Description
Technical field
The present invention relates to a kind of agricultural harvesting machinery, specifically a kind of maize harvesting machine fruit ear bract shredding mechanism.
Background technology
Maize harvesting machine once completes to corn the farm machinery that harvesting, heap, stem stalk once go back the multi-mode operations such as field with machinery when corn is ripe.Current maize harvesting machine does not generally configure fruit ear bract shredding mechanism, and one is because the restriction of maize harvesting machine space structure; Two is because fruit ear bract is lighter and soft, not easily shreds.If maize harvesting machine does not configure fruit ear bract shredding mechanism, then make to be with the maize harvesting machine of peeling function after operation, whole fruit ear bract will be left on field.Such fruit ear bract not only can not also add the inconvenience in arable land as fertilizer.In order to solve the problem, Chinese invention patent specification CN202713962U discloses a kind of bract shredding mechanism of maize harvesting machine.This bract shredding mechanism is installed on the chassis main frame of described maize harvesting machine, and the bract being positioned at described maize harvesting machine exports the below of screw feeder; Described bract shredding mechanism comprises housing, is provided with the arbor association for chaffy corn bract in described housing, and described arbor association connects the transmission device for driving arbor association to rotate, described transmission device connecting drive device.Described arbor association comprises cutter shaft, and the periphery of described cutter shaft is provided with some tool rests distributed for center of circle annular array with the cutter shaft centre of gyration, and described tool rest is provided with blade.Described tool rest is provided with three groups along the axis direction of cutter shaft.Described transmission device comprises the first power transmission shaft be connected with described drive unit, described first power transmission shaft connection for transmission case, and described transmission case connects second driving shaft, and described second driving shaft connects described cutter shaft.Described second driving shaft is Cardan shaft.
, there is following shortcoming in a kind of bract shredding mechanism of maize harvesting machine disclosed in Chinese invention patent specification CN202713962U:
1, this device " described arbor association comprises cutter shaft, and the periphery of described cutter shaft is provided with some tool rests distributed for center of circle annular array with the cutter shaft centre of gyration, and described tool rest is provided with blade." arbor association is just used alone the chopping of flail knife formula; utilize flail knife and air flow principle to realize cutting, flail knife and air flow principle are relatively applicable to the pulverizing of hard stalk, and poor for soft and light bract effect; chopping result is bad, makes fruit ear bract still be difficult to change into fertilizer;
" described transmission device comprises the first power transmission shaft be connected with described drive unit, described first power transmission shaft connection for transmission case, and described transmission case connects second driving shaft, and described second driving shaft connects described cutter shaft " of 2, this device.The action of transmission device so needs to carry out transferring power by the first power transmission shaft, interaction between second driving shaft and transmission case, and its transmission structures is complicated;
3, this device is in the process of chopping, and the seed that bract is carried secretly can not be cleaned, thus is shredded with bract one piece, and the percentage of damage of seed is high;
4, this device is arranged on the below that bract exports screw feeder, the space up and down of maize harvesting machine is increased, is unfavorable for maintaining.
summary of the invention
Technical assignment of the present invention is for above weak point, a kind of fruit ear bract is provided to shred thoroughly, transmission structures is simple, the seed that bract is carried secretly can be cleaned, make seed can not be shredded, reduce the percentage of damage of seed, effectively can utilize a kind of maize harvesting machine fruit ear bract shredding mechanism of locus.
The technical solution adopted for the present invention to solve the technical problems is: comprise housing and be arranged on the knife combination of enclosure interior, housing offers bract entrance, the outlet of broken bract; Also comprise drive unit, drive shaft, drive shaft to be crossed in housing and is arranged in housing both ends of the surface by bearing block, and the drive unit being arranged on hull outside drives drive shaft to rotate; Knife combination comprises stationary knife combination and combines with moving knife, stationary knife combination comprises stationary knife tool rest and ledger-plate, stationary knife tool rest is fixed on housing, stationary knife tool rest is fixed with ledger-plate, moving knife combination comprises moving knife tool rest and knife section, moving knife tool rest is fixed on drive shaft, and moving knife tool rest is fixed with knife section, and drive shaft rotates thus knife section rotation is worked in coordination with ledger-plate and cuts.
In described stationary knife combination, stationary knife tool rest is fixed with 1 ledger-plate, moving knife tool rest is fixed with 2 parallel knife sections, drive shaft rotates and knife section is rotated, thus 2 knife sections to be worked in coordination cutting by the both sides of 1 ledger-plate.
Described knife combination is provided with 1 ~ 8 group, preferred knife combination is provided with 3 groups, and cutting effect is best, structure space is the most reasonable, often organize knife combination to have included the combination of 2 groups of stationary knifes and combine with 2 groups of moving knife, often organize 2 groups of stationary knifes combinations of knife combination and 2 groups of moving knife and combine and be arranged on the same radial section of enclosure interior; The stationary knife tool rest of 2 groups of stationary knife combinations is all arranged on housing, each stationary knife tool rest is fixed with 1 ledger-plate; The moving knife tool rest of 2 groups of moving knife combinations is all arranged on drive shaft, each moving knife tool rest is fixed with 2 parallel knife sections; Drive shaft rotates and the 2 groups of moving knife combinations often organizing knife combination is rotated, wherein often organize 2 knife sections of moving knife combination successively through both sides, the cutting of working in coordination of the ledger-plate of 2 groups of stationary knife combinations, namely drive shaft rotates 1 circle and often organizes the cutting 4 times of working in coordination that knife combination completes knife section and ledger-plate.
Described columniform housing is combined into by semi-cylindrical shell of top cover and semi-cylindrical bottom plate shell tightening buckle; Shell of top cover has bract entrance, bottom plate shell has the outlet of broken bract; Drive shaft between bottom plate shell and shell of top cover, cross in housing, the two ends of drive shaft are arranged in bottom plate shell and shell of top cover both ends of the surface respectively by bearing block; The stationary knife tool rest of stationary knife combination is fixed on bottom plate shell.
Described also including is cleaned and conveying plant, clean and conveying plant comprise clean conveying screw feeder, water conservancy diversion conveying screw feeder, broken leaf sheds plate, seed portals;
Clean conveying screw feeder, water conservancy diversion conveying screw feeder and broken leaf to shed plate and be in axial direction successively set on drive shaft, water conservancy diversion conveying screw feeder is corresponding in the radial position of drive shaft to moving knife tool rest, moving knife tool rest is positioned on the side of drive shaft, and water conservancy diversion conveying screw feeder is positioned on the side of the drive shaft vertical with moving knife tool rest;
