摘要： Robotic systems and methods for collecting trash are provided. The robotic system includes a vehicle, a camera, a trash collection unit, an actuator, and a controller. The vehicle includes a drive. The camera moves with the vehicle to capture images of the trash while the vehicle moves along ground. The trash collection unit is carried by the vehicle to collect the trash. The trash collection unit includes a vacuum pump and a collection conduit. The actuator is operatively coupled to the collection conduit to adjust a position of the collection conduit relative to the vehicle to position the collection conduit adjacent to the trash to collect the trash. The controller is coupled to the drive, the camera, the trash collection unit, and the actuator to coordinate movement of the vehicle, positioning of the collection conduit, and operation of the vacuum pump to collect the trash.

摘要： The present disclosure provides a material collection system. The 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 conduit, vacuum generator, the engine, and the container are supported on a hook-lift frame.

摘要： 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.

摘要： 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.

摘要： A pet waste collection device for collecting and discarding animal waste is provided. The device comprises a shaft with a vacuum head mounted to the shaft. A vacuum motor is mounted within the vacuum head. A nozzle is connected to the shaft and the vacuum motor provides a suction to the second end of the nozzle. A retractable claw member having a plurality of extendable claw fingers extends from the nozzle. A waste bag is positioned within the claw member. An access port is formed in the vacuum handle. Upon collection of the pet waste in the waste bag, the claw fingers close as the claw member retracts into the nozzle, the open end of the waste bag closing shut. The bagged pet waste is suctioned by the vacuum motor through the shaft to a waste bag receptacle within the vacuum handle and removable from the receptacle through the access port.

摘要： The present invention relates to a road sweeping apparatus with a disposable bag mounted, and more particularly, to a road sweeping apparatus driving at a low speed corresponding to that of walking of a worker to more conveniently collect all kinds of wastes scattered on a road in an automatic or manual manner, in which a bag into which the collected wastes are put is installed inside a loading unit and simultaneously the bag is easily slidably withdrawn toward one side of the loading unit to easily collect the bag. In addition, fuel consumption is reduced by a motor-driven manner through a battery and simultaneously exhaust gas including carbon is not generated to be quite eco-friendly.
