Abstract
The utility model relates to a rice/wheat thresher having secondary threshing; a cylinder is arranged between a fan and a weed opening at the side of a threshing device; a driven shaft is arranged at the center of the cylinder; a driven shaft is connected with a main shaft by a drive device; the cylinder is provided with a tooth plate; a cylinder cover is arranged at the upper part of the cylinder, and a semi-cylinder sieve is arranged at the lower part. The utility model has high cleanness rate of threshing; ejective grains are automatically collected, which avoids grain loss in process of threshing and improves grain yield; the utility model has reliable operation performance.
Description
The utility model belongs to agricultural machinery technological field, is a kind of improvement of rice-wheat thresher.
The rice-wheat thresher that generally adopts in the agricultural production at present mainly is made up of sheller unit, fan, drum sieve and oscillating riddle; sheller unit is with the threshing of rice wheat bundle; rice wheat particle is through drum sieve and oscillating riddle output; light weight sundries such as broken straw rod are moved to the left along shaft screen; blown out the weeds mouth by fan; because many rice wheat particles do not break away from broken straw rod in the threshing course, the result is blown with broken straw rod, causes waste.
The purpose of this utility model is the rice-wheat thresher that will provide a kind of threshing performance high.
Solution of the present utility model is to be equiped with a cylinder between sheller unit side fan and weeds mouth, there is driven shaft in centre of the drum, the driven shaft left end is connected with main shaft by driver, the other end is installed on the support, support and frame are fixed together, equally distributed tooth plate is housed on the cylinder, and there is jacket the top of cylinder, and the semicircle shaft screen is equipped with in the below.During work, main shaft drives driven shaft and cylinder rotation by driver, after the sheller unit threshing, the broken straw rod that has the grain of rice is blown in the jacket by fan, carry out the secondary threshing by the swing roller that has tooth plate, the grain of rice enters oscillating riddle output through the semicircle shaft screen, and broken straw rod is blown from the weeds mouth.
The utility model threshing performance height, the grain of ejection can reclaim automatically, avoids the grain loss in the threshing course, thereby improves grain yield, reliable working performance.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model partial sectional view;
Fig. 2 is the utility model sectional view.
The utility model is mainly by frame 1, sheller unit 2, main shaft 3, hood 4, fan 5, drum sieve 6, oscillating riddle 7 and weeds mouth 8 constitute, between sheller unit 2 side fans 5 and weeds mouth 8, be equiped with cylinder 9, there is driven shaft 10 at cylinder 9 centers, and driven shaft 10 left ends connect main shaft 3 by driver 11, and equally distributed tooth plate 12 is housed on the cylinder 9, there is jacket 13 cylinder 9 tops, and semicircle shaft screen 14 is equipped with in the below.Wherein driver can be belt pulley, gear train or bearing.
