Description

Technical Field

[0001] This utility model provides a dispensing device, belonging to the field of feed production technology, and particularly relates to a feed proportioning and dispensing device for animal husbandry. Background Technology

[0002] In pig farming, feed production plays a crucial role, directly impacting pig growth performance, health, and overall profitability. High-quality feed provides pigs with comprehensive and balanced nutrition, meeting their physiological needs at different growth stages, thus promoting rapid growth and healthy development, increasing daily weight gain, and improving feed conversion ratio. The quality and safety of feed also affect the health of the pig herd. Inappropriate feed formulations or contaminated feed can lead to digestive diseases or other health problems, increasing farming costs and medication usage. Furthermore, cost control during feed production significantly impacts profitability. Rational raw material procurement, precise formula design, and efficient processing techniques can reduce feed costs and improve the economic benefits of pig farming. Therefore, feed production is an indispensable and critical link in the pig farming industry chain, requiring farmers' high attention and scientific management.

[0003] Existing feed production facilities typically employ a basic structure that separates mixing and grinding, primarily consisting of independent mixing and grinding equipment. Mixing equipment, such as a mixer, is responsible for uniformly mixing different raw materials; grinding equipment, such as a pulverizer or ball mill, is used to grind the raw materials to the desired particle size. However, this separate structure has some drawbacks.

[0004] First, the separate mixing and grinding processes result in a longer production flow, requiring multiple material transfers and equipment changes, increasing operational complexity and time costs. Second, the independent mixing and grinding equipment makes it impossible to adjust grinding parameters in real time based on the mixing conditions, thus reducing production efficiency and product quality stability. Furthermore, the separate structure requires more equipment and space, increasing equipment investment and floor space costs. Finally, this structure may lead to uneven mixing or low grinding efficiency when processing certain special raw materials, such as ultrafine powders or sticky materials, affecting the final quality of the feed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a feed proportioning and dispensing device for aquaculture, which solves the problems of inaccurate feed dispensing, cumbersome manual operation and uneven mixing in the prior art, realizes automatic proportioning and precise dispensing of feed, and greatly improves aquaculture efficiency and feed utilization.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a feed proportioning and dispensing device for aquaculture, including a mounting bracket, a screening structure placed inside the connecting frame connected between the mounting brackets, a drive motor connected above the screening structure via a mechanically connected drive shaft, an inverted conical outer shell fitted above the connecting frame, and an electrical control center electrically connected to the drive motor located above the outer shell.

[0007] Preferably, the outer casing has a crossbeam rod that is fixedly connected inside and supported by the drive shaft to the drive motor, and the outer casing has a support plate that corresponds to and abuts against its own outer surface.

[0008] Preferably, the mounting bracket includes support rods located on both sides of the outer shell and connected to the support plate, positioning rods located between the support rods and fixedly connected to the connecting frame, and a discharge chute corresponding to itself and the connecting frame is provided below the mounting bracket.

[0009] Preferably, the screening structure includes a grinding roller connected to the drive shaft and an outer grinding plate sleeved on the outside of the grinding roller and engaged with the connecting frame.

[0010] Preferably, both the outer grinding plate and the grinding roller are conical. The outer grinding plate includes an upper grinding plate and a lower grinding plate corresponding to the grinding roller. The inclination rate of the side plate of the lower grinding plate is less than that of the upper grinding plate. The inclination curvature of the side plate of the upper grinding plate is the same as that of the side plate of the grinding roller. The diameter of the grinding roller is smaller than the inner diameter of the upper grinding plate.

