Small snow cutters
Ráheľ, Dušan ; Prokeš, František (oponent) ; Brandejs, Jan (vedoucí práce)
The bachelor thesis deals with the subject of snowblowers. It describes their origin, evolution a current applications. It presents development and technical details of all snowblower sizes, ranging from smallest ones, driven manually by operating personal, to the largest, attached to the trains. The work explains modern hybrid snowblower powertrain. The combination of gasoline and electric engine proves to achieve substantial reduction of fuel consumption at unaffected efficacy of snow removal. The second part of work deals with our proposed novel method of snow removal, which employs its volume compression. A series of experiments were done in order to establish the relation between the exerted force and resulted compression of snow of various initial mass density. We have found that pressure smaller than 0,5 MPa is capable in average to reduce the snow volume to 45% of the initial value.
