く円滑な作業が行える。As explained above, the present invention is based on a multi-continuous subsoil structure in which two or more shanks each having an excavating tool such as a chisel attached to the lower end are arranged in parallel in the width direction, and each shank is operated at a different phase from each other. In the crushing device, each of the shanks described above is attached to a junk bracket that swings around a swing fulcrum shaft, one end of a crank rod is connected to each shank bracket, and a bearing 23 is connected to the other end of the crank rod. It is connected to the camshaft 17 through the
The shank bracket is oscillated back and forth by the camshaft and crank rod to vibrate each shank, and the camshaft is interlocked and connected to the connecting shaft cylinder 19 via the spline shaft joint 18, and the spline shaft joint is rotated in the direction of rotation. Since the extension angle of each shank can be changed and adjusted by shifting and replacing them, subsoil crushing and underdrain formation can be performed at multiple locations at once, which significantly improves work efficiency. It is possible to effectively eliminate vibrations caused by shank rocking, thereby preventing negative effects and discomfort on the machine itself and the operator, especially when using a spline shaft joint under different field conditions. By shifting the position in the rotational direction and replacing it, it is possible to adjust the phase shift to suit the field conditions and effectively eliminate vibrations, allowing operators to work smoothly without causing vibrations at all times.
