Description

[Detailed description of the invention] [Industrial application field] The present invention is designed to use the front end of the traveling vehicle of road finishing machines such as asphalt finishers, repavers, and remixers in order to push dump trucks loaded with asphalt mixture, etc. The push roller provided in the section,
This invention relates to a storage device for storing the product out of the way when work is completed.

[Conventional technology]

In road finishing machines, in order to receive asphalt mixture from a dump truck into a hopper while continuing work, a push roller installed at the front end of a traveling vehicle, which is a road finishing machine, pushes the rear wheels of the dump truck to move the dump truck. Asphalt mixture is being supplied while the plant is in operation.

By the way, in relatively small road finishing machines, the width of the running vehicle is restricted due to transportation issues or the width of the construction site, so it is difficult to make the width narrower than the installed width of the left and right rear wheels of a dump truck. There is.

Conventionally, a push roller is attached to such a road finishing machine using several bolts so that it can freely retract and protrude in the width direction of the road finishing machine. After the work is completed, the push roller is retracted so that transportation of the road finishing machine is not hindered.

[Problem that the invention attempts to solve]

However, with the above structure, it is necessary to loosen and tighten several bolts one by one each time the push roller is moved in and out, which makes the operation complicated and time-consuming, resulting in poor workability.

[Means for solving problems]

In the present invention, the inner edge of the hopper wing is attached to the front part of the vehicle by a hinge shaft so that it can freely rotate up and down in a plane substantially perpendicular to the width direction of the vehicle.
A tilting arm is provided at the front end of the vehicle, the inner end of which is pivotally connected to the vehicle by a pivot so that the arm can be raised and lowered up and down in a plane substantially perpendicular to the width direction of the vehicle;
A push roller is attached to the tilting arm so that the axial direction of the push roller is aligned almost parallel to the length direction of the tilting arm, and is rotatable in the circumferential direction. The above-mentioned conventional problems are solved by providing an interlocking member such as a wire that raises and lowers the push roller in conjunction with the push roller.

[Effect]

During work, the hopper wing is rotated downward by a hydraulic cylinder or the like and opened to the left and right so that it can receive a large amount of asphalt mixture. At this time, the interlocking member pulls the tilting arm that had been standing upward until then, and lowers the tilting arm in conjunction with the downward rotation of the hopper wing. The push roller is folded down together with the tilting arm, protrudes horizontally to the side of the vehicle, and is placed in a position to press the rear wheels of the dump truck.

Further, when the road finishing machine is to be transported on a truck after the work is completed, the hopper wing is rotated upward by a hydraulic cylinder or the like. At this time as well, the interlocking member pulls the raising/lowering arm, raises it upward together with the push roller, and stores it above the vehicle.

〔Example〕

Figures 1 to 3 show an embodiment of the present invention, and 1 is a crawler-type traveling vehicle. As is well known, at the front of the vehicle 1, a hopper wing 2 is pivotally connected at its inner edge by a hinge shaft 3, so that it can freely rotate up and down in a plane substantially perpendicular to the width direction of the vehicle 1. It is provided. Further, at the front end of the vehicle 1, a tilting arm 4 has its inner end (the left end in FIG. 2) pivotally connected to the vehicle 1 by a pivot 5. It is provided so that it can be raised and lowered freely in a plane that is substantially perpendicular to the width direction. A push roller 6 is attached to the tilting arm 4 with its axial direction substantially parallel to the length direction of the tilting arm 4, and is rotatable in the circumferential direction by a mounting shaft 7 provided with a grease nipple. There is.

Reference numeral 8 denotes an interlocking member, one end of which is fixed to the free end of the lifting arm 4, and the other end fixed to the hopper wing 2.
It is provided so as to be removably hooked onto a hook metal fitting 9 provided in the. This interlocking member 8 links the vertical movement of the hopper wing 2 with the hinge shaft 3 as the fulcrum, and the raising and lowering of the tilting arm 4, that is, the push roller 6, with the pivot shaft 5 as the fulcrum. Wires, links, etc. are usually used. As is well known, the hopper wing 2 can be rotated up and down about a pivot 5 using a hydraulic cylinder or the like (not shown).
Further, the hopper wing 2, the raising/lowering arm 4, etc. are provided symmetrically on the left and right sides of the traveling vehicle 1.

Reference numeral 10 denotes a stopper for stopping the tilting arm 4 and maintaining the push roller 6 in a horizontal state, and is fixed to the traveling vehicle 1 by a fixing means such as welding.

Next, the operation of the push roller storage device in an asphalt finish or the like according to the present invention will be explained.

The solid lines in FIGS. 1, 3, and 2 indicate the working state in which the hopper wing 2, the tilting arm 4, etc. are rotating downwards, and in this state, the traveling vehicle 1 is in the position of the dump truck. Asphalt mixture is supplied from the dump truck to the hopper while touching the push roller 6 to the rear wheel 11 (Fig. 1) and pushing it to the left in Fig. 1. When the asphalt finish or the like is to be transported by truck or the like after the work is completed, the hopper wing 2 is rotated upward about the hinge shaft 3 by a hydraulic cylinder or the like. At this time, the interlocking member 8 hooked to the hook fitting 9 of the hopper wing 2 pulls the free end of the tilting arm 4 upward, and raises the tilting arm 4 upward together with the push roller 6 using the pivot 5 as a fulcrum. let By this operation, the hopper wing 2, the raising/lowering arm 4, and the push roller 6, which had been protruding from the side of the vehicle 1, are retracted from the side of the vehicle 1 directly above the vehicle 1.

When the asphalt mixture placed in the hopper is running low, the hopper wing 2 is rotated upward as in the conventional method to collect the asphalt mixture in the center of the hopper. At this time as well, the raising/lowering arm 4 and the push roller 6 stand upward, but if the raising/lowering arm 4 and the push roller 6 are in a condition where it would be difficult for them to stand upward, the interlocking member 8 may be removed from the hook fitting 9. Remove it and rotate only Hoppa Wing 2 upwards.

[Effect of idea]

As explained above, in the push roller storage device for an asphalt finisher, etc. of the present invention, a tilting arm equipped with a push roller is provided on a traveling vehicle so as to be freely tiltable, and the tilting arm is connected to a hopper wing by an interlocking member. The lift arm and push roller are connected to each other and are configured to move up and down in conjunction with the up and down movement of the hopper wing, so each time the push roller is protruded from the side of the vehicle or retracted, it does not need to be moved like a conventional There is no need to loosen or tighten bolts one by one, and the push roller can be quickly and precisely retracted and fixed to the side of the vehicle.

In addition, ruts, etc. have occurred on the unrenovated road in front of the road finishing machine, and the relationship between the dump truck and the road finishing machine does not match due to the difference between wheels and crawlers, and the push roller is the rear wheel of the dump truck. Even if a situation occurs in which the push roller does not make proper contact with the rear wheel of the dump truck, the push roller can be brought into proper contact with the rear wheel of the dump truck by changing the length of the interlocking member and adjusting the condition of the push roller.
