流動中の穀粒についての水分計測は、誤差のため
実用性に欠ける問題点があり、正確な水分計測の
できる水分測定装置が要望される処であつた。 In general, the fatal flaw of automatic moisture meters that measure grain moisture by detecting grains using capacitance is that the density of the grain moisture measurement chamber containing the cathode and anode is poor due to the roughness and density of the grain surface. There are large changes depending on the degree of moisture content and the shape and size of grains, and the difference in density causes large errors in moisture values. In particular, measuring the moisture content of flowing grains has the problem of being impractical due to errors, and there is a need for a moisture measuring device that can accurately measure moisture content.

分測定装置を提供することを目的とする。 The present invention is an improvement made in view of the above-mentioned points, in which a pressing element of a sliding tube is inserted into a grain tank, and the grain layer in the grain tank is pressed in a compressed manner to improve the grain distribution structure. The moisture sensor attached to the presser measures the capacitance of the grain to detect the grain moisture value, and the weight change value of the amount of grain supplied to the weighing device is sent to the weighing detector. The grain moisture value detected by the moisture sensor and the grain weight detection value detected by the weighing detector are communicated to the control circuit, and the control circuit determines whether the moisture detection value is increased or decreased from the reference weight value. The changed weight change value is corrected and calculated for changes in the coarse density of the grain layer in the grain tank, changes in grain shape, etc.
It is an object of the present invention to provide a moisture measuring device capable of accurately measuring moisture without error.
