Abstract

The utility model relates to a portable cotton picker which is operated by one hand. A motive power of the cotton picker is fingers. The utility model is mainly composed of three parts of a cotton picking part, a transmission part, and a cotton containing box. When the utility model is used, a grip is gripped by the hand, a cotton picking position is contacted on the cotton needs picking, a forefinger and a middle finger respectively toggle a toggling handle, a rotary motive power is produced, and an upper conveying belt and a lower conveying belt are rotated correspondingly. When a cotton picking tooth is conveyed on the cotton picking position following the conveyer belts, an external tooth tip points to the rotation direction, inserts the cotton, and picks off the cotton. Subsequently, an angle is rotated, the external tooth tip faces away from the rotation direction and conveys the cotton in the cotton containing box, and a cotton picking procedure is finished. The utility model has simple structure and flexible operation. Work efficiency can be raised obviously and labor intensity can be reduced.

Description

Portable cotton picker

The utility model relates to a kind of portable cotton picker tool.

Cotton is the very high crops of a kind of economic benefit, also is a kind of important light industry raw material, and it and people's life is closely bound up.The cotton picker tool that uses is to utilize air-breathing principle to pluck cotton large-scale self-propelled or drawn cotton picker at present, it is very high that this machinery is plucked cotton efficient, but have two problems to need to solve: the one, owing in plucking cotton operation, damaged cotton plants, influence the growth of later stage cotton plant and blooming of cotton boll, reduced output of cotton.The 2nd, owing to dried branches and leaves and dust are sucked in the cotton when plucking cotton, reduced the quality of cotton.Therefore, cotton picking still relies on people's craft to go to finish so far.

In view of the problem that prior art exists, the purpose of this utility model is that a kind of usefulness of design is plucked the portable cotton picker that cotton tooth is plucked cotton.

Portable cotton picker mainly divides plucks cotton part, running part and cotton-containing box three parts.Pluck cotton part by pluck cotton tooth, up and down conveyer belt, up and down the conveyer belt driving wheel, conveyer belt follower, left and right sides sidewall are formed up and down.Plucking cotton tooth middle part has perpendicular axle, will pluck cotton tooth and be divided into internal tooth and external tooth, and four lines is plucked the uniform branch of cotton tooth on conveyer belt at least, plucks cotton tooth axle and is horizontally installed in the conveyer belt interlayer, make pluck cotton tooth can longitudinal oscillation.Conveyer belt driving wheel and follower are made up of axle, wheel, mistake teeth groove, the width of crossing teeth groove equates, quantity is with to pluck cotton tooth line number identical, the conveyer belt follower cross teeth groove deeply less than the distance of plucking crown and conveyer belt in the cotton tooth, the conveyer belt driving wheel is crossed the dark in the distance of plucking cotton tooth and conveyer belt of teeth groove, two groups of bearings is arranged on the sidewall of the left and right sides and two groups of conveyer belt masters, passive wheel shafts cooperate up and down.That conveyer belt is enclosed within is main, rotate with driving wheel between the sidewall of the left and right sides on the follower, each row plucks that cotton tooth is main with it, on the follower the teeth groove center corresponding.Running part is by conveyer belt sprocket gear up and down, transmitting gear, stir the handle gear, stir handle, stir arbor, stir the handle support, handle, the arm bandage is formed, its compound mode is: sprocket gear is fixed on separately one of the drive sprocket axle up and down, stirring handle at least four is fixed on uniformly respectively and stirs on the arbor, stir arbor and stir the handle bracket bearing and cooperate, stirring the handle gear is fixed on stir arbor one and cooperates with travelling gear, travelling gear cooperates with sprocket gear up and down, handle with stir handle support one, stir the handle support and be fixed on the cotton-containing box, the arm bandage is contained in cotton-containing box top.Except that conveyer belt and arm bandage, all available engineering plastics casting of all the other each members also can be made with metal material or other material.

During use, hand passes from the arm bandage, catch handle, cotton picking mouth is touched on the cotton to be plucked, stir handle to palm of the hand direction respectively with forefinger and middle finger, produce rotary power, power is by stirring the handle gear, travelling gear, the conveyer belt sprocket gear, driving wheel relatively rotates and (adjusts gear ratio about making, can obtain required rotating speed), be enclosed within main up and down, conveyer belt on the follower is along with relatively rotating, during plucking cotton tooth and walk to follower on the conveyer belt, internal tooth is stopped by passive wheel shaft in follower is crossed teeth groove, stop to travel forward, and external tooth moves forward, make and pluck the cotton tooth outer point sensing direction of motion, and become movement in a curve by rectilinear motion, at this moment, the contact site of plucking cotton tooth and conveyer belt and passive wheel shaft forms two strong points, inserts in the cotton when plucking cotton tooth, just produce the cotton ability of plucking, in follower rotates, cotton is being taken, after going to 180 degree, become rectilinear motion by movement in a curve, internal tooth breaks away from passive wheel shaft, the internal tooth strong point disappears, owing to the resistance of institute's piching cotton in the cotton-containing box course of conveying, pluck cotton tooth and change angle, outer point is the direction of motion dorsad, when walking to driving wheel, internal tooth does not reach drive sprocket axle in driving wheel is crossed teeth groove, and it is constant to pluck cotton tooth angle degree, can not take the cotton of sending into cotton-containing box out of cotton-containing box, finish the cotton process of plucking.It is simple in structure, light, has both guaranteed to pluck cotton amount, output, has also improved operating efficiency, has reduced labour intensity, and the national conditions of suitable China labour abundance.
