Definitions

• lf is another object of the present invention to provide a pick-up head for use with a sidewalk sweeper or a factory floor sweeper, wherein dust, dirt and debris are directed to a debris receiving opening.
• a novel debris-plowing pick-up head for a mobile sweeper.
• the pick-up head comprises a housing defining a substantially hollow interior and having a front, a back, a left end and a right end, a top and a bottom, and a suctioning bottom opening for suctioning dust and small debris into the substantially hollow interior of the housing.
• a suctioning front opening is disposed in the front of the housing for receiving debris into the substantially hollow interior of the housing, in debris receiving relation with respect to a surface being cleaned.
• a selectively openable and closable door means operatively mounted on the pick-up head for selectively opening and closing the suctioning front opening.
• a dust and debris outlet in the housing for permitting dust and debris to be suctioned from the substantially hollow interior of the housing into a hopper.
• the housing 30 is tapered from a higher central portion 31 to a lower outer left portion 311 and a lower outer right portion 31r. Tapering the housing 30 in ihis manner permits sufficient air flow at the left and right ends 34,35 respectively, of the housing 30 to bo sufficient enough to suction dust and debris from the left and right ends 34,35 of the housing 30.
• the means for urging debris towards die suctioning front opening comprises a second debris transfer belt member 42 operatively mounted on the housing 30 to the left of the suctioning front opening 60 by means of a second pair of rollers 44.
• the means for urging debris towards the suctioning front opening further comprises a second motor means 46 for selectively moving the debris transfer belt 42, and thereby moving debris towards the suctioning front opening 60.
• a portion of the air from the fan 324 is bled off to the atmosphere, as controlled by flap valve 390, either through the panel filter 382, as is shown m Figure 5, or through the direct opening 384, as is shown itt figure 6 .
• a large gate valve 392 is mounted in hinged relation at the junction betwt-en the panel filter 382 and a direct opening 384 for movement between a first position, as shown in Figure 5, whereat all of the air flow that is bled off is directed through the panel filter 382
• the large gate valve 392 seals against the slanted wall 394 in order to preclude air from escaping through the direct opening 384 This mode is used during dry sweeping in order to preclude dust from escaping to the atmosphere Circulation of only a substantial portion of the airflow significantly reduces the volume of air that must be filtered per unit time, which is a significant problem with vacuum type sweepers
