An automated road sweeper is provided including transport apparatus suitable to allow the sweeper to travel on a road surface including debris, a plurality of cleaning members arranged at fixed points located in different portions of the sweeper and suitable for cleaning within predetermined cleaning areas, and a selector operatively connected to the cleaning members, suitable for scanning the road surface and locating the debris so as to select and exclusively operate the cleaning members, the cleaning area of which covers the debris during the movement of the sweeper.

A landscaping blower nozzle assembly includes an inlet section for allowing air into the assembly, an elbow section and a motor. A nozzle is insertable into the elbow section such that the motor moves the elbow section in a moveable motion back and forth though at least 180 degree of motion for aiding the operator in the movement and removal of leaves and other debris. A breakaway coupler prevents damage to the blower nozzle when coming into contact with a rigid surface or structure. A tensioner assembly prevents distortion of the nozzle tip when subjected to high velocity air from the blower motor.

A blower including a housing at least partially defining a chamber, a motor including a drive shaft defining a rotational axis, and an impeller drive by the motor to generate an air flow in the chamber. The blower also includes a coupler operably connected between the drive shaft and the impeller to transmit torque therebetween, the coupler being connected to one of the drive shaft and the impeller and including a plurality of ribs configured to engage the other of the drive shaft and the impeller, each rib defining a rib axis transverse to the rotational axis, each rib axis being arranged tangent to a circle centered on the rotational axis.

A material collection system includes a conduit, a vacuum generator coupled to the conduit, an engine powering the vacuum generator, and a container mounted to a chassis of a vehicle. The vacuum generator generates airflow for drawing material into a material inlet of the conduit. The container receives collected material from the conduit. The material collection container can receive collected material from the conduit. The control system can include a load sensor and a controller in electrical communication with the load sensor. The load sensor can detect a load applied by the collected material received in the material collection container and transmit an output signal indicating the load applied by the collected material. The controller can determine a weight of the collected material received in the material collection container based on the output signal and determine an aggregate weight of the vehicle using the determined weight of the collected material.

A self-propelled sweeping machine, having a chassis comprising at least one driven drive axle with wheels, for cleaning drivable, preferably solid, ground surfaces such as roads, streets, paths and cycle paths, squares or the like, consists of a refuse collection container which is built onto the chassis for receiving refuse which is lifted from the ground surface by means of generated suction air and/or suction force of a suction air unit comprising a suction air blower, by a suction device provided at the front end of a suction air line, and which is supplied via the connected, preferably rising, suction air line to the interior of the refuse collection container, wherein the refuse collection container has a screening device which is arranged spaced apart from the upper container wall for separating the refuse and, for conducting the suction air, has a downstream air outlet line for the suction air to be discharged, and wherein for the emptying process the refuse collection container is configured at the rear end so as to be pivotable about a horizontal axis arranged transversely to the forward direction of movement, and for emptying refuse the inner face of the rear wall of the refuse collection container is configured as a sliding surface which rises, respectively is inclined, to the rear, wherein the suction air unit, which is line-connected by a suction air opening to the interior of the refuse collection container, is arranged on the outer face of the rear wall of the refuse collection container configured with an internal sliding surface.

A fan with airfoil blades is provided for a regenerative air vacuum street sweeper. The blades are formed using cut and pressed upper and lower panels which are welded at a forward edge to a rod to form the airfoil leading edge and welded at the rear edges to form the airfoil trailing edge. Pins extend laterally outwardly from the rod for mounting each blade in corresponding holes in the front and rear plates of the fan housing. The side edges of the blade are welded to the plates at a 9-11° angle of attack. The airfoil blades allow for reduced size, horse power, noise, and manufacturing and shipping costs.

The present invention relates to street sweeper. According to a first aspect of the invention, different mechanisms are disclosed for controlling the movement of the brush-holder arms in a horizontal plane, while also damping side and front impacts. According to a second aspect, a sweeper is disclosed, in which the movement of the brush-holder arms (3) in a vertical plane is imparted by a set of four profile members, arranged in two pairs which each forms a deformable parallelogram, wherein the deformation of the parallelogram is actuated by a jack (25) and the own weight of the sweeping arm. The jack is configured to remain below the upper profile members (11) of the two pairs when the brush-holder arm is raised to its maximum height. According to a third aspect, the suction turbine (103) is arranged in such a way that load losses are reduced during the operation of the sweeper.

A hand-held suction system includes: a hand-held suction device, a tube unit and a bag unit, wherein the tube unit has a suction tube and a tube connecting part, and wherein the bag unit has a collecting bag and a bag connecting part. The tube connecting part and the bag connecting part are designed to form a mechanical connection to one another in order to hold the bag unit by way of the tube unit. The tube connecting part is arranged in such a way on a circumference of the suction tube, in an upper half of the circumference in a circumferential direction, in a correct operating position of the suction system, and the suction system is designed in such a way that the bag unit held by the tube unit extends downwards in the circumferential direction along the suction tube, on the upper half of the circumference.

A debris-collecting apparatus includes a mobile frame, an input portion configured to receive incoming air and debris, and a bagging system having a porous bag and a dust skirt surrounding the porous bag.

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.
