Description

Technical Field

[0001] The present invention relates to the technical field of feed processing, and specifically to an automatic mixing type feed fermentation device and method. Background Art

[0002] In modern animal husbandry, the quality of feed plays a crucial role in the growth and development, health status, and breeding efficiency of livestock. Fermented feed has been increasingly widely used due to its advantages such as improving the nutritional value of feed, enhancing the digestion and absorption rate of animals, and strengthening animal immunity. During the feed production process, multiple raw materials (such as corn, soybean meal, wheat bran, etc.) usually need to be mixed with fermentation inoculants, water, etc. The physical properties and nutritional components of different raw materials vary greatly. If not stirred, it may lead to uneven distribution of raw materials, thereby affecting the production quality of feed.

[0003] However, there are many problems with the existing feed fermentation devices and methods. On the one hand, in the mixing process of traditional feed fermentation devices, most rely on manual or simple stirring devices, making it difficult to achieve uniform mixing of various raw materials. This results in uneven distribution of each component in the feed, affecting the consistency of the fermentation effect, and further causing uneven quality of the fermented feed, unable to meet the requirements of modern animal husbandry for high-quality feed. On the other hand, the existing fermentation devices have a low degree of automation, and the stirring structure is too simple, resulting in uneven stirring of raw materials, which has an adverse impact on the fermentation efficiency and feed quality.

[0004] Therefore, in view of the above situation, there is an urgent need to provide an automatic mixing type feed fermentation device and method to overcome the deficiencies in current practical applications. Summary of the Invention

[0058] A fermenter 1, a mixing tank 4, and a support rod 2. The mixing tank 4 is arranged on the fermenter 1 through the support rod 2, and a discharge pipe 3 communicating with the fermenter 1 is arranged at the bottom of the mixing tank 4. A plurality of feed pipes 5 are arranged at the top of the mixing tank 4;

[0060] And a secondary mixing mechanism for aggregating and mixing the raw materials processed by the primary mixing mechanism.

[0061] In an embodiment of the present invention, different raw materials are batch-added into the premixing chamber 26 through the feed pipes 5, and a fermentation-promoting liquid is added; the fermentation-promoting liquid can be a fermentation inoculant or water; the partitioned mixing assembly is started to mix the raw materials in the premixing chamber 26, so that the raw materials are mixed with the fermentation-promoting liquid. After the mixing is completed, the secondary mixing cylinder 11 is rotated to align the feed port 15 with the premixing chamber 26, and the raw materials in the premixing chamber 26 are discharged into the secondary mixing cylinder 11; after the discharge is completed, the secondary mixing cylinder 11 is reset, and new raw materials are added into the premixing chamber 26, and the above steps are repeated; the lifting mixing assembly is started to mix the various raw materials entering the secondary mixing cylinder 11. After the mixing is completed, the fully mixed raw materials are introduced into the fermenter 1 through the discharge pipe 3 for fermentation.

The arrangement of a plurality of premixing chambers 26 can separately mix different raw materials, facilitating the full mixing of different raw materials with the fermentation-promoting liquid, and preventing the phenomenon that the raw materials with different volumes are mixed simultaneously and easily result in uneven mixing of the raw materials and the fermentation-promoting liquid. The lifting mixing assembly can mix the various fully mixed raw materials together, thereby improving the mixing effect; the fermenter 1 can adopt the existing publicly known technology; compared with the prior art, through the combined setting of the primary mixing mechanism and the secondary mixing mechanism, the present invention avoids the problem that in the prior art, the uneven distribution of each component in the feed easily affects the consistency of the fermentation effect, and further causes the uneven quality of the fermented feed, which cannot meet the requirements of modern animal husbandry for high-quality feed.

[0068] The power unit includes:

[0069] A first driving pipe 6 rotatably installed in the primary mixing cylinder 13, a circular hole for the first driving pipe 6 to penetrate is provided at the top of the mixing tank 4, and a driving module 7 for driving the first driving pipe 6 to rotate is further provided at the top of the mixing tank 4; wherein the driving module 7 can adopt a driving motor and a gear transmission structure, which will not be elaborated here;

[0070] A connecting column 34 rotatably installed at the bottom of the reciprocating frame 27, a linkage square pipe 33 is fixedly installed on the connecting column 34, and one end of the linkage square pipe 33 away from the connecting column 34 is fixedly connected to the first driving pipe 6; wherein a recessed portion for receiving the linkage square pipe 33 is provided at the bottom of the primary mixing cylinder 13, so that the bottom of the linkage square pipe 33 can be flush with the bottom of the primary mixing cylinder 13;

[0071] The stirring unit includes:

[0072] A second driving pipe 35 rotatably installed in the reciprocating frame 27, a support pipe 32 is fixedly installed at the bottom of the second driving pipe 35, and multiple groups of retractable stirring members are provided on the support pipe 32;

[0073] and a second motor 37 fixedly installed in the reciprocating frame 27, the output shaft of the second motor 37 is connected to the second drive tube 35 through a second linkage member 36; the second linkage member 36 can adopt a combined structure of a pulley and a transmission belt. Since the reciprocating frame 27 is an arc-shaped structure, guide wheels for limiting and guiding the transmission belt are provided in the reciprocating frame 27;

[0074] A cavity communicating with the second drive tube 35 is formed in the reciprocating frame 27, and the support tube 32 communicates with the cavity in the reciprocating frame 27 through the second drive tube 35. A first air guide channel communicating with the first drive tube 6 is formed in the linkage square tube 33, and a second air guide channel is formed in the connecting column 34. The first air guide channel communicates with the cavity in the reciprocating frame 27 through the second air guide channel. A conduit 8 is rotatably installed on the first drive tube 6.

