Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and in particular to a shrimp feed mixing and feeding machine. Background Technology

[0002] Shrimp feed is a specialized feed for shrimp farming, primarily composed of fishmeal, shrimp meal, plant protein, and various vitamins and minerals. It aims to provide shrimp with the comprehensive nutrition needed for growth, promoting healthy development and improving farming efficiency. Shrimp feed formulations can be adjusted according to different shrimp species, growth stages, and farming environments to meet their specific needs. Shrimp feed mixing and dispensing machines are specifically designed for the aquaculture industry, designed for efficient mixing and dispensing of shrimp feed. With the rapid development of aquaculture, the demand for shrimp feed is constantly increasing. To improve feeding efficiency and ensure nutritional balance, the market urgently needs efficient and precise feed processing equipment.

[0003] Shrimp feed processing equipment processes and treats feed through a series of steps. Its basic working principle includes raw material feeding, mixing, crushing, pelleting, and drying. First, the raw materials are conveyed into a mixing tank and uniformly mixed. Then, a crusher refines the large particles. Next, a pellet mill processes the mixed feed into pellets to improve digestibility and absorption. Finally, a dryer removes excess moisture to extend the feed's shelf life.

[0004] Existing shrimp feed processing typically relies on simple agitator mixers or gravity-fed quantitative feeders. Agitation mixers, which use high-speed rotating blades to mix materials, achieve some initial mixing but are prone to fine powder flying and localized over-grinding. In addition, a more advanced vibrating screen-assisted combination device is widely used in certain specific situations. It consists of a primary mixing unit, a fine screening module, and a terminal discharge port. While comprehensive in function, its complex structure and high cost make it unsuitable for widespread use by small and medium-sized shrimp farmers. Therefore, a shrimp feed mixing and feeding machine is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a shrimp feed mixing and feeding machine, which aims to improve the problems of fine powder flying around in the existing technology and its unsuitability for promotion and use by small and medium-sized farmers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shrimp feed mixing and feeding machine includes a housing, a mixing mechanism fixedly connected to the inner wall of the housing, a transmission mechanism fixedly connected to the outside of the mixing mechanism, a vibration mechanism fixedly connected to one side of the transmission mechanism, and a mixing drum fixedly connected to the inner wall of the housing.

[0008] The vibration mechanism includes a rotating rod, with multiple extension blocks fixedly connected to the outside of the rotating rod. A spring is fixedly connected to the inner wall of the extension block. A movable plate is fixedly connected to the other end of the spring. A striking roller is fixedly connected to the other end of the movable plate. The outside of the striking roller contacts the bottom of the mixing tank. A sorting component is fixedly connected to one side of the rotating rod.

[0009] Furthermore, the material is added into the mixing tank through the feed inlet. After the motor is started, the mixing mechanism begins to operate, driving the transmission mechanism to mix. At the same time, the vibration mechanism fixedly connected to one side of the transmission mechanism starts to operate. Its rotating rod rotates, causing multiple extension blocks to rotate. The springs inside the extension blocks are compressed and released, thereby pushing the moving plate to move. The movement of the moving plate causes the impact roller to contact the bottom of the mixing tank, forming an impact force. This effectively stimulates the vibration of the material inside the mixing tank, preventing the material from adhering to the tank wall, thus ensuring the high efficiency and uniformity of mixing. After mixing, the material is smoothly discharged into the feeding box under the action of vibration and impact, and enters the sorting component for subsequent precise sorting. This series of movements ensures the efficient operation of the entire equipment and improves production efficiency.

[0010] As a further description of the above technical solution:

[0011] The mixing mechanism includes a motor, which is externally fixedly connected to the inner wall of the housing. A transmission rod is fixedly connected to the drive end of the motor. A spiral blade is fixedly connected to the outside of the transmission rod. A rubber sheet is fixedly connected to the outside of the spiral blade. The outside of the rubber sheet is in contact with the inner wall of the mixing tank.

[0012] Furthermore, the motor is fixed to the inner wall of the housing, and its drive end is connected to the transmission rod. A spiral blade is fixed to the outside of the transmission rod. After the motor is started, the transmission rod drives the spiral blade to rotate, pushing the material in the mixing barrel forward. The rubber sheet on the outside of the spiral blade contacts the inner wall of the mixing barrel to prevent the material from being scratched and reduce adhesion, thereby improving the mixing efficiency. This design ensures that the material is in full contact and achieves uniform mixing.

[0013] As a further description of the above technical solution:

[0014] The transmission mechanism includes a drive wheel, the drive wheel is fixedly connected to the outside of the transmission rod through a through hole, a driven wheel is rotatably connected to the inner wall of the housing, a belt is coupled to the outside of the drive wheel and the driven wheel, and one side of the driven wheel is fixedly connected to one side of the rotating rod.

