Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cereal which selectively removes non-regulated grains such as fine grains and defective grains mixed from selected grains such as brown rice crushed by a huller or polished rice polished by a rice mill. It relates to a sorting device.

[0002]

2. Description of the Related Art A cereal sorting apparatus comprising a porous sorting rotary cylinder provided in an exterior body of an airframe for sorting and removing irregular grains such as fine grains and defective grains from grains to be sorted such as brown rice or polished rice. There is a cylindrical grain sorter (rice grader). Conventionally, many rice graders have a configuration in which an electric motor for rotating and driving a perforated sorting rotary cylinder is attached to the outside of the body exterior body.

[0003] By the way, as in many conventional rice graders in which an electric motor is attached to the exterior of the body exterior body, there is naturally a limit to the miniaturization of the body, and the demand of the demand class can be sufficiently satisfied. The fact was not.

Therefore, the present applicant has previously proposed a cereal sorting machine in which a motor for rotating and driving a multi-hole sorting rotary cylinder is disposed in a multi-hole sorting rotary cylinder which forms a cavity (dead space) inside a body exterior body. As a result of the proposal of the device, a motor is not attached to the exterior of the fuselage body, and the size of the fuselage is greatly reduced (see Japanese Patent Application Laid-Open No. 10-272422).

[0005]

In this kind of cereal sorting apparatus, since the inside of the perforated rotary cylinder becomes a dead space except for the portion along the perforated sorting surface when viewed from the cereal sorting surface, the above-described cereal sorting rotary cylinder has a dead space. As described in Japanese Patent Application Laid-Open No. 10-272422, arranging the electric motor housing in the perforated sorting rotary cylinder is significant from the standpoint of greatly reducing the size of the apparatus.

[0006] However, the grains to be sorted rise and fall along the inner surface of the perforated sorting surface in the perforated sorting rotary cylinder. It is necessary to adopt a configuration in which it flows down, and the surface of the motor storage housing from which the output shaft of the motor is exposed forms the bearing of the output shaft of the motor, so grains (particularly white rice from which grain oil has oozed out) However, it was found that, when repeatedly contacting the part, the grain oil penetrated the bearing surface, causing a phenomenon in which the bran adhered to the bearing surface and solidified, resulting in rotation failure and an impossible situation.

[0007] In order to solve the above problems, the present invention provides an eaves portion by projecting the top surface of a motor storage housing disposed in a perforated sorting rotary cylinder toward an output shaft side of the motor, thereby providing a motor storage housing. Prevents the grains falling from above from accumulating on the top surface, and prevents the grains from falling on the bearing on the surface where the output shaft of the motor projects from the motor storage housing, so that the output shaft of the motor It is an object of the present invention to provide a cereal sorting apparatus capable of preventing rotation failure or inability to occur due to penetration and solidification of cereal oil in a bearing portion of the cereal.

[0008]

According to a first aspect of the present invention, there is provided a cereal sorting apparatus for selectively removing non-regulated grains such as fine grains and defective grains from selected grains such as brown rice or polished rice. A grain sorting apparatus comprising a cylinder provided in an exterior body of an aircraft, wherein a motor storage housing containing an electric motor for rotating and driving a perforated sorting rotary cylinder is fixed to one end of the exterior body of the body, and disposed in the exterior body of the body. A receiving roll for rotatably supporting the outer peripheral surface on one end side of the perforated sorting rotary cylinder is provided at one end side of the motor housing in the outer case where the motor storage casing is fixed, and the perforated sorting rotary cylinder is inserted so as to cover the motor storage casing. The outer peripheral surface of one end of the rotary cylinder is rotatably supported by a receiving roll, and the other end of the rotary shaft of the porous sorting rotary cylinder is connected to the output shaft of the motor so that the rotary rotary body is driven to rotate by the motor. And the other end side shaft center Become axially supported by a shaft provided in Sokarada, it is characterized in that it has a visor portion protrudes a top surface of the motor collection 筺 the output shaft side of the electric motor.

According to a second aspect of the present invention, there is provided a cereal sorting apparatus according to the first aspect, wherein a top surface of the electric motor storage casing forms a mountain-shaped inclined surface, and an eaves formed by projecting the top surface. The portion also forms a mountain-shaped inclined surface.
