Description
Technical field
The present invention relates to a kind of cotton picking pin and the mechanical cotton picker of this cotton picking pin is housed.
Background technology
Many in order to solve cotton picking recruitment in season number, the problem that labor strength is large, people have developed various mechanical cotton picking embossing devices, although these device cotton picking flower efficiency are high, cotton picking amount is large, but also there is complex structure, volume is large, and the deficiency that cost is high causes common cotton planting family because of the limited and unable purchase of economic bearing, still rest on the stage of manual cotton picking, affected the spread of mechanical cotton picker.
There is a kind of large-scale cotton picker from imported from America in China, cotton picking pin is being set on its cylinder, cotton picking pin is driven and is carried out rotation simultaneously also along with drum rotating by the hydraulic mechanism in cylinder, in order to improve cotton picking efficiency, this cotton picker need to first be sprinkled water in the time of work, is beneficial to be collected from cotton boll by cylinder and cotton picking pin to increase the humidity of cotton fiber.Its weak point is, this equipment not only involves great expense, and collected cotton fiber tangles and on cotton picking pin, be not easy very much de-cottonly, uses very inconvenient.
Summary of the invention
One object of the present invention is to provide a kind of cotton picking pin, can either improve the pick up rate of cotton fiber, is convenient to again cotton fiber and comes off, easy to use.
Another object of the present invention is to provide a kind of mechanical cotton picker that this cotton picking pin is housed, and replaces artificial cotton picking with it, can greatly reduce workman's labour intensity, increases work efficiency, and improves the industrialization level of machine cotton picking.
The object of the present invention is achieved like this, a kind of cotton picking pin, comprise needle body, on the axial periphery face of needle body, uniform interval is arranging some grooves, on axial fin between every adjacent two grooves, all uniform interval is arranging the cotton picking tooth of arranging from syringe needle to backshank, and the evagination wedge angle portion of cotton picking tooth is all near syringe needle.
Cotton picking needle construction of the present invention by all cotton picking crown bights near needle placement, can easily the cotton fiber being wound around on cotton picking pin be shirked to syringe needle direction from backshank like this, effectively avoid occurring that cotton fiber easily adopts the drawback that is difficult for shirking, easy to use.
A kind of mechanical cotton picker that described cotton picking pin is housed, comprise the housing with aspiration suction mouth, inside and outside two ring annular grooves are being set respectively on the two side of housing, between the two side of housing, be upper and lower horizontal interval driving and driven rotating shaft is being set, between driving and driven rotating shaft, around being housed, a circle is oblong rotating band, width between the width of rotating band and housing two side matches, on the housing two side of interior annular groove inner side, a Long Circle flange is vertically being set respectively, on the annular periphery wall of this flange, teeth is being set respectively, between housing two side, be horizontally disposed with some tubulose cotton picking needle stands, the uniform interval, both sides of cotton picking needle stand is arranging coaxially arranged cotton picking pin and is driving bearing pin, in every cotton picking needle stand, be all set with a central shaft by bearing, on central shaft, uniform interval is arranging several bevel-gear setts, each bevel-gear sett drives one to be arranged on the cotton picking pin rotation on cotton picking needle stand by bearing, cotton picking pin and central shaft are perpendicular and be positioned at same plane, the both side ends of every central shaft is all arranging respectively a roller and a gear, two rollers at central shaft two ends lay respectively in said interior annular groove, two gears are meshed with the teeth on the flange of housing two side respectively, drive bearing pin to be connected with said rotating band, between housing two side, be also horizontally disposed with some comb and parallel cotton fibers prior to spinning bars, on every comb and parallel cotton fibers prior to spinning bar, all by the uniform interval of bearing, several comb and parallel cotton fibers prior to spinning ring sets are installed, comb and parallel cotton fibers prior to spinning ring set is slidably matched respectively and is sleeved on each cotton picking pin, and a roller sliding along outer ring groove is being set respectively at the two ends of comb and parallel cotton fibers prior to spinning bar, said suction mouth is positioned at housing upside rear portion, the inside-and-outside ring groove that is positioned at housing front portion is arranged vertically and is mutually close, the upper proceeds posterolateral cell body portion of outer ring groove is near suction mouth, and the radial alignment distance of this cell body portion and interior annular groove is equal in length with cotton picking pin.
When the work of the present invention's machinery cotton picker, drive active rotating shaft to rotate by dynamic power machines such as electromotor or petrol and diesel oil machines, then order about around being contained in master, rotating band on driven spindle turns clockwise from down to up, because the both sides of cotton picking needle stand are arranging respectively said cotton picking pin and driving bearing pin, drive bearing pin to be connected with said rotating band, like this, in the time that rotating band rotates, by driving bearing pin to drive the motion of cotton picking needle stand, every cotton picking needle stand central shaft both side ends is all arranging respectively a roller and a gear, gear is meshed with said teeth, along with the rotation of gear, drive the central shaft in cotton picking needle stand to order about each cotton picking pin rotation by bevel-gear sett, cotton picking pin is in rotation, also along with cotton picking needle stand moves from lower to upper, thereby the cotton fiber in cotton boll is wrapped on cotton picking pin.Because cotton picking needle construction of the present invention is slidably matched comb and parallel cotton fibers prior to spinning ring set is being set on cotton picking pin in addition, can fast and effeciently cotton fiber be shirked like this.
Said suction mouth is positioned at housing upside rear portion, the inside-and-outside ring groove that is positioned at housing front portion is arranged vertically and is mutually close, the upper proceeds posterolateral cell body portion of outer ring groove is near suction mouth, and the radial alignment distance of this cell body portion and interior annular groove is equal in length with cotton picking pin.In the time that cotton picking pin runs to said cell body portion, comb and parallel cotton fibers prior to spinning ring set just runs to the head place of cotton picking pin along with comb and parallel cotton fibers prior to spinning bar like this, shirks the cotton fiber getting off and is sucked in suction mouth by blower fan thereupon.Periodic duty and so forth, can fast and effeciently complete the operation of machine cotton picking.
Advantage of the present invention is, cotton picking pin is parallel distribution, is increased radioactivity more advanced than imported from America cotton picker cotton picking pin, from lower up motion parallel to the ground, test in the ground according to model machine, pick up rate can reach absolutely, and no longer establishes independent de-cotton machine structure, need not spray water, therefore this type can carry cotton cleaner the cotton of adopting is back mixed clearly, simple in structure, cost is low, easy maintenance.
With the present invention's machinery cotton picker, replace artificial cotton picking, can greatly reduce workman's labour intensity, increase work efficiency, improve the industrialization level of machine cotton picking.
