Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a leveling body for a swinging type grain sorting device.

(Prior Art) Conventionally, it has been known to provide a comb-like scraper on the top of a grain sorting plate that swings horizontally or obliquely to scrape down remaining straw waste.

Furthermore, Japanese Utility Model Application Publication No. 54-38969 discloses a device in which a plurality of fixed comb-like scrapers are provided at predetermined intervals in the tablet flow direction on a grain selection plate that is low in the tablet flow direction. It is described that a gap is formed between the lower end of the body and the upper surface of the grain selection plate.

(Problems to be solved by the invention) The former has a complicated structure because it is provided to sweep the grain selection plate from the high side to the low side.

In the latter case, since neither the grain sorting plate nor the comb-shaped scraping body shakes, when used for materials containing straw waste such as grains,
It gets stuck and cannot be sorted smoothly.

(Purpose of the invention) Therefore, the present invention provides a device that can smoothly sort even grains that contain straw waste.

(Means for Solving the Problem) Therefore, in the present invention, a plurality of fixed comb-like leveling bodies 29 are provided at predetermined intervals in the grain flow direction on the immature rice grain sorting plate 23 that is low in the grain flow direction. A gap 24 is formed between the lower end of the scraper 29 and the upper surface of the unripe rice grain sorting plate 23, and the fixed comb-shaped scraper 29 can be oscillated horizontally or tilted together with the grain sorting plate 23. This is a leveling body for a swinging type grain sorting device.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a tensioning elevator. A supply tank 2 is attached to the upper end of the elevator, and an on-off valve 3 is provided at the lower end of the supply tank 2. A rice hulling part 4 is provided at the lower end of the valve 3. 5
1 is a wind sorting room, 6 is an exhaust pipe for blowing away the wind-selected rice grains, 7 is a motor for rotating the hulling roll and the windmill, 8 is each pulley, and 9 is a belt.

The hulling section 4 and the winnowing chamber 5 are placed on the upper part of a stand 10, and the lower part of the stand 10 is provided with a multi-stage swing type grain sorting device 11. 12 is a sink plate that guides the rice grains that have fallen from the wind selection room 5 to the right side; 13 is a sink plate that takes over from the sink plate 12 and guides it to the left side; 1
Reference numeral 4 denotes a dividing portion that divides the flow onto the sorting plates 15 of each stage.

A finished rice outlet 16 is provided on one side of the sorting plate 15.
, and a paddy rice outlet 17 is formed on the other side.
An immature grain sorting section 18 is formed below the finished rice outlet 16. The immature grain sorting section 18 is formed to be high on the side of the dividing section 14 and low on the opposite side of the dividing section 14, and the end 1
9 faces the loading port 21 of the finished rice frying barrel 20. The structure of the immature grain sorting section 18 is that an immature rice grain sorting plate 23 with sorting holes 22 formed on the upper surface is attached, and a gap 2 is formed on the lower side.
4, a net 25 is attached, and a ball 26 for removing clogged grains is provided between the immature rice grain selection board 23 and the net 25. 27 is the bottom plate of the immature grain sorting section 18;
A large number of protrusions 28 are provided on the top.

Thus, a comb-shaped scraper 29 is fixedly attached on the immature rice grain selection plate 23. The direction of the leveling bodies 29 is a direction perpendicular to the grain flow direction, and a desired number of leveling bodies 29 are installed at regular intervals in the grain flow direction.

30 is a comb tooth, but its lower end does not reach the surface of the immature rice grain selection plate 23 as shown in FIG.

31 is an immature grain outlet, 32 is a rocking device, and 33 is a tensioning hopper.

(effect) Next, we will discuss the effect.

When unhulled rice is supplied to the tensioning hopper 33, the tensioning elevator 1 is raised and the rice is stored in the supply tank 2.
When the on-off valve 3 is opened, the paddy is removed in the hulling section 4,
Wind sorting is carried out in the wind sorting room 5, and the paddy grains are blown away from the wind exhaust pipe 6, and the hulled grains flow through the flow plates 12 and 13 into the flow divider 14, and from the flow divider 14, they are sent to the sorting plates at each stage. 15.

Since the sorting plate 15 is oscillated horizontally or tilted by the oscillating device 32, the sorted and finished rice is sent to the finished rice outlet 16.
The unhulled rice is taken out to the unhulled rice outlet 17.

Thus, the unhulled rice taken out to the finished rice outlet 16 is supplied to the unripe rice grain sorting plate 23 of the immature grain sorting section 18, but the immature grain sorting section 18 is integrated with the grain sorting plate 15 and is shaken horizontally or tilted. Since the rice is moving, it flows on the immature rice grain sorting plate 23 towards the diversion section 14 side or the opposite side of the diversion section 14. At this time, since a raking element 29 is provided on the immature rice grain sorting plate 23, which is perpendicular to the flow direction, the grains do not stay in one place and flow through the comb teeth 30 of the raking element 29. It is divided into left and right sides in the direction and flows to the opposite side of the flow dividing section 14.

At this time, in the present invention, there is a gap 24 between the lower end of the scraping body 29 and the upper surface of the immature rice grain selection plate 23.
At the same time, the fixed comb-like leveling body 29 is arranged to swing horizontally or tilted together with the grain sorting plate 23, so that even if there is straw waste, it is collected by the gap 24 and the horizontal or tilted swinging. sorting smoothly while preventing

In other words, in the known one, the grain sorting plate is fixed, so when there is straw debris like shells, it gets caught.
In this invention, a shaking uniform grain 29 is placed on a shaking unripe rice grain sorting plate 23.
Since the grains are provided with gaps 24 formed therein, the grains are distributed to the left and right sides by the comb teeth 30, gradually moving to the lower side, and flowing evenly over the entire surface.

When the grains flow on the immature rice grain sorting plate 23, they are sorted through the sorting holes 22, and the immature grains fall through the sorting holes 22, and then pass through the mesh 25 and onto the bottom plate 27. and is guided to the immature grain outlet 31 by the protrusion 28. The finished rice flowing out from the lower part 19 of the immature grain sorting section 18 flows into the finished rice frying cylinder 20 through the loading port 21 and is appropriately packed into bags.

(Effects) Among the known examples, the former has a complicated structure because it is provided so as to sweep from the high side to the low side on the grain selection plate. In the latter case, both the grain selection plate and the comb-shaped scraper,
Since it does not oscillate, if it is used for items containing straw such as grain, it will get caught and cannot be sorted smoothly.

However, in the present invention, a plurality of fixed comb-like raking bodies 29 are provided at predetermined intervals in the grain flow direction on the immature rice grading plate 23 which is low in the grain flow direction, and the lower end of the comb-like raking bodies 29 is A oscillating grain sorting device in which a gap 24 is formed between the upper surface of the unripe rice grain sorting plate 23 and the fixed comb-like raking body 29 is oscillated horizontally or obliquely together with the grain sorting plate 23. Since the gap 24 is
In combination with horizontal or tilted rocking, even shells containing straw waste can be sorted out well.