[0015] Furthermore, the drive wheel is fixed outside the transmission rod. When the motor is started, the drive wheel rotates, driving the connected belt, which in turn drives the driven wheel to rotate. The driven wheel on the inner wall of the housing is fixedly connected to one side of the rotating rod. Therefore, the rotation of the driven wheel directly drives the rotating rod to move. This design ensures the effective transmission of power, allowing the subsequent vibration mechanism and mixing process to proceed smoothly, thus improving the overall working efficiency.

[0016] As a further description of the above technical solution:

[0017] The sorting assembly includes an extension rod, one side of which is fixedly connected to one side of the rotating rod, and the other end of which is fixedly connected to a drive disk. A rotating ring is rotatably connected to the outside of the drive disk, and a connecting rod is fixedly connected to the outside of the rotating ring. A sorting plate is rotatably connected to the bottom of the connecting rod.

[0018] Furthermore, the rotation of the rotating rod drives the extension rod to move, and the drive disk fixed at the other end of the extension rod rotates accordingly. The rotation of the drive disk drives the connected rotating ring, which in turn pushes the connecting rod to move. The bottom of the connecting rod is connected to the sorting plate, and when it rotates, it causes the sorting plate to move up and down, thereby accurately sorting the materials according to their size. Materials smaller than the size of the sorting plate fall from below, while larger materials are discharged from the side, completing the sorting process.

[0019] As a further description of the above technical solution:

[0020] The bottom of the housing is fixedly connected to a feeding box, and the outer side of the sorting plate is slidably connected to the inner wall of the feeding box.

[0021] Furthermore, the material is discharged through the feeding box, and the feeding box also restricts the sorting plate.

[0022] As a further description of the above technical solution:

[0023] A guide plate is fixedly connected to the inner wall of the mixing tank, and a feed box is fixedly connected to the top of the shell.

[0024] Furthermore, materials are conveyed via guide plates and added via feed boxes.

[0025] As a further description of the above technical solution:

[0026] A protective box is fixedly connected to one side of the housing, and the motor is externally fixedly connected to the inner wall of the protective box.

[0027] Furthermore, the motor is protected by a protective box.

[0028] As a further description of the above technical solution:

[0029] The movable plate is slidably connected to the inner wall of the extension block, and one side of the transmission rod is rotatably connected to the inner wall of the mixing tank.

[0030] Furthermore, by restricting the movement of the moving block by extending the block, the rotation of the drive rod within the mixing tank can be made more stable.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the interaction between the impact roller and the mixing drum effectively prevents dust from flying during the mixing process while ensuring the mixing effect and maintaining a clean working environment. At the same time, the cooperative design of the spiral blades and rubber sheets ensures uniform mixing of materials, avoids the problem of materials sticking to the inner wall of the drum, and improves the utilization rate of feed. In addition, the equipment has a reasonable structure and is easy to operate, making it very suitable for small and medium-sized farmers, promoting their production efficiency and economic benefits, and contributing to the sustainable development of the aquaculture industry.

[0033] 2. In this utility model, the efficient sorting of shrimp feed materials is achieved through the flexible cooperation between the extension rod and the sorting plate. The movement of the rotating rod drives the precise adjustment of the sorting plate, allowing materials smaller than the size of the sorting plate to safely fall through the bottom of the feeding box, while materials larger than the size are discharged from the side, ensuring the accuracy of material sorting.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a shrimp feed mixing and feeding machine, comprising a housing 1, a mixing mechanism 2 fixedly connected to the inner wall of the housing 1, and a transmission mechanism 3 fixedly connected to the outside of the mixing mechanism 2. The transmission mechanism 3 is responsible for efficiently transmitting power to the mixing mechanism 2, making the entire mixing process faster, enhancing the flowability of the material, and thus better promoting uniform mixing.

[0043] The vibration mechanism 4 includes a rotating rod 401, with multiple extension blocks 402 fixedly connected to the outside of the rotating rod 401. When the rotating rod 401 starts to rotate, the extension blocks 402 will rotate accordingly, thereby driving the striking roller 405 to strike. A spring 403 is fixedly connected to the inner wall of the extension block 402, and a moving plate 404 is fixedly connected to the other end of the spring 403. The moving plate 404 is slidably connected to the inner wall of the extension block 402. This design can ensure that the striking roller 405 forms an appropriate rebound through the elastic action of the spring 403 during the process of striking the mixing barrel 9, thereby avoiding continuous pressure on the mixing barrel 9. A sorting component 5 is fixedly connected to one side of the rotating rod 401.

