Abstract：In order to study the power consumption under different combinations of forward speed, rotational speed, opening furrow angle and depth of furrow, a kind of soil-bin test device of vertical spiral opener was introduced for the soil-bin experimental test. With computer and acquisition cards as control center, a measurement and control software were programmed based on LabVIEW to collect, display and analyze the data of motional parameters such as rotational speed, torque and power consumption, et al. The device were tested in the soil-bin under the experimental conditions considering 250 r/min as rotational speed, 0° as the opening furrow angle, 250 mm as the depth of furrow, and 3 m/min, 4 m/min, 5 m/min as the forward speed respectively. The cutting power consumption obtained by theoretical model can be used to validate the experimental results. The test results show that the device can simulate the whole process of the vertical spiral opener cutting the soil, and the maximum error between calculated and experimental values is 11.05%.
