Abstract
Description
15 20 25 30 35 40 466 750 ' 2 Lämpligtvis drivs ogräsborsten i enlighet med uppfinningen vid ett betydligt högre varvtal än det som är brukligt vid borstande. Härigenom erhålles en självrensande effekt för bors- ten d v s uppdraget ogräs kastas bort fràn borsten sà att dess tràdar àterigen kan gripa tag i ogräs nästa varv. Suitably, the weed brush is operated in accordance with the invention at a much higher speed than is usual for brushing. This results in a self-cleaning effect for the brush, ie the task of weeds is thrown away from the brush so that its threads can once again grab the weeds the next turn.
Olika typer av borstar är naturligtvis möjliga inom ramen för uppfinningen, men sannolikt är en tallriksborste en av de mer lämpliga formerna för ogräsborsten enligt uppfinningen.Different types of brushes are of course possible within the scope of the invention, but probably a disc brush is one of the more suitable forms for the weed brush according to the invention.
Ytterligare egenskaper och fördelar med uppfinningen fram- gár närmare av nedanstående beskrivning i anslutning till ett pà ritningen visat utföringsexempel. Härvid visar fig 1 en borste i enlighet med uppfinningen och fig 2 ett borstknippe i större skala.Further features and advantages of the invention will become more apparent from the following description taken in conjunction with an exemplary embodiment shown in the drawing. Here, Fig. 1 shows a brush in accordance with the invention and Fig. 2 a brush bundle on a larger scale.
Den i fig 1 visade ogräsborsten 1 är lagrad i en upphäng- ningsanordning 2 som lämpligtvis kan utgöras av en svängarm 2 eller en parallellogramupphängning. Denna är fjädrande upphängd i en arbetsmaskin, vilken ej visats. En fjäder 3 balanserar ut en del av ogräsborsten och dess drivaggregats 4 vikt. Drivagg- regatet utgöres lämpligen av en hydraulmotor som är kapabel att drivas med ett högt varvtal och som i sin tur drivs av den agg- regatet bärande arbetsmaskinen.The weed brush 1 shown in Fig. 1 is stored in a suspension device 2 which can suitably be constituted by a pivot arm 2 or a parallelogram suspension. This is resiliently suspended in a work machine, which is not shown. A spring 3 balances out a part of the weed brush and its drive unit 4 weight. The drive unit is suitably a hydraulic motor which is capable of being operated at a high speed and which in turn is driven by the work machine carrying the unit.
Aggregatet enligt uppfinningen kan naturligtvis monteras separat pà en särskild bärare härför men kan även monteras pà exempelvis en sopmaskin för att kunna utföra ogräsbekämpningen samtidigt som rengöringen av trottoaren, gången eller gatan sker. Pà detta sätt behöver ingen extra tid nedläggas pà ogräs- bekämpningen vilket gör uppfinningsförfarandet till synnerligen ekonomiskt.The unit according to the invention can of course be mounted separately on a special carrier for this, but can also be mounted on, for example, a sweeper in order to be able to carry out the weed control at the same time as the sidewalk, aisle or street is cleaned. In this way, no extra time needs to be spent on weed control, which makes the inventive process extremely economical.
