Abstract

The utility model discloses a corn peeling roller which comprises a roller body. A plurality of continuous spiral beads are arranged on the outer surface of the roller body, and a plurality of grooves are formed on each spiral bead along the axial direction of the roller body. According to the corn peeling roller, the spiral beads which are arranged on the outer surface of the roller body can enable cluster edge lines to slide downwards conveniently, tooth grooves on the peeling roller are further additionally arranged, the force of friction between the peeling roller and a bract is increased, so that peeling is easy in the working process of the peeling roller, and the rate of complete peeling of a peeling machine can be improved. Furthermore, the whole piece of material is made of an A3 steel piece, and therefore the corn peeling roller has the advantages of being abrasion-resistant and high in usage rate.

Description

A kind of corn husking roller

Technical field

The utility model belongs to corn harvesting machine and processing technique field, is specifically related to a kind of corn husking roller.

Background technology

Corn is one of five generalized grain crops.Totally 2,450 ten thousand hectares of China's corn planting gross areas account for 25% of national plant of grain crops area; The gross annual output amount reaches about 1.27 hundred million tons, accounts for 27% of national total output of grain.China has formed three large Maize Production districts at present, and the one, northern Maize Region comprises three provinces in the northeast of China, Inner Mongol, Hebei Province etc., sowing area accounts for 40% of the whole nation; The 2nd, the Maize Region that the Yellow River and Huai He River is flat comprises the ground such as Shandong, Henan, Jiangsu, and sowing area accounts for 25% of the whole nation; The 3rd, southwestern hills Maize Region comprises the areas such as Yunnan, Guizhou, and sowing 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 is that China's corn machine yield is less than 2%, well below the machine receipts level of wheat 70% and paddy rice 20%.

In China's Maize Production process, plough, harrow, broadcast, manage and generally realized mechanization or semi-mechanization operation, the facility of more perfect Multiple Type are arranged, but the mechanized harvest problem solves not yet so far.The harvest corn operation of developed country realizes mechanization already, and the facility of its application mainly are that corn combine or large-scale grain combine are joined the special-purpose ceding of Taiwan of corn, disposablely finishes harvesting, harvesting, peeling, cleans the fruit ear operation.Because China corn overwhelming majority is by peasant household's Cultivate administration voluntarily, land management is not concentrated, and peasant household's purchasing power is limited, and large-scale combine can't large scale application within the quite a long time.Except the large-scale farm of minority part corn combine harvesting corn on probation, national harvest corn almost adopts manual work.Artificial reaping corn operation labor intensity is large, and efficient is low, takies a large amount of man-hours, but moisture was larger when wherein distinct issues were the corn ear results, and its bract hygroscopicity is very strong, in time aeration-drying of seed, can cause very soon mildew and rot, the phenomenons such as rotten or germination.Because manual peeling efficient is low, on average can only finish the 0.07 hectare operation for each person every day, and labour intensity is large, very arduous, every harvest season, the loss that causes owing in time peeling of fruit ear is quite large.Solve the corn ear husking problem and become the key issue that improves corn product quality, cut loss, liberation rural laborer.

The debarker core component is apparatus for peeling off, and the material of peeling rollers commonly used has two kinds of cast iron and rubber.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.Adopt the pairing of a cast iron spiral discaling roll and a rubber helical (petal rubber) peeling rollers 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 pairs 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 mainly is comprised of the rigidity peeling bitch at roll body, the helical raised that is arranged at the 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 debarker.

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 the leaf device, and fruit ear peeling effect 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 strengthens with the ability of breaking the binding of bract and fringe handle, walnut hulling rate is high, flexible because of rubber again, its seed damage rate is lower, but since the axially-movable resistance of corncob greater than cast iron roll, so its productivity ratio is lower.In view of the foregoing, the peeling parts should be selected the peeling rollers that cast iron roll and rubber rollers combination and grooved are arranged.Its structure is: the iron roll surface is welded with spiral reinforcement, at the other rubber stripping bar of installing of reinforcing bar; Rubber is installed in helicla flute is drawn the leaf device. to increase grasp force, reduce the damage to corncob; Spiral is divided into 3 parts, and anterior lead angle is little, takes second place in the middle part, and the rear portion is larger.

Its working (machining) efficiency of the corn husking roller of normally used full elastomeric material is low, because its roll surface is with spiral ridge, and has 3 joint spiral rubber rolls serial connections to form on every roller, and its serial connection process is manually.And the peeling rollers of elastomeric material is because the restriction of its material, and quick abrasion has in use had influence on the operating efficiency of debarker.

The utility model content

The technical problems to be solved in the utility model provides a kind of anti abrasive corn husking roller.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of corn husking roller, comprise the roll body that has many continuous spiral ridges on the outer surface, and axially all have a plurality of grooves along roll body on every spiral ridge.

Wherein, the number of described spiral ridge is 4 to 7.

Wherein, the number of described spiral ridge is 5.

Wherein, the number of a circumferential groove of described spiral ridge is 40.

The beneficial effect that adopts technique scheme to produce is: utilize peeling rollers of the present utility model, spiral ridge on the roll body outer surface can be convenient to fruit ear and glide along the line, add the teeth groove on the peeling rollers, increased the frictional force between peeling rollers and bract, peeling is easy in the course of the work to make peeling rollers, can improve the quiet rate of stripping of debarker; And what whole root timber material all adopted is the A3 steel part, has the advantage wear-resistant, that utilization rate is high.
