Residues can be easily removed and cleaned from open areas.

Embodiments The present invention will be explained below based on embodiment figures. The example shown in this figure is a grain rotary sorter according to the present invention incorporated into a huller to sort mixed grains of brown rice and paddy after deairing and sorting, so first we will explain the outline of this huller. let's.

A is a grain removing part, B is a wind sorting part, and C is a grain rotary sorter to which the present invention is applied, and a parting part A is placed in the front part above the wind sorting part B.
are arranged in a grain rotary sorter C at the rear, and these are integrated on a machine stand 1 to constitute a huller.

The removing section A consists of a paddy tank 2 and a pair of removing rolls 3 that rotate at different speeds below the rice tank 2, and the wind sorting section B is equipped with a suction dust remover 22 and a pressure fan 23 at the front and rear. The suction side of the fan 23 communicates with the outlet side of the pressure fan 23 to form a sorting air passage 24 on which suction air acts at the front and a sorting air passage 25 on which pressure air acts at the rear. The scraped material from the removal section A is air-sorted to remove dust and rice grains such as rice grains to obtain mixed grains of brown rice and paddy. The selected brown rice is wind sorted to remove waste rice. The grain rotary sorter C has two sorting sections in which a receiving gutter 6 and a supply gutter 7 are inserted and horizontally suspended in a sorting barrel 5 which has a large number of pot holes 4 formed on its inner peripheral surface and is rotatably hung horizontally. C1 and C2 are arranged one above the other so that the mixed grains of brown rice and paddy obtained at the front part of wind sorting section B are sorted into brown rice paddy in each of them.

Now, referring to the means of communication between the above-mentioned parts, 8 is a mixed grain distribution box, and its lower part is branched, one of which connects to the upper sorting section C1 and the supply gutter 7, and the other goes downward to the lower sorting section C2. An equalizing valve 10 with a weight 9 is provided above the branch part to distribute the mixed grains to the upper and lower supply gutters 7 while slightly storing them in the mixed grain distribution box 8. It is designed to do so. Reference numerals 11 and 12 are brown rice removal troughs, and brown rice removal trough 11 is the receiving trough 6 of the upper sorting section C1.
The brown rice removal gutter 12 communicates with this brown rice removal gutter 11.
It takes over the brown rice taken out from the screen and communicates with the receiving trough 6 of the lower sorting section C2, so that the brown rice sorted in each of them is guided onto the outflow plate 13 installed obliquely at the rear of the wind sorting section B. Numerals 14 and 15 are paddy return troughs, and the paddy return trough 14 receives the paddy flowing out from the inner circumferential surface of the upper sorting cylinder 5 and returns it to the paddy tank 2. The paddy scooped up by grain lifting buckets 16 equally distributed on the surface is received and returned to the paddy tank 2. Reference numeral 17 is a drop port for supplying mixed grains to the sorting cylinder 5 on the rear side of each supply gutter 7.

18 is a double elevator, which is the front one and is connected to the wind selection section B.
The mixed grains of brown rice and paddy obtained in step 1 are lifted up to the mixed grain distribution box 8, and the brown rice from which waste rice has been removed in wind sorting section B is lifted up and placed in a suitable place outside the machine. It is supposed to be taken out. In addition, 19 is a mixed grain takeout gutter that supplies mixed grains to the front side of the double elevator 18, 20 is a brown rice takeout gutter that supplies brown rice to the rear side of the machine, and 21 is the waste rice taken out of the machine. This is the waste rice removal gutter.

Next, the configuration of the main parts of the present invention will be described. Since the upper and lower sorting sections C1 and C2 have the same configuration, the upper sorting section C1 will be explained and the lower sorting section C2 will be omitted. .

The supply gutter 7 of the receiving gutter 6 has its front side, that is, the other end, supported in a cantilever manner on the front wall a of the grain rotary sorter C, and its free end, which is the rear end, as shown in FIGS. 5 and 6. As shown in the figure, the circular plate is integrally fixed to a support plate D whose upper and lower sides are both open with notches. Therefore, the shaft ends of the screw conveyors 42 and 43 installed in the receiving gutter 6 and the supply gutter 7 are inserted through and supported by the support plate D, and the fulcrum shaft end of the gate valve 26 is also inserted into the support plate D. supported. The rear wall b of the grain rotary sorter C has a large opening large enough to allow the sorting cylinder 5 to be inserted and removed, and the outer peripheral edge 27 is joined to this opening, and the inner peripheral edge 28 is joined to the support plate body D except for the open part. One end side, which is the free end side, of the support plate D in a cantilevered state is firmly supported via the lid E. On this occasion,
The lid body E is fixed to the rear plane wall b and the support plate body D by several knob screws 29.

As shown in FIGS. 3 and 4, on the lid E, a roller 41 made of rubber or the like protrudes inward from a location biased toward the sorting cylinder 5, which rotates in direction A in FIG. The rolling surface 30 of the sorting cylinder 5 is pressed from above to suppress the vibration of the rotating sorting cylinder 5 supported by a plurality of drive wheels 31.

Further, the peripheral edge of one end of the sorting barrel 5 through which the mixed grains are supplied from the drop port 17 of the supply gutter 7 is bent toward the rotational axis of the sorting barrel 5 to form an overflow prevention wall 32. However, an elastic annular body 34 made of rubber, on which the tongue piece 33 is integrally molded, is integrally fitted to the inner peripheral edge of the overflow prevention wall 32.

Furthermore, a cylindrical flange 35 is integrally attached to the lid E, the outer circumferential surface of which is joined to the tongue piece 33 of the elastic annular body 34 and is slightly tightened.

Note that 36 and 37 are support rails on which the sorting cylinder 5 is slid when being inserted or removed from one end side.

In the diagram shown in FIG. 10, a transparent plate member 38 and an opaque plate member 39 are respectively attached to the open parts formed above and below the support plate D to close the open parts,
This shows an example in which a box-shaped cover 40 is then attached to cover the shaft ends of the screw conveyors 42 and 43 and the fulcrum shaft end of the gate valve 26, and a transparent plate body is used instead of the opaque plate body 39. It's also good.

Therefore, from the operable state shown in Figs. 1 and 2, the knob screws 29 are removed and the lid body E is pulled out rearward, resulting in the state shown in the upper part of Figs. 7 and 8, and the sorting cylinder is further removed. 5 to support rail 36,
37 and pull it out, it will be disassembled into the state shown in the lower diagrams of FIGS. 7 and 8. Also, from this state, if the sorting cylinder 5 is inserted and the procedure is reversed to the above, the machine is ready for operation.

Effects of the Invention As described above, the present invention has a number of pot holes formed in the inner circumferential surface, and a receiving gutter is inserted horizontally into the sorting cylinder, which is rotatably hung horizontally, and the water is mixed in the sorting cylinder. In a grain rotary sorter that sorts grains by making them flow, the support plate that supports one end of the receiving gutter is configured so that both the upper and lower parts of the supported part are open. Both the upper and lower sides of the receiving trough inside the shell can be observed from the outside through the open points mentioned above, allowing the operator to use it with confidence while visually confirming it.Furthermore, when the sorting work is completed, this is opened. It has features that allow easy removal and cleaning of residue from the site.

Moreover, if the receiving gutter etc. is made cantilever type as in the embodiment of the present invention, and the sorting cylinder is configured to be freely inserted and removed and disassembled, it is possible to completely remove and clean the residue, but during operation, it is cantilevered type. While the receiving trough and the like are firmly supported by the support plate, the inside of the sorting cylinder can be observed through the open portion thereof.
