Description

[Detailed description of the device]

[0001]

[Industrial applications]

 Various types of power shovel attachments are developed and marketed according to the work purpose, but even if the usage is a little different, it is often necessary to replace another attachment, which requires time, labor, maintenance, and maintenance. Processes occur, and problems that cannot be ignored economically arise. In order to solve these problems, a dual-purpose bucket was devised in order to achieve more than one work purpose with a single attachment to save labor and improve work efficiency.

[0002]

[Prior Art]

 Conventionally used power shovel buckets are used when sorting concrete buckets and rubble that are left in the soil from normal buckets that are used when loading dump trucks and during excavation work, or at the demolition site. It can be roughly divided into sorting buckets, commonly called skeleton buckets, that are used for particle size classification of the split concrete waste.

[0003]

[Problems to be solved by the device]

 Therefore, it is necessary to provide two buckets depending on the application, which causes the trouble of replacement, damage to the mounting pins and bolts, loss such as damage and loss, and transfer from site to site. At the same time, an increase in extra baggage will increase various operations in terms of maintenance and management of heavy equipment. In view of these points, the present invention has a structure in which a single bucket can be used for excavation and loading work as well as sorting work with a simple structural change.

[0004]

[Means for Solving the Problems]

 As described above, in the present invention, one bucket is used for both excavation work and sieving work, so that a bottom plate having a required thickness is installed in the lattice part of the bottom of the bucket, and the earth and sand falling inside the bucket drops during the work. It is used for excavation and loading work by blocking it so that when the next sieving work is performed, the fixing bolts on the bottom plate are removed and moved to the back plate or the side plate by the method and fixed and used.

[0005]

[Action]

 As described in the previous section, the action is to move the bottom plate to change the action and effect according to the application.

[0006]

【Example】

 The operation and effects of this system will be described below with reference to the drawings. Fig. 1 shows a side sectional view of a bucket body. The bucket body is roughly classified into two side plates, two left and right sides, and a bottom plate. 1, 8 and the rear plate 3 are flat and curved, respectively, and each plate is welded to form a main body, and the teeth 4, side cutter 5, arm mounting flange 12, etc., which are accessory parts, are joined to it. Buckets are formed.

The moving bottom plate 1 in FIG. 1 is fixed to the fixing flange 6, the bottom plate 8 and the vertical member 9 and fixed by the fixing bolts 7a. In this state, a normal bucket operation, that is, excavation, It is used for loading work.

As shown in the plan view of FIG. 3, the vertical member 9 is joined to the horizontal member 12 in a lattice shape to form a mesh.

Next, when performing a sorting operation, the state shown in FIG. 2 is used. To change from FIG. 1 to FIG. 2, the bucket is attached to the arm of the power shovel in the state shown in FIG. Remove the fixing bolt 7a in the attached state, and the operator in the driver's seat starts the engine and lifts the tooth 4 side while operating the lever. At that time, lightly vibrate the bucket body with the lever operation. Then, the moving bottom plate 1 slides down to the rear plate 3 side, stops at the position of the fixed guide 11 at the end and is fixed by the fixing bolt 7b, and the change to the sorting bucket in FIG. 2 is completed.

At this time, since the moving bottom plate is supported by the guides 10a and 10b, it does not drop or come off from the bucket body.

The above is the configuration of the basic operation in this method, but in order to improve the work efficiency in the sorting work, it is obvious that the larger the grid-like area in a bucket of a certain size, the better. The area in contact with the residual soil, which requires gravel, becomes wider, and the time for debris removal becomes faster and the work efficiency improves. Therefore, naturally there is a limit to the expansion of the grid-shaped area, so there is no choice but to expand it toward the rear plate. However, a storage space for the moving bottom plate must be secured in the rear plate.

Therefore, as shown in FIG. 4, by providing a hinge 13 in the middle of the movable bottom plate and bending it in the direction of the arrow, the area of the movable bottom plate can be halved as shown in FIG. .. As a result, the grid-like area can be expanded by that much, thus improving work efficiency.

FIG. 6 is a diagram in which the curved surface portion of the curved surface of FIG. 5 is changed to a flat plate, and the storage at the rear plate portion of the bucket is completely adhered to prevent the residual soil from entering. ..

Further, FIG. 8 has an advantage that the moving bottom plate can be smoothly stored by the method of bending the rear side of the moving bottom plate to the front side as shown by the arrow, contrary to FIG.

By increasing the number of moving bottom plates from one to two in this way, the area can be halved, but it is also possible to increase the number of hinges to increase the number of bottom plates to three or four. Is.

FIG. 9 is a step far from the concept that has been described as an embodiment, and as shown in the figure, the central portion of the bottom plate is cut into two pieces on the left and right, and hinges are attached to both outer bases of the bottom plate. It is a double-door type and is fixed to the bucket side plate to put it in the state of the sorting bucket.

FIG. 7 shows a structure in which FIG. 9 is further developed and a front bottom plate 16 and a rear bottom plate 15 are additionally provided, and a hinge 13 is attached to each bottom plate to form a three-way open form.

[0018]

[Effect of the device]

 The present invention is configured as described above, but has the following effects. Since one bucket can be used for both sieving work, loading work and excavation work, efficiency can be improved economically and timely. The work can be done easily because the structure can be changed easily, and labor is saved.
