Abstract
The present disclosure is directed to a continuous concrete proportioning plant of the mobile type movable from job site to job site not requiring extensive site preparation. The primary frame has a compact combination of cement sand and aggregate systems which permits sand and aggregate trucks to be backed onto a three sided hopper for each material which when charged is lifted and tilted toward the center of the machine where it feeds a belt conveyor running longitudinally toward the front of the machine. Each belt system contains a continuous belt weighing device and a totalizer will stop and/or clear the conveyor when a predetermined amount is attained. The sand and aggregate hoppers may be tilted to achieve the best flow rate through metering gates.
Claims5
A mobile concrete proportioning plant comprising an elongated primary frame having retractable transport wheels at one end and a towing fifth wheel at the other end, cement silo means proximate the rear of said primary frame extending transversely thereof and dischargable substantially centrally thereof, a sand belt conveyor system along one side of said primary frame, an aggregate belt conveyor system along the other side of said primary frame, a three sided telescopic aggregate hopper pivoted to said main frame adjacent the aggregate belt conveyor having means for tilting said hopper to discharge aggregate onto said conveyor, a three sided telescopic sand hopper pivoted to said main frame adjacent said sand belt conveyor having means for tilting said hopper to discharge sand onto said sand belt conveyor, collecting hopper means proximate the front of said primary frame positioned to receive cement from said silo means and sand and aggregate from their respective conveyor belts for collecting and discharge upon a concrete distributor, and means connected between said pivoted telescopic sand and aggregate hoppers for maintaining them in the fully raised rigged in condition for over the highway transport.
