Description
Technical field
The utility model relates to a kind of cotton-picker head of small cotton picker.
Background technology
Small cotton picker is a kind of farm machinery of being badly in need of very much in China's agricultural production, and the economy of each cotton growing area is had very significant meaning.But that is that all right is ripe at present most small cotton pickers, rests on the experimental stage, do not have really can extensive use in agricultural production product.The major technology difficult point that present this class machinery is difficult to large-scale promotion concentrates on the following aspects:
(1) picking efficiency.Adopt cotton by hand according to qualification and working strength difference, its efficient uses its picking efficiency of small cotton picker should reach 120Kg～300Kg/12 hour generally at 60Kg～120Kg/12 hour, just can embody its economic benefit.
(2) percentage of admixture of cotton picking.Its percentage of admixture of cotton that small cotton picker is plucked must reach manual and adopt the cotton level that equates, otherwise can not embody its economic benefit equally.
(3) stream time of cotton picker and reliability.Adopt and be generally three months cotton season, working time every day is 12 hours, the minimum failure free time of a small cotton picker 1080 hours is (if be 2 years projected life so, then minimum failure free time 2160 hours), and its power source must be able to guarantee to provide every day continuous firing 12 hours power.
(4) Cao Zuo convenience.The working time of 12 hours every days for the operator, is a very arduous job, small cotton picker must can reduce operator's labour intensity, if machine is too heavy when improving picking efficiency, perhaps complicated operation then can lose its use value.
Some cotton picker adopts blower fan directly to draw the operation principle of cotton in this area, and more typical example is ZL200520008820.1, ZL200520017070.5, ZL94208150.1 etc.This class cotton picker must adopt two-stroke or four-stroke gasoline engine, to guarantee enough big power of fan, produces enough big blast at cotton suction duct, can draw cotton smoothly.The problem of its existence has the following aspects: 1, petrolic service life.Can not satisfy one and adopt cotton season minimum failure free time 1080 hour requirement generally at 200-300 hour the no-failure life of two-stroke or four-stroke gasoline engine.2, too powerful cotton suction duct wind-force can be the most economic environmental protection with cotton leaf of boll hull and the dc source of blower fan power source employing now, but the working time of dc source is very limited, we will give full play of the advantage of dc source, just must improve the operating efficiency of equipment by fair means or foul, reduce power consumption under the prerequisite of practical effect reaching as far as possible.
The cotton formula cotton picker of a lot of pure suctions is arranged now, and not only volume is big, also will consume a large amount of energy.Because excessive wind-force can suck in the collection hopper in the lump being distributed in cotton impurity on every side in a large number, removes impurity mechanism though added in some design, effect is still not too obvious.The nearly section time machinery also occurred and has taken off the product that the cotton machine of following the wind send cotton knot to close, and can occur cotton in actual use and be entangled in cotton-picker head portion, or cottonseed is stuck between doffing roller, and cotton-wool is wrapped on the roller axle.It is key in whole picking head design that these problems fully expose the roller design.
