DETAILED DESCRIPTION OF THE INVENTION This invention has a de-sexing chamber and a sorting hall, and the grains to be sorted which have been de-sexed and the sorted grains which have been sorted are conveyed by a conveying helix installed on the same axis. This relates to a grain conveying device in a sliding machine.

A supply helix that transports the grains to be sorted to the sorting starting end side of the sorting cylinder and a mixed grain conveying helix that transports the mixed grains of brown rice and paddy that have undergone the sorting action are installed separately in the sorting cylinder.・It requires many parts such as bearings and pulleys, and the structure is complicated and expensive.

In addition, a great deal of time and effort is required when assembling or disassembling the conveying helix, and additional effort is required when cleaning the remaining grains after the work is completed. Furthermore, since four general feeding devices must be installed in a limited space within the sorting cylinder, it is difficult to perform the assembly and disassembly operations described above.

This invention has taken the following technical measures to solve the above problems.

That is, 1lQb of this sorting cylinder (1) is formed in the sorting cylinder (1) with a large number of depressions (1a) formed on the inner circumferential surface.

A mixed grain conveying helix (3) for conveying mixed grains and a supply rail for conveying grains to be sorted are provided in the same helical shaft (2) with conveying helixes having opposite winding directions fixed to the outer peripheral surface of the same helical shaft (2). -1! /(4), and the conveyance start end of the supply helix (4) is connected to the sorting grain supply chamber (5), and its conveyance path 1: A1 section is connected to the sorting start end of the sorting circle 1:1j (1). A grain conveying device in a rice hulling machine characterized by communication.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

First, to explain its configuration, the huller (6) has a deweighing chamber (7) and a sorting chamber (8) at the top, and a winnowing chamber (9) at the bottom.
The grains (mixed grains) that have been subjected to the decontamination effect in the decontamination chamber (7) are wind-selected in the wind selection chamber (9), and then brown rice (
It is configured to sort into finished rice) and paddy. and,
The western-style room (7) has a pair of left and right rows that rotate in different directions in a casing with open upper and lower ends.
7b) with an internal shaft rack and a supply funnel (10) installed at the top.
The grains supplied therein are subjected to a shedding action by the shedding rolls (7a) and (7b).

The sorting chamber (8) has a cylindrical sorting cylinder (1) formed with a large number of circular depressions (1a) on its inner circumferential surface and configured to rotate with a driving body (11). . The sorting cylinder (1) is equipped with a grain conveying device (13) of the finished rice conveying device 0 consisting of a conveying helix (12a) and a receiving gutter (12b).The grain conveying device 0 is the sorting room (8) and the helical shaft (2) rotatably attached to the machine frame.
A mixed grain conveying helix (3) and a supply helix (4) are formed by fixing helices with opposite winding directions to each other, and a receiving trough Oa is installed below both of the helices (3) and (4). It consists of

The conveying start end of the mixed grain conveying helix (3) is connected to the feeding helix (4).
), and the conveyance terminal end is communicated with a discharge path 0υ formed on the side of the sorting chamber (8) on the side of the western-style removal chamber (7).

On the other hand, a mixed grain supply funnel 0Q was installed at the conveyance start end of the supply helix (4), and the grains to be sorted were supplied to the upper part of the sorting chamber (8) (on the deweighing chamber side) via the supply cylinder α force. Room (5
), and the conveyance terminal end looks into the sorting start end of the sorting cylinder (1) on the opposite side from the removal chamber (7). Note that both the finished rice transport device Oa and the grain transport device (14) have axes in the same direction as the sorting cylinder (1).

α8) is a cover plate that covers the upper part of the supply helix (4), and is formed so that the mixed grains scooped up by the sorting cylinder (1) are not collected between the supply helices (4).

The wind selection room (9) has a suction device (19) and a mixed grain collection gutter (7).
It consists of two collection gutter 01) and is configured to collect the mixed grains and finished rice (brown rice) that have been guided into the room after being screened. (c) is a thrower for frying the mixed grains collected in the mixed grain collection gutter into the grain supply chamber (5) to be sorted. The seedlings are connected to the feed funnel 00 through a paddy collecting 4-channel sakaki installed above the sorting end Jiff of the sorting cylinder (1) and through the thrower (c). In other words, it is a thrower that takes out the finished rice collected in the finished rice collection gutter I2) out of the machine.

Next, to explain its function, the paddy supplied into the supply funnel 00 is transferred to the dehulling rolls (7a) (7) in the dehulling chamber (7).
After being subjected to the deweighing action in step 1)), it falls into the wind sorting chamber (9) and is collected by the lower l'fA aggregate collection gutter. Then, the wind-selected mixed grains are fried into the sorted grain supply chamber (5) by a thrower, and then fed to the sorted grains a1 via the supply tube Q71.
It is sent from Doo OQ to the supply helix (3) and transported,
From the end of the conveyance, it is discharged into the sorting cylinder (1) and subjected to sorting action. From the sorting start end of the sorting cylinder (1) to the conveyance start end of the supply helix (4), even if the mixed grains try to enter the supply helix (4), they are guided downward by the cover plate and rotated again. There is no rice, and only the unpolished rice (shi) that has been scooped further upwards in the depression (1a) is transferred to the finished rice conveyor (
b) and transported to the discharge path θυ side. Therefore, the grain pressure on the brown rice contained in the depressions (11) between the supply helices (4) can be high, so that this brown rice is scooped up and transferred to the finished rice conveying device (14). dimple(
It does not fall off from 1a), and the collection efficiency of brown rice can be increased. At the sorting end of the sorting cylinder (1), not only the brown rice is collected by the finished rice conveying device (12), but also the mixed grains are collected by the mixed grain conveying helix (3) and the receiving gutter 04. It is possible to prevent the brown rice mixed in the limb sorting position from being supplied to the weighing chamber (7) side and being subjected to the sliding action twice. Therefore, it is possible to prevent damage to the outer skin of brown rice and cracking of the shell due to double rolling, and to obtain high quality finished rice.

Then, the mixed grains falling from the discharge channel 0 are subjected to wind separation on the way, and the mixed grains are collected into the mixed grain collecting gutter and the finished rice is collected into the finished rice collecting gutter Qυ, where they are respectively sorted. The grains are fried in the grain supply chamber (5) or in the thrower (2) 9 outside the machine, while the unrecovered grains discharged from the sorting end of the sorting cylinder (1) are sent to the paddy recovery device (c). After being collected by the thrower (c), it is fed into the supply ear α0) and subjected to the deweighing action again.

As explained above, this invention provides a rotatable helical shaft having an axis in the same direction as the axis of the sorting cylinder in a sorting cylinder having a large number of depressions formed on the inner circumferential surface. A mixed grain conveying helix that conveys mixed grains and a supply helix that conveys grains to be sorted are formed by fixing conveyor helices having opposite winding directions to the outer circumferential surface of the helical shaft. Since the conveyance terminal end of the sorting grain supply chamber is communicated with the sorting start end of the sorting cylinder, there is no need to provide a supply helix and a mixed grain conveyance helix separately and independently in the sorting cylinder. The structure is simple and can be manufactured at low cost. Second, even after the work is finished, the amount of particles remaining in the conveying helix can be reduced, making cleaning easier and preventing the mixing of different types of particles. In addition, since the number of conveying spirals can be reduced, assembly and disassembly of the sorting device can be simplified to 1n1, the number of balls to be inspected and maintained can be greatly reduced, and a significant improvement in production efficiency can be expected.
