Basic frame be used for fixed concave type sieve to keep the working shape of concave type sieve, avoid warping, the buffer memory has the effect of good temporary storage bean pod, can carry out the buffer memory with a large amount of bean pods that get into in short-term, reduces the problem of jam.

Furthermore, the turnover drum is of a transversely-arranged drum structure which works in a rotating mode, scrapers are formed on the outer circle of the turnover drum, the scrapers are evenly arranged on the circumferential surface at intervals, breaking gaps opposite to the toothed nails are reserved among the scrapers, and the bean pods are pressed in the breaking gaps to be broken. The scraper structure on the turnover drum has a good stirring effect, the movement efficiency of the bean pods is effectively improved, the bean pods can be more frequently impacted with the toothed nails, and the breaking efficiency is improved.

Furthermore, the teeth pins are welded on the concave sieve plate, are arranged at intervals on the axial length of the concave sieve plate and are linearly arranged on a circumferential path, so that a breaking blocking structure working circumferentially is formed, and circular filtering holes are formed on the concave sieve plate around the teeth pins. The pick passes through the welding to be fixed, and is reliably durable to conveniently repair, the seed grain can be passed through to the filtration round hole around the pick to high efficiency, improves the efficiency of sieving.

Furthermore, the concave sieve plate is integrally formed by bending a plate, and sieving round holes in an arc-shaped working area are uniformly and tightly arranged and are formed in a centralized manner by punching. The concave sieve plate is integrally formed by an integral plate, the durability is good, the sieving closure is good, the grain collection quality is good, and the breakage rate is low.

Compared with the prior art, the utility model, have following advantage and effect: the round hole concave sieve of this design improves for collecting the soybean, sets up the tooth nail structure on the concave sieve, has increased the speed of breaking open of pod, and the quickly separating seed grain to can effectively concentrate the collection, reduce the damage of soybean, can carry out the institutional advancement that corresponds on the concave sieve that has now, the adaptability of structure is good, can effectively improve the working life of concave sieve, better adaptation banding planting crop reaps.
