Abstract:
Dibble-type planting device is a working part of dibble-type transplanter which is in direct contact with soil,its performance and efficiency are affected by its shape,size and operating parameters directly.In order to further study influence of size and operating parameters of dibble-type planting device on hole-forming resistance,a testing system for dibble-type planting device was designed based on LabVIEW.Hardware system of hole-forming resistance measurement was built with data acquisition card,pressure sensor and torque sensor,system monitoring software was developed on LabVIEW platform,and DC motor was used as power source of planting device.The test was carried out on test platform of hole-forming resistance for dibble-type planting device.Test results showed that the system could collect data of hole-forming resistance,torque and rotation speed stably in real time.So it could provide a basis for optimal design of dibble-type planting device.
