[0027] The conveying mechanism includes a support base 6, on which multiple spiral rods 9 are rotatably connected via bearings. Multiple bearing seats 11 are fixedly mounted on the support base 6, and each bearing seat 11 is rotatably connected to a spiral rod 9 via a bearing. The spiral rods 9 are arranged in parallel and are connected to each other via a transmission connection. One spiral rod 9 is connected to a servo motor 10. Specifically, the servo motor 10 is fixedly mounted on the support base 6, and the output shaft of the servo motor 10 is connected to one end of the spiral rod 9 via a coupling. The top of the support base 6 is covered with a cover plate 7. The cover plate 7 and the support base 6 are fixed together by bolts. Specifically, a first mating block 61 is welded to the outer wall of the support base 6, and a second mating block 71 is welded to the outer wall of the cover plate 7. The first mating block 61 and the second mating block 71 are fixed together by bolts. A through hole 72 is provided on the cover plate 7. The cutting table auger pusher 3 pushes the crop to be cut into the through hole 72. The crop enters the inner cavity of the support base 6 through the through hole 72. An arc-shaped baffle 8 is welded on the cover plate 7. The end of the blade of the auger rod 9 is ground into a blade shape, so that the auger rod 9 can cut the crop.
