Abstract

To remove unwanted tree and shrub vegetation, it is necessary to use mechanized implements aggregated with traction means - tractors. The power consumption of the drive of these tools depends on their mass and the principles of the cutting process. Currently, mulchers, which are designed to grind felling residues with a diameter of tens of centimeters, remove shrubs with a diameter of up to several centimeters, which leads to unreasonably high costs for this type of work. The article studies the designs of frames and working bodies of brush cutters, which are a rotor rotating in a horizontal plane with a knife fixed on a flexible connection or hinge. On the basis of the structures, hypotheses have been put forward about the advisability of using the considered types of working bodies when cutting tree and shrub vegetation, taking into account its diameter. Using the presented connections between the types of working bodies and their ability to cut tree and shrub vegetation, it was revealed the possibility of developing narrowly focused mathematical models, which will reduce the energy consumption of hedge trimmers and increase their efficiency. The presented designs of rotors themselves are also insufficiently studied from the point of view of kinematics and dynamics of movement of their links, which is of certain scientific interest.
