Description

Harvester header screw feeder feeding device

Technical Field

The invention relates to the technical field of agricultural harvesters, in particular to a harvester cutting table auger feeding device.

Background

The combine harvester has long continuous working time in a harvesting season, the header is easy to break down, and the auger shaft is frequently detached for maintenance when the header breaks down. The screw feeder structure that the harvester header that present manufacturer produced used is integrative member structure, including screw feeder axle and its outer screw feeder section of thick bamboo that cup joints, a plurality of helical blade of screw feeder section of thick bamboo external fixation, when screw feeder section of thick bamboo has the problem, the curb plate of both sides need to be pulled down, dismantle screw feeder axle and screw feeder section of thick bamboo wholly, it is very inconvenient to make taking out of screw feeder section of thick bamboo, it is inefficient to dismantle, and, when blade on the screw feeder section of thick bamboo appears the damage and causes the damage of screw feeder part, need more renew screw feeder section of thick bamboo during the maintenance, peasant's cost of maintaining or maintaining agricultural machinery has been increased.

The reasonable arrangement of the auger structure, the cutter and the reel on the cutting table is very important, and especially the distance between the center of the auger structure and the cutter at the front end of the cutting table has great influence on the working performance of the cutting table. If the distance from the center of the auger structure to the front end of the header is larger, the auger structure is more suitable for harvesting long-stalk crops. When the short-stalk crops are harvested, the crops are only firstly stacked between the cutting knife and the center of the screw conveyor structure, and when the crops are stacked to a certain amount, the crops are grabbed by the helical blades, and are jammed, so that the transportation blockage is easily caused. On the contrary, if the distance from the center of the auger structure to the front end of the header is smaller, the harvesting machine is more suitable for harvesting short stalk crops, and when long stalk crops are harvested, the long stalk crops are easy to slip off from the header, so that ear loss is caused.

Moreover, when the harvester meets different land sizes or the land sizes are changed, due to the fact that the size of the header of the harvester is fixed, if the width size of the header is large, harvesting operation is difficult to conduct on the land with small size, and if the width size of the header is small, the area of crops harvested in one trip in the land is small for the land with large size, and harvesting efficiency is reduced.

The header 1 meets under the not crop condition of co-altitude at the in-process of operation, compares the height signal transmission between reference bar 9 and the crop of waiting to cut for PLC through image processing module, and PLC judges the back-and-forth movement of screw feeder section of thick bamboo body 2. When judging that crops height is too high, can make auger barrel body 2 after motor II 41 drives, prevent that high-stalk crops from falling from header 1, causing the results loss. When judging that the crops height is too short, can prevent that crops from piling up in header 1 front portion with the 2 antedisplacement of an auger section of thick bamboo body, causing the jam, simultaneously, retractable's sectional type blade 14 can further cooperate, prevents the jam of an auger section of thick bamboo structure. The auger barrel body 2 drives the air blowing barrel 16 of the sliding table 432 in the process of moving back and forth, grains scattered in the header 1 are blown into the middle conveying belt 5, the conveying belt 5 rotates under the action of the motor II 41 and the gear mechanism II 6, and the grains scattered on the header 1 are smoothly fed into a device behind the harvester.

When the segmented blades 14 need to be repaired, each blade can be detached individually and the corresponding blade can be repaired. When other parts of the auger cylinder need to be maintained like an internal structure, the motor II 41 drives the reciprocating driving mechanism 4 to move, the auger cylinder body 2 is translated to the front of the whole cutting table 1, so that maintenance personnel can conveniently take out the auger cylinder from the front, and in the process of forward movement of the auger, the sliding table 432 touches the stop lever to extrude the stop lever, so that the supporting plate 81 transversely moves, and the auger cylinder connecting section 22 smoothly enters the upper part of the supporting plate 81 and completes stop positioning. Then, the motor i 31 rotates reversely, the screw sleeve 33 cannot rotate due to the locking of the ratchet mechanism 32, the reverse rotation of the motor i 31 is converted into the linear movement of the screw sleeve 33 on the output shaft of the motor i 31 by the screw thread in the screw sleeve 33, so that the support cylinder 23 connected with the screw sleeve 33 is driven to move towards the outer end of the auger cylinder body 2, the support cylinder 23 is separated from the auger cylinder main body 21, and the auger cylinder main body 21 or the auger cylinder connecting section 22 is detached as required.

When installing the screw feeder cylinder body 2 that will maintain after repairing back to header 1, cup joint screw feeder cylinder main part 21 and the screw feeder cylinder linkage segment 22 at both ends on supporting section of thick bamboo 23 and dock the back, rotate the bar key on the screw thread section of thick bamboo and dial the draw-in groove of putting the alignment card strip 72 bottom, get rid of the screw, card strip 72 makes card strip 72 die the screw thread section of thick bamboo card because gravity moves down, operation motor I31 makes its corotation this moment, and the screw thread section of thick bamboo is died by the card, the corotation of motor I31 converts into the linear motion that the screw thread section of thick bamboo was done along the direction of the output axial screw feeder cylinder main part 21 of motor I31, can accomplish the installation of screw feeder cylinder body 2. And finally, under the action of the motor II 41, the reciprocating driving mechanism 4 drives the auger cylinder body 2 to move and return.

While the foregoing is directed to the principles of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
