Description
Technical Field
The utility model relates to a cleaning machine, specific cleaning plant for crops of multistage wind channel, wind pressure that says so.
Background
Cleaning is a necessary step for separating seeds and impurities of harvested crops, and a cleaning device is a core component in crop harvesting automation. The working efficiency of the cleaning device directly influences the harvesting result of crops, and meanwhile, the quality and the cost of the subsequent processing of the crops are also directly influenced by the cleaning rate.
The existing cleaning device is mainly of a single-fan structure, particularly, a single color fan is matched with or not matched with an air channel to realize dynamic blowing separation of grain impurities, and due to the fact that the wind power uniformity of the single fan is poor, a cleaning low-pressure area, namely a cleaning low-efficiency area, often exists during cleaning, and in order to achieve the cleaning purpose, long cleaning time is often needed, the efficiency and the speed of the whole harvesting process are influenced, and therefore a large progress space still exists.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough that prior art exists, provide a cleaning plant for crops that reduces multistage wind channel, the wind pressure of cleaning low-pressure area.
In order to achieve the above object, the utility model adopts the following technical scheme: a cleaning device with multi-level air channels and air pressures for crops comprises a fixed frame body, a first cross flow fan, a second cross flow fan, a compensation fan and a control box, wherein the first cross flow fan, the second cross flow fan and the compensation fan are all arranged on the fixed frame body; the second cross flow fan is positioned at the lower right part of the first cross flow fan; the compensation fan is positioned at the upper left of the first crossflow fan; the impeller diameter of the first crossflow blower is larger than that of the second crossflow blower; the first cross flow fan is driven by a first motor to rotate; the second cross flow fan is driven by a second motor to rotate; the compensation fan is driven by the third motor to rotate; the air outlet of the first cross flow fan faces horizontally; an air outlet of the second cross flow fan forms an included angle of 75 degrees with the horizontal plane; the compensation fan is a centrifugal fan, and an air outlet of the compensation fan forms an included angle of 45 degrees with the horizontal plane; the control box is arranged on the fixed frame body, is respectively connected with the first motor, the second motor and the third motor and is used for respectively controlling the first motor, the second motor and the third motor to work; the air outlet pressure of the first cross flow fan is greater than that of the second cross flow fan; the air outlet pressure of the compensation fan is smaller than that of the second cross flow fan.
The utility model discloses during the implementation, utilize three different wind channels of group, different pressure relations, form and mutually support, realize the multi-angle, the air supply at no dead angle is cleaned.
The utility model discloses simple structure, reasonable in design utilizes above-mentioned structure can effectively solve the not enough that current single fan structure exists.
