Description

Technical Field

[0001] This utility model relates to the field of concentrated feed mixing and drying, and in particular to a concentrated feed mixing and drying device. Background Technology

[0002] Against the backdrop of the rapid development of modern agriculture and animal husbandry, concentrated feed, as an important source of animal nutrition, has its production efficiency and product quality directly related to the benefits of the breeding industry and the healthy growth of animals. The production process of concentrated feed covers several key links such as raw material crushing, mixing, drying and pelleting. Mixing and drying, as core processes, have a decisive impact on the uniformity of the feed.

[0003] Traditional concentrated feed mixing equipment often uses a single stirring shaft design. When faced with feed raw materials with high viscosity or high moisture content, the material can only be turned over in one direction, resulting in the formation of local eddies during the mixing process, causing uneven mixing and even clumping, which in turn affects the uniformity and quality of the feed. To address these issues, a concentrated feed mixing and drying device is proposed. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a concentrated feed mixing and drying device, which aims to improve the problem in the prior art that "traditional concentrated feed mixing equipment adopts a single stirring shaft design, which can only achieve unidirectional tumbling when facing feed raw materials with high viscosity or high moisture content, resulting in uneven feed mixing, easy clumping, and thus affecting feed uniformity and quality".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concentrated feed mixing and drying device, comprising a body, a servo motor fixedly installed at the top of the body, an auger I provided on the inner wall of the body, a stirring assembly provided inside the body, the stirring assembly comprising a fixed ring, the fixed ring being fixedly connected to the inner wall at the top of the body, an internal gear ring being fixedly connected to the inner wall of the middle part of the fixed ring, a turntable being rotatably connected to the upper and lower parts of the inner wall of the fixed ring near the internal gear ring, a rotating shaft being fixedly connected to the top of the center point of the upper turntable, the rotating shaft passing through the body and fixedly connected to the bottom end of the output shaft of the fixed ring, a gear I meshing with the inner wall of the internal gear ring, the auger I passing through and rotatably connected to the center of the lower turntable, a gear II fixedly connected to the top of the auger I, the gear II meshing with the gear I, and the auger II passing through and fixedly connected to the middle part of the gear I.

[0006] As a further description of the above technical solution:

[0007] The top of the second auger is a smooth surface.

[0008] As a further description of the above technical solution:

[0009] The top of the second auger passes through the lower turntable and is rotatably connected to the bottom of the upper turntable. The first gear and the second auger are positioned on the inner gear ring away from the center.

[0010] As a further description of the above technical solution:

[0011] The top of the machine body is provided with a circulation component, which includes a fan. The fan is fixedly installed at the top of the machine body near the right side, and an air inlet is fixedly connected to the bottom of the fan.

[0012] As a further description of the above technical solution:

[0013] The air inlet is penetrating and fixedly connected to the inside of the machine body and located near the right side, while the air outlet is located at the top of the machine body near the left side.

[0014] As a further description of the above technical solution:

[0015] Three sets of baffles are fixedly connected to the inner wall of the air outlet, and the three sets of baffles are evenly distributed in a circular array. A baffle is rotatably connected to the center of the three sets of baffles.

[0019] The size of the second set of three blocks is compatible with that of the first set of three blocks, and both are set in the shape of fan-shaped blocks.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the rotation of the turntable drives gear one to perform planetary motion along the internal gear ring, so that gear one meshes with the internal gear ring and drives the eccentrically set auger two to rotate and revolve. At the same time, gear one meshes with gear two and drives auger one to rotate. The convective shear force formed by the counter-rotating auger one and auger two breaks the agglomeration of feed particles, thereby improving the mixing efficiency and uniformity and improving the processing quality.

[0022] 2. In this utility model, the air generated by the fan enters the machine body and is evenly diffused to the feed layer inside the machine body. The air pushes the hot air out from the air outlet, taking away the moisture in the feed. As the air flows in the cavity, the air is circulated in the machine body, which further improves the drying effect and ensures that the feed is dried simultaneously during the mixing process, thereby further improving the product quality.

[0028] 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.

