Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ground excavator for a bucket for use in a civil engineering machine such as a shovel loader or a power shovel.

[0002]

2. Description of the Related Art The present inventor has filed a utility model registration No. 200678.
In No. 5 (Japanese Utility Model Publication No. 5-12366), "The ground plate for mounting the claw of the scooping member in the bucket body is divided into a plurality, and a joint is provided on one side of each divided piece of the ground plate. Provided on each of the divided pieces, each divided piece detachably attached to the hoe claw mounting portion via a lock pin with a ground level plate mounting tool using a hoe claw of a scooping member in the bucket body by a joint. And a bucket for civil engineering shovels, characterized by being connected. As a result, the ground leveling work after excavation can be performed manually and with high accuracy in a short time with a shovel machine, and its effectiveness has been firmly used by large and small companies in the industry.

[0003]

However, in the above registered utility model of the present applicant, when shifting from excavation to leveling work, each divided ground level piece constituting the leveling board is removed from the tooth member of the bucket. There is a need. And, because the ground level is made of steel and thick to withstand high loads, it is heavy and heavy. It takes the power of. Also, the work of attaching and detaching the divided pieces to and from the tooth members of the bucket requires considerable labor and involves danger.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, once mounted on a tooth member of a bucket, excavation and leveling can be performed alternately without detaching and attaching the rest.

[0005]

Means for Solving the Problems To achieve the above object, a first aspect of the present invention is a leveling method for both digging and excavation, in a bucket of a shovel machine for forming a leveling ground body by a plurality of divided leveling pieces. The excavation claw provided along one side of each leveling piece to be attached to the tooth member of the bucket body slides downward during excavation and projects downward from the lower edge of the leveling ground body, and retracts to the lower edge during leveling. Is to make it

A second aspect of the present invention is a digging and grounding machine, in which a shovel machine bucket for forming a terrain body with a plurality of terrain pieces is used for mounting to a tooth member fixed to a bucket body. A groove-shaped guide is provided on one side of the grading piece, and the excavation claw is arranged so that it can slide up and down along the guide. When the excavation claw is retracted to the lower end side for leveling, the excavation claw is hooked to the groove-shaped guide with a stopper.

[0007]

According to the present invention, in the above structure, a plurality of ground shaping pieces are combined to form a ground shaping body, and excavation claws are formed along a groove-shaped guide integrally formed on one surface of the shaping ground body. Be able to move while sliding. When excavating, the tip of the excavation claw is projected downward from the lower end side of the ground preparation body, and then the excavation claw is connected to the groove-shaped guide with a lock pin and latched on the ground preparation body side. Further, when leveling the ground, the excavation claw is retracted until the excavation claw is slightly retracted from the surface of the ground preparation body or the surface position, and then the excavation claw is connected to the groove-shaped guide with a lock pin and latched on the side of the ground preparation body.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a horizontally long ground grading body, which is divided into a plurality of ground grading pieces.
It is formed by combining 1a to 1n. 2
Is an excavating claw slidably mounted on each of the terrain pieces, and sliding wing pieces 21 are formed on both right and left sides thereof so as to protrude. In the case of FIGS. 4 and 5, the tip portion of the sliding wing piece is tapered by being cut obliquely. It can also be left as. Reference numeral 3 denotes a lock pin hole for connecting each of the terrain pieces to the tooth member of the bucket body. Reference numeral 4 denotes a groove-shaped guide for sliding the excavating claw 2, which is integrally formed on one surface of the grading pieces 1a to 1n. In addition, a part of the bottom of the groove-shaped guide forms a gap G by the thickness of the sliding wing piece of the excavating claw. Reference numeral 5 denotes a hole formed in the side surface of the excavation claw 2, and reference numerals 5 'and 5 "denote holes formed in the side surface of the grooved guide 4. Reference numeral 6 denotes a stopper inserted through the hole of the excavation claw and the grooved guide. In the illustrated example, the cross section is key-shaped.
7 is a bucket main body, 8 is a tooth member provided on the lower end side 7 'of the bucket main body, 9 is a lock pin for connecting each of the leveling pieces 1a to 1n to the tooth member 8, and 10 is provided on the leveling piece. It is a socket portion into which the tooth member 8 is fitted.
Numerals 11 and 11 'denote joining wings that protrude to the left and right sides of each grading piece. One of the wing pieces 11 is formed with a step to join with the wing piece of an adjacent grading piece. Numerals 12 denote holding blades provided on the left and right sides of the groove-shaped guide, and have a gap G corresponding to the plate thickness of the sliding blades 21 of the excavating claws. In FIG. 1, reference numeral 13 denotes a shovel machine, 14 denotes a cab, 15 denotes a swiveling boom, 16 denotes an arm, and 17 denotes a connecting shaft.

[0009]

[Application example] An application example based on the above configuration is as follows. "Attachment of the ground preparation body to the bucket" The excavation claw 2 is fitted into the tooth member 8 from the upper end side of the ground preparation pieces 1a to 1n that have been divided in advance, and the lock pin 9 is inserted and connected.

[Excavation Claw During Excavation Work] The excavation claw 2 for excavation slides the excavation claw 2 downward along the groove-shaped guide 4 on one side of the ground preparation body 1. Then, in the excavation work, after the tip of the excavation claw is projected downward from the lower end side 1 ′ of the ground preparation body 1, the stopper 6 is attached to the excavation claw 5.
Then, the excavation claw 2 is inserted into the hole 5 "of the groove-shaped guide and the excavation claw 2 is mounted on the ground body side.

[Excavation Claws for Leveling Work] The excavation claws 2 for leveling slide the excavation claws 2 upward along the groove-shaped guides 4 on one side of the ground preparation ground body 1. Then, in the excavation work, after the tip of the excavation claw is retracted from the lower end side 1 ′ of the ground preparation body 1 and the surface position or the surface position, the stopper 6
Into the hole 5 of the excavation claw and the hole 5 'of the grooved guide, and attach the excavation claw 2 to the side of the ground preparation body.

[0012]

According to the present invention having the above-described structure, the following effects can be obtained. First, once the ground preparation body is once mounted on the tooth member of the bucket body, excavation and ground preparation can be performed easily and reliably without detachment. That is, when the excavation claw is slid downward along the concave groove-shaped guide of the plurality of divided leveling pieces constituting the leveling ground body, the tip of the excavation claw protrudes downward from the lower end side of the ground preparation ground body to perform excavation work. . Then, when the excavation claw is slid upward along the concave groove guide, the excavation claw tip is retracted from the lower side and the surface position or the surface position of the ground preparation body, and the leveling operation can be performed. And it is new useful as a ground for excavation.
