Problems solved by technology

This causes the suction port to reject internal airflow while it is receiving air from the atmosphere and material is subsequently left behind which is highly undesirable.

Embodiment Construction

[0025]Reference will now be made to FIGS. 1 through 8, which show a preferred embodiment of the dustless pick-up head system of the present invention, as indicated by general reference numeral 100. The dustless pick-up head system 100 is for use with a surface cleaning vehicle 102 for removing dust (including fine particulate matter) and debris (including bottles, cans, leaves, dirt, and so on) from a surface to be cleaned 104.

[0026]The preferred embodiment dustless pick-up head system 100 is for use with a surface cleaning vehicle 102 for cleaning a surface to be cleaned 104 and basically comprises a housing 110, substantially rigid skirt 108, a debris outlet 120, debris passage 130, and a substantially sealed continuous-debris passing door apparatus 150 operatively mounted on the housing 110. The dustless pick-up head system 100, particularly the housing 110, define a generally central fore-aft longitudinal axis “L”.

[0027]More specifically, the dustless pick-up head system 100 com...

Abstract

A pick-up head system for use with a surface cleaning vehicle comprises a housing having a suctioning bottom opening open in fluid communication and debris transfer relation to the interior. A debris receiving main inlet is disposed in the front wall of the housing, in debris transfer relation for receiving debris to the housing. A substantially sealed continuous-debris-passing door apparatus is operatively mounted on the housing at the debris receiving main inlet in vertically movable relation for movement between a substantially sealed surface engaging position whereat the substantially sealed continuous-debris-passing door apparatus extends upwardly from the level of the bottom peripheral edge of the housing, and a raised position whereat the substantially sealed continuous-debris-passing door apparatus is raised above the substantially sealed surface engaging position; and a debris outlet in the housing open in fluid communication and debris transfer relation to the substantially hollow interior of the housing.

Description

RELATED APPLICATIONS[0001]This application is a non-provisional application claiming priority from U.S. Provisional Patent Application Ser. No. 61 / 496,410 filed on Jun. 13, 2011, which is herein incorporated by reference.FIELD OF THE INVENTION[0002]The present invention relates to surface cleaning vehicles, and more particularly to dustless pick-up head systems for surface cleaning vehiclesBACKGROUND OF THE INVENTION[0003]Prior art pick-up heads do not completely seal to the ground in a manner which allows material to readily enter the front of the pick-up head. Material enters the pick-up head by way of pushing back the pliable front flap that runs along the front, or by way of an opening to permit passage of debris into the housing. This readily presents the opportunity for dust and other fine particulate matter to escape from the housing.[0004]Furthermore, the pliable front flaps on conventional pick-up heads allow for a temporary loss of suction power within the width of the pic...
