It is an object of the present invention to provide a high-performance mixing ratio adjusting device for a vertical sorting device that has a simple structure and can reliably adjust the mixing ratio of fine particles to be sorted by simple operation.

Composition of the Invention The mixing ratio adjustment device for a vertical sorting device of the present invention has a porous wall sorting tube rotatably mounted inside a vertical machine frame, and a spiral body fitted in the sorting tube is rotated or reciprocated. A mixing ratio adjusting cylinder is connected to a rotating drive device and is mounted on the sorting cylinder to adjust the mixing ratio of fine particles such as immature grains, and the adjusting cylinders are fitted into each other in a column and moved up and down. It has a structure characterized in that it is formed by a plurality of adjustable cylindrical bodies.

DESCRIPTION OF EMBODIMENTS The structure of the present invention will be explained based on FIGS. 1 to 4.

FIG. 1 shows a vertical sorting and weighing device for grains, which is constituted by a vertical sorting device 1 consisting of a sorting rotary body 2 and a grain lifting device 4 on which a grain sizing tank 3 for weighing is suspended.

The vertical sorting device 1 (see Fig. 1) has a sorting rotating body 2 erected inside a vertical machine frame 7 which has a supply hopper 5 in the upper part and a grading discharge port 6 in the lower part. The sorting rotor 2 is attached to a vertical shaft 8, and is integrally formed by fitting a spiral body 9, which is formed by winding a spiral blade, into a porous wall sorting tube 10.
A grading and scraping impeller 11 is attached to the lower end of the sorting tube 10 and rotates integrally, and the rotation of the impeller 11 removes grading from the inner bottom of the sorting tube 10 from the grading discharge port 6. Channel 12
A driving device 13 for rotating or reciprocating is connected to the vertical shaft 8, and a fine particle chamber 14 is provided around the porous wall sorting tube 10. By rotation, immature grains, crushed grains, etc. at the bottom of the fine grain chamber 14 are discharged from the fine grain discharge gutter 16, and the illustrated sorting cylinder 10 and spiral body 9 are formed to rotate at different speeds in the direction of the copper position. It is.

Reference numeral 17 denotes a mounting fitting for attaching and detaching the supply hopper 5 portion provided on one side wall surface of the vertical machine frame 7.

Next, a mixing ratio adjusting cylinder 18 for adjusting the mixing ratio of fine particles such as immature particles (meaning the removal rate of fine particles) is mounted on the porous wall sorting cylinder 10, and (see FIGS. 2 and 3) (See figure) The adjustment cylinder 18 is formed by a plurality of cylinders 19A, 19B, and 19C that are fitted into each other in a vertical line and arranged in a row so as to be vertically adjustable, and 20 is the bottom cylinder 19G. An annular blocking plate connected to the lower end, 21 an annular locking portion provided at the upper end of the uppermost cylinder 19A, 22 each cylinder 19A, 198.1
9, 23 is a screw shaft for attaching the annular blocking plate 20 and the annular locking part 21, 24 is a cleaning body in FIG. 1, and 25 is a sorting device and a grain frying device. It is a connecting fitting.

The operation of the above configuration will be explained below.

Mixed grains (mixture of fine grains such as immature grains and crushed grains and regular grains)
When the mixed grains are supplied to the supply hopper 5 of the vertical sorting device 1 and the device is started, the porous wall sorting cylinder 10 and the spiral body 9 rotate in the same direction at different speeds, so that the mixed grains are transferred from the supply hopper 5. The grains flow down and flow onto the spiral blades of the inclined spiral body 9 to form a grain layer, and each grain receives a centrifugal force due to contact with the rotating spiral blades.The porous wall sorting tube 10
The fine grains are biased toward the surface and dispersed in a scattering manner, and the small fine grains are discharged to the outside through the holes of the porous wall sorting tube 10, and the large grains are distributed to the surface of the sorting tube 10. When they come into contact with each other, the contact force causes them to drift in the opposite direction in a revolution-like and avalanche-like manner, and the fine grains that are mixed in with the replaced grains due to this drift in the opposite direction are then biased by the centrifugal force, causing them to drift in the same way as described above. The grains are discharged from the through hole and flow down inside the fine grain chamber 14, and the grains on one side of the spiral blade gradually move obliquely downward due to the rotational force of the spiral body 9 and rotate while rotating inside the sorting rotor 2. The grains accumulate at the bottom of the body 9, are transported by the impeller 11, and flow from the grading discharge port 6 to the feed port of the grain lifting device 4 via the flow path 12. Further, the fine grains accumulated at the bottom of the fine grain chamber 14 are conveyed by the blades 15 and are discharged from the fine grain discharge gutter 16 to the outside of the machine.

Next, when adjusting the mixing ratio of small particles such as fine particles (immature particles and crushed particles) to be sorted, (see Fig. 2).

(See Figure 3) Open the upper supply hopper 5 section by operating the attachment fittings 17 provided on the vertical machine frame 7, and then loosen the connecting fasteners 22 as appropriate to achieve the mixing ratio. Adjustment tube 18
is lowered along the surface of the porous wall sorting tube 10, and the porous wall sorting tube 1
The 0 sorting surface is regulated to a closed state with an arbitrary predetermined adjustment area (meaning the passing area according to the mixing ratio based on experimental values), and the mixing ratio adjustment cylinder 18 is connected to the connecting fastener 22... When the operation is continued after being tightened and fixed, the amount of fine particles flowing out from the holes of the porous wall sorting tube 10 whose sorting surface has been reduced and the length of the sorting process has been corrected is adjusted accordingly. Some of the fine particles are mixed into the sized particles, and the sized particles having an arbitrary predetermined mixing ratio of fine particles are discharged from the sized particle discharge port 6 through the flow path 12 to the outside of the machine.

In FIG. 1, the sorted grains taken out from the vertical sorting device 1 are stored in a grain frying device 40 and a weighing grain tank 3 suspended from the upper side of the machine.
The grains are fried and temporarily stored in a container, and a predetermined weight of grains is automatically discharged by opening and closing an automatic discharge valve 27 connected to a weighing device 26, and then packed into a container or the like.

FIG. 4 shows a case where fine particles remaining in the cylinder body 19C of the mixing ratio adjustment cylinder 18 are removed. When the screw shaft 23 fastened to the annular shielding plate 20 is loosened and lowered, the gap Any residual fines can be easily removed and cleaned.

The sorting tube and the mixing ratio adjusting tube are formed into cylindrical bodies, polygonal tubes, etc., and the connecting fastening fittings and the like are not limited to the structure shown in the drawings, and any general connecting fastening means can be used. Selected and used. Further, the cleaning body is formed of an elastic material such as rubber, plastic, bushing, etc. into a blade wheel or blade piece.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, as described in detail, the mixing ratio adjusting cylinder consisting of a plurality of cylinders is provided on the porous wall sorting cylinder so as to be able to move up and down, thereby adjusting the sorting area of the porous wall sorting cylinder as appropriate. By adjusting the increase/decrease, the mixing ratio of the fine particles to be sorted can be reliably adjusted with a simple adjustment operation.The simple structure also simplifies the installation of the mixing ratio adjustment cylinder and reduces its manufacturing cost. It has effects such as being able to reduce the cost, carry out an effective sorting action, and reliably and smoothly mass-produce grains with an arbitrary predetermined fine grain mixture ratio.
