FORESTRY THINNING MACHINE Russian patent published in 2021 - IPC A01G23/02 

FIELD: forestry.

SUBSTANCE: invention relates to forestry, in particular to equipment for felling during forest maintenance. The machine for thinning forestry contains a platform, a cutting mechanism and a pulling mechanism. At the top of the platform, there is a pull-through roller mounted on the shaft of the bearing assembly, on which the pressure roller frame is also hingedly mounted with the possibility of changing in the vertical plane using a transverse hydraulic cylinder, and the pressure roller is mounted on bearings on a rod that is hinged at the top of the frame with the ability to change horizontally plane using a longitudinal hydraulic cylinder. Wherein next to the pulling device, a grinder is mounted, consisting of a bearing assembly, on the shaft of which a set of circular saw blades is installed on one side and a hydraulic motor on the other. At the same time, a cutting mechanism in the form of hydraulic shears is mounted at the bottom of the platform, and the drives of the pull-through and chopper mechanisms are connected to the hydraulic motor by means of belt drives.

EFFECT: material consumption of the device is reduced, the risk of forest damage by biological diseases is reduced, and the risk of fires is also reduced.
