Description

Technical Field

[0001] This utility model belongs to the technical field of raw material mixing equipment, and particularly relates to a mixing device for veterinary drug raw materials. Background Technology

[0002] With the rapid development of animal husbandry, veterinary drug manufacturing technology is constantly innovating. The industry is committed to developing highly effective and safe veterinary drug products to meet the needs of animal disease prevention and healthy breeding. Veterinary drug production requires mixing raw materials. Currently, most drug mixing equipment uses a horizontal rotary stirring structure. The rotational motion of the stirring rod in the horizontal plane mainly produces radial mixing, but the axial (vertical) material exchange capacity is severely insufficient. Drugs in the upper layer of the mixing container are difficult to penetrate downwards due to gravity, while drugs in the lower layer cannot effectively move upwards, forming a significant vertical stratification phenomenon. Drugs at the same height cannot be fully mixed with drugs at other heights. Insufficient mixing will lead to quality problems such as uneven content and inaccurate dosage in subsequent processes, directly affecting the effectiveness of the drug. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a mixing device for veterinary drug raw materials.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mixing device for veterinary drug raw materials includes a mixing tank; the bottom of the mixing tank is frustum-shaped and the top is cylindrical.

[0006] The mixing barrel is provided with a feeding hopper at the top and a discharge pipe at the bottom; the two discharge pipes are symmetrically arranged at both ends of the bottom of the mixing barrel.

[0007] The mixing barrel is equipped with a first rotating shaft, the bottom of which is rotatably connected to the bottom of the mixing barrel, and the top of which extends out of the mixing barrel and is connected to the output end of the motor.

[0008] A first stirring rod is rotatably mounted on the first rotating shaft. The first stirring rod is arranged in a linear array along the axial direction of the first rotating shaft and is symmetrically distributed along the circumference of the first rotating shaft.

[0009] The first rotating shaft has a hollow structure, and a linkage component is provided inside the first rotating shaft;

[0010] One end of the first stirring rod extends into the first rotating shaft and is connected to the linkage component, which drives the first stirring rod to rotate.

[0011] The first stirring rod is provided with a second stirring rod, and the second stirring rod is arranged in a linear array along the axial direction of the first stirring rod;

[0012] A third stirring rod is symmetrically provided on the lower side of the first rotating shaft. The bottom of the third stirring rod abuts against the inner bottom of the mixing tank, and a fourth stirring rod is provided on the top of the third stirring rod.

[0013] A material distribution ring is fixedly connected to the upper side of the first rotating shaft via a connecting rod. The material distribution ring has a triangular cross-section and is located below the feed hopper.

[0014] Through the above technical solution, the raw materials enter the mixing tank through the feeding hopper and are dispersed by the material distribution ring. The motor drives the first rotating shaft to rotate, which in turn drives the first and third stirring rods to revolve. At the same time, under the action of the linkage component, the first stirring rod rotates on the side of the first rotating shaft, thereby driving the second stirring rod to rotate with the first stirring rod. This allows the raw materials to be stirred on different horizontal and vertical planes, enabling the raw materials at different heights to be mixed crosswise, making the raw materials more uniform and faster, and improving the production quality of subsequent medicines.

[0015] Furthermore, the linkage assembly is provided in multiple sets and arrayed along the axial direction of the first rotating shaft, corresponding to the first stirring rod. The linkage assembly includes a first bevel gear and a second bevel gear. A fixed rod is provided inside the first rotating shaft. The two ends of the fixed rod are fixedly connected to the top and bottom of the mixing tank, respectively. The first bevel gear is fixedly mounted on the fixed rod and is coaxially arranged with the fixed rod.

[0016] Two second bevel gears are symmetrically positioned above the first bevel gear and mesh with it.

[0017] The first stirring rod extends into the first rotating shaft and is connected to the side of the second bevel gear, and is coaxial with the second bevel gear.

[0018] Through the above technical solution, the first rotating shaft drives the first stirring rod to revolve, while simultaneously driving the second bevel gear to revolve around the first bevel gear. Through the meshing connection between the second bevel gear and the first bevel gear, the revolve of the second bevel gear drives the first stirring rod to rotate. While the first stirring rod stirs the material horizontally, it also drives the second stirring rod to stir the material vertically.

[0019] Furthermore, the first rotating shaft has multiple support plates inside, corresponding to the first bevel gear;

[0020] The first bevel gear is mounted on the top of the support plate via a bearing, and the fixing rod passes through the support plate and is rotatably connected to the support plate.

[0021] Through the above technical solution, the support plate plays a supporting role for the first bevel gear.

[0022] Furthermore, a first support rod is rotatably provided on the opposite side of the two second bevel gears, a second support rod is provided on the side of the first support rod, and the bottom of the second support rod is rotatably provided on the top of the first bevel gear.

[0023] Through the above technical solution, the first support rod and the second support rod play an auxiliary supporting role in the revolution and rotation of the second bevel gear.

