A driving shaft is passed through the wind turbine case, and both ends are protruded from the left and right sides of the case, and the tips of the left and right rods of the adjustment frame, which is U-shaped when viewed from above, are attached to both ends. The perforated sorting plate is supported by a diagonal rod protruding from the adjustment frame. The eccentric wheel attached to one end of the shaft and the sorting perforated plate are connected by a rod, so that when the shaft is driven, the motion of the eccentric wheel is transmitted to the sorting plate via the rod, and the perforated sorting plate is said to swing diagonally up and down.

[Problem that the invention seeks to solve]

By the way, in the above-mentioned grain sorting device, a driving shaft is passed through the wind turbine case, and an adjustment frame is rotatably mounted on both ends of the shaft, and an eccentric wheel is provided, making it easy to assemble the swinging mechanism. Not. In other words, it is easy to mount on the shaft an eccentric ring which is integrally formed with an adjustment frame that supports the lower end of the diagonal rod that supports the perforated screening plate, which has a considerable weight, and a rod that provides rocking motion to the perforated screening plate. Furthermore, it is difficult to assemble or repair items provided within the wind turbine case, such as a balance weight that is normally provided on the shaft. This becomes even more noticeable when the sorting machine is a large model.

In view of this point, it is a technical object of the present invention to provide a rocking device for a grain sorter that can be easily assembled or repaired even if it is a large model.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a porous wall sorting plate having a wavy surface, which is inclined, an outlet is provided at the lower end of the inclination, and an outlet is provided above near the upper end of the inclination. A supply port is provided, and a ventilation chamber communicating with the wind turbine is provided below the sorting plate to form an integral sorting machine frame, and this sorting machine frame is mounted on a U-shaped support frame via a support rod. , a grain sorter comprising an angle adjustment device on one side of the closed side of the support frame for tilting the sorter frame in a direction substantially perpendicular to the inclination direction; Fixed to.

(b) The angle adjusting device is connected to the outside of one side of the wind turbine box, and the rotating shaft is rotatably horizontally supported on the outside of the other side by bearings fixed to a pair of fixed plates.

(c) On the other hand, both ends of the support rod are made into half-shaped support parts, and the half-shaped support parts are rotatably attached to the outer circumferential wall of each bearing.

Furthermore, one end of the rotating shaft is fitted into the shaft hole of the eccentric cam pulley, and the eccentric shaft protruding from the eccentric cam pulley and the sorting machine frame are connected by a connecting rod.

This technical measure was taken.

[Effect]

As a result, the closed side of the U-shaped support frame on which the sorter frame is mounted via the support rods is supported by one side of the wind turbine box outside through the angle adjustment device, and both ends of the support frame are supported by half-shaped supports. The part of the wind turbine box is rotatably supported by the bearing outer peripheral wall of the rotating shaft horizontally suspended outside the other side of the wind turbine box, so the angle of inclination of the sorter frame can be adjusted around both ends of the support frame by operating the angle adjustment device. (H-L direction in Fig. 3). In addition, since the eccentric shaft protruding from the eccentric cam pulley mounted on one end of the rotating shaft and the sorting machine frame are connected by a connecting rod, the sorting machine frame is given swinging action, and this swinging action and Due to the wind blowing up from below the sorting plate, the particles with relatively high specific gravity in the grain are thrown up by the wavy surface (H side in Figure 3), and the particles with relatively low specific gravity are placed on top of the particles with high specific gravity. The particles rise to the surface and flow down the slope (L side in Figure 3), and then, along with this drifting action, flow down to the outlet provided at the other bottom of the slope, where they are taken out of the machine in a sorted state. . Furthermore, when attaching and detaching the support frame or the rotation shaft during assembly or repair, only the support frame or only the rotation shaft can be removed separately.

The sorting machine frame 9 is swingably supported above the wind turbine box 11 fixed to the underframe 28 with fasteners 32, and this swinging device will be explained next.

