DEVICE FOR KEEPING SELECTIVE PLATE BEING HORIZONTALLY FOR PEANUT HAVESTING MACHINE

摘要

The present invention relates to a device for keeping horizontal a selecting plate (10), which has the shape of a sieve and is attached to a peanut harvesting the machine to shake the earth. The selecting plate (10) in the peanut harvesting machine is supported by a front axis (10) and a rear axis (13). An elongated hole (42) is formed on a support part (40) and receives the front axis (12) to be able to move in a certain interval. The fore-end part of the selecting plate (10) can be lifted or lowered as the rotating force of a motor rotates a first link (22) and a second link (24) moves together therewith. A horizontality sensor (110) can detect the state of the peanut harvesting machine and a potentiometer (30) can detect the rotating angle of the first link. A control part (100) rotates the first link by driving the motor (20) to correspond to the value of inclination detected by the horizontality sensor and controls the first link based on a value detected by the potentiometer. The selecting plate can be kept horizontal by compensating for the inclination of the peanut harvesting machine even if the peanut harvesting machine is inclined as the first link and the second link lifts or lowers one side of the selecting plate.
