Abstract

A bran removing wire-mesh tube includes: bran removing wire-mesh tube parts 28 divided in more than one in a circumferential direction in planar view; and a plurality of support pillars 33 erected at intervals in the circumferential direction to respectively fix both side edges of the divided bran removing wire-mesh tube parts 28 . Each of the support pillars 33 is provided with an elongated resistor 34 that suppresses grains from moving in the circumferential direction along with rotation of grinding type grain cleaning rolls 26 . The resistor 34 is urged by an elastic member 37 to a position at which the resistor 34 protrudes toward the inside of a grain cleaning chamber 30 . Further, the resistor 34 is provided so as to be movable in a radial direction to a position farther from the grain cleaning chamber 30 due to resistance from the grains.

First claim

The invention claimed is:

1. A grinding type vertical grain polishing machine comprising:
a bran removing wire-mesh tube erected in a top-bottom direction;
a main shaft rotatably provided inside of the bran removing wire-mesh tube;
a grinding type grain cleaning roll member integrally including multiple grinding type grain cleaning rolls axially supported by the main shaft;
a grain cleaning chamber formed between the bran removing wire-mesh tube and the grinding type grain cleaning roll member; and
a bran removing chamber and a resistor apparatus each formed on an outer circumferential side of the bran removing wire-mesh tube, wherein
the resistor apparatus includes: a plurality of support pillars erected around the bran removing wire-mesh tube; and a resistor and an urging apparatus provided for each of the support pillars,
the resistor has a leading end surface that approaches an outer circumferential surface of the grinding type grain cleaning roll member inside of the grain cleaning chamber, to thereby impart a resistance for suppressing movement to grains moving along with rotation of the grinding type grain cleaning roll member,
a position of the leading end surface is adjustable so as to be closer to or farther from the outer circumferential surface of the grinding type grain cleaning roll member in a radial direction of the grinding type grain cleaning roll member,
the resistor is always urged by the urging apparatus toward the grinding type grain cleaning roll member, and
when pressing force of the grains exceeds the urging by the urging apparatus, the resistor is retracted from the grinding type grain cleaning roll member against the urging,
wherein the urging apparatus is an air actuator, and includes an air cylinder and a pressure adjusting apparatus, wherein one end of the air cylinder is turnably attached to the pressure adjusting apparatus and urging by the urging apparatus is achieved by air pressure exerted by the air actuator wherein the resistor is formed such that one end edge thereof extending in an axial direction and each of the support pillars are supported by a hinge, while another end edge thereof is interlocked with the urging apparatus so as to be turn able about the hinge.

2. The grinding type vertical grain polishing machine according to claim 1 , wherein
the bran removing wire-mesh tube is configured as bran removing wire-mesh tube parts that are divided in more than one in a circumferential direction in planar view, and
the plurality of support pillars of the resistor apparatus are erected at intervals in the circumferential direction in order to respectively fix both side edges of the bran removing wire-mesh tube parts divided in more than one.

3. The grinding type vertical grain polishing machine according to claim 1 , wherein
the resistor is formed so as to have an elongated shape long in an axial direction of the grinding type grain cleaning roll member.

4. The grinding type vertical grain polishing machine according to claim 1 , wherein, in order to adjust urging force of the resistor at a position at which the resistor protrudes toward an inside of the grain cleaning chamber, each of the support pillars is provided with a resistor apparatus that makes the urging force adjustable by a turn position of a pressure adjusting dial.

5. The grinding type vertical grain polishing machine according to claim 1 , wherein
each of the support pillars is provided with an external air take-in port and an air jet port,
the air jet port is placed on a downstream side of the resistor of the resistor apparatus with respect to a flow of the grains and at a portion close to the resistor, and
air is jetted from the air jet port toward the grain cleaning chamber.

6. The grinding type vertical grain polishing machine according to claim 1 , wherein the urging by the urging apparatus is achieved by an elastic member.

7. The grinding type vertical grain polishing machine according to claim 1 , wherein the urging by the urging apparatus is achieved by an air pressure.
