Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a feed mixer with an asymmetric paddle structure. Background Technology

[0002] Currently, feed mixers generally adopt symmetrical blade structures, such as double-helix belt mixers or paddle mixers. Although they can achieve basic mixing functions, they suffer from problems such as insufficient mixing uniformity, high energy consumption, and high residue rates. The symmetrical blades have a single movement trajectory, which easily leads to material stratification or uneven local mixing, especially with poor dispersion of trace additives.

[0003] In addition, the unloading structure of traditional mixers is prone to material accumulation, which affects the cleaning efficiency between batches.

[0004] Therefore, there is an urgent need for a feed mixing equipment with optimized structure, higher mixing efficiency, and lower residue rate to meet the requirements of modern feed production for uniformity and energy efficiency. Summary of the Invention

[0005] To solve the above problems, this utility model provides the following technical solution: a feed mixer with an asymmetric blade structure, including a mixing chamber, a drive motor, a main shaft, and a blade assembly. The drive motor is connected to the main shaft via a coupling. Blade assemblies are asymmetrically distributed on the main shaft. Each blade assembly includes at least two asymmetrically distributed first set of blades and second set of blades. The first set of blades is spirally arranged along the main shaft, and the second set of blades is linearly arranged along the main shaft, forming an asymmetric mixing structure.

[0006] Preferably, the installation angle of the first set of blades is 30° to 60°, and the installation angle of the second set of blades is 10° to 30°.

[0007] Preferably, the blade length of the first group of blades is 20% to 50% longer than that of the second group of blades.

[0008] Preferably, the inner wall of the mixing chamber is provided with a guide plate, which is inclined and works with the blade assembly to enhance material flow.

[0009] Preferably, the main shaft has a hollow structure and an internal liquid addition pipe for spraying liquid additives into the mixing chamber.

[0010] Preferably, the bottom of the mixing chamber is provided with an adjustable discharge door, the opening and closing angle of which is adjustable to adapt to the discharge speed of different materials.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: the combination structure of asymmetrically distributed spiral blades and linear blades forms a multi-directional composite motion trajectory, which improves the mixing uniformity and efficiency of materials; the blade design with different angles and lengths enhances shearing and convection, effectively solving the problem of uneven dispersion of trace additives; the combined use of the guide plate and the hollow main shaft liquid addition pipe further optimizes the solid-liquid mixing effect; the adjustable discharge gate structure reduces the material residue rate, making the equipment more adaptable to the production needs of different feed formulations, and the overall features are high mixing quality, low energy consumption, and strong adaptability.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 As shown, the feed mixer with an asymmetric blade structure in this embodiment includes a mixing chamber 1, a drive motor 2, a main shaft 3, and a blade assembly 4. The drive motor 2 is connected to the main shaft 3 via a coupling. The blade assembly 4 is asymmetrically distributed on the main shaft 3. The blade assembly 4 includes at least two asymmetrically distributed first set of blades 401 and second set of blades 402. The first set of blades 401 is arranged spirally along the main shaft 3, and the second set of blades 402 is arranged linearly along the main shaft 3, forming an asymmetric mixing structure.

[0016] The first set of blades 401 has an installation angle of 30° to 60°, and the second set of blades 402 has an installation angle of 10° to 30°.

[0017] The blade length of the first set of blades 401 is 20% to 50% longer than that of the second set of blades 402.

[0018] The inner wall of the mixing chamber 1 is provided with guide plates 5, which are inclined and work with the blade assembly 4 to enhance the flow of materials.

[0019] The main shaft 3 is a hollow structure with a liquid addition pipe 6 inside.

[0020] The opening angle of the discharge gate 7 is adjustable to accommodate different material discharge speeds.

[0021] The working principle of this invention is as follows: The drive motor 2 drives the main shaft 3 to rotate via a coupling, which in turn drives the asymmetrically distributed first set of blades 401 and the second set of blades 402 to work together. The spirally arranged first set of blades 401 pushes the material to form a composite axial and radial flow at an installation angle of 30° to 60°, while the linearly arranged second set of blades 402 generates a strong shearing effect at an installation angle of 10° to 30°. The guide plate 5 on the inner wall of the mixing chamber 1 works in conjunction with the blade group 4 to enhance material convection, and the liquid addition pipe 6 in the main shaft 3 achieves uniform spraying of liquid additives. Finally, the mixed material is discharged through the discharge gate 7 with an adjustable opening angle. This asymmetrical blade structure forms three-dimensional turbulence through differentiated stirring action, which improves the mixing uniformity and efficiency.
