Embodiment
Below in conjunction with the drawings and specific embodiments technical solution of the present invention being described in detail, further understanding purpose of the present invention, scheme and effect, but is not the restriction as claims protection domain of the present invention.
Corn kernel retracting device of the present invention is mainly used in corn combine or fixed corn husker, in use, it is installed in the below of the corn peeling device of above-mentioned corn combine or fixed corn husker.
Consult the front view of the corn kernel retracting device of Fig. 1 one embodiment of the invention, as shown in the figure, corn kernel retracting device of the present invention comprises frame 1, transmission device 2, separator 30 and seed case 4,
Wherein, transmission device 2 is arranged on the frame 1, and seed case 4 is arranged on separator 30 belows, and separator 30 comprises first separator 31 and bolter 32.
As shown in Figures 2 and 3, this first separator 31 is a disengaging latch, this disengaging latch is driven by transmission device 2, it comprises the chain 311 of two synchronous operations, 312 and be arranged on many cylinders 313 between two chains, many cylinders 313 are arranged on the whole chain length at interval and (only show part chain and part cylinder among Fig. 1 and Fig. 2), the two ends of every cylinder are riveted on the carrier bar 3111 of two chains by rivet 314, certainly, annexation between cylinder and the chain is not limited to riveted joint, also can adopt welding or other cylinder can be fixed in mode on the chain.Bolter 32 is arranged between the top and bottom of disengaging latch 31, promptly between the pilled-in selvedge and slack list of disengaging latch.Cylinder 313 herein is a round steel, and the spacing between many round steel is 15～25mm, and to constitute grid strip screen, the spacing that forms between per two round steel is defined herein as the grizzly bar hole.Bolter 32 is a steel wire, and the grid length of side of this steel wire is 10～30mm, is beneficial to the recovery of corn kernel.
In the present embodiment, the drive of transmission device 2 is a sprocket wheel.
The operation principle of this enforcement is: chain wheel drive disengaging latch 31 rotation counterclockwise, to drop on mixtures such as broken stipe on the disengaging latch pilled-in selvedge, maize leaves, made from bracteal leaf of corn, corn kernel under the apparatus for peeling off row, through the top of disengaging latch 31 from after, big impurity is because can not be by the grizzly bar hole on disengaging latch top, along with the rotation of disengaging latch 31 is delivered to front end row earthward; The less impurity of corn kernel and part passes the grizzly bar hole of disengaging latch 31 and falls on the steel wire 32, and through steel wire 32 secondary separations, bigger impurity is trapped on the wire rope net surface again, through the disengaging latch scraping delivery to steel wire front end row earthward; Pass the corn kernel of steel wire 32 and the grizzly bar hole that less impurity passes the bottom disengaging latch once more, fall into seed case 4, realize the recovery of corn kernel.The direction of motion of mixtures such as the broken stipe under the apparatus for peeling off row, maize leaves, made from bracteal leaf of corn, corn kernel is shown in the arrow among Fig. 1.
Consult the front view of the corn kernel retracting device of Fig. 4 another embodiment of the present invention; the difference of a present embodiment and a last embodiment is; first separator 31 is a crawler belt 31 '; be furnished with the upwardly extending strip hole 311 ' along crawler width side at interval on its length direction of crawler belt 31 ' upper edge, the pore size of those strip holes is 15～25mm.The drive of the transmission device 2 among this embodiment also is a sprocket wheel.
The operation principle of this enforcement is: chain wheel drive crawler belt 31 ' rotation counterclockwise, to drop on mixtures such as broken stipe on the crawler belt 31 ' pilled-in selvedge, maize leaves, made from bracteal leaf of corn, corn kernel under the apparatus for peeling off row, through the top of crawler belt from after, big impurity is because can not be by the strip hole 311 ' on the crawler belt 31 ', along with the rotation of minute crawler belt 31 ' is delivered to front end row earthward; The less impurity of corn kernel and part passes the strip hole 311 ' of crawler belt 31 ' and falls on the steel wire 32, and through steel wire 32 secondary separations, bigger impurity is trapped on the wire rope net surface again, through the crawler belt scraping delivery to steel wire front end row earthward; Pass the corn kernel of steel wire 32 and the strip hole that less impurity passes the bottom crawler belt once more, fall into the seed case, realize the recovery of corn kernel.
From top description as can be seen, corn kernel retracting device of the present invention has been installed steel wire in the middle of first separator, realized the secondary separation; And because must there be certain shake the slack list of this first separator in operation process, this shake is beneficial to corn kernel and passes disengaging latch/crawler belt, has improved separation rate, has reduced loss and percentage of impurity.
The corn combine of one embodiment of the invention except that the corn kernel retracting device adopt said structure unlike the prior art, remainder is same as the prior art, just seldom does at this and gives unnecessary details.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
