GRAIN SUPPLY CONTROLLER FOR OSCILLATION SCREENING TYPE RICE HULLING AND SCREENING MACHINE

摘要

PURPOSE: To simplify construction, to lower the height of a machine body and to reduce the size thereof by mounting a mixed rice hopper in a stationary state to the grain discharge port in the upper part of a grain lifting machine for lifting the mixed rice after air screening to a mixed rice screening section in an unhulled rice air screening section. ;CONSTITUTION: The rice hulling and screening machine consists of a rice hulling section for executing rice hulling, the unhulled rice air screening section for air screening the unhulled rice from the rice hulling section and the mixed rice screening section of an oscillation screening type for separating and screening the mixed rice after the air screening to rough rice and unpolished rice. The mixed rice after the air screening in the unhulled rice air screening section is lifted to the mixed rice screening section by the grain lifting machine 2. The grain lifting machine 2 is constituted to a bucket grain lifting type and a mixed rice hopper 14 is mounted in the stationary state to the grain discharge section 2a in the upper part of the grain lifting machine 2. The bottom of the hopper 14 is constituted of a downflow plate of an inverted truncated chevron pattern viewed laterally and the downflow plate on the side further from the grain lifting machine 2 is freely oscillatably supported to constitute a mixed rice supply control valve 30. This valve 30 is interlocked and connected to a rough rice supply control valve 29 for controlling the grain supply rate to the rice hulling section.;COPYRIGHT: (C)1994,JPO&Japio
