Background
Grain cleaning is an indispensable loop in grain mechanized harvesting, and the efficiency and the speed of the whole mechanical harvesting are directly influenced by the grain cleaning efficiency and the cleaning speed. The existing grain cleaning assembly mostly uses an axial fan, positive wind pressure is provided by the axial fan, and bran impurities in grains are blown off from bottom to top. In the middle of the actual use, the bran that blows up is miscellaneous sometimes influenced by the environmental air current, can not blow out and send a grain way, and it gets back to the corn again after being blown up promptly, influences the miscellaneous efficiency of removing of cleaning, in addition, because single fan is behind the positive pressure air current that generates, lacks the air current guide, causes its utilization ratio lower, can not fine satisfy the needs that actual results were used.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough that prior art exists, provide one kind and use two different specification fans to realize that a guide type cleans the air current, and then improve the grain cleaning subassembly of cleaning efficiency and cleaning the multi-fan of speed.
In order to achieve the above object, the utility model adopts the following technical scheme: a grain cleaning component with double fans comprises a shell, a main fan, a lower auxiliary fan and a cleaning material plate, wherein the cleaning material plate is horizontally arranged in the shell; an inverted V-shaped discharging air guide channel positioned at the upper right of the sorting plate is arranged in the shell, and the corner of the discharging air guide channel is in arc transition; the main fan is arranged in the shell and is positioned below the cleaning material plate; the main fan comprises a volute and an impeller, and the volute is provided with a main air outlet channel and a Y-shaped auxiliary air outlet channel; the main air outlet channel extends out from the horizontal direction to the right; the shell is internally provided with an air deflector which is oppositely matched with the main air outlet channel and is used for guiding the airflow of the main air outlet channel to the oblique upper direction, and the airflow passes through the cleaning material plate and then flows out through the discharging air guide channel to clean the cleaning material plate; the Y-shaped auxiliary air outlet channel is arranged on the upper left side of the volute and divides partial airflow generated by the impeller into two branches to be sent out, wherein one branch is positioned below the cleaning material plate and horizontally flows out to supplement the airflow of the main air outlet channel, and the other branch forms a 45-degree included angle with the cleaning material plate, penetrates through the upper part of the cleaning material plate, is guided by the shell and enters the discharging air guide channel; the lower auxiliary fan is arranged in the shell and is positioned on the right side of the main fan; the air outlet channel of the lower auxiliary fan is at 45 degrees and is opposite to the air outlet of the discharging air guide channel; the airflow generated by the lower auxiliary fan is guided by the guide plate which is correspondingly matched in the shell to turn backwards, and the airflow is the same as the air outlet direction of the material discharging guide channel and is used for guiding the airflow generated by the material discharging guide channel.
The utility model discloses simple structure, reasonable in design utilizes the structural design of above-mentioned two wind platforms, realizes more effectual air current guide, has also guaranteed cleaning scope and cleaning effect.
