Description

Technical Field

[0001] The invention relates to the field of aquaculture equipment production, in particular to an automatic feeding device for aquaculture. Background Art

[0002] With the growth of the global population and the increasing demand for aquatic products, the aquaculture industry has developed rapidly. However, traditional artificial feeding methods face many challenges and limitations. Artificial feeding requires a lot of manpower and time, especially in large-scale farming. This not only increases farming costs, but may also lead to untimely and inaccurate feeding due to human factors, affecting the growth and health of aquatic products. For example, in some large-scale snakehead fish farms, due to the rapid growth rate of snakehead fish and the large fluctuations in their feed demand, traditional artificial feeding cannot meet their precise nutritional needs. To solve these problems, it is necessary to design an automatic feeding device for aquaculture. The automatic feeding device can adjust the feeding amount and time in real time according to the growth stage of the snakehead fish and the water quality, greatly improving the survival rate and yield of the snakehead fish.

[0003] There are certain defects in the existing automatic feeding devices used in aquaculture: in the process of large-scale production of sharp pond snakehead seedlings, in order to meet the breeding needs, many seedlings need to be distributed in multiple barrels as breeding places. The existing automatic feeding devices mostly use the rotation of the screw rod to push the feed forward and discharge it from the discharge port. For example, the Chinese patent announcement number is CN The invention patent 111903588B is titled as a feeding method for aquaculture, which includes: providing an automatic feeding device for aquaculture, the automatic feeding device for aquaculture includes a storage box, and the technical solution is to rotate the conveying screw and convey the bait falling into the conveying pipe to the upper end of the discharge pipe, and the bait then falls out of the discharge pipe and passes through the pipe body and the second funnel into the centrifugal throwing plate. However, since the feed particle size of the sharp pond snakehead seedlings is too small, when the screw rotates and pushes the feed, a certain gap inevitably exists between it and the cylinder wall, which becomes a space for small-particle feed to easily fall into. These small-particle feeds trapped in the gap are retained for a long time and are very likely to remain and breed bacteria in a humid environment. Later, when the automatic feeding is carried out, the feed particles are gradually absorbed by the feed particles. When the device is operated again, the bred bacteria may be put into the drum together with the feed, and then spread to the seedlings, causing various diseases and posing a serious threat to the health and growth of the seedlings. Secondly, this technical solution also realizes quantitative feeding by setting up a quantitative feeding mechanism. The motor drives the centrifugal throwing disc to rotate and throw out the bait, and throws out a quantitative bait within a certain period of time. However, since the multiple impeller blades in the centrifugal throwing disc are curved, during the rotation of the centrifugal throwing disc, the feed is easily retained in the gap between the impeller blades and the guide groove, which will cause the actual amount of feed thrown out to be less than the expected quantity, affecting the accuracy of quantitative feeding, and failing to meet the nutritional needs of the sharp pond snakehead seedlings, which may affect their growth and development.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] like Figures 1-4 As shown, an automatic feeding device for aquaculture includes a base 1, a breeding bucket 11 for placing fish fry is installed on the top of the base 1, a control instrument 12 is installed on the front side of the breeding bucket 11, and a water purification system 13 is installed on the top right side of the base 1. The water purification system 13 includes three-stage filtration, which can gradually remove large particles of impurities, suspended matter and some organic matter in the water, effectively reduce turbidity in the water, and improve the transparency of the water quality. At the same time, a sedimentation box and an ultraviolet disinfection box are also provided. The sedimentation box allows heavier particulate matter in the water to naturally settle to the bottom of the water under the action of gravity, further reducing the solid particle content in the water. The ultraviolet disinfection box can kill bacteria, viruses and other microorganisms in the water, reducing the risk of infection of snakehead fish. The control instrument 12 and the water purification system 13 are connected by a pipeline. A connecting seat 14 is installed on the top of the water purification system 13, and an alarm 15 is installed at the front end of the connecting seat 14. When abnormal conditions such as lack of oxygen and water occur, an alarm will be issued. A sealing seal for placing feed is provided above the connecting seat 14. Storage 16, quantitative conveying assembly 2, which is arranged above the connecting seat 14, is used for quantitative delivery of feed, and the quantitative conveying assembly 2 includes a quantitative barrel 21 installed above the connecting seat 14, and the quantitative barrel 21 is arranged in an inclined manner. The sealed storage 16 is arranged above the quantitative barrel 21. The rear end of the quantitative barrel 21 is equipped with an electric push rod 22, and the output end of the electric push rod 22 is equipped with a push plate 23. The push plate 23 is close to the end of the quantitative barrel 21 and is equipped with a first push rod 24. One end of the first push rod 24 slides through the interior of the quantitative barrel 21 and is equipped with a round push rod. A push cylinder 25 is provided with a spray disc 26 on the side of the round push cylinder 25 facing away from the first push rod 24. A plurality of spray ports arranged in a circular array are installed on the spray disc 26. A circulation pipe 27 is installed at the right end of the water purification treatment system 13. A water pump for spraying filtered water in the circulation pipe 27 is also installed inside the water purification treatment system 13. The top end of the circulation pipe 27 is installed below the right end of the first push rod 24. One end of the circulation pipe 27 passes through the first push rod 24, the round push cylinder 25 and the inside of the spray disc 26 in sequence and is connected to the spray port.

