The peeling-off mechanism of the corn harvesting machine comprises a plurality of groups of driving rollers and driven rollers, and the driving rollers and driven rollers are oppositely paired for peeling, and the peeling-off mechanism is characterized in that each group of the driving roller and driven roller are vertically staggered; W-shaped groove-shaped configuration is formed by each group of the driving roller and driven roller; a spiral steel bar section is arranged on the surface of the front half section of each group of the driving rollers, and a rubber roller section with a spiral groove is arranged on the surface of the rear half section of each group of the driving roller; and a square rubber bulge is arranged on the surface of each group of the driven roller.
Description
Technical field
The present invention relates to agricultural maize harvesting machine, particularly relate to a kind of peeling procedure of maize harvesting machine.
Background technology
Maize harvesting machine once completes to corn the farm machinery that harvesting, heap, cane once go back the multi-mode operations such as field when corn is ripe.The primary structure of the peeling procedure of maize harvesting machine comprises walking chassis, be arranged on actuating unit on walking chassis and driver's cabin, the ceding of Taiwan being arranged on walking front, chassis and apparatus for cutting of straws, the debarker being arranged on walking rear, chassis and fruit-ear box.The peeling procedure of current maize harvesting machine, often have the following disadvantages: 1. drive roll and driven voller all adopt single steel rider or rubber rollers, single steel rider grasp force is little, easily weares and teares in surface, be unfavorable for peeling, and single rubber rollers lengthwise movement resistance is large; 2. in prior art, the arrangement of drive roll and driven voller adopts horizontal usually, easily skids between corncob and two rollers.
Summary of the invention
The invention is intended to the peeling procedure that a kind of maize harvesting machine is provided, little to solve the grasp force adopting single steel rider to exist in prior art, the lengthwise movement resistance adopting single rubber rollers to exist is large, and the problem that the corncob of the arrangement mode existence of drive roll and driven voller easily skids.
The peeling procedure of maize harvesting machine of the present invention, comprise many group drive rolls and driven voller, drive roll and driven voller pair roller, it is characterized in that, often group drive roll and driven voller shift to install all up and down, and each group drive roll and driven voller form the configuration of W grooved, and the drive roll first half section surface often organized is spiral reinforcement section, second half section surface is the rubber rollers section with helical groove, and the driven voller surface often organized is provided with square rubber projection.
Beneficial effect of the present invention: 1. drive roll is by adopting rubber and cast steel fabricated structure, because corncob has just entered between two rollers, it is the first half section that is positioned at two rollers, and now corncob is also incomplete is separated with pocket, pocket directly with roll surface contact frictional resistance greatly, therefore the first half section of drive roll is designed to spiral steel rider section, reduce frictional resistance, the second half section of drive roll is designed to rubber rollers section, increases grasp force, mainly completes the peeling operation of corncob.2. drive roll first half section spiral steel rider section, second half section rubber rollers section, driven voller is arranged square rubber bumps, the design of this kind of roll surface, corncob can be made not only to move in the axial direction, but also rotate around own axes direction, more be conducive to peeling; 3. many groups adopt the configuration of W grooved, can guarantee in operation process, corncob ordered arrangement, reduce the skidding of corncob, improve and dial clean rate.
Further, drive roll, by sprocket wheel chain drive, also passes through sprocket wheel chain drive between drive roll and driven voller.By sprocket wheel chain drive, stable transmission, compact conformation.
Further, in order to avoid long-term operation, some seeds dropped stick on roll surface, are also provided with cleaning mechanism, and cleaning mechanism comprises and drives the cleaning brush that can swing along the axial reciprocating of roller by power.
Further, the radius of spiral reinforcement section is less than the radius of rubber rollers section, and two drive rolls of adjacent sets are relative, have gap between the spiral reinforcement section of two adjacent groups drive roll.By the gap between two spiral steel rider sections, the seed peeled off in peeling process can be passed through by gap smoothly, reclaims.
