Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a rice ejecting device for a vertical shaft type circulating rice mill.

[Prior art and its problems]

In the conventional vertical shaft circulation type rice mill, a spiral transport trochanter is arranged vertically at the center of the mortar, and this transport trochanter rotates to transport the rice grains in the mortar downward along the spiral grooves of the trochanter. The rice grains are polished by frictional force in the space between the lower part of the transport trochanter and the bottom of the mortar (the milling chamber), and then rise and circulate along the inner wall of the mortar.
It is something to be refined. The rice discharging device is provided with a rice discharging port on the lower side of the mortar-shaped container, and a valve plate made of a single plate is attached to the rice discharging port from the outside of the mortar-shaped container so as to extend along the peripheral wall surface. Methods have been implemented in which the rice discharge port is opened and closed by moving or pivoting one edge of the valve plate in a direction perpendicular to the surrounding wall surface, but the pressure in the polishing chamber where the rice grains are friction polished is may be bent or detached from the valve plate, resulting in malfunction, or uneven circulation may occur due to the step between the inner wall surface and the valve body, and the polished rice to be discharged may directly come from the container wall surface. It has the disadvantage that it flies forward and scatters around, impeding work efficiency.

In view of the above-mentioned drawbacks, the present invention provides a rice discharge valve of a unique structure in the rice discharge port provided on the conical plate with a porous wall for removing bran on the lower side of the mortar-shaped container, thereby eliminating the curvature of the valve plate or the rice discharge valve having a unique structure. A high-performance vertical shaft type that completely prevents rice grains from separating, eliminates uneven rice grains, and eliminates the problem of rice grains scattering directly forward from the container surface.It is safe and robust, and also simplifies rice removal work. The purpose is to provide a rice ejecting device for a circulating rice mill.

[Means for solving problems]

In order to solve the above problems, the present invention provides a conical wall with a porous wall for removing bran at the bottom of a mortar-shaped container, and
A transport trochanter is inserted into a vertical shaft erected in the center of the porous wall conical disc for rice bran removal, and a vertical shaft is formed in the whitening chamber between the lower part of the transport trochanter and the porous wall conical disc for rice bran removal. In the shaft-type circulation rice milling machine, a rice discharge port having a circular projection plane parallel to the vertical axis is provided on the inclined peripheral wall surface of the porous wall conical disk for bran removal provided at the bottom of the mortar-shaped container; A rice discharging valve consisting of a cylindrical body equipped with a valve plate having an inclined wall surface that is substantially the same shape as the rice discharging opening notch in the wall surface is rotatably fitted into the rice discharging opening on an axis substantially perpendicular to the vertical axis. , as a means of problem solving.

[Effect]

Rice grains placed in a mortar-shaped container are sent downward by a transport trochanter that rotates together with a vertical shaft installed in the center, are milled while being stirred in the milling room, and are swung outward into the mortar shape. It flows upstream along the inclined inner wall surface of the container, reaches the center of the mortar-shaped container again, and is sent downward by a transport trochanter to be refined. When the rice grains reach a desired degree of polishing after undergoing multiple polishing operations, the rice discharge valve is rotated to discharge the polished rice in the mortar-shaped container to the outside.

Reference numeral 9 denotes a rotation mechanism provided on the base 10, and the rotation mechanism 9 and the vertical shaft 3 are connected and rotated. Reference numeral 11 denotes a resistance ring provided between the inner circumferential wall of the mortar-shaped container 1 and the circumferential wall of the transportation trochanter 5, and 12 denotes an adjustment support shaft rotatably erected at the upper end of the transportation trochanter 5.

Reference numeral 15 denotes a fixed outer cylinder provided on the outer periphery of the porous-walled conical disc 2 for bran removal, 16 refers to a bran removal path inside the fixed outer cylinder 15, 17 refers to a bearing portion that supports the vertical shaft 3, and 18 refers to a bran removal chamber 7. The contacted rice bran container, 19, is rice bran container 1.

1 so as to be rotatable and fixed with a mounting bracket 27. When the rice discharge valve 21 is rotated to make the inclined wall surface of the valve plate reversely inclined, the rice grains are configured to flow down and be discharged from a gap B opened outside the lower end of the rice discharge port 21. Reference numeral 25 is a rice ejecting gutter provided on the fixed outer cylinder 15, and 26 is a rotating operating rod provided on the rice ejecting valve 24.

It flows upstream along the inner circumferential wall of the container 1, descends again from the center of the mortar-shaped container 1 by the transport trochanter 5, and is pumped. At this time, the flow of the grains flowing upstream along the inner peripheral wall of the mortar-shaped container 1 is suppressed by the resistance ring 11, so the frictional force between the rice grains, the porous-walled conical disc for removing bran 2, and the rice grains increases. This ensures efficient whitening action. In addition, the rice bran powder generated by the whitening action is removed from the through holes of the porous wall conical disk 2 for rice bran removal by the suction force of the rice bran scraping impeller 6 and the exhaust fan 19 provided on the base 10. The bran is absorbed into the bran chamber 7, and the bran-containing air flows into the bran collection container 18. The air from which the bran powder has been separated by the bran removing filter is then transported to the base 10.
be ejected from the aircraft via the inside. When discharging polished white rice from the mortar-shaped container 1, when the rotary operation rod 26 provided on the rice discharge valve 24 is rotated, the inclined wall surface of the valve plate 22 is tilted in the opposite direction, and the rice discharge port 21 is disposed of. A gap B is formed outside the lower end, and the white rice in the container 1 flows down from the gap B to the lower rice discharging gutter 25, and is taken out of the machine by sliding on the gutter surface.

The rice discharging valve is installed so as not to create a level difference with the inclined peripheral wall surface, and when the rice discharging valve is rotated, the inclined wall surface of the valve plate becomes reversely inclined, and the lower part of the rice discharging port opens. Uniform circulation eliminates milling spots, and there is no curvature of the valve plate 22 due to the pressure in the milling chamber, making it possible to smooth the flow of rice grains and ensure normal milling action, and completely eliminate malfunctions caused by separation of the valve plate. It is safe and robust, and also has the effect of simplifying the rice dumping operation without causing rice grains to get caught.
