Abstract

Abstract. In order to realize the real-time monitoring of the grain condition, grain condition information should be collected during storage operations. A drill-in granary grain condition detector which can drill into a grain pile in a granary is proposed. The kinematic models of four Archimedes screw mechanisms were established, and the motion characteristics of grain particles in spiral grooves were described. Several groups of single variable simulation experiments are designed to discuss the important factors affecting the motion performance of the detector. Based on a discrete element method with multi-body dynamics (DEM-MBD) simulation calculation, the force and velocity change images of grain particles were obtained to verify the feasibility of the scheme. The steering function of the detector is verified by simulation, and the relationship between the steering radius and the screw rotation speed difference is analyzed. The results show that the drill-in granary grain condition detector can move forward and turn when it is immersed in the grain pile. It has the characteristics of excellent flexibility and a high degree of freedom. It compensates for the current situation in which robots cannot go deep inside the grain pile and complete the steering.

粮仓粮情检测仪钻头结构参数及运动特性研究

摘要为了实现对粮食状况的实时监测，应在储存过程中收集粮食状况信息。提出了一种可钻入粮仓粮堆的粮仓粮况检测器。建立了四种阿基米德螺旋机构的运动学模型，描述了颗粒在螺旋槽中的运动特性。设计了几组单变量模拟实验，讨论了影响探测器运动性能的重要因素。基于离散元多体动力学（DEM-MBD）仿真计算，获得了颗粒的力和速度变化图像，验证了该方案的可行性。通过仿真验证了检测器的转向功能，分析了转向半径与螺杆转速差之间的关系。结果表明，粮仓颗粒状态检测仪中的钻头在浸入到桩体中时可以向前移动和转动。它具有极好的灵活性和高度的自由度。它弥补了机器人无法深入谷物堆并完成转向的现状。

期刊介绍： The journal Mechanical Sciences (MS) is an international forum for the dissemination of original contributions in the field of theoretical and applied mechanics. Its main ambition is to provide a platform for young researchers to build up a portfolio of high-quality peer-reviewed journal articles. To this end we employ an open-access publication model with moderate page charges, aiming for fast publication and great citation opportunities. A large board of reputable editors makes this possible. The journal will also publish special issues dealing with the current state of the art and future research directions in mechanical sciences. While in-depth research articles are preferred, review articles and short communications will also be considered. We intend and believe to provide a means of publication which complements established journals in the field.
