Plunger mixer device

Abstract

Disclosed is a plunger mixer device (307B, 309B, 311B, and 313B) deployable within a hollow shaft injection drill bit system (305B). The plunger mixer device (307B, 309B, 311B, and 313B) includes a motor (313B), a piston (507D), and a plunger motor assembly (403C, 405C, 407C, 409C, 411C, 413C, and 415C). The motor (313B) is connected to a feeder auger tip. The piston (507D) is configured to be driven by the motor (313B). The piston (507D) is connected to a feeder auger (103C, 105A, 109B, and 205A). The plunger motor assembly (403C, 405C, 407C, 409C, 411C, 413C, and 415C) includes a stacked series of panels (503D, 505D, and 507D), and a plurality of motor shafts (311D). The stacked series of panels (503D), 505D, and 507D) has a plurality of ribbed panels (307D) with a rib locking feature. One of the stacked series of the panel (507C) is actuated by the motor (313B). The ribbed panels (303C) lock between each other when the ribbed panels (305D, 307B, 307D, and 309B) are spun into a fully formed deployment. The ribbed panels (303C, 305C, and 307C), upon deployment, serve to mix wet and dry materials by subsurface hollow shaft drilling augers (103A) ascending in communication with a feeder auger ascent and the subsequent descent.