[0044] The outer side of the striking roller 405 contacts the bottom of the mixing barrel 9, so that during the striking process, the material inside the mixing barrel 9 can be effectively excited, promoting the vibration of the material and preventing it from adhering to the inner wall of the mixing barrel 9. Through the impact of the striking roller 405, the material inside the mixing barrel 9 will form an effective flow state with the change of striking frequency, ensuring the uniformity of mixing.

[0045] Specifically, firstly, the material enters the mixing tank 9 through the feed inlet. Driven by the motor 201, the transmission mechanism 3 transmits power to the mixing mechanism 2, causing the spiral blades 203 to rotate rapidly, thereby driving the material to circulate and mix. At the same time, the vibration mechanism 4, through the rotation of the rotating rod 401, drives the extension block 402 and the striking roller 405 to strike, generating additional vibration force and enhancing the fluidity of the material in the mixing tank 9. This vibration not only helps the material to mix evenly, but also avoids the phenomenon of material adhering to the tank wall. The contact between the striking roller 405 and the bottom of the mixing tank 9 makes the internal material vibrate effectively with the change of frequency, thereby ensuring the uniformity of mixing. Finally, the mixed material is smoothly discharged into the discharge box 6, and further graded through the sorting mechanism.

[0046] refer to Figure 2 and Figure 3 The mixing mechanism 2 includes a motor 201, which is externally fixed to the inner wall of the housing 1. The fixed design of the motor 201 ensures stable operation and provides a reliable power source to support the operating efficiency of the entire equipment. A protective box 10 is fixedly connected to one side of the housing 1. This design can effectively protect the motor 201 and prevent external dust and materials from damaging it, ensuring the long-term stable use of the equipment. The external fixed connection of the motor 201 to the inner wall of the protective box 10 not only saves space but also reduces the transmission of noise from the equipment and improves the comfort of the overall working environment. A transmission rod 202 is fixedly connected to the drive end of the motor 201. The design of the transmission rod 202 enables it to effectively transmit the rotational motion generated by the motor 201 to the mixing tank 9.

[0047] One side of the transmission rod 202 is rotatably connected to the inner wall of the mixing tank 9 to ensure that no additional friction and wear are generated when it rotates, thereby improving the transmission efficiency. A spiral blade 203 is fixedly connected to the outside of the transmission rod 202. The rotation of the spiral blade 203 can effectively push the material in the mixing tank 9 forward, ensuring full contact between the materials and achieving a uniform mixing effect. A rubber sheet 204 is fixedly connected to the outside of the spiral blade 203. The rubber sheet 204 contacts the inner wall of the mixing tank 9. The softness of the rubber sheet 204 can prevent the material from being scratched during the mixing process, improve the mixing efficiency, avoid the adhesion of materials, and make the mixing smoother.

[0048] The transmission mechanism 3 includes a drive wheel 301, which is fixedly connected to the outside of the transmission rod 202 through the through hole of the drive wheel 301, making the power transmission more direct and reliable. The inner wall of the housing 1 is rotatably connected to the driven wheel 303. This design ensures the high efficiency of the transmission structure. More precise power control is achieved through the rotation of the driven wheel 303. The drive wheel 301 and the driven wheel 303 are externally coupled by a belt 302. The belt 302 can stably transmit power, reduce energy loss in the transmission process, and ensure the smooth operation of the structure. One side of the driven wheel 303 is fixedly connected to one side of the rotating rod 401, ensuring that when the driven wheel 303 rotates, it can drive the rotating rod 401 accordingly, thereby affecting the operation of the vibration mechanism 4.

[0049] Specifically, after the motor 201 is started, the rotational motion it generates is transmitted to the mixing tank 9 through the transmission rod 202 fixed to the inner wall of the housing 1. The transmission rod 202 is rotatably connected to the inner wall of the mixing tank 9, which improves the transmission efficiency. After the spiral blade 203 connected to the transmission rod 202 rotates, it can effectively push the material in the mixing tank 9, so that it can fully contact and mix evenly. At the same time, the contact of the rubber sheet 204 can prevent the material from being scratched during the mixing process, which enhances the mixing effect. During the mixing process, the driving wheel 301 in the transmission mechanism 3 is connected to the driven wheel 303 through the belt 302, which makes the power transmission stable. The rotation of the driven wheel 303 further drives the rotating rod 401, which enhances the work of the vibration mechanism 4. Through the impact and vibration, the material inside the mixing tank 9 will not stick to the wall, ensuring the smoothness of mixing and feeding. Finally, the mixed material is accurately sorted by the feeding device, ensuring the efficiency and precision of the production process.

