Description

Technical Field

[0001] This utility model relates to the field of fish feed technology, and in particular to an apparatus for preparing fish feed. Background Technology

[0002] Fish feed, a crucial component of aquaculture, has a decisive impact on fish growth, development, health, and final yield. High-quality fish feed not only requires a balanced nutritional composition but also an appropriate particle size to ensure effective intake by fish. Particularly in the core process of fish feed preparation, existing equipment and technologies are increasingly revealing a series of significant limitations and technical problems when handling raw materials of specific shapes and materials.

[0003] Specifically, while the device disclosed in the existing utility model patent CN208466103U has made significant progress in terms of processing hygiene, mixing uniformity, reduction of worker labor intensity, and improvement of automation,

[0004] However, several prominent problems remain in practical operation and application scenarios. The lack of a function to crush and screen fish feed results in inconsistent feed particle sizes; larger particles are difficult for fish to consume normally, thus affecting feed utilization and fish growth rate. Furthermore, the lack of an effective crushing and screening mechanism means that large particles in the feed may clog the feeding system, increasing maintenance costs and potentially posing safety risks to the system. Therefore, given the numerous shortcomings of existing technologies, we urgently need an innovative fish feed preparation device to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a device for preparing fish feed, which solves the problem that the existing technology lacks the function of crushing and screening fish feed, resulting in feed particles of varying sizes. Larger particles are difficult for fish to eat normally, thus affecting the utilization rate of feed and the growth rate of fish.

[0006] To achieve the above objectives, this utility model provides a fish feed preparation device, including a frame, and inclined plates fixedly connected to both sides of the inner side of the frame, and a crushing rod rotatably connected to the upper inner side of the frame.

[0007] A bottom rod is rotatably connected to the lower inner side of the frame, and one end of the bottom rod is connected to one end of the crushing rod by a belt. An inclined screen plate is elastically connected to the lower inner side of the frame, and both ends of the screen plate pass through the two sides of the frame in sequence through side grooves. A drive motor is fixedly connected to one side of the outer wall of the frame by bolts, and one end of the crushing rod passes through the side wall of the frame and is connected to the output shaft of the drive motor. A top frame is fixedly connected to the top of the frame, and a cam is sleeved on the part of the bottom rod located at the bottom of the screen plate.

[0008] One end of the bottom rod and one end of the crushing rod are rotatably connected to the inner wall of the frame through a rotating shaft, and the other end of the bottom rod and the other end of the crushing rod pass through the side wall of the frame through a bearing sleeve.

[0009] Both the bottom rod and the crushing rod are fitted with pulleys, and the two pulleys are connected by a belt winding around each other.

[0010] The lower side of the frame is connected to the door via a hinge, and the top of the frame is equipped with a baffle. The upper sides of the top frame are provided with mounting grooves for use with the baffle.

[0011] The frame has a side plate fixedly connected to the lower side, and the bottom sides of the sieve plate are elastically connected to the top of the side plate and the bottom of the inner side of one of the two side grooves by compression springs.

[0012] The bottom sides of the sieve plate are fixedly connected to the top of the side plate and the bottom of the inner side of one of the two side grooves by telescopic rods.

[0013] This invention relates to a fish feed preparation device. Driven by a motor, the crushing rod efficiently crushes the fish feed, effectively solving the problem of excessively large feed particles and difficulty for fish to consume, caused by the lack of crushing function in existing technologies. The reasonable gap design between the two inclined plates guides the crushed material to fall evenly onto the screen plate, preventing material accumulation and ensuring efficient subsequent screening. The screen plate adopts an inclined structure and is elastically connected to the frame via side grooves. Under the periodic compression of the cam, it achieves continuous vibration, effectively screening the crushed fish feed, further refining particle size, ensuring uniform particle size in the finished feed, and improving feed utilization. A belt links the crushing rod and the bottom rod, enabling multi-functional operation, reducing the need for additional power sources, and improving energy efficiency. The vibration mechanism of the screen plate not only improves screening efficiency but also prevents material from clogging the screen holes, reducing maintenance frequency and failure rate during equipment operation, and enhancing the stability and safety of the device. The overall structure is compact, easy to operate, and highly automated, meeting the large-scale production needs of the aquaculture industry for high-quality fish feed. Attached Figure Description

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 ,

[0023] A fish feed preparation device includes a frame 1, and inclined plates 16 are fixedly connected to both sides of the inner side of the frame 1, and a crushing rod 15 is rotatably connected to the upper inner side of the frame 1.