A wind tunnel section 12 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 12 is slidably connected to the discharge port at the upper end of the wind turbine box 11. A pair of fixing plates 13 and a pair of fixing plates 14 are fixed to both sides of the wind turbine box 11, and fixing plates 13 and 14 on one side,
The shaft 13 passes through a rotation shaft 15 and is rotatably supported by bearings 10, 10, and both ends of a support frame 16 having a U-shaped planar shape are pivotally supported by the bearings 10, 10.
That is, the bearing 1 supports the shaft end portions 15a, 15a and is fixed to the fixed plates 13, 13 with bolts.
0 and 10 (see FIG. 4) are half-split support portions 17A and 17B formed at both ends of the support frame 16, respectively.
is rotatably supported. One side of the half-shaped support part 17
A is welded to each end of the support frame 16, and this support part 17A and the other half-shaped support part 17B form the bearing 10.
It embraces and provides support. As a result, the support frame 16 is placed around the wind turbine box 11, and the fixing plate 3
The rotation side is supported by one fixed plate 14 via an angle adjustment device 18. In other words, the angle adjustment handle 1 has a rotating shaft protruding horizontally toward the front side.
9 is connected to the adjustment screw shaft 21 via a rotational direction conversion mechanism 20 incorporating a bevel gear, and the adjustment screw shaft 2
1 is supported by a fixed plate 14 via a nut portion 21a, and a support frame 16 is mounted on the upper end of a rotational direction changing mechanism 20 that moves up and down by turning this handle 19.

In this way, each lower fulcrum of the support rod 22 is pivotally connected to the support frame 16 rotatably provided on the wind turbine box 11, and each of the upper fulcrums is formed to support the bottom of the sorter frame 9. Further, an eccentric cam pulley 23 is pivotally attached to one end of the rotating shaft 15. That is, the shaft end 15a of the rotating shaft 15 passing through the bearing 10
is fitted into the shaft hole 24 in the center of the eccentric cam pulley 23, and the eccentric shaft 25 on the opposite side, which projects eccentrically, has a connection whose upper end is pivoted to the sorting frame 9 and serves as a force application point. The lower end of the rod 26 is pivotally mounted (bearings etc. are not shown). Further, a balance weight 27 is integrally provided on the eccentric cam pulley 23, and a balance weight and a connecting rod (not shown) may also be provided at the other end of the rotating shaft 15.

An elevator 29 is attached to the wind turbine box 11 on the underframe 28.
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 grain tank 31 faces the supply port 3 of the sorter frame 9. In addition, air intakes are opened in the front and rear walls of the wind turbine box 11, and a side plate 33 is attached near each air intake.

It is connected to a motor pulley of an electric motor 28 via a deceleration pulley 36 by a V-belt.

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 shaking by the shaking device and from the discharge port of the windmill box 11. Gravity sorting is carried out by the action of blast air. In other words, due to the moderate wind blowing up from the ventilation chamber 8, complete grains with relatively 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, so the complete grains in the lower layer are shaken up by the wavy surface 2 and drift toward the higher slope side H of the porous wall sorting plate 1, resulting in a complete grain flow. The incomplete grains that form a bundle P and float to the surface layer slide over the complete grains and pass through the porous wall sorting plate 1.
The damaged particle flux R is biased toward the lower slope side L of the particle. A mixed grain flux Q is formed between the complete grain flux P and the damaged grain flux R, and a complete grain discharge port 4 and a mixed grain discharge port are respectively provided at the lower end of the slope in the other slope direction. 5 and the damaged grain outlet 6 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 18. That is, by rotating the rotary handle 19 in the forward or reverse direction, the adjusting screw shaft 21 can be adjusted to the nut portion 21.
The support frame 16 is rotated about the bearings 10, 10 of the rotary shaft 15 via the rotation direction changing mechanism 20 fixed to the upper end of the screw shaft 21, and the sorting machine is moved together with the support rod 22. The inclination angle of the frame 9 is changed to adjust to the optimum sorting state.

〔Effect of the invention〕

As described above, according to the present invention, remarkable effects as described below are achieved.

A. A wind turbine box containing a wind turbine is fixed to an underframe, an angle adjustment device and a rotating shaft are provided on both sides of the wind turbine box, and half-split supports are formed at both ends of the support frame on which the sorting machine frame is placed. Since the support frame is rotatably attached to the outer peripheral wall of the shaft bearing, and the other side of the support frame is connected to the angle adjustment device, the entire rocking device is attached to the outside of the wind turbine box, making it easy to inspect and inspect the rocking device. Repairs are easier, and the weight can be reduced compared to a case in which a wind turbine box is built in and the rocking device is supported in this case.

B Furthermore, since the half-shaped support parts at both ends of the support frame are supported by bearings fixed to the fixed plate, the support frame can be removed without removing the rotating shaft, and the support frame can be left in its original state. It is possible to replace only the rotating shaft. Also, during assembly, the support frame and the rotating shaft can be assembled in separate steps without being performed at the same time, so much manpower is not required.
