Description
Technical field
The present invention relates to agricultural machinery technological field, automatically protect wheat grain header in particular to one.
Background technology
Grain header is the machinery of integration harvesting crops, disposablely completes harvesting, threshing, and grain is focused on repository, also can use hand harvest, the straw of the crops such as paddy and wheat is laid in field, and then carry out picking up threshing with cereal harvesting machinery.
Existing automatic protection wheat grain header directly carries out threshing to it when can not complete the harvesting of wheat, causes production efficiency low.Existing grain header straw after shearing through the wheat still needs manually to cut simultaneously, and manual labor can be caused like this to increase, and production efficiency reduces.
Summary of the invention
The object of the present invention is to provide a kind of wheat of protection automatically grain header, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is:
A kind of wheat of protection automatically grain header, comprise vehicle frame, it is characterized in that, described vehicle frame is provided with driver's cabin, sheller unit and reaping apparatus, and its lower end is provided with road wheel; Described reaping apparatus comprises harvesting mouth, and harvesting mouth is provided with harvesting cutter and motor, and the connecting axle of harvesting cutter is provided with torque sensor, is provided with safeguard structure between described harvesting cutter and motor; Described safeguard structure comprises housing, and shell one end is fixedly connected with mounting cover, and other end inwall arranges tapering along its axial direction, is provided with tapered pole in housing, and the tapering of tapered pole outer wall matches with the tapering of inner walls; Be provided with spring in described housing, spring one end is connected with tapered pole, and the other end is connected with mounting cover; Electromagnetic component is configured with between described mounting cover and tapered pole; Described motor output shaft stretches in housing, and through tapered pole; The connecting axle of described harvesting cutter is connected with mounting cover; Described harvesting mouth lower end is provided with rotating cylinder, and rotating cylinder is provided with from top to bottom and organizes cutter more, and the length of cutter reduces successively; Described sheller unit comprises threshing housing, is provided with cylinder in threshing housing, cylinder divides and is evenly covered with threshing projection; Described threshing housing lower end is provided with multiple through hole, and through hole lower end is provided with deposits wheat case; Described threshing housing communicates with harvesting mouth.
Further, multiple through holes of described threshing housing lower end are uniformly distributed.
Further, described electromagnetic component comprises electromagnet, controller and iron block, and electromagnet is arranged on mounting cover, and iron block is arranged on position corresponding with electromagnet on tapered pole, and electromagnet is connected with controller by circuit.
Further, described tapered pole is elastomeric material.
Further, described housing and mounting cover are bolted to connection.
The invention has the beneficial effects as follows,
One, cut wheat by harvesting cutter, make the straw on wheat top enter in sheller unit, cylinder rotates and makes threshing projection carry out threshing to it, and wheat is entered by the through hole on threshing housing to be deposited in wheat case; Harvesting cutter makes rotating cylinder rotate in harvesting simultaneously, cutter on rotating cylinder cuts off harvested straw, organize cutter, and the length of cutter reduces successively because rotating cylinder is provided with from top to bottom more, straw one section one section is cut off, is conducive to straw fast rotting.This grain header can be increased work efficiency, and reduces manual labor.
Two, the thrust produced by Compress Spring promotes tapered pole, tapered pole coordinates with housing taper face, make tapered pole to motor output shaft compression fit, realize motor output shaft and rotate drive housing into rotation, housing drives mounting cover to rotate, mounting cover drives the connecting axle of harvesting cutter to rotate, thus realizes cutting wheat.When too much straw is wound around blade, torque sensor sends a signal to controller, controller closing electromagnets circuit, electromagnet is made to produce magnetic, iron block moves tapered pole by attraction influence zone and overcomes spring thrust and move down, and make tapered pole not at clamping motor output shaft, motor output shaft and blade connecting axle are in off-state, thus effectively avoid motor stuck, cause motor damage.
Accompanying drawing explanation
Fig. 1 is the structural representation of automatic protection wheat grain header provided by the invention;
Fig. 2 is the structural representation of safeguard structure.
