FIELD: ice and snow cleaners. ^ SUBSTANCE: invention relates to gas-jet machines designed for cleaning air fields from ice and snow. Proposed head 1 for gas-jet machine contains housing formed by upper wall 3, lower wall 4 and side walls limiting space with outlet slot, and vertical partitions 2 arranged in parallel with side walls and dividing space into compartments. Upper and lower walls are made curvilinear, and edges of outlet sections of compartments are formed so that angle of outlet of gas flows 5 relative to horizontal surface 6 to be cleaned changes from 30-35o to 0o in last two compartments in direction of movement of gas-jet machine. ^ EFFECT: improved efficiency of cleaning. ^ 1 dwg |
