Abstract
A cleaning chamber of a grain harvester with an air adjusting device comprises a fan, a fan shaft, a fan shell, an air guide strip, a cleaning sieve, a grain screw lower shell, a sundry screw and a sundry screw lower shell, wherein the air guide strip is in a strip-shaped bulge, is positioned inside the lower bottom surface of an air outlet of the fan and is parallel to the fan shaft, and is used for changing the wind direction, so that more wind is blown to the front part of the cleaning sieve, and the wind power at the rear part of the cleaning sieve is properly reduced.
Description
Technical Field
The utility model belongs to the technical field of agricultural machine, a seed grain harvester cleaning chamber that has air adjusting device.
Background
The existing cleaning chamber of the grain combine harvester adopts a design that a centrifugal fan blows air to a cleaning sieve, and the fan blows air is characterized in that the lower side of an air outlet of the fan is strong in wind power, the upper side of the air outlet of the fan is weak in wind power, the wind power is opposite to actual requirements, the front part of the cleaning sieve is small in wind power and causes accumulation, and the rear part of the cleaning sieve is too large and easily causes grain throwing.
Disclosure of Invention
The utility model aims at providing a seed grain harvester cleaning chamber that has air adjusting device makes the anterior wind-force of cleaning sieve big, and rear portion wind-force is little, alleviates the seed grain of cleaning sieve front end and piles up, reduces the seed grain of cleaning sieve rear end and shed.
The utility model provides a technical scheme that its technical problem adopted is: a cleaning chamber of a grain harvester with an air adjusting device comprises a fan, a fan shaft, a fan shell, an air guide strip, a cleaning sieve, a grain auger, a lower grain auger shell, a residue auger and a lower residue auger shell; the air guide strip is protruding in a strip shape, is positioned in the lower bottom surface of the air outlet of the fan, is parallel to the fan shaft, and is used for changing the wind direction, so that more wind blows to the front part of the sorting screen, and the wind power at the rear part of the sorting screen is properly reduced.
Compared with the prior art, the beneficial effects of the utility model are that: improve the seed grain cleanliness of seed grain harvester, reduce the loss rate.

Description of reference numerals: (1) the device comprises a fan, (2) a fan shell, (3) an air guide strip, (4) a cleaning sieve, (5) a kernel auger, (6) a kernel auger lower shell, (7) a tailing auger, (8) a tailing auger lower shell and (9) a fan shaft.
Detailed Description
As shown in the figure, the cleaning chamber of the grain harvester with the air adjusting device comprises a fan (1), a fan shaft (9), a fan shell (2), an air guide strip (3), a cleaning sieve (4), a grain auger (5), a grain auger lower shell (6), a residue auger (7) and a residue auger lower shell (8); the air guide strip (3) is protruding in a strip shape, is located inside the lower bottom surface of the air outlet of the fan and is parallel to the fan shaft (9), so that the strip-shaped protrusion is formed inside the lower bottom surface of the fan port which is originally a plane, the air guide strip is used for changing the wind direction, more wind blows to the front part of the sorting screen (4), and the wind power at the rear part of the sorting screen (4) is properly reduced.
The working state is as follows: the mixture with a large amount of seeds and bran leaves falls to the cleaning sieve (4), the front part is more and the rear part is less. The wind generated by the rotation of the fan (1) is blown out from the outlet of the fan shell (2), strong wind meets the wind guide strip (3) at the lower part of the wind outlet of the fan, part of the wind is folded to the front part of the sorting screen (4), meanwhile, because the upper part of the wind guide strip (3) is in a similar arc surface shape, part of the wind moves along the tangential direction of the arc surface, and the part of the wind blows to the middle rear part of the sorting screen (4), so that the wind on the sorting screen (4) has the effect of being from large to small from front to back. More bran and leaves are blown by strong wind to float at the front part of the cleaning sieve (4), are not easy to accumulate on the cleaning sieve (4), are beneficial to falling of grains through the cleaning sieve (4), fall into a lower shell (6) of the grain screw conveyor and are conveyed into a granary by the grain screw conveyor (5). The impurities such as bran, leaves and the like which are very light at the rear part of the cleaning sieve (4) are blown to the ground, the seeds which are not peeled completely fall into the lower shell (8) of the tailing auger, and the seeds are sent back to the cleaning sieve (4) by the tailing auger (7) for threshing and cleaning again.
Claims (1)
1. The utility model provides a seed grain harvester cleaning room that has air adjusting device which characterized in that: the device comprises a fan, a fan shaft, a fan shell, an air guide strip, a cleaning sieve, a seed auger, a lower shell of the seed auger, a residue auger and a lower shell of the residue auger; the air guide strip is protruding in a strip shape, is positioned in the lower bottom surface of the air outlet of the fan, is parallel to the fan shaft, and is used for changing the wind direction, so that more wind blows to the front part of the sorting screen, and the wind power at the rear part of the sorting screen is properly reduced.
