(2) I am correcting the entire text of the specification (in the attached sheet). (3) All 9 drawings will be corrected as shown in the attached sheet. Description 1, Title of the invention 1 Rotary grain sorting device 2, Claim 3, Detailed description of the invention [Field of industrial application] The present invention is directed to, for example, mixed rice of paddy and brown rice after hulling. This invention relates to a rotary grain sorting device used to sort brown rice from brown rice. [Prior Art] A rotary sorting cylinder having a number of concave portions formed on its inner peripheral surface is installed horizontally, and one end of the rotary sorting cylinder is placed on the supply side of mixed rice of paddy and brown rice, and the other end is placed on the side where mixed rice of paddy and brown rice is supplied. A rotary grain sorting device is disclosed in Japanese Patent Application Laid-Open No. 2003-120000 as a prior art, in which a brown rice receiving trough is arranged in the rotary sorting tube and extends in the axial direction of the sorting tube. This is disclosed in Publication No. 49-24746. This rotary grain sorting device repeats the flow in which the mixed rice supplied to the feeding side at one end of the sorting tube is sown up to a height created by the rotation of the sorting tube, and then falls to the bottom, forming a fluidized bed. During the transfer of the mixed rice to the discharge side of the other part 1 while forming, the brown rice of the mixed rice is lifted up to a relatively high position while being stuck in the fourth part, and then falls, and the paddy of the mixed rice is transferred to the discharge side of the other part 1. By utilizing the movement of falling from a lower position than brown rice, the brown rice falling from a higher position is received by a brown rice receiving gutter and taken out. In this case, the sorting device of the prior art is capable of Sorting the tubes↑,
? I' so that the discharge side that affects i is lower than the supply side.
I am proposing to do IJi21. [Problem that the invention attempts to solve] As in this prior art, the separate jγ cylinder is arranged so that the discharge side of the separate cylinder is lower than the supply side (if it is tilted, the separation cylinder will be closed at the end of the sorting operation). By continuing the rotation of the rice for a while, the mixed rice remaining in the sorting cylinder can be discharged from the discharge side. If the angle is set too large, the time required to discharge the residual mixed rice in the sorting cylinder at the end of the work can be shortened, but on the other hand, the supply of the sorting cylinder (
The transfer speed of the mixed rice supplied to the discharge 1jjll becomes faster, and the thickness of the fluidized bed of mixed rice in the sorting cylinder becomes thinner as a whole (as the sorting cylinder rotates). A flying and/or dancing phenomenon in which the mixed rice that falls after being scraped up to a height tries to fit into the recess at the bottom of the sorting tube, or the brown rice that has been fitted in the recess is pushed out of the recess. becomes larger and the number of brown rice that fits into the recess decreases, resulting in a decrease in brown rice sorting ability and sorting accuracy.Furthermore, if the inclination angle of the sorting cylinder is set to a support angle close to horizontal; During separate operations, the speed at which the mixed rice in the sorting cylinder is transferred to the discharge side is slow, and while the thickness of the fluidized bed of mixed rice can be maintained thick, it takes a long time to discharge the residual mixed rice in the sorting cylinder at the end of the operation. In other words, the inclination of the sorting tube conflicts with shortening the time for discharging the residual mixed rice in the sorting tube and improving the ability and accuracy of sorting brown rice. The device cannot satisfy both of these requirements. The present invention solves this problem. [Means for solving the problem] Therefore, the present invention provides a recessed portion on the inner circumferential surface. A rotary sorting tube having a plurality of recesses is installed horizontally, one end of the rotary sorting tube is configured as a supply side for mixed rice of paddy and brown rice, and the other end is configured as a paddy discharge side. In a rotary grain sorting device comprising a brown rice receiving trough that extends in the axial direction of the sorting tube in a rotary sorting tube, the rotary sorting tube is arranged such that its discharge side is lower than its supply side. [Operations and Effects of the Invention] By configuring the sorting tube so that its inclination can be adjusted so that the discharge side is lower than the full supply, the sorting tube can be adjusted easily during sorting work. Since the inclination angle of the sorting cylinder can be set at a gentle angle close to horizontal or horizontal, the ability and accuracy of sorting brown rice can be maintained at a high level.However, at the end of the sorting work, the inclination angle of the sorting cylinder can be increased. Therefore, the residual mixed rice in the sorting cylinder can be easily discharged in a short time.Therefore, according to the present invention, the time for discharging the residual mixed rice in the sorting cylinder can be shortened, and the power for sorting brown rice can be reduced. Both of this and the improvement of sorting accuracy can be easily achieved by adjusting the inclination of the sorting tube.Moreover, by configuring the sorting tube so that its inclination can be adjusted so that its discharge side is lower than its supply side,
It has the effect that the sorting ability and sorting accuracy of brown rice can be arbitrarily adjusted depending on the variety and/or moisture content of grains to be handled, the feeding type in the sorting cylinder, etc. [Example] Hereinafter, an example in which the present invention is applied as a brown rice sorting device in a hulling sorting machine will be described. Fig. 1 shows a side view of the entire hulling sorting machine, and the hulling sorting machine has the following steps: It is configured such that a hulling device F having a hopper 9 and a culm removal roll 10 and a rotary sorting device C are mounted on the top surface of a long and narrow wind sorting box E.

