A road debris collection assembly for includes a vehicle that has a storage tank thereon and an engine. A vacuum unit is coupled to the storage tank and the vacuum unit produces vacuum pressure within the storage tank when the vacuum unit is turned on. A pair of shredding units is each coupled to the vehicle and each of the shredding units has an inlet is aligned with a roadway upon which the vehicle is driving. Moreover, each of the shredding units is in fluid communication with the vacuum unit to suctionally collect debris from the roadway. Each of the shredding units has a plurality of blades therein and the blades in each of the shredding units shredding the debris when the shredding units are turned on.

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 material collection system and vehicle can have a gross vehicle weight rating of at or below approximately 26,000 lbs.

A guidance vehicle guides a dog for a walk, and includes a leash attachment, a distance sensor, and an electronic control unit. The leash attachment is configured to attach a leash that connects the dog. The distance sensor is configured to detect a dog-to-vehicle distance being a distance between the dog and the guidance vehicle. The electronic control unit is configured to execute a travel control of the guidance vehicle. The electronic control unit includes, as one of modes of the travel control, a walk guidance mode that causes the guidance vehicle to automatically travel along a walk route while guiding the dog to walk. The walk guidance mode executed by the electronic control unit includes a basic walk mode that controls the dog-to-vehicle distance so as to maintain a constant distance when the dog is moving along the walk route.

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.

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.

The present invention relates to a blowing-suction device. The blowing-suction device includes: a housing, having a first opening connected to the outside; an air tube, connected to the housing; an air flow generation apparatus that operably generates an air flow, where when the blowing-suction device is in the blowing mode, the air flow is blown out from the air tube, or when the blowing-suction device is in the suction mode, the air flow is sucked from the air tube; and a collection apparatus, configured to collect an object sucked by the blowing-suction device in the suction mode, where the collection apparatus is connected to the first opening both in the blowing mode and in the suction mode, and the collection apparatus further includes an air admission portion, and in the blowing mode, the air admission portion is open; or in the suction mode, the air admission portion is closed.

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 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.
