An automatic feeding device and process for mixing and crushing raw materials of aquatic feed for grouper

Abstract

This invention discloses an automatic feeding device for mixing, crushing, and feeding grouper aquatic feed ingredients, relating to the field of grouper aquaculture technology. It includes a base, with a fixed shell fixedly installed on the top of the base, and a drive assembly fixedly installed on one side of the fixed shell. This invention achieves good feed crushing effect by incorporating a crushing ring, crushing roller, and elastic plates. During rotation, the four crushing plates contact one side of the elastic plates, and the rotation of the crushing plates pushes the bones inside the crushing ring, placing the bones between the elastic plates and the crushing plates. The rotation of the crushing plates compresses the bones between the elastic plates and the crushing plates, causing the bone fragments to break under pressure. Because the inner diameter of the crushing ring gradually decreases from left to right, the bones move from the left end to the right end of the elastic plates, gradually being crushed between the elastic plates and the crushing plates, thus achieving good feed crushing effect.

Description

Technical Field

[0001] This invention relates to the field of grouper aquaculture technology, specifically to an automatic feeding device and process for mixing, crushing and feeding grouper aquaculture feed ingredients. Background Technology

[0002] Grouper is a general term for fish in the subfamily Grouperidae. They are characterized by their rich nutrition and delicious flesh. Currently, grouper farming primarily relies on formulated feed. Therefore, the quality of this feed directly impacts the success of grouper farming. High-quality grouper feed not only has high feed utilization but also produces groupers with rapid growth, strong vitality, and high-quality flesh. The quality of formulated grouper feed depends mainly on two aspects: the formula and the production process.

[0003] Grouper feed is mostly composed of fish meal, chicken meal, meat and bone meal, fish fillet meal, soybean meal, peanut bran, and other raw materials. Currently, the preparation process for grouper feed requires crushing, mixing, and sieving these raw materials to obtain the final product. Since most soybean meal and peanut bran are produced by extruding soybeans and peanuts to extract oil, resulting in flakes, the grouper feed preparation process requires crushing these materials and passing them through a 50-80 mesh sieve to meet the feed preparation requirements. Fish fillet meal and meat and bone meal, due to their high content of fish and meat bones, still contain many small fish bones and meat scraps. Bone particles also need to be further pulverized and refined, and passed through a 50-80 mesh sieve. However, most of the pulverizing devices currently used in production can only perform single-component pulverization, and the pulverization effect is uneven. This results in a certain proportion of raw materials being screened out by the 50-80 mesh sieve, which greatly reduces the utilization rate of raw materials and increases feed costs to some extent. Therefore, an automatic feeding device and process for mixing and pulverizing raw materials for grouper aquatic feed is proposed. This device can pulverize multiple raw materials, and the pulverized raw materials can be directly mixed by passing through a 50-80 mesh sieve. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding device and process for mixing, crushing and feeding raw materials for grouper aquatic feed, so as to solve the problems mentioned in the background art.

[0009] Preferably, the adjusting assembly includes a fixing rod fixedly installed inside the crushing roller, springs fixedly installed at the left and right ends of the four sides of the fixing rod, a sealing cover fixedly installed outside the springs, four limiting plates fixedly installed at equal angles around the sealing cover, four crushing plates fixedly installed on one side of each of the four limiting plates, and the outside of each of the four crushing plates penetrating the outside of the crushing roller.

[0010] Preferably, the mixing assembly includes a second transmission rod fixedly installed on one side of the crushing roller, an auger fixedly installed on the outside of the second transmission rod, a baffle fixedly installed at equal angles on the outside of the second transmission rod, a scraper fixedly installed on the outer end of the baffle, a third transmission gear fixedly installed on one side of the second transmission rod, the scraper being arc-shaped, and the third transmission gear meshing with the outer edge of the first transmission gear.

[0011] Preferably, the outer wall of the crushing ring is in contact with the inner wall of the fixed shell, the fixed shell is inclined at 15 degrees to the crushing ring, the inner diameter of the crushing ring gradually decreases from left to right, and a discharge hole is provided at one end of the outer side of the crushing ring, the discharge hole being perpendicular to the discharge pipe.

[0012] Preferably, the transmission ring and the interior of the crushing roller are sealed, the sealing cover is connected to the interior of the crushing roller, the sealing cover is made of rubber, and there are eight springs in groups of two, with each group of springs located at the left and right ends of the bottom of the crushing plate.

