Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket device used for scooping sand on a beach to collect dust.

[0002]

2. Description of the Related Art Conventionally, as a bucket device of this type,
For example, the structure shown in Japanese Utility Model Publication No. 62-89340 is provided. This conventional bucket device is composed of a container-shaped bucket main body having one opening, and a bucket lid body provided in the bucket main body capable of opening and closing the opening and having a large number of through holes.

According to this conventional configuration, the bucket body is scooped of sand while the bucket lid body is opened, and the bucket lid body is closed. Only sand is dropped from the area to collect dust.

[0004]

However, according to the above-mentioned conventional structure, when the through hole is small, the through hole is easily clogged with a particularly large dust, and when the through hole is large, the small dust causes the through hole to be blocked. It will pass and fall with the sand. Further, the passage condition through the through-hole changes depending on the property (particle size, etc.) and state (dry and wet, etc.) of the sand.

In view of the above, an object of the present invention is to provide a bucket device capable of selecting and collecting large dust particles and small dust particles.

[0006]

In order to achieve the above-mentioned object, a bucket device according to a first aspect of the present invention is a bucket main body which can be attached to a boom from the vehicle side, and an opening of the bucket main body. And a bucket lid body that can be opened and closed, and a core body that is provided between the bucket body and the bucket lid body and that is movable in the opening and closing direction. The core body has a large number of through-holes that are larger than the through-holes of the bucket body.

Therefore, according to the first aspect of the invention, the bucket lid body is rotated to open the opening of the bucket body, and the bucket body is grounded while the core body is rotated toward the bucket body side. By moving it forward, it is possible to scoop sand. After scooping sand etc., rotate the bucket lid downward to close the opening of the bucket body, and lift the bucket device.
The bucket device side can perform a sieving action, so that sand or the like can be discharged to the outside through the large penetrating portion of the core body and the small penetrating portion of the bucket body.

Further, since large dust contained in sand cannot pass through the large penetrating portion, it can be collected by the core body and does not move to the bucket body side. The small dust that has passed through the large penetrating portion cannot be passed through the small penetrating portion and therefore can be collected by the bucket body and is not discharged to the outside. At that time, by rotating the core body toward the bucket lid side, it is possible to promote the selective collection of dust. Even when the scooping is advanced, the sand can be discharged to the outside and dust can be selectively collected.

When such a selective collection is carried out and the amount of collected dust is small, the work of scooping sand or the like may be carried out again. Also, when there is a large amount of dust collected,
The bucket device is transported in a lifted state, and then loaded (discharged / loaded) on another transport vehicle.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.
Description will be made based on the drawings. For example, a bucket device 10 attached to the free end side of a boom 1 that is vertically swingably provided on the side of an industrial vehicle (not shown) includes a bucket body 11 that can be attached to the boom 1 and the bucket body 11. The opening is opened and closed by a bucket lid body 18, a core body 25 provided between the bucket body 11 and the bucket lid body 18 and movable in the opening and closing direction, and the like.

The bucket body 11 includes a bottom seat portion 12
And side plate portions 13 on both sides, and a blade 14 is integrally provided at the front end of the bottom sheet portion 12. The bottom sheet portion 12 is configured in a grid shape by arranging a large number of grid members 15 in a row in the left-right direction (vehicle width direction). The penetrating portion 16 is formed.

The bucket body 11 having the above structure is
The side plate portion 13 is connected to the boom 1 via the horizontal pin 2, so that the side plate portion 13 is rotatably attached to the boom 1 side. A push rod 3 for rotating the bucket body 11 is connected to the bucket body 11 side. The free end side of the push rod 3 is interlocked with the tilting cylinder (neither is shown) side via a bell crank or the like.

The bucket lid 18 is a window frame-shaped outer frame 19
And a net body 20 stretched over the outer frame body 19 and the like. Then, the bucket lid body 18 is rotatably moved to the bucket body 11 side by the outer frame body 19 being connected to the side plate portion 13 of the bucket body 11 via the lateral pin 21, that is,
The opening of the bucket body 11 is attached so as to be openable and closable. Further, an opening / closing cylinder 22 for rotating the bucket lid 18 is provided between the bucket body 11 and the bucket lid 18.

The core body 25 is composed of a left and right connecting member 26 located on the inner side, and a grid member 27 having a base end connected to the connecting member 26 and a free end extending forward. Then, a large number of grid members 27 are arranged side by side in the left-right direction to form a grid, and thus the gaps in the left-right direction of the grid members 27
A large number (wide width) of wide penetrating portions 28 are formed with respect to the narrow penetrating portion 16 of the bucket body 11.

