GRAIN AND FERTILIZER COLLECTOR

摘要

GRAIN AND FERTILIZER COLLECTOR Disclosed is a particulate vacuum collector device comprising a generally closed housing including a bottom portion, particulate material and air inlet means and air outlet means, the inlet means and air exhaust means being above the bottom portion and the air outlet means being adapted to be connected with air suction generating means. Means within the housing screen air flow between the inlet means and the air outlet means while particulate material gravity falls to the bottom portion. Particulate material outlet means is separate from the inlet means and is associated with the bottom portion of the collector. Means are provided for conveying material from the bottom portion to a material outlet means, the material outlet means including means which prevents air from entering the housing during start-up operation of the device and which, in conjunction with some material being conveyed to the outlet means for discharge outside the device, creates an air lock to substantially prevent air entering the housing through the material outlet means while material is being collected and discharged.
