The lifting polishing device with an abrasive particle cleaning device according to the embodiment of the present invention has the above-described configuration, and the pachinko balls a are collected from the collection gutter 7 into the horizontal conveying tube 2 connected to the lower side of the lifting tube 1. Abrasive grains b are flowed in from the abrasive grain storage tank 8, and a mixture of pachinko balls a and abrasive grains b is pushed toward the lower side of the lifting tube 1 by the spiral body 6.
The mixture of pachinko balls a and abrasive grains b pushed to the lower side of the lifting cylinder 1 is agitated and pumped by the spiral body 5, while the dirt on the pachinko balls a is adsorbed to the abrasive grains b and polished.

When the balls are lifted up to the upper discharge port 9 formed above the lifting tube 1, they flow out to the sorting device 10 installed at the upper discharge port 9, where they are separated into pachinko balls a and abrasive particles b. The water flows down to the supply gutter 14 and is used as a supply gutter to the pachinko machine.

On the other hand, the abrasive grains b are stored in the abrasive grain tray 1 of the sorting device 10.
2, the abrasive grains are collected by the circulation pipe 15 connected to the abrasive grain tray 12, are returned to the cross-feeding cylinder 2, mixed with the pachinko balls a again, and stirred and pumped to form the pachinko balls a.
Since the surface of the abrasive particles b gradually becomes dirty over time due to repeated use, the cleaning ability decreases.

Therefore, the flow direction of the abrasive particles b, which are being returned to the dirty abrasive particles b through the circulation pipe 15, is changed to the clean circulation pipe 17 by the current changing mechanism 18, so that the abrasive particles b can be cleaned as necessary. It is.

The abrasive grains b introduced into the
The abrasive grains b pushed to the side are stirred by the rotating stirring section 26.

As the abrasive particles b are stirred, they are rubbed against each other, and dirt adhering to the surface of the abrasive particles b is rubbed off by the mutual friction, thereby being cleaned.

The dirt that has been rubbed off becomes fine dust c, which falls into the outer covering part 30 through a through hole (not shown) that is finer than the abrasive particles b opened in the clean outer part 27, and the dust is collected in the outer covering part 30. c is suctioned and collected by a suction hose 31 connected to the suction dust collector 22.

Further, the abrasive grains b stirred by the stirring section 26
is pressed by the succeeding abrasive grains b that are successively pushed by the screw part 25 which is connected to the stirring part 26 and rotates at the same time, so the friction pressure between them is increased and the cleaning effect is enhanced. It promotes it.

Although the present invention has been described above based on the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the configuration described in the claims is not changed. can.

For example, in the embodiment shown in the drawings, the clean circulation pipe 17 is branched from the outlet of the sorting device 10 to the circulation pipe 15, but it may be branched from the middle of the circulation pipe 15. The present invention is not limited to the example, and any mechanism may be used as long as it can convert the abrasive grains b flowing down into the circulation pipe 15 into the clean circulation pipe 17 as required.

In summary, the present invention provides a pumping and polishing device that mixes pachinko balls with abrasive grains and agitates and polishes them while transporting the ball, which is equipped with an abrasive grain cleaning device for cleaning dirty abrasive grains, and is equipped with a circulation pipe and a polishing device. A cleaning circulation pipe was also installed, and the flow direction of both circulation pipes could be changed as necessary to allow the abrasive particles to be introduced into the abrasive particle cleaning device for cleaning. Even when the machine is in operation, it can be cleaned as needed to deal with dirt from abrasive grains. In addition, the flow direction of both adjacent circulation pipes can be easily changed using a current changing mechanism, so when the abrasive grains are clean, they are directly refluxed through the circulation pipe, and when they are dirty, they are Since the abrasive grains are transferred to the cleaning circulation pipe side and introduced into the abrasive grain cleaning device for cleaning, there is no need to periodically take out the abrasive grains and wash or replace them, unlike in conventional pumping polishing equipment. Moreover, since the abrasive grains are cleaned only when necessary, energy is saved and the abrasive grains are not wasted by unnecessary cleaning.

In addition, the abrasive grain cleaning device cleans the abrasive grains by pushing the abrasive grains flowing in from the supply port inside the cleaning outer shell one after another to the stirring part side by the screw part rotating inside the cleaning outer shell, and Since the abrasive grains are stirred and rubbed against each other for cleaning, for example,
In a rice polishing machine, brown rice is stirred and polished without damaging the rice grains due to friction between the rice grains.In the same way, the rice grains are not cut or polished by directly contacting the abrasive material with the abrasive grains. Since dirt adhering to the surface is rubbed off and cleaned by mutual friction, the abrasive grains are not damaged or damaged and durability is not impaired.

Further, the abrasive grain cleaning device of the present invention has a main structure including a cleaning outer shell disposed horizontally, and a shaft inserted into the cleaning outer shell and rotated in the horizontal direction by a drive motor. It is composed of a clean rotary member consisting of a screw part formed in the form of a screw part and a stirring part integrally connected to the screw part, and the screw part having a shaft part and the stirring part are integrally connected to each other by the shaft part. Therefore, it is possible to reliably rotate the cleaning rotating member while applying the rotational force of the drive source as a pressing force against the drag force of the abrasive grains accompanying the rotation of the cleaning rotating member, and the cleaning effect can be exerted.

In addition, by adopting the above-mentioned simple structure, it is robust and reduces the occurrence of failures.
Furthermore, since it is possible to downsize, no special space is required even in a narrow pachinko island with little space, and if a lifting polishing device can be installed, it can be easily installed.

Furthermore, since the supply port for the abrasive grains is provided in the clean outer shell installed horizontally, it is easy to allow the abrasive grains flowing back from the clean circulation pipe to flow into the clean outer shell. Therefore, the flow does not flow unlimitedly, but rather an appropriate amount is introduced according to the conveying capacity of the rotating screw part and pushed to the stirring part, so that the amount suitable for the cleaning capacity is constantly introduced and uniform cleaning is always achieved. can be converted into

In addition, the dust generated inside the abrasive grains as the abrasive grains are cleaned is collected through the suction hose by the suction flow of the suction dust collector and stored all at once in a separate dust storage section. The suction flow does not accumulate in the covering part, and the suction flow acts as an air flow inside the clean outer shell part through the through holes, so the dust generated in the abrasive grains stirred by the stirring part is also absorbed by the air flow. Since it is successively suctioned and removed, it also has the effect of efficiently promoting cleaning by rubbing.

In this way, the reliable cleaning of abrasive grains and the treatment of dust generated as a result of cleaning of abrasive grains are equipped with a structure that does not require human labor and has a stable structure that does not cause breakdowns. This makes it possible to clean the abrasive grains when necessary in response to contamination, and to fully utilize the performance of the lift polishing device.