[0013] Preferably, one end of the elastic sheet is in contact with the outside of the crushing roller in the transmission assembly, the elastic sheet is arc-shaped, the elastic sheet is made of iron, and the elastic sheet and the extrusion block are coated with an anti-corrosion coating.

[0014] This invention also proposes a process for an automatic feeding device for mixing, crushing, and feeding grouper aquatic feed ingredients. The specific process for this automatic feeding device for mixing, crushing, and feeding grouper aquatic feed ingredients is as follows:

[0015] S1: Adjust the distance between the crushing plate and the crushing ring according to the size of the grouper feed bone crushing. Rotate the first transmission rod by the knob. During the rotation of the first transmission rod, the transmission ring is pushed to slide inside the sliding groove under the action of the thread. During the movement of the transmission ring, the gas inside the crushing roller is squeezed. Since the sealing cover is connected to the inside of the crushing roller, the gas inside the crushing roller enters the inside of the sealing cover. The sealing cover is made of rubber. During the movement of the transmission ring, the sealing cover gradually expands and the spring is stretched, pushing the crushing plate outward, thereby reducing the distance between the crushing plate and the crushing ring.

[0016] S2: Place the bone inside the crushing ring through one side of the fixed shell. Since the crushing ring is tilted at 15 degrees, the bone rolls to the other end of the crushing ring under the guidance of gravity. At the same time, since the bone is blocky, it gets stuck between the crushing ring and the crushing roller. Start the drive motor to drive the first transmission gear to rotate. At the same time, the second and third transmission gears mesh with the left and right sides of the first transmission gear, respectively. The first transmission gear drives the second and third transmission gears to rotate. During the rotation of the second transmission gear, the crushing ring rotates forward, while the third transmission gear drives the second transmission rod and the crushing roller to rotate in the opposite direction.

[0017] S3: By rotating the crushing roller and the crushing ring in opposite directions, the first protrusion and the second protrusion are driven to rotate respectively, and the bone between the crushing roller and the crushing ring is initially crushed. After the initial crushing, the bone gradually rolls to the other end of the crushing ring under the guidance of gravity.

[0018] S4: Simultaneously, during the rotation of the crushing roller, four crushing plates are driven to rotate. During the rotation of the four crushing plates, they contact one side of the elastic plate and push the bone inside the crushing ring through the rotation of the crushing plate. The bone will be located between the elastic plate and the crushing plate. Since the elastic plate is made of iron, the bone between the elastic plate and the crushing plate is squeezed by the rotation of the crushing plate, and the bone is crushed into pieces. When the crushing plate is separated from one side of the elastic plate, the elastic plate quickly returns to its original position. The elastic plate will vibrate and break up the crushed bone. Since the inner diameter of the crushing ring gradually decreases from left to right, the bone moves from the left end to the right end through the elastic plate. During the movement, the elastic plate and the crushing plate are gradually squeezed and crushed. After being squeezed and crushed, the bone enters the right end of the crushing ring under the guidance of gravity.

[0019] S5: After being crushed, the bones enter the right end of the crushing ring. The discharge pipe is closed. At this time, various raw materials for grouper are injected into the crushing ring and crushed by the crushing roller and the crushing ring. As the first transmission gear rotates, it drives the second transmission rod to rotate, which in turn drives the auger, baffle and scraper to rotate. During the rotation of the scraper, the raw materials inside the crushing ring are scraped up. As the scraper continues to rotate, the scraped raw materials fall into the top of the baffle and into the outside of the auger, where they can be mixed by the auger. After mixing, the discharge pipe is opened to discharge the grouper feed.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention achieves excellent feed grinding by incorporating a grinding ring, grinding roller, and elastic plates. A drive motor rotates the grinding roller, which in turn rotates four grinding plates. Each grinding plate contacts one side of the elastic plate, and the rotation of these plates pushes the bone inside the grinding ring, placing it between the elastic plates and the grinding plates. The rotating grinding plates compress the bone between the elastic plates and the grinding plates, causing the bone fragments to break apart. Because the inner diameter of the grinding ring gradually decreases from left to right, the bone moves from the left end to the right end of the elastic plates, gradually being crushed between the elastic plates and the grinding plates, thus achieving excellent feed grinding.

