Description

A kind of device of gathering forest cone

The utility model is a kind of device of gathering forest cone, and it is mainly used in the cone collection in the coniferous tree seed production stand, and the larch cone is particularly suitable for gathering.

Aspect the collection of forest cone, at present, seed orchard and seed production stand have been had in mild forest zone in some forestry developed countries, arrived seed maturity and connect seed: then mainly adopted in the forest zone, mountain region and manually climb the tree at shop, ground Polypropylence Sheet, pluck cone with handheld tool, and developed some novel seed collecting machineries, and as: lift, trunk bobbing machine, whole tree cone harvesting machine, helicopter collection etc.At home, the normal source of forest cone should be to adopt shallow fruit maturation woods and manually climb the tree and collect seed with handheld tool folding sprig.In the cone maturing stage, all there is a large amount of cutting bough even cut down the phenomenon generation that elite stand is collected seed privately in each forest zone but in fact.The seed collecting instrument of manually climbing the tree has: the pedal of climbing the tree, the seed collecting cutter, cut, comb etc.The more advanced outer pushing-type seed collecting device of the broach that the development of woods pipe office scientific research institution, Daxing'an Mountainrange is arranged (people climbs the tree, and hand-held this instrument is combed cone along the branch direction of growth to extrapolation).China has also carried out some researchs aspect machinery seed collecting, but all fails to come into operation effectively.Above Seed Collecting Methods and equipment cut both ways, and the labor strength that has is too big, and is dangerous; The meeting major injury elite stand that has; The equipment that has is very huge, cost is high, cost an arm and a leg.In a word, the acquisition technique and the equipment of forest cone far can not meet the needs of production at present.

The purpose of this utility model is on the basis of the size of physiological characteristic, the regularity of distribution and the harvesting power of the different seeds cone of analysis and research and direction, develop and do not damage elite stand and young fruit substantially, the collecting efficiency height, the device of pruned collection cone safe and convenient to use.The change the outfit collection pawl of different size of this device just can be plucked the cone of different seeds, have intellectuality, seriation, unitized characteristics, can make the forest zone, various places at the cone maturing stage seed of in time gathering in a large number, thoroughly stop to cut down the phenomenon that keeps elite stand seed collecting and take place, have remarkable economic efficiency and social ecological benefits.

To build group seeds larch be the target seeds in the speed life of Beilin District to the east of the purpose of this utility model was achieved in that, do the chassis with the widely used J-50 tractor in forest zone, remove skiddings such as winch, board mounting, manipulator and the pumping plant and the fruit-collecting box of 5 degree of freedom of repacking.Manipulator is made up of rotary disk, column, big arm, forearm and collection pawl, the collection pawl be two can folding large-scale broach.This device adopts double pump double loop hydraulic system drive, therefore can realize gathering the flexible interlock of operation and whole single action actions.All control valves of hydraulic system are controlled by one-chip computer.When gathering forest cone, tractor is parked in apart from elite stand 3-5 rice at a distance, hangs up take-off and drives hydraulic oil pump, handles one-chip computer and gathers operation by the sequence controlled machine hand that is solidificated in the EPROM chip.Utilize the big forearm of manipulator will gather pawl and give rise to the branch place.Two broach gathering pawl close up embraces whole branch, and outwards strip goes out cone under big forearm acting in conjunction, finishes once and plucks.Do action just can be plucked clean with putting in order the tree cone.

Owing to adopt such scheme, every machine-team can be gathered about larch cone 500kg, pick up rate and seed collecting efficient are all higher, approximately be that the workman climbs the tree 30～35 times that collect seed, the workman stands on the ground and handles, and safety is good, and is also less to the damage of elite stand, can gather the in a large number in time cone of larch and other coniferous specieses has certain generalization, seriation, intelligentized characteristics.Sustainable development to forestry has remarkable economic efficiency and social ecological benefits.This device has popularizing application prospect preferably.
