Description
Technical field
This utility model is related to harvester field and in particular to a kind of cleaning plant for corn mowing machine.
Background technology
With the raising of Agricultural Mechanization Degree, the Semen Tritici aestivi as staple crops and Oryza sativa L., mostly adopt combining
Machine gathers in, and substantially increases work efficiency, reduces the labor intensity of friend peasant.But, dress cleaned by present united reaper
The operation principle put is：Crop moves to making axle stream in united reaper sheller unit, and in this process, seed is taken off
Fall, stem and leaf deforms, de- seed and partial impurities and short stem and leaf under the action of the centrifugal force, fall distribution screw feeder, by distribution screw feeder
Throw on the shuttle board of cleaning plant, and delivered to hybrid for paddy compound on sorting screen surface by vibration before and after shuttle board, lead to
Cross the effect of vibration and the blower fan in front and back of sorting screen, partial impurities and short stem and leaf are removed, and clean crop kernel is sent into
Tanker.The united reaper using at present, sorting screen is easily blocked by the miscellaneous remaining grade of broken stipes in feeding cleaning room, causes wheat
Grain, grain can not fall from sorting screen, and it is poor to clean effect, corn can with broken stipes miscellaneous remaining discharge body from chaff discharging port, lead to greatly
What the wheat grain of amount, grain spread is all to cause substantial amounts of waste fullly.
Utility model content
This utility model is intended to provide the cleaning plant for corn mowing machine, cleans asking of effect difference to solve harvester
Topic.
For reaching above-mentioned purpose, basic technology scheme of the present utility model is as follows：For the cleaning plant of corn mowing machine,
Including the scourclean of air exhauster, feed mechanism and the equal opening of upper/lower terminal, the top of described scourclean is provided with collecting hood, collects
It is provided with dust gathering arrester, collecting hood and dust gathering arrester are the taper of top end opening, the cone angle of collecting hood is 100 °, dust gathering arrester outside cover
Cone angle is 60 °, and the top of dust gathering arrester is connected with air exhauster by exhaust column；Scourclean is internally connected with and separates cone, separates cone bag
Include upper cone and the lower cone that bottom links together, the side wall of scourclean has charging hole；Described feed mechanism includes feeding
Pipe, motor and feed cylinder, one end of feed pipe is connected with scourclean, and the other end of feed pipe is connected with feed cylinder, in feed pipe
It is provided with feeding rod, feeding rod is connected with the outfan of motor near one end of feed cylinder, in feed cylinder, be provided with feeding oar, feeding oar
It is connected by belt with the outfan of motor.
The principle of this programme and advantage are：Feed cylinder is connected with the sheller unit of harvester, the corn quilt after preliminary disengaging
Feed cylinder sent into by sheller unit, and motor by the feeding oar in belt drives feed cylinder, corn is sent in feed pipe, feeding
Corn is persistently sent into feed pipe until corn entrance scourclean by oar, and motor simultaneously drives the feeding rod in feed pipe to rotate and makes to send
Corn in expects pipe is not stopped transport dynamic, prevents corn from blocking in feed pipe.The top of scourclean connects air exhauster by exhaust column,
Air exhauster detaches the air in scourclean, forms negative pressure and the corn in feed pipe is sucked scourclean, through de- in scourclean
Carry out grain on the separation cone that the corn that the grain preliminary threshing of device is processed impinges upon in scourclean to separate with stem, after separating
Grain can be discharged by the bottom dropped out of scourclean due to heavier mass, and the negative pressure that the stem of lighter weight produces in air exhauster is made
With under be pulled out scourclean from exhaust column, the collecting hood that scourclean top arranges taper can prevent the grain in scourclean to be splashed to
Outside scourclean, 100 ° of cone angle makes the conical surface of collecting hood more gentle, and after grain strikes collecting hood, angle of rebound is little, is less susceptible to
Launch outside scourclean；The dust gathering arrester of taper is set outside collecting hood, and dust gathering arrester top connects exhaust column, and dust gathering arrester will be from cleaning
The stem discharged in cylinder collects guiding exhaust column, is discharged by exhaust column.This programme produces negative pressure by air exhauster and inhales corn
Enter scourclean high-speed impact to realize grain and separate with stem on separating cone, the difference using grain and stem weight realizes grain
With the sorting of stem, it is few that grain and stem mix situation, and grain wastes few, and detached stem is taken away at concentration by air exhauster
Reason, the pollution to environment is little.
Preferred version one, based on scheme a kind of improvement, the cone angle of described upper cone is 90 °, described lower cone
Cone angle is 60 °, aligns with the middle part of charging hole in the junction of upper cone and lower cone.So setting separates the upper/lower cone bored even
Meet place and form wedge, corn enters from feed pipe and impinges upon the preliminary disengaging carrying out grain and stem wedge after scourclean, 90 °
Cone angle make the conical surface of upper cone and clean barrel and keep certain angle there is larger area simultaneously, the paddy broken up by wedge
Grain in upper cone and is cleaned between barrel bounce-back and is cleaned threshing, cleans effect preferable；The lower cone of 60 ° of cone angles can carry for upper cone
For stable support, frequently impacted by corn during preventing the long-time use of upper cone and be deformed affecting cleaning efficiency.
Preferred version two, a kind of preferably one improvement, separating cone is hollow-core construction, separates top and the bottom of cone
End is equipped with via；The upper lateral of scourclean is equipped with peg, and the middle part of peg is vertically connected with suspension rod, and on suspension rod, screw thread connects
It is connected to locking nut, separate cone and be located between locking nut and peg.So setting makes to separate cone under the impact of corn
Can be rotated with suspension rod for axle, preventing separation from boring is that same position is subject to corn to clash into and be deformed all the time, hollow-core construction
Separation cone cost is lower, and locking nut respectively will be spacing to the top and bottom that separate cone with peg.
Preferred version three, preferably a kind of two improvement, passes through connecting tube between described feed pipe and scourclean
Connection, the two ends of connecting tube are separately fixed on feed pipe and the side wall of scourclean, and feed pipe is fixed near one end of scourclean
There is end cap.The size of so setting feed pipe discharging opening will not be constrained by feeding pipe diameter, the larger corn of facilitate volume
Group enters scourclean by feed pipe.
Preferred version four, a kind of preferably two improvement, described feeding rod rotates connection away from one end of motor
On end cap.So setting is all supported by the two ends that motor and end cap make feeding rod, and the rotation of feeding rod is more flat
Surely, feeding is more stable.
Preferred version five, preferably a kind of two improvement, described feeding rod is fixed with spiral helicine blade.If
Put blade the corn stem in feed pipe can be crushed in advance, make corn clean effect after entering scourclean more preferable；Spiral
Corn in feed pipe can also be continued feeding to scourclean by the blade of shape, and air exhauster, feeding rod and feeding oar all carry out feeding,
Mitigate the burden of feeding oar, make feed mechanism service life longer.
Preferred version six, a kind of preferably two improvement, the bottom outside of described scourclean is fixed with installing rack.
Setting installing rack is easy to fixing scourclean and is installed material placing device in the bottom of scourclean.
Preferred version seven, a kind of preferably two improvement, the bottom sidewall of described scourclean is drawn in center and is in
Shrink mouth shape.So setting makes the grain cleaned in scourclean after separating will not be scattering into four when scourclean lower ending opening drops
In week, all discharge from the middle part of scourclean after being constrained by necking.
