To provide a device for lifting granular materials, etc., which can feed pachinko balls that have been lifted up to a distribution gutter on an island with priority over pachinko balls that are supplied to a distribution main tank.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIGS. 1 to 6 schematically show an embodiment in which a device for transporting granular materials, etc. according to the present invention is applied to a pachinko machine island in a pachinko game hall. Pachinko ball 2 and ball polishing material 3
The storage unit 5 includes a storage unit 5 for accommodating granular materials 4 and the like, a transfer means 6 and a lifting unit 7 disposed within the storage unit 5.

The storage section 5 is formed in a cylindrical shape, and an inlet 8 for granules and the like is formed in the upper part of the storage section 5. A lifting pipe 9 of a lifting means 7 is arranged in an upright state above the storage section 5. The lower end of the lifting pipe 9 is opened to form an intake port 10 for the particulate matter 4 and the like, and this intake port 10 is inserted into the storage section 5 .
Further, a drive motor 14 is attached to the upper outer periphery of the lifting pipe 9, and an output shaft 14a of this drive motor 14 is attached.
A pulley 15 is fixed to and connected via a rotation transmission member 17 to a lift pulley 16 rotatably disposed inside the lift pipe 9 . The upper part of a spiral wire ring 18 is fixed to the shaft part 16a of the lift pulley 16, and the upper part of the spiral wire ring 18 projects downward from the intake port 10 at the lower end of the lift pipe 9.

At the top of the lifting pipe 9, there is a discharge port 1 for discharging particulate matter 4, etc.
9 is formed, and a screen-like separation gutter 20 that slopes downward is disposed at this discharge port 19, and this separation gutter 2
A distribution gutter 21 is connected to the downstream side of 0, and a separation gutter 20
The ball polishing material 3 separated by is dropped and pachinko balls 2
Only the water can be supplied to the distribution gutter 21.

A gathering part 22 is formed below the separation gutter 20,
The ball polishing material 3 collected from this gathering part 22 is dropped to the lower part through a pipe 23. In this embodiment, the lower end of the pipe 23 is extended to the reservoir 5, and the separated ball polishing material 3 is supplied to the reservoir 5. Further, an input port 24 is formed in the lower part of the pipe 23 so that the ball polishing material 3 can be input into the storage section 5 separately from the inlet 8 of the storage section 5.

A spiral wire rod 2 as a transfer means 6 is placed in the storage section 5.
5 are arranged. This spiral wire 25 is formed into a flat shape, and a connecting member 26 is fixed to the winding start end at the center, and this connecting member 26 protrudes downward from the lower end of the lifting pipe 9 of the lifting means 7. It is connected to the spiral wire ring 18, and is configured so that when the spiral wire ring 18 is rotated by the rotational driving force of the drive motor 14, the spiral wire rod 25 of the transfer means 6 also rotates at the same time. The winding direction of the spiral wire 18 is determined so that the granules 4 and the like rise along the pitch of the spiral wire 18 by rotation of the spiral wire 18 in the direction of the arrow X, while the spiral wire 25 is Figures 3 and 4
As shown in the figure, the spiral wire 25 is wound outward from the central winding start end in the same direction as the rotation direction, and the rotation of the spiral wire 25 in the direction of the arrow X causes the particles 4, etc. to become swirled. In the direction of arrow l toward the center of
That is, the granules 4 and the like existing between the wire rods 25 are sequentially moved toward the intake port 10 of the lift pipe 9 by the rotation of the spiral.

Further, in the central portion of the spiral wire 25, the moved granules 4 and the like move upward.

That is, the pachinko ball 2, the ball polishing material 3, etc. are moved from the periphery toward the center as shown by arrow l, and then moved upward near the center as shown by arrow m.

The pachinko balls 2 and the like that have been moved upward near the center are taken into the spiral ring 18 and rise while being stirred in the lifting pipe 9.

The pachinko balls 2 and the like that have not been taken into the spiral wire ring 18 are moved to the outside of the circumference as shown by the arrow n, and are again moved in the direction of the arrow l.

Therefore, part of the particulate matter 4 etc. circulates as shown by the arrows 1→m→n, and as shown in FIG. 3, a virtual line of force q exists.
