Grass discharging mechanism, ear and stem harvesting table and corn harvester

Abstract

The invention relates to a grass discharging mechanism, an ear and stem harvesting table and a corn harvester. The grass discharging mechanism comprises a grass discharging auger; the grass discharging auger comprises an auger shaft and multiple sections of auger blades; each section of auger blade is spirally fixed to the outer wall of the auger shaft; and the multiple sections of auger blades are arranged at intervals and used for conveying weeds to any ends of the auger blades respectively. The grass discharging mechanism has the advantages that the auger blades are arranged at intervals, after weeds at one auger blade are conveyed to any end through the corresponding auger blade, the weeds fall down under the action of gravity at the position between the two auger blades and cannot move to the next weed inlet position along the grass discharging auger, and therefore the situation that the weeds are accumulated and blocked at the grass discharging auger is effectively avoided.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a grass discharge mechanism, ear stem and harvesting platform and a corn harvester. Background technique [0002] The header is the mechanism at the front of the harvester that cuts the crop and feeds it to the rear. For the corn harvester, after the corn crop enters the feeding channel of the header, the lower part of the crop is cut off by the cutter at the lower part of the header, and the crop is fed backward along the feeding channel, and the ear is separated from the stalk when passing through the ear picking roller. The ears fall to the ear conveyor belt, and the stalks continue to be transported backwards to the stalk crushing device. Among them, the front side of the ear conveyor belt is provided with a front baffle, and the front baffle is provided with multiple feeding gaps, and the lower end of the stalks passes through the corresponding Feed the notch and feed ...

AI Technical Summary

Problems solved by technology

[0003] The existing panicle stalk and harvesting platform have a large distance between the cutter and the weed auger. After the stalk is cut, the upper part is pushed backward by the reel chain. , when the bottom of the stalk touches the forward-rotating weed auger, a forward reaction force is generated, which is easy to break the stalk

In particular, there is no weed auger in the front section of the existing vertical roller mower, which causes the weeds at the bottom of the stalk to enter the feeding gap after the stalk is cut, and the weeds are easy to block the feeding gap

[0004] The weed discharge auger in the existing cutting platform is only the auger with continuous spiral blades, the weeds are all conveyed to one end, and the weed discharge efficiency is low, and the weeds below the multiple reed feeding channels gradually accumulate to one end, which is easy to block
