Description

TECHNICAL FIELD The present invention relates to a moisture detecting device for grains, which can be used in a dryer for drying grains and the like.

2. Description of the Related Art Conventional techniques and problems to be solved by the invention Conventionally, the grain stored in the grain tank is fed into the detection roll unit and fed by the supply roll as the grain crushing unit of the grain in the moisture detector.

By the way, the above-mentioned supply rolls are provided as a pair of left and right, and since it is a form in which they are provided so as to project into a storage part such as a grain tank of grain, the amount of grain received by the outer peripheral surfaces of the pair of left and right feed rolls is likely to fluctuate, and eventually the detection roll There are fluctuations in the inflow situation of grain into the area.

Means for Solving the Problems Therefore, the present invention forms a helix on the outer peripheral surface, and of the pair of supply rolls 1,1 in which the end portion side is seen above the detection rolls 23,23 for moisture detection. A part of the starting end side is looked into the storage part of the grain, and on the upper side of the supply rolls 1 and 1, in the valley portion where the supply rolls 1 and 1 approach each other, the outer peripheral surface and the grain inflow gap. , And the other parts are arranged so that the feed adjusting plate 19 is positioned in close proximity so as to prevent the inflow of the grain, thereby forming the moisture detecting device for the grain.

Actions and effects of the invention For example, in the case where a moisture measuring device is used in the grain dryer, the stored grains are ridden on the start side of the supply roll by the rotation of the supply rolls 1 and 1 and transferred by the spiral. However, on the way, there is a feed adjusting plate 19, and grain inflow is possible in the valley portions where the left and right feed rolls 1, 1 are close to each other,
In other parts, this inflow can be blocked, and a large amount of excessive grain entrapment can be prevented, so that the necessary grains can be smoothly transferred to the spiral and the grains can be stably supplied to the detection roll unit. it can.

A cleaning roll shaft (26) is provided below the detection rolls (23) and (23) to support metal (13) and (1).
4) The shaft is supported by the cleaning roll shaft (26), the cleaning roll (27) is fixed to the shaft end, and the gear (28) is fixed to the other shaft end. A brush is provided on the surface portion, and the brush comes into contact with the outer peripheral surface portions of the detection rolls (23) and (23). (29) is a motor fixed to the supporting metal (14), and a gear (30) is fixed to the shaft end of the motor (29). The gear (30) and the two-stage gear (2)
It meshes with the large-diameter gear of 4), the large-diameter gear of this two-stage gear (24) meshes with the gears (17), (28), and the gear (17) and the gear (18) The small-diameter gear of the two-stage gear (24) and the gear (25) are meshed with each other, and an inclined plate (31) is provided below the cleaning roll (27) to detect the detection roll (23). ) And (23), the crushed grain detected between the (23) and (23) is guided by the inclined plate (31) through the opening (33) of the grain tank (2) into the grain tank (2) for drying.
