Abstract
The invention discloses a threshing, cleaning and conveying device which comprises a threshing rack, a threshing cylinder, a front concave grate and a rear concave grate, wherein the threshing cylinder is disposed on the threshing rack; the bottom and the back of the threshing cylinder are wrapped by the front concave grate and the rear concave grate in parallel; a conveying belt is disposed under the front concave grate and the rear concave grate; a vibration screen is disposed under the conveying belt; the conveying belt is disposed in an inclined manner; and the tail end of the conveying belt points to the front part start end of the vibration screen. By this way, in the threshing, cleaning and conveying device disclosed by the invention, grains obtained by the threshing cylinder pass through the front concave grate and the rear concave grate and then fall onto the conveying belt, and the grains are then conveyed to the front part start end of the vibration screen by the conveying belt. The device ensures that all the grains are treated by grading, purification and filtration of the vibration screen; impurities in the grains are removed, a high threshing rate is achieved; the possibility in discharge of the grains along with the impurities is reduced; grain losses are reduced; and a grain output rate becomes high.
Description
Technical field
The present invention relates to threshing apparatus field, particularly relate to a kind of threshing and cleaning conveying plant.
Background technology
All feeding-in combine is because gathering in the various crop such as paddy rice, wheat, rape, and machinery utilization rate is high, simultaneously relatively simple, the advantage of lower cost of structure, accept by users.In the equipment of existing wheat and rice combine harvester threshing part, different structure, difform harvester threshing drum are all housed, the rotation of cylinder makes grain threshing.Longitudinal axial flow threshing device is that current all feeding-in combine configures comparatively novel sheller unit, and its major advantage is center of gravity connection and reasonable arrangement, and because threshing cylinder is longer, rotating speed is lower, and thus threshing percentage of damage is low few with cereal entrainment loss.
The shortcoming that longitudinal axial flow threshing device exists is exactly that grain cleaning loss is large compared with traditional transverse-axis-flow sheller unit, reason is because the threshing chamber length of threshing cylinder is longer, thus the sorting screen area of its sorting screen area ratio transverse axis flow threshing device is little, when cleaning inventory one timing, its cleaning loss is higher, particularly the grain at threshing chamber rear portion fails that vibratory sieve carries out classification, removal of impurities, filtration are just discharged, and cause the direct losses of grain, the percent of loss of cereal is higher.
Summary of the invention
