The bottom ends of the first threshing ring cutter 20 and the second threshing ring cutter 21 are respectively fixed to the top ends of two connecting rods 32. The radial cross-sectional shape of the first threshing ring cutter 20 is semi-circular, and the radial cross-sectional shape of the second threshing ring cutter 21 is a curve with gradually increasing curvature at both ends of the semi-circle. The top ends of the first threshing ring cutter 20 and the second threshing ring cutter 21 are provided with cutting edges that spiral upwards. Textured bar blocks 56 are arranged on the outer walls of the first threshing ring cutter 20 and the second threshing ring cutter 21. The fixing plate 25 is fixed to the frame 1.

Two vibrators 43 are fixed on both sides of the center of the screen plate 44 respectively.

[0019] During operation, when threshing corn, the corn is fed into the feeding cylinder 2. The third controller 55 drives the fan 52 to rotate forward via the sixth motor 54, thereby providing suction to the hose 18 with suction cups. The camera 9 observes the state of the corn after it falls out of the feeding cylinder 2 and wirelessly feeds the observed image back to the first controller 14. The first controller 14 controls the speed of the seventh motor 12, thereby controlling the output pressure of the hydraulic pump 13, and then controlling the extension and bending of the hydraulic pipe 16. It also adjusts the posture and position of the suction cups at the end of the hose 18 with suction cups, ensuring that the corn is vertically positioned at the center below the threshing drum 23. The first motor 5 drives the grooved cam 4 to rotate, causing the pointed follower 10 to slide on its... The cam slides within the groove. When the grooved cam 4 reaches its resting stage and contacts the pointed follower 10, the pointed follower 10 extends and pierces the center of the vertical corn, reinforcing the corn's posture control. The fifth motor 50 drives the disc cam 47 to rotate, causing the roller follower 51 to reciprocate up and down, which in turn drives the other diameter-changing devices (except for the slide rail 30) to reciprocate up and down, thereby driving the threshing ring knife to reciprocate up and down. During this time, the fourth motor 41 drives the diameter-changing shaft 38 to rotate, causing the diameter-changing block 39 to rotate, thus rotating the threshing ring knife. The camera 9 observes the diameter of the corn and wirelessly feeds the observed image back to the second controller 33. When the corn diameter is large, the second controller 33 controls the third motor 35 to rotate forward, causing the shaft to rotate. The sleeve 37 descends, pushing the variable diameter block 39 downwards along the chute, increasing the distance between the two threshing ring blades. When the corn diameter is small, the second controller 33 controls the third motor 35 to reverse, causing the sleeve 37 to rise. The variable diameter block 39 is reset by the second spring 40, thus reducing the distance between the two threshing ring blades. This allows the two threshing ring blades to spirally rise and fall while automatically adjusting according to the corn diameter, ensuring that the threshing ring blades accurately cut the connection between the kernel and the cob during ring cutting. When threshing rice or wheat, the rice or wheat is fed in through the feeding port 8. The third controller 55 controls the fan 52 to reverse through the sixth motor 54, thus providing blowing force to the hose 18 with suction cups. The position of the suction cups is observed through the camera 9. Similarly, the... The hydraulic system controls three hoses 18 with suction cups at their ends, which are located between the threshing drum 23 and the threshing ring knife and are distributed at equal circumferential angles. The second motor 28 drives the second gear 27 to rotate, which in turn drives the first gear 26 to rotate, thereby driving the threshing drum 23 to rotate. The threshing drum 23 drives the elastic threshing teeth 22 to rotate. The rotating elastic threshing teeth 22 cooperate with the stationary truncated bar block 56 to complete the threshing. Thus, automatic and uniform feeding of wheat or rice and low-loss buffered threshing are achieved. After the material is threshed, the vibrator 43 drives the screen plate 44 to move. Due to the position restriction of the support rod 45 by the hollow tube 58, the screen plate 44 vibrates back and forth, screening the mixture of grains and impurities that fall onto the screen surface.

One end of the first spring (11) is fixed on the pointed follower (10), and the other end is fixed on the limiting rod (57). The fan includes a fan (52) and a third controller (55). The fan is provided with a protective cover, which is fixed to the bottom of the outer wall of the feeding cylinder (2). The fan (52) is rotatably installed in the protective cover. The output end of the sixth motor (54) is fixed to the shaft of the fan (52). The third controller (55) is fixed on the sixth motor (54). One end of the third controller (55) is connected to the eighth battery (53), and the other end is connected to the sixth motor (54). The eighth battery (53) is connected to the sixth motor (54). The third controller (55) is connected to the eighth battery (53) and the sixth motor (54). The controller (55) controls the forward and reverse rotation of the fan (52); the feeding pipe includes a feeding port (8), a hose (19) and a hose (18) with a suction cup. The three feeding ports (8) are fixedly mounted on the three inner walls of the frame (1). The ends of the three hoses (18) with suction cups are fixedly mounted to the protective cover of the fan (52) and their interiors are connected to the airflow channel of the fan (52). One end of the three hoses (19) is connected to the three feeding ports (8) respectively, and the other end is connected to the three hoses (18) with suction cups respectively; the hydraulic system includes a hydraulic pipe (16), a hydraulic pump (13), a bend (17) and a first controller (14). The lower part of the hydraulic pipe (16) is provided with pipes of variable length and angle. The hydraulic pipe (16) is fixed to one end of the suction cup. Each suction cup is symmetrically fixed with two hydraulic pipes (16) on the top and bottom. The other end of the hydraulic pipe (16) is connected to one end of the bend (17). The other end of the bend (17) is fixed to the output end of the hydraulic pump (13). The output end of the seventh motor (12) is fixed to the input end of the hydraulic pump (13). The first controller (14) can wirelessly receive signals. The first controller (14) is fixed on the frame (1). One end of the first controller (14) is connected to the third battery (15), and the other end is connected to the seventh motor (12). The third battery (15) is connected to the seventh motor (12). The camera (9) is fixed to the bottom of the outer wall of the feeding cylinder (2). The camera (9) is connected to the second battery (7).
