  • Publication number: 20240173722
    Abstract: A mixing system includes a soil mixing device that crushes and grinds construction generated soil and a feed belt conveyor that is engaged with the soil mixing device and conveys the construction generated soil to the soil mixing device. In the feed belt conveyor, the number of degrees of freedom regarding rotation of a cylindrical member engaged with the soil mixing device differs from the number of degrees of freedom regarding rotation of a spherical bearing mechanism abutting on the ground. This configuration allows a plurality of units to be easily installed in an appropriate positional relation at a construction site or the like.
