Description

[Detailed description of the invention] A downstream chamber B made of a perforated plate is connected to the lower part of the grain storage chamber A, and hot air from the hot air chamber C adjacent to one side of the downstream chamber is blown into the downstream chamber B to cool down the grains flowing down. After drying the grains, the moist folding screen passes through the exhaust chamber adjacent to the other side of the downstream chamber and is discharged to the outside of the machine by the suction fan F installed on the back of the machine facing the hot air chamber C, and then into the downstream chamber B. There is a gap M between the lower bottom and the machine wall.
The dryer drops the dried grains through a rotary valve R having be.

In this type of grain dryer, the grains that have been dried to a predetermined moisture level are taken out of the machine by switching the switching valve provided at the discharge port at the top of the grain frying machine. It is inevitable that dust, straw and grain will remain in the gap M between the machine wall and the machine wall.

Conventionally, there are machines in which the machine wall K is tilted toward the grain collecting room E, but the remaining grains are blocked by the rotary valve R and cannot be taken out, and there are also machines in which the machine wall K is pulled out of the machine. ,
Not only is the structure complicated, but the operation of removing and inserting the machine wall K requires considerable effort.

The purpose of the present invention is to use the existing suction fan F to clean the remaining grains without discharging the grains to the outside of the machine.

To explain the embodiment shown in the drawings, a suction fan F is provided on the back of the machine body facing the hot air chamber C, an opening/closing plate 1 is attached to the end of the exhaust chamber leading to the suction fan F, and the upper end of the rotating shaft 2 is connected to the outside of the machine. A handle 3 is fixed by protruding from the grain collecting chamber E, and a suction port 4 communicating with an upper suction fan F is provided in the grain collecting chamber E.

The handle 3 is connected by a spring to a stopper 5 attached to the machine body, and the handle 3 is rotated against the spring, and the rotation shaft 2 and the stopper 5 are rotated.
When the line connecting the handle 3 is crossed, the spring contracts and fixes the handle 3 in that position.

However, in the present invention, when the handle 3 provided outside the machine is placed in the position shown by the solid line in Figure 5 during grain drying, the opening/closing plate 1 is brought into close contact with the machine wall as shown by the one-dot chain line in Figure 3, and the exhaust chamber is closed. The end of the folding screen is opened and communicated with the suction fan F, and the folding screen containing moisture is sucked and discharged outside the machine.

Next, after drying the grains, turn the handle 3 by 90' and place it in the position shown by the imaginary line in FIG. , the suction force at the suction port 4 of the grain collection room E that communicates with the suction fan F above is increased.

Therefore, the suction force to the gap M between the rotary valve R in the upper part of the grain collecting room E and the machine wall facing the lower surface of the rotary valve R increases rapidly, so that the dust, straw waste, and grains remaining in the gap M are immediately sucked upward. The heavy grains sucked out by the fan F slide down into the grain collection chamber E, and light dust and straw waste are discharged outside the machine and do not remain.

In this way, according to the present invention, the suction fan F is installed on the back of the machine body facing the hot air chamber C, and the opening/closing plate 1 is installed at the end of the exhaust chamber leading to the suction fan F. The grain collection chamber E is equipped with a suction port 4 that leads to the suction fan F above, so when the grains are drying, the opening/closing plate 1 at the end of the exhaust chamber is opened to suck out the moist folding screen to the outside of the machine. After the drying is completed, the opening/closing plate 1 at the end of the exhaust chamber is closed, and the dust, straw, and grains remaining in the gap M above the grain collecting chamber are removed through the suction port 4 using the suction force of the suction fan F. Light dust and straw waste are sucked up and discharged outside the machine, and heavy grains that cannot be sucked up are allowed to slide into the grain collection chamber E, thereby achieving the effect of cleaning the gap M without discharging grains outside the machine. have
