Description

Cotton picker blowing tube

Technical field

The utility model relates to cotton picker, particularly relates to the blowing tube of cotton picker, belongs to agricultural machinery.

Background technology

The picking season property of cotton is strong, generally adopts cotton by manual, and effect is low, the cotton region difficulty that recruits workers.Thereby people have designed various cotton pickers, and the primary structure of existing cotton picker comprises power, adopts cotton system and blowing system, and described power is blower fan; Describedly adopt cotton system and suck by blower fan, because cotton is how long below leaf, and the leaf of cotton is easy to fragmentation, accompanies a large amount of leaves so inhale the cotton that comes; Described blowing system mainly is the blowing tube, by the blowing tube cotton is separated with leaf.Two or three cylinders are installed in the prior art blowing tube usually, on cylinder outer wall, be shaped on and roll thorn, be used for removing foreign material such as cotton leaf that cotton carries, boll hull, the 26S Proteasome Structure and Function of described two or three cylinders all is the same, when the part cotton is adsorbed on the filter screen of an inwall, can't brush down, and impurity also can stick on top, of long duration can accumulation, influence the blower fan effect, and the device that does not keep out the wind, when blower fan sucks cotton, can produce and pour in down a chimney, blow cotton, cotton leaf and boll hull etc. to such an extent that fly in the bucket civil strike, be not easy deposition, cleaning is trouble very.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, provides one to grow cotton and suck and carry, and avoids wind direction to pour in down a chimney, scutching cotton is effective, and is simple in structure, low cost of manufacture, cotton can be separated with boll hull with cotton leaf, make the clean cotton picker blowing tube of cotton.

The technical scheme of the utility model cotton picker blowing tube is: comprise cylindrical shell, cylindrical shell is shaped on air inlet, mouth-piece, cotton output port and leaf outlet, air inlet has ventilating duct in the filter screen, by the blower fan air draught, the separator of cotton and leaf is installed in cylindrical shell, at cotton output port little blower fan is arranged, it is characterized in that described separator comprises is divided into defeated cotton chamber in the cylindrical shell, keep out the wind chamber and separation chamber, three Room interconnect, air inlet and mouth-piece are in defeated cotton chamber, and cotton impeller is failed in defeated cotton indoor installation, and described defeated cotton impeller comprises two end cap, center-wheel arbor and be installed in support and blade on the center-wheel arbor, blade is shaped on air vent; The impeller that keeps out the wind is installed in the chamber of keeping out the wind, and the described impeller that keeps out the wind comprises keep out the wind axle and the leaf that keeps out the wind that is installed on the axle that keeps out the wind, and there is end plate at a two of keeping out the wind; Install to separate roller in the described separation chamber, described separation roller comprises Roller Shaft, and there is cover plate at Roller Shaft two, and Roller Shaft is installed round cylinder outward, and the circle cylinder outer wall has the separation gear hobbing, and center-wheel arbor, keep out the wind axle and Roller Shaft are driven by power.

The utility model discloses a kind of cotton picker blowing tube, the blowing tube is adopted the cotton that comes to cotton picker by blower fan (big blower fan is installed before the blowing tube) air draught and is sucked the blowing tube, in the blowing tube, cotton is separated with leaf, cotton at first arrives defeated cotton chamber by mouth-piece, promote cotton by blade after the defeated cotton indoor defeated cotton wheel rotation, blade is shaped on air vent, so cotton is played suction-operated, after blade is constantly shifted the cotton that sucks onto the chamber of keeping out the wind, continue cotton is down pushed away by the leaf that keeps out the wind, the leaf that keeps out the wind promotes cotton on the one hand, blocks down the air port on the other hand, avoids following wind-fall to irritate.Leaf pushes the separation chamber to cotton by keeping out the wind, install in the separation chamber and separate roller, separate the roller outer wall separation gear hobbing is arranged, separate roller by rotating, by separating gear hobbing cotton is played fluffing action, make foreign material such as cotton leaf in the cotton and boll hull under the effect of little blower fan, get rid of the blowing tube, by little blower fan pure cotton is released from cotton output port simultaneously.

The utility model cotton picker blowing tube, the described hairbrush fixed strip of on the blade of defeated cotton impeller, installing, the two ends of hairbrush fixed strip are fixed on the support, on the hairbrush fixed strip, be shaped on hairbrush, hairbrush contacts with filter screen, had hairbrush can be adsorbed on the blowing tube inwall filter screen cotton or impurity, dust brushes down, hairbrush soft with blowing tube and filter screen in wall friction, blowing tube and filter screen inwall can not ground away, and cleaning effect is good.The head of the described leaf that keeps out the wind at the impeller that keeps out the wind is installed diaphragm seal, and diaphragm seal matches with cylinder inboard wall, and diaphragm seal and blowing tube inner wall sealing prevent to pour in down a chimney on the wind direction of blowing tube bottom.Described diaphragm seal material can be that rubber or plastics or leather are made, and material softness reduces blowing tube inner wall abrasion.The described grizzly bar that is shaped on leaf outlet, grizzly bar can separate with foreign material such as boll hulls cotton leaf with cotton, prevent that cotton from falling into leaf outlet.The power of described center-wheel arbor, keep out the wind axle and Roller Shaft is driven by upper and lower chain by motor, and last chain connects the center-wheel arbor and the axle that keeps out the wind, and lower chain drives keep out the wind axle and Roller Shaft, and three axles are driven behind reducing gear by same motor.
