Abstract
A vibrating device for a screed head assembly mountable to a screeding device includes a vibrating member and a vibrating system. The vibrating member comprises an integrally formed elongated member having upper and lower screeding surfaces and a vertical portion extending therebetween. The vertical portion may define a hollow cavity therealong. The vibrating system is operable to vibrate the vibrating member to compact and smooth the concrete surface. The vibrating system is mounted to the vertical portion of the vibrating member and operates to vibrate the vibrating member to screed the concrete surface when the lower screeding surface engages the concrete surface. The vibrating system may include a drive motor operable to rotatably drive at least one drive pulley which, in turn, drives a drive belt to rotate at least one eccentric element rotatably mounted to the vibrating member.
