Abstract
The invention discloses a self-propelled corn combine harvester, which comprises a self-propelled chassis, an ear picking-up table, a plant lifting device, a peeling mechanism, a threshing mechanism, a storage and transport tank, an ear conveying mechanism and a driving mechanism, wherein the ear picking-up table is arranged in the front of the self-propelled chassis; the plant lifting device is arranged above the ear picking-up table; the back of the plant lifting device is connected with the ear conveying mechanism; the ear conveying mechanism conveys ears to the peeling mechanism, the threshing mechanism and the storage and transport tank which are in sequentially stepped arrangement through a first guide groove; the driving mechanism drives the self-propelled chassis to move forward and drives the ear picking-up table to pick up the ears in fit with the plant lifting device; and the ears are conveyed to the peeling mechanism and the threshing mechanism sequentially by the ear conveying mechanism to be peeled and threshed first and then are sent to the storage and transport tank to be stored and transported. The self-propelled corn combine harvester realizes that the operations of picking up the ears, picking up the ears and peeling and picking up the ears and threshing are performed respectively according to different corn varieties, different planting agricultural techniques and different water contents.
Description
Technical field
The present invention relates to the combined machine of harvesting corn in the agricultural machinery, particularly a kind of multifunctional self-propelled corn combine.
Background technology
The corn combine toolization is one of China's agricultural engineering key project.Corn is China the third-largest crops after paddy rice, wheat, and the crops results are important links in the agricultural development.Now, wheat mechanical harvest rate has reached more than 85%, and the paddy machinery utilization percent also reaches about 60%.And corn mechanical harvest rate is less than 4%.Artificial harvesting corn need be paid heavy physical labor and long time, and along with corn the improving constantly of status in national economy, cultivated area constantly enlarges, and the corn combine toolization has just been mentioned very important agenda.
At present, developed country's harvest corn has been realized mechanization substantially in the world, as the U.S., France, Germany etc., their corn combine is based on large-scale, self-propelled, the 1293 type corn harvesting benchs that the large-scale corn combine of producing as U.S. John deere company is equipped with, but once harvesting corn reaches 12 row, ceding of Taiwan overall width reaches about 8m, the power of the motivation of allotting reaches 250KW (340 horsepowers), and the production efficiency height is fit to ranch, big plot operation.Along with the continuous development of scientific and technological level, external corn combine develops towards maximization, specialization, versatility, high-adaptability, intellectuality and hommization direction.Along with the development of global positioning system, geographic information system and remote sensing technology, the intelligent degree of corn combine is more and more higher.
Intellectual communityintellectualized village's corn combine is in the results process, the seed of sub-district can be weighed, measured and measures the moisture content of seed, calculate that dry weight is stored simultaneously and calculate rapidly and print the yield data of sub-district, again mean, the coefficient of variation and the significance of whole test small plot experiment are all calculated by calculator, be aggregated into table simultaneously.The combined harvester of producing has been installed the output detector, can draw out the histogram of each zones of different output of farm behind harvest corn.
In addition, in the performance of considering to develop skill, more pay attention to hommization, handling, the comfortableness of driving and safety.For improving driver's condition of work, self-propelled corn combine harvester generally is equipped with modern airtight driver's cabin.Air-conditioning is installed in the driver's cabin, has improved driver's comfortableness, prevented the fatigue that environment badly causes, increased safety.
But the corn combine of developed country is not suitable for the popularization of China's maize harvesting mechanization:
One, China's corn planting belt is vast in territory, and is various in style, plantation agronomy (as line-spacing, vegetative period, harvest time etc.) utmost point disunity.
Its two, external large-scale corn combine costs an arm and a leg, and also is not suitable for the present purchasing power situation of China peasant.
They are three years old, the ear harvesting bench of external corn combine adopts " board-like ear-picking unit " more, and during this kind device harvesting corn, corn stem fractures, carries when plucking fringe the fringe handle easily and can not peel off the pericarp of corn ear, cause the percentage of impurity height, dispose powerful cleaning and the impurities removal apparatus for peeling off.
More than 3.2 hundred million mu of China's maize sown area calculates by present 4% machine yield, and nearly 300,000,000 mu of needs mechanized harvests are still arranged,
As seen the market of China's corn combine is very big, and the development level of the national corn combine identical with China region lags far behind China in the world, and also there is very large space development the corn combine international market.
In recent years, because the enforcement of national agriculture, rural areas and farmers policy, rural economy develops rapidly, peasant's affluence, rural laborer's increment, peasant's an urgent demand and have the ability to accept corn harvest mechanization; Through making great efforts for many years, development department develops the corn combine that meets China's harvest corn substantially, has arrived the popularization stage now.
Because suspension type corn combine price is lower, and in non-harvest corn season, corn combine can be pulled down from tractor, tractor can carry out other operations, is fit to the current needs of vast farmers.At present, the suspension type corn combine occupies certain market.But, the suspension type corn combine is because the limitation of structural configuration, the type that existing suspension type corn combine is ripe, can only finish and take corn ear and stem stalk processing (chopping and returning), integration of operation for fruit ear peeling, threshing can not finely be finished, the producer that has is configured in the corn ear debarker on the suspension type corn combine, not only peeling effect of result is undesirable, owing to make complete machine structure complicated, the increase of corn ear debarker failsafe link has influenced the operation of complete machine.
Along with the reinforcement of China to corn combine research dynamics; the realization that agricultural is managed on a fairly large scale; the peasant requires more and more stronger to corn ear peeling, threshing operations mechanization; because the structure of self-propelled corn combine harvester has enough spaces to arrange fruit ear debarker and thresher, self-propelled corn combine harvester will replace the status of suspension type corn combine in market.
The type of the existing self-propelled corn combine harvester comparative maturity of China has two kinds substantially, a kind of is that harvesting-platform is selected " board-like ear-picking unit " for use, fringe, peeling operation are also just plucked in the operation of finishing, because the high percentage of impurity of board-like ear-picking unit, not only the load to facility increase impurities removal makes the debarker structure huge, and plugging fault takes place easily; A kind of is that harvesting-platform is selected " roll-type ear-picking unit " for use, and roll-type ear-picking unit percentage of impurity is low, but chews corn ear easily; Above-mentioned two kinds of types also exist common shortcoming, are exactly all not have flexibility and mobility, particularly when the initial stage of harvesting corn, the corn moisture content was higher, owing to peeling, thresher cisco unity malfunction influence the complete machine operation.So existing self-propelled corn combine harvester does not satisfy the requirement of harvest corn entire mechanization.
