Material feeding and uniformizing device for flour cleaning machine

Abstract

The invention discloses a material feeding and uniformizing device for a flour cleaning machine in the technical field of grain processing machinery. The material feeding and uniformizing device comprises a material feeding box, and a material feeding inlet is formed in the top of the material feeding box. A material receiving supporting plate is arranged on the lower side of the material feedinginlet and comprises a side wall and a bottom wall. The side wall is arranged on one side of the material feeding inlet, and the bottom wall guides materials to the other side of the material feeding inlet. An adjusting valve plate is arranged at the end of the bottom wall, and a circulating gap for material passing is reserved between the adjusting valve plate and the inner wall of the material feeding box. The adjusting valve plate comprises a flat plate connected with the bottom wall, and a cocked vertical plate. A plurality of valve plate overflowing holes are uniformly distributed in the break angle between the vertical plate and the flat plate along the arris of the break angle. An inclined material laying dripping plate is arranged on the lower side of the material receiving supporting plate, and a movable pressing plate is connected between the material receiving supporting plate and the material laying dripping plate. A uniform distribution plate is vertically arranged betweenthe lower end of the movable pressing plate and the lower end of the material laying dripping plate, and a bent L-shaped material distributing plate is hinged to the uniform distribution plate. According to the material feeding and uniformizing device, through two-time material uniformizing, it is ensured that the materials are uniform and flat.

Description

technical field [0001] The invention relates to the technical field of grain processing machinery, in particular to a feeding and leveling device for a powder cleaner. Background technique [0002] Powder cleaning machine is a kind of processing equipment in the field of grain processing machinery. It is used to purify and classify grain powder with different particle sizes, and to screen out grain powder with consistent particles and good quality. At present, the powder cleaning machine is fed through the feeding box. The material is automatically graded by vibration, wind and sieve. However, when the material is fed, because the position of the leveling door is not easy to adjust, the effect of leveling the material is poor if the gap is too large, and the material is easily blocked if the gap is too small. To solve this problem, The prior art discloses an invention, the application number is 201320667940.7, the authorized announcement number is CN 203565361 U, the authori...
