WEEDING APPARATUS FOR CULTIVATED RICE SEEDLING THROUGH UTILIZING SULKY RICE TRANSPLANTER

摘要

PROBLEM TO BE SOLVED: To provide a weeding apparatus for cultivated rice seedlings, capable of effectively conducting operations such as weeding and leveling by dragging chains suspended from a traversing frame for giving reciprocating motion in a longitudinal direction. ;SOLUTION: When horizontally bearing a power input shaft 4 near to the center of a lengthy frame body 3 having side frames 2 for supporting square thrust bearing 1 in both ends of the body 3, fixing a crank arm 6 having plural regulating holes 5 in the rear end of the shaft 4, slidably inserting into the bearing 1 of the side frame 2 square shaft part 10 in both sides of a traversing frame 9 parallel fixing and supporting a frame 8 from which chains are suspended and in which many holes 7 for holding chains at a preferred interval of distance, coupling the output lever 11 fixed in the center of the frame 9 with the crank arm 6 through a coupling rod 12 adjustable in terms of its length and suspending many chains 13 in a U-shaped state from the holes 7 of the frame 8, weeds among rice seedlings in being cultivated are removed by the chains 13 of the frame 9 traversing in a longitudinal direction owing to the power from the input shaft 4.;COPYRIGHT: (C)2000,JPO
