The method of determination of the safety zone between the rototiller cover and rotor
Journal Title: Annals of Warsaw University of Life Sciences- SGGW - Agriculture - Year 2015, Vol 66, Issue 66
Abstract
The objective of the study was to develop an analytical method of determination of the safety zone between the rear cover and the rotor of the rototiller for various cover types. Using the sizes and relationships between characteristic points of the rotor and the cover of the machine, an algorithm was developed to calculate the safety zone, which is applicable to the entire range of settings of the rear cover and the working depth. The safety zone was assumed to be the horizontal distance between the end of the rear cover of the rotor from the path of movement of the cutting blades, according to the requirements of the harmonized standard EN ISO 4254-5:2009+AC 2011. Determination of this distance requires measurement of: the cover mounting height, the length of the section connecting the rotor rotation axis and the rear edge of the cover and the diameter of the rotor with knives. The safety zone within the area of the rear cover of the machine was verified for three types of rototillers with varying cover structures. The analysis conducted showed that use of a two-component rear cover with an articulated mechanism allows for maintaining of the required safety zone regardless of the positioning of the cover and the working depth.
