The fixed bar 21 is fixedly connected to the housing 11, and a first slide groove 211 is provided on the fixed bar 21. The inner wall of the first slide groove 211 is slidably connected to the first slider 23. One side of the first slider 23 is fixedly connected to one end of the movable rod 22, and a first guide bar 221 is provided on the top of the movable rod 22. Figure 4 A limiting groove can be provided on the inner wall of the first slide groove 211, and a limiting protrusion can be provided on the first slider 23 corresponding to the limiting groove to prevent the first slider 23 from being separated from the first slide groove 211, thereby improving the stability of the first slider 23 when sliding. The top of the movable rod 22 is preferably set to a pointed shape to prevent wheat or debris from falling on the top of the movable rod 22.

[0033] During assembly, the fixing strip 21 may be cut transversely, and then the first sliding block 23 may be placed into the first sliding groove 211 , and then the fixing strip 21 may be welded and assembled together.

The two groups of sorting components 2 are arranged vertically, and the spacing between the movable rods 22 in the sorting component 2 located above is greater than the size of wheat. Wheat can pass through the spacing between the movable rods 22 to intercept larger debris, such as wheat straw fragments. The spacing between the movable rods 22 in the sorting component 2 located below is less than the size of wheat. Wheat is intercepted on the movable rods 22, while smaller debris passes through the spacing between the movable rods 22. It is preferred to set a discharge port at the bottom of the housing 11 to discharge smaller debris, such as wheat straw fragments or gravel and soil. The spacing between the movable rods 22 in the sorting component 2 located below can be adjusted according to the size of wheat, so as to facilitate the sorting of wheat, without the need to replace the screen, and the use is more convenient.

[0057] Then the motor 31 is driven to rotate, and the motor 31 drives the first connecting rod 32 to rotate. The rotating shaft 33 of the first connecting rod 32 makes a circular motion around the axis of the motor 31, and the rotating shaft 33 drives the second connecting rod 34 to rotate. The second connecting rod 34 drives the driving shaft 35 to rotate. The driving shaft 35 can drive the threshing drum 13 to rotate, and the threshing drum 13 drives the spiral pattern 131 to rotate, and the wheat ears are rubbed and threshed by rubbing with the inner wall of the casing 11.

[0058] When the rotating shaft 33 makes a circular motion, it drives the piston rod 37 to make a reciprocating linear motion through the third connecting rod 36. When the piston rod 37 drives the third piston head 38 to slide downward on the inner wall of the cylinder 39, the air inside the cylinder 39 is compressed, and the air enters the first accommodating chamber 2812 through the intake pipe 280. Under the action of air pressure, the first piston head 284 is pushed to slide on the inner wall of the first accommodating chamber 2812.

[0059] When the first piston head 284 slides, the third magnet 2521 is driven to slide on the upper surface of the fixed cylinder 281 through the action of the magnetic field. The third magnet 2521 drives the shielding plate 252 to slide to the side close to the guide block 2815. At this time, the wheat and debris fall on the shielding plate 252. At this time, the third piston head 38 continues to slide downward on the inner wall of the cylinder 39 until the first piston head 284 moves to Fig.11 On the left side of the second through hole 2821, the air inside the first accommodating chamber 2812 enters the second accommodating chamber 2813 through the second through hole 2821, and enters the third accommodating chamber 2814 through the third through hole 2831. Under the action of air pressure, the second piston head 286 overcomes the pulling force of the coil spring 289 and slides on the inner wall of the third accommodating chamber 2814. When the second piston head 286 slides, it drives the second magnet 287 to slide. Under the action of the magnetic field, the second magnet 287 drives the fourth magnet 2711 to slide on the lower surface of the fixed cylinder 281. The fourth magnet 2711 drives the scraper 271 to move. When the scraper 271 slides, it can drive the second The slider 272, the fixed shell 273, the spring 274 and the movable shell 275 move and slide to the side away from the guide block 2815, pushing the wheat or debris between the adjacent movable rods 22 to the position of the discharge port 111, and discharging the debris or wheat through the discharge port 111. The guide plate 112 can guide the debris or wheat discharged from the discharge port 111. At this time, the wheat and debris fall above the baffle plate 252, preventing the debris or wheat from falling on the left side of the scraper bar 271, which can ensure that the wheat and debris are cleaned up, and avoid debris or wheat remaining inside the thresher, which will cause interference and errors when threshing wheat from different breeding fields.

[0060] When the third piston head 38 slides upward, the air pressure inside the cylinder 39 decreases, and the air inside the fixed cylinder 281 is extracted through the air inlet pipe 280. When the air pressure in the third accommodating chamber 2814 is less than the tension of the coil spring 289, the second piston head 286 is automatically pulled to the upper side of the cylinder 39 by the tension of the coil spring 289. Fig.11 The scraper strip 271 also moves to the side close to the guide block 2815 to complete the reset. Then the third piston head 38 continues to slide upward, the air pressure inside the fixed cylinder 281 continues to decrease, and the first piston head 284 moves to Fig.11 On the right side of the middle, at this time, the first piston head 284 drives the third magnet 2521 to slide on the upper surface of the fixed cylinder 281 through the action of the magnetic field, and the third magnet 2521 drives the shielding plate 252 to slide to the side away from the guide block 2815, referring to Figure 6 The shielding plate 252 slides out of the discharge port 111, and the discharge port 111 will scrape the wheat and debris on the shielding plate 252 and drop them between the movable rods 22 under the shielding plate 252, completing the reset of the scraper bar 271 and the shielding plate 252.

[0061] The motor 31 rotates continuously, which drives the threshing drum 13 to rotate continuously. The threshing drum 13 drives the spiral pattern 131 to rotate, and the wheat ears are rubbed and threshed by rubbing with the inner wall of the casing 11. The motor 31 drives the scraping bars 271 on the two groups of sorting components 2 to move, and the wheat or debris on the movable rod 22 is automatically cleaned. The baffle plate 252 moves to the top of the movable rod 22 during the movement of the scraping bar 271 to prevent debris or wheat from falling on the left side of the scraping bar 271, thereby ensuring that the wheat and debris are cleaned and debris or wheat is prevented from remaining inside the thresher.
