Definitions

  • the invention as expressed in the title of the present specification, relates to a blowing accessory equipment for a sweeper or similar street cleaning machine, providing advantages and characteristics, which are described in detail below, which are an improvement in the current state of the art.
  • the object of the present invention is an air blowing accessory that, made up of a set of elements that, at least, comprises a flexible air-conducting tube with a water-conducting tube and a control handle, defines equipment especially designed for its secure incorporation or removably attached to a sweeping or similar street cleaning machine and using the air expelled by the sweeper or cleaning equipment itself to channel it, through the flexible tube, and use of this air by an operator located next to the machine to blow the waste and direct it towards the suction or transport opening, thereby avoiding the use of the traditional portable blower.
  • the field of application of the present invention falls within the sector of the industry dedicated to the manufacture of machines, apparatus, devices and equipment for street cleaning, focusing particularly on the field of those intended for cleaning by applying air.
  • These particles have various emission sources.
  • One of these emission sources is generated when the particles deposited in the soil are removed; when the particles are stirred up, the dust generated contains high proportions of fine dust particles, called PM2.5 and PM10.
  • the sprayers or nebulizers of said water are located close to the generation and transport of the air that contains these particles.
  • blowers lack any fine dust collection system, which means they generate a high amount of PM2.5 and PM10 particles, which are toxic to passers-by and to the operators who operate the blower.
  • the operator of the blower must carry a backpack that bears the weight of the engine and fuel tank (in the case of blowers with a heat engine) or the batteries and electric motor (in the case of electric blowers). In both cases, the weight and noise borne by the operator are considerable.
  • Sweepers, and cleaning machines in general have an integrated water tank, to be able to use them to collect fine dust.
  • sweepers in general and vacuum sweepers in particular also have a turbine to generate suction air by creating a vacuum; this air helps to suck up waste, including fine dust carrying PM2.5 and PM10, and place this waste in the storage hopper.
  • the objective of the present invention is, therefore, to provide a practical solution to the aforementioned problems by developing a blowing accessory equipment that can be incorporated into the sweeping or street cleaning machine itself and use the air expelled thereby to channel it and that can be used by an operator to blow the waste and direct it towards the suction or transport opening, avoiding the use of the traditional portable blower.
  • blowing accessory equipment for a sweeper or similar street cleaning machine that the invention proposes is configured as an optimal solution to the aforementioned objectives which, in turn, represents an improvement of the current state of the art, the characterising details being that which make it possible and that distinguish it, conveniently contained in the final claims that accompany this description.
  • the invention proposes, as noted above, an air blowing accessory specially designed to be securely incorporated or attached to a sweeping or similar street cleaning machine and use of the air expelled by the sweeper or cleaning equipment to channel it and use that air to blow the waste and direct it towards the suction or transport opening, thereby avoiding the use of a traditional portable blower.
  • the blowing accessory equipment for a sweeper or similar street cleaning machine that is the object of the invention essentially comprises a flexible air-conducting tube capable of channelling the air expelled by the sweeper or cleaning equipment and using it to blow waste and direct it towards the suction opening of the machine.
  • said flexible tube is connected, at one end, to the turbine of the sweeper while at the opposite end it has an air outlet opening.
  • the equipment optionally comprises a small water conduit, which is also flexible, that allows the water tank of the sweeper or cleaning machine to be used to incorporate sprayed water into the air blown through the flexible air tube and thus capture fine dust as is done with the brushes of the sweeper and inside the suction opening.
  • said water conduit is connected at one end to the water tank of the sweeper while at the opposite end it is joined to the outlet of the flexible air tube.
  • the water tube is joined along its entire length, for example by means of flanges, to the flexible air tube.
  • the equipment may comprise various means such as a mechanical or piloted mechanism, or a handle incorporated into the tube itself to totally or partially cut off the air flow at the discretion of the operator, such that the air expelled by the turbine can be used totally or partially for blowing.
  • the amount of air that is not used for blowing will exit through the normal conduit of the cleaning equipment.
  • the flexible air tube can be of different lengths, depending on the requirements of each job.
  • the equipment comprises a rotating pole that, attached to the upper portion of the sweeper where the turbine is usually located, helps to move and distribute the weight of said tube and avoid cars parked on the pavement.
  • the equipment further comprises a fastening element such as a harness that the operator can wear at the waist, to help bear the weight of the final portion of the suction tube.
  • a fastening element such as a harness that the operator can wear at the waist, to help bear the weight of the final portion of the suction tube.
  • the weight of the flexible tube can be around 0.75 kg/m and the final tube with the handle, around 1 kg. These are weights that, in any case, are much lower than those of a portable blower that constitutes the current state of the art.
  • the blowing equipment of the invention comprises the incorporation of a small compressor or a small turbine for generating high-pressure air.
  • the weight and noise will be in the cleaning machine and not on the back of the operator and the incorporation of water in the blowing will continue to be carried out through the conduit attached to the flexible air-channelling tube.
  • blowing accessory equipment for a sweeper or street cleaning machine of the invention comprising that which is described in detail below.
  • the equipment (1) of the invention applicable for incorporation thereof into a sweeping or street cleaning machine (2) equipped with at least one water tank (3), for example to spray it through nozzles (4) located next to rotating brushes (5), and equipped or not with a turbine (6) generating pressurised air, it essentially comprises a flexible air-conducting tube (7) that is connected, at a proximal end (7a), to a turbine (6) of the sweeping machine (2) itself, or to a turbine or air compressor installed for this purpose in the machine (2), and the opposite end or distal end (7b) of which has an air outlet opening (8), enabling the air expelled by said turbine (6) of the machine (2) to be channelled and used, handled by an operator, to blow waste and direct it, preferably, towards the suction area (2a) of the machine (2) itself.
  • the equipment (1) of the invention further comprises a water conduit (9), also flexible, which is connected at a proximal end (9a) to the water tank (3) of the machine (2) and joined at the distal end (9b) to the air outlet opening (8) of the flexible air tube (7) enabling sprayed water to be incorporated into the air blown through the flexible air tube (7).
  • a water conduit (9) also flexible, which is connected at a proximal end (9a) to the water tank (3) of the machine (2) and joined at the distal end (9b) to the air outlet opening (8) of the flexible air tube (7) enabling sprayed water to be incorporated into the air blown through the flexible air tube (7).
  • the water conduit (9) is attached along the entire length thereof to the flexible air tube (7), for example by means of flanges (10) distributed along the same and has a tap (11) to regulate the passage of the water.
  • the flexible air tube (7) comprises means for regulating the air outlet such as a butterfly valve (12) and/or a control handle (13) incorporated into the tube (7) itself to regulate or cut the air flow completely or partially at will.
  • a butterfly valve (12) and/or a control handle (13) incorporated into the tube (7) itself to regulate or cut the air flow completely or partially at will.
  • valve (12) and/or the control handle (13) have piloted mechanisms and are connected with electrical cables (14) that provide electrical power from the machine (2), said cables being attached to the flexible tube (7) through the aforementioned fastening flanges (10).
  • the inclusion of a section of rigid tube (7c) where the handle (13) is incorporated is contemplated between the distal end (7b) of the flexible air tube (7) and the air outlet opening (8).
  • the air outlet opening (8) has a conical configuration to force a Venturi effect that increases the outlet pressure of the air.
