[Means for Solving the Problems and Effects of the Invention]
In order to achieve the above object, according to the first aspect of the present invention, a container-like bucket body having an opening for storing and discharging a transported object is provided on the working device so as to be movable up and down and vertically rotatable. In the bucket device, a plurality of through holes for supplying air are provided in the vicinity of the bottom corner of the bucket body, and the through holes are caused by the external force from the contents moving when the conveyed product is stored in the bucket body. While closing a through-hole, the opening of a bucket main body is faced down, and the movable plate which opens the said through-hole at the time of discharge of a conveyed product and supplies air is provided .
[0007]
In the above configuration, since a plurality of air supply through holes are provided in the vicinity of the bottom corner of the bucket main body where sediment such as earth and sand is easily deposited, the bucket main body is put into a dumped state and operated to knock the bucket main body. When vibration is applied to air, air enters between the earth and sand and the bottom of the bucket body from the air supply through- hole, so that the earth and sand are easily separated from the bottom of the bucket body, and the unloading is improved. If this bucket apparatus is used, an efficient operation | work can be performed with respect to a conveyance thing with stickiness like red clay or clay. Moreover, in the above configuration, since the movable plate that closes the through hole when the conveyed product is stored and opens the through hole when the conveyed product is discharged to supply the air is provided, it can be used for sticky conveyed items such as red clay and clay. In addition to being able to work efficiently, granular materials such as gravel are not spilled from the through hole, and can handle a wide variety of conveyed items.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a bucket device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a usage state of the bucket device 1. The bucket apparatus 1 is configured to move a bucket body 10 that is an object storage container having an opening 4 for scooping or discharging a conveyed object such as earth and sand, a work boom 11 that moves up and down while supporting the bucket body 10, and a bucket body 10. It consists of a hydraulic cylinder (not shown) for moving. The work boom 11 that supports the bucket body 10 is provided, for example, at the front of the vehicle body of the wheel loader 2 that is a work device. The bucket device 1 moves together with the wheel loader 2, and the bucket body 10 is moved up and down and turned up and down by power and control from the wheel loader 2.
[0011]
A series of movements of cargo handling work using the bucket device 1 will be described. The bucket body 10 moves forward (moves in the left direction) in the state of position A, scoops the conveyed product on the ground from the front opening 4, and is rotated upward to the position B as indicated by an arrow 12. . Next, the bucket body 10 rises as the work boom 11 rises to the position C as shown by an arrow 13 in this posture, and discharges, for example, clay 101, which is a conveyed product, from the opening 4 toward the dump truck bed. Therefore, it moves by the movement of the wheel loader 2 and is rotated downward as indicated by the arrow 14 to be in the position D. The bucket body 10 performs an up-and-down rotation operation (happing operation) in order to promote the unloading of the clay 101 at the position D.
[0012]
The structure provided in the bucket main body 10 in order to improve the unloading at the time of discharge will be described. 2 shows the bucket body 10, FIG. 3 (a) shows the back surface of the bucket body 10, and FIG. 3 (b) shows a cross section in the short direction.
