Technical Field
[0001] This utility model relates to the field of feed production technology, specifically to a mixing device for feed production. Background Technology
[0002] Feed production refers to the processing of various raw materials into edible substances that provide animals with the necessary nutrients to promote their growth, health, and production. Feed production occupies an upstream position in the livestock industry chain, serving as a crucial link between crop farming and animal husbandry. The process involves mixing and stirring feed, and feed mixing devices are key equipment used in this process. Their main function is to evenly mix various feed ingredients, ensuring that each portion of feed contains balanced nutrition.
[0003] Traditional mixing devices often suffer from insufficient mixing of materials within the container due to the limited mixing area of the mixing paddle. This results in a certain degree of separation between the upper and lower layers of material, making it difficult to achieve a more uniform mixing process. Furthermore, blockages are prone to occur during the unloading process. Utility Model Content

Detailed Implementation
[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0015] Example: Figure 1-3As shown, this utility model provides a mixing device for feed production, including a tank 1. The tank 1 is in the shape of a vertical cone, and the bottom of the cone-shaped tank 1 is funnel-shaped, which is conducive to the discharge of materials. A mixing device 2 is rotatably installed inside the tank 1. A discharge device 3 is fixedly installed on the lower surface of the tank 1. A support 11 is fixedly installed on the lower surface of the tank 1. A feed inlet 10 is opened on one side of the lower end of the tank 1. The bottom end of the support 11 is provided with four support legs to ensure the stability of the tank 1 during the mixing process and to provide stable support for the tank 1. An inclined feed hopper is installed on one side of the feed inlet 10. The operator can pour the material from the feed hopper into the feed inlet 10, and then the mixing device 2 lifts and mixes the material.
[0016] The stirring device 2 includes a main shaft 22, which is rotatably connected to the upper end of the tank body 1. A first motor 23 is fixedly installed on one side of the tank body 1. Both the output end of the first motor 23 and the upper end of the main shaft 22 are fixedly fitted with pulleys 24. The outer surface of the pulleys 24 is treated with anti-slip material to prevent slippage during the transmission of the synchronous belt 25. The synchronous belt 25 is rotatably fitted onto the outer surface of the pulleys 24. A first stirring paddle 20 is fixedly connected to the bottom end of the main shaft 22. The first stirring paddle 20 is spiral-shaped to facilitate the stirring of materials entering from the bottom through the feed inlet 10. The material is continuously lifted from the bottom to the top by the spiral rotation, and then thrown back to the bottom from the top, achieving the effect of tumbling and mixing. The main shaft 22 is fixedly sleeved with a main gear 26, and the outer surface of the main gear 26 is symmetrically meshed with a secondary gear 27. The size of the main gear 26 is larger than that of the secondary gear 27. The larger main gear 26 brings a faster speed ratio to the secondary gear 27, so that the two secondary gears 27 can drive the first gear 28 to rotate at a faster rotation speed, thereby better driving the second stirring paddle 30 to perform auxiliary mixing and prevent uneven mixing of materials.
[0017] An internal gear ring 21 is fixedly installed on the upper inner wall of the tank body 1. A support frame is fixedly connected to the upper inner wall of the tank body 1. The lower surface of the support frame is fixedly connected to the internal gear ring 21, providing a reasonable support for the internal gear ring 21. The outer surface of the internal gear ring 21 meshes with the outer surface of the secondary gear 27. A first gear 28 is fixedly connected to the lower surface of the secondary gear 27. A second gear 29 meshes with the outer surface of the first gear 28. The first gear 28 and the second gear 29 are of the same size. The first gear 28 and the second gear 29 of the same size can transmit the power brought by the first gear 28 more completely. The second gear 29 is provided so that the two second gears 29 can drive the two second stirring paddles 30 to rotate at the same speed. The second stirring paddles 30 are fixedly sleeved on one side of the second gear 29. The second stirring paddles 30 are symmetrically distributed. Under the drive of the first motor 23, they can drive the first stirring paddle 20 to rotate, lifting and stirring the material from bottom to top. Under the planetary transmission of the main gear 26 and the secondary gear 27, the two second stirring paddles 30 rotate on their own axis and revolve around the main gear 26 as the axis, which helps to perform secondary stirring of the material in the upper layer of the tank 1 and avoids the phenomenon of uneven stirring of the material.
[0018] The unloading device 3 includes a housing 31. A discharge port 32 and a discharge port 33 are respectively opened on both sides of the outer surface of the housing 31. The discharge port 32 communicates with the interior of the tank 1. A second motor 34 is fixedly installed on one side of the housing 31. A rotor impeller 35 is rotatably connected inside the housing 31. The outer surface of the rotor impeller 35 slides against the inner wall of the housing 31, and the width of the rotor impeller 35 is the same as the width of the housing 31, allowing the rotor impeller 35 to completely and evenly distribute the material falling into the housing 31 into the grooves within the rotor impeller 35. The output end of the second motor 34 is fixedly connected to one end of the rotor impeller 35. With the continuous rotation of the rotor impeller 35, quantitative and continuous unloading can be achieved, which is beneficial for the smooth falling of materials, effectively avoiding caking and blockage during the unloading process, and ensuring the continuity and uniformity of unloading.
[0019] Working principle: When mixing is required, the feed mixture is poured in through the feed inlet 10. Then, the first motor 23 in the mixing device 2 is started. The output of the first motor 23 drives the pulley 24 to rotate via the synchronous belt 25, thereby driving the main shaft 22 to rotate vertically. This, in turn, drives the first mixing paddle 20 to rotate spirally. The rotating main shaft 22 drives the main gear 26 to rotate, thereby driving the secondary gears 27 on both sides to rotate synchronously along the inner wall of the internal gear ring 21. This causes the two secondary gears 27 to perform planetary rotation around the main gear 26 as an axis. The rotating secondary gears 27 simultaneously drive the main gear 26 to rotate. The first gear 28 rotates, which in turn drives the second gear 29 to rotate. The rotating second gear 29 drives the second stirring paddles 30 on both sides to rotate and stir inside the tank 1. The spiral blades of the continuously rotating first stirring paddle 20 lift the feed mixture at the bottom of the tank 1 to the top, and then throw it back to the bottom in an umbrella shape, so that the mixture tumbles and stirs inside the tank 1. At the same time, the second stirring paddles 30 on both sides continuously stir the feed mixture accumulated in the tank 1, preventing the feed mixture from settling and clumping, thereby achieving full stirring of the feed mixture.
[0020] When unloading is required, the second motor 34 is started. The output end of the second motor 34 drives the rotor impeller 35 to rotate inside the housing 31. The stirred feed mixture falls from the tank 1 into the groove between the rotor impellers 35 under the action of gravity. As the rotor impellers 35 rotate, the material in the groove continuously falls towards the discharge port 33 by gravity, preventing blockage during unloading, thereby achieving the purpose of automatic unloading.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
