Studies on the Separating Mechanism of the Digger (II)

Fundamental experiment using Radio-Isotope

Abstract

As a fundamental study on the separating mechanism of the digger, the count-rates of potato, clod and stone which were formed into known thickness, were measured at the stationary condition using Gamma-attenuation detection apparatus with ¹³⁷C_s.
1. By using equivalent thickness of iron plate to that of potato, clod and stone, the linear calibration lines which indicated the possible range of separation were obtained (Fig. 7).
2. The possible range of separation which was obtained from the linear calibration lines almost coincided with the experimental results by the trial electric circuit for separating device with ON-OFF mechanism.
