Abstract
An apparatus for injecting slurry in a field has a wheeled slurry tank, a feed conduit communicating with the interior of the tank, a transverse manifold to receive slurry from the feed conduit, several slurry injector pipes spaced along the conduit, and either a slurry pump or air pressurizing means for moving slurry from the tank under pressure for discharge through the feed conduit, the manifold, and the injector pipes. In all the slurry injector pipes are identical flow controlling and equalizing elements which have a single orifice and which are formed of elastomeric material which can flex to facilitate passing solid debris through the orifice. The orifice size provides a positive pressure head in the manifold so all the pipes deliver substantially equal quantities of slurry per unit time under varying conditions of operation.
