The second threshing rack 12 is rotatably connected to the left part of the threshing box 2. A transmission assembly 11 is connected between the second threshing rack 12 and the first threshing rack 10. The third threshing rack 14 is rotatably connected to the lower left part of the threshing box 2. A gear set 13 is connected between the third threshing rack 14 and the second threshing rack 12. The transmission assembly 11 includes a belt and belt pulleys. A belt pulley is provided at the front part of the first threshing rack 10. A belt pulley is also provided at the front part of the second threshing rack 12. A belt is wound around the belt pulleys. The second support frame 15 is connected to the upper left part of the threshing box 2. The scraper 16 is slidably connected to the lower part of the second support frame 15.

[0021] When using the utility model, first place the first support frame 1 in the threshing area of the sunflower, and then pour the sunflower to be threshed into the threshing box 2 from the feeding port 3, so that the sunflower falls onto the placing rack 5 on the threshing box 2. Under the action of the gravity of the sunflower, the placing rack 5 rotates downward, so that the sliding rod 7 slides downward on the sleeve 6. After the first telescopic spring 8 is compressed and then rebounds, the placing rack 5 vibrates up and down, so that the sunflower slides to the left from the placing rack 5. When the sunflower passes through the first threshing rack 10, start the motor 9 to make the first threshing rack 10 rotate to perform the first round of threshing treatment on the sunflower. Then the sunflower continues to slide downward.

Under the extrusion of the second threshing rack 12 and the third threshing rack 14, the second round of threshing of the sunflower is carried out. Then the sunflower continues to slide downward. At the same time, when the second threshing rack 12 rotates, the rotating rack 18 rotates. Through the extrusion cooperation between the rotating rack 18 and the wedge block 17, the wedge block 17 moves back and forth. Under the action of the second telescopic spring 19, the scraper 16 slides back and forth on the second support frame 15 to perform the third round of threshing on the sunflower. The threshed sunflower seeds fall and are collected from the first discharge port 20, and the remaining sunflowers are discharged from the second discharge port 21, thus playing a role in being able to continuously thresh the sunflower multiple times, ensuring that the particles on the sunflower are completely removed, and reducing the waste of sunflower particles.
