MUD-REMOVING PART STRUCTURE OF CROP SEEDLING HARVESTER

摘要

PURPOSE: To obtain a mud-removing structure having more effective mudremoving function without causing the unnecessary lateral swinging motion of the seedling and exhibiting excellent performance such as the removal of mud from a part unable to clean by conventional method, decreased damage on the root and sure mud-removing work by providing a pair of right and left mudremoving claws and reciprocating the claws opposite to each other perpendicular to the transfer direction to effect the removal of mud. ;CONSTITUTION: This mud-removing structure is provided with a clamping and hoisting apparatus to transfer a dug-up seedling upward to the back in suspended state and a mud-removing transfer apparatus acting on the root of the seedling to apply a transfer force while removing the mud from the root. The mud-removing transfer apparatus 3 has a number of mud-removing claws 18 to be thrust into the root and attached to a circulating chain 19 in laterally movable state. The mud-removing claws 18 are oscillated by an oscillation driving mechanism 3B. The mud-removing transfer apparatus 3 is inclined to raise the back relative to the transfer belt 2B to increase the thrusting depth of the claw 18 into the root in the direction of the stalk toward the downstream side of the seedling transfer direction.;COPYRIGHT: (C)1996,JPO
