Description

Light miniature rice combine-harvester

Technical field: the utility model belongs to agricultural mechanical field, is specifically related to a kind of light, split combination, the light miniature rice combine-harvester of energy a tractor serves several purposes.

Background technology: present domestic and international large-scale combine, though technical performance, harvesting efficiency are high, the zone, paddy field, vast hills of China south not being carried out as yet the garden farming transformation still can not enter operation, the production development needs are far from suitable.

The middle-size and small-size combine developed in succession of various places in recent years, concentrate on area, south, Hunan, as representative types such as the electric 4L2-104 type of Yueyang China, Changde Guan Bao board 4LZ-1.5 type, Yiyang 4L-50 type, Ziyang 4L-120 types, generally be the fringe harvesting of raising, the residual seedling standing grain root and stem of certain plants is too high, and body is still heavy, structure is complicated, situations such as mating power is big, and work done is single are that limitation is available basically.

Summary of the invention: this is suitable for novel development purpose is comprehensive domestic and international similar type, select the essence, and I former obtain on patent (patent No. 99249645.4) item base further to transform improve, make its structure, performance, economic indicator, applicable elements reach the desirable requirement of peasant, thereby alleviate peasant's labour intensity, improve productivity effect, to quicken the Tendency of Agricultural Machinery in China development in an all-round way, satisfy peasant's of new generation eager desire and a kind of light miniature rice combine-harvester is provided.

Technical solutions of the utility model are to adopt split modular structure, and the chassis is the haulage gear of independently walking, can be supporting with the two-wheel ploughing and leveling machine for paddy field, and can connect and hang trailer motion and equipped harvesting, threshing system.Adopt up and down two groups of blade row segmentation harvestings, based on partly feeding operation principle, realize its best harvesting effect.By Diesel Driven, hand steered walking is driven.Mainly by chassis assembly, cropping system and transmission system three major parts are formed.

The utility model chassis is by frame, gearbox, road wheel, diesel engine, operating grip mechanism, mud is drawn composition one independent work done integral body such as pallet, gearbox is contained in above the central rack girder, two walking rubber tires (the iron teeth wheel is changed in the paddy field) are housed on the semiaxis of the output shaft of gear-box left and right sides, mud is drawn pallet and is connected in the frame rear portion, forms three points of contact, keeps the chassis even running.Diesel engine is contained in mud and draws above the pallet, by belt pulley drive that transmission device makes soon in the gearbox, slow, advance, the gear shift of backward gear, needed speed during the realization work done.On the gearbox power shaft friction clutch is housed, control starts clutch.Two cover jaw clutches are housed about output shaft,, realize that it turns to by shifting fork device, light reliable.This chassis can be equipped with ploughing equipment and connect and hang the trailer transportation, has realized a tractor serves several purposes, has reduced the peasant and has purchased the machine input.

The utility model cropping system is that collection harvesting, threshing, screening, defeated paddy, packed mechanism and the relevant driving-chain of harvesting, wheel based part and bucket body drive shell composition one are independently whole; its work done program is to receive standing grain by the place ahead to roll the rice standing grain pulled out to cut to the fringe blade row mouth place of raising and cut, and will cut the standing grain fringe input separating mechanism that cuts by the spiral roll of dress in the harvesting bucket in succession and carry out threshing.Straw cane stage casing is cut and is cut by being contained in standing grain-cutting stump-knife row below the harvesting bucket, and dogstail directly is dispersed in ground, does not enter the harvester-thresher structure, the handling capacity that so just greatly reduces receipts, takes off system's straw.Not only load is light, can also satisfy the low agro-farming requirement of the residual standing grain root and stem of certain plants.

The utility model threshing roll is formed an annular tooth by the longitudinal and transverse tooth bar of many rows and is rolled the end and be equipped with and blow standing grain Mao Fengye, and Lysimachia sikokiana helical arc muscle is equipped with in threshing barrel inwall top, the zigzag horizontal stripe is equipped with in the both sides, middle part, stirs the millet straw good separating effect through high speed rotating.Grain behind the classical prescription diagrid net filtration falls into spiral conveying groove again.Carry the lifting pack by auger conveyor and tooth plate conveyer belt.

The utility model bucket body drive shell all adopts the manufacturing of special wear-resisting glass fibre reinforced plastic material, has in light weight and corrosion resistant advantage.

The spiral roll of the utility model is taken off tears and is rolled, and the defeated paddy device two-end part of spiral is equipped with to be prevented twining careless arc muscle plate washer, has overcome straw axis fault.

The transmission of the utility model cropping system, be to drive axle (F) running of passing a bridge by sprocket wheel on the gearbox power shaft (A) and chain to drive each work done of cropping system respectively, its axle (F) left end of passing a bridge is equipped with friction clutch, the rotation of controlled cropping system or stop.

The lifting height debugging mode of the utility model harvesting bucket is to realize by a cover small and exquisite worm screw, rope hoisting mechanism and the link plate that is fixedly connected, and is simple in structure, the location is reliable, only needs the jog handle, just can just realize stepless adjustment to the rice standing grain.

That the utility model split combining structure has is reasonable in design, realize easy accessibility not upsetting each overall structure, complete machine heavily is 252 kilograms, be divided into trisome, its weight is respectively: 60 kilograms of diesel engines, the harvesting assembly is 95 kilograms, the chassis is 97 kilograms, and two people lift fortune can be narrow on the rural area road, slope light walking on the rugged trail on foot.The connection advanced design of trisome, reasonable, diesel engine is opened the mechanism location, while tightening belt, the combination of cropping system assembly and walking chassis assembly with the employing insertion chute lock that connects of underframe, the employing activity connects link plate, accurate positioning, connects reliable, lifting freely.The split combination of three big parts does not need any instrument, can finish in five minutes.

The utility model has following main feature according to above-mentioned design technology project manufacturing:

1, in light weight, volume is little.

2, mating power little (6 horsepower diesel) energy consumption is low.

3, compact conformation, reasonable, split combining structure easy accessibility (can finish in five minutes) has been saved unproductive time.

4, operate steadily, safe and reliable, operate light.

5, moulding is low, work efficiency height, and energy a tractor serves several purposes, good economical benefit.

The utility model improves perfect with reference to my former Patent project " removable combined small-sized rice combine ".Therefore, with current comparison of the same type, it has in light weight, and is simple and reasonable for structure, moulding is low, and maintenance is moved conveniently, and energy consumption is low, and work done is effective, operates excellent characteristics and easy disassembly such as light, the novel designs of a tractor serves several purposes, perfect Practical Performance.
