Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

The embodiment of the utility model provides a:

as shown in fig. 1-5, the special-shaped cylinder feeder comprises a body, the body comprises a cylinder 1 and a conveying mechanism axially arranged in the cylinder 1 along the cylinder 1, a feeding port 2 is arranged at the upper side of one end of the body, and a discharging port 11 is arranged at the lower side of the other end of the body.

The cylinder 1 is a special-shaped cylinder, not a circular cylinder. The cylinder 1 includes a semicircular casing 13 at a lower half part and a rectangular casing 12 at an upper half part. The rectangular shell is a U-shaped shell with a rectangular cross section and a downward opening, and the semicircular shell and the rectangular shell are oppositely arranged to form a hollow cylinder structure.