The rotary sorting device C includes a primary sorting tube A and a secondary sorting tube a that are horizontally arranged in upper and lower stages in a box-shaped case C', and both of these sorting tubes A and a are open-ended at both ends. A large number of recesses 1 large enough to fit brown rice are formed on the inner peripheral surface thereof, and both sorting cylinders A, a have a side closer to the hulling device F facing the discharge side Y, The side farther from the hulling device F is the supply side
Each of these is composed of: Furthermore, of both the sorting tubes, the primary sorting tube A has its supply side X connected to the box-shaped case C'.
The secondary sorting cylinder is placed on a pair of rollers 31, 31 protruding from the inner surface, and is supported by fixing the discharge side Y to a rotating shaft 19 mounted approximately horizontally on a box-shaped case C'. a is placed on a pair of rollers 31, 31 with the lower outer periphery of the discharge side Y protruding into the inner surface of the box-shaped case C', while the supply side X is placed approximately horizontally on the box-shaped case C'. It is supported by being fixed to a mounted rotating shaft 20. Inside the secondary sorting tube A, there is an open-top brown rice receiving trough B extending in the axial direction of the sorting tube, with both ends of the brown rice receiving trough B extending in the axial direction of the sorting tube. This brown rice receiving channel B is provided so as to be fixed to the case C'.
A spiral conveyor 21 formed on the rotating shaft 19 is provided inside. Further, in the secondary sorting tube a, there is a brown rice receiving trough with an open top surface extending in the axial direction of the sorting tube,
Both ends thereof are fixed to the box-shaped case C', and a spiral conveyor 22 formed on the rotating shaft 20 is provided within this brown rice receiving trough. Note that both brown rice receiving troughs B and b are provided with rotary adjustment partition plates 23 and 24, respectively. A popper 25 for feeding the mixed rice from the mixed rice thrower 7 into the primary sorting section A is provided on the outer surface of the supply side X of the box-shaped case C'. A receiving gutter 26 is provided on the discharge side Y for guiding the paddy discharged from the discharge side Y to the primary sorting tube to the hopper 9 in the hulling device F. Further, the outlet end of the brown rice receiving channel B in the secondary sorting tube A is connected to the secondary sorting 'i'i? The discharge side Y of the secondary sorting tube a communicates with the inside of the supply side The passage 29 and shoe l
30 to the brown rice conveyor 6, respectively. A transmission case 32 is fixed to the lower surface of the supply side X of the box-shaped case C', and both ends of a transmission shaft 33 that passes through the transmission case 32 and is pivotally supported are connected to the wind selection box E.
