Abstract
The utility model provides a threshing and separating mechanism of a corn harvester. The threshing and separating mechanism comprises a gland, a spindle, a bearing, a bearing seat, a feed inlet, an inner drum, an outer drum, a supporting rack and a flywheel. The spindle is fixed on the supporting rack through the bearing, the bearing seat for fixing the bearing, and the gland. The inner drum is mounted in the middle portion of the spindle, and the outer drum is mounted on the supporting rack at the outer side of the inner drum. The supporting rack is provided with the feed inlet which leads to the place between the inner drum and the outer drum. The flywheel is mounted at the lower end of the spindle. Rotating blades are mounted on the outer wall of the inner drum, and small projections are mounted on the inner wall of the outer drum. By employing the threshing and separating mechanism, small strips, blocks and chip mixtures generated after perforation of corn cobs are pushed by the rotating blades to move down and then are rubbed by the large number of small projections on the inner wall of the outer drum, so that corn kernels are separated thoroughly. The threshing and separating mechanism not only has high separation efficiency, but also causes no damage to the corn kernels.
Description
Technical field
The utility model belongs to agricultural mechanical field, is specifically related to a kind of corn picker threshing separating mechanism.
Background technology
At present, the corn threshing cut flow roller device for all feeding-in combine, adopts spike-tooth or drum with rasp bars to add the structure of notch board mostly, the sheller unit Threshing of this structure is poor, causes corn kernel broken serious, and grain loss is large, easily stop up cut flow roller, affect threshing speed.
Summary of the invention
For addressing the above problem, the utility model provides a kind of corn picker threshing separating mechanism, and little, fritter of corn ear after boring and broken last mixture, through this mechanism, are realized the separation of corn kernel.
The technical solution adopted in the utility model is: a kind of corn picker threshing separating mechanism, comprises gland, main shaft, bearing, bearing block, charging aperture, interior cylinder, outer cylinder, fixed mount and flywheel; Main shaft is fixed on fixed mount by bearing block, the gland of bearing and rigid bearing, and interior cylinder is installed at main shaft middle part, and outer cylinder is arranged on the fixed mount in interior cylinder outside, has charging aperture and lead between internal and external cylinder on fixed mount, and flywheel is equipped with in main shaft lower end.
On described interior cylinder outer wall, rotation blade is housed.
On described outer inner wall of rotary drum, small convex head is housed.
Employing the beneficial effects of the utility model are: little, fritter and the broken last mixture of corn ear after boring, at rotation blade, promote descending, on outer inner wall of rotary drum, have that a lot of small convex heads play mincing, rubbing effect, corn kernel is thoroughly separated, not only separative efficiency is high, and does not damage corn kernel.
Accompanying drawing explanation
Fig. 1 mechanism map of the present utility model.
Reference numeral: cylinder, the outer cylinder of 7-, 8-fixed mount, 9-flywheel in 1-gland, 2-main shaft, 3-bearing, 4-bearing block, 5-charging aperture, 6-.
Embodiment
A corn picker threshing separating mechanism, comprises gland 1, main shaft 2, bearing 3, bearing block 4, charging aperture 5, interior cylinder 6, outer cylinder 7, fixed mount 8 and flywheel 9 as shown in Figure 1.Main shaft 2 is fixed on fixed mount 8 by bearing block 4, the gland 1 of bearing 3 and rigid bearing, interior cylinder 6 is installed at main shaft 1 middle part, outer cylinder 7 is arranged on the fixed mount 8 in interior cylinder 6 outsides, has charging aperture 5 and lead between internal and external cylinder on fixed mount 8, and flywheel 9 is equipped with in main shaft 2 lower ends; On described interior cylinder outer wall, rotation blade is housed; On described outer cylinder 7 inwalls, small convex head is housed.
When mechanism works, little, fritter and the broken last mixture of corn ear after boring enters between internal and external cylinder from charging aperture, at rotation blade, promote descendingly, have that a lot of small convex heads play mincing, rubbing effect on outer inner wall of rotary drum, corn kernel is thoroughly separated.
