Embodiment 1
[0020] The auxiliary header device of the plot grain combine harvester includes a grain divider 10, a reel assembly 1, a side baffle 13, a cutting assembly 11, a conveying device, an auger, a toothed plate feeding roller 3 and a hydraulic motor. The grain divider 10 is arranged on both sides of the front end of the auxiliary header device. The cutting assembly 11 is located at the front bottom end of the auxiliary header device and is used for cutting straw. The conveying device is a striped belt conveying device 4, which is arranged behind the cutting assembly 11; The tooth plate type feeding roller 3 is installed at the rear end of the auxiliary header device, and its outer surface is arranged with 6 wavy tooth plates along the axial direction, the height of the tooth plates is 30-40mm, which is used to feed the harvested straw and ears without damage. into the threshing device. The side baffles 13 are fixed on both sides of the header device to prevent seed grains and ear...
Embodiment 2
[0023] Different from Embodiment 1, the fixed air chamber body 27 is composed of a hollow area 25 and a solid area 26, and the hollow area 25 is provided with an air inlet 24 connected with the header fan 14, and the air inlet 24 is connected with header fan 14 by airflow hose II8. Since the fixed air chamber body 27 is divided into a hollow area 25 and a solid area 26, during the relative rotation of the rotating air chamber cover 28 and the fixed air chamber body 27, the radial channel 23 passes through the hollow area 25 and the solid area 26 respectively. At 25 o'clock, the hollow reel 17 rotates to the lower half with the eccentric reel 19, and the longitudinal airflow blown out in this section of the stroke can cover the cutting table; when passing through the solid area 26, the hollow reel 17 rotates with the eccentric reel 19 For the first half of the way, above the cutting deck, there is no airflow and no auxiliary airflow required.
Embodiment 3
[0025]Different from Embodiment 2, the auxiliary header device also includes a lateral airflow chamber 3, which is connected to the header fan 14 through an airflow hose I6; the bottom side of the side baffle 13 is provided with Horizontal airflow hole 12, described horizontal airflow hole 12 is connected with horizontal airflow chamber 7; The airflow blown out by horizontal airflow hole 12 blows off the seeds on both sides of the header to the striped belt conveying device 4 in the middle section. The rotating air chamber cover 28 is provided with four radial passages 23 distributed along the circumference, and the radial passages 23 communicate with the split air passage 15 . The diameter of the reel 21 is 4mm, and the length is 20mm.
