Further, a grain return port 14 serving as an opening is provided below the grain take-out port 12. And the second,
As shown in FIG. 3, a mounting base 20 for a moisture meter 18, which is a moisture detection device, is fixed from the outside of one side wall 2a of the grain lifting machine 2 with a fixing device 16 such as a bolt, and the mounting base 20 for the moisture meter 18, which is a moisture detection device, is fixed from the outside of one side wall 2a of the grain lifting machine 2. 14 is formed. Mounting platform 2 in the middle of this taxiway 22
As shown in FIG. 4, a sample collection port 24 is provided on the table surface 20a of the 0, and as shown in FIG. A guide plate 26 is provided to gradually narrow the width of the guideway 22. Further, as shown in FIG. 2, an inclined plate 30 is integrally provided below the sample collection port 24 of the guideway 22, and is attached so as to be openable and closable by a hinge 28. Then, as shown in FIG. 3, a peephole 32 is bored in the side surface of the mount 20 near the sample collection port 24,
This viewing window 32 is provided with a transparent lid 34 that can be attached or detached or opened and closed. Base surface 20a of the mounting base 20
The moisture meter 18 is attached to the grain to complete preparations for measuring the moisture content of the grains.

The reference numeral 36 is a sample waste receptacle into which the sample waste is placed after the moisture content has been measured by the moisture meter 18, and the reference numeral 38 is a sample waste receptacle placed at the bottom of the grain outlet 12 in order to prevent foreign matter from getting entangled with one side wall 2a of the grain lifting machine 2. The attached cover plate,
40 is a lower electrode of the moisture meter which serves as a sample collection plate of the moisture meter 18.

Next, the effect will be explained.

During the grain hoisting operation, a part of the grains is thrown up by the bucket 8, and only the grains excluding the grains in the grains are thrown up to a high position. Then, as shown in FIG. 2, a part of the sized grain flows out into the guide path 22 from the grain outlet 12 provided below the top dead center of the grain. Also,
The grains falling through the guiding path 22 are collected by a guide plate 26 and reach the sample collection location. At this sample sampling location, the moisture meter lower electrode 40 of the moisture meter 18 protrudes from the sample sampling port 24 into the guiding path 22 to collect the sample. Further, the grains that are not sampled at this sampling point further fall down the guideway 22, pass through the inclined plate 30, and are detoured back into the grain lifting machine 2 through the grain return port 14.

By forming a peephole 32 with a transparent lid 34 on the side of the mount 20 near the sample collection point, the state of sample collection and the state of attachment of foreign matter such as straw and rice gruel can be monitored through the peephole 32. be able to. In addition, when foreign matter becomes stuck and blocks the taxiway 22, the transparent lid 34 is removed even during grain frying operation, and a hand or a scraping stick is inserted through the viewing window 32 to remove the foreign matter and clear the taxiway 22. The blockage can be easily released.

As shown by the dashed line in FIG. 2, the inclined plate 30 is provided so that it can be manually opened and closed about the hinge 28, so that the sample can be deflected in and out, and the sample grains can be removed from the machine. Extraction and return of extracted grains can be easily performed.
