A collection device for debris and animal waste is an apparatus that optimizes airflow to effectively and safely collect debris, preferably pet waste. The apparatus includes a canister, at least one handle assembly, an airflow inlet nozzle, a portable power source, and a fan assembly. The canister houses collected debris and the fan assembly. The at least one handle assembly, the airflow inlet nozzle, and the portable power source are mounted with the canister. The at least one handle assembly allows a user to easily maneuver the canister and the airflow inlet nozzle. The fan assembly suctions debris into a debris chamber of the canister through the airflow inlet nozzle. The portable power source provides the necessary power for the fan assembly to operate. The apparatus further includes an air-permeable collection bag that is housed within the debris chamber to facilitate the removal of collected pet waste within the canister.

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 single-tube blowing suction device, including a body, an airflow generation apparatus, a collection apparatus, and a blowing-suction tube. The airflow generation apparatus has an air inlet portion and an air outlet portion and is rotatably mounted on the body. The airflow generation apparatus rotates relative to the body to enable the single-tube blowing suction device to switch between a suction mode and a blowing mode. In the suction mode, the air inlet portion of the airflow generation apparatus is in fluid communication with a first end of the blowing-suction tube, and the air outlet portion is in fluid communication with a connection port of the collection apparatus. In the blowing mode, the air outlet portion is in fluid communication with the first end of the blowing-suction tube. In the single-tube blowing suction device of the present invention, one tube is used for both blowing and suction.

A system and method for disabling the travel of a vacuum truck is provided in which a vacuum boom initiates an interlock signal when positioned back into a travel cradle. An additional positional tank bed further includes an interlock signal when the bed is in a secured in a travel position. The vacuum truck is prevented from having its brakes released or prevented from being put into a travel gear if either the truck bed or vacuum boom are not in secure travel positions. The present system and method utilize pneumatic operating signals available from the vehicles power take off and blower mode switch.

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 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.

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.
