PADDY FIELD GRADER FOR TRUCTOR

摘要

PURPOSE:To incline a paddy field grader backwards under own weight by a method in which the slightly forward point from the center of the bottom of a bucket is pivotally supported at the tip end of the horizontal lever of a fitting frame connected through a three-point link to the rear of a tructor in such a way that the gravity in the soil-loaded state is moved backwards from the pivotal supporting point. CONSTITUTION:A fitting frame 3 of a L-side view form is connected in a vertically rocking manner through a three-point link to the rear of a tructor 1. The bottom of a bucket 4 of a right-angular triangle side-view form is pivotally attached to the tip 8 of the L-shaped horizontal lever 7 of the fitting frame 3, and the tip of the vertical lever 6 of the fitting frame 3 and the tip of the front wall 13 of the bucket 4 are provided with a releasing coupling mechanism 10. A plow 5 provided slantly to the advancing direction of the tructor 1 is provided to the fitting frame 3, and soil excavated by advancing the tructor 1 is put into the bucket 4 from the opening of the front wall 13 of the bucket 4. The gravity position of the bucket 4 is moved backwards from the pivotal supporting point 8 by soil loaded on the bucket 4 and the bucket 4 is tilted under its own weight.
