[0022] The material is placed on the feeding vibration mechanism 2, and the feeding vibration mechanism 2 preliminarily breaks up the material and transfers it to the feeding climbing conveying mechanism 3. The feeding climbing conveying mechanism 3 transfers the material from a low place to a high place and transfers the material to the vibration feeding mechanism 4.
