ABSTRACT:
A water scoop constructed for use in conjunction with the scoop bucket of a rubber tired self-powered mining vehicle for collection, transporting and discharging water. The disclosed water scoop is constructed to engage the discharge blade on the scoop bucket so that when it is to be used it can be drawn into the bucket. The water scoop is a generally closed vessel having a configuration to fit in the scoop bucket. Vents are provided in the top rear portion of the water scoop to allow trapped air to escape as the water scoop is filled. A relatively large gate is provided across the exposed end of the water scoop and it is positionable to allow the passage of water. The gate of the bucket can be operated by a hydraulic cylinder which is powered by the hydraulic power unit which operates the scoop discharge blade. During use with the water scoop drawn within the scoop bucket, the hydraulic attachments to the blade operating cylinders are disconnected and attached to the hydraulic gate cylinder. Baffles are provided internal in the water scoop vessel to prevent water surges when the mining vehicle changes direction or speed. The bucket, containing the water scoop, is positionable by an operator to be easily positioned in a pool of water which is to be drained.
