Problems to be Solved by the Invention By the way, when the above-mentioned known grain dryer is used to sequentially dry different types of grains or seed grains, different types of grains and seed grains are mixed with each other. For the purpose of preventing the above, it is necessary to remove grains, straws, foreign substances, etc. hung on the ventilation surfaces of the hot air chamber and the exhaust chamber.

However, in this type of conventional grain dryer, the hot air chamber and the exhaust air chamber are both fixed and not removable, which makes it difficult to clean the hot air chamber and the exhaust air chamber. Alternatively, there arises a problem that different kinds of seed grains are mixed.

Means for Solving Problems The present invention solves the above problems, and the contents thereof will be described below with reference to FIGS. 1 to 5 corresponding to the embodiments. That is, the dryer main body 101 is formed in a horizontally long rectangular tube shape that is long in the front-rear direction. A hot air blowing chamber 102 and a dust exhausting chamber 103 are provided symmetrically on the left and right sides of the dryer main body 101 in a laterally long direction. Between the hot-air blowing chamber 102 and the dust-exhaust chamber 103, a hot-air slanting mountain-shaped partition body 106 and a waste-air-driving slanting mountain-shaped partition body 107 are alternately arranged side by side in a direction orthogonal to the lateral direction. To do.

In the lower part of the hot-air drainboard partition 106 and the exhaust-air drainboard partition 107, the inner wall 104 of the hot-air blowing chamber 102 and the inlet / outlet windows 108, 109 respectively opened in the inner wall 105 of the dust-blasting chamber 103 form an integrated housing. The formed ventilation drying case 110 is inserted freely in and out. The ventilation drying casing 110 has a hot-air slats 111 whose upper surface open side is covered with a chevron partition 106 for hot-air slats.
And the exhaust air drainboard 113 whose open side is covered with the mountain-shaped partition 107 for the exhaust air drainboard, between the two snowboards 111, 113.
The ventilation drying housings 110 in the shape of a box, which are alternately arranged so as to be respectively formed, are inserted in and out freely along the direction orthogonal to the laterally long direction. The left and right side walls of the ventilation drying case 110 connect the hot air blower 111 and the hot air blower chamber 102 to each other.
117, and an air exhaust window 118 that connects the exhaust air drainboard 113 and the dust exhaust air chamber 103 is formed.

Action Now, as shown in FIG. 1, the cover plate 121 of the hot air blowing chamber 102
And the cover plate 123 of the dust exhaust chamber 103 are removed, and then the hot air blow chamber 10
By using the inlet / outlet windows 108 and 109 opened on the inner wall 104 of the second part or the inner wall 105 of the dust exhaust chamber 103, respectively, the ventilation drying casing 110 having a short length and formed into a casing can be inserted. By the way, the upper open side of the plurality of hot-air slates 111 arranged vertically inside the ventilation drying housing 110 is covered with the chevron partition 106 for the hot-air sludge at the same time, and the upper open side of the exhausted slats 113 is also discharged. It is in a state of being covered in conformity with the mountain-shaped partition body 107 for the wind-shaped saw board. Therefore, the cover plates 121 and 123 are used to form the hot air blowing chamber 102 and the dust blowing chamber 103.
If the opening is closed, dry hot air is supplied from the hot air blowing chamber 102 into the hot air drainboard 111 through the air blowing window 117, then traverses the drying passage 115 and enters the exhaust air drainboard 113, and exhaust air from the air exhaust window 118. It is possible to carry out a distribution operation in which air is exhausted to the chamber 103. Therefore, under the conditions as described above, the seed grain as the dried grain is treated with the hot-air drainboard 111 and the exhaust-air drainboard 113.
Is supplied to the inside of the dryer main body 101 so as to be buried therein. Then, when a predetermined amount of seed grain is filled in the dryer main body 101, the supply is stopped, dry hot air is generated in the hot air blowing chamber 102, and at the same time, the dust exhaust chamber 103 is brought to a negative pressure state. If so, the generated dry hot air enters the hot air slat 111 through the blast window 117 from the hot blast chamber 102 due to the negative pressure inside the dust blast chamber 103, and then exits the hot air slat 111 to the drying passage.
After traversing 115, it enters the exhaust air drainboard 113, is further sucked into the dust exhaust air chamber 103 from the air exhaust window 118, and then is exhausted to the outside of the machine in a concentrated manner to perform a distribution action.

Therefore, the seed grain is exposed to the hot dry air flowing while flowing down the drying passage 115 many times, is finished and dried to a predetermined water content, and is discharged out of the machine.

By the way, when the seed grain drying operation is completed as described above, the previous seed grains, straws, or foreign substances are attached to the ventilation surfaces 112, 114 of the hot air drainboard 111 and the exhaust air drainboard 113. Repeated seed drying results in the previous seed grain being mixed with new heterogeneous grains. In such a case, the cover plate 121 of the hot air blowing chamber 102 and the cover plate 123 of the dust exhaust chamber 103 are removed, and then the ventilation drying housing 110 is removed.
To the right side or left side of the dryer main body 101 and pull out to the outside through the inlet / outlet windows 108 and 109 to quickly clean and remove seed grains, straws, foreign substances and the like adhering to the hot air drainboard 111 and the exhaust air drainboard 113. It is possible to easily inspect and clean the inside of the dryer main body 101 while saving labor.

As described above, when the inspection and cleaning of the inside of the ventilation drying housing 110 and the dryer main body 101 are completed, the ventilation drying housing 110 is inserted into the dryer main body 101 through the access windows 108 and 109, and the hot air blowing chamber 102 and After closing the opening of the dust exhaust chamber 103 with the lid plates 121 and 123, a new different type of seed grain is dried into the dryer body 101.
By filling the inside and drying it, different seed grains can be dried without being mixed.
