Description

Ramie stripper

The utility model belongs to a kind of will tear the farm machinery that the ramie fiber crops skin that peels scrapes off numb shell.

Because the domestic and international market is big to the demand of ramie, China's ramie production development is very fast, and cultivated area enlarges day by day, it is reported, the 1986 kind pitted skins of being only the Hunan Province amass and have reached 1,100,000 mu, increase by 205.9% than 1985, expect will continue from now on to occur kind of " a ramie heat ".But in 1 year three season of results of ramie, seasonality is very strong, can not adapt to current ramie production development situation with original manual mode scraping, and therefore vast numb farming presses for a kind of practical ramie fiber crops skin stripper that suits.

The facility of at present existing several similar applications come out, wherein more representational a kind of be the 6BZ-40 type decorticator of Yuanjiang crudefiber crop research institute of the Chinese Academy of Agricultural Sciences and Yuanjiang county agricultural machinery factory's cooperation research and development, another kind is eight No. hundred agricultural machinery factories, Nan County, Hunan and the 6BM-40A type decorticator (number of patent application is 86208222) of economizing the cooperation design of Machine Design institute, these two kinds of decorticators are all similar on structure on the operation principle, all be that the whole strain straw that limits to cut receipts is a processing object, multiple tooth cylinder with rotation at a high speed carries out the brute force strike, pulverize the shell and the in-seam of straw, reach the purpose that strips flax fibre.The problem that this type exists at first is that ramie picking methods and existing rational tillage system are not inconsistent, according to numb agricultural consistent the reflection, take the desired stem method of cutting of this machine to receive fiber crops than receiving fiber crops with the common pico farad that tears, remove toothing and shorten ramie length, this season just loses to be received beyond about 2%, more seriously the numb root and stem of certain plants is caused damage, make the following season ramie can not be as with tearing the pico farad stout and strong new talent that afterwards regenerates of gathering from root and stem of certain plants root position, but around cutting batch fracture, sprout extremely many thin and delicate tender sweet-smelling grass, this not only wastes fertilizer efficiency, bring new difficulty for the management of numb field, and the original numb output of very difficult maintenance, be that this class type itself has adopted non-general targetedly grinding mode again, the result unavoidably also can loss part flax fibre when pulverizing numb shell boon, has reduced numb yield rate; Also often have the fragment of some numb shell boons to be mixed in the flax fibre, the colloidal content in the fiber is also more, makes the finished product ramie all undesirable on profile on the color and luster, has reduced the quality grade of ramie.In addition, this class type can only be interrupted work, and the operator must hand straw and send to repeatedly and pull out, so output also is restricted.

It is object with the numb skin of the ramie of tearing receipts that the purpose of this utility model is to provide a kind of, cutter avoid all the time ramie fibrage and only at numb shell scraping, the energy continuous operation, head and the tail have once been scraped, can export the finished product fiber crops automatically neatly, can be motor-driven dual-purpose with the manpower driving, and designing the ramie fiber crops skin stripper that big latitude is arranged on the output.

The utility model mainly by the two pairs of material rollers in front and back, about two cutterheads, elasticity support curette, the stake of collection fiber crops, frame, power and transmission system and form.Two pairs of material rollers have identical textural association, wherein top roll can fluctuate under adjustable spring pressure slightly, be shaped on the multi-head spiral line of the numb skin of horizontal promotion on the working face of outer garden, the outer garden of lower roll working face is shaped on the axial groove of longitudinal feed fiber crops skin, and the top roll rotating speed is greater than the lower roll rotating speed.Utilizing this different operating face structure and the speed discrepancy of upper and lower roll, make numb skin both by the outer garden linear velocity longitudinal feed of lower roll, is that speed laterally promotes with top roll to the relative rotation speed of lower roll and the product of self helical helical pitch again, and the result just orders about the oblique translation of numb skin.About two coaxial being installed in the middle of two pairs of material rollers of cutterhead, radially fix 8 on each cutterhead and make blade with 8 ° of-10 ° of relief angles with high manganese steel sheet, left cutterhead moves towards rotation along numb skin, turning to of right cutterhead is opposite with numb skin trend.The elasticity on cutterhead top is supported curette and is embedded with the arc rubber slab, and the garden arc radius of its working face is a bit larger tham nose radius, is beneficial to steady feed, and the thickness that approaches the ramee layer is adjusted in the gap of rubber slab and point of a knife, makes blade can not damage flax fibre all the time.Supporting the curette two ends also has the spring of adjustable degree of tightness to exert pressure, and keeps the yielding performance of appropriateness.During work, with numb cot face down be admitted to after the in the past material roller left end feeding the left cutterhead that rotates in the same way with between the curette, because of point of a knife speed much larger than numb skin speed, make each point of a knife can both scrape off a bit of numb shell, when numb skin the last period in oblique translation, being scraped off numb shell by left cutterhead, the fiber crops head immediately clamped by a pair of material roller in back and slave after the left side spue.When numb skin continues traversing during to the machine middle part, the right cutterhead of reverse rotation just the back one section numb shell that scrapes off numb skin by means of back material roller clamping fiber crops bark graft, because of the relative speed difference and the left cutterhead of right cutterhead point of a knife and numb skin basic identical, so each point of a knife of right cutterhead also can scrape off one section numb shell of equal length, and because the multiplicity of point of a knife trace on numb skin movement locus is big, so can fully squeeze the colloid in the clean flax fibre, improve the cleanliness of scraping of finished product fiber crops.During to the whole scraping of full wafer fiber crops skin, the right side went out machine after numb tail had moved on to machine the right and slave.In the middle part of but the collection fiber crops stake of move left and right location vertically is placed in behind the machine, utilize the first numb tail of above-mentioned fiber crops to go out the cross directional variations that put the seat in the plane, therefrom hold the finished product fiber crops, because the feeding position of all numb skins is identical, the seat in the plane that goes out of fiber crops head is put also inevitable identical, no matter so how the density of numb skin feeding spacing changes, finished product fiber crops fitly lodge phenomenon at random or uneven can not occur in the stake of collection fiber crops.
