DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a self-propelled crushing machine for crushing materials ("the object of crush") such as a concrete waste and so forth at a site of taking down a building or so forth.
BACKGROUND ART
As conventional self-propelled crushing machine, there has been known the machine, in which an operator's cabin, a hopper, a crusher and a driving power source and so forth are mounted on a vehicular chassis provided with a pair of left and right traveling bodies, and a discharge conveyer is provided beneath the vehicular chassis in risible fashion, as disclosed in Japanese Unexamined Utility Model Publication No. 64-32744.
These self-propelled crushing machines can travel by themselves and can finely crush the object of crush, such as the concrete wastes and so forth charged in the hopper, and discharge the crushed pieces out of the vehicular chassis through the discharge conveyer.
Such a conventional self-propelling crushing machine is charged with the object of crush and directly feeds the object of crush into the crusher from the hopper by dropping. Therefore, the object of crush falls along the hopper by its own weight. This results in fluctuation of feed amount of the object of crush into the crusher per a unit period depending upon the weight of the object of crush or charge amount of the object of crush into the hopper to make it impossible for the crusher to operate stably. Furthermore, blocking of the object of crush in the hopper may cause difficulty in feeding the object of crush into the crusher.
Therefore, it is an object of the present invention to provide a self-propelling crushing machine which can feed a substantially constant amount of object of crush into a crusher even when the weight of the object of crush or the charge amount of the object of crush into the hopper fluctuate, to thereby permit stable crushing operation of the crusher, and avoid the possibility of blockage of the object of crush within a hopper.
DISCLOSURE OF THE INVENTION
In order to accomplish the above-mentioned and other objects, according to one aspect of the invention, a self-propelling crushing machine constructed by mounting a hopper and a crusher connected to said hopper on a vehicle body having a traveling device, is characterized in that
a bottom plate of said hopper is designed for reciprocal motion in a horizontal direction relative to a charge inlet of said crusher.
With the construction set forth above, the bottom plate of the hopper receives the object of crush and then feeds it into the charge inlet of the crusher by reciprocal motion. As a result, a substantially constant amount of the object of crush may be fed into the crusher per a unit period, even when the weight of the object of crush or the charge amount thereof fed into the hopper fluctuates. Accordingly, stable crushing operation can be performed by the crusher. Also, the hopper may not be blocked by the object of crush.
In the construction set forth above, it is preferred that said bottom plate of said hopper and a circular plate rotatingly driven by a motor are connected to each other by a link for reciprocally driving said bottom plate by rotation of said circular plate.
With the construction set forth above, a discharge conveyer is disposed between said left and right pair of traveling mechanisms.
Also, said discharge conveyer is tiltable.