[0024] A bottom rod 7 is rotatably connected to the lower inner side of the frame 1, and one end of the bottom rod 7 is connected to one end of the crushing rod 15 by a belt 9. An inclined screen plate 12 is elastically connected to the lower inner side of the frame 1, and both ends of the screen plate 12 pass through the two sides of the frame 1 in sequence through the side grooves 10. A drive motor 6 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and one end of the crushing rod 15 passes through the side wall of the frame 1 and is connected to the output shaft of the drive motor 6 for transmission. A top frame 3 is fixedly connected to the top of the frame 1, and a cam 17 is sleeved on the part of the bottom rod 7 located at the bottom of the screen plate 12.

[0025] First, the fish feed raw materials to be processed are fed into the device through the top frame 3 set at the top of the frame 1. After the drive motor 6 is started, the output shaft of the drive motor 6 drives the crushing rod 15 to rotate. The crushing rod 15 performs preliminary crushing of the fish feed entering its working area, reducing its particle size. The crushed fish feed falls from the gap between the two inclined plates 16 set on both sides of the crushing rod 15 onto the screen plate 12 located on the lower inner side of the frame 1. At the same time, one end of the crushing rod 15 is connected to one end of the bottom rod 7 through the belt 9, thereby driving the bottom rod 7 to rotate synchronously. During the rotation of the bottom rod 7, it drives the upper sleeve The cam 17 rotates together with the screen plate 12. During the rotation, the cam 17 periodically applies a squeezing force to the bottom of the screen plate 12. Since the screen plate 12 is connected to the frame 1 by side grooves 10 at both ends, it vibrates up and down under the combined action of periodic squeezing force and its own elasticity. This vibration causes the fish feed particles on the screen plate 12 to be continuously screened. Smaller particles pass through the screen holes and fall down smoothly, while larger particles are left on the surface of the screen plate 12 and move towards the inclined direction of the screen plate 12 with the vibration. Finally, they are discharged from the end of the screen plate 12 or recycled for further processing, thus realizing the continuous operation of fish feed crushing and screening.

[0026] Furthermore, one end of the bottom rod 7 and one end of the crushing rod 15 are rotatably connected to the inner wall of the frame 1 via a rotating shaft, and the other end of the bottom rod 7 and the other end of the crushing rod 15 pass through the side wall of the frame 1 via a bearing sleeve. After the drive motor 6 starts, the crushing rod 15 begins to rotate and drives the bottom rod 7 to rotate synchronously via the belt 9, ensuring that the two key components can operate smoothly and efficiently, while reducing frictional loss, extending the service life of the equipment, and achieving the effect of improving the overall stability and durability of the device.

[0027] Furthermore, pulleys 8 are fitted onto one end of the bottom rod 7 and one end of the crushing rod 15, and the two pulleys 8 are connected by a belt 9. While the drive motor 6 drives the crushing rod 15 to rotate, the pulleys 8 and belt 9 transmit power to the bottom rod 7, causing the cam 17 on the bottom rod 7 to rotate synchronously. This not only realizes the linkage control of the crushing and screening processes, but also simplifies the design of the transmission system, reduces the need for additional power sources, and achieves the effect of improving energy utilization efficiency and reducing energy consumption.

[0028] Furthermore, a door 2 is hinged to the lower side of the frame 1, and a baffle 4 is provided on the top of the frame 1. Mounting grooves 5, which work in conjunction with the baffle 4, are provided on both sides of the upper part of the top frame 3. After the fish feed is crushed and screened, the door 2 can be opened to easily clean the residual material on the screen plate 12 or perform maintenance. The design of the baffle 4 and mounting grooves 5 effectively prevents material spillage during feeding, maintains a clean working environment, improves the ease of operation and cleaning / maintenance of the equipment, and ultimately enhances the user experience and reduces downtime.

[0029] Furthermore, a side plate 14 is fixedly connected to the lower side of the frame 1, and both sides of the bottom of the screen plate 12 are elastically connected to the top of the side plate 14 and the inner bottom of one of the two side grooves 10 respectively through compression springs 11. When the cam 17 periodically squeezes the screen plate 12, the compression spring 11 provides the necessary elastic restoring force, so that the screen plate 12 can effectively screen materials under vibration. The elastic support structure not only enhances the vibration effect of the screen plate 12, but also avoids damage to the screen plate 12 caused by hard collision, thus achieving the effect of improving screening efficiency and protecting equipment safety.

[0030] Furthermore, both sides of the bottom of the screen plate 12 are fixedly connected to the top of the side plate 14 and the inner bottom of one of the two side grooves 10 respectively through telescopic rods 13. When the screen plate 12 is squeezed by the cam 17 and vibrates up and down, the telescopic rods 13 play a guiding role, ensuring that the screen plate 12 always maintains horizontal stability during vibration, avoiding uneven screening caused by offset or tilt. The telescopic rods 13 can also withstand a certain impact force, further protecting the safety of the screen plate 12 and other internal components, thereby enhancing screening accuracy and extending the service life of the equipment.

