Description
Technical field
The invention belongs to corn harvesting machine and processing technique field, the processing method being specifically related to a kind of corn husking roller and the peeling rollers using the method to process.
Background technology
Corn is one of five generalized grain crops.China's corn planting gross area totally 2,450 ten thousand hectares, accounts for 25% of national plant of grain crops area; Gross annual output amount reaches about 1.27 hundred million tons, accounts for 27% of national total output of grain.Current China has formed three large Maize Production districts, and one is northern com district, comprises three provinces in the northeast of China, Inner Mongol, Hebei Province etc., and sown area accounts for 40% of the whole nation; Two is Maize Regions that the Yellow River and Huai He River is flat, comprises the ground such as Shandong, Henan, Jiangsu, and sown area accounts for 25% of the whole nation; Three is Maize Regions, southwestern hills, comprises the area such as Yunnan, Guizhou, and sown area accounts for 15% of the whole nation.If calculate by 50% machine yield, the whole nation needs maize harvesting machine lO more than ten thousand.And reality be China's corn machine yield less than 2%, level received by the machine well below wheat 70% and paddy rice 20%.
In China's Maize Production process, plough, harrow, broadcast, manage and generally achieve mechanization or semi-mechanization operation, have the facility of more perfect Multiple Type, but mechanized harvest problem not yet solves so far.The harvest corn operation of developed country realizes mechanization already, and the special ceding of Taiwan of corn joined by facility of its application mainly corn combine or large-scale grain combine, disposablely completes harvesting, harvesting, peeling, cleans fruit ear operation.Because China's corn is most by peasant household's Cultivate administration voluntarily, land management is not concentrated, and peasant household's purchasing power is limited, and large-scale united reaper can't large scale application within the quite a long time.Except minority large-scale farm part is tried out except corn combine harvesting corn, national harvest corn almost adopts manual work.Artificial reaping corn operation labor intensity is large, and efficiency is low, takies a large amount of man-hour, but moisture is comparatively large when wherein most distinct issues are corn ear results, its bract hygroscopicity is very strong, and seed can not aeration-drying in time, can cause mildew and rot very soon, the phenomenons such as rotten or germination.Because manual peeling efficiency is low, on average can only complete 0.07 hectare operation for each person every day, and labour intensity is large, very arduous, every harvest season, because fruit ear can not the peeling in time and loss that causes is quite large.Solve corn ear husking problem and become the key issue improving corn product quality, reduce loss, liberating rural labour.
Peeling machine core component is apparatus for peeling off, and the material of conventional peeling rollers has cast iron and rubber two kinds.Apparatus for peeling off has the combinations such as cast iron roll one cast iron roll, cast iron roll one rubber rollers, cast iron roll one cast iron roll and rubber rollers.A cast iron spiral discaling roll and rubber helical (petal rubber) peeling rollers pairing is adopted to use, the centre-to-centre spacing a-66.75ram of two pair rollers, and two pair rollers form a flute profile, general employing two to or four pair rollers. for increasing the pressure of corncob and roller, above peeling rollers, be furnished with two groups or three groups of suppressors.
Peeling rollers is primarily of the rigidity peeling bitch composition at roll body, the helical raised being arranged at roll body circumferential surface, partition and roll body circumferential recess position, and its roll body and helical raised are rigid body; The setting of sunk part partition can increase the peeling area of peeling machine.
According to material therefor, peeling rollers can be divided into cast iron roll to cast iron roll, cast iron roll to various combinations such as rubber rollers.Cast iron roll is easily manufactured, cost is low, wearability is good, long service life, can install again and draw leaf device, and fruit ear peeling effect that is tight to bract, high humidity is better.Its shortcoming is that Grasping skill is little, and reduces with degree of wear aggravation.Because the coefficient of friction of rubber is larger than the coefficient of friction of metal, so its Grasping skill and break the ability that bract and fringe handle link and strengthen, walnut hulling rate is high, again because rubber is flexible, its seed damage rate is lower, but is greater than cast iron roll due to the axially-movable resistance of corncob, and therefore its productivity ratio is lower.In view of the foregoing, peeling parts should select cast iron roll and rubber rollers to combine and the peeling rollers of grooved arrangement.Its structure is: iron roll surface is welded with spiral reinforcement, shells bar at the other rubber of installing of reinforcing bar; Rubber is installed in helicla flute and draws leaf device. to increase grasp force, reduce the damage to corncob; Spiral is divided into 3 parts, and anterior lead angle is little, and take second place in middle part, rear portion is larger.
Its working (machining) efficiency of corn husking roller of normally used full elastomeric material is low, because its roll surface is with spiral ridge, and every root roller has 3 joint spiral rubber roll serial connections form, its concatenation process is manually.And the peeling rollers of elastomeric material is due to the restriction of its material, in use quick abrasion, have influence on the operating efficiency of peeling machine.
Summary of the invention
The processing method that the technical problem to be solved in the present invention is to provide high, the anti abrasive corn husking roller of a kind of production efficiency and the peeling rollers using the method to process.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of processing method of corn husking roller, comprises the following steps:
S1: pipe embryo is carried out destressing heat treatment;
S2: utilize chain drawbench and the first supporting mould, first time cold-drawn is carried out to pipe embryo, the outer surface of pipe embryo processes many continuous print spiral ridges;
S3: utilize chain drawbench and the second mould, the pipe embryo cold-drawn being gone out to spiral ridge carries out second time cold-drawn, along pipe plumular axis to processing multiple groove on spiral ridge.
Wherein, in described step S1, after pipe embryo destressing heat treatment, utilize head rolling machine first one end undergauge of pipe embryo to be made it to enter mould, and after machining, termination is excised.
Wherein, in described step S2, be provided with the hydraulic means of pipe embryo jacking first mould in the charging side of chain drawbench spindle hole.
Wherein, in described step S2, rotated, by the power drawing pipe embryo of draw-off gear by the motor and chain-driving first mould being installed at chain drawbench spindle hole top.
Wherein, in described step S2, the supporting power of chain drawbench is 40kw, and the linear velocity in Cold Drawing Process is 7-8m/min, and the first mould rotating speed is 40r/m.
Wherein, in described step S3, the second mould is static not to be turned, and chain drawbench is by power drawing pipe embryo, and drawn wire speed is 8-9m/min.
Present invention also offers a kind of corn husking roller, comprise roll body outer surface having many continuous print spiral ridges, every bar spiral ridge axially all has multiple groove along roll body.
Wherein, the number of described spiral ridge is 4 to 7.
Wherein, the number of described spiral ridge is 5.
Wherein, the number of the groove that described spiral ridge one is circumferential is 40.
The beneficial effect adopting technique scheme to produce is: the processing method of peeling rollers of the present invention is undertaken by twice cold-drawn operation, and production efficiency is high, can realize batch production, account for and have an enormous advantage in market competition from now on.Utilize the peeling rollers that the inventive method processes, the spiral ridge on pipe embryo outer surface can be convenient to fruit ear and glide along the line, adds the teeth groove on peeling rollers, increases the frictional force between peeling rollers and bract; And what whole root timber material all adopted is A3 steel part, there is wear-resistant, that utilization rate is high advantage.
