FLUID SPOKE INJECTOR SYSTEM

摘要

Disclosed herein is a device for introducing a fluid beneath the surface of the ground to ensure maximum utilization of such fluid especially in the growing of plants. The device comprises a rotating wheel assembly pivotally mounted by a shank to a tool-bar or implement through a side torque resistant mounting. The resistance to pivoting is controlled by a tension spring between the pivotable shank and the tool-bar mounting. Clamped to the lower end of the shank is an axle shaft upon which is mounted for rotation the wheel assembly. The wheel assembly includes a hub assembly formed of two identical hub portions and a hub sleeve which mounts injector spokes. The two hub portions have spokes which are integral with a circular rim which supports the injector spokes. The fluid is fed at low pressure into one end of the axle shaft through a flexible conduit. The fluid passes through a channel in the axle shaft and is then metered by a split sleeve distributor fixed to the axle shaft which functions as a valve when the wheel assembly rotates. The split sleeve distributor is so positioned as to permit a metered quantity of fluid only to the hub sleeve mounted spoke that has penetrated the soil. The injector spokes which penetrate the ground by means of a hardened pointed offset end, protect the outflow orifice from plugging. A countersink given to the outflow orifice also assists in preventing plugging of the orifice.