[0040] It should be noted that when the feed falls from the sealed storage 16 into the inclined quantitative barrel 21, the electric push rod 22 is started, pushing the push plate 23 at the output end to move forward, and the push plate 23 then drives the first push rod 24, and the first push rod 24 pushes the round push cylinder 25 to move in the quantitative barrel 21. In the process of the circular push cylinder 25 pushing the feed in the metering barrel 21 forward, the water pump is started, and the circulating water is transported to the inside of the injection disc 26 through the circulation pipe 27 and sprayed out from the injection port. Since the metering barrel 21 is arranged in an inclined manner, the small-particle feed inside the metering barrel 21 can be completely discharged from the metering barrel 21 under the dual cooperation of gravity and water pressure. The present invention provides a quantitative conveying component 2, and the inclined metering barrel 21 can make the small-particle feed easier to slide under the action of gravity, and the water pressure of the circulating water further assists the discharge of the feed, ensuring smooth and accurate feeding. In actual operation, if the gravity is insufficient, the increase in water pressure can make up for it, and vice versa. The two work together to ensure the complete discharge of the feed, effectively avoid the breeding of bacteria by feed residues, ensure the hygiene of the feed, and reduce the possibility of disease transmission.

[0041] It is worth noting that by controlling the number of times the electric push rod 22 is extended and retracted, the moving distance of the push plate 23 can be accurately controlled, thereby achieving quantitative pushing of the feed in the quantitative barrel 21.

[0042] like Figure 4-Figure 5 As shown, the side of the injection disc 26 facing away from the circular push cylinder 25 is in a notch-shaped structure. The injection disc 26 is rotatably connected on the left side of the circular push cylinder 25. A positioning rod 211 is installed on the top of the injection disc 26. A driving groove 212 is provided on the inner top wall of the metering barrel 21. The driving groove 212 is a threaded structure. The positioning rod 211 is slidably connected inside the driving groove 212. A rotator connected to the circulation pipe 27 is installed inside the injection disc 26.

[0043] The injection disc 26 is provided with a notch-shaped structure, which helps to prevent the feed from contacting the injection port when entering the metering barrel, thereby preventing blockage. During the movement of the injection disc 26 inside the metering barrel, the positioning rod 211 on the injection disc 26 moves along the driving groove 212 of the threaded structure, thereby causing the injection disc 26 to rotate back and forth on the circular push cylinder 25, and the rotator also rotates synchronously, thereby changing the direction of the injection port, so that water can be further sprayed on the feed inside the metering barrel 21, preventing the feed from being retained inside the metering barrel 21, so as to improve the cleaning effect and ensure the cleanliness and hygiene of the metering barrel 21.

[0044] The injection ports located at the outermost layer are arranged along one side of the inner wall of the metering barrel 21 , and the remaining injection ports are aligned along the axis of the metering barrel 21 .

