The grain is circulated by a circulation mechanism such as the grain elevator 8 in front of the machine wall. An opening 9 is formed on one side wall of the grain submersible machine 8, and the moisture detecting device 10 can be removably attached thereto.

The moisture detecting device 10 includes a box body 10 'formed by front and rear and left and right plate bodies 11 to 14, and two supporting metals 1 provided inside the box body 10' with a predetermined space therebetween.
5, 16 and a feeding mechanism 2 ′ composed of a pair of supply rolls 2 and 2, a pair of moisture detection rolls 3 and 3, supply rolls 2 and 2.
31, a detection roll 3, 3, etc., which should be rotationally interlocked, a transmission gear group for transmitting the rotation of the motor 31, a cleaning roll 3
0, a supply gutter 1'provided to connect the opening 9 and the supply port 1 of the box 10 ', and the like.

Regarding the feeding mechanism 2 ', the supply rolls 2,
2 has a spiral groove formed on the outer periphery thereof,
Located between 5 and 16 is metal 15, and auxiliary metal 19
Support the shafts 17 and 18 of the supply rolls 2 and 2. These are rotatably interlocked with each other and receive one grain, and one of the grains accumulated on the starting end side can be axially transported by the rotation of the transfer rolls 2 and 2. Reference numeral 21 is a grain receiving plate that is provided below the supply port 1 and receives and stores the grains. The supporting metals 15 and 16 are front plates 12
And the rear plate 11 are arranged so as to be in a posture perpendicular to the side wall of the grain-raising machine 8.

Below the transfer end portions of the supply rolls 2 and 2, a pair of left and right moisture detection rolls 3 and 3 can be seen. These are configured such that the peripheral speeds are set to be different from each other by reverse rotation, and the grains are crushed and crushed while the electrical resistance value and the like of the grains are converted into moisture. The rotation of the motor 31 is caused by the supply rolls 2 and 2 and the moisture detection roll 3 through the transmission gear group.
3 is transmitted to the third and the like. The rotation of the motor shaft 32 is transmitted to the large diameter gear 25, and the detection roll shaft 23 supporting the gear 25 is rotationally interlocked. Gear 2 provided on this shaft 23
A gear 27 is provided on the other detection roll shaft 24 so as to have a different number of teeth from the gear No. 6 and mesh with the gear 26.

The large-diameter gear 25 is meshed with the small-diameter gear portion of the two-stage gear 22 provided on the supply roll shaft 18, and the large-diameter gear portion integral with this gear portion is provided on the other supply roll shaft 17. Meshes with a number of gears 20. Reference numeral 29 denotes a shaft 28 of the cleaning roll 30 so as to mesh with the gear 25 having the large diameter.
It is provided in. The gear group 20, 22, 2
5, 29 and 32 are accommodated in the space between the rear plate 11 and the support metal 15.

Reference numeral 4 denotes a reducing port provided on the front plate 12, which is configured to communicate with an opening 9'on the side of the grain raising machine 8 and which feeds the grain supplied from the supply port 1 to the grain receiving plate of the supply roll 2. Grains other than those received in 21 are received and returned by the guide gutter 33 directly below. Reference numeral 34 is a discharge gutter having a U-shaped cross section, which is provided under the cleaning roll. The discharge gutter 34 has a discharge passage formed in a branched shape on the left and right sides, and a switching valve 35 is arranged at the top of the branch, and a crushed grain discharged from the detection rolls 3, 3 is switched by switching a lever 36 of the switching valve 35. This is a configuration in which it can be selectively discharged to the opening 9 ″ side passage a of the grain raising machine 8 or the outside discharge side passage b.

The operation of the above example will be described. The motor 31 of the water content detection device 10 is rotationally driven by a measurement command signal from the operation box 6, and the supply rolls 2 and 2, the water content detection rolls 3 and 3, and the cleaning roll 3 through the transmission gear group.
0 is linked with rotation. Grain is stretched from the grain raiser 8 to a storage chamber above the dryer 5, and is dried by receiving hot air generated from the burner 7 while flowing down the drying chamber from the storage chamber.
A part of the grains transferred to the upper part by the grain-raising machine 8 is supplied from the opening 9 through the supply port 1 into the moisture detecting device 10 being driven. This grain is received by the grain receiving plate 21 and accumulated therein, and a predetermined grain is engaged with the spiral groove and fed by this, and held between the spiral grooves of the pair of supply rolls 2 and 2.
Along with the rotation, it is transferred in the axial direction. Supply roll 2,
Grains falling from the transfer end of No. 2 are water detection rolls 3, 3
The water content is detected while falling and crushing by pressing between the rolls 3 and 3.

The grains crushed by the pressing force are removed by the brush action of the rotating cleaning roller 30 and fall down.
Depending on the operation position of the switching valve 35, it will be discharged to a predetermined position via the passage a or b. The supply roll 2,
2 Of the grains supplied to the starting end side, all of the grains accumulated on the grain receiving plate 21 or the excess grains are returned to the inside of the grain raising machine 8 through the opening 9 ′ by the guide gutter 33.

In the above description, during the grain drying operation, the vibration is transmitted to the side wall of the grain raiser 8 due to the vibration generated from each operating part, but the support metals 15 and 16 in the moisture detecting device 10 are attached to the side wall of the grain raiser 8. On the other hand, since it is arranged in a vertical posture, it is difficult for the vibration to be directly transmitted to the supply rolls 2 and 2 and the accuracy of feeding one grain is not impaired.
