Pneumatic blowing device for header of combine harvester

Abstract

The invention discloses a pneumatic blowing device for a header of a combine harvester, which comprises a header body, a servo electric cylinder and an air collecting pipe. The header body is interconnected with a pneumatic blowing assembly, and the air collecting pipe is interconnected with a tail end framework. The air collecting pipe is interconnected with a lower saddle and a U-shaped clamp, and the lower saddle is arranged below the U-shaped clamp, and the bottom end of the lower saddle is interconnected with the top end of an air nozzle. A wind collecting bushing is interconnected with areinforcing bent pipe, and the reinforcing bent pipe is interconnected with a ventilation straight pipe, and the reinforcing bent pipe and the ventilation straight pipe are both interconnected with aclamp. The ventilation straight pipe and a telescopic hose are connected with each other, and the telescopic hose and the clamp are connected with each other. According to the pneumatic blowing device for the header of the combine harvester, the novel structural design is adopted, so that the device can recover the loss before cutting, the power consumption is low and the efficiency is high. A recovery structure can be adjusted by an adjustment structure and the wind force is enough to recover pellets more efficiently and improve the recovery effect.

Description

technical field [0001] The invention relates to the technical field of agricultural harvesting machinery, in particular to a pneumatic blowing device for a header of a combine harvester. Background technique [0002] The combine harvester is a commonly used agricultural machine. It is mostly used for harvesting crops. It can complete the harvesting, threshing, separating stems, removing debris and other processes of cereal crops at one time. It can directly obtain grain from the field, so it is widely used. [0003] When the traditional combine harvests mature crops, due to the mutual contact between the reel teeth and the crops, a large number of ears of grain are collided and lost before cutting, that is, the loss before cutting. This part of the loss often accounts for 30% of the total loss. % or more, especially when harvesting mature rapeseed, the loss of this part reaches 50% of the total loss. When rapeseed is combined harvesting, the maturity of rapeseed reaches more...
