DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In the four corners of the outer periphery of the die-cast mounting base 5, bolt holes 8 for mounting the mounting base 5 to the side plate 7 of the grain raising machine 6 of the grain dryer are provided, and in the mounting base 5, Motor 4
From the reduction gear 9 of the above to the gear 10 of the moisture detection roll 2,
A gear mechanism interlockingly configured to rotate the other moisture detection roll 1 from the shaft of the gear 10 through gears 12 and 13, and a gear mechanism interlockingly configured to further rotate the three supply roll axes through the gear 10 to gear 14. It is equipped with a series of interlocking mechanisms.

On one side of the motor 4, a feeding mechanism including the feeding roll 3 and the guide plate 16 is located. Of these, a spiral groove 15 is formed on the outer peripheral surface of the feeding roll 3 so that about one grain can be fitted and transferred along the axial direction. The guide plate 16 is provided between the feeding roll 3 to receive and guide the grain, and the upper end of the guide plate 16 is rotatably mounted around the pin 17. Reference numeral 18 denotes a chute provided at one end of the guide plate 16 and is seen upward between the pair of left and right moisture detecting rolls 1. The motor 4 is provided with an anti-shield cover 25.

A pair of left and right moisture detecting rolls 1 and 2 are provided below the motor 4 and the feeding mechanism, and gears 13 and 12 for rotating the moisture detecting rolls 1 and 2 are provided.
Is configured to crush the grains held between the rolls 1 and 2 by crushing, and both of these moisture detecting rolls 1 and 2 also serve as electrodes, and the crushed grains are between the rolls 1 and 2. By passing through, electricity is supplied to the measuring instrument main body side to detect moisture.

The motor 4, the feeding mechanism, the detection rolls 1, 2 and the like can be covered with a cover 19 which is detachably mounted on the base 5. A printed circuit board 20 for energizing the motor 4 and for printing the electrode circuits of the moisture detection rolls 1 and 2, which are electrodes, is attached to one side of the mounting base 5 located inside the cover 19. . This printed circuit board 20
Is provided in a storage chamber (a) which is partitioned airtight from the storage chambers of the motor 4, the feeding mechanism, the moisture detection rolls 1, 2 and the like by partitioning the inside of the cover 19 with a partition wall 24.

A guide cylinder 21 is attached to the upper side of the mounting base 5, and the upper end of the guide cylinder 21 communicates with the opening 22 of the side plate 7 of the grain raising machine 6 to receive a part of the falling grains during grain raising, Guide it on the feeding mechanism. Further, on the lower side, a discharge cylinder 2 that receives the grain overflowed from the transfer zone of the feeding mechanism and guides it back into the sublimation machine 6
3 is provided. The grain guided from the opening 22 into the guide cylinder 21 is received between the feeding roll 3 and the guide plate 16, and the grain fitted into the spiral groove 15 by the rotation of the feeding roll 3 has a tip end. It is transferred to the side and shoots one grain at a time
The water is fed from the water detection rolls 1 and 2 onto the water detection rolls 1, and the water is detected while being crushed between the water detection rolls 1 and 2. The crushed grains that have passed between the moisture detection rolls 1 and 2 and the grains that have flowed over the feeding roll 3 fall downward and are returned to the inside of the grain raising machine 6 from the discharge cylinder 23.

When the cover 19 is removed, the motor 4, the feeding mechanism, the moisture detection rolls 1 and 2, and the printed circuit board 20 arranged on the mounting base 5 are exposed to allow various maintenance. Furthermore, when removing the mounting base 5, the guide cylinder 21, and the discharge cylinder 23, the bolt 8 may be loosened.

[0010]

According to the present invention, the mounting base 5 is provided with the motor 4, the moisture detection rolls 1 and 2 interlocked with the motor 4, the feeding mechanism, and the like, and is detachable so as to cover them. A cover 19 is provided, the interior of the cover 19 is partitioned by a partition wall 24, and the printed circuit board 20 of the electrode circuit is provided in the non-existing side accommodation chamber (a) of the moisture detection rolls 1 and 2.
Because are arranged in parallel form to 4, dust such induced me grain coupled with between moisture detection rolls 1,2 the feeding mechanism portion is blocked by the partition wall 24, easily the accommodation Since it is difficult to move to the chamber (a) side, the printed circuit board 20 can be prevented from being contaminated by dust, and no malfunction occurs. Of course, a single cover 19
The motor 4 mounted on the mounting base 5 by removing the
The detection rolls 1 and 2 and the printed circuit board 20 are exposed
The rolls 1, 2 and other mechanical mechanisms and electrode circuits
It is easy to perform maintenance for both. in addition,
Is the printed circuit board 20 arranged in parallel with the partition wall 24?
, Left of the non-existing side storage chamber (a)
The right width can be suppressed and the size can be reduced.
