| Title of the article | Power analysis of high-speed cutting machine |
| Abstract. | Problem statement. To create a powerful root system and strong turf, road slopes are sown with grass or they grow naturally with various grass and shrubs, which requires a certain care for their maintenance, including mow. Famous domestic cutting machines are not always suitable for mowing non-uniform vegetation. They have limited cutting speeds of stems, large inertial moments, high energy costs, poor shrubs, etc. The purpose of the study is to develop a universal high-speed cutting apparatus for mowing grasses and shrub plantings of slopes, devoid of the drawbacks of known apparatuses, to conduct force analysis and optimization of force effects. Results. As a result of the study, a new design of a high-speed cutting apparatus based on a flat parallelogram mechanism, a connecting rod of which acts as a carrier of a knife strip with segments, providing high cutting speeds without friction with opposing plates, determined the pressure of moving links on the frame and the method of eliminating dynamic oscillations. Conclusions. The significance of the results obtained for the construction industry is to create a new effective high-speed cutting apparatus for mowing grass and bushes of road slopes. |
