Description

Technical Field

[0001] The utility model relates to the technical field of seafood feed processing, in particular to a feed crusher for seafood farming. Background Art

[0002] Seafood farming is to make economic animals and plants reproduce and grow through artificial control and management in a specific water body. According to the ecological habits of the farming objects, suitable environmental conditions are created to promote the massive reproduction and rapid growth of organisms. During the farming process, it is necessary to feed them to ensure their growth. The feed needs to be crushed before feeding. After the feed is crushed, it can ensure that organisms can eat normally.

[0003] A feed crushing device for seafood farming is disclosed in the related technology (publication number: CN215464953U). The disclosed technical solution: When the utility model is used, the motor is started, the motor drives the rotating shaft to rotate, and then drives the crushing blade to rotate. At the same time, the rotating shaft drives the upper pulley to rotate, the upper pulley drives the mounting shaft to rotate, and then drives the cam to rotate, and then drives the mounting column to rotate, and then drives the screening plate to vibrate. The large pieces of feed are added into the crushing box from the feed hopper. Under the crushing action of the crushing blade and the screening action of the screening plate, the feed meeting the feeding requirements is discharged from the discharge hopper, which is convenient for the staff to feed the marine animals. The large-particle feed remains on the screening plate, and the staff re-add the feed remaining on the screening plate into the feed hopper for crushing, so that the feed can be crushed thoroughly; When the utility model is used, it can screen the crushed feed to ensure that the feed can be crushed thoroughly, and the feeding effect is very good, reducing the feeding cost.

[0004] In the above-mentioned disclosed technical solution, it is found that the following problems exist in the related technology: During the process of crushing and processing the feed, due to large-scale processing, the feed may not be crushed thoroughly. Once the feed is not crushed thoroughly, the farmed organisms cannot eat it. The organisms cannot digest the feed with larger specifications after eating, thus affecting the growth of the organisms. Therefore, the feed must be crushed thoroughly before feeding. For this reason, we propose a new type of feed crusher for seafood farming.

[0005] It should be noted that the information disclosed in the above background art section is only used to strengthen the understanding of the background art section of the present application.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Next, in combination with specific implementation cases and attached Figures 1-6 The present utility model will be further described, but the present utility model is not limited to these embodiments.

[0031] Embodiment 1

[0032] A feed crusher for seafood farming, comprising a crushing box 1, and a crushing mechanism is arranged in the inner cavity of the crushing box 1. A feed hopper 16 is fixedly installed on the upper part of the crushing box 1 in a fitting manner, so that the feed hopper 16 is communicated with the crushing box 1. The upper feed port range is increased through the feed hopper 16 to prevent the raw materials from falling outside. A sieve plate 20 is arranged below the crushing mechanism, and a vibrating sieve assembly for driving the sieve plate 20 to vibrate is arranged at the bottom of the crushing box 1. Through the vibrating sieve assembly, the sieve plate 20 slides up and down in a fitting manner on the inner wall of the crushing box 1. Sieve holes are sequentially and evenly formed on the surface of the sieve plate 20, and the specification of the sieve plate 20 corresponds to that of the crushing box 1. The periphery of the sieve plate 20 is in sliding contact with the inner wall of the crushing box 1, and the crushed feed is screened by the vibrating sieve plate 20.

[0033] A feeding cylinder 3 for conveying the screened feed is arranged on one side of the crushing box 1, and a guiding channel is obliquely arranged between the feeding cylinder 3 and the crushing box 1. A connecting seat 11 is fixedly sleeved outside the feeding cylinder 3, and the connecting seat 11 is fixed on the surface of the crushing box 1 through a fixing rod. The position of the guiding channel corresponds to that of the sieve plate 20, and the guiding channel is located above the sieve plate 20, so that the inner cavity of the crushing box 1 is communicated with the inside of the feeding cylinder 3 through the inclined guiding channel. A conveying assembly for feeding materials into the crushing box 1 is arranged in the inner cavity of the feeding cylinder 3. After being screened by the sieve plate 20, the feed enters the inside of the feeding cylinder 3 through the guiding channel, and then the large-sized feed screened out is fed into the inside of the crushing box 1 again through the internal conveying assembly.

