Abstract
The utility model discloses a seed cleaning device for a corn harvester, which comprises a vibration sieve, wherein the vibration sieve comprises a sieve panel, grid-shaped sieve holes and shell-shaped sieve holes are formed on the sieve panel and are respectively and fully spread over the front half part and the back half part of the sieve panel, an impurity cleaning fan is arranged on a machine frame of the corn harvester and is arranged under the front half part of the sieve panel, and in addition, an air outlet of the impurity cleaning fan is aligned with the back half part of the sieve panel. The seed cleaning device can greatly improve the cleanness of seeds, and meanwhile, the seed loss rate is effectively reduced.
Description
Technical field
The utility model relates to a kind of seed cleaning plant, relates in particular to a kind of maize harvesting machine seed cleaning plant.
Background technology
The general shell that adopts of the cleaning plant of domestic market maize harvesting machine sieves the formula vibratory sieve at present, and the cleannes effect of cleaning seed of this form vibratory sieve is relatively good, but the seed loss is bigger.Also have and adopt woven vibratory sieve, the loss of this structural vibrations sieve seed is fewer, but it is poor to clean the cleannes effect of seed.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of maize harvesting machine seed cleaning plant is provided, and this seed cleaning plant can significantly improve the cleannes of seed, effectively reduces the seed percent of loss simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: maize harvesting machine seed cleaning plant, the involving vibrations sieve, described vibratory sieve comprises the compass screen surface plate, described compass screen surface plate is provided with grid sieve aperture and shell-like sieve aperture, described shell-like sieve aperture and grid sieve aperture are covered with the first half and the latter half of described compass screen surface plate respectively, assorted clearly blower fan is installed on the described maize harvesting machine frame, and described clear assorted blower fan is arranged at the below of described compass screen surface plate first half and the latter half that air outlet is aimed at described compass screen surface plate.
As a kind of preferred scheme, evenly fixedly help the fortune tooth on the described compass screen surface plate.
As a kind of preferred scheme, the described fortune tooth that helps extends along the width of compass screen surface plate.
As a kind of preferred scheme, described vibratory sieve drives vibration by the eccentric wheel power set.
After having adopted technique scheme, effect of the present utility model is: because maize harvesting machine seed cleaning plant, the involving vibrations sieve, described vibratory sieve comprises the compass screen surface plate, described compass screen surface plate is provided with grid sieve aperture and shell-like sieve aperture, described shell-like sieve aperture and grid sieve aperture are covered with the first half and the latter half of described compass screen surface plate respectively, assorted clearly blower fan is installed on the described maize harvesting machine frame, described clear assorted blower fan is arranged at the below of described compass screen surface plate first half and the latter half that air outlet is aimed at described compass screen surface plate, therefore at first according to the flow direction of bract and seed, before the upstream that is in flow direction is defined as, after the downstream that is in flow direction is defined as.On the compass screen surface plate that bract after peeling off from the debarker of maize harvesting machine and seed have been fallen into vibratory sieve, shaker vibration, clear assorted blower fan is facing to the latter half blowing of compass screen surface plate, because shell-like sieve aperture screening cleannes effect itself is relatively good, bract is difficult for dropping from sieve aperture, therefore, the part seed just falls from the shell-like sieve aperture, the latter half that bract and the seed that do not separate of part and bract flow into the compass screen surface plate jointly, because grid sieve aperture screening cleannes itself are poor slightly, but seed falls from the grid sieve aperture easily, and bract itself is light, and floatability is good, the latter half that clear simultaneously assorted blower fan is aimed at the compass screen surface plate is dried downstream, thereby the bract flow further downstream on the grid sieve aperture is discharged outside the maize harvesting machine machine, so just can significantly improve the cleannes of seed, effectively reduce the seed percent of loss simultaneously.
Again owing to fixedly help the fortune tooth on the described compass screen surface plate, so vibratory sieve is in vibration processes, and bract and seed will clash into and help the fortune tooth, thereby bract is separated with seed more rapidly, thoroughly, and the while also helps the mobile of bract, is convenient to outside the bract discharge machine.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of the compass screen surface plate of the utility model embodiment;
In the accompanying drawing: 1. vibratory sieve; 11. compass screen surface plate; 12. grid sieve aperture; 13. shell-like sieve aperture; 14. help the fortune tooth; 2. linkage; 3. assorted clearly blower fan; 4. seed gathering unit; 5. eccentric wheel power set.
Embodiment
The front and back of being mentioned in the utility model are according to the flow direction definition of bract and seed vibration, before the upstream that is in flow direction is defined as, after the downstream that is in flow direction is defined as.
A kind of maize harvesting machine seed cleaning plant, as depicted in figs. 1 and 2, its involving vibrations sieve 1, described vibratory sieve 1 is installed on the frame of maize harvesting machine by linkage 2, described bar linkage structure and the parallel four-bar linkage structure of vibratory sieve 1 common composition, described vibratory sieve 1 is vibrated by 5 drivings of eccentric wheel power set, vibration power is provided for vibratory sieve 1 by the eccentric wheel of eccentric wheel power set 5.Described vibratory sieve 1 comprises compass screen surface plate 11, described compass screen surface plate 11 is provided with grid sieve aperture 12 and shell-like sieve aperture 13, described shell-like sieve aperture 13 and grid sieve aperture 12 are covered with the first half and the latter half of described compass screen surface plate 11 respectively, and the below of described compass screen surface plate 11 is equipped with seed gathering unit 4.Assorted clearly blower fan 3 is installed on the described maize harvesting machine frame, and described clear assorted blower fan 3 is arranged at the below of described compass screen surface plate 11 first halfs and the latter half that air outlet is aimed at described compass screen surface plate 11.
Evenly fixedly help fortune tooth 14 on the described compass screen surface plate 11, help fortune tooth 14 to be welded with compass screen surface plate 11.The described fortune tooth 14 that helps extends along the width of compass screen surface plate.
Operation principle of the present utility model is: bract and seed after peeling off from the debarker of maize harvesting machine have been fallen on the compass screen surface plate 11 of vibratory sieve 1, vibratory sieve 1 vibration, clear assorted blower fan 3 is facing to the latter half blowing of compass screen surface plate 1, because it is relatively good that shell-like sieve aperture 13 itself sieves the cleannes effect, bract is difficult for dropping from sieve aperture, therefore, the part seed just falls from shell-like sieve aperture 13, the latter half that bract and the seed that do not separate of part and bract flow into compass screen surface plate 11 jointly, because it is poor slightly that grid sieve aperture 12 itself sieves cleannes, but seed falls from grid sieve aperture 12 easily, and bract itself is light, floatability is good, the latter half that clear simultaneously assorted blower fan 3 is aimed at compass screen surface plate 11 is dried downstream, thereby the bract flow further downstream on the grid sieve aperture 12 is discharged outside the maize harvesting machine machine, so just can significantly improve the cleannes of seed, effectively reduce the seed percent of loss simultaneously.
