Under the action of two spiral push plates 201, the straw is pushed to the middle of the feeding hopper. At the same time, the push plate 202 rotates with the spiral push plate 201, which facilitates the push of the straw in the feeding hopper to the feed inlet of the crushing mechanism body 1 for fine crushing.

[0031] Specifically, the baling mechanism includes a conveying component 3 for conveying the crushed straw into the baling bag 8 and a pressurizing component 5 for increasing the tightness of the straw in the baling bag 8. The conveying component 3 includes a collecting hopper 301 connected to the discharge port of the crushing mechanism body 1 and a conveying cylinder 302 fixed to the bottom of the collecting hopper 301. The collecting hopper 301 is fixed to the rear end of the crushing mechanism body 1 and is connected to the conveying cylinder 302. The end of the conveying cylinder 302 away from the collecting hopper 301 is extended and has an outlet for fitting the baling bag 8. A spiral auger 303 rotates inside the conveying cylinder 302. The side of the collecting hopper 301 near the crushing mechanism body 1 is connected to the discharge port of the crushing mechanism body 1.
