The invention provides a pit pump having a submersible hydraulic drive motor, a pump, and a bearing block assembly. The pump has a body, a fluid inlet in the body, a fluid outlet in the body, and an impeller operatively positioned in the body, whereby fluid can be pumped between the fluid inlet and the fluid outlet. The bearing block assembly operatively connects the hydraulic drive motor to the impeller of the pump, whereby the submersible hydraulic drive motor is spaced apart from the pump. The bearing block assembly preferably includes a housing and a drive shaft operatively positioned for rotational movement within the housing, whereby rotational movement can be transferred from the hydraulic drive motor to the impeller of the pump. The bearing block assembly preferably has at least one grease nipple and at least one bleeder nipple for maintaining grease lubrication within the bearing block assembly. Furthermore, the bearing block assembly is preferably lubricated with an extreme-pressure, water-resistant, and high-temperature grease.

A padding apparatus for padding underground cable or pipeline is provided. The padding apparatus is adapted to continuously separate excavated material piled alongside an excavated ditch into relatively fine padding material and relatively rough residual material as the apparatus moves forward. The padding apparatus continuously places the relatively fine padding material in the ditch. According to the invention, the apparatus includes a frame for supporting and moving an endless openwork in an endless path for lifting excavated material in an elevating direction. The endless openwork has rods and transverse chain sections attached to the rods, whereby the rods and chain sections define openings that allow relatively fine padding material to pass therethrough. A discharge conveyor is positioned beneath at least a portion of the endless openwork of the separator to receive the relatively fine padding material and convey the padding material to the ditch for padding cable or pipeline therein.

An improved padding machine is provided with a shaker assembly that vigorously shakes a moving openwork at a high frequency. The shaker assembly includes resilient mounts for attaching the shaker assembly to the frame of the padding machine, preferably adjacent the supports for an upper portion of the screening belt, which slides across the top of such supports. The rubber or rubber-like resilient mounts support an eccentric shaft that is journalled in associated bearings for rotation beneath an upper portion of the screening belt. The eccentric shaft preferably extends substantially the entire width of the screening belt to either side of the padding machine. A motor is connected to a drive end of the eccentric shaft for rotating the shaft. When the motor rapidly rotates the eccentric shaft, the off-center body of the eccentric shaft causes vibration, which is translated through the resilient mounts to the frame of the padding machine adjacent the supports for the screening belt. Thus, high frequency vibratory motion is imparted to the moving screening belt.

An improved pipeline paddling apparatus includes a separator for separating fine material out of spoil which is piled along side an excavation, an elevator for transporting spoil to the separator, a pair of guide projections for guiding spoil into the elevator and a pair of auger type devices for directing spoil from the guiding projection both toward the elevator and in the elevating direction. A conveyor is provided to transport the separated fine portion of the spoil back into the excavation, thereby padding the pipeline. The elevator, guide and augers are pivotally adjustable as a unit with respect to a tracked vehicle, which provides maximum adjustability. In a second embodiment for use in rocky soil, the auger-type devices are eliminated and the guide projections are given a broader, concave inner guide surface.