[0050] refer to Figure 3 and Figure 5 The sorting component 5 includes an extension rod 501, one side of which is fixedly connected to one side of a rotating rod 401. This connection design can effectively transmit rotational force, so that the movement of the extension rod 501 is coordinated with the operation of the vibration mechanism 4, thereby improving the efficiency of the sorting process. The other end of the extension rod 501 is fixedly connected to a drive disk 502. The design of the drive disk 502 enables it to generate stable power output during rotation, providing support for the subsequent sorting mechanism. The drive disk 502 is externally rotatably connected to a rotating ring 503. The rotation of the rotating ring 503 can transmit kinetic energy to the connecting rod 504. The external rotation and movement of the connecting rod 504 introduce a simple and effective power transmission method, ensuring the efficient operation of the structure. The bottom of the connecting rod 504 is rotatably connected to a sorting plate 505. The movement of the sorting plate 505 can be precisely adjusted according to the size of the material, thereby achieving effective sorting.

[0051] The bottom of the shell 1 is fixedly connected to the feeding box 6, which provides a material collection and discharge channel to ensure that the material falls smoothly and thus does not affect the overall production efficiency. At the same time, the external sliding connection of the sorting plate 505 is to the inner wall of the feeding box 6. This structural design allows the sorting plate 505 to move freely up and down without obstruction, avoiding material blockage. The inner wall of the mixing tank 9 is fixedly connected to the guide plate 7. The function of the guide plate 7 is to guide the material to be evenly distributed during the mixing process and to prevent the eddies generated during the mixing process from causing uneven dispersion of the material. The top of the shell 1 is fixedly connected to the feeding box 8. The reasonable design of the feeding box 8 ensures that the material enters the mixing tank 9 smoothly, starting the entire mixing and sorting process.

[0052] Specifically, the rotation of the rotating rod 401 causes the extension rod 501 to rotate accordingly, driving the drive disc 502 to rotate. The movement of the drive disc 502 further drives the rotating ring 503. This design ensures the stability and efficiency of the structure. The rotation of the rotating ring 503 transfers kinetic energy to the connecting rod 504, which then drives the sorting plate 505 to move up and down, thereby achieving effective sorting of materials. After the materials are mixed, the materials inside the mixing barrel 9 will flow smoothly into the feed box 6. The movement of the sorting plate 505 allows materials smaller than its size to fall through the bottom of the feed box 6, while materials larger than its size are discharged through the side, completing precise sorting. The guide plate 7 ensures that the materials are evenly distributed during the mixing process. The design of the feed box 8 ensures that the materials enter the mixing barrel 9 smoothly, ensuring the efficient operation and continuous production of the entire equipment.

[0053] Working principle: When the equipment is needed, materials are added to the feed box 8, and the materials enter the mixing tank 9 through the feed box 8. At this time, the motor 201 is started, which drives the transmission rod 202 to rotate. The rotation of the transmission rod 202 drives the spiral blade 203 to rotate, and the rotation of the spiral blade 203 drives the rubber sheet 204 to rotate, so that the spiral blade 203 can push the materials to move and mix them.

[0054] When the transmission rod 202 rotates, it also drives the drive wheel 301 to rotate. At this time, the drive wheel 301 rotates and the belt 302 rotates. The rotation of the belt 302 drives the driven wheel 303 to rotate. The rotation of the driven wheel 303 drives the rotating rod 401 to rotate. The rotation of the rotating rod 401 drives the extension block 402 to rotate. The rotation of the extension block 402 drives the impact roller 405 to rotate. The rotation of the impact roller 405 hits the mixing barrel 9. The impact roller 405 pushes the moving plate 404 to compress the spring 403, thereby causing the moving plate 404 to deform and generate elastic potential energy. This allows the impact roller 405 to retract, avoiding contact with the mixing barrel 9. By hitting the mixing barrel 9, the material inside the mixing barrel 9 will vibrate. In conjunction with the rubber sheet 204 contacting the inner wall of the mixing barrel 9, the material is prevented from sticking to the inner wall of the mixing barrel 9.

[0055] Finally, the mixed material is pushed to the feeding box 6 by the spiral blade 203, where it falls to the top of the sorting plate 505. The rotation of the rotating rod 401 drives the extension rod 501 to rotate, which in turn drives the drive disc 502 to rotate. The rotation of the drive disc 502 drives the rotating ring 503 to rotate, which in turn drives the connecting rod 504 to rotate. When the connecting rod 504 moves, it pulls the sorting plate 505 to move, causing materials smaller than the sorting plate 505 to fall through the bottom of the feeding box 6, and materials larger than the sorting plate 505 to fall from the side of the feeding box 6, thus completing the material sorting.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
