Description

The present invention relates to a bucket device for hydraulic heavy machinery such as a backhoe for the purpose of cleaning U-shaped grooves such as road gutters and agricultural land irrigation canals.

To remove mud and sand accumulated in U-shaped ditches such as road gutters and agricultural land irrigation canals, it was common to manually expose the bottom of the ditch, but in recent years, with the spread of hydraulic heavy machinery, the use of backhoes has increased. I came.

Japanese Unexamined Patent Publication No. 6-128981 Utility model registration No. 3144040 Jitsukaihei 7-2585 Gazette

Cleaning the U-shaped groove manually is laborious, but in order to remove the earth and sand of the U-shaped groove using a heavy machine such as a backhoe that is widely used, it is necessary to straddle the U-shaped groove due to the structure of the bucket mounting. I have to work. On the other hand, there are heavy machines that can offset the arm to the side of the car body, but it is not realistic to introduce an expensive special model for cleaning the U-shaped groove.

For example, Patent Document 1 proposes a bucket device in which a disk-shaped swivel structure portion is provided on an upper portion of a bucket, but the configuration of the swivel structure portion becomes complicated, and the swivel structure portion and a cylinder or an arm are provided. The connection with the superstructure is not disclosed.

Patent Document 2 discloses a invention of a hydraulic excavator in which each link between a bucket and an arm and a bucket and a cylinder is crossed, and the direction of the bucket is rotated by 90 degrees with respect to the traveling direction to suspend the excavator. However, since the direction of the bucket of the hydraulic excavator is fixed at 90 degrees with respect to the traveling direction, it is not possible to expose the bottom of the groove while advancing the heavy machine main body on the road, which is not efficient.

In Patent Document 3, one base is arranged between a bucket having a top plate and its superstructure, and the top plate of the bucket and the substrate are separated from each other so that the bucket can be swiveled with respect to the substrate. The invention of a gutter cleaning bucket having a structure pivotally attached by a shaft pin of a book is disclosed. However, as in Patent Document 1, the present invention does not mention the relationship with the cylinder and the arm when the bucket is swiveled, and it is said that it is impossible to suspend a heavy bucket with one shaft pin. I have no choice but to do it.

In view of the above problems, the present invention provides a bucket device for hydraulic heavy machinery that can efficiently clean the U-shaped groove by using a widely used hydraulic heavy machinery such as a backhoe by simply replacing parts. The task is to do.

In order to solve the above problems, the bucket device of the present invention is a bucket device for a hydraulic heavy machine, and is fixed to a hollow fixing bracket fixed to the arm tip of the hydraulic heavy machine and to be fitted inside the fixing bracket. An inner pipe that can be swiveled within a range, an attachment that is installed at the lower end of the inner pipe and has a shaft hole for suspending a bucket at the lower part, and a rotation mechanism at both ends, the upper end of which is the hydraulic heavy machine. It is characterized by comprising an operation rod connected to a bucket cylinder and suspending the bucket at the lower end, and the bucket suspended from the attachment and the operation rod.

A bolt is screwed to the side surface of the inner pipe, the fixing bracket has an elongated hole through which the bolt passes in the circumferential direction of the side surface, and the inner pipe is moved along the elongated hole of the fixing bracket. The inner pipe and the bucket are fixed at an arbitrary position by swiveling in the fixing bracket and interlocking the bucket in the horizontal direction and fastening the bolt at an arbitrary position.

The attachment has an upper shaft hole and a lower shaft hole capable of receiving two shafts in a right angle direction, the lower end of the inner pipe is pivotally attached to the upper shaft hole, and the bucket is shafted to the lower shaft hole. Once attached, the bucket is rotatably suspended in the vertical direction by the axial attachment mechanism.

The operation rod has a ball joint link mechanism provided with a box-shaped linkage as the rotation mechanism, and the ball portion at the tip of the operation rod is rotatably contained in the linkage, so that the linkage includes the ball portion. Horizontal and vertical movement of the suspended bucket is permitted.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to significantly reduce the labor required for the conventional heavy labor.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to clean a U-shaped groove at a low cost by simply replacing parts using a widely used hydraulic heavy machine such as a backhoe.

Due to the structure of this device, the bucket is put out parallel to the U-shaped groove from the side and can be freely adapted to some blurring, so that the work can be done safely without imposing a burden on the U-shaped groove.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the bucket device of the present embodiment (hereinafter, simply referred to as "this device"), the bucket is once removed from the link of the arm and the hydraulic cylinder of a general hydraulic heavy machine which is widely used such as a backhoe, and the bucket body is attached to the link. It is configured to install this device including this.

The specific configuration of this device is as shown in FIG.
First, the fixing bracket 3 is fixed to the link of the arm 1. The fixing bracket 3 is hollow inside and has an elongated hole 31 in the circumferential direction of the side surface (FIG. 3). Next, the inner pipe 4 is inserted into the fixing bracket 3 from below. The outer diameter of the inner pipe 4 is slightly smaller than the inner diameter of the bracket 3, and the inner pipe 4 can turn in the fixed bracket 3 in the circumferential direction. The inner pipe 4 has a bolt hole 41 having a female screwing process near the center of the side surface in the longitudinal direction (FIG. 4), and when the inner pipe 4 is inserted into the fixing bracket 3, the bolt hole 41 is the fixing bracket 3. Set the inner pipe 4 so that it can be seen through the elongated hole 31, and temporarily fix it from the outside with bolts 42.

Next, an attachment 5 for movably suspending the bucket 7 is pivotally attached to the lower end of the inner pipe 4. As shown in FIG. 5, the attachment 5 has an upper shaft hole 51 and a lower shaft hole 52, and can accept two shafts in a right-angled direction. As shown in FIG. 6, the upper shaft 53 pivotally attaches the lower end of the inner pipe 4, and the lower shaft 54 pivotally attaches the upper surface of the bucket 7. With this configuration, the bucket 7 can rotate back and forth and left and right.

On the other hand, an operation rod 6 having a rotation mechanism at both ends is installed between the bucket cylinder 2 and the bucket 7. As shown in FIG. 7, the operation rod 6 is provided with ball joint linkages 63 and 64, and is suspended from the linkage 63 by a configuration in which the ball portion 62 formed at the tip portion of the rod portion 61 is rotatably included. Horizontal and vertical movement of the bucket 7 is permitted.

FIG. 9 is a photograph of the backhoe equipped with this device for work. The inner pipe 4 in the fixed bracket 3 can turn left and right by 30 to 40 degrees, and by controlling the tilt of the front and back and left and right with the biaxial attachment part, the bucket 7 can be turned into a U-shaped groove from the diagonally extended arm. Can be put in parallel.
