(Prior art) Conventionally, a humidity control tank for controlling the humidity of grains was installed at the top, a down-flow drying chamber for drying the grains was installed at the bottom, and an elevator was installed at the side. In a case where a supply conveyor for transferring to the center of the humidity control tank is installed horizontally, the axial direction of the upper roll of the conveyor belt of the elevator is parallel to the axial direction of the supply conveyor, and the axial direction of the upper roll of the conveyor belt of the elevator is parallel to the The starting end of the supply conveyor is located at the grain discharge end position, an inlet is opened at the bottom of the discharge gutter, a thrower is attached to the bottom of the inlet, and the axial direction of the grain lifting blade of the thrower is aligned with the supply conveyor. An example of parallel to the axial direction is described in Japanese Utility Model Application Publication No. 53-29964.

(Problems to be Solved by the Invention) The problem with the known example is that the starting end of the supply conveyor is located at the grain discharge end position of the discharge gutter of the elevator, and the inlet is opened at the lower part of the discharge gutter.
A thrower is attached to the lower part of the inlet, and the axial direction of the grain frying blades of the thrower is parallel to the axial direction of the supply conveyor. Therefore, the grains flow into the thrower under their own weight, but in the case of the thrower, since the thrower itself has almost no power to suck in the grains, there is a risk of grain clogging if the known structure is used.

(Means for solving the problem) Therefore, the present invention provides a humidity control tank 1 for controlling the humidity of grains.

The axial directions of the conveyor 18 are parallel to each other, the starting end of the supply conveyor 18 is located at the lower end of the discharge gutter 17 of the elevator 13, and the inlet 20 is opened in the collision wall 19 provided at the abutting position of the discharge gutter 17. The thrower 23 is attached to the outside of the inlet 20, and the axial direction of the grain frying blades 24 of the thrower 23 is aligned with the supply conveyor 1.
The grain removal device in the circulating grain drying device is arranged in a horizontal direction crossing the axial direction of No. 8, and a switching valve 21 is installed between the inlet 20 and the starting end of the supply conveyor 18. It is something.

(Example) An example of the present invention will be described with reference to the drawings.
is a humidity control tank, which is a large hollow tank, and funnels 2 and 3 are formed at the bottom of the tank. The upper ends of the down-flow drying chambers 4 and 5 are connected to the lower ends of the funnels 2 and 3. Rotary valves 6 and 7 are attached to the lower ends of the downstream drying chambers 4 and 5. Reference numeral 8 denotes a receiving gutter attached to its lower part, which has a V-shape, and its upper end serves as a receiving plate 9 for the rotary valves 6 and 7.

The empty space between the downstream drying chambers 4 and 5 is the hot air supply chamber 1.
0, the vacant rooms outside the downstream drying chambers 4 and 5 become hot air exhaust chambers 11 and 11. A screw conveyor 12 is installed horizontally on the upper surface of the center of the receiving gutter 8. An elevator 13 is attached to the side of the fuselage. Elevator 13
A conveyor belt 16 is wound endlessly between an upper roll 14 and a lower roll 15. The grains discharged outside the machine by the screw conveyor 12 flow through a gutter (not shown) and flow into the lower part of the elevator 13. A discharge gutter 17 is attached to the upper part of the elevator 13 in the direction of discharging the bucket. A starting end of a supply conveyor 18 attached to the upper part of the humidity control tank 1 faces the lower end of the discharge gutter 17. Supply conveyor 18
The axial direction of the upper roll 14 is parallel to the axial direction of the upper roll 14. The collision wall 19 provided in the grain discharge direction of the discharge gutter 17 has a large opening to form an inlet 20. A switching valve 21 is installed between the inlet 20 and the starting end of the supply conveyor 18. Switching valve 21
is fixed by a shaft 22 provided at the lower end of the inlet 20, and when it stands up, it closes the inlet 20 and opens the supply conveyor 18, and when it falls down, it closes the supply conveyor 18 and opens the inlet 20. Open the blockage.
A thrower 23 is attached to the outside of the inlet 20. The thrower 23 has grain lifting blades 24 and is rotated by a motor 25. The thrower 23 frits the grains that flow in from the inlet 20, and returns the overflowed grains into the humidity control tank 1 through an overflow section 26. The axial direction of the grain lifting blade 24 is a horizontal direction that intersects with the axial direction of the supply conveyor 18.

(effect) Next, we will discuss the effect.

Since the present invention has the above-mentioned structure, when the raw unhulled rice is stretched into the lower end of the elevator 13, the loaded unhulled rice is scooped up by the conveyor belt 16 and ascends, and when the upper roll 14 at the upper part is rotated, it is It is powerfully thrown in the direction.

