    • PURPOSE:To permit stable and smooth delivery and discarding operations of soil by a method in which a fitting frame is made up of left and right handed vertical bars and horizontal bars, the tip of the horizontal bar is pivotally attached to the bottom gravity position of a soil delivery rack, and the gravity center is moved and the delivery rack is inclined when loaded with soil. CONSTITUTION:A fitting frame 3 to be connected to rear of a tractor 1 is made up in an L-shaped form of left and right-handed vertical bars 6 and left and right-handed horizontal bars 7. The front bottom of a soil delivery rack 4 is placed on the horizontal bas 7, and their tips are pivotally attached to a given pivotal position 8 of the bottom of the rack 4 in such a way that the gravity center W is near the pivotal position 8 when soil 9 is not loaded and when loaded with soil 9 the gravity center W moves backwards and the rack 4 is tilted. Also, a coupling mechanism 10 is provided to keep it under placed condition. Since the tractor 1 is advanced while cutting the soil 9 and the coupling mechanism 10 is released at a desired position to discard the soil 9, stable and smooth operations for the delivery and discarding of soil can be performed.
    • 目的:为了通过左右立杆和水平杆构成的装置框架的方法使土壤稳定平稳地输送和丢弃操作,水平杆的尖端可枢转地附接到底部重力位置 土壤输送架,并且重心移动,并且在装载土壤时输送架倾斜。 构成:要连接到拖拉机1的后部的装配框架3以L形形式的左右垂直杆6和左右水平杆7制成。土壤输送的前底部 齿条4被放置在水平底座7上,并且它们的尖端可枢转地附接到齿条4的底部的给定的枢转位置8,使得当土壤9未被加载时重心W靠近枢转位置8 当装载土壤9时,重心W向后移动,并且齿条4倾斜。 此外,提供联接机构10以将其保持在放置状态。 由于拖拉机1在切割土壤9的同时前进,并且联结机构10在期望的位置被释放以丢弃土壤9,因此可以执行用于输送和废弃土壤的稳定和平稳的操作。
