[0002] The existing corn picker has several ways in the process of conveying corn to the granary after peeling by the peeling machine: 1, the corn with bracts is directly pushed into the granary after peeling by the peeling machine, without any intermediate device, which has many shortcomings, because of the absence of the intermediate device, the corn is directly dropped from the peeling machine into the granary, which forms a triangle on the cross section of the granary, the corn on the side close to the peeling machine is higher and higher, resulting in that a lot of effective space in the granary cannot be utilized, the frequency of unloading is increased, and the efficiency is low. 2, a throwing roller is installed between the peeling machine and the granary, the corn from the peeling machine is thrown into the granary through the throwing roller, which solves the problem that the corn is stacked on the side of the peeling machine, but because the speed of the throwing roller is high, the initial speed of the corn is high when thrown out. It is easy to hit the side wall of the granary with a certain speed, and in this case, there is a certain probability that the corn knocks off the kernels, damaging the corn. In addition, the highest point of the corn that can be stacked after entering the granary is at the position of the peeling machine in the two ways.

[0003] In order to improve the space utilization rate of the corn picker granary and reduce the phenomenon of knocking kernels of the corn, a new way is needed to lift the corn from the peeling machine to a position higher than the outlet of the peeling machine and enter the granary at the intermediate position of the granary to improve the efficiency.
