摘要： A floor cleaning machine with dust control apparatus can assist in capturing dust created as a by-product during normal operations. The dust control apparatus is particularly applicable to propane-powered burnishers that use rotating pads to remove built up wax from hard surface floors. A floating scoop is attached to a floating hoop assembly to direct dust away from the rotating pad. The scoop is located tangentially to the housing that surrounds the rotating pad. An inlet to the housing facilitates airflow through the housing to pick up dust, which exits through the scoop. A containment canister with removable filter is in communication with the scoop. The air and entrained particulate (dust) swirls around the filter in a circular flow path to help separate the particulate from the air. The filtered air exits the canister and returns to the atmosphere.
摘要翻译：具有灰尘控制装置的地板清洁机可以帮助捕获在正常操作期间作为副产品产生的灰尘。灰尘控制装置特别适用于使用旋转垫以从硬表面地板上去除积聚的蜡的丙烷驱动的抛光机。浮动勺附接到浮箍组件以将灰尘远离旋转垫。勺子与围绕旋转垫的壳体相切地定位。壳体的入口促进通过壳体的气流以吸收通过勺子离开的灰尘。带有可移动过滤器的容纳罐与勺子通信。空气和夹带的颗粒（灰尘）以循环流动路径围绕过滤器旋转，以帮助将颗粒与空气分离。过滤的空气离开罐并返回大气。

摘要： Floor polishing machines include a motor housing, mounted vertically above the base of the machine that contains and protects the motor of the machine. A drip cover that may have a convex shape is mounted on the top of the motor housing and offset from the housing to provide a space between the housing and the cover through which air can flow to cool the motor during operation of the polishing machine. The drip cover has a cylindrical skirt that extends axially from the drip cover to surround the upper portion of the motor housing. Formed concentrically with the skirt, on the inner surface of the drip cover is a cup sized to accept, hold and protect the upper bearing of the motor. The drip cover further includes a downwardly facing electrical inlet or plug attached to the inner surface of the cover within the cylindrical skirt.
摘要翻译：地板抛光机包括一个电机外壳，垂直安装在机器的底座上方，用于容纳和保护机器的电机。可以具有凸形形状的滴水盖安装在电动机壳体的顶部并从壳体偏移以在壳体和盖之间提供空间，在抛光机器的操作期间空气可通过该空间冷却电机。滴水盖具有圆筒形裙部，其从滴水盖轴向延伸以包围电动机壳体的上部。与裙子同心地形成，在滴水盖的内表面上是一个尺寸适于接受，保持和保护电动机的上轴承的杯子。滴水盖还包括附接到圆筒形裙部内的盖的内表面的向下的电气入口或插头。

摘要： A floor surface treatment apparatus having a wheeled vehicle including a support for a floor surface treatment unit, the support being moveable relative to the vehicle. A floor surface treatment unit is pivotally carried by the support for swinging movement relative thereto. The support is configured to raise and lower the unit relative to the floor surface, upon movement of the support relative to the vehicle, through a range of working positions in which the unit maintains a generally vertical orientation relative to the floor surface and is generally in contact therewith and a servicing position in which the unit is swung up relative to the vehicle above the floor surface to a position in which the unit is generally angled relative to the floor surface.

摘要： An extraction machine for cleaning a floor surface, such as carpeting, has a cleaning solution dispenser capable of dispensing a chemical cleaning agent onto the floor surface, and a source of chemical cleaning agent carried onboard the extraction machine and defining an interior space for holding chemical cleaning agent. The container has an opening and a closure for the opening, with the closure having a passage extending therethrough in fluid communication with the interior space of the container. A chemical delivery line provides fluid communication between the passage and the cleaning solution dispenser for delivering chemical cleaning agent from the container to the cleaning solution dispenser. A metering device is disposed generally adjacent the container closure in fluid communication with the passage for metering the flow of chemical cleaning agent from the source of cleaning agent.
