Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oscillating rice sorter equipped with a plurality of oscillating sorting plates.

A rice sorting machine is known that is equipped with a plurality of vertically stacked oscillating sorting plates. This type of rice sorting machine has a supply port at the top, and the mixed rice fed into the supply port is distributed and supplied to each stacked oscillating sorting board, and sorting is performed in parallel. However, in order to maintain good sorting conditions, a certain amount of rice is required on the board, so if the amount of mixed rice to be sorted is small, use the lower sorting board. Initially, only the topmost swinging sorting board was used for sorting. However, especially in rice sorting machines equipped with a rotating oscillating sorting board, because the angle of inclination of the oscillating sorting board in the downstream direction is small, the paddy that is sorted and discharged only on the top stage enters onto the sorting board on the lower stage. Paddy was often discharged from the finished rice outlet, causing paddy to be mixed into the finished rice.

This invention was made in view of the above circumstances, and when the amount of mixed rice to be sorted is small, in order to avoid scooping of paddy by other sorting machines, only the lowest swinging sorting machine is used for sorting. The present invention provides a rice sorting machine that performs the following operations.

That is, the paddy sorting machine according to the present invention is provided by the above-mentioned supply L]
A separate direct supply path is provided that communicates only with the swinging sorting board at the lowest stage, and when the direct feeding path is closed, the mixed rice fed into the supply port passes through the distribution supply path and is distributed to each swinging sorting board. The feeder is configured to be able to freely open and close the direct feed path so that when the direct feed path is opened, the mixed rice fed into the feed port is supplied only to the swinging sorting board at the lowest stage through the direct feed path. It is characterized by having a lid. Embodiments of the present invention shown in the drawings will be described below.

1 and 2 schematically show an example of a rice sorter according to the present invention, with FIG. 1 being a front view and FIG. 2 being a plan view.

This rice sorter 1 includes a supply port 41, a sorting section 5, and a socket section 6. The sorting unit 5 includes six swinging sorting plates 7, 7. ... are provided, and these oscillating sorting boards 7, 7. ... is swung by a power motor (not shown). At the lower part of the sorting section 5, there are three drop ports facing the receiving port 6, namely, a paddy drop port 8, a mixed rice drop port 9, and a finished rice drop port 10. The paddy, mixed rice, and finished rice are dropped into the paddy receptacle 11. Mixed rice receiver 1
2 and the finished rice receptacle 13 respectively. Illustration hanging,
14.14' is a partition plate.

The mixed rice receptacle 12 and the finished rice receptacle 13 are separated by a partition plate 15, and this partition plate 15 has both receptacles 12.
A port 16 communicating with 13 is bored. Further, the finished rice receptacle 13 is provided with a bottom plate 17, and this bottom plate 17 is provided with an opening 18. In the above-mentioned outlet 16 arrangement part,
A lid 19 is provided which is rotatable in the direction of arrow A in the figure, and the passage 16 or opening 18 can be selectively closed by lid driving means. At the lower end of the socket part 6, there is a paddy discharge port 21° mixed rice discharge port 21, which communicates with the paddy socket 11, mixed rice socket 12, and finished rice socket 13, respectively.
．． 22 and a finished rice discharge port 23 are provided.
;This paddy sorting machine 1
The rice huller 2 is installed below.

A dehulling roll 24, 24' is provided to dehull the paddy newly supplied from the paddy supply port 25 and the paddy discharged from the paddy discharge port 21. A door 26 is provided above the dehulling rolls 24° 24', so that the supply of paddy to the dehulling rolls can be stopped. Depu roll 24
, 24' is provided with a ventilation chamber 27 for discharging the hulled rice husks to the outside through a rice husk duct 28. The mixed rice after shedding is transferred to the screw conveyor 29.29
' is carried to the reception port 31 of the grain lifting machine 30, and the grain lifting machine 3
0 into the mixed rice tank 32.

The mixed rice discharge port 22 is connected to the receiving port 31 of the grain frying machine 30 through a reflux path 33.
A circulation path for mixed rice is formed by the grain lifting machine 30 and the grain frying machine 30.

The finished rice discharge port 23 of the paddy sorter 1 is connected to a rotating screen 34.
It is connected to a grain sorter 3 equipped with a

The finished rice separated from the paddy by the paddy sorter 1 is removed from grain grains such as small rice by the grain sorter 3, and taken out from the outlet 35.

Next, as shown in FIGS. 3 and 4, the supply port 4 of this rice sorter 1 is provided with an input section 40, a distribution supply path 41, and a direct supply path 42. At the lower end of the distribution supply path 41, there are six shoes (a, b) each communicating with six swinging sorting plates 7, 7, . . . .

..., f) are provided. Of these 6 chutes, 2 lead to the uppermost oscillating sorting board and are as follows: c, d
, e, and f lead to the second and subsequent oscillating sorting boards in this order.

Of these, the chute f leads to the swinging sorting board at the lowest stage.

A pair of eave-shaped protruding plates 43 and 44 are provided at the upper part of the input section 40.
are provided, and below these protruding plates 43, 44, gaps 46, 47 are formed between them and the bottom plate 45 of the input section.

A valve plate 48 is provided to selectively cover either of the cavities 46, 47. The valve plate 48 is fixed to a horizontal rotating shaft 49 provided directly above the bottom plate 45, and can be freely rotated in the direction of arrow B by operating a /% handle 50 provided integrally with the horizontal rotating shaft 49. It can be rotated.

The direct supply path 42 has a lower end that communicates only with the shoe) f that leads to the lowermost swing sorting board, and an upper end that communicates with the gap 4.
It communicates with an inlet 51 provided in the lower part of the bottom plate 45 of 6.

When using this rice sorter 1 configured as described above, if the amount of mixed rice that is the raw material for sorting is large, the valve plate 48
is rotated to the left in FIG. 4 to close the gap 46 leading to the inlet 51. In this state, the mixed rice fed into the supply port 4 from the mixed rice tank 32 flows from the gap 47 through the distribution supply path 41 into six chutes (a, b, . . .
. , f), and each oscillating sorting board 7, 7 . ...
Sorting is done in parallel. On the other hand, when the amount of mixed rice decreases before the end of the work, the valve plate 48 is reversed to the right in FIG. 4 to close the gap 47 communicating with the distribution supply path 41. In this state, the mixed rice to be thrown in is introduced from the gap 46 into the inlet 51, passes through the direct supply path 42 and the chute f, and is supplied only to the lowermost swing sorting board.

In the rice sorting machine according to the present invention, when the amount of mixed rice to be sorted is small, the upper swinging sorter is not used, and the lowermost swinging sorter is exclusively used for sorting. This allows a small amount of rice to be sorted in good condition, and prevents the paddy overflowing from the oscillating sorting machine from being scooped into another oscillating sorting machine and mixed into the finished rice (brown rice). It has become possible to effectively prevent accidents.
