[0039] A feed port is provided on the threshing component 12, and a mesh cylinder 13 is coaxially provided inside the threshing component 12. A threshing roller 14 is rotatably provided inside the threshing component 12, and the threshing roller 14 is driven to rotate by a power mechanism on the threshing component 12. An opening structure is provided near the feed port of the mesh cylinder 13, so that wheat can contact the threshing roller 14 after being fed into the mesh cylinder 13, and the wheat grains can fall into the screening component 11 through the mesh opening of the mesh cylinder 13.

[0040] Among them, the chip outlet 2 is opened on the side of the threshing component 12, and the waste wheat straw after threshing is discharged through the chip outlet 2. During implementation, since the structures of the screening component 11 and the threshing component 12 are existing mature technologies for technical personnel in this field, they will not be described in detail here.

[0041] Specifically, the re-screening assembly 3 is arranged outside the chip outlet 2, and the threshed waste wheat stalks are discharged from the chip outlet 2 and fall into the re-screening assembly 3, so that the waste wheat stalks are quickly screened for the second time, and the threshing efficiency is reduced. The collecting assembly 4 is arranged below the re-screening assembly 3, so that the wheat grains recovered for the second time are collected and collected by the collecting assembly 4;

[0042] For further information, please refer to Figure 1 and Figure 2 The re-screening assembly 3 includes a material receiving frame 5, a guide assembly 6 and a drive assembly 7. The outer side of the material receiving frame 5 is fixed to the guide assembly 6, so that under the guidance of the guide assembly 6, the activity trajectory of the material receiving frame 5 can be limited to reciprocating motion in the front and rear straight directions. The drive assembly 7 is arranged above the material receiving frame 5.

[0049] Among them, the output member 72 includes a synchronous roller 721 and a driving roller 722. One end of the synchronous roller 721 is coaxially fixed with the threshing roller 14, so that when the threshing roller 14 runs and rotates, it can drive the synchronous roller 721 to rotate synchronously. The driving roller 722 is fixed on the outer side of the synchronous roller 721. After the driving roller 722 moves into the strip groove 712, it applies force to the strip groove 712 through the buffer pad 713, so that when the driving roller 722 rotates clockwise, the driving roller 722 applies force to the inner wall of the strip groove 712, so that the frame 51 moves as a whole, and after the driving roller 722 rotates out of the strip groove 712, the frame 51 can be reset by the spring 632, and so on and so forth, so that the frame 51 can reciprocate to screen the waste stems therein and speed up the separation and screening of the wheat grains.

[0050] For further information, please refer to Figure 5 The collecting component 4 includes a collecting frame 41 and a discharging bin 42. The collecting frame 41 is arranged below the frame body 51, and the projection directly below the frame body 51 falls on the upper surface area of ​​the collecting frame 41, so that the collecting frame 41 can stably and effectively receive the wheat grains falling from the frame body 51. The discharging bin 42 is fixedly arranged at the bottom of the collecting frame 41, and the outer side of the discharging bin 42 is fixedly connected to the threshing component 12, so that the wheat grains are discharged from the bottom of the discharging bin 42 to facilitate the collection of materials.

[0051] During implementation, a slope 43 is provided on the bottom surface of the collecting frame 41 to facilitate the wheat grains to slide along the slope 43 into the discharge bin 42, thereby improving the discharge convenience.

[0052] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
