Description

  This invention relates to the function of a bucket of a power shovel.

As the work environment in construction work, the aging of workers, the shortage of skilled and young workers, rising labor costs, etc. are progressing on the condition that there are many outdoor environments and the natural environment is severe. In order to compensate for this, the frequency of using the excavator for various operations other than excavation has increased, and contact between the heavy equipment and the heavy equipment due to the work close to the power excavator in a narrow work space Various occupational accidents related to power shovels, such as falling, are increasing.
In terms of construction quality as well, in the manual excavation work by an operator using an excavator, the ground on the construction base surface tends to be roughened by overexcavation. On the other hand, if the base surface is finished with a power shovel, the construction accuracy is deteriorated because it is performed with a standard bucket with a tooth.
Thus, since heavy machinery is used up to the field of workers, the use time of inefficient excavators tends to increase.
In recent years, attachments with special functions that have improved excavator buckets, primarily intended for excavation and loading of earth and sand, have come to be seen. Examples of these include a bucket front portion having a pinching function, a hydraulic clam shell, a hydraulic ready concrete placing hopper, a material collecting clamp, and an attachment for loading and unloading concrete secondary products.

However, although the above bucket has a special function, there is no single bucket having a more versatile usage.
Therefore, the present invention adds a grip work to the excavator, which improves work accuracy, prevents contact accidents between heavy machinery and workers, and reduces the work cost by reducing the number of workers. A multifunction bucket of a power shovel is provided.

In order to solve the above problems, the bucket of the excavator has a two-part structure of a fixed portion inner bucket having a digging surface plane edge structure and a rotating portion outer bucket having a digging tooth and a side cutter. These inner and outer bucket joints have a pin structure, and two hydraulic cylinders are installed on the back surface of the fixed part inner bucket, thereby adding grip work by opening and closing the bucket.
The shape of the bucket body is the same as that of a conventional bucket dedicated to excavation, and is a multifunction bucket of a power shovel that can be switched between an excavator function and a hoe function by reverse mounting the bucket.

  The hydraulic oil is supplied to the bucket cylinder by using the combined piping of the power shovel arm, and the bucket is opened and closed using a combined piping lever at the driver's seat.

The following usage effects can be expected.
(1) Since the bucket shape is the same as that of the conventional bucket, as shown in FIG. 2, it can be used as a standard bucket with the tooth 18 and the side cutter 17 during excavation, and heavy excavation is possible. In addition, by exchanging the bucket, both excavator and backhoe operations can be performed.
(2) At the time of construction base surface finishing, as shown in Fig. 3, by using the bucket opening and closing function, the outer bucket a is opened and the flat edge 4 of the inner bucket b is used, so that the accuracy of the ground surface is not roughened. A good finish.
(3) A crumb work function as shown in FIG. 4 is added. With this function, extra pits such as pit excavation and dredging can be prevented. Moreover, bottom discharge and loading in a narrow place are possible.
(4) As shown in Fig.-5, you can grab, spread, spread, and level the aggregate. Further, by adjusting the opening / closing amount of the bucket, it is possible to start spreading while finely adjusting the spraying amount, and furthermore, it is possible to finish leveling at the planar edge of the inner bucket.
(5) As shown in FIG. 6, it can be used as a substitute for a raw cooker hopper, and can be placed while finely adjusting the discharge amount by the opening and closing function of the bucket. Since the concrete placement work can be performed by operating the driver's seat of the excavator, the number of workers can be reduced.
(6) As shown in FIG. 7, it is possible to grip various materials such as wood, steel, and pipe.
(7) Using the attachment steel rod d using the perforated portion c of the inner and outer bucket side portions, it can be used for installing, moving and organizing products as shown in FIG.
(8) Crushing / disassembling of wooden structures, felling processing, stacking of waste materials and loading work using the opening / closing grip function of the bucket are possible.
(9) Since there is no hanging load with wires etc., there is little danger and the travel time is fast.

Hereinafter, the structure of the present invention will be described in detail with reference to FIG. FIG. 1 is a rear view and a side view of the bucket.
The bucket is composed of a fixed portion inner bucket composed of a side plate 3, a bottom plate 5, and a bottom plate 4 with an edge for excavation, a side plate 1, a side cutter 17, a tooth 18 for excavation, a bottom plate 2 with an edge, and a reinforcing bracket 6. Divided into outer rotating buckets.

  These buckets are pin-coupled by a rotating shaft pin 14, and both buckets have a structure that can rotate around the rotating shaft pin 14. The rotating shaft pin 14 is connected to the rod side of the hydraulic cylinder 11 by the rotating pin 13 through the bracket 7. The bottom side of the hydraulic cylinder 11 is coupled to the fixed portion inner bucket by a bracket 8 by a rotary shaft pin 12.

  With the above structure, the rotating portion outer bucket is opened and closed around the rotating shaft pin 14 via the bracket 7 by the expansion and contraction of the hydraulic cylinder 11.

  As shown in FIG. 9, the existing combined pipe e is diverted to the hydraulic cylinder 11, the hydraulic oil is supplied by the hydraulic hose f, and the bucket is opened and closed.

  Further, when the bucket is closed, the rotation portion outer bucket is prevented from rotating by the inner / outer bucket fixed shaft steel bar 15.
