[Problems to be solved by the invention]
By the way, in order to carry a self-propelled waste disposal machine into a site with limited work space and operate it without excess or deficiency, the machine body is required to be as compact as possible and to have stable running performance. The However, when the engine is arranged behind the machine body as in the conventional self-propelled crusher, the dimensions of the machine body in the front-rear direction become longer as the hopper, processing device and engine are arranged in series, and the center of gravity Is behind the carriage, it is forced to move slowly 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 becomes high and stability is lost. Furthermore, in such a case, there is a problem that the rear surface of the crusher is blocked with an engine, and it becomes difficult to maintain the crusher. On the other hand, also in the above-described conventional self-propelled soil improvement machine, the engine is located at a high position behind the machine body. As a result, the position of the center of gravity of the engine becomes high and stability is lost.
[0005]
As a technique for solving such a problem, in Japanese Patent Application No. 2001-379162, the applicant inputs a crushing device, a power source that drives the crushing device, and an object to be crushed by the crushing device. A hopper, a feeder that conveys the material to be crushed to the hopper, and a self-propelled carriage on which these are mounted, and a power source is provided on either side of the self-propelled carriage. Proposed a self-propelled crusher in which a hopper and a hopper are arranged side by side and a crushing device 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 apparatus having the largest weight, the compactness and the stabilization of the weight balance can be achieved. Then, from the viewpoint of installation space and maintenance, the engine fuel tank, which is a power source, is disposed below the hopper sliding plate on the counter-power source side with the hopper interposed therebetween.
[0007]
However, when this arrangement is adopted, the fuel tank has a substantially rectangular parallelepiped shape, and the upper surface is flat, and the fuel supply port is also provided. They collide with the base of the fuel supply port and damage them. In addition, extra work to remove the crushed material that accumulates on the upper surface of the tank and removes the accumulated crushed material every time the fuel is supplied, and the accumulated dust etc. are mixed during the fuel supply, thus extending the life of the fuel filter. There was a problem that it would be extremely short.
[0008]
Such a problem also occurs in the self-propelled soil improvement machine as long as the hopper and the power source are arranged side by side.
