Description

DETAILED DESCRIPTION OF THE INVENTION The invention of this application relates to a bucket device for scooping up dirt and sand. Conventionally, when scooping earth and sand using a bucket device for scooping earth and sand, in shovel-type excavators, only one bucket is rotated from below to above around a horizontal pivot shaft. It has been done to scoop out the soil by letting it slide. However, when there were relatively large rocks stuck in the soil, it was difficult to scoop them out with just one bucket.

The invention of this application aims to eliminate the above-mentioned drawbacks.

Next, the configuration for achieving the above purpose will be explained according to the drawings.
1' and an opening/closing bucket 2' are arranged facing each other, and both buckets 2, 2'
In this earth and sand scooping device, a gear shaft 4 is disposed coaxially and directly connected to a hydraulic motor 5 at a pivot point of a bucket main body 2, and the gear shaft 4 A mounting plate 7 is provided at the connection between the and the hydraulic motor 5, bolt fixing holes 9 are provided at the four corners of the frame of the mounting plate 7, and fixing bolts 8 are inserted into the bolt fixing holes 9. The hydraulic motor 5 is fixed to the main bucket 2 by tightening the bolts to the main bucket 2, and the hydraulic motor 5 is installed in the lower part of the space formed between the main bucket supports protruding from the upper part of the main bucket 2 facing each other. A gear shaft 4 protruding coaxially from the motor 5 is disposed, and the gear shaft is inserted into an opening formed by an internal gear 6 provided above the opening/closing bucket 2', and the external gear of the gear shaft 4 and the The main bucket 2 and the opening/closing bucket 2' are rotated around the gear shaft 4 by meshing with the internal gear 6, so that the bucket 2 and the opening/closing bucket 2' can be opened and closed with each other. A blind plate 3 for the main bucket and a blind plate 3' for the opening/closing bucket are provided on both side walls, respectively.
This is a bucket for scooping up soil and sand.

Next, the effect resulting from the above configuration is that when the hydraulic motor is driven to rotate the gear shaft, the opening having the internal gear 6 meshed with the gear can be rotated to open and close the opposing bucket. .

The effects resulting from the above configuration include arranging the main bucket 2 and the opening/closing bucket 2' facing each other, which have pin holes 1 and 1' at appropriate positions above them;
Since the earth and sand scooping device has both bucket carts 2 and 2' that can be opened and closed in opposing positions, it has the advantage that it can be easily attached to or removed from a power shovel or the like. Further, a gear shaft 4 coaxially protruding from the hydraulic motor 5 is disposed below the space formed between the main bucket support parts that protrude from the upper part of the main bucket 2, and the gear shaft 4 is connected to the hydraulic motor 5. The main bucket 2 and the opening/closing bucket 2' are inserted into an opening formed by an internal gear 6 provided above the opening/closing bucket 2', and the external gear of the gear shaft 4 meshes with the internal gear 6. The gear shaft 4
The hydraulic motor is located in the structurally strong main bucket, and an internal gear is installed in the opening/closing part, which is slightly weaker than the main bucket. This has the effect of making the internal gear more durable due to its nature. In addition, a gear shaft 4 is disposed coaxially and directly connected to the hydraulic motor 5 at a pivot point of the main body bucket 2, and the gear shaft 4
A mounting plate 7 is attached to the connection part between the and hydraulic motor 5.
, bolt fixing holes 9 are provided at the four corners of the frame of the mounting plate 7, and bolt fixing holes 9 are provided at the four corners of the frame of the mounting plate 7.
The hydraulic motor 5 is fixed to the main body bucket 2 by inserting the fixing bolt 8 into the main body bucket 2 and tightening the bolt to the main body bucket 2. This has the effect that the hydraulic motor can be easily removed from or attached to the main body bucket 2. be. Furthermore, since a mounting plate is provided at the connection between the gear shaft and the hydraulic motor, there is no risk of any problems in terms of strength. In addition, since this is a bucket for scooping earth and sand, a blind board 3 for the main bucket and a blind board 3' for the open and close bucket are provided on both side walls of the main bucket 2 and the opening/closing bucket 2', respectively. Not only can the work be done easily, but even if there are relatively large rocks stuck in the earth and sand, these rocks can be scooped out together with the earth and sand. In addition, the surface of the gear shaft connected to the hydraulic motor and the surface of the opening made of the internal gear provided on the opening/closing bucket side are likely to be subject to significant wear and tear during use, so these parts should be replaced with the surrounding parts or connecting parts. By making it possible to make and replace the bucket separately, it has the effect of extending the life of the bucket as a whole.