[0029] Reference Figures 1-3This utility model provides an embodiment of a concentrated feed mixing and drying device, comprising a body 1, which is the main body of the concentrated feed mixing and drying device. The inner wall of the body 1 is provided with a heating chamber wall, which can be heated by connecting wires. Combined with the stirring and mixing action of an auger 4, the feed can be mixed and dried simultaneously. A servo motor 5 for increasing driving power is fixedly installed at the top of the body 1. The inner wall of the body 1 is provided with an auger 4 for rotating and mixing the feed. A stirring assembly 2 is provided inside the body 1. The stirring assembly 2 includes a fixed ring 21 providing support, which is fixedly connected to the inner wall of the top of the body 1. An inner toothed ring 26 with grooves on its inner wall is fixedly connected to the middle inner wall of the fixed ring 21. Rotary discs 2, which are rotatably connected to the fixed ring 21 and thus provide support, are rotatably connected to the inner wall of the fixed ring 21 near the upper and lower parts of the inner toothed ring 26. 5. A rotating shaft 27 is fixedly connected to the top of the center point of the upper turntable 25, which drives the upper turntable 25 to rotate. The rotating shaft 27 passes through the machine body 1 and is fixedly connected to the bottom end of the output shaft of the fixed ring 21. The inner wall of the internal gear ring 26 is meshed with a gear 22 that meshes with the internal gear ring 26 to form a self-rotating gear. The auger 4 passes through and is rotatably connected to the center of the lower turntable 25. The top of the auger 4 is fixedly connected to a gear 24 that drives the auger 4 to rotate. The gear 24 meshes with the gear 22. The middle of the gear 22 is connected to an auger 23 that cooperates with the auger 4 to further improve the stirring effect. The top of the auger 23 is set with a smooth surface, which can be rotatably connected to both sets of turntables 25. The top of the auger 23 passes through the lower turntable 25 and is rotatably connected to the bottom end of the upper turntable 25. The gear 22 and the auger 23 are set at a position away from the center of the internal gear ring 26.

[0030] Reference Figures 1-3The top of the machine body 1 is equipped with a circulation assembly 3, which includes a fan 31 that blows air into the machine body 1. The fan 31 is model 9-19No.4A and provides strong air circulation power. The motor of the fan 31 is an explosion-proof motor, suitable for feed drying environments where there may be a risk of dust explosion. The fan 31 is fixedly installed on the top of the machine body 1 near the right side. The bottom of the fan 31 is fixedly connected to an air inlet 35. The air inlet 35 has a built-in filter screen with a 1mm aperture to prevent feed particles from being sucked in. The air inlet 35 penetrates and is fixedly connected to the inside of the machine body 1 near the right side. An air outlet 33 is located near the left side of the top. Three sets of baffles 34 are fixedly connected to the inner wall of the air outlet 33. The three sets of baffles 34 are evenly distributed in a circular array. A baffle 32 is rotatably connected to the center of the three sets of baffles 34. The bottom of the baffle 32 is a fan-shaped block with three sets of evenly distributed circular arrays, and its top is a round rod. The three sets of baffles 34 are the same size as the three sets of baffles 32 and are all fan-shaped blocks. Rotating the baffle 32 can adjust the position where the baffle 32 overlaps with the baffles 34, thereby adjusting the size of the air outlet 33 as needed and improving its applicability.

[0031] Working principle: In use, first connect the external power supply and switch to the electrical equipment in this device, start the servo motor 5 to drive the rotating shaft 27 and the upper turntable 25 to rotate around the center of the fixed ring 21, and then drive the gear 22 connected to the upper turntable 25 to make planetary motion along the inner wall of the inner gear ring 26. While revolving, the gear 22 meshes with the inner gear ring 26 to generate its own rotation. When the gear 22 rotates, it meshes with the gear 24 to drive the auger 4 to rotate. The rotation of the auger 4 conveys the feed at the bottom of the machine body 1 upward and performs preliminary mixing. At the same time, the auger 23 fixedly connected to the gear 22 rotates synchronously due to the rotation of the gear 22. Its spiral direction is opposite to that of the auger 4, which performs secondary shearing and mixing of the feed. The auger 23 not only rotates on its own but also moves in a circle along the inner gear ring 26 with the gear 22, forming a composite motion trajectory of rotation and revolution, which improves the uniformity of mixing.

[0032] When the resistance wire inside the heating chamber is energized, it generates heat. The heat is conducted through the inner layer to the feed inside the machine body 1. Under the continuous stirring of auger 1 4 and auger 2 3, the feed comes into full contact with the heating chamber wall, achieving heat conduction drying. At the same time, the feed particles are constantly exposing new surfaces during the turning process, accelerating moisture evaporation. At this time, the fan 31 is started to draw in external air, which enters the machine body 1 through the air inlet 35. The air enters the right side of the machine body 1 through the air inlet 35 and is evenly diffused to the feed layer. Through convection heat exchange, the moisture in the feed is further removed. As the air flows in the chamber, the air pushes the hot air out from the air outlet 33, realizing the circulation of air in the machine body 1 and further improving the drying effect.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
