In place of the above, the excavation bucket device for rotary long object grasping is configured to be replaced with a direct excavation bucket or other swivel-type work tool so that various operations can be performed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotary excavation bucket device for gripping a long object.

[0002]

[Prior art]

 Conventionally, a bucket attached to the tip of an arm of a power shovel or the like was a single bucket, and the shape of the bucket was bowl-shaped, and it had only the function of scooping from one direction. Therefore, there was no function to grab or rotate.

[0003]

[Problems to be solved by the device]

 According to the present invention, various work can be performed by attaching a bucket having a function of gripping with two buckets and a function of rotating in place of one bucket attached to the tip of the arm of the conventional power shovel, etc. The first object is to provide a rotary type long object holding excavation bucket device capable of performing the above-mentioned operation. Further, by exchanging the bucket with a cylindrical bucket piece, direct excavation is performed. The second purpose is to do so.

[0004]

[Means for Solving Problems]

 Next, the technical means for achieving the above-mentioned object will be described. The specific configuration of the present invention is that a rotary shaft is fitted and hung down in an opening provided in a fixed portion, and the rotary shaft is opposed to an appropriate position at the lower end of the rotary shaft. To provide a pivotal support for a gripping member with a bucket piece that is long in the lateral width direction, and to grip a long object to be gripped by these opposing gripping members that are long in the lateral width direction, and adjust its direction for movement. At the center of the lower end of the fixed part, mounting openings for the bases 6 of the semicircular claw-shaped bucket pieces 5, 5'opposite each other are provided, and at the openings, the bases 6 of the bucket pieces 5, 5'are provided. Is rotatably loaded so that the bucket pieces 5 and 5'can be rotatably operated, and the rotary bucket device is replaced with a direct excavation bucket or other swivel type work implement to directly excavate. Excavation or other work A rotary elongated object gripping bucket equipment made as capable of carrying out.

【Example】

 Next, an explanation will be given of a rest structure of an embodiment of the present invention for achieving the above object by referring to the drawings, in which the fixing portion 1 is located at the tip of an arm of a power shovel or the like, and the pin hole of the fixing portion 1 is arranged. The fixing portions 1 and 2 are fixed by fixing pins at the central portion of the lower end of the fixing portion 1 and are provided with opening portions for attaching the base portions 6 of the semicircular claw-shaped bucket pieces 5 and 5'that face each other. The base 6 of the bucket pieces 5 and 5'is rotatably inserted into the opening, and the upper end flange portion 7 of the base 6 and the base 6 of the bucket pieces 5 and 5'at the center of the lower end of the fixed portion 1 are inserted. By interposing bearings 8 and 15 between the mounting opening and the peripheral portion thereof, the bucket pieces 5 and 5 ′ are easily rotated, and the hydraulic motor 9 is disposed at an appropriate position of the fixed portion 1. External gear 10 is directly connected to hydraulic motor 9, and internal gear meshes with external gear 10. 1 is provided, and the shape of the central through hole of the rotary plate 12 integrated with the internal gear 11 thereof is made to match the shape of the outer periphery of the base portion 6 of the bucket pieces 5 and 5 ′ so that they can integrally move together. The bucket pieces 5 and 5'are sandwiched with each other so that a grasped object such as a long object can be grasped, and one bucket piece is centered on the pivotal support portion 14 of the bucket piece and the other bucket piece. A hydraulic cylinder 13 is provided between the two bucket pieces so that the bucket pieces can be separated from each other. Is a rotary type long object gripping excavating bucket device configured to feed oil and to cause the hydraulic cylinder 13 to act.

[0006]

[Operation effect]

 Next, the operation and effect of the above structure will be described. A long object such as a concrete pile or a wooden pillar is securely gripped and rotated by semi-circular claw-shaped or other appropriately shaped bucket pieces opposed to each other. There is an effect that can be. Further, since the bucket portion is relatively long in the lateral width direction, there is an effect that a long object to be grasped can be grasped with sufficient lateral balance. Therefore, there is an effect that the object to be grasped can be conveyed to a desired position with certainty, and its direction can be rotated in an appropriate direction. In particular, at the central portion of the lower end of the fixed portion, which is a main component of the present invention, an opening for mounting the base 6 of the semicircular claw-shaped bucket pieces 5 and 5 ', which are opposed to each other, is provided, and the bucket piece 5 is provided in the opening. Since the base 6 of 5'is rotatably inserted, not only is there an effect that the bucket pieces 5, 5'can be rotatably operated during use, but also the rotary bucket shown in FIGS. By removing the device and exchanging it with the direct excavation bucket shown in Fig. 3, you can excavate the direct excavation. There is.
