Description
Korte aanduiding:Short designation:
SnelhoogteverstellingRapid height adjustment
De uitvinding heeft betrekking op het verstellen van de maaihoogte bij kooimaaiers.The invention relates to the adjustment of the cutting height in reel mowers.
De optimale maaihoogte van gras is afhankelijk van de ouderdom van het gewas, de bodemgesteldheid en de weersomstandigheden. De maaihoogte dient dan veranderd te worden (een tijdrovende bezigheid) of men moet terug naar de machine opslag om een andere maaier aan te koppelen (tijdrovend en duur qua investering). Het doel van de uitvinding is een zodanige konstruktie te ontwikkelen, dat het verstellen van de maaihoogte met een enkele handgreep wordt gerealiseerd, waarbij de mogelijkheid van onnauwkeurige afstelling is uitgesloten. De besparing in tijd zowel als geld is spectaculair. De thans bestaande verstelinrichtingen maken gebruik van schroefdraadspindels of sleuven ter weerszijden van iedere maaikooi, waardoor het verstellen een zeer tijdrovende bezigheid is, welke door de mogelijkheid van foutieve afstelling tevens de nodige accuratesse vraagt.The optimum cutting height of grass depends on the age of the crop, the soil conditions and the weather conditions. The cutting height then has to be changed (a time consuming activity) or one has to go back to the machine storage to connect another mower (time consuming and expensive in terms of investment). The object of the invention is to develop such a construction that the adjustment of the cutting height is realized with a single handle, whereby the possibility of inaccurate adjustment is excluded. The time and money savings are spectacular. The currently existing adjustment devices use threaded spindles or slots on either side of each reel, making adjustment a very time-consuming activity, which also requires the necessary accuracy due to the possibility of incorrect adjustment.
De snelhoogteverstelling volgens de uitvinding wordt hieronder aan de hand van de tekening, waarin een uitvoeringsvoorbeekJ is voorgesteld, nader toegelichtThe rapid height adjustment according to the invention is explained in more detail below with reference to the drawing, in which an exemplary embodiment is presented.
Fig.A Snelhoogteverstelling als setFig.A Rapid height adjustment as a set
Fig.B Snelhoogteverstelling in onderdelenFig. B Quick height adjustment in parts
De snelhoogteverstelling omvat een houder 1 met glijstang 2 en drukveer 3, een stelpen 4, een stelhout 5, een kiemblok 6 met tuimelstuk 7. De houder wordt door middel van verbindingsstang 8 verbonden met een identieke houder (in spiegelbeeld) en aangebracht ter weerszijden van de maaikooi.The quick-height adjustment comprises a holder 1 with sliding bar 2 and compression spring 3, an adjusting pin 4, an adjusting wood 5, a germ block 6 with tumbler 7. The holder is connected by means of connecting rod 8 to an identical holder (in mirror image) and arranged on either side of the reel.
Bij instelling van de hoge maaistand wordt veibindingsstang 8 verdraaid met bedieningsstang 10. De glijstangen 2 worden hierdoor uitgeschoven, aangezien deze middels tuimelstuk7 en kiemblok 6 met de verbindingsstang 8 zijn verbonden. De glijstangen 2 zijn middels montageoog 22 gekoppeld aan de (voor- of achter) looprol van de maaikooi. Een dergelijke looprol bepaalt de maaihoogte. Omgekeerd zal verdraaiing van verbindingsstang 8 in tegenovergestelde richting een lagere maaistand tot gevolg hebben. De hoge maaistand wordt exact ingesteld met stelpen 4 en aanslagnok 11. De lage maaistand wordt exact ingesteld met stelhout 5 en aanslagnok 12. Drukveer 3 heeft tot taak de ingestelde stand te bekrachtigen.When the high cutting position is set, the connecting rod 8 is rotated with the operating rod 10. The sliding rods 2 are extended thereby, since they are connected to the connecting rod 8 by means of tumbler 7 and germ block 6. The sliding bars 2 are coupled by means of mounting eye 22 to the (front or rear) roller of the cutting unit. Such a roller determines the cutting height. Conversely, rotation of connecting rod 8 in the opposite direction will result in a lower cutting position. The high cutting position is precisely adjusted with adjusting pin 4 and stop cam 11. The low cutting position is precisely adjusted with adjusting wood 5 and stop cam 12. Compression spring 3 has the task of energizing the adjusted position.
Doordat klemnok 6 draaibaar is om verbindingsstang 8 is een precieze synchrone werking van beide hoogteverstelllers in te stellen en na instelling gewaarborgd.Because clamping cam 6 is rotatable about connecting rod 8, precise synchronous operation of both height adjusters can be set and guaranteed after adjustment.
