Description

The present invention relates to a self-propelled crusher, and more particularly to a self-propelled crusher provided with a canopy.

The self-propelled crusher includes a machine body having a crushing device input port opened upward on the traveling body into which the material to be crushed is thrown, and the generated crushed material is carried out of the machine body by a discharge conveyor. (For example, see Patent Document 1).

Self-propelled crushers are transported between work sites on trucks, trailers, etc., and perform crushing work at outdoor work sites. The self-propelled crusher can be self-propelled in a work site and moved to an arbitrary place. There are various types of materials to be crushed, such as raw stones in quarries, concrete lumps generated during building demolition, and asphalt lumps generated during road construction.

The crushing device and the input port for the object to be crushed are installed at the approximate center of the machine body, and work decks are formed on both the left and right sides of the machine body in the vicinity so that workers can get on and off. Workers ride on this work deck to operate, check and maintain the self-propelled crusher.

The canopy 24 will be described with reference to FIG. 4 which is an enlarged side view of a portion of the canopy 24 and FIG. 5 which is a partial front view, together with FIGS.

The roof 26 is formed in a rectangular substantially flat plate shape, and the size of the rectangle is such that the left and right side decks 18a and 18b of the airframe 8 are positioned when the roof 26 is "up position" (indicated by a two-dot chain line in FIG. 4). It is formed in a size that substantially covers the entire work deck 18 (FIG. 3). The roof 26 is formed by a material known as a canopy roof, for example, a canvas or plastic stretched on a steel frame, or integrally formed of reinforced plastic. The roof 26 is connected to a pair of left and right quadrilateral link members 30 and 31 of a support means 28, which will be described in detail later, on both sides in the left and right width direction, and a pin connecting portion P1 having pins extending in the left and right width direction. , P2 is provided.

The support means 28 includes a pair of stands 32 and 33 attached to the side decks 18 a and 18 b, and quadrilateral link members 30 and 31 attached between the stands 32 and 33 and the roof 26. . The stands 32 and 33 and the quadrilateral link members 30 and 31 are formed symmetrically in the left-right width direction of the machine body 8 (perpendicular to the paper surface of FIG. 4 and left-right direction of FIG. 5). Therefore, the details will be described using one stand 32 and the quadrilateral link member 30.

The stand 32 is formed of a steel member, mainly a steel plate, in a Y shape when viewed from the side (FIG. 4) and an L shape when viewed from the front (FIG. 5), and a base 32a that is the bottom of the L shape is a work deck. 18 (18a) is fixed by bolts, and a vertical portion 32b which is a vertical side extends along the handrail 22 to the upper side thereof. The Y-shaped bifurcated portion includes pin connecting portions P3 and P4 each having a pin extending in the left-right width direction of the airframe 8 to which the quadrilateral link member 30 is connected. An upright portion 32 b of the stand 32 is fixed to the handrail 22.

The quadrilateral link member 30 is a pair of links, as viewed from the side (FIG. 4), one link 30a connected to the pin connecting portions P1 and P3 and the other link 30b connected to the pin connecting portions P2 and P4. Are substantially parallel, that is, substantially parallelograms are formed by P1, P2, P4, and P3. A reinforcing link 30c is inserted between the links 30a and 30b in the longitudinal direction and is connected to each other by pins so as to be rotatable. These links 30a, 30b, and 30c are formed by cutting a strip-shaped steel plate into a predetermined length and providing a pin hole at a predetermined position.

The roof 26 is moved by the quadrilateral link member 30 (31) from the “lower position” (shown by a solid line in FIG. 4) toward the “upper position” (shown by a two-dot chain line in FIG. 4). It is installed so as to “hang out” horizontally from the “position” and to cover the inlet 6 (FIG. 3) of the crushing apparatus in the “lower position”. The roof 26 is also disposed by the quadrilateral link member 30 (31) as viewed from the side (FIG. 4), substantially horizontally at the “up position” and slightly at the end in the overhang direction at the “down position”. ing.

By arranging the roof 26 by the quadrilateral link member 30 (31) as described above, the projecting end of the roof 26 that moves between the “lower position” and the “upper position” is an arc-shaped locus indicated by a two-dot chain line. 34 is moved to provide a space for the worker standing on the work deck 18. Therefore, the operator can move the roof 26 between the “upper position” and the “lower position” without getting off the deck 18.

Between the link 30 b in the longitudinal direction and the stand 32, a hydraulic cylinder 36 is provided as a roof moving means for driving the movement of the quadrilateral link member 30 relative to the stand 32, that is, the movement of the roof 26. The hydraulic cylinder 36 is expanded and contracted by supplying and discharging pressure oil from the hydraulic source of the power unit 16 by an operation of an operation switch (not shown) by an operator on the work deck 18. Instead of the hydraulic cylinder 36, auxiliary means such as a gas cylinder using a compressed fluid that assists the manual movement of the roof 26 or a spring cylinder using a spring may be employed.

When the roof 26 is in the “down position” of the stand 32, the pin hole F <b> 2 provided in the roof 26 is aligned with the pin hole F <b> 1 provided in the vicinity of the pin connecting portion P <b> 2 of the stand 32, thereby inserting the pins into each other. The position can be fixed at the “lower position” so as not to move. That is, when the self-propelled crusher 2 is transported on a truck, trailer or the like, the roof 26 can be reliably held and fixed at the “lower position”.

The operation of the self-propelled crusher 2 as described above will be described mainly with reference to FIGS.

According to the self-propelled crusher 2, the body 8 is provided with the canopy 24, and the roof 26 of the canopy 24 is positioned above the work deck 18 near the inlet 6 of the crushing apparatus and the body 8. It is movably attached between the “lower positions” that descend to the side. Therefore, the size of the roof 26 according to the work deck 18, that is, the size shown in FIG. 3 that substantially covers the entire work deck including the left and right side decks shown in FIG. For example, it is possible to significantly improve the working environment of the worker under hot weather.

When transporting the self-propelled crusher 2 on a truck, trailer, etc., the overall height of the self-propelled crusher 2 is shown in FIG. 1 by moving the roof 26 of the canopy 24 to the “down position”. It can be significantly lowered from H1 to H2 shown, and public roads with height restrictions can be easily transported.

At the time of transportation, the roof 26 can be securely held and fixed at the “lower position” by inserting the pin with the pin hole F2 of the roof 26 aligned with the pin hole F1 of the stand 32. Further, since the projecting end side of the roof 26 at this “lower position” is arranged slightly downward, the air resistance during transportation in which the discharge conveyor 10 side is in the vehicle traveling direction is minimized, and no pins are inserted by any chance. However, the roof 26 of the canopy 24 can be prevented from opening during transportation.

At the roof 26 "down position" of the canopy 24, the roof 26 covers the inlet 6 (FIG. 3) of the crushing device so as to cover it, so that tools, foreign objects, etc. can be prevented from inadvertently dropping into the inlet 6. .
