MULCH AND FERTILIZER SPREADER Russian patent published in 2004 - IPC

FIELD: forestry. SUBSTANCE: proposed invention can be used in nurseries. Mulch and fertilizer spreader has body with bottom in form of conveyor, metering and leveling gates and drive. Spreading drum is arranged under outlet part of feeding conveyor. Body of spreader accommodates k leveling cross gates where K is whole number determined as ratio of l/H where l is length of conveyor; H is height of material filled in body at 1<k≤3, and lower edge of leveling gates is arranged at distance h from conveyor flights found from where ha is distance from surface of conveyor to lower edge of metering gate, m; V_sp is speed of machine, m/s; B_sp is width of spread material strip, m; h_sp is thickness of spread material layer, m; V_con is speed of conveyor, m/s; B_con is width of conveyor, m; h is distance from surface of conveyor to lower edge of leveling gate, m. Invention makes it possible to reduce discreteness of delivery of material (to increase uniformity of material spreading at length of pass). EFFECT: increased service life of machine, reduced load on its drive and provision of load leveling. 1 dwg
