The Tatarstan company "2P Engineering" has patented a forest fire ground thrower that can use solar energy to additionally power the working mechanism. The machine is based on a tractor with a high-torque hydraulic motor installed at the rear.
The hydraulic motor spins a flywheel with milling cutters that dig into the soil and throw soil into the area of a ground fire. The operator can change the working depth of the mechanism with a hydraulic cylinder.
An unusual part of the design is its own solar power plant directly on the tractor. A group of photovoltaic modules equipped with a sun tracking system is placed on the mast around the support. Electricity from the photovoltaic modules enters a system with a battery that powers an additional electric motor.
The main mechanical work is performed by the hydraulic drive, and the electrical system provides it with additional energy. The developers expect this to reduce energy consumption and increase the operating time of the ground thrower.
