A rectangular porous wall sorting plate 1 having a corrugated surface 2 is tilted, and a complete grain outlet 4 and a damaged grain outlet 6 are provided on one side of the lower end of the inclination, sandwiching a mixed grain outlet 5. A ventilation chamber 7 is formed above this porous wall sorting plate 1, a raw material supply port 3 is provided near one side, and a ventilation chamber 8 is integrally provided below the ventilation chamber 7 to form a sorting machine frame 9. form. The sorter frame 9 is swingably supported above the wind turbine box 11 fixed to the underframe 22 by fasteners 23, and this support device will be explained below.

A wind tunnel section 36 is fixed to approximately the center of the ventilation chamber 8 at the bottom of the sorter frame 9, and the lower end of the wind tunnel section 36 is slidably connected to the discharge port at the upper end of the wind turbine box 11. A pair of fixing plates 19 and a pair of fixing plates 25 are fixed to both sides of the wind turbine box 11, and the fixing plates 19 and 25 on one side are fixed to each other.
The crankshaft 24 is rotatably supported through the crankshaft 24, and the crankshaft 24 has a U-shaped horizontal arm rod 14.
Pivotally support both ends of. As a result, the horizontal armrest 1
4 is provided around the wind turbine box 11 so as to be rotatable around the fixed plate 19 side, and this rotating side is supported by one of the fixed plates 25 via an angle adjustment device 26. That is, the rotating handle 35 with a rotating shaft protruding in the horizontal direction is connected to a rotating mechanism 32 having a built-in bevel gear.
The adjusting screw shaft 33 is supported by the fixed plate 25 through a nut portion 34, and a horizontal frame-like structure is attached to the upper end of the rotating mechanism 32, which moves up and down by turning the handle 35. Mount the arm rod 14.

In this way, the lower supports 15 and 16 of the elastic support rods 17 and 18 made of leaf springs or the like are fixed to the front and rear arms of the horizontal arm rod 14 supported by the wind turbine box 11, respectively. Each upper fulcrum 12 and 1 of
3 is fixed to the bottom of the sorting machine frame 9. Further, a pulley is provided at one end of the crankshaft 24 to interlock and connect with the motor, and a crank arm is formed at the other end, and this end is supported by the crank bearing 20. and sorter frame 9
are connected by rod 21, thereby
A swing mechanism 10 is formed.

An elevator 29 is attached to the wind turbine box 11 on the underframe 22.
A supply hopper 30 is installed at the lower part of the elevator 29, and a grain tank 31 is installed at the upper part, and the lower end of the supply hopper 31 faces the supply port 3 of the sorter frame 9. In addition, air intake ports are opened in the front and rear walls of the wind turbine box 11, and a side plate 27 is attached near each air intake port, and a blade axle 28 is pivotally supported on the side plate 27.

Next, specific operations in the above embodiment will be explained. Raw material grains, for example, legumes such as soybeans, are charged from the supply hopper 30 and are supplied to the supply port 3 of the sorter frame 9 via the elevator 29 and grain tank 31. The beans falling from the supply port 3 onto the porous wall sorting plate 1 spread over almost the entire surface of the sorting plate 1 to form a fluidized bed, and are also used for the shaking action by the swinging mechanism 10 and by the blowing air from the wind turbine box 11. The specific gravity is selected by the action. That is, due to the moderate wind blowing up from the ventilation chamber 8, complete grains with high specific gravity sink to the lower layer of the fluidized bed, and incomplete grains with low specific gravity (damaged grains, half-split grains, etc.) float relatively to the surface layer. Therefore, the complete grains in the lower layer are shaken up by the wave-like surface 2 and drift toward one side (higher inclined side) of the porous wall sorting plate 1, forming a complete grain flux P, and the unfinished grains floating on the surface layer are The perfect grains slide over the perfect grains and drift toward the other side (lower slope side) of the porous wall sorting plate 1 to form a damaged grain flux R. Then, the complete grain flux P and the damaged grain flux R
A mixed grain flux Q is formed between
The grains fall through the complete grain outlet 4, mixed grain outlet 5, and damaged grain outlet 6 provided at the lower end of the slope and are taken out of the machine.

In this way, sorting is carried out, but the fluidity state on the porous wall sorting plate 1 changes depending on the variety of raw legumes and the moisture content, but in this case,
The angle of inclination perpendicular to the inclination (fixed) toward each of the discharge ports 4, 5, and 6 is adjusted by the angle adjustment device 26. That is, by rotating the rotary handle 35 in the normal or reverse direction, the adjusting screw shaft 33 is moved into the nut portion 34.
The horizontal arm rod 14 is rotated about the crank shaft 24 via a rotating mechanism 32 fixed to the upper end of this screw shaft 33, and sorted together with the elastic support rods 17, 18 and rods 21. The inclination angle of the machine frame 9 is changed to adjust to the optimum sorting condition.
