Patent CA-2032836-C (CA)
Title: Harvesting machine
Inventor: SHUKNECHT LEE N
IPC: A01D33/02
Filed: 1990-12-20
Granted: 1993-12-14
Abstract: HARVESTING MACHINE      Abstract A harvesting machine is especially adapted for automatic topping and loading of crops, such as onions. The crops are gathered from the field and elevated on a conveyor to a region adjacent to which a topping device (a sickle) is disposed.  The conveyor has openings to permit the passage of air which is blown from a blower. The openings are sufficiently narrow to support the crop while allowing rocks, clumps and other debris to drop therethrough. The blower is offset from the topping region.  A duct extends tangentially and upwardly from the blower to direct a laminar (non-turbulent) flow of air through the conveyor openings for extending the tops.  The duct has a wall at the bottom thereof which faces the region. This wall has a passage, preferably with louvers which extend generally vertically.  A negative pressure is developed adjacent to these louvers and a generally laminar flow of air passes upwardly through the louvers and enhances the laminar flow through the conveyor in the region where topping occurs.  The rocks, clumps and other debris fall downwardly through the louvers and out of the machine thereby preventing damage to the blower.
