BIOHUMUS SPREADING TOOL Russian patent published in 2004 - IPC

FIELD: agricultural engineering, in particular, working tools for centrifugal fertilizer spreaders. SUBSTANCE: biohumus spreading tool has frame, horizontal rotating disk rigidly fixed on hollow shaft, flexible curved blades mounted on continuous inner shaft. Flat knives and inclined discharge blades are arranged on upper end of inner shaft so as to provide grinding of biohumus crumbles and spilling of particles inside grinding chamber, which is made in the form of truncated cone and mounted on frame in axially aligned relation with respect to hollow and inner continuous shafts. Grinding chamber bottom is formed of immovable sector and two gates arranged at its sides and provided with flanges extending in circular path and downward along cylindrical shell attached in lower part of grinding chamber to its side surface. Gates are fixed in predetermined position by bolts in cylindrical shell slots. Immovable sector has side protrusions arranged at its apex and guiding recess for supporting gates arranged in central part and moving gates under immovable sector. Guide formed as curved plate is fixed on frame in zone adjoining immovable sector at the level of disk so that gap between guide and disk is reducing in direction of rotation. Inner and outer shafts are driven separately for rotation. EFFECT: increased efficiency, improved quality of applying biohumus in accordance with agronomical and process requirements and uniform spreading of biohumus. 3 dwg
