Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for sorting mixed grains of brown rice and paddy obtained by desiliconizing wind sorting by forming a large number of depressions on the inner peripheral surface. This invention relates to a rotary sorting rice hulling machine which is combined with a rotary sorting section in which a receiving gutter is inserted and horizontally hung in a sorting cylinder that is movably hung horizontally.

[Conventional technology]

In order to sort the mixed grains of brown rice and paddy obtained through the desiliconization wind sorting process, a rotary system is used in which a receiving gutter is inserted into a sorting cylinder that has many depressions formed on the inner circumferential surface and is hung horizontally so that it can rotate. The rotary sorting rice huller combined with a sorting section is a prior art technology developed in 1982.
It is described in No. 119784.

[Problem that the invention seeks to solve]

However, the rotary sorting huller in the prior art supplies the mixed grains obtained by the desiliconization wind sorting into the sorting cylinder through a supply tank attached to the side of a cover case that houses the rotating sorting cylinder. As a result, the cover case has a shape in which the supply tank protrudes, which increases the size of the rotary sorting huller and makes the structure complicated.

The present invention aims to solve this problem.

[Means to solve the problem]

In order to achieve this object, the present invention includes a desiliconizing section and a rotary sorting section installed before and after the wind sorting section, and this rotary sorting section has the grain discharge side of the sorting cylinder adjacent to the desiliconizing section. And, in this adjacent location, the mixed grains after descaling are directly supplied into the sorting cylinder from a space formed below the paddy tank in the dehulling section.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, reference numeral a indicates a dehulling section, b a wind sorting section, and C a rotary sorting section. tank 1
and a pair of descaling rolls 2, etc., and the wind sorting section mainly winds the scraped material from the desiliconization section a at the front part, and the brown rice sorted by the rotary sorting section C at the rear part. Furthermore, it has a longer shape from front to back than the width direction for wind selection.

At the front of this wind sorting section, there are a diffusion plate 3 and a grain flow plate 4°5.6.
are arranged diagonally one after another, and the lower end of the grain board 6 looks into the main wind selection path 7 which slopes upward in the grain direction, and the lower part of this main wind selection path 7 passes through the brown rice wind selection path 8, which will be described later, and reaches the rear wall. It communicates with an open intake port 9, and the upper part communicates with a suction device 10.

Reference numeral 11 is a one-flavored food transfer gutter installed horizontally at the bottom of the main wind selection path 7, and reference numeral 12 is the Shiina wind selection path. The brown rice selection path 8 is formed on the brown rice original plate 13 and its lower side, and 14 is a waste rice removal path.

Next, the rotary sorting section C will be described. Reference numeral 15 designates a sorting cylinder having a number of depressions 16 formed in its inner circumferential surface and horizontally supporting both front and rear ends thereof so as to be rotatable by drive wheels 1, 7, and 18, respectively. This sorting cylinder 15 is installed so that its rotational axis direction is in the front-rear direction, and the supply side X of the mixed flow is at the rear and the discharge side Y is at the front. It is adjacent to.

Reference numerals 19.20 are a mixed grain transfer gutter and a brown rice receiving gutter which are horizontally suspended across the supply side X within the sorting cylinder 15, and a screw conveyor 21 is installed in each gutter 19.20.
．． 22 is installed inside, and the mixed grain transfer gutter 19 is on the discharge side Y.
A drop port 23 is opened to transfer the mixed grains from the supply side toward the supply side X, and then drop them from the supply side
is configured to be transferred from the supply side X to the discharge side Y.

Note that the bottoms of the mixed grain transfer gutter 19 and the brown rice receiving gutter 20, excluding the drop port 23, are fully opened from the supply side On-off valves 19a and 20a are respectively attached.

Reference numerals 24 and 25 designate sorting adjustment plates whose base ends are pivoted to the receiving sides of the mixed grain transfer gutter 19 and the brown rice receiving gutter 20, respectively, so that the angle of inclination can be changed.

