To provide a self-propelling soil improving machine improvement material hopper and a self-propelling soil improving machine capable of maintaining a constant supply amount of improvement material, reducing rotational driving power and curtailing a working cost when materials are conveyed.
An improvement material supply device 20 internally provides a revolutional body 40 consisting of an outer rim member 41, an inner rim member 42 and a feeder blade 43 to a case 21 mounted to the lower part of an improvement material hopper 10 through a bearing 44 in a rotatable manner. Then, a window 30 coated with an openable cover 31 is provided in an upper plate 27 upward of an improvement material outlet 23 provided in the bottom plate 22 of the case 21. A lower edge 14 of the improvement material hopper 10 is located inward from the internal circumferential surface 46 of the outer rim member 41 of the revolutional body 40 and downward from the upper end face 47 of the outer rim member 41. The improvement material hopper 10 is mounted in a detachable manner and, at the same time, the height is lower than the height from the lower end face of a travelling body 2 to the lower end face of a soil conveying device 6.
