material breaking component 93. The material turning assembly 10 has multiple scrapers, each scraper being L-shaped. The outer ends of the scrapers are in close contact with the outer wall of the screening cylinder 8 and the inner wall of the feed front cover 6.

[0055] By adopting the above technical solution, when the turning component 10 rotates, it will push the feed to the feed inlet 82, and then the feed will enter the inside of the cylinder shell 81 through the feed inlet 82. The rotating feed-pushing cylinder 91 will drive the push plate 92 and the crushing component 93 to rotate. The crushing component 93 will squeeze and crush the clumps of feed. Then, when the push plate 92 pushes the feed, the granular feed will fall into the rear cover 7 through the hole on the cylinder shell 81.

[0056] Unbroken material blocks are pushed upward by the pusher plate 92. As the pusher plate 92 continues to push, when the rectangular groove 94 and the open groove 84 overlap, the blocky feed falls into the shaft cylinder 83 and is then transported to the storage tank 3 by the auger roller 12.

[0057] In this embodiment, the transition cable tray 11 is arranged in an "n" shape, wherein the width of the transition cable tray 11 is less than the width of the feed inlet 82, and the height of the transition cable tray 11 is greater than the height of the feed inlet 82.

[0058] By adopting the above technical solution, the transition bridge 11 can serve as a transition bridge for the pressure roller 934, ensuring that the pressure roller 934 smoothly passes through the feed inlet 82.

[0059] In this embodiment, a square neck 95 is provided at the middle position of the outer end face of the feeding cylinder 91. A square neck hole is opened on the inner side of the square neck 95, and it is engaged with the end of the auger roller 12 away from the motor for transmission.

[0060] The flipping component 10 has a square neck hole at one end that fits into the square neck 95, and is inserted into the square neck 95 and then locked in place with screws.

[0061] By adopting the above technical solution, when the auger roller 12 rotates, it can drive the material feeding cylinder 91 to rotate. With the cooperation of the square neck 95, it can also drive the rotation of the material turning component 10, so that the material block is pushed into the cylinder shell 81, and the uncrushed material block can be returned under the pressure of the material block.

[0062] In this embodiment, the material crushing component 93 includes a telescopic cylinder 931, which has two cylindrical cavities, each of which is equipped with a spring 932; a telescopic rod 933 is also slidably connected in the cylindrical cavity, and the ends of the two telescopic rods 933 are movably connected to a pressure roller 934 through a fisheye joint.

[0063] By adopting the above technical solution, under the push of the spring 932, the telescopic rod 933 carries the front pressure roller 934 to crush the clump of material. When the pressure roller 934 passes the turning assembly 10, due to the change in position, the telescopic rod 933 compresses the spring 932 inward, so that the pressure roller 934 can pass smoothly through the feed inlet 82.

[0064] In this embodiment, the material conveying housing 13 is provided with a material pipe at the lower end near the motor, and the lower end of the material pipe extends into the storage tank 3.

[0065] The working principle of this invention is briefly described as follows: Feed mixed with EM bacteria (the feed can use EM bacteria from existing technologies, and this invention does not limit it) is stored in the storage tank 3 and conveyed to the feed front cover 6 by the screw feeder 4. As the feed falls, the turning component 10 rotates counterclockwise and scrapes the feed into the screening cylinder 8 using a scraper. At this time, the breaking component 9 is also rotating, which can crush the clumped feed while pushing the uncrushed feed into the auger roller 12. Then, the auger roller 12 is used to return the feed to the storage tank 3, thereby forming a circulating feed, which is beneficial for the repeated crushing of clumped feed.

[0066] The granular feed falls back into the feed front cover 6 and rear cover 7 through the screening cylinder 8, and is discharged through the feeding pipe at the bottom of the rear cover 7, thus realizing the feeding of feed.

[0067] Crushing the compacted feed before feeding it to shrimp can increase their feed intake and digestibility, thus preventing more feed from remaining in the water. This avoids the decomposition and fermentation of leftover feed in the water, which would consume large amounts of dissolved oxygen, and also prevents the shrimp's living environment from being affected by oxygen deficiency in the water.

[0068] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0069] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and 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.
