Abstract
The utility model discloses a grain separating device of scraper harvest machinery, which comprises a chain wheel, a chain, a scraper, a separating mesh screen, a casing and the like. A grain inlet is formed at one end of the casing; the separating mesh screen and an air separation chamber comprising a grain outlet, an impurity discharge hole, an air inlet and an exhaust opening are installed at the other end of the casing; the air inlet of the air separation chamber is connected with an air outlet of a fan through a pipeline to form blowing; the exhaust opening of the air separation chamber is connected with an air inlet of another fan through a pipeline to form an air draft, so that a separating air duct is formed in the casing; grains separated through the separating mesh screen drop into the air separation chamber to be conducted to air separation; dust and small and broken weeds are sucked away through the fans and discharged out off the grain separating device; clean grains are taken into bags to be packaged; impurities in the separating mesh screen are discharged through the impurity discharge hole; and the discharged impurities return to a threshing machine or are collected to be separated again. The grain separating device integrates chain scraper lifting, mesh screen separating, impurity recovering and separating again, screening and air separating, has a simple structure and small size, does not adopt alternating motion, is small in vibration, and large in separation amount, ensures that grains are clean, and has stable and reliable performances.
Description
Affiliated technical field
The utility model relates to agricultural harvesting machinery seed cleaning device.
Background technology
Current agricultural machinery is developed rapidly, traditional harvest machinery seed cleaning device is comprised of vibratory sieve, blower fan etc., the harvest machinery seed cleaning system of existing China production and application has installed assorted remaining lifting, re-threshing roller etc. additional, but become, complex structure large at volume, manufacturing cost is higher, consumption of power is large, particularly in small-sized harvest machinery, be difficult to realize.
Summary of the invention
The utility model is that chain scraper promotes, screen cloth is cleaned, the seed cleaning device that selection by winnowing is integrated is cleaned, screened in assorted remaining recovery again.
Technical solutions of the utility model are: by sprocket wheel, the chain lifting scraper plate, separating screen, promote housing, the compositions such as selection by winnowing chamber housing, the lifting scraper plate is housed on the chain, housing one end has the seed entrance, the other end is equipped with separating screen and has impurity discharging port, the seed outlet, air inlet, the inlet scoop, air inlet is connected with the air outlet of blower fan with pipeline and produces blowing, the inlet scoop is with the pipeline generation air draught that is connected with the air inlet of another blower fan, when being configured on the small-sized harvest machinery, the seed cleaning amount hour, air inlet can not be connected or air inlet with blower fan, the seed outlet is merged into an opening, and housing is connected with blower fan to consist of and cleans the air channel; Seed runs to segregation section and separates in sieve screen apertures, the selection by winnowing again through the selection by winnowing chamber, the air draught that dust, little broken weeds are produced by blower fan from the inlet scoop siphon away and the discharge machine outside, the seed of cleaning falls into collection dress in the bag; Assorted remaining by the impurity discharging port discharge, the weeds of discharge and a small amount of seed can return in the thresher or after collecting to be cleaned again.
The beneficial effects of the utility model are: solved that harvest machinery seed cleaning device volume is large, complex structure, manufacturing cost is higher, consumption of power is a large difficult problem, a difficult problem that particularly is difficult to realize in small-sized harvest machinery has improved dependability; The utility model is simple in structure, volume is little, vibration is little without moving back and forth, seed cleans, the amount of cleaning is large, stable and reliable for performance.
