Abstract
The utility model discloses a harvester grading sieve which comprises a plurality of louver sieve plates that are arranged on a sieve frame in sequence, a plurality of louver sieve pieces that are arranged at the front parts of the sieve plates in sequence and a plurality of bar penetrating holes that are respectively arranged at the rear parts of the sieve plates in sequence, wherein, all sieve plates are connected in series through bars that pass through the corresponding bar penetrating holes on the sieve plates in sequence. The harvester grading sieve can avoid the phenomena of short straw, smashed leaves with larger sizes and the leakage of sundries, such as cavings and so on that are caused by larger clearances formed by the opening-degree adjustment among the louver sieve plates, thereby greatly improving the grading effect and the harvesting operation adaptability of the harvester.
Description
Technical field
The utility model relates to a kind of screening plant, especially relates to the reaping machine grading sieve that a kind of cleaning and sorting system of harvester is used.
Background technology
At present, the screening plant of cleaning and sorting system of harvester has multiple, the adjustable chip fish scale sorting screen that wherein adopts multi-disc fish scale sieve plate to be arranged in order formation is a kind of screening plant commonly used, when screening operation, controls the aperture of each fish scale sieve plate by the lip(ped) sieve adjusting device.But when the fish scale sieve plate opens, between sieve plate, can form big slit at adjacent sieve plate, being cleaned foreign material such as material such as short straw, the broken leaf of large-size, clever chaff will leak down from these slits, influenced and cleaned effect, reduced and cleaned quality, made the harvest operation adaptability of grain header be subjected to certain limitation.
Summary of the invention
Technical problem to be solved in the utility model provided a kind of can avoid between lip(ped) sieve sieve plate and the sieve plate carry out aperture when adjusting because of forming the phenomenon that bigger slit causes foreign material such as the broken leaf of short straw, large-size, clever chaff to leak down, improved greatly and cleaned effect and the adaptive reaping machine grading sieve of grain header harvest operation.
For solving the problems of the technologies described above, the technical solution of the utility model is: reaping machine grading sieve, comprise being arranged in order on the screen frame and be provided with some lip(ped) sieve sieve plates, the sieve plate front portion is arranged in order and is provided with some lip(ped) sieve sheets, described each sieve plate rear portion is arranged in order respectively and is provided with some cylindrical voids of wearing, and some bars of wearing pass the corresponding cylindrical void and with each sieve plate string together worn on each sieve plate respectively successively.
As a kind of improvement, the described front end that respectively sieves sheet is respectively equipped with digitation, and is provided with finger between the adjacent two sieve sheets.
As further improvement, on described finger and the sieve sheet stagger apart from a in the plane.
The reaping machine grading sieve of technique scheme, owing to be to have adopted to be arranged in order on the screen frame to be provided with some lip(ped) sieve sieve plates, the sieve plate front portion is arranged in order and is provided with some lip(ped) sieve sheets, each sieve plate rear portion is arranged in order respectively and is provided with some cylindrical voids of wearing, and some bars of wearing pass the corresponding cylindrical void and with each sieve plate string together worn on each sieve plate respectively successively.Such structure, the corresponding bar of wearing of wearing cylindrical void opens between back sieve plate and the sieve plate bigger slit with adjustment and cuts apart on each sieve plate by passing, form some little spaces, can avoid between lip(ped) sieve sieve plate and the sieve plate carry out aperture when adjusting because of forming the phenomenon that bigger slit causes foreign material such as the broken leaf of short straw, large-size, clever chaff to leak down, improved greatly and cleaned effect and grain header harvest operation adaptability.And adopt front end to be respectively equipped with digitation at each sieve sheet, be provided with finger between the adjacent two sieve sheets, and adopt on finger and the sieve sheet plane distance that staggers, can further strengthen the cleaning of foreign material such as the broken leaf of short straw, large-size, clever chaff by digitation or finger, clean quality and clean effect with raising.

Embodiment
As Fig. 4 and shown in Figure 3, reaping machine grading sieve, be included in to be arranged in order on the screen frame 5 and be provided with some lip(ped) sieve sieve plates 1, be arranged in order in the front portion of sieve plate 1 and be provided with some lip(ped) sieve sheets 2, the aperture of controlling each fish scale sieve plate 1 by the lip(ped) sieve adjusting device is to adapt to the different operating environments of cleaning; Be arranged in order respectively at each sieve plate 1 rear portion and be provided with some cylindrical voids 4 of wearing, some bars 6 of wearing pass the corresponding cylindrical void 4 and with each sieve plate 1 string together worn on each sieve plate 1 respectively successively, in actual use, wearing bar 6 can adopt steel wire to wear bar to improve service life, each steel wire is worn bar and is passed successively respectively and wear cylindrical void on each sieve plate accordingly, wear being arranged in order of bar by the steel wire that is through in the cylindrical void, slit bigger between back sieve plate and the sieve plate is opened in adjustment to be cut apart, form some little spaces, can avoid when carrying out the aperture adjustment, causing short straw between lip(ped) sieve sieve plate and the sieve plate because of forming bigger slit, the broken leaf of large-size, the phenomenon that foreign material such as grain husk chaff leak down.
As depicted in figs. 1 and 2, front end at each sieve sheet 2 is respectively equipped with digitation 21, and be provided with finger 3 between the adjacent two sieve sheets 2, can adopt simultaneously finger 3 and sieve the sheet 2 planes mode apart from a that as above staggers between the plane,, clean quality and clean effect the cleaning of foreign material such as the broken leaf of short straw, large-size, clever chaff with further enhancing with raising.And finger 3 and digitation 21 all can adopt the steel bar that is solidified as a whole with lip(ped) sieve sieve plate 1.And wear cylindrical void 4 and can be located at sieve plate 1 rear portion and finger 3 relevant positions.
