Description

[Detailed Description of the Invention] This invention provides the ability to use grains and other granules such as rice and wheat.
While rising inside the cylindrical sorting mesh installed inside the shell,
This invention relates to a vertical grain sorter that separates large-diameter regular grains and small-diameter waste grains.

In a spar-type granule sorter, the upper surface of the spiral blade of the spiral tube that has been collected into one cylindrical sorting net is made to have a dynamic frictional resistance greater than that of a flat metal plate, and the granules lifted by the spiral blade are agitated. The applicant has already filed a patent application for an invention that improves the sorting rate while applying centrifugal force!
;7-37 Proposed as an issue. In this agricultural invention, the layer of granules lifted on the upper surface of the spiral blade is thin, that is, the processing f.
It is particularly effective when the amount of M is small, but if the layer of each grain is thick, that is, the throughput is large (there is a tendency that the grains in the upper layer are not sufficiently stirred and the sorting rate decreases; This was discovered through experiments.

This invention solves the above-mentioned disadvantages.

It was constructed as follows. Namely, a cylindrical sorting net (1) and a spiral tube for lifting grains (2) fitted in this sorting net (1).
) is installed vertically so as to rotate concentrically with τ.In a vertical particle sorter t, a spiral tube ( 21
The outer circumferential surface (4) of the container was configured to have a particle stirring function.

The present invention achieves the following technical effects with the above configuration. In other words, as the number of grains lifted on the upper surface of the spiral blade of the spiral tube (2) increases, the thickness of one grain becomes thicker, but the outer peripheral surface (41 Since the stirrer a installed in the granules acts and stirs the entire granules, the 1 sorting rate becomes good, and the decrease in the sorting rate can be minimized even though the throughput is increased.

Next, the configuration of an embodiment of the present invention will be explained with reference to one drawing.

The overall groove structure of the Zhuang C-type granule sorter is as shown in Fig. 1, with a large number of sorting holes (3

On the lower side of the discharge window 08 of this sorting net (1), there is a ten-round eave (one sorting hole, one sorting hole, one

The lower 9 gutter (11) connects an annular groove similar to the receiving gutter QS to the outside of the shell (5) off the waste grain outlet f, and passes through the 1 sorting net (11 sorting hole 13) to prevent leakage. After receiving P#, the waste particles can be taken out from the shell body (5) through a separate outlet C using a scraper.

In the area corresponding to the drilling range of the spiral I'+21t, the 5 sorting nets (the cylindrical body tZU is fixed to the spiral bean paste in A of 11, and the separation hole 13 of the 1 sorting net (1)) are drilled.

Note that in the embodiments shown in Figures 2 and 3, the piles do not have a structure that provides IM friction resistance on the upper surface of the spiral tube, but as in these embodiments, the screening mesh (1) If the inner diameter of the spiral blade is close to the outer diameter of the cylindrical body and the span of the 62-blade spiral blade is narrow, this configuration is not necessary because it is strongly affected by the stirring action of the outer periphery of the 62-blade spiral blade.

Next, the sorting action of one grain is explained as follows.

Small-diameter waste grains are sieved out to the sieve area 0 in the shell (5).

Large-diameter regular particles are discharged from the discharge window (18) to the sloping area α6) in the shell (5). Furthermore, the waste grains are taken out of the small shell (5) one by one, and the sized grains are stored in the tank (7). Grain regulation in the tank (7) is done using shutter 00.