A plurality of jump plates 26 are attached at appropriate intervals to the inner circumferential surface of the sorting cylinder 15 at the discharge side Y end. This is an annular blocking plate for preventing the grains from spilling out and promoting the jumping action.

Reference numeral 28 indicates a reducing gutter a installed inward from the side wall ca of the rotary sorting section C, and communicating with the reducing port 29 provided in the rear wall of the paddy tank 1.

Furthermore, the reference numeral 30 is a swallow for lifting the mixed grains after the desiliconization air sorting, and its lower part is connected to the above-mentioned flavor transfer gutter 11, and its upper part is connected to the paddy tank at a location adjacent to the desiliconization section a and the rotary sorting section C. 1 along the side wall ca, and the opening at the upper end penetrates this side wall ca and looks into the mixed grain transfer gutter 19.

The discharge side Y of the brown rice receiving gutter 20 communicates with the upper part of a falling path 31, and the lower part of this falling path 31 communicates with the brown rice original board 13 on one side and the grain grain board 6 on the other side by means of a switching valve 32. It is.

Note that the reference numeral 33 is a transmission section that transmits the power taken out from the gear box of the desiliconization section a to the rotational sorting section C.

Therefore, the paddy that is sequentially supplied from the paddy tank 1 is desiliconized by a pair of desiliconization rolls 2 and is air-selected in the main wind selection channel 7, and the mixed flow of brown rice and paddy after this wind selection is transferred to the first transfer gutter. The mixed flow is directly transferred from 11 by the swallow 30 [[19], is transferred toward the supply side X, and falls from the drop port 23 onto the inner circumferential surface of the sorting cylinder 15.

In addition, the grains are discharged from the shina wind selection channel 12, and the dust such as rice husks is discharged from the suction machine 10, and the mixed grains that have fallen onto the inner circumferential surface of the sorting cylinder 15 are discharged as shown in FIGS. Due to the scooping action of the recess 16 rotating in the direction indicated by arrow A in FIG. 3, the material is sorted while the flow gradually moves in the direction indicated by the arrow in FIG. 1.

In other words, brown rice, which is smaller in size than paddy, is difficult to escape from the pit 16 and is scooped up to the highest level, draws a parabola and falls into the brown rice receiving trough 20, and is not scooped up to the highest level. The remaining paddy falls into the mixed grain transfer gutter 19 and joins with new mixed grains, and the sorting action by the depression 16 is repeated again, and the unscooped paddy moves to the discharge side Y and is transferred to the jump plate 26.
The paddy is lifted up by the paddy, falls into the reducing machine 28, passes through the reducing port 29, is returned to the tank 1, and is dehulled again.

In addition, the brown rice that has flowed into the brown rice receiving channel 20 is transferred to the discharge side Y, passes through the falling path 31, and is transferred from the brown rice original plate 13 to the brown rice winding path 8.
After entering the aircraft and being screened, they are taken out to a suitable location outside the aircraft.

[Operations and Effects of the Invention] As described above, the present invention includes a desiliconization section and a rotary sorting section installed before and after the wind sorting section, and this rotary sorting section desiliconizes the grain discharge side of the sorting cylinder. Since the structure is such that the mixed grains after desiliconization are directly supplied into the sorting cylinder from the space formed below the paddy tank in the desiliconizer at this adjacent location, The structure is simpler than that in which the mixed grains after desiliconization and air sorting are fed through a supply tank in the process of supplying them to the rotary sorting section. Since the structure allows the mixed grains to be supplied directly from the space formed below, the length of the front and back of the machine can be compressed even though the paddy tank has a relatively large capacity, and the overall height of the machine has also been reduced, making it ultra-compact. This has led to improved handling properties.

In addition, in the description of the scope of claims, although reference numerals are added to the drawings, this is for the purpose of facilitating understanding and should not be construed as being limited to the structure shown in the drawings. .
