JYRSIN TURPEEN TUOTTAMISEKSIMILLING MACHINE FOR PEAT PRODUCTION

Keksinnön kohteena on jyrsin turpeen tuottamiseksi, johon jyrsimeen kuuluu pyöritettävä lieriö, joka on varustettu terä-5 elementillä, joka leikkaa suon pinnasta paloja ja heittää ne kenttään. Keksintö on tarkoitettu sovellettavaksi sekä polttoturpeen että kasvuturpeen tuottamiseen.The invention relates to a cutter for producing peat, which cutter comprises a rotatable cylinder provided with a blade-5 element which cuts pieces from the surface of the bog and throws them into the field. The invention is intended to be applicable to the production of both combustion peat and growing peat.

Nykyisin käytetään pääasiassa kahdenlaisia jyrsimiä. Ruuvijyr-10 simissä lieriön pinnalla on spiraalin muotoinen terä, joka pyöriessään irrottaa turvetta suon pinnasta. Tällaisen jyrsimen tehon tarve on suuri tuotettuun turvemäärään nähden. Toisaalta käytetään piikkijyrsimiä, joissa lieriön pinnalle on hitsattu suuri määrä piikkejä. Tämän jyrsintyypin haittana on saatavan 15 turvemassan epähomogeenisuus. Suuri osa saatavasta turvemassasta on hyvin hienojakoista.Today, two types of cutters are mainly used. The screwdriver-10 sim has a spiral-shaped blade on the surface of the cylinder, which rotates to remove peat from the surface of the bog. The power requirement of such a cutter is high in relation to the amount of peat produced. On the other hand, mandrel cutters are used in which a large number of mandrels are welded to the surface of the cylinder. The disadvantage of this type of mill is the inhomogeneity of the 15 peat masses obtained. Much of the peat mass obtained is very fine.

Tämän keksinnön tarkoituksena on aikaansaada uudenlainen jyrsin, jolla aikaansaadaan tasalaatuista ja raemaista turvetta. Keksin-20 non tunnusmerkilliset piirteet on esitetty oheisissa patenttivaatimuksissa. Keksinnön kannalta on oleellista, että jyrsin leikkaa suon pinnasta kahdelta sivulta massapalan irti, jonka kuppiosa tiivistää ja repäisee suon pinnasta irti. Saatava turvemassa koostuu tällöin pääosin samankokoisista ja tiiviste-25 tyistä massapaloista.The object of the present invention is to provide a new type of cutter which provides uniform and granular peat. The characteristic features of the invention are set out in the appended claims. It is essential for the invention that the cutter cuts a piece of pulp from the surface of the bog on two sides, the cup part of which seals and tears off the surface of the bog. The peat mass obtained then consists mainly of pieces of pulp of the same size and sealed.

Seuraavassa keksintöä selostetaan oheisten kuvien avulla, jotka esittävät keksinnön erästä sovellutusmuotoa.In the following, the invention will be described with the aid of the accompanying figures, which show an embodiment of the invention.

30 Kuva 1 esittää keksinnön mukaista jyrsinlieriötä.Figure 1 shows a milling cylinder according to the invention.

Kuva 2 esittää kuvan 1 jyrsinlieriötä päästä katsottuna.Figure 2 shows an end view of the milling cylinder of Figure 1.

Jyrsimen rungon muodostaa lieriö 1, jonka päälle teräelementti asennetaan. Tämä muodostuu kehän suunnassa useista peräkkäisistä 35 terärivistöistä 2, jotka edelleen muodostuvat kukin rinnakkain yhteenliitetyistä U-kappaleista 3. Nämä U-kappaleet on hitsattu lieriön pintaan kiinni ja niiden haarat on liitetty toisiinsa ja liitos on teroitettu, jolloin se muodostaa suon pintaa leik-kaavan kärkiosan. Tämä kärkiosa 4 on muuta osaa korkeampi.The cutter body is formed by a cylinder 1 on which the blade element is mounted. This consists in the circumferential direction of a series of successive rows of blades 2, each further formed by U-pieces 3 joined in parallel. These U-pieces are welded to the surface of the cylinder and their branches are joined together and the joint is sharpened to form the tip of the groove. . This tip part 4 is higher than the other part.