The box-shaped case C' is configured such that the discharge side Y moves up and down about the transmission shaft 33 by being pivotally supported on the left and right side plates 2, 2 of the box via bearings 34, 35. A mechanism for adjusting the inclination angle of the sorting tube is provided between the discharge side Y of the mold case C' and the omper 9 of the hulling device F. This adjustment mechanism is constructed as shown in FIG. That is, a support frame 45 is fixed to the upper surface of the hopper 9 of the hulling device F with bolts 46, and a shaft rod 48 having a slot 47 at one end is attached to the support frame 45 in the axial direction of the sorting cylinder A, a. A truncated cone-shaped stopper pin 49 is fixed to the other end of the shaft rod 48, and the stopper pin 49 is connected to the shaft rod 48 by a spring 50 that is fitted to the rotary type. While urging the rotary sorting device C to project in the direction of the sorting device C, the side 1 on the discharge side Y of the box-shaped case C' of the rotary sorting device C is
1, a plurality of bottle holes 52 into which the stopper pins 49 are fitted are bored at appropriate intervals in the vertical direction, and the stopper pins 49 are inserted into the bottom pinned holes 52 of the respective bottle holes 52. When fitted, both sorting tubes A, a are approximately horizontal, and when inserted into the upper bin hole 52, both sorting tubes A, a are tilted so that the discharge side Y is lower than the supply side X. It is configured. A pulley 36 fitted to one end of the power transmission shaft 33, which is a pivot point for the rotary sorting device C with respect to the wind sorting box E, has a pulley 36 fitted to one end thereof.
A transmission case 32 transmits power from the belt 3B from the boot 1J37 in the brown rice conveyor 6 and accommodates the transmission shaft 33.
Power is transmitted from a transmission shaft 33 in a transmission case 32 via a worm gear 40 to a shaft 4 projecting rearward from the shaft 4, and from a pulley 39 fitted on the shaft 4, both sorting cylinders A are connected. By transmitting the bell 1-44 to the pulleys 42 and 43 at the ends of the rotating shaft 19 and 20 at a, both sorting tubes A are separated. A is configured to rotate at an appropriate speed in the direction shown by arrow (A) in FIG. Therefore, during the dehulling and sorting work, by fitting the stopper pin 49 of the inclination angle adjustment mechanism of the sorting tube into the bottom bin hole 52, both the sorting tubes A and a are placed in a substantially horizontal state, and the rice grain is removed. When paddy is supplied to the flopper 9 in the device F, the mixed rice deculled in the hulling device F collects suction dust ta3 while flowing down to the mixed rice conveyor 5.
After the rice husks are sorted and removed by the suction air, the mixed rice is supplied from the mixed rice conveyor 5 to the supply side X in the secondary sorting cylinder A via the mixed rice thrower 7 and the bomber 25. The mixed rice thus supplied into the next sorting tube A is
- After being lifted up to the height determined by the rotation of the secondary sorting tube A, the flow of falling to the bottom is repeated, forming a fluidized bed and being sequentially transferred toward the discharge side Y as shown by the arrow (b) in Figure 2. Ru. During this fluid transfer, the brown rice in the mixed rice is lifted up to a relatively high place while being fitted in the recess 1, and then
Brown rice mainly enters brown rice receiving channel B by falling from the brown rice receiving channel B. Then, after the brown rice is removed in the primary sorting section A so that it enters the brown rice receiving channel B as described above, the mixed rice is transferred to the discharge side Y.
The amount of paddy increases as the paddy is transferred to, and enters the hopper 9 in the hulling device F from the discharge side Y via the receiving gutter 26, where the dehulling action is performed again. On the other hand, the brown rice that has entered the brown rice receiving channel B in the secondary sorting tube A is transferred by the rotary conveyor 21 in the direction shown by the arrow (c) in FIG.
It is supplied to the supply side X in the secondary sorting cylinder a through the filter 1-27, where it is again sorted. That is, the brown rice supplied into the secondary sorting tube a flows as described above and is transferred toward the discharge side Y as shown by the arrow (bo) in FIG. After being sorted to enter the brown rice receiving trough, it flows out from the discharge side Y to the mixed rice conveyor 5 via the shoe I.28.
While repeating the circulation of being sent to the secondary sorting tube A again,
The brown rice that has entered the brown rice receiving trough is transferred to the second rotary conveyor 22.
After being sent in the direction shown by the arrow (d) in the figure, it flows down to the brown rice containers 1 and 6 via the passage 29 and chute 30.
The brown rice is taken out of the machine by a brown rice wafer 8 connected to the brown rice conveyor 6. When the hulling and sorting work as described above is completed, the mixed rice remaining at the bottom of both sorting tubes A and a must be discharged.
