Abstract
The invention discloses a method and device for collecting field falling grains of an oilseed rape combine harvester. The problem that an existing oilseed rape combine harvester is large in harvest loss is solved. The method for collecting the field falling grains comprises the steps that oilseed rape grains in the falling process between straw in front of a header of the harvester are conveyed to a negative-pressure chamber in a collecting monomer to be collected through a collecting monomer inlet by utilizing negative-pressure airflow provided by a negative pressure fan, and the oilseed rape grains in the negative-pressure chamber of the collecting monomer are conveyed and collected to a selecting device on the tail portion of the harvester through a negative pressure channel in an air force conveying mode. The collecting device comprises a hanging frame capable of being connected with the header of the harvester in a hanging mode, a transverse negative pressure airflow collecting channel, the collecting monomer and a standing grain dividing and supporting plate. The hanging frame, the transverse negative pressure airflow collecting channel, the collecting monomer and the standing grain dividing and supporting plate are connected in sequence. The method is ingenious in concept, high in collecting efficiency and good in blocking removing effect. The device is simple in structure and convenient to operate, can be assembled on the common harvester header and effectively reduces the total loss ratio in the combine harvest of oilseed rapes, and meanwhile harvesting time is more abundant and more free.
Description
technical field [0001] The invention relates to an agricultural machine, in particular to a field shatter collecting device of a rapeseed combine harvester. Background technique [0002] Rapeseed is an important field crop. However, my country's rapeseed planting has been in the manual operation stage for a long time, and the current overall level of planting mechanization is still less than 10%. Among the many links of mechanical planting of rapeseed, mechanical harvesting is one of the most difficult links to achieve. Rapeseed has agronomic and biological characteristics different from rice and wheat, such as tall plants, numerous and intertwined branches, small grains, large distribution range of siliques, different ripeness and cleavage, which make mechanized harvesting suffer serious losses, and become the current mechanical harvesting industry. One of the most difficult field crops. Mechanized harvesting is divided into two ways: segmented harvesting and combined ha...
