[0022] In this embodiment, the shell 1 serves as the main structure of the thresher, and provides the functions of protecting internal components, supporting and fixing various components. The first motor 4 is connected to the transmission rod 3 through a reducer, providing a stable power source, ensuring that the transmission rod 3 can smoothly and evenly transport corn and reduce the breakage rate of corn cobs. The angle setting of the guide plate 5 helps the threshed corn kernels and corn cobs to slide smoothly along the guide plate 5, reducing the residence time in the shell 1. The dust removal component is used to separate light impurities generated during the threshing process, such as corn silk, dust, etc., to improve the purity of the discharged corn kernels. The screening component is used to screen the threshed corn kernels and remove the broken corn cobs.

[0023] In a further preferred embodiment of the utility model, the dust removal assembly includes multiple dust suction tubes 14, a limit box 15, a connecting pipe 16 and a fan 17, the multiple dust suction tubes 14 are fixed on the shell 1, the limit box 15 is fixed on the shell 1 and fixedly connected to the multiple dust suction tubes 14, the connecting pipe 16 is installed on the limit box 15, the fan 17 is fixed to the bottom of the shell 1, and the air inlet end of the fan 17 is fixedly connected to the connecting pipe 16.

[0024] In this embodiment, the dust suction pipe 14 can cover the key areas inside the thresher, ensuring that light impurities generated during the threshing process, such as corn silk, dust, etc., can be effectively sucked in. The limit box 15 collects and integrates the impurities sucked in by each dust suction pipe 14. The fan 17 provides a strong suction force, so that the light impurities generated during the threshing process can be smoothly sucked into the limit box 15.

[0025] In a further preferred embodiment of the utility model, the screening assembly includes a support ring 7, a plurality of springs 8, a collecting box 9 and a driving member, the support ring 7 is fixed in the shell 1, the plurality of springs 8 are fixedly mounted on the top of the support ring 7, the collecting box 9 is fixed on the top of the plurality of springs 8, a screen 10 is provided at the bottom of the collecting box 9, the driving member is arranged in the shell 1, and the outer wall of the collecting box 9 is in contact with the inner wall of the shell 1.

[0026] In this embodiment, the support ring 7 serves as the basic structure of the screening assembly and provides a stable support for the spring 8. The function of the spring 8 is to provide elastic support for the collecting box 9. This design allows the collecting box 9 to have a certain buffer space when it is vibrated or impacted. The collecting box 9 is the main part of the screening assembly. The corn kernels are screened on the screen 10, and the corn kernels and corn cobs are separated through the pores of the screen 10.
