Abstract
The utility model relates to an agricultural machine concrete crowdedly rubs formula corn threshing cylinder with the hands for flexible, is applicable to threshing of cereal such as maize, and it is mainly by spiral plate tooth (1), toper roller shell (2), flexible bar tooth constitutions such as (3). The utility model discloses on the basis of having carried out analysis, research to corn threshing power, the flexible bar tooth threshing cylinder that the similar rigid bar tooth of principle of threshing was threshed has been designed, show that the flexible bar tooth is threshed in the index, and threshing performance, the percentage of thresh and rigid bar tooth threshing cylinder are close through the contrast test result of threshing, percentage of damage, dirt percentage are showing and are being less than rigid bar tooth cylinder, and the effectual cereal of having protected receives the destruction that the rigid shock caused in threshing process.
Description
Technical field
This utility model relates to a kind of flexible crowded stranding formula corn thresher drum, belongs to agricultural mechanical field.
Background technology
Semen Maydis is as the cereal crops of China's cultivated area maximum, and 2014 Annual planting areas reach 0.37 hundred million hm2, in China
Grain-production in occupation of increasingly consequence.From the point of view of China's national situation and developed countries Maize Production history, beautiful
Rice sowing, harvesting, threshing realizes whole production process do mechanization operation, is to enjoy popular confidence and trend of the times.Wherein, threshing is Semen Maydis
Gathering in the crops vital link, the core of threshing system is threshing cylinder.Tradition threshing cylinder wide variety, has been summed up nail
Tooth-like, rasp bar formula and bow tooth formula etc., realize fruit ear threshing mainly by impacting, curry, squeeze the principles such as stranding.Tradition threshing cylinder is all
Rigidity effect, the shelling that the fruit grain taken off occurs, broken and underbead crack equivalent damage, have a strong impact on percentage of seedgermination.Remove
Outside this, the tradition strong vibration that produces at work of thresing machine and big noise, not only have impact on thresing machine machine life, to environment
Cause bigger pollution, also do not meet the requirement that current green agriculture produces.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of flexible crowded stranding formula corn thresher drum.
This utility model solves its technical problem and be the technical scheme is that described flexibility squeezes stranding formula maize sheller
Cylinder, by spiral lamina tooth (1), conical drum shell (2), polyurethane plastics rods tooth (3), spout (4), belt pulley (5),
Grain collector (6), motor (7) and core discharging outlet (8) are constituted, it is characterised in that: conical drum shell (2) internal production has spiral
Plate tooth (1) and polyurethane plastics rods tooth (3), the deformation that polyurethane plastics rods tooth (3) is impacted is more than rigid rod tooth,
Installing spiralling plate tooth on cylinder, plate tooth promotion corn ear is spinned while motion, is increased axial conveying capacity,
Also making Semen Maydis and conical outer wall be fully contacted increasing friction force, that can effectively protect that corn particle suffered after being clashed into is broken
Bad.
Described flexibility squeezes stranding formula corn thresher drum, and the material of threshing bar tooth is by common elastic modelling quantity rigid cylindrical
Bar, changes the flexible polyurethane plastic cylinder bar of elastic modelling quantity into；The external shell of cylinder is designed to pyramid type housing, be corn with
Cylinder, the frictional force of bar stripping fork brush are gradually increased vertically, it is ensured that through threshing；Spiralling plate tooth, plate are installed on cylinder
Tooth promotion corn ear is spinned while motion, and spiral lamina tooth applies a power in the axial direction to Semen Maydis, increases axially
Conveying capacity, also make Semen Maydis and conical outer wall be fully contacted increasing friction force.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model flexibility squeezes stranding formula corn thresher drum.
Fig. 2 is that this utility model flexibility squeezes stranding formula maize sheller overall structure schematic diagram.

In figure: 1, spiral lamina tooth, 2, conical drum shell, 3, polyurethane flexible bar tooth, 4, spout, 5, belt pulley, 6,
Grain collector, 7, motor, 8, core discharging outlet.
Detailed description of the invention
With reference to shown in Fig. 1, Fig. 2, Fig. 3, the flexible primary structure squeezing stranding formula corn thresher drum includes: corn ear
Feeding from spout (4), corn ear rotates with the spiral lamina tooth (1) on cylinder, the process moved axially forward
In curried and the extruding of conical drum shell (2) by polyurethane flexible bar tooth (3), realize de-under the effect of frictional force
Grain.The Semen Maydis fruit that threshing is got off is collected by grain collector (6), and corn cob is finally discharged from thresing machine rear end core discharging outlet (8).
Threshing course, based on threshing kinetics, is simplified to corn that quality is M with initial velocity V0 by this new design
Clash into, the threshing tooth of elastic cantilever, threshing tooth polyurethane flexible bar tooth (3) therefore can being fixed on cylinder can be reduced to
Equivalence regards cantilever beam as by the counter-force effect of grain and deform (such as accompanying drawing 3), under identical stroke speed, rods
The deformation deflection of tooth, the time contacted with corn is more than rigid rod tooth, in the case of drum rotation speed is certain, uses flexible threshing
Tooth, adds the time of contact with fruit grain, decreases impulsive force, it is possible to decrease seed is damaged.
Described flexibility is squeezed stranding formula corn thresher drum and be it is characterized in that: under identical drum rotation speed, plasticized polyurethane
Material rods tooth (3) deformation that is impacted is more than rigid rod tooth, and that can effectively protect that corn particle suffered after being clashed into is broken
Bad.Described flexibility squeezes stranding formula corn thresher drum, the material of threshing bar tooth by common elastic modelling quantity (E=200～
210GPa) bigger rigid cylindrical bar, changes the flexible polyurethane plastic cylinder that elastic modelling quantity (E=174～240MPa) is less into
Bar；The external shell of cylinder is designed to pyramid type housing, is corn and cylinder, and the frictional force of bar stripping fork brush the most gradually increases
Greatly, it is ensured that through threshing；Installing spiralling plate tooth on cylinder, plate tooth promotion corn ear is spinned while motion, spiral shell
Rotating plate tooth applies a power in the axial direction to Semen Maydis, increases axial conveying capacity, also makes Semen Maydis abundant with conical outer wall
Contact increasing friction force.
