Description

[Detailed explanation of the idea] The present invention relates to an improvement of a bucket loader.

Conventionally, a bucket loader has a structure in which the bucket is supported by a single support shaft fixed above the bucket via an arm, and the bucket is tilted using this support shaft as a fulcrum to discharge stored items. When trying to drain the stored items, the stored items often flow out before the tip of the bucket reaches the container's inlet and fall outside the container instead of entering the inlet. There were problems such as the need for a large space for tilting.

The present invention has been made with the aim of solving the above problems, and one embodiment of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a base made by connecting two cross-shaped members arranged on the left and right with an interval such that a bucket bag 8, which will be described later, can enter by tilting. Two bearings 2, 2 are fixed at a required interval on the left and right, and the bearings 2, 2 are
A first support shaft 3 is mounted between them. and,
Links 4, 4 are fixed to both left and right ends of the first support shaft 3, bearings 5, 5 are provided at the tips of the links 4, 4, respectively, and a link is provided at the upper part of the middle position of the links 4, 4. Contact portions 4a, 4a are formed, respectively, for determining the end position of the rotations of 4, 4. Further, as shown in FIG. 2, a second support shaft 6 is mounted between the bearings 5, 5, and one ends of arms 7, 7 are fixed to both left and right sides of the second support shaft 6.
The other ends of the arms 7, 7 are fixed to the upper position of a bucket 8, which is placed facing upward on the left foundation of the base 1 as shown in FIG.
Rollers 9, 9 which rotate in the vertical direction are pivoted on both left and right sides of an intermediate position of the base 1 through brackets 10, 10, and the rollers 9, 9 are attached to rails 11, 11. In addition, pulleys 12, 12 are installed on both left and right sides of the lower position of the bucket 8.
Wire ropes 13, 13 from a hoisting device (not shown) fixedly disposed above the base 1 are hung on the base 1.

Next, a description will be given of the operation when the device configured as described above is used, for example, to feed a product into the rotating drum D of a rotating drum type shot blasting device. After loading the product to be shot blasted into the bucket 8 by an appropriate conventional means (not shown), a hoisting device (not shown) is driven to wind up the wire rope 13. is lifted up via pulleys 12, 12, guided and supported by rollers 9, 9 and rails 11, 11, and moved upward, and at the same time, links 4, 4 are moved upwardly by first support shaft 3.
It is rotated clockwise in FIG. 1 using the fulcrum as the fulcrum. As the links 4, 4 rotate, the bucket 8 begins to tilt to the right using the rollers 9, 9 as fulcrums, and the contact portions 4a, 4a of the links 4, 4 contact the base 1, causing the links 4, 4 to rotate. When the rotation stops, the bucket 8 is
As shown by the dotted chain line, the discharge port advances to the right and faces the opening at the tip of the rotating drum D, and is in a substantially horizontal state. At this time, normal products do not flow out from inside the bucket 8. After this, wire rope 1
3 and 13 continue, and after the links 4 and 4 stop rotating, the bucket 8 is further tilted and rotated clockwise about the second support shaft 6, and the products inside the bucket 8 are It flows down into the rotating drum D,
It is reliably supplied into the rotating drum D without falling outside the rotating drum D. After supplying the product, the hoisting device is reversely driven to loosen the wire ropes 13, 13, and the bucket belt 8 rotates counterclockwise around the second support shaft 6, and then, together with the bucket belt 8, the link 4, 4 also rotate counterclockwise, and after the rollers 9, 9 contact the rails 11, 11, the bucket 8 descends along the rails 11, 11, and the entire process is completed.

As is clear from the above description, the present invention supports a bucket with a link that is fixedly arranged to be rotatable in a vertical plane and an arm that is rotatably connected to the link, so that it can be tilted and rotated. Because it is configured so that it is possible,
By simply lifting the lower part of the bucket, the outlet of the bucket can be advanced into the input port of the container, and
It is now possible to rotate the bucket to a large extent, allowing stored items to be reliably fed into the container without causing them to fall outside.Furthermore, the radius of rotation of the bucket is reduced, making it possible to It has excellent practical effects, such as the space required for rotation being much smaller than conventional devices of this type.
