Abstract

The invention 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 holder and a flywheel. The spindle is fixed on the holder through the bearing, the bearing seat for fixing the bearing and the gland, the inner drum is mounted on the middle portion of the spindle, the outer drum is mounted on the holder on the outer side of the inner drum, the inner drum and the outer drum are communicated via the feed inlet formed in the holder, and the flywheel is mounted at the lower end of the spindle. Besides, 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. Strips, blocks and chip mixtures generated after the corns are perforated are rubbed by the small projections on the inner wall of the outer drum under driving of the rotating blades, so that corn kernels are separated completely. The threshing and separating mechanism has high separation efficiency without damages to corn kernels.

Description

A kind of corn picker threshing separating mechanism

Technical field

The invention belongs to agricultural mechanical field, be 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, adopt 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 invention provides a kind of corn picker threshing separating mechanism, little, fritter of corn ear after boring and broken last mixture, through this mechanism, are realized the separation of corn kernel.

The technical solution used in the present invention 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 the main shaft middle part, and outer cylinder is arranged on the fixed mount in the interior cylinder outside, has charging aperture on fixed mount and leads between internal and external cylinder, and flywheel is equipped with in the 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.

Adopt beneficial effect of the present invention to be: little, fritter and the broken last mixture of corn ear after boring, at rotation blade, promote descending, have on outer inner wall of rotary drum that a lot of small convex heads play mincing, the rubbing effect, corn kernel is thoroughly separated, not only separative efficiency is high, and does not damage corn kernel.

The accompanying drawing explanation

Fig. 1 mechanism map of the present invention.

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 kind of corn picker threshing separating mechanism, comprise 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 on fixed mount 8 and leads between internal and external cylinder, 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, promote descendingly at rotation blade, have on outer inner wall of rotary drum that a lot of small convex heads play mincing, the rubbing effect, corn kernel is thoroughly separated.
