Description
Technical field
The present invention relates to a kind of wheel, particularly relate to a kind of wheel that is used for forestry industry.
Background technology
Modem forestry practice is usually utilized the mechanical harvesting machine, becomes different length to cut down trees, to remove side shoot and cut trunk in single process.
The mechanical harvesting machine generally includes a reaping machine head, and it is connected to the end such as the mechanical arm of the hydraulic operation machinery of excavator or wheeled harvester.Described reaping machine head is manoeuvred to the bottom of tree, and it grips trunk and utilizes the saw the be connected to described reaping machine head stub cutting trunk from described tree there.Described then trunk is driven and passes described head, removes any side shoot by the delimbing cutter that is connected to described reaping machine head.Described trunk also can be entered the position on the buttress and utilize the sawing that is connected to described reaping machine head to be slit into different length by manoeuvre.
Some hydraulic-driven wheels that trunk is connected to reaping machine head grip.Each outside contact-making surface of taking turns is near described trunk.Described contact-making surface is configured to strengthen the frictional force between it and the trunk, thereby reduces slippage, increases the speed that tree passes described head.
This can finish by Several Methods.A kind of method is commonly referred to as thumb type, utilizes some pyramidal projections from described contact-making surface, so that the high pressure spot of some relative trunks to be provided.The disadvantage of the wheel of this type is that the pressure that need grip described trunk may damage wooden bottom.If the surface of bark is very hard and highly be shaped or if described surface consequently can not be gripped effectively for projection is too sliding, then also slippage may take place.
Protection at wooden extexine is under the most important situation, and described the wheel can be made by rubber, and the chain with casting covers around described outer surface of taking turns.
The purposes that will carry out according to timber is selected the type of wheel.
For as the wood of plank, common claimed extexine is to limit described surface or near the damage of the wood on described surface.Under some these class situations, also require to keep as far as possible the bark on a large amount of trees, to reduce the painted of timber.This situation typically is used for cork, for example pine.
Can use thumb type or rubber wheel in the case.
Under other situations, wood is cut into fragment with the raw material as slurrying.This typically is applied to various hardwood, comprises eucalyptus and acacia.In these cases, wish before chip, to debark by using the peeling wheel to remove.
United States Patent (USP) 5,111,860 disclose a kind of example of apparatus for peeling off.
Typically, the outside contact-making surface of peeling wheel is configured to comprise a series of blades, and described blade is oriented the direction of rotating with wheel and intersects substantially.These blades are designed to penetrate in the bark of trunk, are clamped on the trunk thereby provide securely.For enough folder power is provided, this requires to drive tree and passes reaping machine head to remove all branches and control trunk, can accurately measure the size of trunk.
Described blade is in the corticole degree that compresses the binding between releases bark and the trunk and be removed with the permission bark to the fragmentation that promotes bark.
Described blade is configured to make trunk to rotate when passing described.
When described trunk moves through reaping machine head, give other peeling equipment by exposing more barks, such as the delimbing cutter of the front portion that is installed in reaping machine head, the rotation of described trunk improves the peeling action of reaping machine head.
If not rotation is with the otch that does not connect style of the rule that occurs vertically spreading along trunk.The trunk rotation that utilizes this blade structure to obtain, rather than produce along the continuous substantially helical-like path that also centers on described tree.
On-stream, use several peelings wheel, with fixing trunk.When causing each trunk to pass reaping machine head, this covers most of bark fast.
The combined effect that described style otch that described blade cuts out and described peeling wheel are exerted pressure compresses, tears bark and bark is broken from the appearance of trunk.
Surprisingly, although have the consideration of all detailed descriptions, utilize above-mentioned conventional peeling wheel still to have many shortcomings.Condition and type according to tree in order to remove great majority or all barks, may need to make several times trunk to pass described head.This is time taking, so increased extra charge.
Particularly, meet with many problems-generally find for the tree of bark for palohierror such as eucalyptus and acacia with hard especially bark or length and fiber.
When bark was removed from wheel, the part of bark often stopped up in the space between the lip-deep blade of wheel, causes machine down.
The method of using another peeling in some cases is to cut out otch by manual grain direction at wood, to open a tear on bark, debarks thereby remove.Be removed with the manual tearing bark of the mode of expanding described tear along the trunk direction then.The shortcoming of the method is to waste time and energy, and labourer is had potential danger.So it is not suitable for modem forestry practice.
In needs remove the situation of debarking, provide part as the mechanical harvesting process, can be effectively and in time except that the equipment of debarking of great use.