[0011] Preferably, there is a certain gap between the grinding roller and the outer grinding plate, allowing feed with a diameter smaller than the gap to enter the discharge trough.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] This feed formulation and dispensing device for aquaculture organically integrates components such as the mounting bracket, connecting frame, screening structure, drive shaft, drive motor, outer shell, and electrical control center, forming a relatively compact and functionally coordinated system. This effectively solves many problems caused by the separation of mixing and grinding in existing feed production equipment. In actual operation, this device eliminates the need for the traditional method of first uniformly mixing raw materials in a separate mixing device such as a mixer, and then transferring them to specialized grinding equipment such as a pulverizer or ball mill for particle size processing. Instead, it combines the mixing and grinding processes into one. In the screening structure, driven by the drive motor, the feed raw materials are ground through the relative motion between the grinding rollers and the outer grinding plate. Simultaneously, guided by the inverted conical structure of the outer shell, the material is evenly distributed and continuously falls. This process itself combines the functions of mixing and grinding, greatly shortening the entire production process and reducing the operational complexity and time costs increased by multiple material transfers and equipment switching. Moreover, since mixing and grinding are carried out simultaneously within the same device, the control center can monitor the production status in real time. Based on the actual mixing and grinding conditions, it can flexibly adjust the grinding intensity and mixing effect by regulating parameters such as the drive motor speed. This ensures improved production efficiency and stable product quality, avoiding the problem of traditional separate structures where independent equipment cannot optimize grinding parameters in a timely manner based on the mixing situation. Furthermore, the integrated design of this device significantly reduces the number and types of equipment required. Compared to traditional multiple independent devices, it greatly saves on equipment investment costs and the floor space required for farming, thus reducing operating costs. For some special raw materials, such as ultrafine powders or viscous materials, the device's unique screening structure design, including the conical structure of the grinding rollers and outer grinding plates and their specific gap settings, effectively prevents uneven mixing or low grinding efficiency, ensuring the reliability and stability of the final feed quality. This provides a more efficient, precise, and economical feed production solution for modern farming.

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.

[0022] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 and Figure 2As shown, a feed dispensing device for aquaculture includes a mounting bracket 1. The mounting bracket 1 is connected to a sieve structure 3 within a connecting frame 2. A drive motor 5 is mechanically connected to the top of the sieve structure 3 via a drive shaft 4. An inverted conical outer shell 6 is fitted onto the top of the connecting frame 2. An electrical control center 111, electrically connected to the drive motor 5, is located on the top of the outer shell 6. A crossbeam rod, penetrated by the drive shaft 4 and supporting the drive motor 5, is fixedly connected inside the outer shell 6. A support plate 112, corresponding to and abutting its own outer surface, is located outside the outer shell 6. The mounting bracket 1 includes support rods 7 located on both sides of the outer shell 6 and correspondingly connected to the support plates 112, and positioning rods 8 located between the support rods 7 and fixedly connected to the connecting frame 2. A discharge chute 9, corresponding to itself and the connecting frame 2, is located below the mounting bracket 1.

[0025] In this embodiment, the screening structure 3 includes a grinding roller 10 connected to the drive shaft 4 and an outer grinding plate 11 sleeved on the outside of the grinding roller 10 and engaged with the connecting frame 2. Both the outer grinding plate 11 and the grinding roller 10 are conical. The outer grinding plate 11 includes an upper grinding plate 12 and a lower grinding plate 13 corresponding to the grinding roller 10. The inclination rate of the side plate of the lower grinding plate 13 is less than that of the upper grinding plate 12. The inclination curvature of the side plate of the upper grinding plate 12 is the same as that of the side plate of the grinding roller 10. The diameter of the grinding roller 10 is smaller than the inner diameter of the upper grinding plate 12. There is a certain gap between the grinding roller 10 and the outer grinding plate 11, allowing feed with a diameter smaller than the gap to enter the discharge trough 9.

[0026] From an implementation perspective, the device provides robust support for the screening structure 3 through the combination of the mounting bracket 1 and the connecting frame 2, ensuring the stability of the screening process. The mechanical connection between the drive shaft 4 and the drive motor 5 enables efficient power transmission, guaranteeing the operational efficiency of the screening structure 3. The design of the outer casing 6 not only protects the internal components but also aids in feed guidance and collection through its inverted conical structure. The electrical connection between the electrical control center 111 and the drive motor 5 enables precise control of the entire screening process, improving the level of automation.

