The device has reasonable design, can improve the corn ear picking and harvesting efficiency, avoids the blockage of corn stalks on equipment, improves the corn ear picking efficiency in multiple aspects and is beneficial to popularization. However, the device has some defects in the using process, and in the process of harvesting the fruit corns, because of the characteristics of freshness, brittleness and tenderness of the fruit corns, the ear picking plates can easily extrude water out of grains at the roots of the corns during ear picking, so that the grain breakage rate of the corns is high; in the fruit corn ear picking process of the harvester in the prior art, only 10% of corn ears are qualified, the phenomenon of kernel breakage is avoided, and the qualified requirement is met. The prior art obviously has inconvenience and defects in practical use, so that improvement is needed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to above not enough, provide a corn harvester plucks ear of grain board, can reduce the seed grain percentage of breakage of plucking ear of grain in-process corn ear, reduce the damage to corn ear, guarantee the integrality of corn ear.
For solving the technical problem, the utility model discloses a following technical scheme: a kind of
An ear picking plate of a corn harvester comprises ear picking plates which are symmetrically arranged, wherein each ear picking plate comprises a horizontal part, an arc part and a round rib; one side of the circular arc part is connected with the horizontal part, and the edge of the other side of the circular arc part is fixedly provided with a circular rib through welding; the round ribs are smooth round ribs with the diameter of 10 mm; and stem pulling rollers which are symmetrically arranged are arranged below the ear picking plates, and the vertical height between the central line of the stem pulling rollers and the central line of the round ribs is 63-77 mm.
Furthermore, gaps for picking ears are arranged between the round ribs.
Further, the circular arc part is sunken downwards, and the circular arc part and the horizontal part are integrally formed.
Furthermore, one end of the horizontal part, the arc part and the round rib is provided with a chamfer with the same angle, and the other end of the horizontal part, the arc part and the round rib are flush and mounted on the fixed seat.
The utility model adopts the above technical scheme after, compare with prior art, have following advantage:
the ear picking plate provided by the utility model can prevent the grains at the root of the corn from being squeezed out of water, greatly reduce the seed crushing rate at the root of the fruit cluster of the fruit corn, reduce the damage to the corn cluster and ensure the integrity of the corn cluster; after the ear picking plate is adopted by the harvester, in the fruit and corn ear picking process, 90% of corn ears have no phenomenon of broken grains, the qualified rate reaches 90%, and compared with the qualified rate of 10% in the prior art, the yield is obviously improved, and the agricultural production and income increase can be promoted.
The present invention will be described in detail with reference to the accompanying drawings and examples.

Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
Example 1 ear plucking plate of corn harvester
As shown in fig. 1 and fig. 2, the utility model provides an ear picking plate of a corn harvester, which comprises ear picking plates 1 symmetrically arranged, wherein the ear picking plate 1 comprises a horizontal part 101, an arc part 102 and a round rib 103; the circular arc part 102 is downwards sunken, one side of the circular arc part 102 is connected with the horizontal part 101, the circular arc part 102 and the horizontal part 101 are integrally formed, and a circular rib 103 is fixedly welded at the edge of the other side of the circular arc part 102; the round ribs 103 are smooth round ribs, and the diameter of the round ribs 103 is 10 mm; gaps 2 are arranged between the round ribs 103.
