Study On Conveying Performance Of Maize Straw On The Type LS Screw Conveyor

Screw conveyor is a continuous conveyor machinery, it does not have a flexible traction member, rotating spiral makes its use of materials produced between the screw shaft relative motion to achieve the purpose of transportation of materials, mixing screw conveyor can also be completed according to the actual needs, compression, heat transport, so it has a very wide range and it also becomes one of the important crop processing and utilization of equipment. Greater yield of corn stalks, it also has a variety of ways, this article is mainly horizontal screw conveyor for conveying crumbled corn stalks after research conducted, it has important implications for the processing and utilization of crop stalks.This paper studies the level of corn stalks after crumple screw conveyor performance.First, according to some empirical formula and the characteristics of the helical conveying corn stalks, main parameters of derived screw conveyor, the corresponding design of the test device, and determine the speed, pitch, and the moisture content of the test factors, throughput and power transfer performance index as a measure.Then, the influencing factors and metrics to determine the test program were conducted univariate and multivariate combinations of orthogonal experimental test, based on test data derived from the inherent speed, pitch, moisture content and throughput power consumption between law.Finally, the analysis of the experimental data obtained SPASS the following rules:(1) Within the speed range of the research, the speed, the greater the throughput and power consumption, moisture content, the greater the throughput and power; throughput and power consumption increases with increasing pitch; through orthogonal test results obtained out of the speed, pitch, affect the moisture content of the test indicators were significantly affected by primary and secondary order are:speed, moisture content, pitch; for green feed conveyor speed should be selected50r/min, the pitch should be selected200mm, moisture content at72%, productivity reached2.10t/h, power was203.38w, it was best.Therefore, the study of this paper about screw conveyor, transporting fiber materials provide a reliable basis and certain guiding significance for the processing and utilization of crops.