[0024] Furthermore, the second stirring rod is inclined, and the second stirring rods located above and below the first stirring rod are inclined in parallel directions and are staggered.

[0025] The fourth stirring rod is inclined and disposed on the surface of the third stirring rod.

[0026] The above technical solution can make the raw materials more uniformly mixed in the vertical direction.

[0027] Furthermore, the bottom side of the first rotating shaft is inclined and tilted towards the discharge pipe.

[0028] The above technical solution avoids material retention due to the gap between the first rotating shaft and the discharge pipe.

[0029] Furthermore, the bottom of the mixing tank is provided with support legs to support the mixing tank.

[0030] Furthermore, the material distribution ring is provided with multiple through holes of different diameters.

[0031] Through the above technical solution, the raw material through the through hole falls with the inertial rotation of the distribution ring, which delays the vertical falling speed of the raw material and better disperses the raw material into the mixing tank.

[0032] This utility model has the following beneficial effects:

[0033] 1. Raw materials enter the mixing tank through the feed hopper and are dispersed by the distribution ring. The motor drives the first rotating shaft to rotate, which in turn drives the first and third stirring rods to revolve. At the same time, under the action of the linkage component, the first stirring rod rotates on its own side of the first rotating shaft, thereby driving the second stirring rod to rotate with the first stirring rod. This allows the raw materials to be stirred on different horizontal and vertical planes, enabling the raw materials at different heights to be mixed crosswise, making the raw materials more uniform and faster, and improving the production quality of subsequent medicines.

[0034] 2. While the first rotating shaft drives the first stirring rod to revolve, it also drives the second bevel gear to revolve around the first bevel gear. Through the meshing connection between the second bevel gear and the first bevel gear, the revolve of the second bevel gear drives the first stirring rod to rotate. While the first stirring rod stirs the material horizontally, it also drives the second stirring rod to stir the material vertically. Attached Figure Description

A rotating shaft 2 is internal and connected to a linkage assembly, which drives the first stirring rod 21 to rotate. The first stirring rod 21 is provided with a second stirring rod 22, which are arranged in a linear array along the axial direction of the first stirring rod 21. The second stirring rods 22 are inclined, and the second stirring rods 22 above and below the first stirring rod 21 are parallel in their inclination direction and are staggered. A fourth stirring rod 24 is inclined on the surface of the third stirring rod 23. The third stirring rod 23 is symmetrically provided on the lower side of the first rotating shaft 2. The bottom of the third stirring rod 23 abuts against the inner bottom of the mixing tank 1, and the top of the third stirring rod 23 is provided with the fourth stirring rod 24. A material distribution ring 4 is fixedly connected to the upper side of the first rotating shaft 2 through a connecting rod 41. The material distribution ring 4 has a triangular cross section and is located below the feed hopper 11. The material distribution ring 4 has multiple through holes 42 of different diameters to better disperse the raw materials into the mixing tank 1.

[0048] Specifically, the linkage assembly has multiple sets arranged in an array along the axial direction of the first rotating shaft 2, corresponding to the first stirring rod 21. The linkage assembly includes a first bevel gear 31 and a second bevel gear 32. A fixing rod 3 is provided inside the first rotating shaft 2. The two ends of the fixing rod 3 are fixedly connected to the top and bottom of the mixing tank 1, respectively. The first bevel gear 31 is fixedly mounted on the fixing rod 3 and is coaxially arranged with the fixing rod 3. Two second bevel gears 32 are symmetrically arranged above the first bevel gear 31 and mesh with the first bevel gear 31. The first stirring rod 21 extends into the first rotating shaft 2. One end of the shaft 2 is connected to the side of the second bevel gear 32 and is coaxially arranged with the second bevel gear 32.

[0049] The working principle of this utility model is as follows: The motor 25 drives the first rotating shaft 2 to rotate simultaneously, which in turn drives the distribution ring 4 to rotate synchronously. Raw materials enter the mixing tank 1 from the feed hopper 11 and are distributed through the two inclined sides of the distribution ring 4, preventing them from accumulating below the feed hopper 11. As the distribution ring 4 rotates, the raw materials fall into the through hole 42. Due to inertia, they fall while the distribution ring 4 rotates, achieving better distribution. Simultaneously, the raw materials fall into the mixing tank 1. The first stirring rod 21 and the third stirring rod 23 stir the raw materials horizontally. When the first stirring rod 21 rotates horizontally with the first rotating shaft 2, the second bevel gear 32 rotates accordingly. Since the first bevel gear 31 is fixed, the second bevel gear 32 rotates, thereby driving the first stirring rod 21 to rotate and the second stirring rod 22 to stir vertically, achieving mixing of raw materials at different heights. Furthermore, during the rotation of the second bevel gear 32, the first support rod 34 and the second support rod 35 provide better support for the second bevel gear 32.
