Abstract
Vorrichtung und Verfahren zur Erzeugung von unterschiedlichen Luftströmungskanälen.Der Blasausgang eines Laubbläsers war bisher nur starr und nicht flexibel einstellbar, so dass nur ein vorgegebener Luftausströmungskanal erzeugt wurde.Um unterschiedliche Luftströme eines Laubbläsers zu erzeugen, wird ein Mechanisches-Elektrisches System im Blasrohr hinzugefügt, die den erzeugenden Luftstromkanal verändert und individuell anpasst.Das verstellbare Blasrohr eignet sich nicht nur zur Beförderung von Laub, es kann jetzt angepasst werden an das Beförderungsgut mit zusätzlich verbesserter Leistung.Device and method for generating different air flow channels. The blow outlet of a leaf blower was previously only rigid and not flexibly adjustable, so that only a given air outflow channel was generated. In order to generate different air flows of a leaf blower, a mechanical-electrical system is added to the blow pipe, changed and customized the generating airflow channel. The adjustable blowpipe is not only suitable for conveying leaves, it can now be adapted to the conveyed material with additionally improved performance.
Description
Laubbläser und deren Einsatzgebiete.Leaf blowers and their areas of application.
Wenn getrocknetes Gras, Laub oder Schmutz schnell von Ihrer Einfahrt, Terrasse, Bürgersteig oder von den Rasenflächen entfernen müssen, ohne diese zur Entsorgung aufzunehmen, dann sind Laubbläser im Vorteil.When you need to quickly remove dried grass, leaves or debris from your driveway, patio, sidewalk or lawn without picking it up for disposal, then leaf blowers come into their own.
Ein Blasrohr eines Laubbläsers ist am Blasausgang starr und nicht flexibel verstellbar.A blow pipe of a leaf blower is rigid and not flexibly adjustable at the blow outlet.
Um eine Düsenform am Blasausgang am Blasgerät vorzunehmen, wird ein mechanisches Verstell-System hinzugefügt.A mechanical adjustment system is added to make a nozzle shape at the outlet of the blower.
Ein Universal Blasrohr dient zur Erzeugung von unterschiedlichen Luftstrom-Ausgangs-Kanälen (Formen) am Blasrohr.A universal blowpipe is used to create different airflow outlet channels (shapes) on the blowpipe.
Durch unterschiedliche Luftausströmungs-Kanäle (sei es ...flacher, runder, kleiner, großer oder selbst angepasster) wird ein Luftausstromkanal so erzeugt, dass dieser passend zur aktuellen Schmutzbeförderung dient und dadurch verbessert wird.Through different air outflow channels (be it ...flatter, rounder, smaller, larger or customised) an air outflow channel is created in such a way that it is used to suit the current dirt transport and is thereby improved.
Durch den angepassten Luftstromausgangskanal, der manuell eingestellt werden kann, kann dieser nicht nur speziell Laub befördern wie gewöhnliche Laubbläser mit gewöhnlichem Blasrohr. Unterschiedliche Schmutzarten die sich auf dem Boden befinden, werden dadurch verbessert befördert wie z.B., nasses Laub, hartnäckiger Schmutz, Schmutz in Fugen, Schnee, Schneematsch, Schmutz der schwerer als Laub ist.Due to the adapted airflow outlet channel, which can be adjusted manually, it can not only transport leaves like ordinary leaf blowers with an ordinary blower tube. Different types of dirt that are on the ground are thus transported better, such as wet leaves, stubborn dirt, dirt in joints, snow, slush, dirt that is heavier than leaves.
Durch manuelle Betätigung eines mechanischen Systems Abb.M1 der als Zusatz oder eingebaut vor dem Blasrohr oder im Blasrohr Abb. B1 befindet (sei es mit Hilfe einer Dreh-Schablone, durch eine drehbare Irisblende, eine Klappe usw.) wird dafür gesorgt, dass der erzeugte Luftstrom der aus dem Blasgerät entsteht Abb. L1 mit Hilfe des Mechanischen Systems M1 im Querschnitt Abb. A1 verjüngt und die gewünschte Blasausgangs-Form Abb.L2 der zum Einsatz benötigt wird, erzeugt. Die auszuströmende Luftgeschwindigkeit Abb. L2 nimmt gleichzeitig durch die Verjüngung zu und der passende Luftausströmungskanal wird erschaffen. Dieses verstellbare System, hat den Vorteil, 1.dass man sich keine starren Zusatzrohre mehr kaufen muss, 2. Die Luftgeschwindigkeit manuell verstärkt/erhöht werden kann ohne ein neues Gerät mit stärkeren Leistung zu kaufen und 3. Nicht nur Laub befördert werden kann, 4. Vor Ort die passende Einstellung ändern kann angepasst an das Beförderungsgut.Manual actuation of a mechanical system Fig.M1 which is added or installed in front of the blowpipe or in the blowpipe Fig. B1 (be it with the help of a rotating template, a rotating iris diaphragm, a flap, etc.) ensures that the The air flow generated from the blower Fig. L1 is tapered with the help of the mechanical system M1 in cross section Fig. A1 and the desired blow outlet shape Fig.L2 required for use is generated. The outflowing air speed Fig. L2 increases at the same time due to the taper and the appropriate air outflow channel is created. This adjustable system has the advantage that 1. you no longer have to buy rigid additional pipes, 2. the air speed can be boosted/increased manually without buying a new device with more power and 3. not only leaves can be transported, 4 .Can change the appropriate setting on site, adapted to the cargo.