[0031] In summary:

[0032] First, the fish feed raw materials to be processed are fed into the device through the top frame 3 set at the top of the frame 1. After the drive motor 6 is started, the output shaft of the drive motor 6 drives the crushing rod 15 to rotate. The crushing rod 15 performs preliminary crushing of the fish feed entering its working area, reducing its particle size. The crushed fish feed falls from the gap between the two inclined plates 16 set on both sides of the crushing rod 15 onto the screen plate 12 located at the lower inner side of the frame 1. At the same time, one end of the crushing rod 15 is connected to one end of the bottom rod 7 through the belt 9. Specifically, the two ends of the crushing rod 15 and the bottom rod 7 are respectively rotatably connected to the inner wall of the frame 1 through the rotating shaft. The bearing sleeve penetrates the side wall of the frame 1 to ensure stable operation. Simultaneously, pulleys 8 are fitted onto one end of both the crushing rod 15 and the bottom rod 7. The pulleys 8 are connected by a belt 9, causing the bottom rod 7 to rotate synchronously. During rotation, the bottom rod 7 drives the cam 17 fitted onto it to rotate as well. The cam 17 periodically applies pressure to the bottom of the screen plate 12 during rotation. Since the screen plate 12 penetrates both sides of the frame 1 through side grooves 10 and forms an elastic connection with the frame 1, it vibrates up and down under the combined action of periodic pressure and its own elasticity. The bottom sides of the screen plate 12 are respectively connected to... The side plate 14, fixed to one side of the lower part of the frame 1, and the inner bottom of one of the side grooves 10 are elastically connected. This structure provides the necessary restoring force for the sieve plate 12, enhances the vibration effect, and prevents damage caused by hard impacts. In addition, the bottom sides of the sieve plate 12 are also fixedly connected to the top of the side plate 14 and the inner bottom of one of the side grooves 10 respectively by telescopic rods 13. The telescopic rods 13 play a guiding role, ensuring that the sieve plate 12 maintains horizontal stability during vibration and avoids uneven screening caused by offset or tilt. This vibration causes the fish feed particles on the sieve plate 12 to be continuously screened. Smaller particles pass smoothly through the sieve holes and fall down, while larger particles... The particles are left on the surface of the screen plate 12 and move towards the inclined direction of the screen plate 12 with vibration, and are finally discharged from the end of the screen plate 12 or recycled for further processing, thus realizing continuous operation of fish feed crushing and screening. The operation of the whole device is simple and efficient, and the equipment runs smoothly and reliably. Users can easily clean the residual materials on the screen plate 12 or perform maintenance through the door 2 connected by a hinge on the lower side of the frame 1. At the same time, the top of the frame 1 is equipped with a baffle 4, and the upper sides of the top frame 3 are provided with mounting grooves 5 for use with the baffle 4. This design effectively prevents the material from overflowing during the feeding process, keeps the working environment clean, and improves the convenience of operation and user experience.First, the design of the crushing rod 15 combined with the inclined plate 16 can effectively crush large-particle feed, improving the palatability and utilization rate of the feed and preventing fish from refusing to eat due to excessively large particles. Second, the vibrating screening mechanism of the screen plate 12 combined with the cam 17, the compression spring 11, and the telescopic rod 13 not only improves screening efficiency but also prevents screen hole clogging, reducing equipment failure rate and maintenance frequency. Third, the crushing rod 15 and the bottom rod 7 are linked by the pulley 8 and the belt 9, realizing synchronous control of the crushing and screening processes, reducing the need for additional power source configuration, improving energy utilization efficiency, and reducing energy consumption. Fourth, the setting of the door 2, the baffle 4, and the mounting groove 5 improves the ease of operation and cleaning and maintenance efficiency of the equipment, and extends the service life of the equipment. Fifth, the overall structure is compact and reasonable, with a high degree of automation, and is suitable for the continuous production needs of high-quality fish feed for large-scale aquaculture enterprises. In summary, this invention provides a fish feed preparation device that integrates crushing and screening, is stable in operation, energy-saving and environmentally friendly, and easy to maintain. It truly makes up for the defects of existing technologies, such as uneven feed particles, low utilization rate, and easy clogging of the feeding system caused by the lack of integrated crushing and screening functions. It has significant technological progress and practical value, and provides strong support for the development of the modern aquaculture industry.
