Description
Technical field
The utility model relates to the grain harvest equipment into agricultural machinery, specifically a kind of millet harvester is used de-
Grain drum apparatus.
Background technique
Millet also cries grain, is grass family, broomcorn millet race, a cultivar of setaria (Setria itarlica bueav)
(2n=2x=18), English name foxtail millet, away from modern existing 7300 cultivation histories.It is generally called millet in northern China,
Claim millet after peeling.Fringe is tied after millet is mature, every solid number of fringe is up to 10,000 or so, real minimum, the diameter about 0.1cm of son, mass of 1000 kernel
3g or so, golden yellow after grain ear is general mature, oval seed.German millet nutrition value is very high, contains protein abundant and fat
And vitamin, it is one of the main food of the north of China people.
Millet harvester used in the prior art is not to gather in dedicated for millet, but by rape, rice, small
The harvester of the crops such as wheat carries out the harvesting that millet is used for after being simply transformed.Since millet is compared with the crops such as wheat, rice,
Its grain and chaff skin separating difficulty are larger, and the drum threshing equipment of conventional harvester is easy to break the crust of grain, thus
The quality of millet is caused to decline.
Utility model content
Grain is often resulted in order to solve existing other crop harvesters its threshing cylinder when being used as millet harvesting
The problem of crust breakage, the utility model provide a kind of millet harvester threshing cylinder, by by the threshing cylinder
The upper design of the barrel of device is equipped with the soft enclosed area of rubber spacer at inner wall, and on soft enclosed area inner wall
It is uniformly arranged the auxiliary separating mechanism made of rubber of special construction, so that grain ear be made to collide thereon by threshing axle impact
When, the crust that can considerably reduce grain is damaged.
Technical solutions adopted by the utility model to solve the above technical problems are as follows: a kind of disengaging rolling of millet harvester
Wound packages is set, which includes the internal barrel with threshing axle, the both ends of barrel be provided with feed inlet and
Discharge port, the lower part of barrel is mesh casing, so that the grain after threshing be made to drop into lower section after mesh casing is sieved
Stock guide on, the top of the barrel is the soft enclosed area that inner wall is equipped with rubber spacer, in soft enclosed area inner wall
On be evenly distributed with several auxiliary separating mechanisms, each auxiliary separating mechanism includes the rubber being fixed on rubber spacer
Pedestal is connected, is tiltedly installed with long rubber threshing board and short rubber threshing board, and long rubber respectively on the surface of rubber connection pedestal
Glue threshing board and short rubber threshing board form √ shape, the rotation side of the inclination extending direction and threshing axle of the long rubber threshing board
To intersection, so that threshing is completed on the surface that the grain ear for throwing away threshing axle impinges upon long rubber threshing board.
A kind of preferred embodiment of the utility model is that the lower part of the discharge port is provided with fixed baffle, fixed gear
Plate protrudes the bottom of discharge port, so that forming stalk at discharge port bottom accumulates area.
Another preferred embodiment of the utility model is that secondary sieve is additionally provided between the stock guide and mesh casing
Plate, and form short stalk between secondary sieve plate and mesh casing and blow channel.
Another preferred embodiment of the utility model is that the secondary sieve plate blows channel outlet close to short stalk
One end, which has, upwarps section.
Another preferred embodiment of the utility model is that the bottom of the fixed baffle passes through hinge and an active catch
Plate rotation connection, and when hinge is opened naturally, short stalk is blowed channel enclosed by flapper.
Another preferred embodiment of the utility model is that the threshing axle includes the electricity on barrel central axes
The shaft of machine driving, is arranged at intervals at least two round connecting plate, and two of them along its length in the shaft
Round connecting plate is in inside the both ends of barrel, is evenly arranged with several and barrel central axes around these round connecting plates
Parallel fixed link is evenly distributed with several bars of thrashing along its length in every fixed link, drives shaft by motor
With the rotation of fixed link, the bar of thrashing in fixed link is made to carry out beating threshing to grain ear.
In the utility model, the leading portion magnitude of inclination of the stock guide is greater than rear end magnitude of inclination, consequently facilitating grain exists
Movement on stock guide.
Compared with prior art, the utility model has the following beneficial effects:
1) it is more easier since millet (namely millet) crust after threshing is compared to for the crops such as wheat, rape
Breakage, and then nutritive value is caused to reduce, doping is more, and the top of barrel is arranged to inner wall and is laid with rubber by the utility model
The soft enclosed area of bed course reduces millet so that grain ear be enable to generate elastic buffer when impact is in soft enclosed area
Appearance breakage rate；Meanwhile in order to improve the threshing quality of millet, also for the buffering further enhanced when grain is hit, soft
Matter enclosed area setting auxiliary separating mechanism, auxiliary separating mechanism have long rubber threshing board and short rubber threshing board, grain ear with
Long rubber threshing board is struck in threshing axle rotation process first, is then collided with short rubber threshing board, in multiple collision
In the process, threshing efficiency is improved, and considerably reduces the breakage of grain crust；
2) in order to solve the problems, such as grain ear, millet cleannes are poor after threshing in threshing cylinder, percentage of impurity is high, this reality
Barrel is improved with novel, secondary sieve plate will be added again below the lower web shell of barrel, thus to cereal into
Row postsearch screening, improves cleannes, and compared with conventional harvester, threshing is very clean, there's almost no broken stalk
With the impurity such as blade；And form short stalk between secondary sieve plate and mesh casing and blow channel, the interior short stalk sifted out
In the case where the wind-force of the screening blower of body itself blows, channel is blowed along short stalk and is blown out, and since short stalk blows channel
End has flapper, so that it be made to be accumulated in channel end, and by manually being cleared up, prevents the short stalk of blowout
In cereal after dropping into cleaning again.
