Description

Folding harvester header

Technical Field

The utility model relates to the field of agricultural machinery, in particular to a folding harvester header.

Background

In recent years, crop planting cost is continuously increased, planting benefit is continuously reduced, and development of crop industry is also under great pressure under the influence of rural labor force transfer and imported oil impact. The traditional production mode still depends on manual work, but the production cost is higher, the efficiency is lower, intensity of labour is big, the benefit is low, has hit numerous peasant household production enthusiasm. At present, the agricultural mechanization level of China is lower, the quantity of machines which can be put into actual production is less, the production efficiency of crops is limited, and the efficient production of agricultural mechanization is urgent.

Typically, harvester units are used to serve farms where the farm is a farm where tens of thousands of acres of land are available, either the john diel C230 harvester or a larger, plain import harvester, with a header that is very wide and cost prohibitive. While the host used was john diel 1075 harvester, and farm land was no longer in use. And one modified edge cutting machine can only finish the ridge harvesting task of more than 12000 mu of one division of the farm.

The traditional harvester device is a John diel 1075 combine harvester, when the harvester header is not biased, the edges can not be harvested when harvesting the ridge, and the small crawler harvester walks on the ridge when harvesting the ridge, so that the accident of turning over and death easily occurs. However, after the harvester header is modified into a common offset header, the offset header can cut 2.2 meters, and the ridges of the farm can basically receive edges, but the harvester header is very inconvenient to travel on roads and enter and exit the road due to the offset of the header. If one ridge harvester is not arranged on a farm for 12000 mu of land, a large amount of manpower is needed for harvesting, and the efficiency of labor and civil injury and financial recovery is low. And with small crawler harvesters, harvesting is dangerous. When the large crawler belt is harvested, the situation that the harvesting is not finished, only half of the large crawler belt can be harvested and the other half of the large crawler belt is wasted can occur.

Aiming at the problems existing in the prior art, the folding harvester header has important significance.
