Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grain drying device for drying grains using drying air.

[Prior Art] In order to dry grains, a circulation type grain drying device is used, which circulates and flows the grains in a grain tank while supplying drying air to dry the grains.

In this circulation type grain drying device, for example, grains loaded from an opening/closing hopper on the side are flowed down to the lower part of the machine body by a loading sink plate, and are further passed through a lower screen arranged in the longitudinal direction of the machine body. It is transported to one side of the lower part of the fuselage by the Yu-conveyor. and,
The grain is lifted and conveyed to the top of the machine by a grain lifting machine connected to the screw conveyor and installed outside the machine. The transported grains are transported to the upper central part of the machine body by an upper screw conveyor and stored in a storage chamber in the machine body by a rotary equalizer. Then, the grains are further dried by gravity in the drying section, and then circulated again by each screw conveyor, grain lifting machine, etc., and the above-mentioned steps are repeated until the desired moisture content is reached.

However, in this type of circulating grain drying device, the grain loading operation requires opening the loading hopper, manually lifting the combine bag, and loading the grains inside the bag into the drying device. For this reason, it is extremely inefficient especially when it comes to processing a large amount of grain quickly and reliably, and it also places an excessive burden on workers.

[Problems to be Solved by the Invention] The present invention takes the above facts into account and aims to provide a grain drying device that can quickly, reliably, and efficiently pack a large amount of grain.

[Means for Solving the Problems] The grain drying device according to the present invention includes an opening/closing hopper that is pivotally supported to open and close the grain loading port formed on the side wall of the machine body, and a pivoting support of the opening/closing hopper. a hook provided nearby and capable of locking a grain bag; and a hook attached near the grain loading port of the machine body, capable of winding up a long body having one end connected to the opening/closing hopper;
and a winding device that opens and closes the opening/closing hopper in a state in which the grain bag is locked to the hook by winding up or unwinding the elongated body.

[Function] At the time of tensioning, the elongated body is unwound by the winding device, the opening/closing hopper is opened, and the grain bag is further secured to the hook of the opening/closing hopper. Therefore, even if the hopper is tilted, the hook prevents the grain bag from falling off, so the opening/closing hopper can be opened to a position where the grain bag can be easily loaded.

Next, when the long body is wound up by a winding device,
The opening/closing hopper tilts to hold the grain bag and push the grain inside the machine.

A motor, hydraulic cylinder, etc. can be used as a drive source for the winding device, which reduces the labor required to lift the grain bag.

[Example] Fig. 1 shows a sectional view of a grain drying device 10 according to the present invention, and Fig. 2 shows a side view.

The body 12 is the outer frame of the grain drying device 10, and is shaped like a box with vertically high heights.

The upper inner cavity of the fuselage 12 serves as a grain tank 14.
A drying section 16 is provided at the bottom of the body 12. A pouring sink plate 18 is arranged below the drying section 16 and tapered downward toward the center between the left and right bodies 12. The machine body 12 side of the filling sink plate 18 communicates with the grain filling port 12A. For this reason, the grains that have passed through the drying section 16 and the loading port 12
The grains poured from A are accumulated near the center of the machine body 12 by the pouring sink plate 18.

A pair of lower screw conveyors 20 for conveying grains are disposed at the lower end of the pouring sink plate 18. The lower screw conveyor 20 is arranged along the longitudinal direction of the machine body 12, and the spiral blades on the outer periphery send out the grains that enter between these blades to the left in FIG. 2.

A downwardly inclined conveyance guide plate 22 is connected to the terminal end of the lower screw conveyor 20 in the grain conveyance direction, and is adapted to cause the grains to flow down. Further, the lower end of the conveyance guide plate 22 is adapted to supply grains into a bucket of a bucket conveyor 24 erected outside the machine body 12 .

In this bucket conveyor 24, grain conveyor buckets are attached to the endless conveyor at regular intervals, and the grains sent from the lower screw conveyor 20 via the conveyance guide plate 22 are transferred to the grain drying device 10. It can be lifted and transported to the top. Therefore, the grains flowing down the conveyance guide plate 22 are lifted and conveyed to the top of the grain drying device 10 via the conveyance bucket.

One end of the upper screw conveyor 26 corresponds to the upper end of the bucket conveyor 24, and is adapted to receive the lifted and conveyed grains. The other end of the upper screw conveyor 26 extends to the center in the longitudinal direction of the grain drying device 10, and a rotary equalizer 28 whose axis is vertical is arranged directly below the other end of the upper screw conveyor 26. ing. Therefore, the grains conveyed to the upper center of the grain drying device 10 by the upper screw conveyor 26 fall onto the rotary equalizer 28 .
The grain tank 1 in the grain drying device 10 is rotated by centrifugal force.
It will be evenly distributed within 4.

