【摘要】 我国现有的深根茎中药材收获机械简易,工作效率低,作业质量差,成为中药材种植业发展的一个瓶颈。为此,以AT89C52单片机为控制核心,以开关传感器为检测手段,结合自动控制原理设计了深根茎中药材收获机夹持带转速自动调节系统。该系统能使夹持带转速实时跟踪机器作业速度变化,从而大大提高了药材的收获效率,降低了药材损失率和破损率。室内土槽试验表明,此控制系统达到了预期设计要求。更多还原

【Abstract】 Chinese herbal medicine harvester in agricultural production plays an increasingly important role in.However,our Chinese herbal medicine harvester is still poor work quality,low efficiency,fault etc.Good performance,automation,high intelligent degree of the Chinese herbal medicine harvester will be the aspect of development in the future.Therefore,this paper takes the SCM as core,combined with automatic control theory to the design of the traditional Chinese medicine harvesting machine clamping belt automatic speed control system.The system according to the operation of the machine speed changes,regulation of harvesting machine clamping belt speed,the machine speed and grip tape speed to achieve the best match,thus greatly improving the performance of the harvesting machine.更多还原
