The discharge port 21 is used to discharge the crushed straw. A discharge baffle 22 is installed on one side of the discharge box 20. The discharge baffle 22 can effectively reduce the splashing of the crushed straw during discharge, and prevent the crushed straw from flying into the eyes, nose and mouth of the staff.
[0022] Refer to Figure 1 , the top of the bucket 1 is connected to a harvesting support 2, and a harvesting roller frame 3 is provided at one end of the harvesting support 2. The harvesting support 2 is used to support the harvesting roller frame 3. A plurality of harvesting knives 4 are installed on one side of the harvesting roller frame 3. And a winding shaft 5 is arranged inside the bucket 1. The harvesting knives 4 wind up the straw and send it into the winding shaft 5. The winding shaft 5 is used to send the straw into the feeding pipeline 6. The feeding pipeline 6 is arranged on one side of the bucket 1. And a feeding shaft 7 is installed inside the feeding pipeline 6. A conveyor belt 8 is covered outside the feeding shaft 7. The conveyor belt 8 sends the straw along the feeding pipeline 6 into the grain separation box 9 by the rotation of the feeding shaft 7.
[0023] Refer to Figure 1 , Figure 4 and Figure 5 , the feeding pipeline 6 is connected to the grain separation box 9 on one side. And a first guiding plate 11 is arranged inside the grain separation box 9. The first guiding plate 11 is used to guide the straw sent by the conveyor belt 8 into the grain separation box 9.
