“…The results are in agreement to similar relationship reported by A. Kumar et al. (2020). However, shear strength for all cultivars decreased from upper to the lower part of the stem, because force per unit area decreased from the upper to the lower internodes, as in accordance to previous findings of Zareiforoush et al.…”

A device was developed for on‐field cutting energy measurement of cereal crops. Physical, engineering, and anatomical properties of prominent rice (Oryza sativa L.) cultivars of India were studied at different stem positions using a factorial CRD design. The effects of changes in different operational parameters, including blade bevel angle (15°, 20°, and 25°), cutting angle (25°, 30°, and 35°) and cutting velocity (2.9, 3.44, and 4.1 m s−1) on cutting force and cutting energy of rice stalk were also studied. Cutting angle indicated the angle of inclination of cutting edge to the horizontal at blade‐crop interface. The assessment of these properties and parameters in relation to crop cutting energy, led to the development of a smart device for energy measurement up to a size of three skills. This device consisted of a compression system, crop holding unit, cutting unit, and sensors to measure the force, speed, and cutting height. The device's measurement abilities were evaluated with wheat (Triticum aestivum L.) stalks at different cutting speeds (0.83, 1.16, and 1.5 m s−1 and stem heights (10, 20, and 30 cm from ground). Values for cutting force and energy ranged from 1.85 to 1.45 N and 10.81 to 8.48 N mm–1, respectively. At all stem heights, the cutting force and cutting energy ranged from 1.79 to 1.44 N and 11.92 to 6.74 N mm–1, respectively. The ultrasonic sensor provided real time cutting height data with an accuracy of 97.5%, while the gyroscope sensor had an accuracy of 94.29% for on‐field cutting angle measurement.

This article describes the influence of dynamic bridging in the unloading of a hopper at a processing plant on the grain flow homogeneity in a convective-microwave zone. In accordance with calculation methods for unloading hoppers, the parameters of the hopper unit and those of the outlet hole insuring that grain flows without static bridging formation is defined. It was found that moisture content fluctuations do not affect the process of grain transport. The equation for dynamic bridging rise depending on its position on the vertical axis of the unloading hopper has been deduced that enables the definition of the inhomogeneity of grain flow from its outlet hole. Calculations show that a certain inhomogeneity occurred between the right and the left parts of the unloading hopper in relation to its vertical axis in the course of grain discharging. This effect underlies the inhomogeneity of grain processing and reduction of its effectiveness in convective-microwave zones. An experimental model of unloading the hopper has been manufactured in order to perform investigational studies. The results of studies have completely confirmed the hypotheses. It has been found that dynamic bridge formation in unloading of the hopper results in the inhomogeneity of grain flow in convective-microwave zone.

To simulate the bending behaviour of paddy straw at varied moisture contents after crop harvesting, we created a flexible paddy straw specimen model based on the Hertz–Mindlin with parallel contact bonding model using the discrete element model (DEM) approach. The research presented in this study aims to investigate a new approach called Definitive Screening Design (DSD) for parameterizing and screening the most significant parameters of the DEM model. This investigation will specifically focus on the three-point bending test as a means of parameterization, and the shear plate test will be used for validation purposes. In addition, the most influential DEM parameters were optimized using another Design of Experiments approach called Central Composite Design. The findings from the DSD indicated that parameters such as bonded disk scale, normal stiffness, and shear stiffness have the highest impact on the bending force, while the coefficient of static friction (Straw-Steel) has the least effect. The three bonding parameters were respectively calibrated with the loading rate (0.42, 0.5, and 0.58 mm s−1) and a good agreement between actual and simulated shear force at moisture content M1—35 ± 3.4%, M2—24 ± 2.2% and M3—17 ± 2.6%. Modelled stem helps simulate the straw with low error and increases the accuracy of the simulation. The validated model, with an average relative error of 5.43, 7.63, and 8.86 per cent, produced reasonable agreement between measured and simulated shear force value and loading rate.
