Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Embodiment 1: extremely shown in Figure 5 as Fig. 1, the utility model discloses a kind of improved harvester header, by ceding of Taiwan casing 1, be fixed on first fixed mount 11 on the ceding of Taiwan casing 1, be installed in seedling-poking device 4 on first fixed mount 11, be installed in ceding of Taiwan casing 1 inside screw feeder, protect tooth and be installed in the scissors that protects in the tooth and form, first screw feeder 2 and second screw feeder 3 are installed in the ceding of Taiwan casing 1, between first screw feeder 2 and second screw feeder 3 dividing plate 12 is installed, uses in the dividing plate 12 and the junction of ceding of Taiwan casing 1 bottom surface HingeConnect, one hydraulic means 121 is installed on dividing plate 12, controlling dividing plate 12 by stretching of control hydraulic means 121 moves up and down, be equipped with first at the front end of dividing plate 12 and protect tooth 13, first protects tooth 13 moving up and down by dividing plate 12, adjust its height, make first to protect tooth 13 just below spike of rice, so that complete shears off spike of rice, be equipped with second at the front end of ceding of Taiwan casing 1 and protect tooth 14, first protects in the tooth 13 and second protects scissors 6 all is installed in the tooth 14, scissors 6 is by threaded first power transmission shaft 61 in surface and be a plurality of scissors rotating shafts 62 that vertical configuration installs with it and form, also there is the mutually meshing screw thread of screw thread with first power transmission shaft, 61 surfaces on the surface of scissors rotating shaft 62, for the screw thread on first power transmission shaft 61 and the scissors rotating shaft 62 particular requirement is arranged, first power transmission shaft 61 and screw thread on the scissors rotating shaft 62 wherein have a screw thread be tilt and another screw thread is vertical, could allow scissors rotating shaft 62 with its axle center rotation like this, one end of each scissors rotating shaft 62 is fixed with set of blades 621, the even number set of blades of each set of blades 621 and odd number set of blades not with the height, each even number set of blades is at sustained height simultaneously, each odd number set of blades is also at sustained height, be installed on each the scissors rotating shaft 62 on first scissors 6 that protects in the tooth 13 bearing 622 is installed, bearing 622 is fixed on the dividing plate 12, be installed on each the scissors rotating shaft 62 on second scissors 6 that protects in the tooth 14 bearing 622 is installed, bearing 622 is fixed on the base plate of ceding of Taiwan casing 1.Seedling-poking device is dialled paddy rice toward first direction of protecting tooth 13, second scissors 6 that protects in the tooth 14 is cut off the paddy rice stalk, seedling-poking device continues to rotate toward first direction of protecting tooth 13, when spike of rice partly arrives first when protecting tooth 13, first scissors 6 that protects in the tooth 13 is cut off spike of rice, first screw feeder 2 is transported to cut spike of rice on the conveyer belt of grain header, it is accurate that second screw feeder 3 makes rice straw enter the position of grass chopper 5 rotation of cut rice straw by second screw feeder 3, on the ceding of Taiwan casing 1 of second screw feeder, 3 belows grass chopper 5 is installed, grass chopper 5 is installed in the side that second screw feeder 3 goes out rice straw, grass chopper 5 is
