Description

Technical Field

[0002] In the feed production process, there is a type of equipment specifically designed to precisely process various raw materials according to a preset formula. It can achieve accurate weighing, conveying and mixing of raw materials through automation, effectively ensuring balanced feed nutrition, improving production efficiency, reducing raw material waste, and reducing safety hazards caused by manual operation. At the same time, it has the ability to flexibly adjust the formula to adapt to diversified production needs. It is a key link in promoting the automation and intelligent development of the feed industry.

[0004] However, in existing technologies, in order to meet the needs of feed for different nutrients, it is necessary to use raw materials with different specific gravities and particle sizes, such as minerals, vitamins, and grains, to achieve nutritional balance. After the feed raw materials are accurately measured and fed, they are mixed and processed by the mixing components. The mixing structure in the existing technology has poor compatibility with the characteristics of the raw materials, making it difficult to cope with raw materials with different specific gravities and particle sizes. It is easy to cause stratification and cannot dynamically adapt to batch differences of raw materials and the mixing needs of different formulas. In addition, the mixing chamber has design defects such as corners and excessive gaps at the bottom, which can create stagnation areas. It may also cause accumulation and cross-contamination due to unreasonable inlet and outlet positions, ultimately resulting in uneven feed mixing and affecting the breeding effect.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-5As shown, this utility model provides a precision feed dispensing device for feed production, including a mixing tank 1. The mixing tank 1 is provided with a feed inlet 11, and a weighing and feeding assembly 2 is fixedly connected to the upper part of the mixing tank 1. The discharge end of the weighing and feeding assembly 2 is located above the feed inlet 11, and a raw material feeding device is connected to the weighing and feeding assembly 2. A stirring mechanism 3 is installed on the upper part of the mixing tank 1. The stirring mechanism 3 includes a first motor 31 and a second connecting shaft 35. A reduction gearbox 32 is fixedly connected to the output end of the first motor 31. The reduction gearbox 32 is fixedly connected to the top of the mixing tank 1. A first connecting shaft 33 is fixedly connected to one end of the output end of the reduction gearbox 32, and a linkage mechanism 5 is fixedly connected to the other end of the output end of the reduction gearbox 32. An inner wall stirring device is fixedly connected to the end of the first connecting shaft 33. The mixing paddle 34 and the end of the second connecting shaft 35 are fixedly connected to the linkage mechanism 5, and the middle mixing paddle 36 is fixedly connected to the surface of the second connecting shaft 35. The bottom of the mixing box 1 is equipped with a discharge pipe 12, and the surface of the discharge pipe 12 is fixedly connected to a control valve. The inner wall mixing paddle 34 is respectively attached to the side wall and bottom wall inside the mixing box 1. The first connecting shaft 33 is rotatably connected to the top of the mixing box 1, and the second connecting shaft 35 is rotatably connected to the top of the mixing box 1. The linkage mechanism 5 includes a first pulley 51, a connecting belt 52 and a second pulley 53. The first pulley 51 is fixedly connected to the output end of the reduction gearbox 32, and the second pulley 53 is fixedly connected to the end of the second connecting shaft 35. The connecting belt 52 is respectively connected to the first pulley 51 and the second pulley 53 for transmission.

[0024] The specific settings and functions of this embodiment are described below. The first motor 31 at the top of the mixing tank 1 is started. Its output, via the reduction gearbox 32, simultaneously drives the first connecting shaft 33 and the first pulley 51 in the linkage mechanism 5. The first connecting shaft 33 drives the inner wall stirring paddle 34 to rotate. This stirring paddle is in contact with the side and bottom walls inside the mixing tank 1, scraping off the attached raw materials. The first pulley 51 drives the second pulley 53 via the connecting belt 52, causing the second connecting shaft 35 to drive the central stirring paddle 36 to rotate synchronously. The weighing and feeding assembly 2 feeds the precisely metered raw materials into the mixing tank from the feed inlet 11. After the feed bin 1, the inner wall stirring paddle 34 and the middle stirring paddle 36 work together to stir the raw materials in all directions. After stirring, the discharge is controlled by the control valve on the surface of the discharge pipe 12. The inner wall stirring paddle 34 eliminates the corners and bottom stagnation areas of the mixing bin 1, and the middle stirring paddle 36 enhances the uniformity of the internal raw material mixing, effectively solving the problem of stratification of raw materials with different specific gravities and particle sizes. At the same time, the linkage mechanism 5 realizes the coordinated operation of the two stirring components, which, together with the precise feeding of the weighing and feeding component 2 and the controllable discharge of the discharge pipe 12, reduces raw material residue and cross-contamination, greatly improves the feed mixing effect, and ensures the breeding effect.

[0025] Example 2: Figures 1-5As shown, a crushing and mixing mechanism 4 is fixedly connected to the upper part of the mixing box 1. The crushing and mixing mechanism 4 includes a second motor 41, which is fixedly connected to the upper part of the mixing box 1. A third connecting shaft 42 is fixedly connected to the output end of the second motor 41. The third connecting shaft 42 is rotatably connected to the top of the mixing box 1, and a crushing blade 43 is fixedly connected to the surface of the third connecting shaft 42.

[0026] The overall effect of this embodiment is as follows: the weighing and feeding assembly 2 feeds precisely measured raw materials into the mixing tank 1 through the feed inlet 11. At the same time, the crushing and mixing mechanism 4 at the top of the mixing tank 1 is activated. The second motor 41 drives the third connecting shaft 42 to rotate, which in turn drives the crushing blades 43 on its surface to rotate at high speed, pre-crushing the incoming raw materials, especially those with lumps or large particles. The crushed raw materials fall into the mixing tank 1. At this time, the stirring mechanism 3 operates synchronously. The first motor 31 drives the first connecting shaft 33 through the reduction gearbox 32, which drives the inner wall stirring paddle 34 to rotate and scrape off the residue against the side and bottom walls of the mixing tank 1. At the same time, the reduction gearbox 32 drives the second connecting shaft 35 and the middle stirring paddle 36 to rotate through the linkage mechanism 5, which works with the crushing blades 43 to form a "crushing-stirring" synergistic effect. Finally, the uniformly mixed feed is discharged through the discharge pipe 12.

[0027] The crushing blades 43 of the crushing and mixing mechanism 4 pre-treat agglomerated raw materials, improving the dispersion of raw materials. Combined with the all-round mixing of the inner wall stirring paddle 34 and the middle stirring paddle 36, it effectively solves the problems of stratification and uneven mixing of raw materials with different specific gravities and particle sizes, reduces stagnation areas and cross-contamination, and significantly improves feed mixing accuracy and production quality.
