POLE OF SPRAYING MACHINE Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: pole of the spraying machine has carrying frame 1, mounted on the frame of the spraying machine. Section of the pole with collectors 18 for liquid spraying are connected with carrying frame 1 by double hinges 5 and pullings 6. Carrying frame 1 has horizontal struts 14 with elastic members 15, connecting the pole sections with the frame of the spraying machine. Shock absorbers 8 are mounted on the pole sections. Shock absorbers are connected with carrying frame 1 by hinges 9. Each section of the pole has several parts 2, 3, 4. Edge part 4 of the parts of the pole each section is connected with the rest parts of parts of the section by hinge 11, axis of which is located on horizontal plane perpendicularly to longitudinal axis of the pole. Elastic members 12 and embracing them fixers 13 to limit turning angle of edge parts 4 of the pole each section in vertical plane are mounted in the place of connection of edge parts 4 of each section with the rest parts of the section. Fixers 13 era located with respect to elastic members 12 so, as to be capable to form a clearance. EFFECT: increased reliability and uniformity of liquid distribution. 3 cl, 2 dwg
