Abstract
The invention discloses a winnowing mechanism on a corn thresher. A threshing chamber is fixed on a frame, a threshing cylinder arranged in the threshing chamber is rotationally connected with the frame, a suction opening is arranged on the wall of the threshing chamber, a suction fan is arranged on the suction opening, and a grain retaining device is connected between the suction fan and the suction opening. The grain retaining device is composed of a shell and a plurality of retaining plates fixedly connected to the inner wall of the shell, the retaining plates are arrayed equidistantly in a manner of inclining to the top left, the upper end of each retaining plate bends towards the left bottom, and the lower end of each retaining plate bends to the top right. The upper end of each retaining plate bends towards the left bottom to be parallel to the ground, and the lower end of each retaining plate bends towards the top right to be parallel to the ground. The middle of each retaining plate inclines at 45 degrees or 135 degrees. The winnowing mechanism has the technical effect that corn grain can be blocked from being sucked away.
Description
Technical field
The present invention relates to maize sheller, particularly the pneumatic separator on maize sheller.
Background technology
Along with the universal of Tendency of Agricultural Machinery in China and high speed development.Corn threshing machinery is accepted by vast farmers.During the work of maize sheller; corncob is admitted to threshing chamber after sequentially passing through feeding unit, conveyer device; corncob is by after threshing chamber; corn kernel separates with corn cob; after air exhauster through being located on threshing chamber passes through the foreign material such as suction opeing sucking-off fine, soft fur thing, bracteal leaf of corn; corn kernel falls directly on the ground after being cleaned by the screen cloth of threshing chamber, corn cob is out fallen earthward by the knockout mouth on threshing chamber.But, while air exhauster sucking-off foreign material, also part corn kernel is followed foreign material sucking-off together and causes unnecessary waste, also affect yield.
Summary of the invention
It is an object of the invention to provide a kind of pneumatic separator that can stop on the maize sheller that corn kernel is sucked away.
The technical scheme is that and so complete; pneumatic separator on maize sheller; include threshing chamber, threshing cylinder, air exhauster, frame; threshing chamber is fixed in frame; the threshing cylinder being located in threshing chamber is connected with gantry rotation; threshing locular wall is provided with suction opeing, is provided with air exhauster at suction opeing, is connected and has seed retention device between air exhauster with suction opeing.
Further preferably embodiment, described seed retention device is made up of housing and several barrier plates being fixedly connected in inner walls, described barrier plate arranges in inclined upward shape the most to the left, and the lower section bending to the left of the upper end of barrier plate, the lower end of barrier plate is the most bent above.
Further preferably embodiment, parallel to the ground after the lower section bending to the left of the upper end of described barrier plate, the lower end of barrier plate is the most bent above rear parallel to the ground.
Further preferably embodiment, described barrier plate mid portion is 45 degree or 135 degree inclinations.
The solution have the advantages that, owing to having installed barrier plate between suction opeing and air exhauster additional, it is blocked, with corn kernel, the screen cloth that after plate stops, gap between barrier plate falls from threshing chamber to discharge, the foreign material such as fine, soft fur thing, bracteal leaf of corn are pumped by the gap between barrier plate, it is thus possible to effectively stop that corn kernel is pumped by air exhauster.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the A-A section structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation after barrier plate amplifies.
Detailed description of the invention
In conjunction with accompanying drawing, the present invention is described in further detail, threshing chamber is fixed in frame 4, and the threshing cylinder 3 being located in threshing chamber is rotationally connected with frame 4, and threshing locular wall is provided with suction opeing, being provided with air exhauster 1 at suction opeing, being connected between air exhauster 1 and suction opeing has seed retention device；Seed retention device is made up of housing 5 and several barrier plates 2 being welded on housing 5 inwall, and described barrier plate 2 arranges in inclined upward shape the most to the left, and the lower section bending to the left of the upper end of barrier plate 2, the bottom of barrier plate 2 is the most bent above.Flexibility α of barrier plate upper end is 160 degree.Flexibility β of barrier plate bottom is 160 degree.The lower section of barrier plate 2 is located at the suction opeing on threshing locular wall exactly.
For improving stop corn kernel effect, parallel to the ground after allowing the upper end of barrier plate 2 bend below to the left, the bottom of barrier plate 2 is the most bent above rear parallel to the ground.
For improving stop corn kernel effect, described cloudy baffle plate 2 mid portion is horizontal by 45 degree or 135 degree inclinations.Distance between barrier plate may be configured as 2-3 centimetre.
During work, corncob enters in threshing chamber from charging aperture, after threshing cylinder 3 threshing, the foreign material such as the fine, soft fur thing that separates from corn cob, bracteal leaf of corn are taken away by air exhauster 1 by suction opeing, are blocked being discharged by the screen cloth on threshing chamber in the corn kernel that plate 2 stops falls threshing chamber.
