Description

DETAILED DESCRIPTION OF THE INVENTION The invention of this application relates to a bucket device for scooping up dirt and a long object gripping device.

Conventionally, bucket equipment for scooping soil has been adopted as a method of scooping soil using a power shovel bucket or a clamshell bucket type soil scooping method, each suitable for each purpose. . However, in the case of civil engineering construction, there is no work with the same conditions throughout the year, but when the work is completed for a relatively short period of time,
There is a drawback that the bucket apparatus must be carried to another place where the work is to be done, or left at that place until the next work is to be done.

In addition, the conventionally known Japanese Patent Publication No. 54-37403 discloses a first bucket part having a bottom plate and two side walls; a second bucket part mounted thereon; a hydraulic actuator mounted on both of the bucket parts and operable to mutually pivot the bucket parts between a closed position and an open position; When the part is in the closed position, the bottom plate of the bucket part consists of an overlapping excavation bucket part and a material handling part and a mounting part rigidly connected thereto, the mounting part being connected to the whole of the first set and the second set. each of the engagement surfaces being associated with a respective surface defined by the bucket portion, the first set of engagement surfaces engaging the second set of engagement surfaces. A bucket is described that has a material handling attachment that is removably connected to the bucket at a location that is approximately perpendicular to the engagement surface of the bucket. An excavation bucket is described in which an auxiliary peripheral wall for increasing volume is removably attached to the peripheral edge of the opening. However, the devices described in those two publications cannot reliably scoop up dirt and grip long objects.

The invention of this application aims to eliminate the above-mentioned drawbacks.

Next, the specific configuration for achieving the above purpose will be explained according to the drawings.
1' and an opening/closing bucket 2' are arranged facing each other, and both buckets 2, 2'
is pivotally supported by a pivot pin 3, and the upper shoulders of both the buckets 2 and 2' are connected by a hydraulic cylinder 4, and the position of the cylinder stop pin 4' of the hydraulic cylinder 4 and the hydraulic cylinder The position of the line connecting the position of the cylinder stop pin 4' at the end of the piston rod 4 is always located above the position of the pivot pin 3, and a pin hole 9 is formed in the piston rod portion of the hydraulic cylinder 4. A spring 12 is interposed between the spring bush stopper plate 10 on the side and the stopper plate 10 opposite thereto, and the center part of the pin hole 9 attached to the piston rod part by the spring 12 is used to prevent the piston rod from expanding. The eye of the piston hole 9 is prevented from coming out of the piston rod by the nut 13 and the lock nut 14,
On the side wall surface of the opening/closing bucket 2', there is provided a blind plate 5 made of iron plate which can be attached and detached with bolts 7, 7'. Place the cushion rubber 6, 6' at the position,
This is a bucket cart device for scooping up sand and a long object grasping device which can be made into a closed structure so that sand and sand do not flow out from anywhere when both opposing bucket carts 2 and 2' are closed.

Next, we will describe the functions and effects resulting from the above configuration. In order to scoop up dirt with the bucket device for scooping dirt of the present invention, the scooping bowl-shaped structures of the two opposing buckets are wide open, and the scooping bowl-like structures of the two buckets facing each other are By bringing the claws at the lower ends of the two buckets closer to each other, it is possible to reliably trap a large amount of earth and sand in the bucket. By arranging shock absorbers made of rubber or the like at the base of the peripheral edges of the side walls of the two facing buckets, it is ensured that dirt, etc. will not get caught between the peripheral edges of the side walls of the buckets that are close to each other. This has the effect that the peripheral edge portions of the side wall surfaces of the facing buckets can be brought into contact with each other, thereby ensuring that the earth and sand in the bucket can be caught.

Next, in order to use the bucket device for scooping earth and sand of the present invention as a long object grasping device, it is attached to the bucket main body in a substantially semicircular or elliptical shape including the peripheral edge of the side wall surface of the bucket.
And a removable steel blind board is installed,
By removing the eyelet on the side wall of the semicircular or elliptical bucket, a space is formed in the center of the opposing bucket to hold a long object, such as a concrete pile, a wooden column, or other objects. By gripping a long object from both sides with the gripping claws made of the bucket main body, there is an effect that the long object can be reliably gripped. In particular, the bucket part can support a long object at an appropriate distance in the width direction, which has the effect of preventing it from swinging in the left-right direction.

In addition, since the eye of the pin hole 9 attached to the piston rod is constantly biased by the spring 12 in the direction in which the piston rod extends, pressure oil flows into the piston rod extrusion side of the hydraulic cylinder 4 and the hydraulic pressure increases. When applied, the piston rod extends, and the force of the spring 12 supports the eye of the pin hole 9, causing the main body bucket 2 and the opening/closing bucket 2' to rotate in the direction of closing, and ultimately maintain the closed state. effective. Furthermore, if a problem occurs in the hydraulic cylinder 4, the nut can be removed and the hydraulic cylinder 4 can be easily replaced or repaired. In addition, since the hydraulic cylinder 4 is located above the pivot pin 3, the space inside the bucket can be made extremely wide, and there is no risk that the earth and sand in the bucket will come into direct contact with the hydraulic cylinder 4 and damage the hydraulic cylinder 4. There is no effect. In addition, when both buckets 2 and 2' facing each other are closed, it can be used as a closed structure to prevent earth and sand from flowing out anywhere, so even the slightest amount of pollutants or strange odors that are prohibited to flow out can be emitted. Even if the transfer process is carried out reliably, it is effective.

In the case of gripping a long object, it is necessary to perform rotational movement when moving the gripped long object, but in order to perform such work, the long object gripping device of the invention of this application is required By incorporating a mechanism for rotating the support shaft, such as a gear-type rotational force transmission mechanism, even a long object can be rotated very reliably and moved to a desired position.
