Benefits of technology

The patent is about a device that prevents dust and debris from flying off a work machine's auger unit. The device has a frame that surrounds the auger unit and a curtain that can be opened and closed to control the machine's operation. The curtain is made up of two layers of fabric that are guided along their edges by guide members. The device helps to keep the worksite clean and safe for the operator.

Problems solved by technology

However, when the dust curtain is in the open position, machine sensors mounted in proximity to the dust curtain located at the rear end of the machine, are obstructed due to the pivotal lifting of the dust curtain.
However, the '232 patent does not describe any sliding type curtain assembly that can be selectively opened during operation or positioning of the earth drilling equipment.

Embodiment Construction

[0012]Reference will now be made in detail to specific aspects or features, examples of which are illustrated in the accompanying drawings. Wherever possible, corresponding or similar reference numbers will be used throughout the drawings to refer to the same or corresponding parts.

[0013]FIG. 1 illustrates a side elevation view of an exemplary work machine 100 embodied as a blast hole drill machine herein. The work machine 100 includes a chassis 102 supported on a transport mechanism, such as, crawler tracks 104 as illustrated in the accompanying figures. The work machine 100 further includes a mast 106 mounted on the chassis 102 and supported about a pivot 108. During a drilling operation, the work machine 100 is supported on jacks 110. The work machine 100 uses long straight sections of drill pipes 112 which are connected to a work head 114, to operate a work tool 116 and perform the drilling operation. The work tool 116 may be a drill bit or a bore bit. The work head 114 may be a...

Abstract

A dust containment assembly for a work machine includes a frame having an access opening. The dust containment assembly includes a curtain assembly having a first curtain member a second curtain member. The curtain assembly further includes a curtain track assembly including at least one reciprocating cylinder assembly and first and second guide members. The first guide member is attached to one of a first edge of the first curtain member and a first side edge of the second curtain member. The second guide member is attached to one of a second edge of the first curtain member and a second side edge of the second curtain member. The second curtain member is movable between a first closed position and a second open position along the first curtain member through the first and second guide members.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a curtain assembly for a work machine, and more particularly to a dust curtain for a drilling machine.BACKGROUND[0002]In machines such as a rotary drilling machine, once a drilling operation is completed, the machine moves to a new location. An area around a hole drilled by the machine is covered on all four sides, of which three sides are enclosed by portions of a frame of the machine and the fourth side is selectively enclosed by a dust curtain of the machine which is located at a rear end of the machine. The dust curtain is moveable, and can be raised during movement of the machine, so that heaps of the drilled material surrounding the hole does not fall back into the hole, as the machine moves past the hole.[0003]The dust curtains are generally provided with a hinge joint at a top of the dust curtain, such that the dust curtain can pivotally flap open and lift by a certain height. This lifting operation is performed by hydra...
