Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tip handling apparatus.

[0002]

2. Description of the Related Art As shown in FIG. 6, the conventional tip loading and unloading work of a tipping vessel is performed by putting a working machine 8 such as a power shovel or a bulldozer into a hold 7 (holding) of the tipping ship 1 and using the working machine 8. The chip 4 is scraped near the center of the hold 7, and the scraped chip 4 is gripped by a land clamshell bucket 3 or the like and moved to a conveyor device 6 or the like having a hopper 5 on the land side. The chip 4 attached to the wall surface was scraped off manually.

Generally, the inside surface (wall surface) of the hold 7 is uneven, and the corners and the like have a narrow structure. Since the chips are housed therein, there is also added freedom of consolidation, so that the chips are considerably wall surfaces. It seems to be firmly attached (fixed).

[0004]

However, the conventional system has the following problems. (1) Labor In a bad environment, it is hard work to manually scrape the chips attached to the wall of the hold. (2) A work machine for scraping chips and a scraping staff are mixed in a narrow hold, which poses a safety problem. (3) Human efficiency is low. (4) Dangerous when working in high places.

The present invention was developed to address such problems, and it is an object of the present invention to enable scraping and scraping of chips with a single working machine.

[0006]

In order to achieve the above object, the present invention provides a scraping claw 11 which is attached to a tip end of a swing arm 22 of a working machine 17 such as a power shovel through a connecting metal fitting 12, and the scraping claw 11. In a chip handling device comprising a scraping claw 11 and a scraping bucket 10 that is detached and attached via a lock device 16 built in the scraping claw 11, a nozzle diameter 2 for ejecting high-speed air at the tip of the scraping claw 11
It is characterized by being equipped with an air jet nozzle 26 of 0 mmφ or more.

[0007]

According to the above-mentioned means of the present invention, the chip is scraped off mechanically by a scraping claw, and by a method in which the chip is fluidly scraped by an air nozzle jet equipped on the claw, both are simultaneously used. Scraping off the tip (mechanically scraping off with a nail while ejecting air) is used depending on the nature of the tip and other factors. After scraping the chips all the way from the wall surface, the scraping claws are combined with the bucket and the locking device built into the claws integrates the bucket and the claws, and the bucket scrapes the chips toward the center of the hold. The scraping claws are "spatular" shaped and can be easily inserted into the mounting space on the back of the bucket for integration or vice versa.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, a power shovel is used as a working machine 17, and a blower 18 is mounted on the rear part. The boom 21, which is a link mechanism, and the arm 22 are equipped with scraping claws 11 and a (wide) bucket 10 at the tips thereof.

2 and 3 show detailed views of the tip portion thereof.
The scraping claw 11 has a shape like a “spa” and is used for scraping off a chip fixed on the wall surface of the hold. The scraping claws 11 are inserted into the recesses on the back surface of the bucket 10 and appropriately connected integrally by the lock device 16. Scraping claw 11
Is connected to an arm 22 via a connecting fitting 12, and a swinging jack 14 is attached between the two. Scraped nail 1
A lock device 16 is built in the inside of the device 1. A wedge 24 is attached to the tip of the lock jack 23, and two sets of front and rear lock devices 16 are attached to the slope. A spring 25 is provided so that the locking device 16 contracts when the wedge 24 is pulled. Reference numeral 26 is an air jet nozzle, which is supplied with air from the blower 18 through an air pipe 20 and has a nozzle diameter of 20 mmφ or more for blowing off chips.

Thus, when the bucket 10 is installed, it has the same function as a normal power shovel, and the boom 21,
The arm 22 and the bucket 10 are operated to scrape the tip to the central position. It is also possible to appropriately swing the bucket 10 left and right by the function of the swing jack 14. Next, when scraping off the chips attached to the wall surface of the hold, the bucket 10 is once removed. The point is that the bucket 10 and the scraping claw 11 are unlocked by contracting the fully extended lock jack 14 (direction (D) in FIG. 2).
1 is pulled out in the direction of (a) in FIG. 2 and the bucket 10 is removed. After that, the scraping claws 11 are scraped off by mechanically pushing the scraping claws 11 against the chip on the wall surface or by jetting an air jet. The swinging jack 14 is effectively used to approach the narrow portion so that it is closer to the wall surface.

FIG. 5 is a measurement diagram showing the experimental results of the degree of chip scattering depending on the nozzle diameter and the flow velocity. Nozzle diameter is 20m
When mφ, the wind speed is 250 m / s or more and the nozzle diameter is 25
When mmφ, the wind speed is 230 m / s or more, and the nozzle diameter is 2
At 7 mmφ, the wind speed was 210 m / s or more, and the chip scattering condition was good.

[0012]

As described above, according to the present invention, the scraping claw attached to the tip end of the swing arm of the working machine through the connecting fitting and the scraping claw via the locking device incorporated therein. Since it is composed of a scraping bucket that is detached and attached, the scraping work of the chip by the scraping claw and the scraping work by the scraping bucket mounted on the scraping claw are performed by one working machine. Safety is improved without requiring human power for cargo handling work, and even in a narrow space, the operation of the boom, arm, and swing can be combined to approach the wall surface (scraping) to the last minute, and be equipped with an air jet. This has the effect that chips can be safely removed without damaging the wall surface.
