The diffusing drop section was provided below the rubber belt deflection section at the front end of the belt conveyor so as to project to the right or left of the left edge or right edge of the belt conveyor, respectively, at right angles to the belt conveyor and horizontally. In addition, the floor soil diffusing drop section is suspended above the rubber belt turning section at the front end of the belt conveyor, and the floor soil diffusing drop section is placed above the lower opening of the floor soil receiving hopper. By fixing the central part and installing it horizontally below the belt conveyor in the front-rear direction, even if the rubber belt has a width that requires a small amount of power to convey, the floor soil falling from the front end of the belt conveyor. , And can be dropped by the screw auger respectively, so even with a paper cylinder with a large width developed on the soil filling device placed on the ground below the floor soil diffusing drop section, the floor can be Soil can be supplied uniformly, and a structure can be obtained that corresponds to the shape of the nursery ground and the type of the soil filling device, and a great effect can be obtained in labor saving of the work of supplying the floor soil to the soil filling device.

By increasing the floor soil supply hopper to the upper part so that the frame can be detached and attached, it is possible to easily increase the amount of floor soil to be accommodated, and to increase the open upper surface to use a bucket or the like of the front loader. It is possible to easily supply the bed soil to the bed soil supply hopper. Further, by manually providing a plurality of stirring rods penetrating the central portion of the bed soil supply hopper in the front and rear direction, it is possible to prevent the bed soil from being blocked in the bed soil supply hopper with a simple means.

Even if the floor soil supply hopper is full, the front loader is provided by arranging lifting girders in parallel with the left and right or front and rear in the lower part of the four-column frame body that supports the floor soil supply hopper on the ground. The unique effect is that the lift arm can be inserted into the lifting girder and the entire floor soil supply device can be lifted and moved.
