Description

Grapple formula cotton picker

One, technical field: the utility model relates to a kind of cotton harvesting machine, especially a kind of cotton picker with grapple formula picking head.

Two, background technology: cotton harvesting machine generally has the harvesting parts, and gas delivery sections part and cotton collecting part are formed.The development test of more existing small cotton pickers, cotton is manually plucked in imitation, by a cotton picking.There is a kind of small cotton picker to draw cotton suction duct, cotton is inhaled to take off from plant is transported to again the collection hopper by blower fan.This cotton suction duct inhales to bursting forth inadequately fully cotton boll that to pluck effect bad, sucks the branches and leaves chip again easily, reduces Cotton Grade.The wind power transmission device of carrying cotton is inhaled titbit to blowing titbit to a switching mechanism will be arranged the working procedure that collects hopper plucking from cotton plant, this mechanism or complex structure in the prior art, and perhaps broken cottonseed is many, unreliable.Therefore, existing small cotton picker does not reach the practical stage as yet.

Three, summary of the invention: the purpose of this utility model is a kind of grapple formula cotton picker of design, and it plucks reliable, and it is simple that conversion is plucked and blowed in the suction in the course of conveying.Its technical scheme is: be installed with on the frame of road wheel, electric motor driven blower fan is equipped with in the front, and there is diesel generating set at the middle part, and the blower fan back goes out fancy top and connects two collection web casees.Blower fan has individual cylindrical shape Fan casing and square tube shape to go out fancy top.An end has the centrifugal fan impeller on the axle in the cylinder Fan casing, is provided with air regulating board at the air inlet of impeller outside cylindrical Fan casing end face; Connecting separator in the blast fan inner end, separator another side radioactivity is equipped with 4-8 square tube shape air inducing box, the center line of square tube is radial distribution, each air inducing box on the separator is connected to each other near an end of disk center, each tie point is distributed on the same circumference, this circumference is the air inlet of the engine housing other end facing the wind, and is identical with the air inlet size.The aspiration channel that joins with separator one side air inlet extends to Fan casing cylindrical wall outside, and 2-10 suction pipe interface arranged on the aspiration channel, connects grapple formula defloration head by flexible pipe; The terminal barrel of fancy top that goes out of blower fan has one section inclined-plane that section is reduced, and the outlet of band filter screen is arranged on the inclined-plane, guides ground into by fairlead; Blower fan goes out fancy top and there is colored Movable valve two collection web case junctions.Described grapple formula defloration head is to be provided with handle and trigger on the straight tube outer wall of a band elbow.In the elbow outside 3-6 grapple arranged, grapple one end is hinged on the pipe outer wall, and pin joint is equipped with grapple and opens spring, and the crotch of grapple is worn to die from elbow ends; The grapple middle part connects the pull rope towards tube wall, and the pull rope of each crotch is brought together backward along tube wall, joins with trigger again.Go out fancy top and two collection hopper junctions and have colored Movable valve.

This defloration machine effect height, defloration is sticking assorted less, under identical number situation than manually raising the efficiency more than 4 times.

Four, description of drawings: Fig. 1 is the plan structure figure of grapple formula cotton picker.Fig. 2 is the structural representation of grapple formula defloration head.Fig. 3 is the structural representation of blower fan.Fig. 4 is the rearview of separator in the blower fan of Fig. 3.Fig. 5 be among Fig. 4 the air inducing box to view.

Five, embodiment: the overall structure of grapple formula cotton picker as shown in Figure 1.On the frame 12 that has road wheel 6, the blower fan 1 that electromotor 3 drives is equipped with in the front, and there is diesel generating set 8 at the middle part, and the blower fan back goes out fancy top 4 and connects two collection web casees 7.Owing to the rotating speed of engine can change along with load variations, engine directly drives blower fan, inhales and send the air-flow of titbit also can change, and influence defloration machine operate as normal, so adopts electromotor style mechanomotive force.Adopting two collection hoppers is in order conveniently to unload flower at the edge of a field.2-10 suction pipe interface 10 arranged on the aspiration channel 9 of blower fan, connect grapple formula defloration 13 by flexible pipe respectively.Each defloration head is by the hand-held operation of a people, cotton picking.Described grapple formula defloration 13 is to be provided with handle 14 and trigger 15 on the straight tube outer wall of a band elbow 16 as shown in Figure 2.In the elbow outside 3-6 grapple 17 arranged, grapple one end is hinged on the pipe outer wall, and pin joint is equipped with grapple and opens spring 19, and the crotch of grapple is worn to die from elbow ends.There is the pull rope 18 towards tube wall at the grapple middle part, and the pull rope of each crotch is brought together backward along tube wall, joins with trigger 15 again.The cotton boll titbit that the defloration people is burst forth a defloration subtend, cocking make grapple shrink to the elbow center, catch titbit, make titbit break away from the cotton boll shell in pulling back.Unclamp trigger, grapple withdraws from the elbow mouth of pipe, and high velocity air is inhaled titbit to take off immediately and seen off.Described blower fan 1 is as Fig. 3, and it has a cylindrical shape Fan casing and square tube shape to go out fancy top 4.An end has centrifugal fan impeller 20 on the axle 11 in Blower Housing.The air inlet of Fan casing end face is provided with air regulating board 22, and the aperture that changes air regulating board can change the wind-force size.Connecting separator 21 in the blast fan inner end, Fig. 4 is the rearview of separator among Fig. 3, radioactivity is equipped with 4-8 square tube shape air inducing box 24 above it, the center line of square tube is radial distribution, each air inducing box is connected to each other near an end at separator center, tie point is on the circumference, and this circumference is the air inlet of the engine housing other end facing the wind, and is identical with the air inlet size.The aspiration channel 9 that joins with this air inlet extends to Fan casing cylindrical wall outside.Separator is with blower fan cylinder bore separated into two parts, and blast fan one end has less air quantity, is used for outwards carrying titbit.Air inducing box one end air inlet has bigger negative pressure, is convenient to the defloration head and plucks the suction titbit.The titbit of being plucked suction enters in the Fan casing through air inlet, air inducing box, is delivered to blast fan one side by bigger blast, is blown into collection web case 7 through going out fancy top again.Going out fancy top and two collection hopper junctions has colored Movable valve 5, changes valve location and can make titbit enter different collection hoppers.The fancy top barrel that goes out of blower fan has one section inclined-plane, and the fairlead 23 of band filter screen 3 is arranged on the inclined-plane, and fairlead is guided ground downwards into.The cauline leaf disintegrating slag that the defloration head sucks can move along the Blower Housing inwall in the air-flow outside, at last by outside the fairlead derivation machine.
