TECHNICAL FIELD OF THE INVENTION
The present invention includes a self-propelled crusher equipped with a crushing device for crushing construction waste materials and the like, and a self-propelled soil improver equipped with a mixing device for crushing and mixing by adding a soil improving material to soil and the like. It relates to a self-propelled waste disposal machine.
[0002]
[Prior art]
The self-propelled crusher crushes waste such as construction waste such as concrete waste and rocks generated during the demolition of buildings and bridges. A crusher is mounted on the self-propelled bogie as a processing device. The construction waste material fed into the hopper arranged at the upper front is transported to the crusher by a feeder, crushed to a predetermined size by an engine driven crusher, and discharged from the lower crusher. . Then, as disclosed in, for example, JP-A-2000-325819, the crusher is arranged at the center of the machine body, and the engine is arranged horizontally in the vehicle body width direction and arranged behind the machine body. It was common to have a conveyor extending from the lower part of the crusher to the upper rear part via the lower part of the engine.
[0003]
The self-propelled soil improvement machine is for improving soil properties of excavated soil (so-called construction-generated soil) generated in civil engineering work, which is not suitable for backfilling, and reuses it. Sediment waste loaded on a trolley and placed in a hopper arranged in front of the trolley is conveyed to a mixing device by a feeder or a conveyor, and crushed and mixed with a soil improving material by an engine driven mixing device. It is configured to process and discharge from the lower part of the mixing device. The layout is such that, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2002-95991, the engine is disposed horizontally in the vehicle body width direction and disposed behind the machine body, and the conveyor extends from the lower part of the mixing device to the rear upper part. Was generally provided.
[0004]
[Problems to be solved by the invention]
By the way, in order to carry a self-propelled waste treatment machine into a site with limited working space and operate it without excess or shortage, the machine body must be as compact as possible and have stable running performance. You. However, when the engine is arranged behind the machine body as in the above-described conventional example of a self-propelled crusher, the hopper, the processing device, and the engine are arranged in series, so that the size of the machine body in the front-rear direction becomes longer and the center of gravity is increased. Is behind the trolley, so a slow movement is required for stable running. In addition, if the engine is to be arranged behind the machine body, interference with the conveyor must be avoided. As a result, the position of the center of gravity of the engine is increased and stability is lacking. Further, in such a case, there is a problem that the rear surface of the crusher is closed by the engine, and maintenance of the crusher becomes difficult. On the other hand, also in the conventional self-propelled soil improvement machine, since the engine is arranged at a high position behind the machine body, the center of gravity of the engine becomes high as a result, resulting in lack of stability.
[0005]
As a technique for solving such problems, the applicant has disclosed in Japanese Patent Application No. 2001-379162 a crushing device, a power source for driving the crushing device, and a material to be crushed by the crushing device. A hopper, a feeder that conveys the material to be crushed into the hopper toward the crushing device, and a self-propelled vehicle on which these are mounted. And a hopper are arranged side by side, and a crusher is arranged on the other side.
[0006]
According to the present invention, since the power source and the hopper are arranged side by side on the opposite side of the crushing device having the heaviest weight, compactness and stable weight balance can be achieved. Then, from the viewpoint of installation space and maintainability, the fuel tank of the engine, which is the power source, is disposed below the hopper slide plate on the counter power source side with the hopper interposed therebetween.
[0007]
However, when this arrangement is adopted, the fuel tank is a substantially rectangular parallelepiped, the upper surface of which is flat, and the fuel supply port is also provided. They may hit the fuel supply nozzles and damage them. In addition, extra work to remove the accumulated crushed material each time fuel is supplied when the crushed material accumulates on the upper surface of the tank increases, and accumulated dust and the like are mixed in at the time of supplying the fuel, thereby shortening the life of the fuel filter. There was a problem that said it was extremely short.
[0008]
Such a problem occurs in the self-propelled soil improvement machine as long as the hopper and the power source are arranged side by side.
[0009]
The present invention has been made in view of the above problems, and an object of the present invention is to provide a self-propelled waste disposal machine including a fuel tank that prevents damage caused by an object to be spilled from a hopper.

Most of them scatter outside the self-propelled bogie along the slide plate of the hopper. Even if a part of the tank falls on the upper surface of the tank, the upper surface of the tank is inclined outward and downward, so that it falls and scatters outside the self-propelled vehicle as described above. Therefore, it is possible to prevent a part of the processing object from dropping and colliding with the upper surface of the tank, and further, the processing object does not accumulate on the tank.
[0012]
The means adopted by the self-propelled waste treatment machine according to claim 2 of the present invention is the self-propelled waste treatment machine according to claim 1, wherein a fuel supply port is provided at one side of the fuel tank. The gist is that a guard plate portion for guarding the fuel supply port extends along the upper surface of the fuel tank.
[0013]
According to the self-propelled waste treatment machine according to the second aspect, the fuel supply port is guarded from the object to be dropped, so that the base of the fuel supply port is not damaged and dust and the like are not damaged. Since accumulation is also prevented, dust and the like are less likely to be mixed into the fuel during fuel supply, and the life of the fuel filter can be extended.
