Abstract

This paper presents the results of experimental research on the development and substantiation of parameters and operating modes of the drive mechanism of the cutting apparatus in a mower with a double knife stroke.

A structural and technological scheme of the drive mechanism of the cutting device of the segment-finger type mower has been developed, in which a double stroke of the cutting device knife is provided. Analytical relationships were obtained to determine the knife stroke, speed and acceleration. Based on the results of theoretical and experimental studies, the main parameters of the mower drive mechanism were substantiated. Based on the condition of a high-quality cut of plants, at a minimum grass cutting speed, the minimum crank shaft speed was determined. By calculation, the feed area and the load area of the cutter for normal cutting with a double cut of the knife are determined. Analytical relationships were obtained to determine the power required to drive the cutterbar of a mower with a double knife stroke. Based on the research results, the main parameters of the mower with an improved drive are substantiated. An experimental sample was made and preliminary tests of the drive mechanism were carried out, agrotechnical and energy indicators of the mower operation were determined.
