Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a small-sized rice huller for household use, and more particularly to a mounting structure of a sorting chamber for sorting a mixture of brown rice and rice husk after hulling. .

[Conventional technology]

A small-sized rice huller for home use has a hulling part equipped with an impact type debarking device in its housing, a sorting room for sorting a mixture of brown rice and rice husks carried out from this hulling part, a rice milling part, etc. It is configured to be integrated. Then, the rice husks and brown rice dehulled in the hulling section are air-transported in the transport pipe by the dehulling fan to enter the sorting chamber,
Here, brown rice and rice husks are selected. After that, the brown rice is carried out to the tank of the rice polishing unit, while the rice husk is sucked by the suction fan and discharged to the outside of the machine through the discharge pipe.

As described above, most of the operations of transporting and discharging brown rice and rice husk depend on air transport. Therefore, each part such as the sorting chamber and the pipe needs to be airtight, and therefore, these parts are firmly connected to each other and also firmly supported to the body housing, and the joint part of each part is connected. It is structured so that there are no gaps.

[Problems to be solved by the device]

As described above, in the conventional hulled rice milling machine, it is difficult to clean the sorting chamber because the sorting chamber is built in the machine body housing. It is conceivable to remove the sorting chamber from the housing in order to facilitate cleaning work.However, because the sorting chamber is firmly fixed to the housing etc. due to the need for airtightness as described above, this removal The action is not easy, and after all, the sorting chamber is not easy to clean.

Further, since the sorting chamber is incorporated in the machine housing, the overall size of the machine is large, which makes transportation of the huller inconvenient.

In view of the above points, an object of the present invention is to realize a hulled rice polishing machine in which the sorting chamber can be easily cleaned and transported.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the present invention, a hulling part for dehulling the hull, and a wind-screening type sorting part for selecting brown rice and hulls from the sludge obtained by the hulling part, A transport pipe that blows the sludge from the hulling unit to the sorting unit, a rice polishing unit that whitens the brown rice obtained in the sorting unit, and the rice husk is sucked and discharged from the sorting unit to the suction fan side. In the rice hulling machine with a discharge pipe, the sorting unit is a unit removable from the upper surface of a main body housing that houses the hulling unit and the rice polishing unit, and the transport pipe has a lower end side of the rice hull. A main body side pipe that is connected to the sliding portion and has an upper end side opening to the upper surface; and an upper end side that is connected to the sorting chamber inlet of the sorting section and a lower end side that has packing inserted in the opening of the main body side pipe. If it is a pipe on the sorting section that is detachably connected, A lower end side of the discharge pipe is connected to the suction fan side and an upper end side of the main body side pipe is opened to the upper surface; and an upper end side is connected to a rice husk discharge port of the sorting chamber and a lower end side is the main body side pipe. It is characterized in that it is composed of a pipe on the side of the sorting section that is connected to the opening of the so as to be able to be inserted and removed.

Further, the sorting unit has a swing gutter capable of changing a falling path of the brown rice sorted in the sorting chamber to either the rice polishing unit inside the main body housing or the outside of the main body housing. .

[Action]

According to the present invention, a unitized sorting unit is detachably attached to the upper surface of the main body housing, and a transport pipe and a discharge pipe communicating with the sorting unit are divided into a main body side pipe and a sorting unit side pipe, respectively, and are transported. A packing is interposed between the main body side pipe of the pipe and the sorting section side pipe so that it can be attached and detached, and the sorting section side pipe of the discharge pipe is connected so that it can be inserted into and removed from the main body side pipe of the discharge pipe. It is characterized by With such a characteristic configuration, the main body side pipes of the transport pipe and the discharge pipe are separated from the sorting part side pipes by removing the sorting part on the upper surface of the main body housing upward. Therefore, there is an advantage that the selecting section can be easily separated from the main body housing simply by removing a mounting screw or the like for the selecting section and the main body housing, and the selecting section can be appropriately cleaned. The reason why the packing is inserted between the main body side pipe and the sorting part side pipe of the transport pipe is that the sorting part is blown by the discharge pressure of the main body side pipe when the sludge is blown from the hull part to the sorting part. Since it acts in the direction of separating the connection of the side pipes (upward), this is prevented by the pressing force due to the attachment of the selection section, and the upper airflow of the slid matter is reliably performed. To separate the sorting unit from the main body housing, the connection between the main body side pipe and the sorting unit side pipe is quickly released. On the other hand, no packing is particularly provided at the connecting portion between the main body side pipe of the discharge pipe and the sorting section side pipe, and the lower end side of the sorting section side pipe is simply inserted into the opening of the main body side pipe. This is because the internal pressure of the main body side pipe automatically sucks the sorting part side pipe itself, so that the connection part is closely fitted without a gap. Therefore, when the sorting unit is separated from the main body housing, there is no automatic suction due to the stop of the rice polishing machine, so that the connection between the main body side pipe and the sorting unit side pipe is easily released.

Further, since the unit of the selection unit is attached to the upper surface of the main body housing, the main body housing itself has a small size.
Therefore, it is convenient for transportation.

Furthermore, the present invention is characterized in that the sorting unit has a swing gutter capable of changing the falling path of the brown rice sorted in the sorting chamber to either the rice polishing unit inside the main body housing or the outside of the main body housing. . Therefore, by simply reversing the swing gutter by hand, it is possible to change the dropping path of the brown rice and drop it into the rice polishing portion of the main body housing, or drop the brown rice into a grain bag or the like outside the main body housing. Since only the swing gutter is sufficient as the switching mechanism for changing the grain path in this way, a rice mill having a small number of parts and a low cost can be realized.
