DETAILED DESCRIPTION

(7) In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments or examples. These embodiments may be combined, other embodiments may be utilized, and structural, logical, and procedural changes may be made without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.

(8) As disclosed in FIG. 1, an embodiment of a counter-rotational whip head includes at least two bolts 101 that secure a stationary upper receiver 102 to a stationary lower receiver 107. Straddling a rotating upper whip mount 105 are a seal 103 and a radial bearing 106 that allow the upper whip mount 105 to rotate under the power transferred by a hydraulically-powered gearbox 118 to a plurality of rotating drive stand-off rods 119 that are operably connected to the upper whip mount 105 by a plurality of bolts 104. Flails 131 are attachable to the upper whip mount 105 via a plurality of adapter clevis's 134. The flails 131 are secured to the adapter clevis's 134 by a plurality of nuts 132 and bolts 133.

(9) The plurality of rotating drive stand-off rods 119 are further secured to an upper drive plate 120 with a plurality of bolts 121. A plurality of fragmentation collars 117 may be secured to the stand-off rods 119. The combined structure of these components serve to stabilize and unify the rotating middle section 502 of the whip head 501. When the plurality of fragmentation collars 117 are secured between the upper whip mount 107 and the upper drive plate 120 by stacking the fragmentation collars 117 over the stand-off rods 119, they comprise a rotating perimeter of the middle assembly.

(10) A plurality of bolts 104a also connect the stationary lower receiver 107 to the housing of the hydraulically-powered gearbox 118 via a plurality of shorter length stand-off rods 110. Pressurized hydraulic fluid is transferred into and out of the hydraulic motor 114, through a hydraulic fluid conduit system comprising a plurality of hydraulic flush fittings 108, which are connectable to a pressurized hydraulic fluid source, a plurality of hydraulic adapters 109, a plurality of upper elbow fittings 111, a plurality of hydraulic pipes 112, and a plurality of lower elbow fittings 113. The lower elbow fittings 113 are, in turn, directly connected to the hydraulic motor 114. The hydraulic motor 114 is secured to the gearbox case 200 with a plurality of bolts 115 and lock washers 116. The hydraulic motor 114, when put in rotational movement by the flow of the pressurized hydraulic fluid, transfers a rotational force to an encased gearbox 118 200. The bolts 104a, radial bearing 106, stationary lower receiver 107, hydraulic flush fittings 108, hydraulic adapters 109, shorter length stand-off rods 110, upper elbow fittings 111, hydraulic pipes 112, lower elbow fittings 113, hydraulic motor 114, bolts 115 and lock washers 116, and encased gearbox 118 comprise a stationary, middle assembly.

(11) As disclosed in Hg. 2, the encased gearbox 200 includes a set of beveled gears 201 202 configured in separate horizontal planes that are operably connected to each other by a plurality of pinion gears 203 that rotate around a horizontal axis. Engaging the hydraulic motor causes the upper bevel gear 201 to rotate on its vertical axis, which in turn causes the pinion gears 203 to rotate about a horizontal axis about 90 degrees from the vertical axis of the motor 114 and gearbox 200. When the upper beveled gear 201 is put in rotational movement by the hydraulic motor 114, the pinion gears 203, being operably engaged with both the upper 201 and lower 202 beveled gear sets, transfers an opposite-direction rotational force and movement to the lower beveled 202 gear set. The upper beveled gear set 201 drives an inner solid shaft 204 that drives the lower whip mount 125. The lower beveled gear set 202, being in opposite rotational direction to the upper beveled gear 201, drives an outer hollow shaft 205 that drives the rotational perimeter of the middle assembly 502 and the upper whip mount 105 in a rotational direction opposite the lower whip mount 125.

(12) By way of non-limiting example only, if pressurized hydraulic fluid is introduced into the hydraulic motor 114 so that the motor 114 rotates in a counter-clockwise direction, that rotational movement is directly transferred to the upper beveled gear 201 and the inner solid shaft 204 that ultimately drives the lower whip mount 125 in the same counter-clockwise direction. Accordingly, the upper beveled gear 201, being engaged with the pinion gears 203, causes the lower beveled gear 202 and outer hollow shaft 205 to rotate in a clockwise direction. The upper drive plate 120 is connected to a keyless coupler 122 that in turn is operably connected to the outer hollow shaft 205. Thus, as the outer hollow shaft 205 rotates in a clockwise direction, that rotational movement is transferred from the keyless coupler 122 to the upper drive plate 120 and the rotating drive stand-off rods 119 to rotate the perimeter of the middle assembly 502 and upper whip mount 105 in the same clockwise direction. The seal 103, bolts, 104, upper whip mount 105, stand-off rods 119, upper drive plate 120, bolts 121, and keyless coupler 122 comprise an upper whip mount assembly.

(13) Positioned between the rotating upper drive plate 120 and the lower whip mount 125 are a hub for a taper-lock bushing 123, and a 1-inch taper lock bushing 124 that are configured to allow the lower whip mount 125 to rotate in the same direction as the inner shaft. The lower whip mount 125 is connected to a whip mount cover 128 with a plurality of pinions 126 and bolts 130. A plurality of flails 131a may be secured between the lower whip mount 125 and the whip mount cover 128 with a plurality of nuts 127 and bolts 129. The taper-lock bushing hub 123, 1-inch taper lock bushing 124, lower whip mount 125, pinions 126 and bolts 130, nuts 127 and bolts 129, and whip mount cover 128 comprise a lower whip mount assembly.

(14) FIG. 3 discloses the major components of the counter-rotational whip head, including the upper receiver 301, the upper whip mount 302, and the clevis assembly 303, including its nuts and bolts 304 for attaching the flails 131 to the upper whip mount 302. FIG. 3 further discloses the shorter length stand-off rods 305, the rotating drive stand-off rods 306, the upper drive plate 307, and the combined lower whip mount 308 and whip mount cover 309.

(15) FIG. 4 discloses an embodiment that includes a middle assembly comprising a plurality of saw-toothed, fragmentation collars 117 401. In this embodiment, the saw-toothed fragmentation collars 117 401 are stacked between the upper drive plate 120 307 and the upper whip mount 105. 302 and include a plurality of holes 135 that correspond to the number and spacing of each rotating drive stand-off rod 119 306. The fragmentation collars 117 401 are stacked, one on top of the other, by passing the holes in the collars 135 over the rotating drive stand-off rods 119 306 until the collars 117 401 are stacked securely between the upper drive plate 120. 307 and the upper whip mount 105 302. In such an embodiment, the saw-toothed fragmentation collars 117 401, which are rotating in the same direction and speed as the upper whip mount 105 302, provide an increased fragmentation surface that may be applied against the solidified material along with the flails 131 131a.

(16) FIG. 5 discloses a completely assembled counter-rotational dual whip-head embodiment 501 that includes saw-toothed, fragmentation collars 502 chain link flails 503 on both upper and lower whip mounts.
