Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a single-row lifting corn harvester. Background Art

[0002] In the existing field of small agricultural machinery, during the corn harvesting process, a single-row corn harvester is usually used to harvest corn in small plots. This type of machinery is small and flexible, suitable for use in small plots of land, and its work efficiency is much higher than manual harvesting.

[0003] However, during the use of this type of existing small-scale equipment, due to structural design defects, there are many functional disadvantages, which are reflected in: 1. The existing mechanical corn peeling structure of this type is simple. During the peeling operation, the corn cannot be completely separated from the epidermis, resulting in problems such as incomplete peeling, and the subsequent threshing operation cannot be carried out smoothly; 2. The height of the corn header is constant. When harvesting corn, because the equipment is directly fixed on a small traction machine, there are usually only two states, namely the harvesting state and the non-harvesting state. In the harvesting state, the height of the header is constant and cannot adapt to corn harvesting at different heights. If the initial state is not adjusted properly, the root will be too high, affecting the planting of the next crop season; 3. After the corn husk is peeled off, if the corn husk is very humid, the corn husk will be blocked under the peeling module, affecting the normal operation of the equipment.

[0004] In response to the technical problems raised above, it is very necessary for technical personnel in this field to design a single-row lifting corn harvester, which can flexibly adjust the height of the cutting table, improve the function of the peeling module, improve the peeling efficiency, and effectively prevent corn husks from blocking the discharge channel under the peeling module.
