Description

Technical Field

[0001] The utility model relates to the field of feed towers, in particular to a conical feed tower for preventing feed accumulation. Background Art

[0002] The existing feed tower includes a cylinder and a lower cone, and the lower cone is below the cylinder and fixedly connected to the cylinder. The inner wall of the lower cone is a conical surface, so that the feed can slide down along the inner wall of the lower cone to the discharge port. The larger the angle between the inner wall of the lower cone and the horizontal plane, the easier it is for the feed to slide downward. However, if the angle between the inner wall of the lower cone and the horizontal plane is too large, the axial height of the lower cone will be too large. When the height of the feed tower is fixed, the lower cone occupies the height of the cylinder, resulting in less feed being accommodated inside the feed tower. If the angle between the inner wall of the lower cone and the horizontal plane is reduced, the axial height of the lower cone will be reduced, but an angle that is too small is not conducive to the feed sliding downward, and it is easy for the feed to accumulate on the inner wall of the lower cone. Utility Model Content

[0003] The utility model aims to solve the above problems and provides a feed accumulation-proof conical feed tower, which solves the problem that feed is easily accumulated on the inner wall of the lower cone of the feed tower.

[0004] A conical feed tower for preventing feed accumulation comprises: a cylinder and a lower cone, wherein the lower part of the cylinder is fixedly connected to the lower cone, a discharge port is formed at the lower part of the lower cone, the inner wall of the lower cone comprises a first conical surface and a revolving surface, the first conical surface and the revolving surface are coaxial, the revolving surface is located between the upper and lower first conical surfaces, the minimum diameter of the first conical surface above the revolving surface is greater than or equal to the maximum diameter of the first conical surface below the revolving surface, and the angle between the revolving surface and the horizontal plane is greater than the first angle between the generatrix of the first conical surface and the horizontal plane.

[0005] Furthermore, a transition surface is formed between the first conical surface and the revolving surface.

[0006] Furthermore, the transition surface is a rounded corner or a chamfered corner.

[0007] Furthermore, the rotation surface is a cylindrical surface.

[0008] Furthermore, a first included angle between the first cone surface generatrix and the horizontal plane is 60° to 72°.

[0009] Furthermore, the first angle is 67°.

[0010] Furthermore, the cylinder is formed with a feed port.

[0011] Furthermore, it also includes a feeding device, which is located below the lower cone and fixedly connected to the lower cone, and is communicated with the discharge port.

[0025] like Figures 1 to 5 As shown, a conical feed tower for preventing feed accumulation includes: a cylinder 1 and a lower cone 2, the lower part of the cylinder 1 is fixedly connected to the lower cone 2, a discharge port 20 is formed at the lower part of the lower cone 2, the inner wall of the lower cone 2 includes a first conical surface 21 and a rotating surface 22, the first conical surface 21 and the rotating surface 22 are coaxial, the rotating surface 22 is located between the upper and lower first conical surfaces 21, the minimum diameter of the first conical surface 21 above the rotating surface 22 is greater than or equal to the maximum diameter of the first conical surface 21 below the rotating surface 22, and the angle between the rotating surface 22 and the horizontal plane is greater than the first angle a between the generatrix of the first conical surface 21 and the horizontal plane.

[0026] Furthermore, a transition surface 23 is formed between the first conical surface 21 and the revolving surface 22 .

[0027] Furthermore, the transition surface 23 is a rounded or chamfered corner, which is used to eliminate the boundary line between the first conical surface 21 and the rotating surface 22, so that the feed moves more smoothly.

[0028] Furthermore, the revolving surface 22 is a cylindrical surface, that is, the angle between the revolving surface 22 and the horizontal plane is 90°.

[0029] Furthermore, a first included angle a between a generatrix of the first conical surface 21 and a horizontal plane is 60° to 72°.

[0030] Furthermore, the first angle a is 67°.

[0031] Furthermore, the cylinder 1 is formed with a feed port 10, and the feed port 10 is used to charge feed into the feed tower.

[0032] Furthermore, it also includes a feeding device 4, which is located below the lower cone 2 and fixedly connected to the lower cone 2, and is communicated with the discharge port 20. The feeding device 4 is a prior art.

[0033] Furthermore, it also includes a bracket 3, which is fixedly connected to the cylinder 1 and / or the lower cone 2.

[0034] Furthermore, the lower cone 2 is formed by splicing multiple steel plates.

[0035] Working principle:

[0036] The feed slides downward along the inner wall of the lower cone 2. The distance the feed slides on each first cone 21 is shorter than that of the monolithic cones of existing silos, making it less likely for the feed to stick to the first cone 21 during the sliding process. A vertical or nearly vertical rotating surface 22 is provided at the lower end of the first cone 21. This allows the feed to accelerate along the rotating surface 22 using gravity, allowing it to move more smoothly on the next first cone 21 and making it less likely to get stuck on the surface of the first cone 21.

[0037] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
