| 针对现有棉花打顶机械作业过程中存在棉花高度仿形效果差，漏打顶、过打顶严重，智能化水平低等问题，提出了检测装置与打顶装置分开、升降动力与切割动力分开的方案，研制了一种基于FPGA控制系统的3MDZJ-1型棉花智能精准打顶机。作业过程中，检测装置对棉花高度进行检测，控制系统依据作业速度控制打顶装置的响应升降时间，实现定量升降；触屏控制系统能够实时显示作业速度、作业面积及监控棉花打顶过程。田间试验表明：整机结构稳定，机具作业速度在3.24 km·h-1内时，打顶率在88％以上，打顶量接近设定值7 cm，符合设计要求，为棉花打顶机械化及智能化提供了技术支持。 |

| Aimed at the existing problems in the operating process of cutting cotton top machine as poor effect of simulating cotton height, missed out cutting top, over cutting top and low intelligence level etc, proposed the scheme of separating the detection device and cutting top device, and separating the lifting power and cutting power, developed the 3MDZJ-1Type intelligent precision cutting cotton top machine based on the FPGA control system. In the operating process, the detection device is checking the cotton height, the control system is responding the lifting time according to the operating speed to cutting top device to realize the quantitative lifting.The touch screen control system can be actually displayed the operating speed, working areas and monitored the process of cutting cotton top. The field test indicated that the whole structure of machine was stabilization, when the machine operating speed was within 3.24 km·h-1, the cutting top rate was more than 88%, the cutting top volume was close to set value 7 cm, accord with the design requirements. It can be provided the technical support for the mechanization of cutting cotton top and intellectualization. |
