Description

Technical Field

[0001] The utility model relates to the field of feed processing equipment, in particular to a feed mixing device. Background Art

[0002] During the feed processing process, a mixer is required to mix multiple components; the utility model patent with application number: CN202320072790.9 discloses a feed mixer, which stirs the material in the tank body through the stirring blades in the stirring tank body. Although it can quickly and generally mix the material evenly, the dispersion speed of the material is relatively slow locally, that is, this stirring method is not fine enough. Moreover, the disadvantage of blade stirring is that there are prone to stirring dead corners. Therefore, this patent drives the stirring tank to rotate as a whole through a gear set to stir the material in the tank body. The stirring tank is relatively bulky, which leads to high overall power and high energy consumption of the equipment. In addition, the exposed stirring tank rotates, which poses a greater safety risk. Summary of the Invention

[0016] In conjunction with the accompanying drawings, the utility model includes a cylinder 1, the bottom of the cylinder 1 is conical, and the lower end of the cone is connected to a material pipe 2. The material pipe 2 is a two-stage stepped shape with a thin upper section and a thick lower section. A first rotating shaft 3 is provided at the axis of the cylinder 1. A radial stirring rod 4 is fixed on the outer wall of the first rotating shaft 3. The first rotating shaft 3 drives the stirring rod 4 to rotate to stir the material in the cylinder 1. A second rotating shaft 5 is provided at the axis of the material pipe 2. A receiving plate 6 is installed on the second rotating shaft 5. The receiving plate 6 is located in the thick section of the material pipe 2, and the receiving plate 6 is open upward. The material in the cylinder 1 will fall into the receiving plate 6 through the material pipe 2. The receiving plate 6 rotates with the second rotating shaft 5. The material in the receiving plate 6 will fly out from the plate mouth under the action of centrifugal force, and hit the stepped surface and inner wall of the material pipe 2 to be dispersed, and then fall to the lower end of the material pipe 2; an inclined material trough 7 is provided at the lower end of the material trough 7. A vertical spiral auger 8 is provided at the lower end of the material trough 7, and the upper end of the spiral auger 8 extends to the upper end of the cylinder 1; the material falling through the material pipe 2 is returned to the cylinder 1 by the spiral auger 8 for circulating stirring.

[0017] The stirring rods 4 are vertically distributed in multiple groups on the first rotating shaft 3, and each group includes multiple stirring rods evenly distributed around the circumference, which can improve stirring efficiency.

[0018] The inner ends of the stirring rods 4 in the same group are fixed to the outer wall of the same sliding sleeve 9. The sliding sleeve 9 is installed on the first rotating shaft 3 via a flat key 10. An axial limit sleeve 11 is provided between every two adjacent sliding sleeves 9 and is sleeved on the first rotating shaft 3. The stirring rods 4 can be replaced in groups when damaged.

[0019] The lower end of the first rotating shaft 3 and the lower end of the second rotating shaft 5 are connected together via a bearing 12. The connection of the two rotating shafts can improve the rigidity of the rotating shafts and prevent the rotating shafts from swinging.

[0020] The lower end of the material trough 7 is provided with a discharge port 13, and a baffle 14 is hinged on the discharge port 13. The baffle 14 is controlled to open and close by a cylinder. After the mixing is completed, the baffle 14 is opened and the material is discharged from the discharge port 13.

[0021] When the present invention is in use, materials are added into the cylinder 1 from the upper end of the cylinder 1, and the first rotating shaft 3 drives the multiple groups of stirring rods 4 to rotate, stirring the materials in the cylinder 1 as a whole, so that the materials in the cylinder 1 are generally mixed evenly; while stirring, the materials in the cylinder 1 will continue to fall into the receiving tray 6 through the material pipe 2. After the receiving tray 6 receives the materials, the materials fly out from the plate mouth of the receiving tray 6 under the action of the centrifugal force when the receiving tray 6 rotates, and the materials hit the stepped surface of the material pipe 2 or the inner wall of the material pipe 2, so that the materials are dispersed and mixed more finely; after flying out of the receiving tray 6, the materials fall into the material trough 7 below and slide to the lower end of the material trough 7, and then are transported upward by the spiral auger 8, and fall into the cylinder 1 from the upper end of the cylinder 1 again for circulation.

[0022] The second rotating shaft 5 rotates at a faster speed, so that the materials in the receiving tray 6 have sufficient centrifugal force to fly out of the receiving tray 6. The first rotating shaft 3 rotates at a slower speed due to the larger stirring resistance. The ends of the first rotating shaft 3 and the second rotating shaft 5 are connected by bearings 12, which does not affect their respective rotations and can improve the rigidity of the two rotating shafts to avoid rotating shaft swing.

[0023] The material of the utility model is stirred by the stirring rod 4 in the cylinder 1, so that the material is generally mixed evenly, and then falls into the receiving plate 6 and scatters and collides under the action of centrifugal force to mix some of the materials more finely. In the manner of first the whole and then the parts, the material can be mixed evenly more quickly.

[0024] In addition, the material in the cylinder 1 is continuously flowing in and out, and no dead material will remain somewhere, so there will be no mixing dead corner.

[0025] The utility model does not need to overturn or rotate the cylinder 1, and the equipment has low power consumption and high safety.