An air guide communication passage 30 is formed in the vertical direction on the front of the body, and a burner 32 for generating drying air is disposed at the lower part of this air guide communication passage 30. An exhaust air passage 34 is formed in the vertical direction on the rear side of the body, and a suction exhaust fan 38 for exhausting air is disposed near the exhaust port 36 of this exhaust air passage 34. Therefore, this suction/exhaust fan 38 sucks the drying air from the burner 32, sends it into the drying section 16 through the air guide passage 30, and discharges it to the outside of the machine body 12 via the air exhaust passage 34. There is.

A shutter drum 39 is arranged below the drying section 16. The shutter drum 39 has a hollow cylindrical shape with a horizontal axis, and a slit-like notch with a predetermined width along the axial direction is formed in a part of the outer periphery. The shutter drum 39 rotates about its axis and discharges the grains that have flowed down the drying section 16 to a position where the lower screw conveyor is disposed.

Now, hoppers 40 are arranged on both sides of the body 12, and the lower end portions are pivotally supported on the body 12 so that the loading port 12A can be opened and closed. A hook 4 for locking the combine bag 41 is located near the shaft portion of the hopper 40.
2 protrudes and can be locked into locking holes formed at both ends of the combine bag 41 filled with grains. Further, a wire locking fitting 44 is fixed to the tip of the hopper 40.

A winder 46 with a built-in motor is disposed on the side of the body above the hopper 40, and is capable of winding up the wire 48. The other end of the wire 48 is locked by the wire locking fitting 44 . The motor and winder 46 therefore constitute lifting means, and by winding and unwinding the wire 48 the hopper 40
It can be opened and closed.

Next, the operation of the grain drying device 10 having the above configuration will be explained.

The circulation system devices (lower screw conveyor 20, bucket conveyor 24, upper screw conveyor 26, and rotary equalizer 28) of the grain drying device 10 are driven to load the grains. Furthermore, when the motor for the winder is driven to reverse the winder 46 and rewind the wire 48, the hopper 40 is opened. (The state shown in Figure 1). Here, the combine bag 41 packed with grains is hung on the hook 42 and mounted and locked on the hopper 40. In order to facilitate loading of the combine bag 41, it is preferable to open the hopper 40 to about 150 degrees as shown in FIG.

If the wire 48 is wound up by the motor drive, the hopper 40 is lifted and tilted by the wire 48. When the hopper 40 is lifted up and tilted above the charging port 12A, the winder 46 is stopped, and when the combine bag 41 is opened, the packed grains are pulled into the grain drying device 10 by their own weight. The combine bag 41 may be opened before the hopper 40 is lifted.

The loaded grains are guided by the loading sink plate 18 and reach approximately the lower center of the machine body 12 (lower screw conveyor arrangement position).

Then, it is conveyed to the bucket conveyor 24 side by the lower screw conveyor 20. Since a downwardly inclined conveyance guide plate 22 is connected and communicated with the terminal end in the conveyance direction, the grains are successively transferred to the conveyance guide plate 22.
along the bucket conveyor 24. Therefore, the grains flowing down the conveyance guide plate 22 are separated and lifted by the bucket of the rotating bucket conveyor 24.

The grains lifted and conveyed above the machine body 12 by the bucket conveyor 24 are sent to the upper central part of the machine body 12 by the upper screw conveyor 26, and are transferred to the machine internal grain tank 14 by the rotary equalizer 28. stored in

On the other hand, when all the grains in the combine bag 41 are filled, the empty combine bag 41 is removed from the hook 42. If necessary, the winder 46 is driven again to load and lock the next combine bag 41 and fill it with the required amount of grain.

When the tensioning is completed, the wire 48 is wound up to lift the hopper 40 by the maximum amount, and the tensioning opening 12A is closed.

Furthermore, the shutter drum 39 is driven here to feed out the grains, and the burner 32 connected to the machine body 12 is
When igniting and driving the suction exhaust fan 38,
Drying air is sent into the drying section 16 through the air guide passage 30. After the drying air sent to the drying section 16 absorbs the moisture of the grains, it is sucked by the suction/exhaust fan 38 and is discharged to the outside of the machine body 12 through the exhaust communication passage 34.

The grains that have passed through the drying section 16 are sent to the shatter drum 3.
9, pouring sink plate 18, lower screw conveyor 2
0, the grains are lifted to the upper part of the machine body via the bucket conveyor 24, and after the above-mentioned circulation action is repeated in the machine body 12 as necessary until a desired moisture content is reached, the grains are taken out from a grain outlet (not shown).

Note that the hoppers placed on both sides of the fuselage 12 are
It may be arranged only on one side, or it may be provided on both sides only when it is particularly necessary.

Further, when the winder 46 is used, the wire 48 is not limited to lifting the center portion in the left-right direction of the hopper 40, but may also be used at the end portion.

[Effects of the Invention] Since the present invention has the above-mentioned configuration, it has an excellent effect that a large amount of grains can be packed at once easily and quickly with little effort.