The core member 25 thus constructed is attached to the bucket body 11 side so as to be rotatable in the opening / closing direction by connecting the connecting member 26 to the bucket body 11 side via the horizontal pin 29. To be A rotating cylinder 30 for rotating the core body 25 is provided between the bucket body 11 and the core body 25.

The net 20 in the bucket lid 18
The mesh (penetrating portion) 23 is made finer than the wide penetrating portion 28 of the core body 25. The core body 25 is the bucket lid body 18.
When rotated to the side, the free end of the grid member 27 group is
It is configured to project upward through the mesh 23 of.

The operation of the above embodiment will be described below. As shown in FIG. 1, the contraction of the opening / closing cylinder 22 causes the bucket lid 18 to rotate upward to open the opening of the bucket body 18, and the rotation cylinder 30.
The core body 25 is rotated downward by the contraction of the boom body 1 and the free end thereof is brought into contact with the bottom seat 12 side of the bucket body 11, and the boom 1 is swung downward as shown in FIG. Then, the bucket body 11 is grounded.

In this state, the bucket device 10 is moved forward by traveling of the vehicle so that the sand A or the like can be scooped. When the scooping is advanced, a part or most of the sand A passes through the wide penetrating portion 28 of the core body 25 and the narrow penetrating portion 16 of the bucket body 11 to the rear of the bucket device 10, that is, the outside. Is discharged to. Further, the large dust B contained in the sand A cannot be passed through the wide penetrating portion 28 and is therefore collected by the core body 25, so that it does not move to the bucket body 11 side, and thus the narrow penetrating portion 16 is large. Dust B will not clog. Furthermore, since the small dust particles C that have passed through the wide penetration portion 28 cannot pass through the narrow penetration portion 16, the bucket main body
It is collected in 11, so small dust particles C are not discharged to the outside.

All the sand A and small dust particles C do not pass through the wide penetrating portion 28, but gradually collect in the bucket body 11. At this time, the bucket lid 18 is rotated downward by the extension of the opening / closing cylinder 22 to move the bucket body 11
The opening is closed, and the boom 1 is further swung upward to lift the bucket device 10 as shown in FIG.

In this state, for example, by expanding and contracting the tilting cylinder, the bucket device 10 is rotated via the push rod 3 and the like, and the bucket device 10 is shaken to perform a sieving action. Therefore, most of the sand A passes through the wide penetrating portion 28 of the core body 25 and the narrow penetrating portion 16 of the bucket body 11 and is discharged below the bucket device 10. Also, the large dust B is collected by the core 25,
The smaller dust particles C are collected in the bucket body 11. At that time, the core body 25 is rotated upward by the extension of the rotation cylinder 30, so that the sorting and collection of the dusts B and C can be promoted.

When the amount of collected dusts B and C is small during such selective collection, the work of scooping sand A or the like may be performed again as shown in FIG. Dust B,
When a large amount of C is collected, the bucket device 10 is transported while being lifted, and as shown in FIG. 2, the bucket lid 18 is opened to load it onto another transportation vehicle. (Discharge / input) is performed.

In the above-described embodiment, the sand A is scooped to selectively collect the dust B and C, but this includes earth and sand and the like. The dust B and C also include stones and the like.

In the above-described embodiment, the slit-shaped narrow through-hole 16 or the wide through-hole 28 is shown as the through-hole, but this may be a through-hole type or a mesh type. In the above-described embodiment, the net body 20 is attached to the bucket lid body 18.
According to this, the weight can be reduced, but the plate structure may be used instead of the net structure. The mesh 23 of the mesh 20 may have any size.

[0024]

According to claim 1 of the present invention described above, by scooping sand or the like, closing the opening of the bucket main body with the bucket lid, and then lifting, the bucket device side can perform the sieving action, Thus, sand or the like can be discharged to the outside through the large penetration part of the core and the small penetration part of the bucket body. In addition, since large dust cannot pass through the large penetrating portion, it can be collected by the core body. As a result, it does not move to the bucket body side, so that the small penetrating portion can be prevented from being blocked by the large dust. Then, the small dust that has passed through the large penetrating portion cannot be passed through the small penetrating portion, so that it can be collected by the bucket body, thereby preventing the small dust from being discharged to the outside. Therefore, regardless of the properties (particle size, etc.) or state (dryness, etc.) of sand or the like, it is possible to always favorably select and collect dust.
