Abstract

En hjulyxa används för att göra brännved av kvistade trädstammar. I hjulyxan kan även mycket stor hastighet användas eftersom virket inte stannar under skärningen. Energikonsumtionen är låg eftersom inga onödiga skärningar förekommer. Klyvning och sned kapning av virket gör torkningen av veden snabbare. Trämaterial som blir över vid gallring av skog kan utnyttjas som brännved med hjälp av hjulyxan.A wheel luxury is used to make firewood from twigs of tree trunks. Very high speed can also be used in the wheel axle because the wood does not stop during cutting. Energy consumption is low as no unnecessary cuts occur. Splitting and cutting of the wood makes the drying of the wood faster. Wood material that is left over during thinning of forest can be utilized as firewood with the help of the wheel ax.

Description

Pyöräkirveswheel ax

SelitysExplanation

Yleinen osaGeneral section

Pyöräkirves on pilkekone joka leikkaa karsituista puunrungoista polttopuita. Pyöräkirveellä voidaan leikata puuta suurella nopeudella koska siinä puuta ei pysäytetä leikkauksen ajaksi kuten perinteisissä pilkekoneissa tehdään. Pyöräkirveen ensisijainen käyttökohde on taimikosta poistettavien ohuiden puunrunkoje ( halkaisija alle 10 cm ) leikkaaminen polttopuiksi karsinnan jälkeen.The wheel ax is a jigsaw that cuts firewood from pruned tree trunks. The wheel ax can be used to cut wood at high speed because it does not stop the wood during cutting as is the case with traditional chopping machines. The primary use of the wheel ax is to cut thin tree trunks (less than 10 cm in diameter) to be fired after pruning.

Nykyisin tunnetuissa laitteissa (Julkaisut US 3387524 A, US 6289953 Bl, US 2004223818 AI ja W02007071814 AI) ei liikkuvaa puuta samanaikaisesti halkaista ja katkaista pilkkeiksi.In presently known devices (US 3387524 A, US 6289953 B1, US 2004223818 A1 and WO2007071814 A1), moving wood is not simultaneously split and chopped.

Erityinen osaSpecial section

Seuraavassa pyöräkirvestä selitetään viittaamalla oheisiin kuvioihin, joissa kuvio 1 esittää leikkaavia teriä puun(16) menosuunnassa katsottuna, kuvio 2 esittää leikkaavia teriä katsottuna sivulta puun(16) kulkusuuntaan nähden ja samalla halkaisevat terät(9 ja 10) näkyvät kohtisuorassa sivulta. Katkaisevat terät(l8) ovat halkaisuterien (9 ja 10) ulkokehällä 45 asteen kulmassa(18) halkaisuterään nähden, kuvio 3 esittää yhtä halkaisuterää(lO) kohtisuorassa sivulta katsottuna, jossa on yksi katkaisuterä(8). Halkaisuterän(lO) halkaisija on(15), kuvio 4 esittää halkaisuterää(lO) ja katkaisuterää(8) katsottuna kohtisuoraan leikkaavaa särmää vastaan, kuviossa 4 on kuvattu pistekatkoviivalla ajateltu leikkauslieriö(ll), jonka pinnalla kaikki leikkaavat särmät ovat ylä- ja alaterässä ja kuvio 5 esittää kohtisuorassa sivulta leikkauslieriön(ll) leikkausta(12). Katkaisevan terän(8) leikkaava särmä(19) on osa tätä ellipsin muotaista leikkausta(12). Ellipsin pikkuakseli(13) on sama kuin halkaisevan terän(10) halkaisija(15).In the following, the wheel ax will be described with reference to the accompanying figures, in which Fig. 1 shows the cutting blades viewed in the forward direction of the wood, Fig. 2 shows the cutting blades viewed from the side relative to the running direction of the wood The cutting blades (18) are on the outer circumference of the splitting blades (9 and 10) at a 45 degree angle (18) to the splitting blade, Fig. 3 shows one splitting blade (10) perpendicular to the side with one cutting blade (8). The splitting blade (10) has a diameter (15), Figure 4 shows a splitting blade (10) and a cutting blade (8) viewed perpendicular to the cutting edge, Figure 4 is a dotted dashed cutting cylinder (II) Fig. 5 is a vertical side view of a section (12) of a cutting cylinder (II). The cutting edge (19) of the cutting blade (8) is part of this elliptical cut (12). The minor axis (13) of the ellipse is the same as the diameter (15) of the splitting blade (10).

Leikkausellipsin isoakseli(14) on neliöjuuri kaksi kertaa halkaisevan terän(lO) halkaisija (15) koska niiden välinen kulma(18) on 45 astetta.The major axis (14) of the cutting ellipse is the square root twice the diameter (15) of the splitting blade (10) because the angle (18) between them is 45 degrees.

Claims (3)

PatenttivaatimuksetThe claims 1. Pyöräkirves on pilkekone joka käsittää kaksi vastakkaisiin suuntiin pyörivää kiekkomaista halkaisuterää(9,10) ja niihin kiinnitetyt katkaisuterät(l-8) on tunnettu siitä, että se samanaikaisesti halkaisee ja katkaisee liikkuvaa puuta(16).1. The wheel ax is a chopper comprising two disc-shaped splitting blades (9,10) rotating in opposite directions and the cutting blades (1-8) attached thereto, characterized in that it simultaneously splits and cuts the moving wood (16). 2. Patenttivaatimuksen 1 mukainen pilkekone on tunnettu siitä, että sen katkaisuterien(l-8) leikkaava särmä(19) on osa ellipsiä jonka pikkuakseli(13) on yhtä pitkä kuin halkaisuterän halkaisija(15).The chopper according to claim 1, characterized in that the cutting edge (19) of its cutting blades (1-8) is part of an ellipse whose minor axis (13) is as long as the diameter (15) of the splitting blade. 3. Patenttivaatimuksen 1 mukainen pilkekone on tunnettu siitä, että halkaisuterissä(9,10) on lovet(17) helpottamassa halkaisun aloittamista.The chopper according to claim 1, characterized in that the splitting blades (9,10) have notches (17) to facilitate the initiation of splitting.
