Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.

Example 1:

as shown in fig. 1-3, an asymmetric ear breaking rod for corn harvesting provided by an embodiment of the present invention includes a pair roller assembly, the pair roller assembly includes a smooth roller 1 on one side and a knife roller 2 on the other side, a knife 3 is distributed on the knife roller 2, the knife 3 can be a knife blade or a knife plate or a tooth-shaped knife tooth or a lacing bar, such as a knife with tooth-shaped knife tooth in fig. 8, an ear breaking plate 4 is arranged in front of the feeding of the knife roller 2, the bottom of the ear 12 is prevented from contacting the knife roller 2 by guiding and blocking of the ear breaking plate 4, as shown in fig. 3, the corn stalk is conveyed into between the pair rollers by a conveying mechanism on the corn header, the handle end 11 of the ear 12 firstly enters into the gap 7 between the pair rollers, the ear 12 does not contact the knife roller 2 due to the blocking of the ear breaking plate 4, at this time, under the combined action of the knife 3 and the ear breaking plate 4, the handle end 11 of the ear 12 is broken, therefore, the corn ear breaking is realized, and the corn ear 12 cannot be damaged in the whole process.

The ear breaking plate 4 is an arc-shaped ear breaking plate, one end of the arc-shaped ear breaking plate extends to the position of the gap 7 between the rollers, the arc-shaped contact surface is more round, the ear breaking plate 4 can be further prevented from damaging the corn ears 12, in addition, the contact surface of the ear breaking plate 4 and the corn ears 12 can be subjected to buffering treatment, if the surface is provided with a rubber plate or a rubber layer and the like, the smooth roller 1 can also be a rubber roller, or the surface is also subjected to similar treatment, so that the smooth roller 1 can be prevented from damaging the corn ears 12, and the rubber roller has larger friction force, is not slippery and is convenient to feed.
