| China is a large grain production country with high yield and large reserves.The grain surface leveling of large granary is an important work of grain storage enterprises,and it is also an important part of the standardization requirements of grain storage enterprises.The traditional grain surface leveling operation is not only time-consuming and laborious,inefficient,but also has security risks.With the increase of labor cost and the demand of building intelligent granary,it is urgent to realize automatic grain warehousing.Therefore,it has broad market prospect and practical value to develop an automatic grain distribution machine instead of traditional technology for grain warehousing and grain surface leveling.This topic is based on a flow type granary grain distribution system,including grain feeding device,and grain conveying and distributing device.Through the whole process control of grain transportation and grain distribution,the whole automation of grain distribution can be realized.The subject mainly carries out the following work :Firstly,the mechanical structure of the grain distribution robot is introduced,and the simulation debugging is carried out according to the experimental device.The feasibility of relevant institutions is verified through experiments and the control basis is obtained.Then,according to the requirements of mechanical design,the selection of electrical control and the design of electrical schematic diagram,the preparation and simulation of PLC program and touch screen screen,and the design of remote data sharing system are carried out.In terms of electrical control,a set of control system is designed with PLC as the control unit,frequency converter and servo motor as the transmission and output execution parts,and the sensor as the signal detection input.The frequency converter is controlled by Mitsubishi CC-Link field bus,and the SSCNET Ⅲ/H servo bus is connected to the servo drive to construct the control system,so as to realize the automatic control goal of the grain distribution robot.Finally,based on the needs of intelligent manufacturing and enterprises to complete the transformation of production digitalization and automation,The upper computer and CIM production intelligent acquisition system are designed.The advantage of this topic is that the automatic grain distribution and information management are used to complete the grain storage and leveling work The automation and intelligence of feeding,distribution and distribution are realized,which meets the needs of industrial 4.0 transformation in enterprises and industries,and provides a model for subsequent industrial applications. |