[0034] During the vibration screening process of the sieve plate 20, since the feed falls through between the two crushing rollers 2 after being processed by the two crushing rollers 2, there is very little feed on both sides of the sieve plate 20, and a very small part of the feed may enter the inside of the feeding cylinder 3 through the guiding channel. After being crushed again, a small part of the feed is crushed in a cycle, and its quantity proportion is very small, so it will not affect the overall efficiency. However, the sieve holes of the sieve plate 20 can ensure that most of the feed is screened. Since the influence is not significant, a corresponding baffle is not provided. During this process, a baffle can be slid into the guiding channel opening. Since the influence is not significant, it will not be elaborated here.

[0035] A scraper 21 for pushing feed into the material guiding channel is arranged on the sieve plate 20, and a pushing component for pushing the scraper 21 is arranged on one side of the crushing box 1 away from the feeding cylinder 3. After the feed is crushed, the pushing component is used to push the scraper 21, so that the bottom of the scraper 21 fits on the upper surface of the sieve plate 20 and slides, and the feed that is not completely crushed and screened out on the sieve plate 20 is pushed onto the material guiding channel. It enters the inside of the feeding cylinder 3 through the inclined material guiding channel, and then the recycled feed is transported to the top of the feeding cylinder 3 through the conveying component. The recycled feed enters the inside of the crushing box 1 again, so that the feed that is not completely crushed is crushed again, ensuring the effect of feed crushing, and further ensuring that aquatic organisms can feed on the feed.

[0036] Among them, the conveying component includes a movable shaft 24 rotatably arranged inside the feeding cylinder 3. Bearings are embedded and installed on the inner walls on the upper and lower sides of the feeding cylinder 3, and both ends of the movable shaft 24 are respectively embedded and installed inside the two bearings, so that the movable shaft 24 rotates inside the feeding cylinder 3. The outer wall of the movable shaft 24 is circumferentially provided with auger blades 29. The auger blades 29 are continuously and circumferentially fixedly sleeved on the outer wall of the movable shaft 24 in sequence, so that the movable shaft 24 drives the auger blades 29 to rotate continuously.

[0037] A feeding pipe 6 for feeding materials into the crushing box 1 is obliquely arranged on the outer wall of the feeding cylinder 3 near the top. One end of the feeding pipe 6 is fixedly embedded and installed on the outer wall of the feeding cylinder 3, and the feeding pipe 6 is located on the outer wall of the feeding cylinder 3 opposite to the crushing box 1, so that the feeding pipe 6 is communicated with the inside of the feeding cylinder 3. The other end of the feeding pipe 6 is obliquely directed towards the top of the feed hopper 16 and is located above the feed hopper 16. The feed conveyed by the auger blades 29 enters the inside of the feed hopper 16 through the feeding pipe 6. A first motor 10 is fixed on the top of the feeding cylinder 3 through a motor bracket, and the first motor 10 is electrically connected to an external power supply through a wire. The output shaft of the first motor 10 penetrates the top of the feeding cylinder 3 and is fixedly connected to the corresponding end of the movable shaft 24.

[0038] After the feed is scraped off from the sieve plate 20 and enters the inside of the feeding cylinder 3 through the material guiding channel, the first motor 10 is connected to the power supply, so that the output shaft of the first motor 10 drives the movable shaft 24 to rotate. The movable shaft 24 drives the auger blades 29 to rotate continuously, conveys the recycled feed to the feeding pipe 6, and enters the inside of the feed hopper 16 through the feeding pipe 6, so as to crush the screened feed again.

