Disclosure of Invention
The problems to be solved by the invention are as follows:
however, in bucket wheel 100 as shown in fig. 5, in order to avoid interference between bucket 120 after the reverse rotation and bucket 120 before the reverse rotation when the buckets are reversed, a large space is required between adjacent buckets 120. Therefore, the outer diameter of the bucket wheel body 110 may be relatively large.
Therefore, an object of the present invention is to reduce the outer diameter of the bucket wheel main body in the bucket-reversible bucket wheel.
Means for solving the problems:
in order to solve the above problem, the bucket wheel of the present invention includes: a bucket wheel body; and a plurality of buckets attached to the bucket wheel main body so as to be rotatable around reference shafts extending in a radial direction of the bucket wheel main body.
According to the above configuration, the buckets can be inverted by rotating each bucket 180 degrees around the reference axis. Therefore, even if the space between the adjacent buckets is small, the bucket after the reverse rotation can be prevented from interfering with the bucket before the reverse rotation. Thus, the outer diameter of the bucket wheel body can be reduced by the amount by which the adjacent buckets approach each other.
The plurality of buckets may each include a blade, a back plate, and a pair of side plates; the plurality of buckets are respectively provided with flanges extending from the back plate and the pair of side plates to the periphery; the bucket wheel body is provided with an annular guide for supporting the flange so as to be slidable in the circumferential direction. According to this configuration, each bucket can be easily rotated along the annular guide.
A pair of stoppers may be provided on the annular guide so as to be spaced 180 degrees apart from each other; the back plate is provided with a projection that abuts one of the pair of stoppers when the bucket is rotated. According to this configuration, each bucket can be set in the correct orientation only by rotating the bucket until the projection comes into contact with the stopper.
The invention has the following effects:
according to the present invention, the outer diameter of the bucket wheel body can be reduced.

Detailed Description
Fig. 1 shows a bucket wheel 1 according to an embodiment of the present invention. The bucket wheel 1 can be used for a reclaimer installed in a stock yard, a ship Unloader (Unloader) installed in a harbor, and the like.
Specifically, the bucket wheel 1 includes a bucket wheel main body 2 and a plurality of buckets 3 arranged around the bucket wheel main body 2 at equal angular intervals. In the present embodiment, the wheel body 2 has a substantially polygonal shape having the same number of corners as the bucket 3 when viewed from the side. However, the bucket wheel body 2 may have a circular shape, for example, when viewed from the side.
More specifically, the bucket wheel body 2 includes a plurality of cross members 21 arranged on the same circumference so as to be positioned between adjacent buckets 3, and a plurality of connecting members 22 interposed between the adjacent cross members 21. As shown in fig. 2 and 3, each cross member 21 extends in the axial direction of the bucket wheel main body 2, and the end portions of adjacent cross members 21 are connected to each other by a pair of connecting members 22.
A plug plate 23 is disposed in an opening formed by the adjacent cross member 21 and the pair of connecting members 22. The plug plate 23 is shorter in length than the distance between adjacent cross members 21 and is located at the center between the adjacent cross members 21. The plug plate 23 is engaged with the pair of connecting members 22 in such a manner as to be flush with one surface (outer side surface) of the connecting members 22.
Each bucket 3 is attached to the wheel main body 2 so as to be rotatable about a reference shaft 30 extending in the radial direction of the wheel main body 2. The reference shaft 30 is located at a substantially center of the bucket 3 (for example, at a substantially same distance from a back plate 33 and a pair of side plates 34, which will be described later), and the plug plate 23 is orthogonal to the reference shaft 30.
Each bucket 3 rotates by 180 degrees between a state of opening to one side and a state of opening to the other side in the circumferential direction of the bucket wheel main body 2. In the present embodiment, each bucket 3 is manually rotated. However, the bucket 3 may be rotated by an actuator such as an electric motor.
More specifically, each bucket 3 includes a blade plate 31 having an opening for taking a load and a pair of side plates 34. Each bucket 3 includes a back plate 33 located on the opposite side of the opening, and an intermediate plate 32 located between back plate 33 and blade 31.
In the present embodiment, the pair of side plates 34 are flat plates parallel to the reference shaft 30 and to each other. On the other hand, shovel plate 31, intermediate plate 32, and back plate 33 each have a shape in which the central portion is orthogonal to side plate 34 and both end portions are spread toward side plate 34. The center and both ends of the back plate 33 are parallel to the reference shaft 30. However, it is apparent that the shape of the bucket 3 is not limited thereto. The tip end (end opposite to intermediate plate 32) of shovel plate 31 may be provided with or without a claw portion.
Each bucket 3 is provided with a flange 4 extending from the back plate 33 and the pair of side plates 34 to the periphery. In the present embodiment, the flange 4 is a substantially C-shaped plate having an arc-shaped outer end surface and a U-shaped inner end surface. The flange 4 also extends inward of the back plate 33 and the pair of side plates 34.
On the other hand, the bucket wheel body 2 is provided with an annular guide 5 that supports the flange 4 so as to be slidable in the circumferential direction. As shown in fig. 4, the annular guide 5 has a groove 51 that opens radially inward, and the flange 4 is fitted into the groove 51.
As shown in fig. 3, each side plate 34 extends outward of the annular guide 5 beyond the inner peripheral edge of the annular guide 5 in a plan view, and a notch 35 for preventing interference with the annular guide 5 is formed in a lower portion (end portion on the side of the bucket wheel body 2) of a portion beyond the inner peripheral edge of the annular guide 5.
Further, the annular guide 5 is provided with a pair of stoppers 6 spaced 180 degrees apart from each other. On the other hand, the back plate 33 of each bucket 3 is provided with a projection 36 which comes into contact with one of the pair of stoppers 6 when the bucket 3 is rotated. The stopper 6 and the projection 36 are provided with through holes 61 and 37, respectively (see fig. 4). Then, by inserting fastening members such as bolts or pins into these through holes 61, 37, each bucket 3 is fixed in a state of being opened to one or the other in the circumferential direction of the bucket wheel main body 2.
As described above, in the bucket wheel 1 of the present embodiment, the buckets 3 can be reversed by rotating the buckets 3 by 180 degrees about the reference shaft 30. Therefore, even if the space between the adjacent buckets 3 is small, the bucket 3 after the reverse rotation can be prevented from interfering with the bucket 3 before the reverse rotation. Thus, the outer diameter of the wheel body 2 can be reduced by the amount by which the adjacent buckets 3 approach each other. As a result, the weight of the bucket wheel 1 is reduced, and the height of the object to be conveyed by the bucket wheel 1 is reduced, so that the power required to rotate the bucket wheel 1 can be reduced.
In the present embodiment, the flange 4 provided to each bucket 3 is slidably supported by the annular guide 5 provided to the wheel main body 2, and therefore each bucket 3 can be easily rotated along the annular guide 5.
In the present embodiment, since the pair of stoppers 6 are provided on the annular guide 5 and the projection 36 is provided on the back plate 33 of each bucket 3, the bucket 3 can be set in the correct orientation only by rotating each bucket 3 until the projection 36 comes into contact with the stopper 6.
(modification example)
The present invention is not limited to the above-described embodiments, and various modifications are possible within a range not departing from the gist of the present invention.
For example, various structures may be adopted as the structure capable of rotatably supporting each bucket 3. For example, an outer cylinder may be provided in the wheel body 2 and an inner cylinder fitted into the outer cylinder may be provided in each bucket 3, which are not shown in the drawings.
