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.

Disclosed is self-propelled equipment for street sweeping and/or weeding, where modifications were made to the cleaning system of the filters, the battery for driving the motors with electric start, front fairing assembly over the turbine, combustion or electric motor, debris suction pipe, hydraulic components, headlights, motor protection and brooms and motors for each front wheel and telescopic brooms that will act at a 180° angle by sweeping away debris from the sidewalk or even from the street ahead of the main brooms.

A backpack blower has a backpack with a load-bearing frame, a blower tube with a backpack-side tube section which is held on a rear side of the load-bearing frame, and a hand-side tube section which extends past a first side region of the load-bearing frame, a drive motor, an energy source for the drive motor, and an axial fan which is driven by the drive motor, has an axial fan axis, and is arranged in the backpack-side tube section of the blower tube. The backpack-side tube section of the blower tube runs with a main direction component in a backpack transverse direction of the load-bearing frame and has an axial blower tube end termination which projects laterally beyond a second side region of the load-bearing frame, which second side region faces away from the first side region, and/or is surrounded at least on a part of its circumference by a protective ring element which is connected to the load-bearing frame. The blower may be an electric leaf blower.

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.

The invention provides a blower. The blower includes: a main body extending in a longitudinal direction, a battery pack supporting member arranged on the main body, and a battery pack arranged on the battery pack supporting member, the battery pack supporting member is separable with respect to the main body, which includes a body forming a battery pack receiving portion and a mounting portion being coupled with the main body, the battery pack supporting member and the battery pack are detachably coupled to the main body. According to the blower of the invention, the battery pack supporting member is engaged with the main body, and a single battery pack or a dual battery packs can be installed by installing battery pack supporting members with different structures on the main body of the blower, which facilitates the switching between the single battery pack and the dual battery packs.

Disclosed herein are methods, compositions, and kits for high efficiency, site-specific genomic editing of cells for treating or preventing genetic blood disorders.

A system and method for efficient engine operation of a material collection system is provided. A material collection system can have a control system, a boom that supports a conduit, a power source, and a vacuum generator. Sensors can provide data on operation of the material collection system. The control system can adjust the vacuum generator power output based on sensor data to efficiently manage energy usage.

A debris management vehicle is disclosed that has a vehicle frame and a fan assembly coupled to the vehicle frame. The fan assembly has a rotor axis oriented obliquely to a horizontal plane. A nozzle defines a nozzle inlet and a nozzle outlet. The nozzle inlet is in fluid communication with an outlet of the fan assembly. The nozzle outlet is rotatable about a nozzle axis that is orthogonal to the horizontal plane.

A handheld work apparatus has a blower wheel. The blower wheel is held via a nut on the shaft in a manner locked against rotation by frictional force. A thread moment of friction is transmittable between the nut and the shaft via a thread section. A first moment of friction is transmittable between the nut and the blower wheel via a first friction contact surface. The first friction contact surface is configured such that, at a minimum tightening torque of the nut, the first moment of friction is greater than the thread moment of friction. As a result, during the operation of the work apparatus when there is a relative movement between the blower wheel and the shaft, the blower wheel moves the nut along therewith. The nut retensions the blower wheel against the shaft. The second friction contact surface runs conically with respect to the rotational axis.
