2. Description of the Related Art Conventionally, in a grain sorting apparatus, there is Japanese Utility Model Application Laid-Open No. 58-183291 as an apparatus in which the rotation center of the sorting cylinder is eccentric from the center of the sorting cylinder. The axis of the rotary shaft is eccentric from the center of the sorting cylinder on both the grain supply side and the grain discharge side. However, at the outlet near the end of sorting, excessive agitation increases the range of discharge of grains from the sorting cylinder, requiring a grain collecting plate for this purpose, and reducing the number of collisions with the sorting cylinder for soybeans and the like. There is a fear that it may increase and cause scratches. Japanese Utility Model Application Publication No. Sho 56-106871 discloses an example in which a rotary scraper for removing grains stuck on the outer peripheral surface of the sorting cylinder is disclosed. However, the rotary shaft of the rotary scraper is located at the center of the scraper.

The conventional sticking amount detecting device 50 has rotating blades in the storage device 43 at a portion considered to be full, and when the load increases, a switch operates to detect the full amount. Alternatively, there is an electrostatic capacitance type that detects the presence or absence of a grain by detecting the electric resistance of a probe, but in any case, the detection position range of the grain is small.

In order to solve the above-mentioned problem, by taking the above-mentioned measures, when the grain has not yet been stuck,
Wind speed (including air flow) due to low ventilation resistance in the pipe
Although the pressure is fast or the pressure is small, the grains gradually accumulate in the storage device 43 after the filling, and when the pipe 51 is buried, the intake hole 51a provided in the pipe 51 is closed, and the ventilation resistance increases. As a result, the wind speed and air volume decrease, and conversely, the pressure increases. This wind speed or pressure is detected by the sensor 53 and output as a detection signal to the insertion amount calculating means 55,
The insertion amount calculation means 55 calculates the insertion amount from the relationship between the preset kernel insertion amount and the wind speed or pressure detection signal.

In this case, since the sensor 53 does not directly contact the grain, no mechanical damage occurs due to impact or the like.
In addition, a stable measurement can be performed without causing a malfunction due to the adhesion of the grain, and the important insertion amount for setting the drying condition can be accurately calculated.
