摘要

PROBLEM TO BE SOLVED: To provide a working machine for burying materials and its construction method in which a farmer creates an agricultural land with high productivity by a self-owned tractor simply and quickly.SOLUTION: A working machine for burying materials includes: a soil block lifting unit 20 for forming a predetermined cavity in the soil by cutting and lifting a trapezoidal cross-section soil block with an upper base longer than a lower base and having a vertical leg and an inclined leg; and a material feeding unit for feeding the materials into the formed cavity. An L-shaped cross-section cavity C comprising a side cavity A and a bottom cavity B is formed in the soil by being lifted using a soil block 31, a soil block lifting plate 20E and a side surface keep plate 20D, and the materials gathered by a material collector 11 and a material collecting feeder 21 are fed and dropped into the cavity C. When a pipe laying unit is included, the materials are fed after laying the pipe in the lowermost part of the side cavity A.SELECTED DRAWING: Figure 1
