HEADER Russian patent published in 2004 - IPC

FIELD: agricultural engineering, in particular cereal crop harvesting equipment. SUBSTANCE: header has cutterbar and reel with reel mounting height indicator made in the form of scale and horizontal rod. Rod is spaced from reel axis by distance ρ determined from formula: where R is reel radius, m; r_w is wheel rolling radius, m; i_n is ratio of transmission from engine shaft to reel; i_w is ratio of transmission from engine shaft to drive wheel; h is height of standing grain, m; l is average length of stalk, m. EFFECT: reduced losses of grain standing in plane deflected from vertical plane owing to displacement of reel plank in parallel with ears at minimal interference with of ears. 3 dwg
