[Industrial applications]

 The invention of this application relates to a gear actuated bucket device for scooping earth and sand.

[0002]

[Prior art]

 Conventionally, when excavating earth and sand using a bucket device for earth and sand scooping, generally, in excavator type excavators, one bucket with an opening above it was used to scavenge earth and sand, but without a lid. It is inconvenient to scoop off the soil at a relatively low position from the position of the excavator, and in the worst case, there is a drawback that it cannot be scooped.

[0003]

[Problems to be solved by the device]

 The invention of this application aims at eliminating the above-mentioned drawbacks. Further, as described above, the next object of the present invention is to mount a conventional bucket without a lid on the tip of a general excavator and operate it, especially when looking at the position of the excavator, the soil at a relatively low position is removed. Since it was inconvenient to scoop up, an improvement measure was necessary, but the technique described in Japanese Patent Laid-Open No. 21503/1975 was developed as an improvement measure. The technique is a conventional power shovel. The bucket opening has a backrest that is approximately the same size as the opening.The backrest has a flat box shape with the bucket side opening, and the soil excavated by the bucket is stored in the bucket. After closing the backrest, there is no risk of spilling the stored sand even if the bucket's list angle is large, and the rock mass to be loaded is backfilled. Even if it is larger than the width of the bucket, it can be safely and swiftly loaded even if it is the largest by holding it between the bucket and the backrest and lifting it together with the bucket. The backrest allows the bucket and the backrest to be actuated by hydraulic cylinders and the contents such as dirt and sand contained in the bucket not to be spilled to the outside. The opening can be simply capped, and it only serves as a cap and does not function as a bucket at all. Therefore, there is a drawback that the processing amount can be increased by about 10% as compared with the processing amount by the bucket of the conventional general power shovel. In addition, since the backrest is flat, an increase in the throughput cannot be expected, and even if the rock mass is clamped, it will be pressed by the flat part of the backrest and clamped. Some of them had a drawback that they could not be reliably clamped. Also, since the tip of the handle arm is used as the pivot point of the bucket and the backrest, that section becomes a single pivot point, and it is impossible for a child to install a rotary drive source at that section. Instead, the backrest had the drawback of activating the backrest cylinder. The present invention is intended to eliminate the above-mentioned drawbacks of the bucket device for a construction machine described in Japanese Patent Application Laid-Open No. 50-21503.

[Means for Solving the Problems]

 Next, a specific configuration for achieving the above-mentioned object will be described with reference to the drawings. It has pin holes 1 and 1'at appropriate positions of the opposing standing wing pieces above the main bucket, and the pin holes 1 and 1'are provided behind the main bucket. The main body bucket 2 and the opening / closing bucket 2'having a curved surface facing each other are arranged so as to face each other, and both buckets 2 and 2'are pivotally supported by the opening / closing bucket pivot pin 7, A large gear 3 integrally formed with the opening / closing bucket 2'is arranged around the pivot pin 7 in order to rotate each other with respect to each other by using the opening / closing bucket pivot pin 7 as a pivot shaft. The small gear 3 is arranged at an appropriate position in the center of the opposed standing wing piece formed on the upper portion of the main body bucket 2 so as to mesh with the shaped gear 3, and the pivot pin 8 of the small gear 3 and the main body bucket 2 are provided. A hydraulic motor or electric The drive shaft of the motor 4 is directly connected, the hydraulic motor 4 is fixed inside the main body bucket by a fixing device such as a motor fixing bolt 6, and the main body is attached to the side wall surface portions of the main body bucket 2 and the opening / closing bucket 2 '. A gear-operated bucket device for scooping earth and sand, which is provided with a bucket blind plate 5 and an opening / closing bucket blind plate 5 '. It should be noted that the cushion rubbers 11 and 11 'may be provided on the blind plates 5 and 5'at their peripheral portions facing each other.

[0005]

[Action]

 Next, to describe the function and effect resulting from the above configuration, in order to scoop up the earth and sand with the earth and sand scooping bucket device of the present invention, the electric motor or the hydraulic motor 4 fixed in the main body bucket is started to drive the motor. The small gear 3 connected to the shaft by a shaft is rotated clockwise in the figure, and the large gear 3 ′ meshing with the small gear 3 is rotated to connect the main body bucket 2 and the open / close bucket 2 ′ to the open / close bucket. It is possible to open each other around the pivot pin 7 so that the soil can be scooped out.

[0006]

【effect】

 Therefore, by rotating the small gear 3 in the counterclockwise direction by reversing the motor or by another method, the opening / closing bucket is rotated in the closing direction with respect to the main body bucket, and finally the opposing bucket. There is an effect that can be completely closed. Further, since the large gear 3'on the opening and closing bucket side has a larger diameter than the small gear 3 on the main body bucket side, the structure of the gear type speed reduction mechanism allows the bucket to be opened and closed, which is large even with a relatively small power motor. Since the force can be transmitted, it is possible to reliably grab and carry relatively heavy soil or rock. By disposing the cushion rubbers 11 and 11 'on the peripheral portions of the main body bucket baffle plate and the open / close bucket baffle plate which are opposed to each other, there is an effect that the peripheral portions that are easily damaged can be made less likely to be damaged. Further, the main body bucket and the opening / closing bucket are arranged so as to face each other, and both of these buckets form a curved surface toward the rear so that the two opposing buckets operate from the open state to the closed state. A large amount of earth and sand can be reliably stored in the curved concave part inside the bucket, and even if a rock mass is sandwiched, it is strong in a state where it is close to the butted state of the bucket together with the wide space of the curved concave part. It is possible to reliably prevent the contents in the bucket from falling off due to the clamping force. In addition, by directly connecting the pivot pin of the small gear and the drive shaft of the drive source of the hydraulic motor or electric motor provided in the opposed standing wing pieces formed on the upper part of the main body bucket, they are located side by side in the upper part of the main body bucket. A drive source such as a hydraulic motor or an electric motor disposed in the opposed upright blades drives a small gear as necessary regardless of the main body bucket, and the small gear operates a large gear that meshes with the gear. Since the opening / closing bucket integrally formed with the large gear can be opened / closed as desired, there is an effect that the opening / closing bucket can be opened / closed very lightly and reliably with respect to the main body bucket. In particular, even in the relatively narrow space between the opposing standing blades formed in the upper part of the main body bucket, the small gear can be driven by the relatively small drive entrance, so that the small gear can be driven against the large gear that moves the opening / closing bucket. There is an effect that the side of can be made compact. In addition, the pin holes 1 and 1'are provided at appropriate positions above the opposed upright wing pieces to attach the other end of the bucket opening / closing link mechanism in which one end is attached to the tip of the arm of the conventional power shovel. There is also an effect that it can be attached to the holes 1 and 1'and operated without any trouble.
