Abstract

The utility model discloses a double-roller ramie peeling machine, which comprises a framework, a feeding hopper, two ramie peeling rollers with beating plates and a press plate. The press plate is used for crushing ramie fresh stems when feeding the same and collecting and removing impurities when peeled ramie fibers are reversely pulled out of the feeding hopper, and is mounted on the tail portion of the feeding hopper through a mounting frame on a framework. On the basis of the prior art, the double-roller ramie peeling machine is additionally provided with the press plate, and the press plate can crush the fresh stems when the ramie fresh stems are fed and primarily separate skins from interior stems, and simultaneously collects and removes impurities when the peeled ramie fibers are reversely pulled out of the feeding hopper, thereby effectively increasing ramie peeling quality. Technical parameters of the two ramie peeling rollers and the feeding hopper are preferably determined through orthogonal tests, and then the double-roller ramie peeling machine is more reasonable in integral structure, compact in model, stable in operation, labor-saving in operation and reliable in ramie peeling quality, not only is suitable for operating at fixed occasions, but also can be used in fields.

Description

The twin-roll machine for peeling ramie

Technical field

The utility model relates to a kind of machine for peeling ramie, relates in particular to a kind of twin-roll machine for peeling ramie, belongs to farm machinery.

Background technology

Ramie is China's special product, and its cultivated area and output account for total in the world cultivated area and more than 90% of output.Before the eighties, simple and easy fiber extractor or manual finishing are used in the decorticating of China ramie processing, and it is big to shell numb labour intensity, time-consuming.According to statistics, use simple and easy fiber extractor or manual striking utensil striking ramie, only the amount of labour used of stripping fiber crops just accounts for ramie and gathers in the crops more than 2/3rds of the amount of labour used from planting to.1980, Hemp Inst., China Academy of Agricultural Sciences succeeds in developing first artificial anti-pull-type machine for peeling ramie of China, nineteen ninety is succeeded in developing the small-sized machine for peeling ramie of the second generation again, the scientific research institution or the peasant household on ground such as Hunan, Hubei, Sichuan, Chongqing successively succeed in developing multiple small-sized machine for peeling ramie at present, but problems such as these machine for peeling ramie ubiquity ramie gum contents are higher, counter pull is big, the ramie striking is unclean influence applying of machine for peeling ramie.

The utility model content

The purpose of this utility model is in order to satisfy the ramie decorticating requirement at ramie plantation family on a small scale, a kind of compact conformation to be provided, to shell numb reliable in quality, to operate light labour-saving twin-roll machine for peeling ramie.

The utility model provides a kind of twin-roll machine for peeling ramie, comprise the numb cylinder of two strippings that frame, feeding hopper, band re-pack, also comprise when being used for the bright stem feeding of ramie broken bright stem and receive the pressing plate of slurry and impurity elimination when pulling out feeding hopper in that the ramee that strips is counter, this pressing plate is installed in the afterbody of feeding hopper by the installing rack on the frame.

Re-packing on the numb cylinder of described two strippings tilted 15～20 ° in the other direction along the cylinder rotation, and the back lash between the numb cylinder of two strippings is 4～6mm.

Described feeding hopper is inclined upwardly 10 °～20 °.

Because the utility model has increased pressing plate on the basis of existing technology, this pressing plate can play broken bright stem when the bright stem of ramie feeds, with the osteoderm initial gross separation; The ramee that strips simultaneously is counter also can to play the operation of receiving slurry and impurity elimination when pulling out feeding hopper, has improved effectively thus and has shelled numb quality.The utility model is preferred versions of determining by orthogonal test by some technical parameters to two numb cylinders of stripping and feeding hopper in addition, make complete machine structure more rationally, type is compact, operate steadily, rapid operation, stripping fiber crops reliable in quality, both be adapted at fixed-site work, can have used in the field again.The utility model is compared with existing machine for peeling ramie, characteristics such as have the numb work efficiency height of stripping, the numb quality of stripping is good, and bright stem fibre percentage height, raw ramie percentage of impurity are low.The quality of the ramie that shells has surpassed GB/T7699-1999 " ramie " requirement.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of Fig. 1 left view.

The specific embodiment

From Fig. 1 to Fig. 2 as can be seen, this twin-roll machine for peeling ramie of the utility model comprises base 1, power 2, one-level transmission 3, frame 4, shells numb cylinder, protective plate 6, pressing plate 7, feeding hopper 8 and secondary transmission 10.Feeding hopper 8 is installed in the top of frame 4 and opening 10 °～20 ° angles that are inclined upwardly, and can make things convenient for the feeding of ramie stem like this, reduces labor intensity; In the place ahead of feeding hopper 8 blade is installed, plays scraping and receive the purpose of starching; An installing rack 41 is arranged on the frame 4 at feeding hopper 8 rears, pressing plate 7 is fixed on this installing rack 41, when the bright stem of ramie feeds, this pressing plate 7 can broken bright stem, with the osteoderm initial gross separation, in that the ramee that strips is anti-when pulling out feeding hopper, this pressing plate 7 can also be finished the operation of receiving slurry and impurity elimination, shells numb quality to improve.Stripping fiber crops cylinder on the frame 4 is made up of numb cylinder 5 of main stripping and the numb cylinder 9 of secondary stripping, the size and the structure of two numb cylinders of stripping are identical, major-minor is shelled and respectively is equipped with 12 on the numb cylinder and re-packs 11, and re-pack 11 when installing along cylinder direction of rotation 15 °～20 ° angles that recede, can reduce the damage of the 11 pairs of ramees that re-pack like this, the back lash that major-minor is shelled between the numb cylinder is 4～6mm, when assurance ramie boon is broken, remove the numb shell on ramee surface, obtain clean fiber, protective plate 6 be installed in frame 4 above, and covered the stripping numb cylinder, the protection that has strengthened production safety.

Ramie is held the cane base portion by scutching person in the decorticating process, will be slightly portion from feeding hopper 8 feedings, in the extruding of pressing plate 7, the main numb cylinder 5 of stripping and the numb cylinder 9 of secondary stripping, bend and scrape under the effect of beating, boon is broken with numb shell, osteoderm separates; This moment, scutching person slowly oppositely pulled out ramee, and scraping under the effect of beating of the numb cylinder 5 of main stripping, the secondary numb cylinder 9 of stripping and pressing plate 7, portion's fiber is clean by striking slightly for ramie.Scutching person holds and scrapes the ramee that makes then, striking base portion in the same way, thus finish ramie decorticating process one time.Transmission mechanism of the present utility model comprises the one-level transmission 3 from power 2 to the numb cylinder 5 of main stripping, shell numb cylinder 5 is shelled numb cylinder 9 to pair secondary transmission 10 from the master, wherein the classical V-belt transmission is adopted in one-level transmission 3, and gear drive is adopted in secondary transmission 10, to guarantee the accuracy and the stationarity of transmission.
