Description

Scattered bamboos fell saw
Technical field
This technology belongs to woods bamboo logger technical field, and in particular to a kind of Scattered bamboos fell saw.
Background technology
China is the kingdom of bamboo, bamboo as China's forestry ten big rising industries first of, it has also become be southern hillses The pillar industry of mountain development.
With scientific and technological progress and the implementation of some Bamboo Forest High Yield Culture measures, at present, the extensive operation bamboo grove of large area becomes For intensive farming, after the transformation of low yield forest land, bamboo grove structure is improved, however, with the extension of the time of operation, managing intensity Increase, operating cost is improved rapidly, is mainly manifested in, labour cost needed for bamboo stalk is felled is too high, bamboo grove, which fells cost, have been turned into Restrict the key factor of China's Bamboo Industry Development.
ZL200820123306.6 discloses a kind of tree felling machine, the harvester collection lumbering, delimbing, papermaking, section tip etc. Multi-functional in one, operating efficiency is high, safety, saves manpower, damages smaller to forest and forestry ecology, however, this is felled Machine is larger because of volume, is only suitable for the small stand type of density, and operation can not be carried out in the bamboo grove of conventional operation. ZL03211293 discloses a kind of forest protection cutting machine, the characteristics of this machine is designed be provided with column and some tree-cohesion mechanisms, can To prevent trees from being lodged during felling to side, but tree-cohesion mechanism set by this machine is excessive, and operating process is more Complexity, therefore the efficiency of felling is have impact in actual mechanical process, and also the equipment volume is larger, in the bamboo that vertical bamboo degree is larger More difficult movement in woods.
2011103610706 disclose a kind of Special bamboo feller, including by gasoline engine driven circular saw, it is described Circular saw is located on slide rail, and spring is provided with slide rail, and the handgrip for being used for fixing bamboo pole is provided with before slide rail, and described handgrip leads to Connecting rod is crossed with fix bar to be connected;Described slide rail is connected by support with chassis, and handgrip is connected with chassis;Fix bar and chassis It is connected, in fix bar and chassis provided with manipulation locking device., can be tightly solid by woods bamboo by the handgrip of front end when this equipment works It is fixed, Lin Zhu can be made to be constantly in erectility during felling, the quality of bamboo wood is effectively ensured during felling.But this sets Standby still complicated, manufacturing cost is high, and volume is big(Long 580mm × wide 470mm × high 360mm), it is not suitable in spacing very little Bamboo grove between use.
Bamboo is generally divided into Scattered bamboos, Cluster Bamboo and mixes raw bamboo.Scattered bamboos bamboo whip is extended laterally in soil, the stem of underground On have on section, section and have bud, its bud saved develops into bamboo shoot or whip, and the bamboo strain of ground is scattered in sparse scattered shape, such as mao bamboon, thunder Bamboo etc..Bamboo whip of the subterranean stem of Cluster Bamboo without cross growth, its subterranean stem is really what is be made up of stalk base and stalk handle, thick short Contracting, section heave root is more.Therefore, the gap of gap ratio Scattered bamboos is smaller between each bamboo in Cluster Bamboo, such as green bamboo, sinocalamus latiflorus, big Head allusion quotation bamboo etc..It is to have the rhizomatous feature of Scattered bamboos to mix raw bamboo subterranean stem, there is the rhizomatous feature of Cluster Bamboo again, forms mixed raw type Bamboo grove.Such as bitter bamboo, tea stalk bamboo.
The gap ratio Cluster Bamboo of Scattered bamboos is big, but bamboo, for other plants, spacing is smaller.Therefore, bamboo is reduced The appearance and size that son fells device is always what those skilled in the art pursued.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, appearance and size is small, easy to operate, suitable for being adopted to Scattered bamboos The Scattered bamboos cut down fell saw.
Scattered bamboos described in this technology fell saw, including a housing, and the front end both sides of housing have two relative cards Arm, in relative snap arm and with being provided with approximately the same plane and rising as high as the banks of being connected in housing, the both sides of saw blade and after In portion stretches into and risen as high as the banks, the front portion of saw blade has the toothed edge for unidirectional sawing Scattered bamboos, and two snap arm extend beyond forward saw Tooth side;Having in housing rear end is used to drive the reciprocating drive mechanism that saw blade is moved back and forth between two snap arm;It is described reciprocal Drive mechanism in the connector for interior extension of rising as high as the banks with saw blade by being connected.
The beneficial effect of this technology:It is moved along in use, whole Scattered bamboos are felled saw so that the bamboo felled enters Enter between two snap arm of toothed edge, then drive saw blade to move back and forth by reciprocating drive mechanism.Because sawtooth is Unidirectional, so saw blade can be cut when being moved toward a direction, it can not be cut during reverse movement.When saw blade is carried out During cutting, due to the effect of the counter-force of cutting force, Scattered bamboos can be caused to fell saw relative to the bamboo movement felled, so that must So so that one of snap arm is contacted with the bamboo felled, and form the positioning that Scattered bamboos are felled with saw.It can so avoid Operator itself is felled saw to Scattered bamboos and is balanced using external force with cutting force, that is to say, that operator is without past in saw blade The direction moved again applies the external force being balanced with cutting force.Certainly, operator needs moving back and forth perpendicular to saw blade Scattered bamboos are promoted to fell saw on direction forward, to realize the feeding of saw blade, until whole bamboo is sawed-off.
When bamboo by it is sawed-off when, sawed as operator continues to promote Scattered bamboos to fell forward, at least by staying in after sawed-off Housing forward end on ground between the root upper end meeting of bamboo and two snap arm is contacted, and is prevented Scattered bamboos from felling saw and is moved further along Dynamic, this, which enables to operator to perceive, need not be further continued for promoting Scattered bamboos felling to saw forward, so using more convenient.
Further, since in the both sides and rear portion of saw blade in this technology stretch into and rise as high as the banks, when bamboo is sawed-off after, will be scattered Raw bamboo felling saw retracts i.e. withdrawing backward when, two sides of saw blade and the edge at rear portion will not be contacted with bamboo, will not be to moving back Knife is counteracted, and also ensure that saw blade will not fracture certainly.
The distance between in this technology, because the both sides of saw blade are stretched into rising as high as the banks in snap arm, so on the outside of two snap arm Only need to more slightly longer than toothed edge, that is to say, that can be smaller the distance between on the outside of two snap arm in this technology, so this Scattered bamboos are felled between saw can extend into the less Scattered bamboos of spacing and Scattered bamboos are felled.