[0027] The conical design and specific gap setting of the grinding roller 10 and the outer grinding plate 11 effectively control the particle size of the feed, ensuring that only feed meeting the requirements can pass through the gap into the discharge trough 9, thereby improving feed quality and utilization. Secondly, the different inclination rates of the upper grinding plate 12 and the lower grinding plate 13 allow for more thorough grinding and grading of the feed during screening, further enhancing the screening effect. Furthermore, the compact structure of the entire device and the rational connection and positional relationship between its components not only save space but also reduce production costs, improving the device's market competitiveness. Finally, the device achieves intelligent control through the electrical control center 111, allowing for adjustments to screening parameters according to different aquaculture needs, demonstrating high flexibility and adaptability, and providing strong technical support for modern aquaculture.

[0028] like Figure 3 and Figure 4 As shown, the screening structure 3 includes a grinding roller 10 connected to the drive shaft 4 and an outer grinding plate 11 sleeved on the outside of the grinding roller 10 and engaged with the connecting frame 2. Both the outer grinding plate 11 and the grinding roller 10 are conical. The outer grinding plate 11 includes an upper grinding plate 12 and a lower grinding plate 13 corresponding to the grinding roller 10. The inclination rate of the side plate of the lower grinding plate 13 is less than that of the upper grinding plate 12. The inclination curvature of the side plate of the upper grinding plate 12 is the same as that of the side plate of the grinding roller 10. The diameter of the grinding roller 10 is smaller than the inner diameter of the upper grinding plate 12. A certain gap exists between the grinding roller 10 and the outer grinding plate 11, allowing feed with a diameter smaller than the gap to enter the discharge trough 9.

[0029] In this embodiment, the grinding roller 10 is typically made of high-strength stainless steel, with a diameter of approximately 150mm and a length customized according to the dimensions of the connecting frame 2, generally between 300mm and 500mm. The outer grinding plate 11 is also made of stainless steel, and its conical design helps to achieve uniform feed distribution and efficient screening. The side plate inclination rates of the upper grinding plate 12 and the lower grinding plate 13 are 15° and 10° respectively. This angle setting ensures that the feed achieves optimal flowability and grinding effect during screening. The gap between the grinding roller 10 and the outer grinding plate 11 is adjustable, commonly set to 2mm to 5mm, to adapt to the screening requirements of feeds with different particle sizes. The drive shaft 4 is connected to the grinding roller 10 using a key connection to ensure the stability and reliability of power transmission. The entire screening structure 3 is fixed to the connecting frame 2 by a snap-fit ​​mechanism, making installation and disassembly convenient, and facilitating maintenance and cleaning. In practical applications, this screening structure 3 can effectively improve the screening efficiency and quality of feed, reduce labor intensity, and provide precise feed formulation and delivery support for the livestock industry.

[0030] When using this feed mixing and dispensing device for livestock, first install the device in a suitable location on the livestock site, ensuring that the mounting bracket 1 firmly supports the entire device. Then, pour the pre-mixed feed ingredients through the top opening of the outer shell 6. At this time, the electrical control center 111 is powered on and started. The drive motor 5 drives the grinding roller 10 in the screening structure 3 to rotate through the drive shaft 4. Under the action of gravity, the feed falls into the conical gap between the grinding roller 10 and the outer grinding plate 11. Due to the special design of the grinding roller 10 and the outer grinding plate 11, the feed is uniformly ground and screened. Feed with qualified particle size falls into the discharge trough 9 below the mounting bracket 1 through the gap. Feed that does not meet the standard continues to move in the conical space under the drive of the grinding roller 10 until it meets the particle size requirements. Throughout the process, the electrical control center 111 can monitor and adjust parameters such as the speed of the drive motor 5 in real time to adapt to the screening requirements of different feeds, ensuring accurate feed mixing and efficient dispensing to meet the nutritional needs of livestock.

[0031] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
