Description
Technical field
The utility model belongs to maize harvesting machine technical field, more particularly to a kind of ear-snapping unit.
Background technology
Current maize harvesting machine is broadly divided into fruit ear harvest and two kinds of grain harvest, compared with fruit ear cropper, Corn Seeds
Grain cropper can greatly save peasant labor force, reduce labor intensity, production efficiency be improved, while can also be harvester user
Higher income is provided.Ceding of Taiwan ear-picking unit is critical component during corn kernel harvest, and corn kernel harvest is played
Vital effect, if structure design is unreasonable often to occur that stem pulling effect is undesirable, stem pulling device is damaged, life-span drop
It is low.
Cantilevered stem pulling device, rice-pulling chain tensioning wheel are used away from drawing currently used for the ear-picking unit of the cropper of corn kernel
Stem knife is smaller apart from the substantially parallel intersection of the too small and chain of rice-pulling chain two.
For cantilevered stem pulling device, because stem pulling roller is coordinated with transmission case using splined shaft, requirement on machining accuracy is very
Height, the cooperation requirement of splined shaft and manufacturing cost are also corresponding very high, because stem pulling device front end is outstanding during corn kernel harvest
Sky, stem pulling roller is impacted in operation process by stalk presetting roller blade, long working can cause whole harvesting frame deformation and
Cutting knife is damaged, and damages more serious when particularly corn kernel moisture content is higher.In addition, the stem pulling resistance to overturning of the structure compared with
Difference, maintenance cost is higher.
Rice-pulling chain tensioning wheel away from stem pulling knife apart from too small, because helping standing grain time mistake apart from small rice-pulling chain in harvesting process
It is short, help standing grain effect is poor easily to push over corn stem or block harvesting passage, for the big corn field of line-spacing deviation, this problem is outstanding
For protrusion.
The chain of rice-pulling chain two is substantially parallel, and intersection is smaller, and group standing grain effect is poor, is gathered in for high speed, when material is more, dials
The effect of standing grain chain does not have, and causes feeding end stacking material influence harvesting；Rear end rice-pulling chain has crossover phenomenon, and corn stem is in quilt
By the multiple strike of rice-pulling chain during leaving behind, easily easily snap off, pushed by rice-pulling chain in feeding screw feeder and enter body.
Excessive stalk can increase threshing and cleaning load into roller and cause harvesting performance indications exceeded.
Utility model content
Technical problem to be solved in the utility model is：A kind of ear-snapping unit is provided, ceding of Taiwan front end can be reduced
The frequency is blocked, stem pulling effect is improved, it is ensured that the fluency of corn stem feeding, the line-spacing accommodation of the ceding of Taiwan is widened, raising is cut
The harvest performance of platform and complete machine.
In order to solve the above technical problems, the technical solution of the utility model is：Ear-snapping unit, including two relative set
The rice-pulling chain put, the rice-pulling chain is circumferentially positioned on active rice-pulling chain wheel and driven rice-pulling chain wheel, the lower section of the rice-pulling chain
Stem pulling roller is correspondingly arranged on respectively, and the rear end of the stem pulling roller is connected with transmission case, and the diameter of the driven rice-pulling chain wheel is more than
The diameter of the active rice-pulling chain wheel；The moving tooth track front end of two rice-pulling chains intersects, and rear end is provided with gap.
As an improvement, between the centre of gyration of the driven rice-pulling chain wheel and the stem pulling knife front end of the stem pulling roller
Distance is more than 200mm.
As an improvement, the maximum cross distance of the moving tooth track front end of two rice-pulling chains is more than 10mm.
As an improvement, at the stem pulling knife back-end location of the moving tooth track correspondence stem pulling roller of two rice-pulling chains
Spacing be more than 10mm.
As an improvement, the stem pulling roller front end is rotatably installed in harvesting frame, and rear end is connected by Hooks coupling universal coupling
Connect the transmission case.
As a further improvement, it is arranged with the starting taper of the stem pulling roller in bearing block and bearing, the harvesting frame
Connecting plate is installed with, the connecting plate and the bearing block are fixed together by fastener.
As a further improvement, the Hooks coupling universal coupling is ball pivot.
As a further improvement, the upper front in the stem pulling roller of the harvesting frame is provided with guide fence plate.
As an improvement, the output of the transmission case is provided with potted component.
As a further improvement, the potted component is lip-type packing, and the lip-type packing is located at the transmission
On the casing of case.
Employ after above-mentioned technical proposal, the beneficial effects of the utility model are：
Because the diameter of the driven rice-pulling chain wheel of ear-snapping unit is more than the diameter of the active rice-pulling chain wheel；Two institutes
The moving tooth track front end for stating rice-pulling chain intersects, and rear end is provided with gap so that rice-pulling chain front end increases stalk chucking power, has preferably
Help and act on, reduce stalk and push over, solve stem pulling end folder fringe phenomenon；Stalk is when close to stem pulling knife afterbody, from rice-pulling chain
Strike, makes stalk smoothly be left behind by stem pulling roller, reduces the amount for entering threshing cylinder stalk, obtains satisfied harvest effect.
The ear-snapping unit that the utility model is provided, reduces ceding of Taiwan front end and blocks the frequency, the stem pulling effect of stalk is obtained
To significantly improving, it is ensured that the fluency of corn stem feeding, the line-spacing accommodation of the ceding of Taiwan is widened, the ceding of Taiwan has been improved and whole
The harvest performance of machine.
The distance between the centre of gyration and stem pulling knife front end of the stem pulling roller due to the driven rice-pulling chain wheel are more than
200mm so that group standing grain time of rice-pulling chain is long, lodging harvest effect is better than small pitch structure, is received for the corn of line-spacing deviation
Obtain effect particularly evident.
Because the maximum cross distance of the moving tooth track front end of two rice-pulling chains is more than 10mm, stem is further reduced
Stalk is pushed over.
Because the spacing at the stem pulling knife back-end location of the moving tooth track correspondence stem pulling roller of two rice-pulling chains is big
In 10mm, the amount into threshing cylinder stalk is further reduced.
Because the stem pulling roller front end is rotatably installed in harvesting frame so that stem pulling roller front support is in harvesting frame
On, improve impact resistance of the stem pulling roller to stalk in operation process；By stem pulling roller rear end by Hooks coupling universal coupling connects institute
Transmission case is stated, not only easy to assembly compared with traditional splined shaft is connected, cost reduction substantially increases reliability.
Because the upper front in the stem pulling roller of the harvesting frame is provided with guide fence plate, pass through guide fence plate
Guide effect, is easy to stalk to enter.
Because the output of the transmission case is provided with potted component, sealing is carried out to transmission case using potted component anti-
Shield, good sealing effect prevents dust, weeds etc. from entering transmission case.