[0022] This invention achieves controllable feed grinding size by incorporating springs, transmission rings, and sealing covers. Rotating the first transmission rod with a knob pushes the transmission ring to slide inside the sliding groove. During this movement, the transmission ring compresses the gas inside the grinding roller, causing it to enter the sealing cover. The sealing cover gradually expands, stretching the springs and pushing the grinding plates outwards. This reduces the distance between the grinding plates and the grinding ring, allowing the grinding roller to rotate the grinding plates. The grinding plates then push the elastic plates, compressing the bones between the grinding plates and the elastic plates, thus grinding the bones into smaller pieces and achieving controllable feed grinding size.

[0023] This invention achieves good feed mixing by incorporating scrapers, baffles, and an auger. Multiple raw materials from grouper are injected into the crushing ring, where they are crushed by the crushing roller and the ring itself. As the first transmission gear rotates, it drives the second transmission rod to rotate, simultaneously rotating the auger, baffle, and scraper. During the scraper's rotation, it scrapes up the raw materials inside the crushing ring. Due to the continuous rotation of the scraper, the scraped materials fall onto the top of the baffle and then onto the outside of the auger, thus mixing the various raw materials and achieving a good feed mixing effect.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-9 The present invention provides a technical solution: an automatic feeding device for mixing and crushing raw materials of grouper aquatic feed, including a base 1, a fixed shell 4 fixedly installed on the top of the base 1, a drive component 3 fixedly installed on one side of the fixed shell 4, a discharge pipe 2 fixedly installed on the bottom of the fixed shell 4, a crushing component 8 movably installed inside the fixed shell 4, a transmission component 9 movably installed inside the crushing component 8, an adjustment component 11 movably installed inside the transmission component 9, a mixing component 10 fixedly installed on one side of the transmission component 9, and connecting blocks 6 fixedly installed at the upper and lower ends of one side of the fixed shell 4, and a fixed plate 7 fixedly installed on one side of the two connecting blocks 6.

[0036] The above scheme involves injecting grouper feed bones into the crushing component 8, with the bones positioned between the crushing component 8 and the transmission component 9. Since the fixed shell 4, crushing component 8, and transmission component 9 are tilted at a 45-degree angle, the bones roll towards the right end of the crushing component 8 under the guidance of gravity. Because the bones are blocky, they become lodged between the crushing component 8 and the transmission component 9. The drive component 3 is then activated, causing both the crushing component 8 and the transmission component 9 to rotate. Simultaneously, the crushing component 8 and the transmission component 9 rotate in both directions, crushing the bones between them. The crushed bones gradually shrink in size and move towards the right end of the crushing component 8, thus achieving bone fragmentation. Furthermore, the forward and reverse rotation of the crushing component 8 and the transmission component 9 improves the bone crushing efficiency.

[0037] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the drive assembly 3 includes a drive motor 301 fixedly installed on one side of the fixed housing 4. A first transmission gear 302 is fixedly installed at the output end of the drive motor 301. A second transmission gear 303 is fixedly installed on one side of the crushing assembly 8. The inner edge of the second transmission gear 303 meshes with the outer edge of the first transmission gear 302. One side of the first transmission gear 302 is movably connected to one side of the fixed plate 7.

[0038] The crushing assembly 8 includes a crushing ring 801 movably installed inside the fixed shell 4. Several first protrusions 802 are fixedly installed in a ring at equal angles on the inner wall of the crushing ring 801. Four elastic plates 803 are fixedly installed in a ring at equal angles inside the crushing ring 801. Extrusion blocks 804 are fixedly installed at equal intervals on the outer sides of the four elastic plates 803. The outer wall of the crushing ring 801 is in contact with the inner wall of the fixed shell 4. The fixed shell 4 is inclined at 15 degrees to the crushing ring 801. The inner diameter of the crushing ring 801 gradually decreases from left to right. A discharge hole is opened at one end of the outer side of the crushing ring 801. The discharge hole is perpendicular to the discharge pipe 2.

[0039] The transmission assembly 9 includes a fixed frame 903 fixedly installed on the inner wall of the fixed housing 4. A crushing roller 901 is movably sleeved on the inner wall of the fixed frame 903. The crushing roller 901 is located inside the crushing ring 801. Several second protrusions 902 are fixedly installed on the outer side of the crushing roller 901 at equal angles. A sliding groove 904 is opened on the inner side of the crushing roller 901 at equal angles. A first transmission rod 906 is movably sleeved inside the crushing roller 901. A transmission ring 905 is threaded onto the outer side of the first transmission rod 906. The transmission ring 905 is slidably engaged inside the sliding groove 904. A knob 907 is fixedly installed on one side of the first transmission rod 906.

