Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a self-propelled stone picking and transporting machine suitable for use in picking up stones at construction sites.

[Conventional technology]

Conventionally, at dam construction sites, workers dig up stones in the core zone using shovels, and then manually carry the stones and dump them into lock zones on both sides.

[Problem that the invention attempts to solve]

However, since large construction machines run crisscrossing the core zone, manually carrying out the stone extraction work is not only dangerous but also inefficient.

In view of the above points, the present invention aims to provide a self-propelled rock picking and transporting machine that can ensure the safety of workers and has a light load.

[Means for solving problems]

The rock picking and transporting machine of the present invention has a base end of a Betsusel support frame pivotally attached to the front of a self-propelled work vehicle equipped with a rock picking claw that expands and contracts at the tip of a movable arm, and this support frame A tilt cylinder is provided between the support frame and the vehicle body, and the tip of a vessel is pivotally connected to the swinging end of the support frame, and the vessel is mounted between the vessel and the support frame. It is equipped with a dump cylinder that can be tilted.

[Effect]

According to the present invention, digging work is carried out using stone picking claws attached to a self-propelled work vehicle, and the dug stones are picked up by the claws into a vessel equipped in front of the worker and transported to the rock zone. However, this can be easily disposed of by the dumping operation of the vessel.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a side view showing the overall configuration of the stone picking and transporting machine according to this embodiment, and FIG. 2 is a front view thereof.
In the figure, reference numeral 1 denotes a well-known self-propelled work vehicle equipped with a rock picking claw 3 by an attachment at the tip of a movable arm 2, and a betsu cell support frame is attached to the front of the vehicle body 4 as shown in detail in FIGS. 3 to 5. The proximal end of the body 5 is pivotally connected via brackets 6, 6 on both sides integral therewith.

These brackets 6, 6 have an arm 6 extending upward perpendicularly to a line connecting the pivot portion and the support frame 5.
a, 6a, and a pair of tilting cylinder devices 7, 7 for lifting the support frame 5 are arranged between the ends of these arms 6a, 6a and the vehicle body 4,
Both ends thereof are pivotally connected to the arm 6a and the vehicle body 4, respectively.

The tip of the vessel 8 is pivotally attached to the swinging end of the support frame 5, and the bottom 8 of the vessel 8 is pivotally attached to the support frame 5.
a is formed so as to be housed within the support frame 5. Further, a pair of dump cylinders 9, 9 for tilting the vessel are arranged on both sides of the vessel 8, and both ends of the cylinders 9 and 9 are located at a position above the pivot point of the base end of the vessel and the support frame 5. They are each pivoted to the

Because it has the above configuration, the rock picking and transporting machine according to the present embodiment performs stone digging work by operating the movable arm driving cylinder device 2a and the rock picking claw driving cylinder device 3a of the self-propelled working vehicle 1 in the core zone. Then, the excavated stones are collected into Bethusel 8. When the collected stones reach a predetermined amount, they are transported to the lock zone, but in order to prevent the vessel 8 from coming into contact with obstacles while traveling and to prevent spillage, the tilting cylinder device 7 is installed in advance. 7 lifts up the Bethel 8 and transports it in this state. In the lock zone, the vessel 8 is tilted by operating the dump cylinder devices 9, 9, and stones inside the vessel 8 are removed. All of the above operations are performed by operating a lever in the driver's seat (not shown).

The hydraulic circuit shown in FIG. 6 shows that the hydraulic pumps for the tilt cylinder devices 7, 7 and the dump cylinder devices 9, 9 are common, and are operated by switching the respective valves.

[Effect of idea]

As described above, according to the present invention, digging work is carried out using a stone pick-up claw attached to a self-propelled work vehicle, and the dug stones are transferred to the vessel installed in front of the worker. It is possible to pick up waste with its claws, transport it to the lock zone, and easily dispose of it by the dumping operation of the vessel.
It is easy to ensure safety and has the effect of significantly improving work efficiency.
