[0068] After the straw is harvested and collected in the loading trough, the inclined surface of the inclined plane block 10 approaches the lower side of the slope 1201 until the ball 1001 fits with the slope 1201; subsequently, the linear moving mechanism 6 drives the movable plate 8 and the harvesting knife to approach the crushing box 2, and the ball 1001 slides and moves on the slope 1201 to climb, and the inclined plane block 10, the harvesting knife plate 9, the movable plate 8, the linear moving mechanism 6 and the top plate 5 go up together until the inclined plane block 10 moves to the upper side of the slope 1201 and the joint with the side opening 206.

[0069] The above design is used to transport the harvested straw to the top opening of the crushing box 2, thereby realizing the lateral transportation and lifting of the straw.