[0040] Using the above scheme: The bone is placed inside the crushing ring 801 through one side of the fixing shell 4. Since the crushing ring 801 is tilted at a 15-degree angle, the bone rolls towards the other end of the crushing ring 801 under the guidance of gravity. At the same time, because the bone is blocky, it gets stuck between the crushing ring 801 and the crushing roller 901. The drive motor 301 is started to drive the first transmission gear 302 to rotate. Simultaneously, the second transmission gear 303 and the third transmission gear 102 mesh with the left and right sides of the first transmission gear 302, respectively. The first transmission gear 302 drives the second transmission gear 303 and the third transmission gear 102 to rotate. During the rotation of wheel 303, the crushing ring 801 rotates forward, while the third transmission gear 102 drives the second transmission rod 101 and the crushing roller 901 to rotate in the opposite direction, thereby driving the first protrusion 802 and the second protrusion 902 to rotate, which initially crushes the bone between the crushing roller 901 and the crushing ring 801, allowing the bone to smoothly enter between the crushing ring 801 and the crushing roller 901. After the initial crushing, the bone gradually rolls towards the right end of the crushing ring 801 under the guidance of gravity. At the same time, the inner diameter of the crushing ring 801 gradually decreases from left to right, thereby gradually reducing the volume of the bone to the size required for grouper feed.

[0041] It can also transport grouper raw materials, crush and mix them during the transportation process, reduce manual handling of multiple raw materials, thereby reducing labor and improving the efficiency of grouper feed preparation.

[0042] like Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the adjusting assembly 11 includes a fixing rod 112 fixedly installed inside the crushing roller 901. Springs 113 are fixedly installed at the left and right ends of the four sides of the fixing rod 112. A sealing cover 114 is fixedly installed outside the springs 113. Four limiting plates 115 are fixedly installed at equal angles around the sealing cover 114. Four crushing plates 111 are fixedly installed on one side of each of the four limiting plates 115. The outer surfaces of the four crushing plates 111 penetrate the outer surface of the crushing roller 901. The transmission ring 905 and... The interior of the crushing roller 901 is a sealed structure. The sealing cover 114 is connected to the interior of the crushing roller 901. The sealing cover 114 is made of rubber. There are eight springs 113, which are arranged in groups of two. Each group of springs 113 is located at the left and right ends of the bottom of the crushing plate 111. One end of the elastic plate 803 is in contact with the outside of the crushing roller 901 in the transmission assembly 9. The elastic plate 803 is arc-shaped and made of iron. The elastic plate 803 and the extrusion block 804 are coated with an anti-corrosion coating.

[0043] The above scheme is adopted: the distance between the crushing plate 111 and the crushing ring 801 is adjusted according to the size of the bone fragments. The first transmission rod 906 is rotated by the knob 907. During the rotation of the first transmission rod 906, the transmission ring 905 is pushed to slide inside the sliding groove 904 under the action of the thread. During the movement of the transmission ring 905, since the transmission ring 905 and the crushing roller 901 are sealed, the gas inside the crushing roller 901 is compressed. Since the sealing cover 114 is connected to the inside of the crushing roller 901, the gas inside the crushing roller 901 enters the inside of the sealing cover 114. The sealing cover 114 is made of rubber. During the movement of the transmission ring 905, the sealing cover 114 gradually expands and the spring 113 is stretched, pushing the crushing plate 111 outward, thereby reducing the distance between the crushing plate 111 and the crushing ring 801, and then the drive motor 301 is started to drive the crushing plate 111. The crushing roller 901 rotates, driving the four crushing plates 111 to rotate as well. During rotation, each crushing plate 111 contacts one side of the elastic plate 803. The rotating crushing plates 111 push the bones inside the crushing ring 801, placing them between the elastic plate 803 and the crushing plates 111. The crushing plates 111 compress the bones between the elastic plate 803 and the crushing plates 111, crushing the bone clumps under pressure. When the crushing plates 111 detach from one side of the elastic plate 803, the elastic plate 803 quickly resets, vibrating and further breaking up the crushed bones. Because the inner diameter of the crushing ring 801 gradually decreases from left to right, the bones move from the left end to the right end of the elastic plate 803, gradually being crushed between the elastic plate 803 and the crushing plates 111. This results in better crushing of the bone clumps, meeting the needs of grouper feed.

