Abstract

In order to study the cutting mechanism of sweet potato vine, provide technical support and theoretical basis for the development of sweet potato vine harvesting machinery and improve the resource utilization rate of sweet potato vine, a cutting test bench for sweet potato vine was designed. The test bench consists of two parts: Mechanical part and measurement-control part. In this study, the requirements for the mechanical structure design of the test bench are first put forward and then the structure and hardware of the measurement control system are described. Using this platform, the cutting experiment of sweet potato vine was carried out and the effects of cutter roller speed, conveying speed and feeding amount on cutting torque, cutting power and cutting force were deeply discussed. The test shows that the sweet potato cutting test bench not only realizes the visualization of the test process, but also has the characteristics of small measurement error, stable operation and simple operation. Through experiments, when the cutter roller speed is 1266 r·min-1, the conveying speed is 0.54 m·s-1 and the feeding amount is 1.0 kg, the sweet potato vine cutter has excellent working performance such as high processing efficiency and low energy consumption. The platform can provide reliable scientific basis for cutter design and power selection of sweet potato vine harvesting machinery.
