The FODBot consists of a primary power source, a fan for creating suction, a suction nozzle for picking up FOD from flat areas and depressions in the flat areas, a horizontal brush for moving FOD to the suction nozzle and a cup brush with deformable linkage that can adjust to vertical surfaces and move FOD from the edge of these surfaces to the suction nozzle. The FOD removal machine also contains FOD sensors, position sensors and an algorithm and computer to create a digital twin of all acquired FOD by building a database of the FOD's type, location and time of cleaning.

A hydraulic driving device of a suction car includes a HST circuit, a suction actuator, a supply channel and a switching valve. In the HST circuit, a first connection channel and a second connection channel connect between a traveling drive pump and a traveling motor in a closed circuit. The suction actuator suction drives a suction device by being actuated by a hydraulic pressure. The switching valve allows oil discharged from the traveling drive pump to the first connection channel to be supplied to the traveling motor in a first operation state. The switching valve allows oil discharged from the traveling drive pump to the first connection channel to flow into the supply channel and be supplied to the suction actuator in a second operation state.

A multi-use garbage truck has an ability to not only to front load containers of garbage into a hopper in a refuse collection body, but also an ability to swap out the forks, if not arm connection assemblies, or even entire frame arms, to be replaced with one of a plurality of attachments which connect to at least one, if not both frame arms with attachments for various uses such as snow plow, leaf blower, street sweeper, bucket, grapple, etc. Furthermore, an ability to independently operate the left frame arm relative to the right frame arm can now be provided so that the left frame arm can utilize and perform one function and the right frame arm provide another or at least be independently operable from one another.

A rock cleaning device for dislodging and cleaning landscaping materials, such as landscape rock includes a vacuum assembly and a suction head. The vacuum assembly generates an airflow through a tube thereof. The suction head is engaged to the tube distal from the vacuum assembly so that an interior space, which is defined by the suction head, is in fluidic communication with the tube. The suction head has an opening positioned in a bottom thereof. A set of nozzles is coupled to a top of the suction head and is engageable a hose, which extends from a source of pressurized air. The nozzles direct pressurized air from the hose through the interior space to dislodge objects, such as landscape rock embedded in a surface, and to clean the objects that now are entrained in the airflow.

A vacuum and container assembly is provided for collecting and disposing of dog poop. The vacuum includes a housing with an inlet tube or nozzle. The container assembly includes an outer sleeve and an inner flexible, air permeable bag. The sleeve is open at the rear end so as to fit over the vacuum nozzle, with the bag residing in the nozzle. The front end of the container assembly is temporary closed by flexible fingers. When the vacuum is turned on, the dog poop is suctioned past the fingers into the bag, without touching the vacuum housing or nozzle. The container assembly can then be removed from the nozzle and deposited in a waste receptacle for disposal.

A street sweeper comprises a dirt container and a suction device. The suction device comprises a suction mouth, a suction channel and a suction fan. The suction fan generates a suction flow which leads into the dirt container. Furthermore, the street sweeper comprises a recycling system with a separating device. The separating device separates sucked-in dirty water from the dirt container into the recycling system. Furthermore, the street sweeper comprises a fresh-water tank in which fresh-water is stored. Furthermore, a cleaning device is provided by means of which at least a part of the recycling system can be cleaned. The fresh-water from the fresh-water tank is used for cleaning the recycling system.

A dust mitigation system for a mobile sweeper, the dust mitigation system including a cover to at least partially cover one or more brushes of the mobile sweeper, a dust collector including at least one fan and one or more filters, and at least one duct fluidly connecting the cover with the dust collector.

A backpack tool kit including a backpack assembly with a casing and a battery pack received in the casing; and at least one tool connected to the casing of the backpack assembly and electrically connected to the battery pack. The backpack tool apparatus can be provided with multiple tools to simultaneously realize different operations and functions. Moreover, the tools are configured to be detachably connected to the backpack assembly, and can be replaced with different tools to realize different operations and functions according to needs.

The invention proposes a single-engine, truck-mounted sweeper machine that incorporates systems and devices for an improved power pack mounting mechanism. A propeller shaft mounted at the side of the engine is used to take power from a driven pulley. At the rear end of the propeller shaft a suitable capacity power pack driving the sweeping system is attached. A clutch is introduced between the engine-driven pulley and the power pack, which may be coupled or decoupled as required instead of driving the power pack all the time. The power pack may be activated or deactivated for better component life and to conserve energy. In place of hydraulic pump an electric generator may be substituted. The overall advantage of the invention is that higher power could be provided for effective sweeping function in truck-mounted sweepers, without change in engine capacity or environmental concerns such as emissions.
