Description

Description: [Industrial field of application] The present invention relates to a water content detection device for detecting water content of a grain, and can be used in a grain dryer, a grain drying plant, and the like.

[Conventional technology]

Generally, a grain is supplied between the moisture detecting rolls which also serve as a pair of left and right electrodes, and the moisture is detected while crushing the grain. That is, the grain supply mechanism section is arranged above the left and right moisture detecting rolls for detecting the moisture content of the crushed grain while the grain is being crushed by pressing (actual exploitation 57
-61491).

By the way, when driving a pair of the moisture detection rolls and driving of the grain supply mechanism unit are linked from the shaft of the drive motor, the left and right moisture detection rolls and the grain supply mechanism unit are arranged in a vertical relationship. Drive motors must be installed away from these occupants. For example, the above-mentioned actual exploitation 57-61491
Drive motor at a position greatly separated laterally as shown in Fig. 1 and is linked with the shaft of the motor separately by chain interlocking, or the drive force of the drive motor via a reduction interlocking gear at the rear part of the moisture detection roll. (For example, the actual development of Sho 58-2
No. 8296) and the like, and in any case, it is necessary to provide the space occupied by the cylindrical drive motor itself in the moisture detection case.

[Problems to be Solved by the Invention]

Therefore, the water content detection device itself is bulky. The present invention is intended to reduce the size of a moisture detecting device including a drive motor, particularly by keeping the right and left width within a range that does not largely deviate from the left and right width of a pair of moisture detecting rolls.

[Means for Solving the Problems]

This invention is a pair of left and right moisture detection rolls 1 and 2 for detecting moisture while crushing and crushing grains, while feeding the grains to one side while feeding the moisture between the moisture detection rolls 1 and 2. And a motor 4 for interlocking the moisture detecting rolls 1 and 2 and the feeding mechanism with gears 9, 10 and 14 on the other side. A chute 18 for guiding the grain from the feeding mechanism between the pair of left and right moisture detecting rolls 1 and 2 is arranged so that the motor 4 is located substantially directly above one of the rolls and is inclined obliquely below the motor 4. The grain moisture detector is provided.

[Operation of the invention]

By driving the motor 4, a pair of left and right moisture detection rolls 1,
2, and the feeding mechanism is rotated, and the grain fed by the rotation of the feeding mechanism is guided between the moisture detection rolls 1 and 2 by the chute 18, and the moisture of the grain is detected while being crushed by these.

〔The invention's effect〕

Since the present invention is configured as described above, the motor 4 and the feeding mechanism are positioned on the upper side, and the moisture detection rolls 1 and 2 for receiving the grains fed from the feeding mechanism and detecting the moisture are lowered. By providing the chute 18 of the feeding mechanism diagonally below the motor 4, it is possible to smoothly maintain the supply of the grain to the moisture detection rolls 1 and 2 from the feeding process by the feeding mechanism of the motor 4, A guide chute 18 is disposed in an obliquely lower portion of the motor 4, that is, the chute can be disposed along a part of the outer periphery of the cylindrical motor 4, and the motor 4, the feeding mechanism, the moisture detection rolls 1, 2 and the like are provided. Can be accommodated in a small space as a whole, and the unit can be made compact to simplify the handling.

〔Example〕

 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, From the reduction gear 9 of the motor 4 to the gear 10 of the moisture detection roll 2
A series of gear mechanisms such as a gear mechanism that interlocks to rotate the other moisture detection roll 1 from the 10th shaft via gears 12 and 13, and a gear mechanism that further interlocks to rotate the three delivery roll shafts from the gear 10 to the gear 14. The interlocking mechanism of is installed.

On one side of the motor 4, a feeding mechanism including the feeding roll 3 and the guide plate 16 is located. Of these, feeding roll 3
A spiral groove 15 is formed on the outer peripheral surface of the feeding roller 3 so as to fit about one grain and can be transported along the axial direction. The guide plate 16 is provided in order 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 side end of the guide plate 16, and the chute is seen above between the pair of left and right moisture detecting rolls 1 and 2. The motor 4 is provided with an anti-shield cover 25.

A pair of left and right moisture detection rolls 1 and 2 are provided below the motor 4 and the feeding mechanism.
Gears 13 and 12 for rotating 1 and 2 are configured to set a rotation difference so as to crush the grains held between the rolls 1 and 2, and these both moisture detection rolls 1 and 2 have electrodes. In addition, the crushed grains pass between the rolls 1 and 2 to energize the measuring instrument body side to detect moisture.

These motor 4, feeding mechanism, detection rolls 1, 2 etc.
It can be covered with a cover 19 which is attached to and detached from 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 as electrodes is attached to one side of the mounting base 5 located inside the cover 19. . This printed circuit board 20 partitions the inside of the cover 19 with a partition wall 24, and includes the motor 4, the feeding mechanism, and the moisture detection roll.
It may be installed in a storage room that is hermetically shielded from the storage room such as 1, 2, etc.

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, and thus the above feeding mechanism. Let me guide you. Further, on the lower side, there is provided a discharge cylinder 23 which receives the grain overflowed from the transfer zone of the feeding mechanism and guides it back into the grain submersible machine 6.

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. The water is transferred to the side, and is fed out from the chute 18 onto the moisture detecting rolls 1 and 2, and the moisture is detected while being crushed between the moisture detecting 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 are
It falls down and is returned to the inside of the grain raising machine 6 from the discharge cylinder 23.

When removing the mounting base 5, the guide tube 21, and the discharge tube 23, the bolt 8 may be loosened.
