Abstract

The utility model relates to a miniature corn harvesting machine, and belongs to agricultural machinery. The miniature corn harvesting machine comprises a harvesting platform mounted in front of a tractor body, a lifter, a peeler and a storage device. The harvesting platform consists of a harvesting platform frame, a harvesting platform main shaft, a transmission case, a snapping roll, a helical guide rod, a slide bar hopper and a knife shaft. Lower inclined top inducers are arranged on two sides of the harvesting platform; a lower inclined top inducer is mounted on the slide bar hopper; a packing auger is arranged behind the slide bar hopper; the harvesting platform is connected with a hydraulic lifting arm behind the tractor body through a steel wire rope after bypassing a pulley on the harvesting platform support frame; a tensioner is arranged on the steel wire rope; a support frame is mounted at the rear part of the tractor body in the storage device; a winch is arranged on the support frame; and the steel wire rope passes through the winch and the pulley and is connected with a bar storage hopper. By adopting the structure, the grain damage rate is smaller than 1 percent and the panicle damage ratio is smaller than 1 percent; the bar storage hopper is a lift type; the lift type bar storage hopper is manually or electrically operated through the winch, only lifted during the loading process and positioned at the lowest position when in operation. The miniature corn harvesting machine has low center of gravity, is hard to generate overturn, and facilities the operation on mountains and sloping fields, thereby enlarging the operation of the corn harvesting machine.

Description

The small-sized corn reaping machine

Technical field

The utility model relates to a kind of farm machinery, is a kind of maize harvesting machine specifically.

Background technology

Existing maize harvesting machine is because structural design is unreasonable, in use, for excellent fringe reversal of the natural order of things occurring, excellent fringe point enters between snapping bar rolls, cause and hinder the high problem of grain rate and can not handle, hinder grain rate height, not only influence utilization percent then, grain then is damaged in the ground, the grain that abandons coming year in the ground is longer, be exactly that so-called captive gives birth to the crops, lack the seed advantage, certainly will cause underproduction next year; The storage device height of maize harvesting machine is certain in addition, can not lifting, be not suitable for mountain region, hillside fields operation.

Summary of the invention

In order to solve the problem of above-mentioned existence, the utility model provides a kind of minimizing to hinder the grain rate, the liftable small-sized corn reaping machine of storage device; The purpose of this utility model is achieved through the following technical solutions: the small-sized corn reaping machine, comprise the ceding of Taiwan that is installed in tractor body the place ahead, elevator, the storage device of flaying machine and dilatory After-Body, it is characterized in that: ceding of Taiwan main shaft is installed on the header frame, ceding of Taiwan spindle pulley is connected by belt with the diesel engine belt pulley, gearbox is installed on header frame, the end of four output shafts of gearbox is equipped with snapping bar, front end at the both sides snapping bar connects spiral guide rod, be shaped on declivity point persuader in ceding of Taiwan both sides, the rod bucket that slips is installed in the header frame middle part, slipping rod bucket the place ahead installation declivity point persuader, slide rod bucket back is provided with auger, the ceding of Taiwan is by the pulley on the ceding of Taiwan support, steel wire rope is connected with the hydraulic pressure landing arm of dilatory After-Body, is provided with stretcher on steel wire rope; Storage device is that support is provided with winch at dilatory After-Body mounting bracket, steel wire penetrating winch, pulley and deposit rod bucket and be connected.

The beneficial effects of the utility model: the utility model adopts said structure, and during the work of declivity point persuader, paracone can be picked up the crops that ground is not arrived in lodging apart from alley platform 200～300mm.Become 30 °～45 ° front bevels with ground at vertical plane, become 30 ° of left and right sides angles with spiral guide rod at horizontal plane, middle persuader both sides highest point and two spiral guide rod axial lines form on same plane induces the passageway, long 30～50mm, two side elevations of middle persuader and the spiral bar distance 3～5mm of spiral guide rod are after stalk passes through the passageway, the rod fringe enters slide rod bucket back bevel immediately, guarantees that stalk passes through in the passageway, and excellent fringe slips on the persuader inclined-plane.Because of two snapping bars become to tilt to place, stalk enters roll clearance, grinds in the process excellent fringe downwards at two snapping bars and is seized down, falls into to slip the fringe bucket.Hang upside down excellent fringe point and seldom have an opportunity to enter between snapping bar pricks, corncob falls into to slip and enters auger, elevator behind the rod bucket and be sent to flaying machine again and strip off the skin, and puts into elevation (over-and-under) type afterwards and deposits the rod bucket, deposits the rod bucket and mentions under winch rotates, and opens to deposit rod bucket downward swing door and realize entrucking.Cutter drives high speed rotating by ceding of Taiwan spindle pulley, with ledger-plate cutting chaffy corn stalk.Once finish corn picker, strip off the skin, entrucking, straw-returning.The grain damage ratio is hindered the fringe rate less than 1% less than 1%.Per hour gather in the crops 3～4 mu.Hydraulic pressure landing arm is a power behind the employing single cylinder tractor with small four wheels, pass through steel wire rope, the pulley pulling ceding of Taiwan, support pivot pin on ceding of Taiwan support rotates, when the landing arm lifts, the ceding of Taiwan is also lifted, and the belt between diesel engine belt pulley and the ceding of Taiwan driving shaft belt pulley shortens because of ceding of Taiwan rise distance of shaft centers, realize the separation of ceding of Taiwan power transmission, replaced clutch and hydraulic jack.Deposit rod bucket and be elevation (over-and-under) type, by winch manually or the electric control lifting deposit the rod bucket, just rise during entrucking, deposit the rod bucket during operation at the low level place, center of gravity is low, is difficult for overturning, and is beneficial to mountain region, hillside fields operation, has enlarged the job area of maize harvesting machine.
