FIELD: agricultural mechanical engineering. SUBSTANCE: invention specifically refers to bed equipment for accelerated tests of cultivating working tools of agricultural and reclaiming machines. Proposed bed includes frame, soil trough kinematically coupled to drive, bracket for attachment of tested working tools, gear for levelling and compaction of soil. Soil trough is manufactured in the form of corrugated cylinder with wide base and vertical wall. Trough is equipped with drive in the form of cog gear. Circular tires with rollers arranged between them are located on outer vertical wall of corrugated trough. Pair of driving sprockets of cog gear is mounted on vertical shafts in diametrical plane of soil trough. The latter is provided with framework and is installed between pairs of radial supports spaced diametrically and horizontal supports equidistant from each other positioned under base of soil trough. Bracket mounted over diameter of bearing trough intended for attachment of tested working tools presents U-shaped beam and is fitted with grippers carrying tested working tool for displacement along beam and with gear for levelling and compaction of soil. EFFECT: enhanced functional efficiency of bed. 9 cl, 6 dwg |
