Abstract
The invention discloses a plate-type corn ear picking structure, which comprises a plurality of high ear picking mechanisms and low ear picking mechanisms which are arranged in a high-low adjacent mode. Meanwhile, the ear picking mechanisms of the prior plate-type ear picking header are all on the same horizontal plane, and a dead angle for harvesting is formed between every two adjacent ear picking mechanisms; according to the corn harvester, the two adjacent ear picking mechanisms are arranged in a staggered manner, so that the reel chains can be covered in a staggered manner, the ear picking mechanisms of the whole header are arranged at intervals in a high-low manner from left to right, and compared with the traditional plate-type ear picking mechanisms, corns in front of the header can be harvested through the reel chains. Can effectively reduce the loss rate of the corn when the corn is harvested.

Technical Field
The invention belongs to the technical field of agricultural machinery, and particularly relates to a plate-type corn ear picking structure.
Background
A part of an area (such as a circular area in a figure I) which is not suitable for harvesting is arranged between each row of the existing plate-type ear picking header, and if corns are planted in the area, the corn stalks are gathered towards the middle by the divider when the harvester harvests, and in the process, the corn stalks are likely to be pushed down by the divider due to overlarge transverse position deviation, so that harvesting operation cannot be finished.

Furthermore, a transmission shaft is arranged on the side surface of the transmission case, and the adjacent high ear picking mechanisms and the adjacent low ear picking mechanisms are connected through the transmission shaft.
Furthermore, the tail end of the snapping frame is connected with a mounting frame.
The operation principle is as follows: the power is transmitted from the transmission case to drive the two stem pulling rollers and the two reel chains 3 to rotate, when the left stem pulling roller rotates clockwise when the left side is seen from the front and the back, the right stem pulling roller rotates anticlockwise when the right side is seen from the front, and when the left reel chain rotates anticlockwise when the right side is seen from the top, the right reel chain rotates clockwise. When harvesting, the corn stalk is firstly poked into the middle positions of the left and right stalk pulling rollers by the seedling poking chain 3, the whole corn stalk is pulled downwards under the opposite rotation of the left and right stalk pulling rollers, the corn ear also moves downwards at the same time, the corn ear is blocked by the ear picking plate 5 after falling to a certain height, the downward movement cannot be continued, the corn stalk is continuously pulled downwards under the action of the stalk pulling rollers, the corn ear is disconnected with the corn stalk at the moment, the corn ear is remained above the ear picking plate 5, and then the seedling poking chain 3 is continuously poked backwards to enter the subsequent conveying device to finish harvesting
Has the advantages that: in the invention, the dividing device is replaced by the reel chain, the reel chain is lengthened and expanded outwards, and the corn stalks are pulled towards the middle by the reel chain during harvesting, so that the corn stalks are pulled into the ear picking plate in the middle of the ear picking mechanism before the corn stalks are fallen down, the corn ears are picked, and the harvesting is finished; meanwhile, the ear picking mechanisms arranged in a staggered manner cover all harvesting dead zones, and corns in front of the cutting table can be harvested through the reel chains during harvesting. Has the following advantages: (1) simple structure and low production cost. (2) Effectively reduces the loss rate of the corn when the corn is harvested. (3) Compared with a divider, the reel chain has better feeding effect, so that the harvesting efficiency is higher.
