CORNER SOIL CLEANUP MACHINE FOR SEEDING BOX

摘要

PROBLEM TO BE SOLVED: To provide the subject machine designed to smoothly and properly conduct a cleanup of extra soil left along the rear wall side of the advance side after carriage of a seeding box. ;SOLUTION: This machine has such a scheme that each one end of left and right swing arms 5 swinging vertically with a support 2 on the transverse identical axial line inside a corner soil cleanup machine C is mutually connected so as to be integratedly swingable and a soil pressing section 6 with flat underside is set up perpendicularly, while the other ends are connected to a solenoid SL so as to ensure the soil on the rear wall 2b side to be leveled through the downward and upward motions of the soil pressing section 6; a detective switch LSA detecting the rear wall 2b of a seeding box and a lower limit switch LSB detecting the time of the most downward motion of the soil pressing section 6 are also connected to the solenoid SL; furthermore, it is preferable that a timer is interposed between the detective switch LSA and the solenoid SL so that, within a given time, even if the detective switch LSA turns ON, the solenoid SL ignores the event.;COPYRIGHT: (C)1999,JPO
