| Abstract: | Ensilage maize combine can ingather corn ear, as well as bundle and ensilage corn stalk when it is used for corn harvest. In order to enhance operation efficiency of ensilage harvester, and to reduce the operating burden of driver, an automatic control system on feedstock and rope-send was designed, composed of three parts, i.e., sensor detection element, control circuit and implementation mechanism. Four-way change-over switch was used as detection element of sensor, and combined with RS de-twitter circuit, to improve the reliability of the control system effectively. The implementation components that were composed of two electromagnetic clutches responded to the control circuit output, and ultimately actualized the real time control of feeding stalk and sending rope. Experiments show that the designed system can work accurately and reliably, with the baling rate to 100%, compared with manual control, the veracity of bale density control is strengthened effectively, and operating efficiency of the machine is improved by 20 %. |
