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...

[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 authorized announcement date is 2014.04.30, and the patent name is a powder cleaning machine, including a frame and a chassis. There is a vibrating motor, and a feeding port and a leveling box are arranged above the vibrating motor, and a right-angled groove and a trip plate are arranged in the said leveling box, and a connecting plate armor is fixed on the right-angled groove, and the connecting plate armor is connected to the The connecting plate is hinged, and the end of the connecting plate B is provided with a wavy line leveling door, and an eccentric limit adjustment device is provided under the connecting plate B; the connecting plate B is provided with hollow holes, and the optimal number of the hollow holes is 3. The shape of the hollow hole is rectangular

Although the existing technology solves the problem that the leveling door is not easy to adjust, the position of the leveling door is adjusted by setting an eccentric limit adjustment device to improve the leveling effect and avoid material blocking; however, after the material enters from the feed port, it passes through the connecting plate A is easy to rush into the sliding plate, so that the material on the sliding plate accumulates, and a large amount of material directly overflows from the hollow hole of the connecting plate B and enters the screen surface, which does not achieve a good leveling effect. There is a line-to-surface contact between the material door and the material, which cannot quickly flatten the material, and the material leveling effect is poor, resulting in uneven material feeding, material deviation, etc., affecting production efficiency
