JPH067089B2 - Test grain extractor - Google Patents

Description

TECHNICAL FIELD The present invention relates to a device for taking out test grains, which allows a small amount of test grains to be taken out from a grain dryer, a grain storage tank, a huller, or the like. Therefore, it can be used for detecting the moisture content of a grain in a grain adjusting machine, a grain adjusting plant, etc., and for inspecting other grains.

2. Description of the Related Art A small amount of a small amount of grain is taken out from a grain tank of a dryer simply by opening and closing an outlet.

Problems to be Solved by the Invention Since a large amount of straw debris, dust and the like are mixed in the grain, when a small amount of test grains are accurately taken out from the grain, the straw debris is Etc. are likely to get in the way, and, in addition, as in the case of supplying the extracted grain to the grain moisture meter to measure the moisture content of the grain, straw dust, dust, etc. If there is a large amount of mixed water, it may not be possible to accurately detect the water content of the grain. The present invention is intended to eliminate such defects and to accurately extract only the test grains.

MEANS FOR SOLVING PROBLEMS The present invention is directed to the falling grain (1) on both left and right sides of an inclined plate (3) having an appropriate width which guides the grain (1) to flow down to a drop opening (2) at a lower end. 1) A device for taking out test grains is provided with a side groove (5) for dropping straw waste (4) mixed in 1).

The operation and effect of the invention The grain that is guided down the upper surface of the inclined plate (3) and flows down is supplied to the drop opening (2) for testing, and straw grains and dust are contained in the grain. , Etc., these straw chips will fall into one of the side grooves (5) provided on both the left and right sides during the flow down and be separated, and the width and length of this inclined plate (3), etc. By this, a small number of grains can be taken out while sorting them to a required number, the structure can be simplified, and clogging of grains at the time of taking out can be reduced.

Example In addition, in the illustrated example, (6) is a grain raising machine of a grain dryer,
It receives the flowing down of the heated grain while heating it, raises the grain, and returns it to the drying chamber and supplies it again. The grain extracting chamber (7) is provided on one side of this grain raising machine (6). The slant plate (3) is projected, and the upper end of the slant plate (3) is directed toward the inside of the grain raising machine (6), and the slant plate (3) is inclined downward to the side of this grain extracting chamber (7). I am letting you. The side groove (5) opens both left and right end edges of the inclined plate (3), and a return plate (8) inclined in the opposite direction to the inclined plate (3) is provided on the lower side of the side groove (5). The grain, straw waste, and the like dropped from the grain are returned from the grain extraction chamber (7) to the grain elevator (6) side. A drop port (2) is provided at the lower end of the inclined plate (3), and a drop port communicating with the drop port (2) is provided at the upper end of the return plate (8) to distribute the machine (9). However, even if straw chips fall from this drop port (2), they can be guided to the return plate (8).

A guide tube (10) is provided below the drop opening (2),
Further, a feeding spiral (11) is provided at the lower end of the guide cylinder (10) to supply the test grain onto the moisture detector (12). A guide valve (13) is provided at the lower end of the guide cylinder (10) so that the angle can be adjusted by a solenoid (14), and the feeding spiral (11) is provided by the inclination of the guide valve (13) or the number of times of rocking.
The number of grains supplied to the side is adjusted, and the supply state is adjusted.

The feeding spiral (11) has a spiral groove (15) on its outer peripheral surface, and a guide plate (18) along one side surface. A concave interval (16) is provided between the spiral grooves (15) on the terminal side of the feeding spiral (11), and the grains derailed from the spiral groove (15) are provided in this interval (16).
It is intended to be dropped from. The terminal end of the spiral (11) has a structure in which the grain is dropped from the inlet (19) of the case (17) to the inside of the moisture detector (12) and drops each grain on the moisture detector (12). ) Consists of a pair of left and right electrode rolls, and detects the moisture value while crushing each grain.

Grains that are sublimated in the sublimation machine (6) during the grain drying operation are partially received by the upper surface of the inclined plate (3) while falling off while overflowing from the bucket, and the extraction chamber (7). While being guided to the guide pipe (10) from the drop port (2), some grains and straw debris are moved to the gutters (5) on the inclined plate (3) and moved downward. Guided by the side return plate (8), it is returned into the grain raising machine (6).

The grain supplied from the lower end of the guide cylinder (10) by the guide cylinder (13) between the feeding spiral (11) and the guide plate (18) is placed in the spiral groove (15) of the rotating spiral (11). It is guided to fit and is fed out to the inlet (19) of the case (17) and the moisture detector (12).
One grain is supplied on the top and moisture is detected.
