摘要
A feed device on a drilling and bolting turret retains anchoring bolts, before they are driven into a bore in a subterranean structure. A centering member is supported by the front part of the turret and comprises a cylindrical housing into which a circular support plate of a bolt is introduced. The shank of the bolt is introduced laterally through an aperture in the centering member. A clamping jack of the rotary and linear type, actuates a push-rod which, when it is located opposite the centering member, makes it possible to push the plate of the bolt to the bottom of the housing and retain it there.
