Problems solved by technology

However, when the fish scale sieve plate is opened, a large gap will be formed between the adjacent sieve plates, and the cleaned materials such as short straw, large-sized broken leaves, chaff and other debris will come out of these sieve plates. The leakage in the gap affects the cleaning effect and reduces the cleaning quality, which limits the adaptability of the harvester to a certain extent.

Example Embodiment

[0013] like Figure 4 and image 3 As shown, the harvester cleaning screen includes a number of fish scale screen sieve plates 1 arranged in sequence on the screen frame 5, and a number of fish scale screen plates 2 arranged in sequence at the front of the sieve plate 1, which are controlled by the fish scale screen adjustment device. The opening of each fish scale sieve plate 1 is suitable for different cleaning operation environments; a number of perforation holes 4 are arranged in sequence at the rear of each sieve plate 1, and a number of perforation strips 6 pass through the corresponding perforations on each sieve plate 1 in sequence. The strip holes 4 and the sieve plates 1 are strung together. In actual use, steel wire strips can be used for the thread strips 6 to improve the service life. By arranging the wire piercings in the piercing holes in sequence, the larger gap between the sieve plate and the sieve plate after adjustment and opening is divided to form several sm

Abstract

The invention discloses a grading sieve of a harvester, which comprises a plurality of louver sieve plates sequentially arranged on a sieve frame, a plurality of louver sieve sheets are sequentially arranged in the front of the sieve plate, a plurality of penetrate bar holes are respectively arranged in the back of the sieve plate, and all the sieve plates are strung together after respectively passing through the corresponding penetrate bars of the penetrate bar holes of the sieve plates. The grading sieve can avoid the phenomenon that sundries such as short straws, larger sized tatter leaves and chaffs leak from larger cracks among the louver sieve plates formed in opening adjustment, thereby greatly improving sieving effect and the suitability of harvesting operation of the harvest machine.
