Description
Technical Field
The utility model belongs to the technical field of agricultural machine, concretely relates to six arris roller snapping plate combination formula maize results header.
Background
The corn harvesting is the most onerous link in the corn production, the manual harvesting efficiency is low, the labor amount is large, a large amount of labor is required to be invested, and the investment of the corn harvesting labor amount accounts for 55% of the whole corn production link. The Huang-Huai plain spring summer sowing corn area is a two-cropping planting area in one year, the corn is harvested in the third and fourth seasons, the mature corn needs to be harvested in time for ensuring the timely cultivation of the next crop, and the corn harvesting time is short, the task is heavy and the farming season is robbed. With the rapid development of social economy and the mass transfer of rural labor force, the mechanized harvesting of corn is an urgent problem to be solved in order to ensure the food production safety in China.
The header is a key working part of the corn harvester, and the working quality of the header directly influences the working quality of the corn harvester. The header can be used for picking corn ears with different corn stalk diameters and different ear-bearing heights, and the ear picking operation should reduce seed loss and seed crushing as much as possible under certain working efficiency. The most common mode of the existing corn harvesting header is a snapping roll type, wherein spiral ribs are connected with snapping smooth rolls in a welding mode, and the spiral ribs work in a staggered mode through relative rotation between the snapping rolls. The spiral rib plays a role in transporting and blocking the corn ears for the corn straws, the corn ears are forcibly stretched and pulled downwards through the snapping rollers and the extrusion of the spiral rib on the corn straws, so that the corn ears and the straws are separated to complete the snapping process, and the mechanical essence of the corn ears and the straws is to complete the snapping process through stretching and extrusion. The ear picking mode is a mode adopted by most ear picking mechanisms at present, and due to the fact that the ear picking rollers are provided with the spiral ribs, at least one rib is guaranteed to act on the corn ears in the working process, and the small corn ears can fall between the two smooth rollers to cause damage. In addition, the rib also causes damage to the corn ear due to secondary grabbing when grabbing the corn ear, the impact force is in direct proportion to the height of the rib and the rotating speed of the snapping roll, the faster the rotating speed of the snapping roll is, the higher the rib is, and the higher the possibility of causing damage to the corn ear is. At present, most of researches on a snapping roller type snapping device focus on the aspects of snapping roller length, placing mode, power loss reduction and the like, but most of researches on increasing the straw grabbing capacity of the snapping roller do not fundamentally change the mode that the snapping roller is provided with a spiral rib, so that the problem that the damage possibility of the corn ear is still caused by secondary collision still exists. It performs poorly in practice. At present, the corn harvesting header which can meet the requirements of high efficiency and low loss as much as possible needs to be researched and developed urgently.
