Description

The slimline cotton picker

Technical field

The utility model slimline cotton picker relates to a kind of artificial free-hand cotton a kind of machinery of adopting that replaces, and belongs to agricultural machinery technological field.

Background technology

Domestic cotton picking since ancient times all is artificial free-hand harvesting, and efficient is low, labour intensity is big.The semi-automatic cotton picker of the hand-held of present domestic appearance can't operate as normal by the cotton fiber winding but still exist machine in the harvesting process.Though large-scale cotton picker tool efficient is high, with high investment, high consumptive material, scope of application limitation are unfavorable for that the whole nation promotes on a large scale.

Summary of the invention

According to the deficiency that present cotton picking technology exists, the purpose of this utility model provide a kind of volume little, make simple, easy to use and use machine can not twined stuck slimline hand-held cotton picker for a long time by cotton fiber.For realizing above purpose, adopt following technical proposal: promptly on the cotton-picker head housing, evenly leave many row's cotton hook needles hole, every row should have porous, both sides respectively be equipped with one with the consistent guide pillar of cotton hook needle hole row number, guide pillar is uniform and smooth, not parallel with the center of circle radius of housing, angled, guide pillar is with spring, cotton hook needle that interfixes and needle stand are by the guide pillar hole alignment guide post on the needle stand, cotton hook needle is aimed at the cotton hook needle hole and is filled in from inside to outside, there is eccentric axis to be installed in the middle of the needle stand, two end cap center, the left and right sides is passed at the axis two ends, the length size of spring is as the criterion nimbly and freely with axis rotation cotton hook needle turnover cotton hook needle hole, put into the bearing of close-fitting in the shell in the two end cap outside, the left and right sides by the axis two ends then, pack into the transition bearing of a close-fitting by the prolongation of left side end cap, the shell of transition bearing is fixed on the support of left side casing, the left end cap prolongation that stretches out support is fixed with belt pulley, the axis that stretch out on the right side is fixed on the support of right side casing, being fixed on the constant-seed motor of casing rear end is connected with belt pulley on the cotton-picker head, the cotton-picker head below is provided with cotton inlet port, the cotton inlet port back lower place is provided with cotton output port, and cotton output port is with the cotton bag of collection.

Owing to adopt the utility model slimline cotton picker of technique scheme made, when the cotton-picker head rotation is plucked, the preceding more than half portion cotton hook needle that contacts with cotton can stretch out the hook cotton automatically, bring cotton into cotton inlet port after cotton hook needle can withdraw automatically, slip into cotton output port behind the defoliating cotton automatically and enter the cotton bag of collection.Owing to adopt inside and outside transition bearing that the left side end cap is extended to outside the chassis bracket, so transmission device enters channel with cotton and separates, overcome the phenomenon that cotton fiber twines stuck machine, adopt constant-seed motor, belt and transition wheel have been reduced, make complete machine lighter and handier, so the cotton picker volume is little, it is simple, easy to use to make, can use for a long time.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples: this machine-operated key member is a cotton-picker head, by cotton-picker head housing (1), guide pillar (2), spring (4), cotton hook needle that interfixes and needle stand (Fig. 5), left and right sides end cap (7) (8), transition bearing (6), belt pulley (5) and have the axis (13) of eccentric wheel (12) to form, have mutual equidistant five-element's cotton hook needle hole (3) on the cotton-picker head housing (1), every row four holes, pore size is as the criterion freely with cotton hook needle (9) turnover activity, both sides, every capable cotton hook needle hole (3) be equipped with one with cotton hook needle hole (3) same center line on guide pillar (2), guide pillar (2) is not parallel with the radius of cotton-picker head housing (1), tilt 20 °, cotton hook needle that interfixes and needle stand (Fig. 5) are by guide pillar hole (11) alignment guide post (2) on the needle stand (10), cotton hook needle (9) is aimed at cotton hook needle hole (3) and is outwards filled in cotton-picker head housing (1), to there be the axis (13) of eccentric wheel (12) to be installed in the middle of five needle stands (10), left and right sides two end cap (7) (8) center is fixed on the housing (1) of cotton-picker head by axis (13) two ends, two bearings of close-fitting are packed in the shell in left and right sides two end cap (7) (8) outside by axis (13) two ends respectively, pack into the transition bearing (6) of a close-fitting by the prolongation of left side end cap (7), the shell of transition bearing (6) is fixed on the support of left side casing, at the fixing upper belt pulley (5) of left side end cap (7) and the prolongation that stretches out chassis bracket, the axis (13) that the right side is stretched out is fixed on the chassis bracket of right side again.The centering error of eccentric wheel (12) is 3.5mm, the length of cotton hook needle (9) is that 3.5mm is as the criterion to reach housing (1) the longest outer part, because of the centering error of eccentric wheel (12) is 3.5mm, so cotton hook needle (9) was condensed to zero when cotton-picker head forwarded another side to, because of guide pillar (2) and housing (1) center radius tilt 20 °, so the cotton hook needle (9) that cotton-picker head stretches out also tilts 20 °, because of adopting inside and outside two transition bearings (6), so belt pulley transmission devices such as (5) is all in the chassis bracket outside, should the longest position forward with cotton hook needle (9) in the time of fixedly, the inclination angle is downward, the belt pulley (5) in left side is connected with constant-seed motor (14) by belt (15), the cotton-picker head below is provided with cotton inlet port (16), cotton inlet port (16) back lower place is provided with cotton output port (17), and cotton output port (17) is with the cotton bag of collection (18).

The slimline cotton picker that adopts technique scheme to make, when adopting cotton, constant-seed motor (14) is rotated the back and is made cotton-picker head housing (1) rotation by transmission device, the cotton that the fore-end contact is left, downward-sloping and cotton hook needle (9) that grow cotton-picker head housing (1) advances cotton inlet port (16) with the cotton hook, because of the latter half of cotton hook needle of cotton-picker head (9) is condensed to zero, so defoliating cotton falls into the cotton bag of collection (18) to cotton output port (17), because of belt pulley transmission devices such as (5) all outside chassis bracket, entering channel with cotton separates, so can not twined by cotton fiber, because of adopting constant-seed motor (14), reduced belt, transition wheel, so volume is littler, this slimline cotton picker volume is little, make simple, easy to use, can use for a long time.