[0044] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the mixing assembly 10 includes a second transmission rod 101 fixedly installed on one side of the crushing roller 901. An auger 103 is fixedly installed on the outside of the second transmission rod 101. A baffle 104 is fixedly installed at equal angles around the outside of the second transmission rod 101. Scrapers 105 are fixedly installed on the outer ends of the baffle 104. A third transmission gear 102 is fixedly installed on one side of the second transmission rod 101. The scraper 105 is arc-shaped. The third transmission gear 102 meshes with the outer edge of the first transmission gear 302.

[0045] Using the above method: Multiple raw materials of grouper are injected into the inside of the crushing ring 801, and crushed by the crushing roller 901 and the crushing ring 801. The raw materials enter the right end of the crushing ring 801. During the rotation of the first transmission gear 302, the second transmission rod 101 is driven to rotate, which in turn drives the auger 103, the baffle 104 and the scraper 105 to rotate. During the rotation of the scraper 105, the raw materials inside the crushing ring 801 are scraped up. As the scraper 105 continues to rotate, the scraped raw materials fall into the top of the baffle 104 and into the outside of the auger 103. The multiple raw materials can then be mixed by the auger 103. After the grouper feed is mixed, it can be discharged by opening the discharge pipe 2.

[0046] This invention also proposes a process for an automatic feeding device for mixing, crushing, and feeding grouper aquatic feed ingredients. The specific process for this automatic feeding device for mixing, crushing, and feeding grouper aquatic feed ingredients is as follows:

[0047] S1: Adjust the distance between the crushing plate 111 and the crushing ring 801 according to the size of the crushed grouper feed bones. Rotate the first transmission rod 906 by the knob 907. During the rotation of the first transmission rod 906, the transmission ring 905 is pushed to slide inside the sliding groove 904 under the action of the thread. During the movement of the transmission ring 905, the gas inside the crushing roller 901 is squeezed. Since the sealing cover 114 is connected to the inside of the crushing roller 901, the gas inside the crushing roller 901 enters the inside of the sealing cover 114. The sealing cover 114 is made of rubber. During the movement of the transmission ring 905, the sealing cover 114 gradually expands and the spring 113 is stretched, pushing the crushing plate 111 to the outside, thereby reducing the distance between the crushing plate 111 and the crushing ring 801.

[0048] S2: The bone is placed inside the crushing ring 801 through one side of the fixed shell 4. Since the crushing ring 801 is tilted at 15 degrees, the bone rolls to the other end of the crushing ring 801 under the guidance of gravity. At the same time, since the bone is blocky, it gets stuck between the crushing ring 801 and the crushing roller 901. The drive motor 301 is started to drive the first transmission gear 302 to rotate. At the same time, the second transmission gear 303 and the third transmission gear 102 mesh with the left and right sides of the first transmission gear 302 respectively. The first transmission gear 302 drives the second transmission gear 303 and the third transmission gear 102 to rotate respectively. During the rotation of the second transmission gear 303, the crushing ring 801 rotates forward, while the third transmission gear 102 drives the second transmission rod 101 and the crushing roller 901 to rotate in the opposite direction.

[0049] S3: By rotating the crushing roller 901 and the crushing ring 801 in both directions, the first protrusion 802 and the second protrusion 902 are driven to rotate respectively, and the bone between the crushing roller 901 and the crushing ring 801 is initially crushed. After the initial crushing, the bone gradually rolls to the other end of the crushing ring 801 under the guidance of gravity.

[0050] S4: Simultaneously, during the rotation of the crushing roller 901, it drives the four crushing plates 111 to rotate. During the rotation of the four crushing plates 111, they contact one side of the elastic plate 803 respectively, and push the bone inside the crushing ring 801 through the rotation of the crushing plates 111. The bone will be located between the elastic plate 803 and the crushing plate 111. Since the elastic plate 803 is made of iron, the bone between the elastic plate 803 and the crushing plate 111 is squeezed by the rotation of the crushing plate 111, and the bone is crushed into pieces. When the crushing plate 111 is separated from one side of the elastic plate 803, the elastic plate 803 quickly returns to its original position. The elastic plate 803 will vibrate and break up the crushed bone. Since the inner diameter of the crushing ring 801 gradually decreases from left to right, the bone moves from the left end to the right end through the elastic plate 803. During the movement, the elastic plate 803 and the crushing plate 111 are gradually squeezed and crushed. After being squeezed and crushed, the bone enters the right end of the crushing ring 801 under the guidance of gravity.

