Description

Axial flow feeding rigid threshing and flexible separation combined roller assembly

Technical Field

The invention belongs to agricultural machinery, and mainly relates to a threshing roller for threshing operation in an axial flow feeding type threshing cylinder assembly.

Background

The axial flow feeding threshing cylinder is an assembly widely assembled and applied to combine harvesters for wheat and rice crops for threshing and separating in recent years. During operation, the operation assembly adopts a mode of feeding crop stalks into the threshing machine for threshing and separating, and because the quantity of the stalks is too large, more wheat grains or rice grains are removed and are easily carried in the threshed stalks to be discharged out of the threshing machine, so that grain loss is caused, and the grain recovery rate is low. For the above problems, due to the structural design deficiencies and defects of the conventional threshing roller, the separation and recovery operation of the grains which are carried in the stalks and are already threshed cannot be completed, and the structural design needs to be perfected and improved.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and researches and designs an axial flow feeding rigid threshing and flexible separation combined roller assembly with a novel structure by combining the actual requirements of the operation of an axial flow feeding type threshing cylinder, thereby achieving the purposes of reducing the entrainment loss of grains and improving the grain recovery rate.

The invention aims to realize that an axial flow feeding rigid threshing and flexible separation combined rolling shaft assembly comprises a main shaft, wherein an external screw feeding head, a front web plate and a rear web plate are fixedly arranged on the main shaft from front to back in sequence, a threshing rod seat is fixedly and uniformly distributed and supported on the position between the front web plate and the rear web plate along the circumferential direction, rigid threshing rods are fixedly arranged on the threshing rod seat, a shaking rod seat is uniformly and rotatably inserted on the rear part of the rear web plate along the circumferential direction, a wheel carrier and a sun gear are fixedly arranged on the main shaft at the rear end part of the rear web plate from front to back in sequence, the rear end part of the shaking rod seat is rotatably inserted on the wheel carrier, a planetary gear is fixedly arranged on the rear end of the shaking rod seat, the planetary gear is meshed with the sun gear, a fixedly arranged inner gear ring is sleeved on the outer part of the planetary gear and is meshed with each other, and a flexible shaking rod is fixedly arranged on the shaking rod seat between the rear spoke plate and the wheel frame from front to back in sequence.

The invention adds a flexible shaking rod which not only performs revolution motion but also performs rotation motion at the rear part of the stalk discharge end of the traditional threshing cylinder shaft, the rod can perform and complete elastic shaking on the threshed stalks before the threshed stalks are discharged out of the harvester, plays a role of loosening the stalks, separates and recovers part of grains clamped in the stalks, greatly reduces the grain clamping loss, and has the characteristics of unique and reasonable structure, high grain recovery rate and good use effect.

Description of part numbers in the figures:

1. the threshing device comprises an inner gear ring, 2, a sun gear, 3, a planetary gear, 4, a flexible shaking rod, 5, a threshing rod seat, 6, a front web plate, 7, an external spiral feeding head, 8, a main shaft, 9, a rigid threshing rod, 10, a rear web plate, 11, a shaking rod seat, 12 and a wheel carrier.

Detailed Description

The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. The utility model provides an axial-flow feeding rigidity is threshed and flexible separation combination roller bearing assembly, includes main shaft 8 adorn external screw feeding head 7, preceding radials 6 and back radials 10 in proper order on the main shaft 8 from the past after to in proper order on the position between preceding radials 6 and back radials 10 are relative along the circumferencial direction equipartition support dress threshing rod seat 5 admittedly, rigidity threshing rod 9 admittedly on threshing rod seat 5 follow the circumferencial direction equipartition on the back radials 10 rear portion and rotationally cartridge shake rod seat 11 main shaft 8 is located the back tip position of back radials 10 from the past after to in proper order admittedly dress wheel carrier 12 and sun gear 2, the rear end of shake rod seat 11 rotationally inserts on wheel carrier 12 firm planetary gear 3 on the 11 rear end of shake rod seat, planetary gear 3 meshes with sun gear 2 mutually, and the suit of the ring gear 1 of fixed motionless configuration is on planetary gear 3 outside, and the flexible shaking rod 4 is fixedly arranged on the shaking rod seat 11 between the rear spoke plate 10 and the wheel carrier 12 from front to back in sequence.

During operation, the external power transmission synchronously drives the external screw feeding head 7, the front web plate 6, the rear web plate 10, the wheel carrier 12 and the sun gear 2 to rotate through the main shaft 8, the rotating front and

rear web plates

6 and 10 drive the rigid threshing rod 9 to rotate through the threshing rod seat 5, the rotating rear web plate 10 and the wheel carrier 12 are matched to drive the flexible shaking rod 4 to revolve around the main shaft 8 through the shaking rod seat 4, in synchronization with the rotation, under the matching control of the rotating sun gear 2 and the fixed inner gear ring 1, the flexible shaking rod 4 rotates around the shaking rod seat 11 through the planet gear 3 and the shaking rod seat 11, at the moment, the stalks to be threshed fed from the external screw feeding head 7 are firstly threshed through the rigid threshing rod 9 in the flowing from front to back, then the stalks with part of threshed grains are clamped to enter the range of the shaking rod seat 11, under the action of the flexible shaking rod 4 in revolution and rotation, the stalks are disturbed, shaken and loosened to separate the entrained seeds from the stalk pile, and finally the stalks are discharged out of the machine from the discharge end of the roller assembly.
