The elastic telescopic rod 45 has a thick part and a thin part slidably inserted in the thick part. The thin part is the telescopic end, and a spring is arranged inside the thick part to support the thin part, which can not only support the thin part, but also enable the thin part to shrink when compressed. The telescopic end of the elastic telescopic rod 45 passes through the side wall of the discharge hopper 8 and extends to the interior of the discharge hopper 8. The telescopic end of the elastic telescopic rod 45 is rotatably connected to a baffle 46 located on the inner side of the discharge hopper 8, and one end of the baffle 46 is rotatably connected to the inner wall of the discharge hopper 8.

[0035] When the present invention is used, the power machine 6 is started to drive the first rotating shaft 15 to rotate, and the connection shaft 20 is driven to rotate through the transmission of the first bevel gear 18 and the second bevel gear 19, thereby driving the first peeling roller 25 to rotate. The first bevel gear 24 is used to drive the first peeling roller 25 and the second peeling roller 26 to rotate in engagement with each other, and the fifth sprocket 27, the third chain 28, and the sixth sprocket 29 are used to drive the pulling roller 30 to rotate.

[0038] The corn cobs discharged through the discharge hopper 8 can be collected in the collecting bag 49, and there is no need to pick up the corn, which is conducive to the subsequent transfer or transportation of the corn. After one of the collecting bags 49 is filled with corn cobs, the hydraulic cylinder 41 is started to contract, driving the vertical plate 44 to move, and the elastic telescopic rod 45 can drive the baffle 46 to rotate and close, thereby blocking the discharge hopper 8, so that the discharge hopper 8 temporarily stops discharging materials, and then the vertical plate 44 continues to move. At this time, the elastic telescopic rod 45 can be retracted and will not hinder the continued movement of the vertical plate 44. When the rack 42 is engaged with the second bevel gear 43, it can drive the second bevel gear 43 to rotate 180 degrees, and the tray 47 is driven to rotate 180 degrees through the third rotating rod 51. Ten degrees, thereby completing the position exchange of the two collecting bags 49, and then the other unfull collecting bag 49 can be directly used to rotate to the bottom of the discharge hopper 8, waiting for the corn to continue to be collected, and then the hydraulic cylinder 41 is started to extend, and the vertical plate 44 is reset and moved. Since a one-way bearing is installed between the second bevel gear 43 and the third rotating rod 51, the second bevel gear 43 does not rotate at this time, and then the baffle 46 is driven to rotate and open through the elastic telescopic rod 45, and the corn on the inside of the frame 1 can be discharged through the discharge hopper 8 and continue to be collected. At this time, the staff can unload the full collecting bag 49 and reinstall another new collecting bag 49. In this process, there is no need to stop the corn harvesting process, thereby further improving the efficiency of corn harvesting.