[0045] Since the outermost jet openings are arranged along one side of the inner wall of the metering barrel 21, the distance between the jet openings and the inner wall of the metering barrel 21 is the shortest, and the remaining jet openings are aligned along the axis of the metering barrel 21, and the positions between the jet openings and the feed are also the closest. When the jet disk 26 rotates, water can be evenly sprayed on the feed in the metering barrel 21, and the inner wall of the metering barrel 21 can also be flushed. The closer the distance, the higher the intensity of the spray, which can prevent the feed from accumulating in a certain part of the metering barrel 21 and reduce the possibility of feed residue.

[0046] like Figure 2-Figure 3 As shown, a sealing assembly 221 is provided between the sealing storage 16 and the metering barrel 21, and the sealing assembly 221 includes a sealing seat 222 installed below the sealing storage 16, and a slider 223 is connected to the oblique upper part of the metering barrel 21 through a slide rail, and a sealing plate 224 is installed on the side of the slider 223 close to the sealing storage 16, and the lower half of the sealing plate 224 slides through the inner side of the sealing seat 222, and a compression spring 225 is installed between the upper part of the slider 223 and the sealing seat 222, and an L-shaped drive block 226 is installed on the side of the slider 223 facing away from the sealing plate 224, and a slot 227 is provided on the top of the first push rod 24, and the horizontal end of the L-shaped drive block 226 slides through the inside of the slot 227.

[0047] It should be noted that when the quantitative conveying component 2 drives the round push cylinder 25 to push along the inside of the quantitative barrel 21, the spring potential energy of the compression spring 225 is released. At this time, the slider 223 and the sealing plate 224 slide along the inside of the sealing seat 222. When the sealing plate 224 slides in the direction close to the sealed storage 16, it will gradually cover the opening between the sealed storage 16 and the quantitative barrel 21, realizing a sealing effect to prevent feed leakage, and at the same time effectively improve the accuracy of feed quantitative measurement. When the quantitative conveying component 2 drives the round push cylinder 25 to reset, when the sealing plate 224 slides in the direction away from the sealed storage 16, the opening between the sealed storage 16 and the quantitative barrel 21 gradually opens, and the feed can fall smoothly into the quantitative barrel 21. The sealing component 221 of the present invention can effectively control the delivery of feed while ensuring sealing performance and reducing the risk of feed leakage and contamination.

[0048] like Figure 1 、 Figure 3 、 Figure 6 and Figure 7As shown, the feeding assembly 3 is arranged above the breeding barrel 11 and is used to transport the quantitative feed to the breeding barrel 11. The feeding assembly 3 includes a uniform plate 31 installed obliquely below the quantitative barrel 21. The uniform plate 31 is connected to the quantitative barrel 21. A conical cylinder 32 is installed below the uniform plate 31. The bottom of the conical cylinder 32 is provided with a conical groove 33 in an annular array. A conical seat 34 is installed in the middle of the conical cylinder 32. The middle of the conical seat 34 is rotatably connected to a drive rod 35. Cleaning plates 36 are installed at the left and right ends of the drive rod 35. The rotation of the cleaning plate 36 can prevent the feed from being smeared in the conical cylinder 3. 2 is blocked, and at the same time, the feed falls more evenly. The top of the uniform disk 31 is rotatably connected to the driving gear 37 fixedly connected to the top of the driving rod 35. The front end of the uniform disk 31 is connected to the first rack plate 38 through a slide rail. The right side of the first rack plate 38 is installed with an inclined passive plate 39. The front end of the push plate 23 is installed with an active rod 391, and the left end of the active rod 391 is installed with an inclined seat, which is tightly attached to the oblique upper part of the passive plate 39. A limit block 392 is installed on the right side of the uniform disk 31, and a return spring rod 393 slidably connected to the limit block 392 is installed on the left side of the passive plate 39.

