Description
Technical field
The utility model belongs to corn threshing technical field, particularly relates to a kind of corn kernel installed threshing separator and has the combined harvester of this separator.
Background technology
At present, the cereal crops kind of China is many, distribution is wide, areal variation is large.Wherein again with wheat, paddy rice, corn distribution the most extensively, output is maximum, and three closes and accounts for more than 86% of national total output of grain.Corresponding combined harvester also divides wheat combine, rice combine, corn combine etc., under the impact of international harvest machinery technological progress trend and the promotion of Speeding The Development of Modern Agriculture new demand, China's harvest machinery product technology starts by middle-size and small-size, simple function to multi items, multi-functional development.
In fact due to the similitude of crop, combined harvester just take into account the general problem of rice wheat when designing, and is successfully applied to market, and by the parts thereof that changes the outfit, rice-wheat combine harvester also can take in soybean, rape concurrently.Wheat berry is harder, and the clever shell of parcel is more loose, easily deviates from, sheller unit many employings drum with rasp bars by the method for rubbing and hitting, and drum with rasp bars working performance is better, and original text grass is disconnected broken less; Grain of rice shell parcel is comparatively tight, but shell is more fragile, easily broken, is advisable with the method threshing curried and hit.
But because corn crop characteristic and seed size shape etc. differ greatly with wheat, paddy rice, therefore how realizing rice-wheat combine harvester becomes a large technical barrier to taking in concurrently of corn crop.Current Joint reaping machine is mainly divided into straw walker, single longitudinal axial flow, two longitudinal axial flow, transverse-axis-flow 4 product technology platforms by the difference of installed threshing separator.Then main based on straw walker, single longitudinal axial flow, two longitudinal axial flow platform abroad, straw walker remains the Mainstream Platform of combine harvester as a kind of traditional threshing isolation technics, but is not suitable for directly receiving for doing corn kernel meet grain threshing separating property on project organization while.
Simultaneously, China's corn machine is received and is mainly contained two kinds of modes: one is adopt harvesting debarker take fruit ear and peel off bract, fruit ear after airing by husker sheller threshing, this mode functional reliability is better, but all swivel links are many, grain loss is comparatively large, adds cost and is unfavorable for large-scale production; One is that this mode efficiency is high, and improves the availability of reaping machine with corn combine by the direct harvesting corn seed of the annexes such as separating mechanism that change the outfit, and therefore, direct harvesting corn seed more and more becomes a kind of trend that corn machine is received.
Two types are mainly contained at present: one is with patent: 201320875300.5 is the grid type threshing concave plate of representative for the threshing concave plate in corn kernel installed threshing separator, the round steel being 6-16mm by the diaphragm plate intersection diameter that band steel is shaping forms, sieve aperture is rectangle, sieve aperture rate is about 40%-70% (the sieve aperture gross area accounts for the ratio of the threshing concave plate gross area), threshing performance is high, screen rate is high, wide adaptability, but diaphragm plate has corner angle and protrudes threshing concave plate body, and then cause percentage of damage higher, when in receiving especially for kernel direct, corn kernel moisture content is higher, and the separating mechanism intensity of this structure is poor, easy deformed damaged, cause maintenance cost high, one is with patent: 201120234108.9 is the punched holes type threshing concave plate of representative, and hole is circular hole or strip hole, and aperture is 15-17mm, sieve aperture rate is about 32%, manufacturing process is simple, and threshing performance is high, and percentage of damage is low, but it is poor that corn kernel passes through property, screen rate is low, and whole threshing concave plate and miscellaneous part are connected as a single entity, stability and servicing ease poor, and cylinder-concave clearance is non-adjustable, uses and there is larger limitation.
And mainly contain three types for the threshing tooth in corn kernel installed threshing separator at present: one is plate cutter tooth, capture and curry flailing action strong, when crop feeding is uneven, adaptability is better, but larger to corn kernel injury; A short and thick conical tooth, less to corn kernel injury, but threshing efficiency is lower; One is threshing fluted disc, and hit threshability comparatively strong, threshing efficiency is higher, but reliability is lower.Require that corn kernel moisture content is less than 18% during above-mentioned three kinds of threshing tooths work, if moisture content is higher than this level, greatly will increase the percentage of damage of seed; The threshing cylinder be applied on combined harvester mainly contains three types: one is nail tooth drum, has stronger Grasping skill, strong adaptability when crop feeding is uneven, and threshability is strong; One is drum with rasp bars, threshing better performances, but when crop feeding is uneven, adaptability is poor, easily blocks cylinder; One is bar dental roller, and by fashion of extrusion, corn ear is squeezed broken and seed threshing, threshing better performances, percentage of damage is lower; The working performance of nail tooth drum and drum with rasp bars is stablized, but all there is the high problem of seed damage rate, and the threshing tooth of bar dental roller is quarter butt tooth, belong to machined piece, upper end is spherical cylinder, and lower end is by Screw assembly on ratch, and its manufacture difficulty is larger, power drain is large, production and application cost is higher, and existing barrel is spliced, is spliced to form by multi-sheets, manufacture difficulty is large, and dependability is poor.
