Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moisture detecting device for grains, which can be used in a grain dryer for drying grains.

[0002]

2. Description of the Related Art As disclosed in Japanese Unexamined Patent Publication No. 56-94251, a structure is known in which moisture is measured while sequentially supplying one grain.

[0003]

However, in such a structure, since the feeding supply unit is entirely arranged in the moisture detecting case, the grain flow-down passage formed in the dryer wall is directed toward the feeding supply unit. A guide chute is provided as a guide, and the guide chute is temporarily received by the guide chute and the entire amount thereof is transferred to the feeding supply unit.

Therefore, it is necessary to provide both a space for receiving a large number of grains and a single grain conveying section for engaging and transferring one grain from the space in the moisture detection case. You have to expand your inner space.

[0005]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned drawbacks, in which a grain-shaped water intake case is installed by opening a grain intake port on the side wall of the grain flow passage. ,
In the moisture detection case, a pair of left and right supply rolls 17 and 17 for receiving and feeding the grains flowing down the flow passage, and left and right for detecting moisture while receiving and crushing the supplied grains. A pair of electrode rolls 20, 21, supply rolls 17,
Motor 2 for driving and rotating 17 and electrode rolls 20 and 21.
4 and a water content detecting device for a grain provided with a transmission gear and the like, the supply rolls 17, 17 have a multi-grain receiving part capable of receiving a plurality of grains by partially projecting into the grain flow-down passage. A grain transporting unit provided above the electrode rolls 20 and 21 in the moisture detecting case and configured to engage and guide one grain while being interlockingly rotated, and to transport the grain. This is the structure of the moisture detector.

[0006]

The pair of left and right supply rolls 17, 17 for feeding the grain can project a part of the grain into the grain flow passage to receive a large number of grains. One of the many particles is engaged and fed into the moisture detection case while being fed into the moisture detection electrode rolls 20 and 21.
It reaches the upper side and is supplied between the rolls 20 and 21.

Therefore, the supply rolls 17, 17 for feeding one grain are provided between the grain flow-down passage and the moisture detecting case, and separate members such as a guide chute are required. Instead, it is sufficient to secure a space for occupying the conveying unit that feeds while one particle is engaged in the moisture detection case, and the case can be made compact.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 is a machine frame of a grain dryer, and the inside is a well-known configuration including a grain tank 2, a drying chamber and the like. 3 is an elevator and 4 is a burner. In the front part of the grain tank 2, a box-shaped moisture detector 5 or an operation box 6 is arranged.

The moisture detecting device 5 includes front and rear side plates 7, 8,
Bearing members 13 and 14 are provided in a moisture detection case formed by the upper and lower side plates 9 and 10 and the left and right side plates 11 and 12 so as to be partitioned into three spaces in a side view. Then, a pair of grain supply roll shafts 15 and 16 are axially supported by penetrating these bearing members 13 and 14, and supply rolls 17 and 17 having a spiral groove formed on one end side thereof are provided on the upper part of the case. still,
The leading ends of these supply rolls 17, 17 are configured such that a part of the supply rolls 17 project from the openings of the grain tank 2 and the front side plate 7 into the grain tank 2 and flow down the grains. That is, a part projecting into the tank 2 is used as a multi-grain receiving part, and the multi-grain receiving part is extended into the moisture detection case and a part of the grain is engaged with the multi-grain receiving part and transferred while being fed out. It is used as a single grain transport unit.

Electrode roll shafts 18 and 19 are provided below the supply roll shafts 15 and 16 in parallel with each other in the same manner as the roll shafts.
It is supported by 3,14. These electrode roll shafts 18,
19 An electrode roll 2 having an uneven surface on one end side
0 and 21 are provided. A cleaning roll shaft 23 having a brush-like cleaning roll 22 fixed below the electrode roll shafts 18 and 19
Are supported by the bearing members 13 and 14.

An interlocking gear group is arranged in the space between the bearing member 14 and the rear side plate 8. That is, the motor 24 is provided to project the main body toward the front side of the bearing member 14, and the drive shaft 25 of the motor 24 is projected toward the space portion side. Similarly, the gear 26 at the end of the shaft 25 disposed in the space is meshed with the two-stage gear 27 provided at the end of the electrode roll shaft 19. The small-diameter gear portion of the two-stage gear 27 is meshed with the gear 28 at the end of the electrode roll shaft 18 on the other side with which it meshes. Also, the above 2
The large diameter portion of the stepped gear 27 is the gear 2 of the one supply roll shaft 15.
9 and the gear 29 engages with the other supply roll shaft 16
The gear 30 of is interlocked.

Thus, the transmission gear groups 26 to 30 are centrally arranged in the space inside the rear plate 8 and the drive motor 2 is provided.
No. 4 can be arranged in a non-buffering position in the middle part of the shaft group, and there is an effect that the whole can be made compact and compact. Reference numeral 31 is a supply adjusting plate which forms the edges of the supply rolls 17 at the outer peripheral edges of the supply rolls 17, at an appropriate distance from each other. That is, the position is changeable along the axial direction of the supply roll shafts 15 and 16. 33 is a handle and 34 is a fixture.

Reference numeral 35 denotes an inclined reduction gutter provided below the cleaning roll 22, which is capable of reducing grains through the reduction holes 36 formed by the front plate 7 and the storage tank 2. The operation of the above example will be described. When the measurement signal from the control unit in the operation box 6 is received, the motor 24 is rotationally driven, and the supply rolls 17 and 17 are rotated by interlocking the rotation of the gear 26 at the motor shaft end with the two-stage gear 27 and the gears 29 and 30. Start.

When the feed adjusting plates 31, 31 ... Are set at arbitrary positions in advance, a part of the grain moving in the grain tank 2 is guided by the feed rolls 17, 17 ... The one grain is rolled in and supplied. The rotation of the two-stage gear 27 rotates the electrode rolls 20 and 21 together with the gear 28, so that one grain of the grains supplied from the ends of the supply rolls 17 and 17 is crushed between the electrode rolls 20 and 21. The electric resistance value is detected. In this way, the moisture value can be converted.

The grain that has passed through the electrode rolls 20 and 21 is returned to the storage tank 2 through the inclined reduction gutter 35. still,
Grains in the grain tank 2 gradually flow down to the hot air chamber,
In the hot air chamber, hot air is blown and dried in the meantime. The grain is returned to the grain tank 2 again via the elevator 3 and the predetermined hot air drying is repeated.

During this time, the water content is measured at predetermined intervals, and hot air drying is repeated until a predetermined value is reached. When the preset moisture value is reached, the drying operation is stopped by a signal from the control unit in the operation box 6.
