Harvesting table of corn harvesting machine

Abstract

The invention relates to a harvesting table of a corn harvesting machine. The harvesting table comprises a header frame body, an ear picking mechanism, an auger mechanism; the ear picking mechanism isarranged on the header frame body through ear picking driving shafts; the auger mechanism is arranged on the header frame body through an auger driving shaft; two ends of the header frame body are respectively provided with a left input shaft driving assembly and a right input shaft driving assembly; the ear picking driving shafts comprise a left ear picking driving shaft and a right ear pickingdriving shaft; a left hydraulic motor is connected with a left input shaft; the left input shaft end is provided with a first left driving chain wheel and a second left driving chain wheel; the firstleft driving chain wheel is connected with a driven chain wheel at the left ear picking driving shaft end through a transmission chain; the second left driving chain wheel is connected with a driven chain wheel at the auger driving shaft end through a transmission chain; a right hydraulic motor is connected with a right input shaft; and the right input shaft end is provided with a right driving chain wheel and is connected with a driven wheel at the right ear picking driving shaft end through a transmission chain. According to the harvesting table, a left and right double-hydraulic transmission mode is adopted, and variable-speed adjustment of the operating speed of a header can be realized.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a corn harvester harvesting platform. Background technique [0002] The header is a key component to complete the ear picking function of the corn harvester. It mainly completes the introduction of corn stalks from the grain divider into the cone, and at the same time, the stalks are pulled up by the reel chain. With the advancement of the machine and the rise of the reel chain, the stalk pulls down faster and faster. Under the action of the ear picking plate, the gap is smaller than the diameter of the ear. Therefore, the fruit ear is picked up due to resistance here, and is lifted by the reel chain to the horizontal conveying auger. The existing headers are usually driven by chains and belts, and the transmission speed is constant, that is, the harvesting speed is constant, which cannot adapt to different harvesting states and harvesting effects, and may easily cause cro...

Problems solved by technology

The more rows there are, the longer it takes to adjust the ear picking boards. Therefore, it is necessary to design a device that can be adjusted uniformly to solve the tedious and time-consuming problem caused by adjusting the ear picking boards one by one.