[0049] It should be noted that the feed falls from the quantitative barrel 21 into the uniform disk 31, and then falls through the conical groove 33 in the annular array at the bottom of the conical cylinder 32. When the quantitative conveying component 2 moves, the push plate 23 drives the active rod 391 and the inclined seat connected thereto to move. Since the active rod 391 moves, the inclined seat can slide from the oblique upper part of the passive plate 39. At this time, the passive plate 39 moves toward the left along the slide rail on the uniform disk 31, and the reset spring rod 393 is compressed. At this time, the first rack plate 38 drives the driving gear 37 to rotate, and the driving gear 37 drives the driving rod 35 and the cleaning disk 36 to move along the uniform disk 31 and the conical cylinder. The conical cylinder 32 rotates internally so that the feed inside the conical cylinder 32 is discharged from the conical groove 33, preventing the feed from staying inside the conical cylinder 32. At the same time, the circulating water inside the conical cylinder 32 can promote the discharge of feed. The present invention provides a feeding component 3, and through the rotation of the cleaning disk 36 and the promotion of the circulating water, it can more effectively promote the discharge of feed from the conical groove 33, while reducing the retention and blockage of feed during the transportation process. Compared with the traditional method, the speed and smoothness of feed discharge are greatly improved, ensuring that the feed can be accurately discharged according to the predetermined quantity, avoiding the problem of insufficient actual feeding amount due to feed retention in the traditional method.

[0050] It is worth noting that rollers are installed on the inclined seat to reduce the friction between the inclined seat and the passive plate 39 and improve the movement stability of the inclined seat on the passive plate 39.

[0051] like Figures 6-10As shown, the feeding assembly 3 further comprises a waterproof bag 311 mounted at the bottom of the conical cylinder 32, a sleeve 312 is mounted at the bottom of the conical cylinder 32 in a hollow manner, a first fixing member 313 is mounted at the top of the sleeve 312, a first round rod 314 is mounted at the outer side of the first fixing member 313, a first rotating plate 315 is rotatably connected to the outer side of the first round rod 314, the outer side of the first rotating plate 315 is fixedly connected to the inner side of the waterproof bag 311, a lead screw 316 is fixedly connected to the driving rod 35 and mounted at the middle of the sleeve 312, limit grooves are formed at the front and rear ends of the sleeve 312, a reciprocating seat 317 is slidably connected to the limit grooves in a threaded manner below the lead screw 316, a second fixing member 318 is fixedly connected to the reciprocating seat 317 and slidably connected to the lower side of the sleeve 312, the first fixing member 313 and the second fixing member 318 each comprise a round seat and an array of inclined blocks arranged on the outer side of the round seat, the first fixing member 313 and the second fixing member 318 are symmetrically arranged on the sleeve 312, a second round rod 319 is mounted at the outer side of the second fixing member 318, a second rotating plate 3191 is rotatably connected to the outer side of the second round rod 319, and one end of the second rotating plate 3191 is connected to the middle of the first rotating plate 315 through a rotating shaft.

[0052] It should be noted that when the driving rod 35 rotates, the lead screw 316 also rotates with the driving rod 35, and since the lead screw 316 is threadedly connected to the reciprocating seat 317 and the reciprocating seat 317 slides in the limit groove of the sleeve 312, the rotation of the lead screw 316 is converted into the up-and-down reciprocating motion of the reciprocating seat 317, and the reciprocating seat 317 drives the first rotating plate 315 to reciprocate through the second fixing member 318, the second round rod 319 and the second rotating plate 3191, so that the waterproof bag 311 is constantly opened and closed, which has two effects: on the one hand, it speeds up the sliding speed of the feed from the surface of the waterproof bag 311, reduces the residence time of the feed in the conveying process, and thus supplies the feed to the juvenile Acanthophacetus as soon as possible to ensure its normal feeding; on the other hand, the constant opening and closing of the waterproof bag 311 can disrupt the path and rhythm of the falling feed, so that the falling feed is more dispersed, avoiding the situation that some areas have too much feed and some areas have too little feed.

[0053] As Figure 4 , Figure 6 and Figure 11As shown, a spray assembly 321 is provided on the uniform disk 31, and the spray assembly 321 includes two fixing frames 322 installed at the front end of the uniform disk 31, and a piston cylinder 323 is installed between the two fixing frames 322. The left end of the return spring rod 393 slides through the piston cylinder 323 and a piston plate is installed inside the piston cylinder 323. A hose 324 is installed at the left end of the piston cylinder 323. The bottom of the uniform disk 31 is rotatably connected to a turntable 325, and gear teeth are installed on one side of the front end of the turntable 325. A second rack plate 327 is installed obliquely below the passive plate 39, and the second rack plate 327 is meshed with the gear teeth of the turntable 325. The bottom of the turntable 325 is provided with an annular array of air injection slots 326.

