Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a rotary sorting machine in which a receiving gutter is inserted through and horizontally hung in a sorting cylinder which has a number of depressions formed in its inner peripheral surface and is rotatably hung horizontally. A plurality of grain frying buckets are attached at equal intervals to the inner circumferential surface of the grain discharge side of the body, and the grains that have passed on the circumferential surface of the sorting cylinder and reach the discharge side end are scooped out by this grain frying bucket. This invention relates to a gutter for taking out grains that receive the grains that are scooped up and do not take them out of the machine from a high place inside the sorting cylinder.

That is, the receiving plate of this lifting grain removal gutter is provided close to the lower side of the rotating locus of the above-mentioned grain-frying bucket, and the side plate extending downward from the grain receiving side of this receiving plate is provided for lifting grains. It is formed into a curved surface that maintains a small gap with the rotating trajectory of the bucket, so that the grains that are to be scooped up by the grain frying bucket are smoothly and reliably placed on the receiving plate so that they do not fall out of the grain frying bucket. The purpose is to lift the vessel.

The present invention will be explained below with reference to embodiment figures.
This embodiment shows a rotary sorting hulling device combined with a rotary sorter equipped with a lifting grain removal gutter according to the present invention, in which (a) shows the shedding part, and (b) shows the selection part, (c)
is a rotary sorting machine, and the removing section (a) is placed before and after the wind sorting section (b).
and a rotary sorting machine (c) are installed in an integrated structure.

Therefore, the explanation of the removing section (a) and the wind sorting section (b) will be omitted, and the explanation will focus on the rotary sorting machine (c).

(1) is a sorting cylinder with a number of depressions (2) formed on its inner circumferential surface, and both front and rear ends are horizontally mounted so that they can be rotated by drive wheels (3) and (4), respectively. In this case, the rotation axis of the sorting cylinder (1) is installed in the front-rear direction, and the supply side (X) of the mixed grains is placed at the rear and the discharge side (Y) is placed at the front. ) is adjacent to the detached part (a). (5) (6) is the supply side (
A mixed grain transfer gutter and a brown rice receiving gutter are horizontally suspended from The mixed grain transfer gutter (5) is from the discharge side (Y) to the supply side (X)
A drop port (9) is opened to transfer the mixed grains toward the supply side (X) and drop them from the supply side (X), and the brown rice receiving gutter (6)
X) to the discharge side (Y).

A plurality of grain frying buckets (10) are equally distributed on the inner circumferential surface of the discharge side (Y) end of the sorting cylinder (1), and the grain frying buckets (10) are An annular blocking plate (11) is joined to the outside to prevent the grains reaching the discharge side (Y) end from spilling out.

(12) is a lifting trough for taking out grains, which includes a receiving plate (1, 2a) that slopes low forward and serves as a surface for taking out grains, and this receiving plate (], 2a).
) side plates (12b) extending downward from both sides of the
(12C) into a substantially trapezoidal shape, and its receiving plate (1
2a) is located close to the lower side of the rotating trajectory of the fried grain bucket (10), and also connects the mixed grain transfer gutter (5) and the brown rice receiving gutter (6).
It is welded to the front wall (13) of the rotary sorter (C) so as to straddle the top.

That is, (12d) shown in FIG. 4 is the adhesive surface to the front wall (13).

Therefore, among the side plates (12b) (12c), the side plate (12b) located on the grain receiving side onto the receiving plate (1o)
(10) Rotation locus and slight gap (S
) is formed into a curved surface (R) according to this rotational trajectory.In addition, the receiving plate (12a) on the opposite side of the front wall (13) and this side plate (12b) part have a raised edge (14). There is.

An outflow port (13a) that communicates with the outside of the machine is provided at the bonded part of the front wall (13) to the receiving plate (12a), and this outflow port (13a) is further connected to the adjacent detachable part (a). ) is aligned with the reduction port (15a) opened in the rear wall of the paddy tank (15).

(16) is a space ( P) on the front wall (
13), and the upper end opening is this front wall (13).
It penetrates through and looks into the mixed grain transfer gutter (5).

In addition, the discharge side (Y) of the brown rice receiving trough (6) is connected to the drop path (17
).

Therefore, the mixed grains of brown rice and paddy after wind selection that are shed by the shedding section (a) and the wind sorting section (b) are lifted into the mixed grain transfer gutter (5) by the thrower (16), and are lifted up into the mixed grain transfer gutter (5) on the supply side. After being transferred toward (X), it falls from the drop opening (9) onto the inner peripheral surface of the sorting cylinder (1). The mixed grains that fell onto the inner peripheral surface of this sorting cylinder (1) are
A recess (
Due to the scooping action (2), the particles are sorted while the particles gradually flow in the direction shown by the arrow (b) in FIG.

In other words, brown rice, which is smaller in size than paddy, is difficult to escape from the depression (2) and is scooped up to the highest level, forming a parabola and falling into the brown rice receiving trough (6), and the brown rice cannot be scooped up to the highest level. The remaining paddy falls into the mixed grain transfer gutter (5) and joins with new mixed grains, and the paddy that cannot be scooped out is transferred to the discharge side (Y) by repeating the sorting action by the depression (2) again. The grain is scooped up by the frying bucket (10) and placed on the receiving plate (1).
2a), the paddy is guided forward on this receiving plate (12a), passes through the outlet (13a) and the return port (15a), and is returned to the tank (15) where it is fed.

In this case, the paddy to be scooped up by the grain frying bucket (10) is placed on the curved surface (R) of the side plate (12b).
It is lifted up and carried onto the receiving plate (12a) while being guided without falling.

Furthermore, the brown rice that has flowed into the brown rice receiving trough (6) is discharged from the discharge side (Y
), passed through a falling path (17), and is taken out after wind selection in a wind selection section (b).

As described above, the present invention provides a rotary sorting machine in which a receiving gutter is inserted through and horizontally hung in a sorting cylinder which has a number of depressions formed in its inner peripheral surface and is rotatably hung horizontally. A plurality of grain frying buckets are installed at equal intervals on the inner peripheral surface of the grain discharge side end, and a lifting grain removal gutter whose catch plate communicates with the outside of the machine is placed under the rotation trajectory of the grain frying buckets. The side plate is provided close to the side, and the side plate extending downward from the grain receiving side of the receiving plate is formed into a curved surface that maintains a slight clearance from the rotation locus of the grain frying bucket. The grains that are not scooped up and reach the discharge side end of the sorting cylinder are scooped up as they are by the grain-lifting bucket and taken out from a high place inside the sorting cylinder by the lifting grain removal gutter, so a separate lifting device is required. Not only does it simplify the structure as there is no need to provide it, but the grains to be scooped up by the grain-lifting bucket are placed along this rotation trajectory so as to maintain a slight gap from the rotation trajectory of the grain-lifting bucket. The lifting was smooth, reliable, and efficient because it was guided by the side plates with curved surfaces and lifted without falling.

If the grain-frying bucket is made of an elastic material, even if it comes into contact with the curved surface of the side plate, it can perform the lifting action comfortably without making any noise.