[0078] A storage rod 38 arranged in the strip-shaped airbag 28, the storage rod 38 is rotatably connected to the support seat 25 through a support shaft 10, and a torsion spring is further arranged between the storage rod 38 and the support seat 25; the torsion spring can be used to make the storage rod 38 rotate upward or downward along the length direction of the support tube 32 when the strip-shaped airbag 28 is not filled with gas, so that the storage rod 38 can drive the strip-shaped airbag 28 to fit on the surface of the support tube 32 for convenient storage. A limiting structure can also be arranged in the support seat 25 to make the storage rod 38 only able to rotate to a position perpendicular to the support tube 32.

[0079] In this embodiment, after the raw materials enter the premixing chamber 26, the driving module 7 drives the first driving pipe 6 to move forward and backward alternately. Through the cooperative setting of the first driving pipe 6, the linkage square pipe 33 and the connecting column 34, the reciprocating frame 27 can be driven to reciprocate around the first driving pipe 6, and the gas can be introduced into the support pipe 32 through the first driving pipe 6, the linkage square pipe 33, the connecting column 34, the reciprocating frame 27 and the second driving pipe 35. After the gas in the support pipe 32 enters the strip-shaped airbag 28 through the air inlet 39, the strip-shaped airbag 28 will start to expand, and then the strip-shaped airbag 28 will drive the receiving rod 38 to deflect upward or downward, so that the strip-shaped airbag 28 is perpendicular to the support pipe 32, and in cooperation with the reciprocating frame 27 driving the support pipe 32 to reciprocate in the premixing chamber 26 (when reciprocating, the strip-shaped airbag 28 does not collide with the inner wall of the premixing chamber 26), the stirring of the materials in the premixing chamber 26 is realized, and in cooperation with the second motor 37 and the second linkage 36, the second driving pipe 35 can be driven to rotate, so that the support pipe 32 drives the strip-shaped airbag 28 to rotate, further improving the stirring effect. When the end of the reciprocating frame 27 hits the stop block 29, the stop block 29 will contract a certain distance into the installation cavity 30, which is convenient for expanding the stirring range of the strip-shaped airbag 28 and avoiding stirring dead corners. The reciprocating frame 27 can also play a certain role in separating, further enabling the raw materials to be fully mixed with the fermentation-promoting liquid. When feeding, the gas in the strip-shaped airbag 28 is pumped out, which is convenient for the reciprocating frame 27 to drive the strip-shaped airbag 28 to be received into the installation cavity 30 to prevent interfering with the materials entering the premixing chamber 26.

The support bar 23 is fixedly installed on two sections of the elastic telescopic rod 22 close to the top of the secondary mixing cylinder 11. The mixing plates 24 are respectively fixedly installed on the support bar 23 and the third section of the elastic telescopic rod 22, and there is a gap between the mixing plate 24 on the support bar 23 and the elastic telescopic rod 22. Among them, the first linkage 18 adopts a combined structure of a belt pulley and a transmission belt;

[0085] A rotating unit for driving the secondary mixing cylinder 11 to rotate is further arranged in the mixing tank 4.

A first motor 17 is further arranged in the mixing tank 4, and a driving gear 16 meshing with the external gear ring 12 is fixedly installed on the output shaft of the first motor 17.

[0086] In this embodiment, the telescopic member 9 can drive the lifting block 19 to move up and down. The lifting block 19 can drive the rotating plate 20 to move synchronously. When there is less raw material between the secondary mixing cylinder 11 and the rotating plate 20, the telescopic member 9 can move the lifting block 19 upward to compress the mixing space and improve the mixing effect. When the raw material gradually increases, the telescopic member 9 will drive the lifting block 19 to gradually descend to facilitate improving the mixing effect. When the surface of the rotating plate 20 moves to below the opening of the secondary mixing cylinder 11, it is convenient to discharge the mixed material in the secondary mixing cylinder 11. The third motor can drive the rotating plate 20 to rotate. The rotating plate 20 drives the telescopic transmission shaft 21 to rotate, and cooperates with the first linkage 18 to drive the elastic telescopic rod 22 to rotate, so that the mixing plate 24 stirs the raw material. Multiple groups of strip-shaped through holes can be opened on the mixing plate 24 to facilitate improving the turbulence effect. The first motor 17 can drive the secondary mixing cylinder 11 to rotate through the cooperation of the driving gear 16 and the external gear ring 12, so as to facilitate adjusting the position of the feed inlet 15.
