Inventor: KOBASHI TERUHISA
IPC: E02F3/40
Filed: 1984-04-19
Abstract: PURPOSE:To stabilize the operations of a bucket by a method in which the curvature of the tip side of a fork-like curved digging claw constituting the bucket is almost equalized with the radius of the bucket, and the curvature of the base end side is made smaller than the rotating radius of the bucket. CONSTITUTION:Many digging claws 28 are attached to the tip of a fitting base 27 pivotally supported on an arm 13 by a pin 16 to make up a bucket 15. The curvature XR of the tip side of the claw 28 is almost equalized with the rotary radius X of the bucket 15, and that YR of the basal end portion is made slightly smaller than the rotary radius X to form a relief angle. When the bucket 15 is turned and the claw 28 is cut into soil, the driving resistance of the tip side of the claw 28 is smaller and the turning of the tip side of the claw 28 in the deeper direction in the soil is interrupted. Since load on the rhizome root digger is reduced, the inclination of the digger forwards is inhibited, and the digging depth of the claws is nearly constant, the rhizome root can be taken by digging without causing damage to the rhizome.
