Apparatus for Laying and Anchoring a Sheet of Material on a Ground Surface

摘要

A machine (20) for laying a film (122) on a ground surface such as a landfill has a pair of opposed, support arms (84) each having a respective film roll support mechanism (94). In some embodiments the support arms are pivotable. Each film roll support mechanism (94) has a moveable arm (102) with a film roll support bracket (106), and a hydraulic system (98, 104) controllable by an operator of the machine for retracting and extending the moveable arm (102). The machine has means (120, 124) for holding the roll (96) of film between the brackets (106) for unwinding the film onto the ground. The machine may include a film cutter assembly (154) for cutting the laid film. The machine permits the controlled laying of the film and the operator adjustment of the position of the roll of film in response to windy conditions, obstacles and sloping ground.

主权项

1. A machine for laying a film on a ground surface and depositing an anchoring material on the film, comprising:
(a) a container for holding the anchoring material; (b) means for releasing the anchoring material from the container; (c) means for moving the machine over the ground surface; (d) a pair of support arms each having a respective film roll support mechanism operatively connected thereto, the support arms being movable between an operating position in which the respective film roll support mechanism is extended outward from the machine at a respective opposed side thereof, and a retracted position in which the respective film roll support mechanism is adjacent to the respective opposed side of the machine; (e) the two film roll support mechanisms each comprising:
(i) a movable arm;(ii) a film roll support bracket operatively connected to the movable arm; and(iii) a hydraulic system controllable by an operator of the machine for retracting and extending the movable arm to fix the film roll support bracket in a selected position above the ground surface; and (f) means for holding the roll of film between the two roll support brackets for unwinding of the film onto the ground surface as the machine is moved and the anchoring material is deposited onto the film.
