Abstract
The invention discloses a lower cutting knife straw stirring mechanism of a caterpillar harvester. The lower cutting knife straw stirring mechanism of the caterpillar harvester comprises a lower cutting knife arranged in front of a walking caterpillar track, wherein the lower cutting knife comprises a stationary knife rod and a movable knife rod; the head end of a straw stirring device is fixedly connected with the middle part of the movable knife rod through a connecting piece and is positioned above the movable knife rod; the straw stirring device reciprocates along with the movable knife rod, and the included angle alpha formed by a rod body and the movable knife rod is between 5 and 45 degrees; and sawteeth are uniformly distributed on the front edge of the straw stirring device. For the lower cutting knife straw stirring mechanism of the caterpillar harvester, the head end of the straw stirring device is fixedly connected with the middle part of the movable knife rod through the connecting piece and is positioned above the movable knife rod, and the straw stirring device reciprocates along with the movable knife rod, so that straw heads cut off from the middle parts by the lower cutting knife are continuously pushed to the end part by the sawteeth on the straw stirring device and fall off, and then the straw heads are ground by the walking caterpillar track and completely fall off to the ground from the lower cutting knife. The cutting knife straw stirring mechanism of the caterpillar harvester ensures that the straws cut off from the middle parts are transferred to the end part and fall over, so that the technical problem that grasses can be easily accumulated in the middle part of the lower cutting knife can is well solved.
Description
Technical field
The present invention relates to a kind of caterpillar band harvester, be specifically related to a kind of caterpillar band harvester lower cutter device.
Background technology
Existing caterpillar band harvester utilizes the upper cutter knife in the ceding of Taiwan that the grain ear of crops such as rice wheat is raised after point cuts off, and can stay higher surplus stubble, is contained in the following cutter of the reaping hook back lower place, can cut once more surplus stubble and reduce highly, cultivates to adapt to the follow-up of field.Following cutter is arranged on grain header traveling crawler the place ahead, distance between its width and the left and right sides crawler belt outside is unanimous on the whole, after the stalk that is partly cut off by the following two ends of cutter falls, the crawler belt that the stalk head can be walked later rolls throws oneself on the ground, thereby involving whole section stalk successfully falls from following cutter, therefore, long-pending careless phenomenon can not take place on the cutter down in the stalk that partly cuts off of two ends; But the stalk that cuts off between the crawler belt inboard, the left and right sides, promptly by the stalk that cuts off in the middle part of the following cutter, because of the stalk head that lodges can not be subjected to rolling of crawler belt, the influence that stalk is subjected to rice wheat stubble and is interweaved, be easy to stop and pull on following cutter and rear body, and constantly accumulation forms bigger long-pending careless group, and pushing the place ahead crops have a strong impact on the harvesting operation.
Summary of the invention
Defective at the prior art existence, the technical problem to be solved in the present invention is, cutter stalk poking mechanism under a kind of caterpillar band harvester is provided, it can push the stalk that descends the cutter middle part to cut off to end portion, make the stalk of lodging can be subjected to crawler belt and roll and throw oneself on the ground, avoid down the cutter middle part long-pending careless phenomenon to occur.
The technical solution used in the present invention is, cutter stalk poking mechanism under a kind of caterpillar band harvester, comprise the following cutter that is installed in traveling crawler the place ahead, following cutter comprises the moving knife bar of stationary knife bar and band cutting teeth, dial stalk device head end through connector fixedly connected moving knife bar middle part and be positioned at moving knife bar top, it is reciprocating to dial stalk device servo-actuated knife bar, and its body of rod and moving knife bar angle α are 5
o-45
o, dial the uniform sawtooth in stalk device forward position.
In the following cutter course of work, the stalk device servo-actuated knife bar of dialling that is fixedly connected on moving knife bar top constantly moves back and forth fast, by the stalk that cuts off in the middle part of the following cutter, in the lodging process, its stalk head is subjected to dialling the repeatedly propelling movement effect of stalk device sawtooth, can move to down the cutter end portion step by step, drop into down in the space between cutter and the traveling crawler, rolled by traveling crawler subsequently and throw oneself on the ground, roll the stalk head of throwing oneself on the ground and to involve whole section stalk and fully fall, thereby avoid down the cutter middle part careless phenomenon to occur amassing from following cutter.
The angle α that the above-mentioned group of stalk device body of rod become with the moving knife bar is 10
o-40
o, suitable angle setting can make angle tooth efficient when pushing the stalk head of dialling the stalk device higher, better effects if, and further optimizing angle is 15
o-35
o
Above-mentioned sawtooth be shaped as right angled triangle.Wherein a right-angle side is perpendicular to group stalk device body of rod and towards following cutter end portion.The sawtooth of right angled triangle can make sawtooth efficient when pushing the stalk head higher, is difficult for rewinding the stalk head during return motion, pushes better effects if.
The tail end of above-mentioned group of stalk device also is provided with to hold up and send handle, and holding up the angle that send handle and dial between the stalk device body of rod is 20
o-85
oHold up and send handle further to hold up and deliver to down the cutter end portion, successfully drop into traveling crawler the place ahead, reduce part stalk head still falls into the cutter central region dialling the tail end landing of stalk device phenomenon moving to the stalk head of dialling stalk device tail end.
Above-mentioned hold up send sawtooth is set on the handle, can improve to hold up and send holding up of bar to send effect.
The present invention will be by dialling stalk device head end through the fixedly connected moving knife bar of connector middle part and be positioned at moving knife bar top, and it is reciprocating to dial stalk device servo-actuated knife bar, the stalk head that cut off at the cutter middle part under the feasible quilt is constantly pushed to end portion by the sawtooth on group stalk device and falls, rolled by traveling crawler subsequently and fully come off and throw oneself on the ground from following cutter, the stalk that has cut off in the middle part of having realized is transferred to the end portion lodging, thus the fine easily long-pending careless technical problem in time cutter middle part that solved.