[0039] It should be noted that the material guiding channel includes a material guiding bin 12 which is inclinedly arranged on the side wall of the crushing box 1. The outer wall near the bottom of the feeding cylinder 3 is inclinedly embedded and installed with a material guiding pipe 5, and the material guiding pipe 5 is communicated with the material guiding bin 12. One side of the material guiding bin 12 is fixedly embedded and installed on the side wall of the crushing box 1 opposite to the feeding cylinder 3, and the other side of the material guiding bin 12 is fixedly connected with one end of the material guiding pipe 5. The other end of the material guiding pipe 5 is fixedly embedded and installed on the outer wall of the feeding cylinder 3. The feed is introduced into the interior of the feeding cylinder 3 through the inclined material guiding bin 12 and the material guiding pipe 5, ensuring the stability of the feed recycling process.

[0040] In addition, the pushing component includes an electric push rod 15 fixedly installed on the side wall of the crushing box 1, and the electric push rod 15 is located on the side far from the feeding cylinder 3. The movable end of the electric push rod 15 is fixedly installed on the side wall of the scraper 21, and the movable end of the electric push rod 15 penetrates through the side wall of the crushing box 1 and extends into the inner cavity. The electric push rod 15 is fixed on the surface of the crushing box 1 through a fixing frame, and the electric push rod 15 is in a position perpendicular to the surface of the crushing box 1. The electric push rod 15 is electrically connected to an external power supply through a wire. The movable rod of the electric push rod 15 slides in the through hole on the side wall of the crushing box 1, and the movable end of the electric push rod 15 is vertically fixed on the surface of the scraper 21.

[0041] When the feed screened out on the sieve plate 20 is subjected to re-crushing treatment, the movable end of the electric push rod 15 drives the scraper 21 to slide on the surface of the sieve plate 20, and the feed is pushed into the interior of the material guiding bin 12 through the contacting scraper 21, thus ensuring more thorough crushing treatment of the feed.

[0042] In addition, an extension plate 22 is embedded at the bottom of the scraper 21. A cavity is opened at the bottom of the scraper 21, and the width of the cavity corresponds to that of the extension plate 22, so that the extension plate 22 slides and is embedded into the cavity, and the extension plate 22 slides in contact with the inner wall of the cavity. The extension plate 22 and the scraper 21 form a telescopic plate member. An elastic component is arranged between the top of the extension plate 22 and the top of the inner wall of the scraper 21. The arranged elastic component ensures the degree of fit between the extension plate 22 and the surface of the sieve plate 20, thus ensuring more thorough scraping of the feed.

[0043] Further, the elastic component includes a first elastic member 27 disposed between the top of the extension plate 22 and the top inner wall of the scraping plate 21. The first elastic member 27 can be a compression spring. One end of the first elastic member 27 is fixed to the top inner wall of the scraping plate 21, and the other end of the first elastic member 27 is fixed to the top of the extension plate 22. One end of a sliding rod 26 is fixedly installed on the top inner wall of the scraping plate 21. The other end of the sliding rod 26 penetrates through the top of the extension plate 22 and extends into the inner cavity, and the first elastic member 27 is sleeved outside the sliding rod 26. A slot hole corresponding to the sliding rod 26 is formed in the upper surface of the extension plate 22, so that the bottom of the sliding rod 26 is embedded in the slot hole. The sliding rod 26 fits and slides on the inner wall of the slot hole, and the first elastic member 27 fits and slides telescopically on the outer wall of the sliding rod 26. The sliding rod 26 ensures the stability of the moving direction of the extension plate 22, avoiding position deviation, thereby ensuring more thorough feed treatment on the surface of the sieve plate 20.

[0044] The vibrating sieve assembly includes a movable rod 7 penetrating through the bottom of the crushing box 1. One end of the movable rod 7 is fixedly installed at the bottom of the sieve plate 20. The other end of the movable rod 7 is fixedly installed with a movable plate 23. A second elastic member 28 is sleeved on the outer wall of the movable rod 7, and the second elastic member 28 is disposed between the crushing box 1 and the movable plate 23. A cam 17 is rotatably provided at the bottom of the crushing box 1, and the cam 17 abuts against the bottom of the movable plate 23. The second elastic member 28 can be a compression spring. A discharge pipe 8 is fixedly installed at the bottom of the crushing box 1. A valve 9 is provided on the discharge pipe 8 to control the opening and closing of the discharge pipe 8. A second motor 19 is fixed to the surface of the discharge pipe 8 through a fixing bracket. The cam 17 is fixedly sleeved on the output shaft of the second motor 19 through a mounting hole formed on the surface. The second motor 19 is electrically connected to an external power supply through a wire.

