Abstract

Dried grains were removed from a dryer by applying air to a certain pressure within a closed drying chamber and then opening outlets all of once for burst-discharge. Thus, grains were poured into a hopper (2), transported to a drying chamber (5) by air blowing through a flow tube (4), and air-dried. After closing clamber (5) by shutting a ventilator (7), a preset air pressure was built as within chamber (5) by blowing air in through a air holes (8) (15) (15') using an air blowes (17). The dried grains were removed completely from (5) by letting out compressed-air all at once through outlets (6,6',6") with the guide of porous steel plate (13).

The present invention relates to a method of introducing grain into a grain dryer and quickly discharging dried grains without using manpower or other machinery.

Conventionally, the input or discharge of grain into the dryer was mainly by manpower, and in the case of a large quantity, separate heavy equipment was used. However, since heavy equipment is very expensive, all of them were by human resources in rural areas of Korea. However, the input and output by these human resources were weak and the work efficiency was extremely low.

The present invention is to enable the rapid input and discharge of grain by the force of the wind and the air pressure, regardless of the low manpower or expensive heavy equipment.

That is, in the present invention, grains are introduced into the hopper 2 installed lower than the dryer 1 so that the grains are introduced into the dryer 1 along the transfer pipe 4 by the blowing of the blower 3, and then in the drying chamber 5. When the grain is dried, close the drying vent (7) to close the drying chamber (5) and continue to blow through the guide holes (8) (15) (15 ') to form a constant air pressure in the drying chamber (5) and then the outlet (6) By opening at a time, the grain is discharged out of the drying chamber (5) by the jet of air pressure and the continuous blowing of the guide hole (8) toward the outlet (6).

At this time, a triangular guide cylinder 9 is disposed between the discharge opening 6 and the discharge opening 6 ', and between the left and right side walls 10, 10' and the discharge opening 6, 6 " Each of the triangular guide tube (11) (11 ') is installed so that the grain is caught on the wall between the axle (6) to prevent incomplete discharge.

The characteristics of the present invention in the grain input method may be that the hopper 2 is installed lower than the dryer 1 and the drying effect can be obtained together with the transfer by the grain transfer by the wind.

That is, since the height of the dryer 1 requires a lot of force at the time of grain input, the position of the hopper 2 is lowered to make grain input easier, and the conveyance of the dryer 1 by the blower of the blower 3 uses a conveyor or the like. Not only is it more economical than the transfer by wind, but the effect of drying can be obtained at the same time.

In addition, the method of discharging grain is a new method that has never existed before. Drilling a guide hole for blowing dry wind toward the discharge port causes the dry wind to push the grain toward the discharge port. It is to make it easy and quick to discharge.

The present invention will be described in detail with reference to the accompanying drawings and embodiments as follows.

EXAMPLE

The grain dryer for carrying out the present invention has a drying chamber 5 and a perforated iron plate 13 having a width of the discharge opening 6 and a drying chamber 5 and a drying chamber 5. It is installed between the ventilation chambers 14 and coincides with the outlet 6, and a triangular guide cylinder 9 is provided between the perforated iron plate 13 and the perforated iron plate 13 ', and the left and right side walls 10, 10' and the outlet ( 6) (6 ') between the triangular guide tube (11) (11') is installed on the perforated sheet 13, the front guide hole for guiding the dry goods toward the outlet (6) as shown in the "third" 8) and a plurality of inclined guide holes 15 and 15 'slightly open to the left and right to guide the slopes of the left and right triangular guide cylinders 9 and the right triangular guide cylinders 11 and 11', and the drying chamber 5 The other side of the grain transfer pipe (4) connected to the center of the ceiling (16) of the opening and closing the hopper (2) and the blower (3) to address the position of the hopper (2) lower than the dryer (1).

Reference numeral 17 denotes a blower 18, a blower tube 19, and a leg of the dryer 1.

The present invention is carried out by the grain dryer (1) as described above is a method for inputting and discharging grains as follows.

When the grains are put into the hopper 2 and blown by the blower 3, the grains are introduced into the drying chamber 5 along the transfer pipe 4, and the added grains are evenly accumulated in the drying chamber due to its own weight and downwardly blown wind.

When the input of grain is completed, the blower 3 stops.

When the grains introduced into the drying chamber 5 are completed by the blowing of the blower 17 through the ventilation chamber 14, the ventilation opening 7 is closed (the discharge opening is already closed during the drying operation), and the drying chamber 5 is closed and the blower is closed. If the air blown by (17) is continued, the air continues to flow into the drying chamber 5 through the guide holes 8, 15 and 15 ', so that a considerable air pressure is formed in the drying chamber 5.

If the air pressure is uniformly formed in the drying chamber 5 (at this time, the air pressure varies depending on the type and amount of grain), the outlet 6 is opened at a time while continuing to blow.

Due to the air pressure formed in the drying chamber 5, the air is rapidly ejected to the outlet 6, and at the same time, the dry air blown from the guide hole 8 drilled toward the outlet 6 is pushed to the outlet 6 so that all the grains are discharged out. Will be.

At this time, since the triangular guide (9) and the triangular guide (11) guides all the grains on the perforated steel plate (13), the discharge of the grains is completely completed without the remaining amount in the drying chamber (5).

Therefore, the present invention can reduce the manpower and perform a quick and efficient work by quickly and easily input and discharge the grains by using the blowing air and the air pressure in the drying chamber without using expensive heavy equipment or inefficient manpower It is.

Claims (1)

Grain is fed into the dryer 1 by blowing the blower 3 through the hopper 2 and the transfer pipe 40 installed lower than the dryer 1, and the air pressure is formed by closing the drying chamber 5 and porosity. The grain conveying method of the dryer for discharging grain out of the drying chamber (5) by the wind blown toward the outlet (6) through the guide hole (8) of the iron plate (13).
