Description
Technical Field
The utility model relates to a novel adjustable cutting knife structure of corn harvester.
Background
Grain corn harvesting is that a machine finishes a plurality of operations such as ear picking, stacking and stalk returning once to the field once to the corn after the corn is waxed, and the difference between fresh corn harvesting and grain corn harvesting lies in that the fresh corn harvesting is carried out when the corn is milk-ripe.
The Chinese grain corn harvesting technology is reported to be mature, and the main process flow is as follows: ear picking is carried out by a grain corn harvester under the growth state of corn (called stalk picking), and under the action of an ear picking roller and an ear picking plate, the ear stem is pulled apart. The cutter cuts the straws from the root parts and then enters the crushing mechanism to be crushed, and the crushed straws naturally fall to the ground. Then the ears are transported to the field, peeled by a peeling machine, and threshed after being aired. According to different regional conditions and farming modes, the countries respectively adopt corresponding harvesting modes: in the united states, canada and western europe, because the moisture content of corn grains is low during harvesting, a corn header is generally replaced on a grain combine harvester, a direct threshing harvesting mode is adopted for direct storage, and the grain combine harvester is adopted for large area (for direct harvesting of the corn grains); in russia, ukraine and eastern Europe countries, because the moisture content of corn grains is high in the harvesting period and the corn is not suitable for direct threshing, a special corn combine harvester is adopted to harvest corn ears, and a special corn harvesting machine (harvesting corn ears) is widely applied, so that the combined operation of ear picking, ear peeling and ensiling can be carried out, and the combined harvesting of stems and ears is realized. The grain corn harvester mainly comprises a single-row type, a backpack type, a traction type, a multi-row self-propelled type, a stem and ear harvesting type and an unparallel type, and is mainly characterized by the backpack type.
More particularly, compared with the grain corn harvesting technology, the mechanical harvesting of fresh-eating corn in China is only a grope stage, and a large amount of technical blanks still exist, and as the labor cost is higher and higher, the production area of each fresh-eating corn tends to be mechanically developed more for reducing the cost.
The corn harvester for both stalk and ear is composed of: the harvesting machine mainly comprises a header, an elevator, a peeler, a gap bridge, a chopper, an ear box and a grass box, wherein the feeding function of the header directly influences the harvesting performance of the whole machine and is a key part in the whole machine. For a corn harvester with stalk and ear harvesting, the functions of picking up ears and cutting and recycling stalks are required to be simultaneously realized. The stalk and ear harvesting needs to recover the stalk, so a front cutter is needed. Cut off the stem stalk through the cutting knife in the feeding, then further with ear of grain and stem stalk separation, realize the ear of grain to take and the function that the stem stalk was retrieved, the cutting knife of the type maize picker is received to ear of grain on the existing market can't be adjusted in practical application, and the maize stem stalk is growing vigor different, so better feeding effect just can't be realized to the cutting knife of structural function singleness, can't freely adjust according to complicated operational environment, can't accomplish the feeding function well, further influence the results effect of complete machine, therefore, the adjustable cutting knife structure of a novel maize harvester should be transported and is given birth to.