[0051] S5: After being crushed, the bones enter the right end of the crushing ring 801. The discharge pipe 2 is closed. At this time, various raw materials for grouper are injected into the crushing ring 801 and crushed by the crushing roller 901 and the crushing ring 801. During the rotation of the first transmission gear 302, the second transmission rod 101 is driven to rotate, which in turn drives the auger 103, baffle 104 and scraper 105 to rotate. During the rotation of the scraper 105, the raw materials inside the crushing ring 801 are scraped up. As the scraper 105 continues to rotate, the scraped raw materials fall into the top of the baffle 104 and into the outside of the auger 103. The various raw materials can then be mixed by the auger 103. After the mixing is completed, the discharge pipe 2 is opened to discharge the grouper feed.

6. A process for an automatic feeding device for mixing, crushing, and feeding raw materials for grouper aquatic feed, characterized in that: The automatic feeding device for mixing, crushing and feeding grouper aquatic feed ingredients as described in claim 5 includes the following steps: S1: Adjust the distance between the crushing plate (111) and the crushing ring (801) according to the size of the crushed grouper feed bones. Rotate the first transmission rod (906) by the knob (907). During the rotation of the first transmission rod (906), the transmission ring (905) is pushed to slide inside the sliding groove (904) under the action of the thread. During the movement of the transmission ring (905), the gas inside the crushing roller (901) is squeezed. Since the sealing cover (114) is connected to the inside of the crushing roller (901), the gas inside the crushing roller (901) enters the inside of the sealing cover (114). The sealing cover (114) is made of rubber. During the movement of the transmission ring (905), the sealing cover (114) gradually expands and the spring (113) is stretched, pushing the crushing plate (111) to the outside, thereby reducing the distance between the crushing plate (111) and the crushing ring (801). S2: Place the bone inside the crushing ring (801) through one side of the fixed shell (4). Since the crushing ring (801) is tilted at 15 degrees, the bone rolls to the other end of the crushing ring (801) under the guidance of gravity. At the same time, since the bone is in block shape, it gets stuck between the crushing ring (801) and the crushing roller (901). Start the drive motor (301) to drive the first transmission gear (302) to rotate. At the same time, the second transmission gear (303) and the third transmission gear (102) mesh with the left and right sides of the first transmission gear (302) respectively. The first transmission gear (302) drives the second transmission gear (303) and the third transmission gear (102) to rotate respectively. During the rotation of the second transmission gear (303), the crushing ring (801) rotates forward, while the third transmission gear (102) drives the second transmission rod (101) and the crushing roller (901) to rotate in the opposite direction. S3: By rotating the crushing roller (901) and the crushing ring (801) in opposite directions, the first protrusion (802) and the second protrusion (902) are driven to rotate respectively, and the bone between the crushing roller (901) and the crushing ring (801) is initially crushed. After the initial crushing, the bone gradually rolls to the other end of the crushing ring (801) under the guidance of gravity. S4: Simultaneously, during the rotation of the crushing roller (901), it drives the four crushing plates (111) to rotate. During the rotation of the four crushing plates (111), they respectively contact one side of the elastic plate (803), and push the bone inside the crushing ring (801) through the rotation of the crushing plate (111). The bone will be located between the elastic plate (803) and the crushing plate (111). Since the elastic plate (803) is made of iron, the crushing plate (111) squeezes the bone between the elastic plate (803) and the crushing plate (111) through the rotation, thus forming... The bone is crushed. When the crushing plate (111) is separated from one side of the elastic plate (803), the elastic plate (803) quickly returns to its original position. The elastic plate (803) will vibrate and break up the crushed bone. Since the inner diameter of the crushing ring (801) gradually decreases from left to right, the bone moves from the left end to the right end through the elastic plate (803). During the movement, the elastic plate (803) and the crushing plate (111) are gradually squeezed and crushed. The bone after being squeezed and crushed enters the right end of the crushing ring (801) under the guidance of gravity. S5: After being crushed, the bones enter the right end of the crushing ring (801). The discharge pipe (2) is closed. At this time, various raw materials of grouper are injected into the crushing ring (801) and crushed by the crushing roller (901) and the crushing ring (801). The first transmission gear (302) rotates, driving the second transmission rod (101) to rotate. At the same time, the auger (103), baffle (104) and scraper (105) rotate respectively. During the rotation of the scraper (105), the raw materials inside the crushing ring (801) are scraped up. As the scraper (105) continues to rotate, the scraped raw materials fall into the top of the baffle (104) and into the outside of the auger (103). The various raw materials can be mixed by the auger (103). After the mixing is completed, the discharge pipe (2) is opened to discharge the grouper feed.
