[0001]

BACKGROUND OF THE INVENTION The present invention relates to a milling chamber for milling while transporting grains supplied to a receiving port by a feeding means to a discharge port.
A porous member provided with a hole for discharging the bran separated from the grain by the grinding in the grinding room to the outside of the grinding room is provided, and the bran removing cylinder has its longitudinal direction directed to the flow direction of the grain. In this state, a grain is detachably attached to the base at one end thereof, and a discharge unit for detaching a grain from the discharge port is detachably attached to the other end of the bran removing tube. Related to the device.

[0002]

2. Description of the Related Art Conventionally, in such a grain mill, only one end of both ends in a longitudinal direction of a bran removing tube is conventionally provided.
It has been configured such that it can be detachably attached to the base, and the discharge unit can be detachably attached only to the other end. Hereinafter, in the bran removing tube, the end to be attached to the base is referred to as an end on the base attachment side, and the end to which the discharge unit is attached is referred to as an end on the discharge unit attachment side.

[0003]

By the way, in such a grain milling device, the porous member provided on the bran removing tube wears first from a portion corresponding to the receiving port side in the grain flow direction, and the milling capacity is increased. Decrease. Therefore, for example, based on the operation continuation time of the grain mill, when the operation continuation time reaches the set time, the work of reversing the direction of the porous member in the flow direction to the milling room is performed, and the milling ability is restored. I was trying to make it. In a conventional apparatus, the operation of reversing the direction of the porous member in the flow direction with respect to the milling chamber has been performed as follows. In other words, the discharge unit is removed from the end of the bran removing cylinder on the discharge unit mounting side, and the end of the bran removing tube on the base mounting side is removed from the base. And once the porous member,
After being removed from the bran removing tube, it is attached to the bran removing tube again in a state where the direction of the porous member is reversed in the flow direction. Then, the end of the bran removing cylinder on the substrate mounting side is attached to the substrate, and the discharge unit is mounted on the discharge unit mounting side end. Therefore, conventionally, as an operation of reversing the direction of the porous member in the flow direction with respect to the milling chamber, the porous member is once removed from the bran removing cylinder, and the direction of the porous member is reversed in the flow direction. Then, it must be attached to the bran removing cylinder again, and the operation is complicated, and improvement has been desired. Incidentally, in such a grain mill, a plurality of grinding wheels are dispersedly arranged in the circumferential direction at intervals from one another in the bran tube, and a porous member is usually provided between each adjacent grinding wheel. In some cases, the work of removing and attaching a plurality of porous members to and from the bran removing tube was very complicated.

[0004] The present invention has been made in view of such circumstances, and its purpose is to restore the milling ability.
An object of the present invention is to simplify an operation of reversing the direction of a porous member in a direction in which grains flow in a milling room.

This allows the porous member to
The bran removing tube held in between and configured as described above can be attached to the base even in a state where it is inverted in its longitudinal direction, and the bran removing cylinder attached to the base in such a state where it is inverted in the longitudinal direction. A discharge section can be attached to the end of the tube.
By inverting the rice bran cylinder in its longitudinal direction, the porous member can be inverted in the direction in which the grains flow. Therefore, the operation of removing and attaching the porous member to the bran removing tube, which was conventionally required, becomes unnecessary, so that the direction of the porous member is reversed in the flow direction of the grain with respect to the milling room to restore the milling ability. The work to be performed can be simplified.

[0006] Further, even in an inverted state of the bran removing cylinder in its longitudinal direction, with respect to a plurality of bolt insertion holes located on the base side in the longitudinal direction of the bran-removing cylinder, a plurality of bolts can be inserted which is provided on the substrate In addition, a plurality of bolts provided in the discharge unit can be inserted into a plurality of bolt insertion holes located on the discharge unit side in the longitudinal direction of the bran removing cylinder. Then, if a nut is screwed onto each bolt, it can be attached to the base in a state where the bran removing tube is inverted in the longitudinal direction. A discharge section can be attached to the end of the tube. Therefore, even in a state where the pair of bran removing tube side mounting portions, the base body side mounting portion, and the discharge portion side mounting portion are arranged with the pair of bran removing tube side mounting portions inverted in the longitudinal direction of the bran removing tube. As a specific configuration to be configured to be attachable to each other, a plurality of bolt insertion holes forming a bran removing tube side mounting portion, a plurality of bolts forming a base side mounting portion, and a plurality of forming a discharge portion side mounting portion. Can be realized with a simple configuration in which the bolts are arranged in a predetermined arrangement relationship, so that the cost for implementing the present invention can be reduced.