[0054] When the first rack plate 38 moves to the left, the piston plate on the left side of the return spring rod 393 pushes the piston cylinder 323. The gas inside the piston cylinder 323 is transported to the inside of the rotary disk 325 through the hose 324 and ejected through the air ejection slot 326, thereby cleaning the residual feed on the outer wall of the conical cylinder 32. At the same time, the air outlet of the air ejection slot 326 is directed through the conical cylinder 32 onto the waterproof bag 311, further promoting the discharge of feed on the waterproof bag 311. The provision of the ejection assembly 321 in the present invention ensures the cleanliness of the outer wall of the conical cylinder 32 and reduces the impact of residual feed on the equipment. At the same time, by promoting the discharge of feed on the waterproof bag 311, the stability and uniformity of the feed supply can be improved.

[0055] like Figure 7 As shown, the top of the cleaning disk 36 has an arc-shaped structure, and a micro brush 361 is installed on the cleaning disk 36 near the inner wall of the conical cylinder 32, and the brush 361 is arranged in an inclined manner toward the inner wall of the conical cylinder 32.

[0056] The curved surface is smoother, and the feed can slide down the curved surface more easily under the action of gravity, which can better prevent the accumulation of feed. The micro brush 361 is arranged at an angle, which can prevent the feed from being retained on the micro brush 361 for a long time when the cleaning disk 36 rotates, and can effectively remove the feed adhered to the conical cylinder 32.

[0057] It is worth noting that the inner opening of the conical groove 33 is larger than its outer opening. The larger inner opening provides a larger entrance for feed to enter the conical groove 33, reducing the resistance of feed entering. The bottom inner wall of the conical groove 33 is arranged downward, which is conducive to the natural sliding of feed under the action of gravity, reducing the possibility of feed being blocked in the conical groove 33, and ensuring that the feed can be discharged smoothly.

[0058] The working principle of the present invention is as follows: the feed falls from the sealed storage 16 into the inclined quantitative barrel 21, the electric push rod 22 is started, and the push plate 23 at the output end is pushed forward, and the push plate 23 drives the first push rod 24, and the first push rod 24 pushes the round push cylinder 25 to move in the quantitative barrel 21. In the process of the round push cylinder 25 pushing the feed in the quantitative barrel 21 forward, the water pump in the water purification system 13 is started, and the circulating water is transported to the inside of the injection disc 26 through the circulation pipe 27 and sprayed out from the injection port. The arrangement of the dosing barrel 21 is inclined. The small-sized feed inside the dosing barrel 21 can be completely discharged from the dosing barrel 21 under the dual cooperation of gravity and water pressure. When the spray disc 26 moves, the positioning rod 211 on its top slides along the threaded driving groove 212, causing the spray disc 26 to reciprocate on the circular push cylinder 25, changing the direction of the spray port, evenly spraying the feed, preventing feed from being retained, and washing the inner wall of the dosing barrel 21. The feed falls from the dosing barrel 21 into the uniform disk 31, and then passes through the bottom of the conical cylinder 32 in an annular array. The tapered groove 33 of the row falls, and when the quantitative conveying assembly 2 moves, the push plate 23 drives the active rod 391 and the inclined seat to move. The inclined seat slides from the oblique upper part of the passive plate 39, causing the passive plate 39 to move to the left along the slide rail on the uniform disk 31, compressing the return spring rod 393, and the first rack plate 38 drives the driving gear 37 to rotate. The driving gear 37 drives the driving rod 35 and the cleaning disk 36 to rotate along the uniform disk 31 and the inside of the tapered cylinder 32, prompting the feed to be discharged from the tapered groove 33 and preventing the feed from staying inside the tapered cylinder 32. The circulating water can also promote the discharge of feed. When the driving rod 35 rotates, it drives the screw rod 316 to rotate. The screw rod 316 is threadedly connected to the reciprocating seat 317, and the reciprocating seat 317 slides in the limiting groove of the sleeve 312, causing the reciprocating seat 317 to reciprocate up and down. The reciprocating seat 317 drives the first rotating plate 315 to swing back and forth through the second fixing member 318, the second round rod 319 and the second rotating plate 3191, thereby continuously opening and closing the waterproof bag 311, accelerating the speed at which the feed slides off the surface of the waterproof bag 311, and making the feed more evenly dispersed.
