JP3000851U - Universal grinder with left and right swing structure for excavator mounting - Google Patents

Abstract

(57) [Summary] [Purpose] To simplify the cleaning work of the formwork. [Structure] A universal grinder is attached to the tip of the excavator arm to clean the formwork in the vertical and horizontal directions from the operator's cab.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention enables cleaning work of concrete formwork in various construction civil works by attaching a brush to the rotary shaft. A drill can be used for concrete drilling, a whetstone can be used for polishing the formwork, and a disc saw can be used for mowing and excavator operation. And it is an attachment with a horizontal swing structure that can perform not only vertical work but also horizontal work with respect to the arm of the excavator.

[0002]

[Prior art]

 Conventionally, this type of work has a separate body for each work. Also, I was only able to work on the arm in the vertical direction.

[0003]

[Problems to be solved by the device]

 The former of the techniques described in the related art has a problem that it requires a great deal of effort to change the main body for each work, because a separate main body is required for each work.

Further, in the latter, there is a problem in that each work cannot be performed on the left and right inclined surfaces with respect to the arm of the excavator because the work can be performed only in the vertical direction on the arm.

The present invention has been made in view of the above problems of the conventional technique, and its object is to mow, punch, grind, and clean the work continuously with less labor. .

Further, each work is continuously performed not only in the vertical direction but also in the horizontal direction with respect to the arm.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the attachment of the present invention has a mechanism having a left-right swing structure that also serves as a mounting shaft for a disc saw blade, a drill, a grindstone, and a brush.

[0008]

[Action]

 The attachment of the present invention can continuously perform mowing, drilling, polishing, and cleaning work, and can work not only in the vertical direction with respect to the arm but also in the inclined surface in the horizontal direction.

【Example】

 Examples will be described with reference to the drawings. In FIG. 1, the head of the main body (6) has a bracket (1) and a bracket (2), and the bracket (2) swings left and right around a fulcrum pin (3) of the bracket (1), It can be fixed at any angle by tightening the nut (5) of the tightening pin (4). The main body (6) has a hydraulic motor (7) inside, and the rotary shaft (8) is connected to the rotary shaft. A wire brush (9) is connected to the rotating shaft (8).

In FIG. 3, the hydraulic power source of the excavator (12) is used to rotate the hydraulic motor (7) through the hydraulic hose (10) and the wire brush (9). To clean the mold (11).

In FIG. 4, the main body (6) swings left and right around the center pin (3) of the bracket (1) with respect to the excavator arm (13), and the tightening pin (4) is tightened. It can be fixed at any angle by attaching.

[0012]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

By operating the lever of the hydraulic source from the operator's cab of the excavator, the excavator arm can be easily cleaned in the vertical and horizontal directions.

Claims (1)

[Scope of utility model registration request] 1. An arm (13) centered on a fulcrum pin (3) on a bracket (1) which can be removably attached by a pin at the tip of an arm (13) of an excavator (12).
On the other hand, the bracket (2) is swingable in the left-right direction and can be fixed at an arbitrary angle by tightening the nut (5) of the tightening pin (4). The bracket (2) is provided with a main body (6) for rotating a rotary shaft (8) via a rotary actuator (7), and a disc saw blade, a drill, a grindstone, and a brush are attached to the rotary shaft (8). This is an attachment that can perform cutting, drilling, polishing, and cleaning work.
