Transmission device for vertical header of harvester, vertical header and harvester

Abstract

The present relates to the field of agricultural machinery and particularly relates to a transmission device for a vertical header of a harvester and the harvester. The transmission device for the vertical header of the harvester comprises a driving shaft, the driving shaft is connected with an input shaft of a gearbox through a first chain; one end of an output shaft of the gearbox is connected with a driven shaft close to a second output port through a second chain, and the other end of the output shaft of the gearbox is connected with one side of a speed-changing and gear-shifting control mechanism; and a first output of the driven shaft is connected with an ear picking and feeding device, a second output port is provided with an overrunning clutch, and the overrunning clutch is connected with a grass discharging, pushing and conveying device. The gearbox is arranged on a main transmission line of the transmission device, so that multi-stage rotating speed adjustment of header transmission is realized and reversal of the vertical header can be realized.

Description

technical field [0001] The present disclosure relates to the field of agricultural machinery, in particular to a transmission device for a vertical header of a harvester and the harvester. Background technique [0002] The vertical header of the ear and stem corn harvester has wide adaptability. According to the different varieties, planting modes and harvesting habits in the northern and southern corn regions, the vertical header can basically be fully adapted. However, for very special varieties in special areas, such as harvesting early spring corn or sweet corn in Hebei, the vertical header needs to adjust the speed before harvesting. If you need to adjust the speed of the vertical header, you need to adjust the main The operation of replacing the transmission sprocket of the transmission line is more complicated; in addition, if the feeding amount of the vertical header is too large during operation, the header picking mechanism may be blocked, and it needs to be shut d...

Problems solved by technology

However, for very special varieties in special areas, such as harvesting early spring corn or sweet corn in Hebei, the vertical header needs to adjust the speed before harvesting. If you need to adjust the speed of the vertical header, you need to adjust the main The operation of replacing the transmission sprocket of the transmission line is more complicated; in addition, if the feeding amount of the vertical header is too large during operation, the header picking mechanism may be blocked, and it needs to be shut down when cleaning the blockage, and then It is time-consuming, labor-intensive and dangerous to manually pull out the clogged material on the header. In view of the above situation, it is urgent to equip the vertical header of the ear-stem corn harvester with a device that can adjust the speed and reverse.
