Description

Vynález sa týká preťahovacieho zariadenia hlavně k odvětvováním hlaviciam.The invention relates to a stretching device mainly for branching off the heads.

Doposiaí sa pri odvětvovaní stromov pomocou roznych odvetvovacích hlavic používajú na pretiahnutie stromov cez odvetvovacie nože, preťahovacie válce alebo sa na pretiahnutie používá tahač alebo lanové preťahovacie zariadenie.Up to now, when branching trees using various branching heads, they have been used for pulling trees through branching knives, pulling rollers, or using a tractor or rope pulling device for pulling.

Nevýhodou takéhoto pretahovanla je u prefahovacích valcov malá styková plocha ako aj poškodenie kmeňa stromu hrotmi týchto valcov. Pri přetahovaní pomocou lanového systému je potřebný dlhý výložník s vodlacimi plochami. Preťahovanie pomocou tahača je náročné na priestor a terén pričom je dost nákladné.The disadvantage of such stretching is the small contact surface of the deburring rolls as well as the damage to the tree trunk by the tips of these rolls. When pulling with a rope system, a long boom with guide surfaces is required. Towing with a tractor is space and terrain demanding and costly.

Uvedené nedostatky v podstatě odstraňuje preťahovacie zariadenie hlavně k odvetvovacím hlaviciam podlá vynálezu, ktorého podstata spočívá v tom, že na spoločnom spodnom ráme je uchytená odvetvovacia hlavica, preťahovací pás pevný s bubnom napínacím a hnacím pomocou hydromotora, vrchný rám s vedením a priamočiarym hydromotorom, piričom v spodnom ráme sú uchytené vodiace kladky a rám je uchytený pomocou upínacích elementov k rámu přepravného prostriediku s nakládacím zariadením s drapákom. Vo vrchnom ráme s vedením je uchytený na jeho vedení posuvný rám v ktorom je uchytený preťahovací pás posuvný s bubnom napínacím a hnacím pomocou hydromotora a zároveň sú v posuvniom ráme uchytené vodiace kladky. Pretahovacie pásy pozostávajú z hnacích reťazí na ktorých sú uchytené látky. Vonkajšle hrany latiek majú mierne prevýšeňle pre lepšle stredenie odvětvovaného stromu. Najvýhodnejšie je umiestniť preťahovacie zariadenie hlavně k odvetvovacím hlaviciam na rám stroja na spracovanie stromov.The above drawbacks are substantially eliminated by the draw-off device mainly to the branch heads according to the invention, which consists in that the common bottom frame holds the branch head, the stretch belt fixed with the drum tensioning and driving by hydraulic motor, the upper frame with guiding and linear hydraulic motor guide rollers are mounted in the lower frame and the frame is secured by means of clamping elements to the frame of the transport means with the loading device with a grab. In the upper frame with the guide is mounted on its guide sliding frame in which the attached stretch belt sliding with the drum tensioning and driving by a hydraulic motor and at the same time are mounted in the sliding frame guide rollers. Stretching belts consist of drive chains on which fabrics are attached. The outer edges of the slats are slightly elevated for better centering of the branched tree. Most preferably, the pulling device is mainly located to the branch heads on the frame of the tree processing machine.