Ogräsborsten 1 som är en tallriksborste innefattar ett antal koncentriska rader eller cirklar av borstknippen 5. Dessa utgöres i princip av ett stycke stàlvajer som i sin överände fastklämmes i ett rörformat fäststycke med nyckelgrepp och gänga som användes för fastsättning för borstknippet vid bors- tens stomme. Frán detta fäste sträcker sig en mantling 6 ned mot borstens nedre ände. Mantlingen 6 slutar dock ett par cen- timeter ovanför borstknippets eller vajerns 5 ände. Där mant- lingen 6 slutar spretar borstknippets vajertràdar isär till följd av i en vajer normalt förekommande inbördes krafterna mellan trådarna som i sin tur delvis är en följd av den vridna form vajrarna givits vid lindningen. Denna spiralform gör det w- 'ri-ff 10 15 20 25 30 35 466 750 3 även lätt för vajertràdarna att gripa tag i ogräset. Till följd av borstens höga rotationshastighet kastas ogräset sedan bort fràn borsten och det kan vara lämpligt att anordna en skärm 9 eller dylikt i kastriktningen för borsten så att ogrästet inte kastas för làngt utan enkelt kan uppsamlas exempelvis med samma arbetsmaskin som bär upp ogräsborstaggregatet.The weed brush 1, which is a disc brush, comprises a number of concentric rows or circles of the bristle bundles 5. These consist in principle of a piece of steel wire which is clamped at its upper end in a tubular fastening piece with a key grip and thread used for attaching the bristle bundle to the brush body. From this bracket a casing 6 extends down towards the lower end of the brush. The sheath 6, however, ends a couple of centimeters above the end of the brush bundle or wire 5. Where the sheath 6 ends, the wire strands of the bristle bundle spread apart due to the mutual forces normally present in a wire between the wires, which in turn is partly a result of the twisted shape the wires are given at the winding. This helical shape also makes it easy for the wire threads to grasp the weeds. Due to the high rotational speed of the brush, the weeds are then thrown away from the brush and it may be convenient to arrange a screen 9 or the like in the throwing direction of the brush so that the weeds are not thrown too far but can be easily collected with the same work machine carrying the weed brush assembly.
Mantlingen som omger borstknippet eller i det här fallet vajern kan utgöras av en armerad plastslang eller sannolikt ännu bättre en fastklämd stoppring som pressats på plats. Om sä önskas kan naturligtvis ett antal stoppringar anordnas efter varandra och klippas bort allt efter som man önskar förnya borsten.The sheath surrounding the bristle bundle or in this case the wire may consist of a reinforced plastic hose or probably even better a clamped stop ring which is pressed into place. If desired, a number of stop rings can of course be arranged one after the other and cut off as desired to renew the brush.
Sàsom nämnsts ovan är borstknippet i överänden ínklämt i en hylsa som i sin tur är försett med fästorgan exempelvis i form en/ en gänga eller fästöra eller dylikt för fastsättning vid borststommen, detta för att borsten skall kunna utbytas vid skada. Till följd av den synnerligen stora hastighet med vilken borsten drivs så blir centrifugalkrafterna pà borst- knippena stora och för att hindra dessa frán att böja ut allt för mycket i radiell led är ett stycke ner pà borstknippena dessa förbundna med ett mer eller mindre elastiskt runt om gående band 7 som är fäst vid borstknippena pà ett sådant sätt att det ej àker upp utan stannar kvar och häller emot utàtböj- ningen som betingas av centrifugalkrafterna. Eventuella erfor- derliga med bandet samverkande organ pà borstknippet kan även de vara fastklämda pà borstknippena.As mentioned above, the bristle bundle is clamped at the upper end in a sleeve which in turn is provided with fastening means, for example in the form of a thread or fastening ear or the like for attachment to the brush body, so that the brush can be replaced in case of damage. Due to the extremely high speed at which the brush is driven, the centrifugal forces on the brush bundles become large and to prevent them from bending out too much in the radial direction, a piece down on the brush bundles these are connected with a more or less elastic around walking band 7 which is attached to the bristle bundles in such a way that it does not slide up but remains and pours against the deflection caused by the centrifugal forces. Any necessary means cooperating with the band on the brush bundle can also be clamped on the brush bundles.
Avslutningvis skall nämnas att borttagande av ogräs inte endast är en skönhetsfräga utan också exempelvis i fallet med pàläggande av ny asfalt är det synnerligen väsentligt att fà bort ogräset eftersom det annars kommer att utgöra en brottan- visning i asfalten. Som praktiskt exempel härvid kan nämnas att ett aggregat med borsten enligt uppfinningen behövde 10 minuter för att avlägsna lika mycket ogräs som det tog två män en dag att bränna bort med blàslampa och skrapa bort. D v s en synner- ligen väsentlig besparing.Finally, it should be mentioned that weed removal is not only a matter of beauty, but also, for example, in the case of laying new asphalt, it is extremely important to remove the weeds because otherwise it will constitute a break in the asphalt. As a practical example of this, it can be mentioned that an assembly with the brush according to the invention needed 10 minutes to remove as much weed as it took two men a day to burn off with a blowtorch and scrape off. That is, a particularly significant saving.
