Abstract
The utility model relates to a saw chain used for a tree harvester and aims to provide a saw chain of the tree harvester with high strength, endurance to heavy cutting load of the tree harvester, ultrahigh operation speed and high saw cutting efficiency. The saw chain used for the tree harvester is formed by riveting a left gear cutting chain piece, a right gear cutting chain piece, a connecting piece and a transmission chain piece with a chain shaft, wherein thickness of a guiding part of the transmission chain piece is 1.8-2.2mm, the thickness of a connecting part of the transmission chain piece is 2.0-2.4mm, the thickness of a side chain piece is 1.6-1.7mm, material shifting amount of each gear cutting chain piece is 3.48-3.8mm, saw kerf width is 9.2-9.8mm, diameter of the connecting part of the chain shaft is 3.2-3.5mm, the diameter of the middle part of the chain shaft is 4.8-5.2mm, height of a rivet head is 0.8-0.85mm, hole distance of each chain piece is equal, and pitch of the saw chain is 10.26-12.7mm.
Description
Technical field
The utility model relates to saw chain, relates in particular to a kind of saw chain for tree harvester.
Technical background
The saw chain that uses at present is mainly used in the hand-held type chain saws such as chain saw, electric chain saw, and weight and the power of hand-held type chain saw are all less, so the chip-load of saw chain and running speed are all little.Therefore, now use width and the thickness of various chain sheets of saw chain less, chain rivet is also thinner, and the material toggling amount of Cutting teeth chair blade is also less, and saw kerf width is less, and the guide plate that matches is also thinner, narrower.Tree harvester is a kind of large-scale self-propelled multiple operation combined machine, all work such as the operator finishes lumbering, delimbing, blocks in driver's cabin, bunch and walking, and highly efficient in productivity, the speed of cutting off trees is very fast.The cutter of tree harvester mainly is large-scale scissors, trees are cut off from root or middle part, but the timber two ends can ftracture, and can only be used for papermaking or wood-based plate, can not be used for being sawn into the plate square bar.For making tree harvester can produce the indehiscent log in two, must adopt the sawed-off trees of saw chain, but used saw chain size is tiny, intensity is low, can't bear huge chip-load and the superelevation running speed of tree harvester, will soon rupture with getting on reluctantly.
Summary of the invention
The purpose of this utility model provides that a kind of intensity is high, the huge chip-load that can bear tree harvester and superelevation running speed, tree harvester saw chain that cutting-rate is very high.
The purpose of this utility model is achieved in that described tree harvester saw chain is formed with the chain rivet riveted joint by left Cutting teeth chair blade, right Cutting teeth chair blade, brace, drive link, and saw kerf width is 9.2-9.8mm, greater than the saw kerf width 7.6-8.6mm of general saw chain.The side chain sheet thickness of described tree harvester saw chain is 1.6-1.7mm, greater than the side chain sheet thickness 1.3-1.5mm of general saw chain.The Cutting teeth chair blade material toggling amount of described tree harvester saw chain is 3.48-3.8mm, greater than the Cutting teeth chair blade material toggling amount 3.0-3.4mm of general saw chain.The drive link guide part thickness of described tree harvester saw chain is 1.8-2.2mm, much larger than the drive link guide part thickness 1.5-1.6mm of general saw chain.The drive link connecting portion thickness of described tree harvester saw chain is 2.0-2.4mm, much larger than the drive link connecting portion thickness 1.5-1.6mm of general saw chain.The chain rivet connecting portion diameter of described tree harvester saw chain is 3.2-3.5mm, chain rivet connecting portion diameter 2.6-3.0mm greater than general saw chain, the chain rivet middle part diameter of described tree harvester saw chain is 4.8-5.2mm, chain rivet middle part diameter 4.0-4.6mm greater than general saw chain, the manufactured head height of described tree harvester saw chain is 0.8-0.85mm, greater than the manufactured head height 0.7-0.75mm of general saw chain.The pitch-row of the various chain sheets of described tree harvester saw chain is equal, and pitch-row is the pitch of saw chain, and the pitch of described tree harvester saw chain is 10.26-12.7mm, and the pitch of general saw chain is less than 10.26mm.
Because the side chain sheet thickness of described tree harvester saw chain is much larger than the side chain sheet thickness of general saw chain, the drive link guide part thickness of described tree harvester saw chain and drive link connecting portion thickness are much larger than drive link guide part thickness and the drive link connecting portion thickness of general saw chain, the chain rivet connecting portion diameter of described tree harvester saw chain and chain rivet middle part diameter are all larger, the manufactured head height is also larger, so the intensity of saw chain is high, can bear huge chip-load and the superelevation running speed of tree harvester, cutting-rate is very high.
