[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Through the design of the connecting components, quick assembly and disassembly are achieved through the cooperation of the locking block, tension spring, locking groove and connecting groove. When it is necessary to replace or install the threshing knife, the operator only needs to pull the locking block up and down to easily connect or separate the threshing knife from the connecting ring. This saves time in replacing the threshing knife, reduces labor intensity, and improves the versatility of the device, making it convenient to replace the appropriate threshing knife according to the threshing needs of different crops.

[0013] 2. Through the combined use of the pushing component and the connecting component, the cylindrical structure of the threshing knife and the pushing tooth cylinder increases the contact area between the threshing knife and the corn, making it easier for the corn kernels to separate from the corn kernels during rotation, greatly improving the threshing efficiency and reducing the time required for threshing. The electric telescopic rod ensures that the pushing tooth cylinder is always in close contact with the end of the corn kernels, ensuring that the corn kernels can continuously and evenly enter the working range of the threshing knife, avoiding the problem of incomplete threshing caused by corn accumulation or untimely pushing.

[0021] Please see Figures 1-4The feeding assembly 5 includes a guide groove 51 formed on the surface of the arc-shaped support plate 2. A connecting plate 52 is fixedly connected to the end of the arc-shaped support plate 2 away from the bearing 41. A feeding box 53 is fixedly connected to the top surface of the arc-shaped support plate 2. An electric telescopic rod 54 is fixedly connected to the end surface of the connecting plate 52 near the arc-shaped support plate 2. An arched groove 55 is formed on the side wall of the feeding box 53. A pull plate 56 is fixedly connected to the end surface of the electric telescopic rod 54 near the bearing 41. A storage bin 57 is provided inside the feeding box 53. The pull plate 56 is located near the bearing 41. One end surface of each of the plates 1 is rotatably connected to a pusher toothed cylinder 58, and the bottom surface of each pull plate 56 is fixedly connected to a limiting block 59. Each pull plate 56 is slidably connected to the inside of the guide groove 51 through the limiting block 59. Each driven gear 42 meshes with each other, and each drive gear 412 meshes with one of the driven gears 42. Each pull plate 56 is slidably connected to the inside of the arc-shaped support plate 2, and each pusher toothed cylinder 58 is slidably connected to the inside of the threshing knife 44. Each pull plate 56 slides in the guide groove 51 through the limiting block 59 to ensure the accurate movement trajectory of the pusher toothed cylinder 58.

[0022] Working principle: The corn to be threshed is placed sequentially inside the storage hopper 57. The corn at the bottom falls into the arc-shaped support plate 2, where it is positioned between the threshing blade 44 and the pushing toothed cylinder 58. The protective plate 49 is engaged with the top surface of the arc-shaped support plate 2, protecting the threshing blade 44 and preventing injury to the operator. The drive motor 411 is started, which drives multiple driven gears 42 to rotate via the drive gear 412. The driven gears 42 drive the connecting ring 43 to rotate via the bearing 41. 3. The threshing blade 44 rotates. Since the threshing blade 44 has a cylindrical structure and is positioned opposite to the pushing tooth cylinder 58, when the threshing blade 44 rotates, its cylindrical structure can thresh the corn located between the threshing blade 44 and the pushing tooth cylinder 58, separating the kernels from the corn kernels. At the same time as the threshing blade 44 rotates, the pushing assembly 5 starts to work. The electric telescopic rod 54 generates a thrust on the pull plate 56 towards the bearing 41. Under the action of this thrust, the pushing tooth cylinder 58 is pressed tightly against the end of the corn kernel. As the threshing blade 44 rotates, the pushing toothed cylinder 58 slowly pushes the corn towards the threshing blade 44. Through the threshing action of the threshing blade 44 and the pushing action of the pushing toothed cylinder 58, the separated kernels are discharged through the discharge pipe 3 fixedly connected to the bottom surface of the arc-shaped support plate 2 to the top of the guide plate 6, and are completely discharged from the top of the guide plate 6. Meanwhile, the corn stalks are pushed out through the hole in the center of the bearing 41 by the pushing toothed cylinder 58, completing the entire threshing process. When it is necessary to replace or install the threshing blade 44, the protective plate 49 is opened, and the operator... Pulling up the locking block 47 stretches the tension spring 48, disengaging the locking block 47 from the locking groove 45. At this point, align the connecting groove 46 on the surface of the threshing knife 44 with the locking groove 45 on the surface of the connecting ring 43, release the locking block 47, and under the elastic force of the tension spring 48, the locking block 47 slides into the locking groove 45, achieving a fixed connection between the threshing knife 44 and the connecting ring 43. Similarly, pulling up the locking block 47 disengages it from the locking groove 45, allowing the threshing knife 44 to be removed from the connecting ring 43, thus completing the disassembly of the threshing knife 44.
