A blower apparatus is driven by a drive motor and has an intake opening and a discharge opening. The blower apparatus has a handle for guiding the blower apparatus with the handle being mounted on the blower apparatus such that it is pivotable from a first position into at least a second position. The blower apparatus is configured such that, during operation of the blower apparatus, an air flow passes through the discharge opening in a discharge direction. The handle has a grip region, which, in the first position, is inclined differently with respect to the discharge direction compared with the second position.

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 blowing-suction machine includes a casing, a suction duct arranged at the front portion of the casing. It further includes a motor and a shredder mechanism that are arranged in the casing in order from rear to front. The front end of the shredder mechanism is connected to the rear end of the suction duct. The shredder mechanism includes blades and a cutting assembly that are arranged in order from rear to front. The blades are arranged on an output shaft of the motor. The cutting assembly is arranged at a rear end of the suction duct for shredding fallen leaves. The cutter cooperates with the secondary cutter such that fallen leaves and rigid trashes can be effectively shredded by the blowing-suction machine. Fallen leaves can be effectively separated from air via the collecting cartridge and the filtering unit, such that the amount of the collected leaves is effectively increased.

The present invention is directed to a debris collection bag for a blowervac device that is carried on a user's back. This improves the user's mobility and allows an increased capacity for the collection bag. The bag's location provides a comfortable weight distribution by separating the weight of the blowervac from the weight of the collection bag. The bag has a dust dispersion system to direct dust away from the user. The bag has a closure located on the side which makes emptying the bag easier. The bag closure is provided to make opening and closing the bag easier and faster, and resistant to dust and debris.

A backpack tool kit including a backpack assembly with a casing and a battery pack received in the casing; and at least one tool connected to the casing of the backpack assembly and electrically connected to the battery pack. The backpack tool apparatus can be provided with multiple tools to simultaneously realize different operations and functions. Moreover, the tools are configured to be detachably connected to the backpack assembly, and can be replaced with different tools to realize different operations and functions according to needs.

A remote debris tank includes a housing having a top and a bottom discharge opening, a pair of discharge doors mounted to opposing lateral sides of the bottom discharge opening and configured for pivotal movement between an open position and a closed position, and an actuating shaft operably coupled to the first and second discharge doors. The remote debris tank also includes a crank lever having a plurality of vertices, where the crank lever is secured to the actuating shaft at a first vertex and configured to rotate with the actuating shaft. A first radial arm has a first end articulately connected to a second vertex of the crank lever and a second end articulately connected to the first discharge door. Similarly, a second radial arm is articulately connected to a third vertex of the crank lever and extending away from the actuating shaft to the second discharge door.

The present invention relates to a blowing-suction device, selectively operating in a blowing mode or a suction mode, comprising: a main body; a motor located inside the main body, the motor having a motor shaft providing rotational motion; a fan assembly driven by the motor to rotate; and a blowing assembly and a suction assembly connected to the main body; wherein the fan assembly includes an axial fan that, while in the blowing mode, the blowing assembly is connected to the main body, and wherein the axial fan rotates around a first rotary shaft, and, while in the suction mode, the suction assembly is connected to the main body.

The self-propelled high-performance shot-peening machine combined with a scarifying machine, for the treatment of coatings surfaces of bituminous conglomerate, asphalt, concrete or metal, is composed of a shot-peening unit (A-A), a suction, filtering, separation and storage unit (B-B), a scarifying unit (C-C) and a mechanic-magnetic unit (d-D) coupled together.

It comes typically to solve the problem of the removal of the new typologies of drop or lamellar road markings, with subsequent regeneration of the macro and micro roughness of the road coating,

subjecting the surface to be treated to two treatmentsintegrated milling and shot-peeningby a single pass, adapting itself to the road profile and guaranteeing to remove only the protruding part of the road markings, subsequently immediately regenerating the roughness and microroughness of said surface, noticeably reducing the critical factor of the working time, eliminating the possibility of error in the application of the treatment.

The basic principle consists in utilizing the six-drum scarifying machine 20, 20 only to remove the protruding parts without breaking into the road coating, the number of rollers of the drums 21, 22, 23, 24, 25, 26 and the rotation speed being automatically chosen by the programme to optimize results and working speed; same principle applies to the shot-peening, where the rotation speed and the quantity of abrasive can vary, aiming to the highest yield and speed, the whole managed by a system software implemented by an electric device like PLC, Tablet, Smartphone or Wi-Fi Server-Router.

It solves also the problem of the recycling of the grit by its overheating with sticking of the bituminous, gummy materials and others, performing their removal by a single pass and their final decontamination from the stuck bituminous materials C in a further subsequent sieve 7 with preliminary cooling by intercooler 7, 7, the avoid their deformation and ovalization for a correct recycling D, 1, 1 and reuse of the microspheres 1, 2, 2.

The technology has been applied to a road lorry with three to five axes, with the aim to have a vehicle allowed to free circulation on the roads to reach the possible yards, airports and so on and to be able to work in moving yards without closing the lane or the section where it is necessary to remove the road markings and remake them immediately after.

An autonomous self-propelled unit (D-D) with suction, storage and housing of the magnetic group completes the regeneration and cleaning action removing from the surface coating any grit possibly dispersed and not recovered by the shot-peeni
