In this embodiment, be provided with the cutting head that a plurality of symmetry set up on the cutting platform 5, the cutting head position is corresponding with the feed inlet of guide part 4 for the stalk stem can all effectively evenly cut off.

In this embodiment, two end side ends of the two material poking rods 701 are both disposed in an inward concave manner, and the two material poking rods 701 are respectively located above and below the material poking belt 614.

It should be noted that two extending ends of the two material stirring rods 701 exceed the material guiding curved rail 602 in the advancing direction of the self-propelled vehicle 1, so that the cut stem and ear can be smoothly turned over.

The working process and principle are as follows: when the broom sorghum harvester is used for harvesting, firstly, the initial height of the guide curved rail 602 is determined by adjusting the locking nuts on the upper side and the lower side of the guide curved rail 602 on the guide rod 619, so that the length of the stem ears to be harvested is determined, during the running process of the harvester, the driving motor 601 is started, the output end of the driving motor is driven to drive the belt wheel I606 to rotate through the rotating shaft 605, the driving belt 609, the belt wheel II 608 and the gear wheel I607 drive the gear wheel III 617 to rotate synchronously, the driving belt 614 is driven to rotate on the mounting disc 613 circularly through the gear wheel II 616, the broom sorghum between ridges enters the guide curved rail 602 through the guide gap in the middle of the guide curved rail 602 and is shifted into the self-moving vehicle 1 through the driving belt 614, during the process, the broom sorghum moves to the highest point of the guide curved rail 602 along a certain rising arc, the broom is cut off by the cutting knife I603, the required stem ears are cut off, and the stems at the lower end are discharged from the air feeder channel 8 through the cutting knife 19, when a short broom sorghum is encountered, the upper ear of grain is larger and can be clamped at the upper end of the middle gap of the guide curved rail 602, the guide curved rail 602 is pressed with the continuous advance of the harvester, the spring 620 is in a compressed state on the guide rod 619, the tooth socket 615 moves downwards relative to the gear II 616 and keeps meshed with the gear II, the gear III 617 also moves downwards relative to the gear I607 for the same distance and keeps meshed with the gear II, so that the cutting knife I603 is driven to rotate at a high speed and move downwards, and after another sorghum with a long height is continuously harvested, the heights of the guide curved rail 602 and the cutting knife I603 are restored again under the elastic action of the spring 620, so that the stems harvested below the ear of grain are kept consistent all the time;

for the cut stem ear, in the rotation state of the first gear 607, the second bevel gear 708, the first bevel gear 707 and the fourth gear 703 drive the two upper and lower material-shifting rods 701 to slide in the guide seat 612, since the fourth gear 703 is a notched gear with symmetrical teeth, and the tension spring 702 is elastically pulled by itself, the fourth gear 703 drives the two material-shifting rods 701 to synchronously and reversely extend and retract in the guide seat 612 in the rotation process, taking the extending state of the upper material-shifting rod 701 as an example (fig. 5), at this time, the lower material-shifting rod 701 extends to the left side and is located below the material-shifting belt 614, the stem will rotate around the material-shifting belt 614 in the left side after contacting the left material-shifting belt 614 in the process of entering the self-propelled vehicle 1, the head ear part faces the inside of the paper surface, the tail end of the stem extends to the outside of the paper surface, and the corresponding right material-shifting rod 701 will make the stem rotate around the material-shifting belt 614 in the opposite direction, so that the stems and ears fed onto the feeding plate 14 are in a mutually staggered and reversed stacking state and enter the threshing roller 16 for threshing under the inertia effect;

finally, after threshing by the threshing roller 16, the glumes screened by the screen 15 fall into the collecting groove 11 through the blanking cavity 17, and then are conveyed to the grain storage bin 2 through the secondary fine screen of the roller 12 and the conveying lifting cylinder 13 at the end part to finish the glumes harvesting, and the broom corn for manufacturing the broom or the cooking broom keeps a mutually staggered and reversely stacked state, and enters the collecting cavity at the rearmost end of the self-propelled vehicle 1 at the largest filling ratio.

Based on the above, the fixed-length cutting mechanism 6 is arranged on the self-propelled vehicle 1, plants move to the highest point of the guide curved rail 602 through a curved surface with a certain rising radian, and are cut by the first cutting knife 603 to complete the cutting of the required stem ears, when the broom sorghum with a short growth vigor is encountered, the seed ears at the upper end are clamped at the upper end of the middle gap of the guide curved rail 602 due to large individuals, and the guide curved rail 602 and the first cutting knife 603 synchronously lift along with the pressing effect of the harvester on the guide curved rail 602 along with the continuous advance of the harvester, so that the sorghum plants with different growth vigors and heights can be cut by the same length;

through setting up crisscross straw separating mechanism 7 that cooperates fixed length cutting mechanism 6, to the stem ear after cutting off at the in-process that gets into from carriage 1, the stem ear of both sides carries out the rotation of opposite direction to the stem ear of advancing on the feed table 14 is mutual dislocation and reverse pile up the state, can pile up whole storage cavity slowly after threshing, prevents to take place to lead to the phenomenon that storage area space utilization is low because of the stem ear of grain orientation one side.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
