中文摘要:
      为实现水稻联合收割机脱粒滚筒实时喂入量监测,基于薄膜传感器设计了一种脱粒滚筒喂入量测量系统,其原理为通过薄膜传感器测出滚筒顶盖侧边因喂入量变化而产生的受力变化。以额定喂入量为0.8 kg/s的小型横轴流脱粒滚筒为试验对象,以成熟的晚籼98和传奇丰两优1号水稻为主要试验材料,在转速分别为650、800、950、1 100 r/min、喂入量为0.2~0.8 kg/s的条件下开展台架试验,结果显示:薄膜传感器采集的实时信号与实时喂入量显著相关,对喂入量和传感器信号进行线性关系拟合,拟合效果较好。试验结果表明,设计的测量系统可以通过传感器信号对喂入量进行测量。
英文摘要:
      A threshing drum feeding measuring system is designed based on the film sensor to realize the real time feeding volume monitoring of the threshing drum of rice combine harvester. The system can monitor the working state of threshing drum and assist in determining the current real time feeding quantity by using the thin film sensors to measure the force on the top cover. The bench test was carried out under conditions of 1 100 r/min and a feed rate of 0.2 to 0.8 kg/s,using a small horizontal axial flow threshing drum with a rated feed rate of 0.8 kg/s as test object,the mature Late indica rice 98 and Chuanqi Fengliangyou 1 rice as test materials with the rotational speeds of 650 r/min,800 r/min,950 r/min,respectively. The rated feeding capacity of the platform detachment device was 0.8 kg/s. The results showed that the film sensor was collected. Real time signal was significantly correlated with real time feeding. The linear relationship between feeding amount and sensor signal was fitted with good fitting effect. It is indicated that the measuring system designed can measure feeding amount through sensor signal.
