Impurity removal device of corncob lift conveyer of corn harvester

Abstract

The invention relates to an impurity removal device of a corncob lift conveyer of a corn harvester. An intermediate shaft is arranged at the outer back of the upper side of a second frid through a mounting rack, the intermediate shaft stretches into a shaft end at the inner side of the second frid to fix a lifting lever, and an intermediate chain wheel is arranged on the other shaft end of the second frid. A rotating shaft is assembled at the outer front of the upper side of the second frid through a tensioning support, a tensioning chain wheel is arranged at a shaft end of the rotating shaft, and the intermediate chain wheel, the tensioning chain wheel and a power take-off chain wheel at a shaft end of a driving shaft are meshed with a closed transmission chain. An impurity removal shaft is arranged on a first frid and the second frid, and poking plates with poking teeth are fixed on the impurity removal shaft, a power input chain wheel is arranged at a shaft end of the impurity removal shaft, and the power input chain wheel is meshed with the transmission chain in an outer mode. Straw and other impurities horizontally stacked at an inlet end of the corncob lift conveyer are poked to the lifting direction of the lift conveyer by the lifting lever of the intermediate shaft and then sent to a lifting part to convey the straw and other impurities out by the poking plates of the impurity removal shaft. The impurity removal device of the corncob lift conveyer of the corn harvester is reasonable in structure, simple to manufacture and reliable to use.

Description

technical field [0001] The invention relates to harvesting of corn, in particular to a miscellaneous discharge device of an ear elevator of a corn harvester. Background technique [0002] The corn ear lifting device is an important part of the corn harvester, which lifts and transports the corn ears picked by the ear picking roller to the peeling mechanism or the granary. And in the corn harvesting process, a large amount of sundries such as corn leaves and slightly stalks are entrained in the picked ears, so the reliability of the corn ear lifting device is related to the success or failure of the automatic harvesting of corn. In order to solve the problem that a large amount of sundries such as corn leaves and stalks are carried in the ear, which brings inconvenience to the lifting of the ear, the CN102362570A Chinese invention patent application published by the applicant on February 29, 2012 discloses the "corn harvester". The miscellaneous device of the fruit ear eleva...

AI Technical Summary

Problems solved by technology

However, during use, it was found that the corn stalks are light and supported by the ear flowers, and it is difficult to carry them into the miscellaneous discharge device. The corn stalks are piled up horizontally at the entry end of the ear elevator, causing the moving parts of the ear elevator to be jammed.