Therefore, the switching valve 21 is connected to the shaft 2 as shown in FIG.
If the switch valve 2 is left standing in the center, the switching valve 2
1 itself becomes a collision wall 19, and the grains that collided with the switching valve 21 are reflected and flowed down, and are supplied onto the starting end of the supply conveyor 18, and are carried by the supply conveyor 18 to the center of the humidity control tank 1 and fall. And funnel 2 and 3
It flows into each of the down-flow drying chambers 4 and 5, and is stopped by the rotary valves 6 and 7, and the water flows not only into the down-flow drying chambers 4 and 5, but also into the funnels 2 and 3 and into the humidity control tank 1. Filled with unhulled rice.

In this state, when the rotary valves 6 and 7 are rotated to allow the unhulled rice to flow down little by little, the partially dried unhulled rice is collected in the receiving gutter 8 and sent to the screw conveyor 1.
2, is sent out of the machine, flows down a gutter provided outside the machine, flows into the lower part of the elevator 13, is lifted up again by the conveyor belt 16, is supplied to the supply conveyor 18 from the discharge gutter 17, and is then processed. The unhulled rice is piled up on top of the wet tank 1, and the overloaded unhulled rice enters the down-flow drying chambers 4 and 5 again to be dried.

When drying is completed, when the switching valve 21 is tilted down as shown in FIG. 2, the inlet 20 of the collision wall 19 opens wide. Therefore, the unhulled rice that has been strongly thrown by the conveyor belt 16 flows into the inlet 20 as if thrown into the inlet 20, and the grains are thrown in as shown by the arrows in Fig. 2, so that they can be swallowed very easily. It flows into the thrower 23, and the clogging phenomenon is almost eliminated.

In addition, since the overflow part 26 is provided, the thrower 23 is further prevented from becoming clogged.

(Effects) Conventionally, a humidity control tank for controlling the humidity of grains was installed at the top, a down-flow drying chamber for drying the grains was installed at the bottom, and an elevator was installed on the side. In the case where a supply conveyor for transferring to the center of the wet tank is installed horizontally, the axial direction of the upper roll of the conveyor belt of the elevator is parallel to the axial direction of the supply conveyor, and the grains in the discharge gutter of the elevator are formed parallel to each other. The starting end of the supply conveyor is located at the discharge end position, an inlet is opened at the lower part of the discharge gutter, a thrower is attached to the lower part of the inlet, and the axial direction of the grain lifting blade of the thrower is aligned with the direction of the axis of the feed conveyor. The one parallel to the axial direction is described in Japanese Utility Model Application Publication No. 53-29964.

The problem with the known example is that the starting end of the supply conveyor is located at the grain discharge end position of the discharge gutter of the elevator, and the inlet is opened at the bottom of the discharge gutter.
A thrower is attached to the lower part of the inlet, and the axial direction of the grain frying blades of the thrower is parallel to the axial direction of the supply conveyor. Therefore, the grain will flow into the thrower by its own weight, but in the case of the thrower, since the thrower itself has almost no force to suck in the grain, there is a risk that the known structure will cause grain clogging.

However, in the present invention, the humidity control tank 1 for controlling the humidity of the grains is installed at the top, the down-flow drying chamber 4 for drying the grains is installed at the bottom, the elevator 13 is installed at the side, and the humidity control tank 1 is installed at the upper center of the humidity control tank 1. In this case, a supply conveyor 18 for transferring grains to the center of the humidity control tank 1 is installed horizontally, and the axial direction of the upper roll 14 of the conveyor belt 16 of the elevator 13 and the supply conveyor 18 are
The axial directions of the conveyor 18 are parallel to each other, the starting end of the supply conveyor 18 is located at the lower end of the discharge gutter 17 of the elevator 13, and the inlet 20 is opened in the collision wall 19 provided at the abutting position of the discharge gutter 17. The thrower 23 is attached to the outside of the inlet 20, and the axial direction of the grain frying blades 24 of the thrower 23 is aligned with the supply conveyor 1.
The grain removal device in the circulating grain drying device is arranged in a horizontal direction crossing the axial direction of No. 8, and a switching valve 21 is installed between the inlet 20 and the starting end of the supply conveyor 18. Therefore, when the switching valve 21 at the end of drying is tilted down as shown in FIG.
Because it flows in as if being thrown into the inflow port 20,
As the grains are thrown in as shown by the arrow in Figure 2,
It flows into the thrower 23 in a state where it can be easily swallowed, and the clogging phenomenon is almost eliminated.
