Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) In this invention, a sorting tube rotates and 31 mm is placed on one inner circumferential surface. This invention relates to a rotary sorting device that sorts grains while scooping them up in a hollow.

(Prior Art) There is a structure in which an upright surface is provided at the end of the sorting tube on the sorting terminal side.

(Problems to be Solved by the Invention) However, in the structure described above, the layer thickness of the grains subjected to the sorting action may become thicker at the end of the sorting. Therefore, the desired recovered grains (for example, brown rice) that are mixed in the grains are sent to the removing device again and subjected to the removing action, causing skin slippage (scarring on the surface). and side trees are more likely to occur.

(Means for Solving the Problem) The present invention aims to solve the above technical problem, and has taken the following technical means.

That is, a large number of depressions (1) are formed on the inner circumferential surface of the rotatably installed sorting tube (2), and the upright surface (c) on the sorting end side is located closer to the center of rotation of the tube (2) than the upper end surface. The structure is such that there is a grain-receiving upright surface that protrudes toward the grain.

(Operation) The grains supplied into the sorting tube (2) are passed through the rotating sorting tube (2).
The scooping by the depression (1) in 2) moves from the sorting starting end side to the other side due to the action and the pressing action of the grains, and during this time, the specified grains (for example, brown rice) are removed from the grain group. It will be collected. Since the grains that are not collected are stopped by the grain receiving surface (goods) at the moving speed, the layer of grains located between the grain receiving surface (goods) from the sorting start point can be thickened and the grains can be grained. To improve the fitting of desired recovered grains (for example, brown rice) mixed in a grain group into the depression (1) and upward movement. Furthermore, the grain layer thickness between the grain receiving surface (a) and the upright surface (g) can be made thinner, and the amount of desired collected grains returned to the shedding device can be reduced.

(Effect) Since the grain layer thickness between the sorting start end of the sorting tube (2) and the grain receiving surface can be formed thickly, it is possible to improve the recovery efficiency of the desired collected grains mixed in the grains. . Since it is possible to reduce the amount of the desired recovered grains returned to the shedding device, it is possible to reduce the occurrence of skin slippage, side grains, etc.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Equipped with equipment α◆ for conveying and finishing rice. In the conveyance device, the conveyance end portion of the finished rice conveyance device α is communicated with the finished rice recovery device (to) via the finished rice guide cylinder. In addition, the above-mentioned supply conveyance device! t(13 is sorting WJ(2
) is configured to collect the mixed grains subjected to the sorting action and feed them again into the sorting tube (2) from the conveyance end, and also serves as a mixed grain conveying helix.

The sorting tube (2) also includes a supply side sorting tube aQ whose both ends are formed into flat plates and a number of depressions (1) formed on the inner peripheral surface between the flat plates, and a supply side sorting tube α0. The discharge-side sorting cylinder αη, which is formed shorter than The face (a) is
The sorting end side 41 f of the discharge side sorting tube α protrudes toward the rotation center of the sorting rfI (2) (ie, H>h) than the upright surface (to) provided thereon.

If the η and grain receiving plate 01) are configured to be removable using fixing devices (e.g. bolts and nuts), the properties of the grains (e.g.
The discharge side sorting tube αη having different depths and sizes of the recesses (1) can be selected and changed depending on the size of the grains, thereby improving the adaptability of the sorting work. Further, the supply side sorting tube αQ may be replaced. Furthermore, if the structure is configured as in this embodiment, grain receiving plates 0υ of different heights can be selected and attached, so that the adaptability of the sorting work can be further improved.

The wind selection room (7) is composed of a suction device (1), a mixed grain recovery device υ, and the finished rice recovery device (to).

Kan and Kan are mixed grain collection device C! They are a mixed rice thrower and a finished rice thrower that feed the mixed grains collected by the υ and finished rice recovery device (to) to the conveyance device (to), and fry the finished rice outside the machine.

(c) is karin. (To) is a paddy thrower that throws the grains to the side of the device (5) that removes the mixed grains with a low yield rate discharged from the rice cracker (2). (E) is the supply funnel.

Next, to explain its function, the grains (hulls) supplied into the supply funnel (1) are shed by the shedding rolls of the shedding device (5), and then moved into the wind sorting room (7). The grains fall to the bottom and are collected by the mixed grain collection device Q1) below, but during this time they are subjected to air pressure and suction sorting by the suction device (1) and the winnowing machine (C). Then, the air-selected mixed grains are fed to the conveyor α3 using a thrower.
After the grain is fried inside, it is conveyed by the conveying helix (9) and the receiving gutter αη, and from the conveyance end, it is discharged into the supply side sorting tube aQ, where it is successively scooped up in the recess (1) and subjected to sorting action. receive.

Then, the brown rice was collected into the finished rice conveying device α, and the mixed grains were collected at the mouth of the supply conveying device, and this brown rice (finished rice) fell from the quick end via the finishing main guide circumference to the finished rice collecting device 0th. The mixed grains are then discharged to the outside of the machine at the thrower, but on the other hand, the mixed grains are returned to the sorting tube (2) from the conveyance end along with the supplied mixed grains.

Mainly paddy) is discharged from the cut end of the sorting tube on the discharge side of the sorting tube (2), and then air-sorted and fried to the side of the device (5) where the paddy is fed in the paddy thrower.

During such sorting work, the mixed grains moving inside the supply-side sorting tube αQ are caught by the grain receiving surface □□□ provided at the end of the sorting tube, and the moving speed is regulated. , the layer thickness becomes thicker. Therefore, the brown rice in the mixed grains is removed from the discharge side sorting tube α.
Since the movement within η can be reduced, it is possible to reduce the occurrence of skin slippage and splints caused by double rubbing of brown rice. Moreover, the brown rice in the feed-side sorting cylinder αη can easily fit into the depressions (1), and can be easily moved to a predetermined height due to the layered grain pressure. Prevents falling and improves collection efficiency. Furthermore, since the upright surface of the discharge-side sorting tube αη is lower than the grain-receiving upright surface, the discharged grains do not significantly stagnate in the discharge-side sorting tube αη, and the efficiency of sorting work can be improved. Moreover, if the grain receiving upright surface is provided on the sorting end side of the sorting tube (2) as in the embodiment, the effective sorting area of the supply side sorting tube αQ can be widened and work efficiency can be improved. can be achieved.