[0045] The position where the second motor 19 is fixed ensures that the cam 17 abuts against the lower surface of the movable plate 23. One end of the second elastic member 28 is fixed to the bottom of the crushing box 1, and the other end of the second elastic member 28 is fixed to the upper surface of the movable plate 23. The second elastic member 28 fits and slides telescopically on the outer wall of the movable rod 7. The movable rod 17 passes through the bottom of the crushing box 1 and is vertically fixed to the bottom of the sieve plate 20, so that the movable rod 7 slides in the through hole at the bottom of the crushing box 1. The output shaft of the second motor 19 drives the cam 17 to rotate continuously, so that the movable rod 7 drives the sieve plate 20 to vibrate up and down, thereby screening the crushed feed.

[0046] The crushing mechanism includes a crushing roller 2 rotatably arranged in the inner cavity of the crushing box 1. Bearings are embedded and installed on the inner walls of the front and rear sides of the crushing box 1. The two ends of the central shafts of the two crushing rollers 2 are respectively embedded and installed inside the two bearings, and the two crushing rollers 2 are in a relatively meshing position. The central shafts of the two crushing rollers 2 penetrate through the side walls of the crushing box 1 and extend to the outside, and a gear 13 is fixedly sleeved on the outer surface of the central shaft of the crushing roller 2 outside the crushing box 1, and the two gears 13 on the central shafts of the two crushing rollers 2 are meshed with each other. The third motor 14 is fixed on the surface of the crushing box 1 through a motor bracket, and the third motor 14 is electrically connected to an external power supply through a wire.

[0047] The output shaft of the third motor 14 is fixedly connected to one end of the central shaft of the corresponding crushing roller 2. When processing the feed by crushing, the third motor 14 is connected to the power supply, so that the output shaft of the third motor 14 drives the central shaft of the corresponding crushing roller 2 to rotate. The two meshing gears 13 rotate relatively, so that the two crushing rollers 2 rotate relatively and meshingly, and the feed is crushed by the mutually meshing crushing rollers 2, thus ensuring the efficiency of the feed processing process.

[0048] The working principle of the feed crusher for seafood farming in this embodiment is as follows: First, the feed is put into the inside of the crushing box 1 from the feed hopper 16. Then the third motor 14 is connected to the power supply, so that the output shaft of the third motor 14 drives the central shaft of the corresponding crushing roller 2 to rotate, and the two meshing gears 13 rotate relatively. Thus, the two crushing rollers 2 rotate relatively and meshingly, and the feed is crushed by the mutually meshing crushing rollers 2.

[0049] Then, the output shaft of the second motor 19 drives the cam 17 to rotate continuously, so that the movable rod 7 drives the sieve plate 20 to vibrate up and down. The crushed feed falls through the sieve holes to the inside of the discharge pipe 8 and is discharged due to the vibration of the sieve plate 20. The screened feed remains on the surface of the sieve plate 20. Then, the movable end of the electric push rod 15 drives the scraper 21 to slide on the surface of the sieve plate 20, and the feed is pushed into the inside of the material guiding bin 12 by the fitting scraper 21.

[0050] Then the first motor 10 is connected to the power supply, so that the output shaft of the first motor 10 drives the movable shaft 24 to rotate. The movable shaft 24 drives the auger blade 29 to rotate continuously, and the recycled feed is conveyed to the material conveying pipe 6. It enters the inside of the feed hopper 16 through the material conveying pipe 6, so as to crush the screened feed again.
