FIELD: road-building equipment, particularly vibratory plates for tamping gravel-stone materials, loose ground, asphalt and similar materials.
SUBSTANCE: vibratory plate has vibrator with vibration source assembled on shaft. Gravity center of shaft is offset in radial direction relative rotation axis. Vibratory plate has drive motor connected to vibrator by belt transmission through pulleys fixed to vibrator and motor shafts. Distance from rotation axis of vibrator pulleys to inner generator of working pulley surface varies in radial direction relative pulleys rotation axes, which coincide with rotation axis of vibrator shaft.
EFFECT: improved operational characteristics due to providing constant tightening of transmission belt when relative position of vibrator and motor varies during vibratory plate operation.
