The Method and Experiment of Kinetic Determination for the Rotary Soil-Engaging Components of Agricultural Machinery Using a Compacting Device in a Paddy Field as an Example

In order to explore the influence of soil force on rotary soil-engaging components during their operation, a kinetic parameter measurement system of rotary soil-engaging components was developed via the sensor strain measurement technique. By taking a single-sided compacting ridge device as an example, the kinetic experiment was carried out on the operation parameters of the compacting device and obtained the variation law of the force of the soil on the pinnae. ADAMS software was used to simulate the operation of the compacting device under different experimental factors (soil moisture content, forward speed of the ridge device, and the rotation speed of the compacting device), and the test data were obtained; the experiment was carried out with the forward speed of the soil tanker and the rotation speed of the compacting device as the experimental factors, and the average of the force of soil on the pinnae and the firmness value of the ridge were the experimental indicators. The results showed that under a moisture content of 27%, the forward speed of the device was 0.8 km center dot h(-1), the maximum firmness of the ridge was 1233.21 kPa, the minimum firmness of the ridge was 953.85 kPa, and the coefficient of variation of the stability of the firmness value of the ridge was 8.04; the force of the pinnae on the soil increased with an increase in the forward speed of the soil tanker, and the variation range of the force was 2838.1-5695.2 N. It was verified that the design of this operation parameter measurement system for rotary soil-engaging components meets the practical requirements and also provides an important reference for the measurement of the relevant parameters of similar rotary soil-engaging components.
