に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a rotary perforated cylinder with both ends open in the machine frame in an inclined manner, and inside the perforated cylinder, one end is connected to the machine frame and the other end is connected to the machine frame. A rotary shaft with a crushing rod supported on the arm is inserted, and the clod thrown into the porous cylinder rotating at low speed from the opening at the upper end of the slope is crushed by the high speed rotation of the crushing rod, and the crushed soil is transferred to the porous cylinder. The soil crusher is designed to sort and fall from the surrounding wall of the earth, and to discharge large foreign objects through the opening on the slanted lower end of the perforated cylinder.
In particular, the present invention relates to an improvement in the bearing structure on the inclined upper end side of the rotating shaft.

た。[Prior art and its problems] The conventional bearing structure on the inclined upper end side of the rotating shaft is as follows:
For example, as shown in Japanese Utility Model Publication No. 59-2840, open end face arms are stretched across the slanted upper end side of the perforated cylinder in a cross shape, and the slanted upper end of the rotating shaft is placed at the intersection center of the cross arms. Therefore, in such a structure, the space between the arms serves as the introduction port for the clod.
With this kind of structure, the cross-shaped arms rotate together with the perforated cylinder, which results in the arms blocking the input of the clod from entering the perforated cylinder.
Therefore, there is the disadvantage that the clod stagnates at the entrance of the perforated tube, reducing the crushing efficiency.Furthermore, the impact when the clot is crushed by the crushing rod is transmitted to the perforated tube via the arm. There was a problem of damaging the perforated cylinder and related interlocking mechanism.

As shown in the crusher of Publication No. 59-24364,
The inclined upper end of the rotating shaft whose inclined lower end is supported on the machine frame is supported on the wall surface of the hopper, and a screw conveyor is provided which forcibly conveys the clod put into the rotating shaft part in the hopper area in the direction of the perforated cylinder. It has been proposed that the tube be provided with a hole to smoothly supply the clod to the porous tube. According to this soil crusher, the problems of the soil crusher shown in the above-mentioned Japanese Utility Model Publication No. 59-2840 can be solved, but the crushing impact caused by the crushing rod is transmitted to the hopper via the rotating shaft, and this impact is further Since the width is increased and transmitted to the machine frame, in order to prevent this, it is necessary to make the hopper structure strong, and the connection structure between the hopper and the machine frame also needs to be devised. However, there are economic issues such as increased costs for soil crushers.

In order to facilitate the entry of clod into the porous cylinder,
It is also an attempt to rationally eliminate the adverse effects on porous cylinders and the like due to the impact of the crushed earth.
