Component 86, the unloading component 86 includes a unloading plate 861 arranged below the connecting rod 82, and a unloading port 862 is connected to the center position of the bottom end of the unloading plate 861. When the screened wheat grains pass through the operation of the angle adjustment mechanism 6, they will fall on the supporting block 87, and then fall into the gap between the grinding block 85 and the grinding cylinder 81 below. At this time, the third motor 83 drives the gear block 84 to rotate, thereby driving the grinding block 85 to rotate, crushing the wheat grains between the grinding block 85 and the grinding cylinder 81, and then fall into the unloading plate 861 below and finally fall out from the unloading port 862.

[0031] The above embodiment discloses a wheat flour milling and screening machine, wherein, by adjusting the operation of the first motor 61, the threaded rod 62 is driven to rotate, thereby driving the movement of the adjustment block 64, and the adjustment rod 66 moves together while adjusting the angle between the screening shell 71 and the upper surface of the connecting seat 5, so as to achieve the purpose of tilting the screening shell 71, and the operation of the second motor 731 drives the wheel disc 732 to rotate. At this time, the connecting rod 733 starts to make a circular motion with the rotation of the wheel disc 732, thereby driving the control block 734 to slide back and forth up and down inside the limiting sleeve 735, so as to achieve the purpose of vibration. The impurities and poor-quality wheat grains after screening will fall into the blanking plate 7434. The staff can take out the blanking plate 7434 from the opening 7435 for cleaning. When the screened wheat grains pass through the operation of the angle adjustment mechanism 6, they will fall on the supporting block 87 and fall into the gap between the grinding block 85 and the grinding cylinder 81 below. At this time, the third motor 83 drives the gear block 84 to rotate, thereby driving the grinding block 85 to rotate, crushing the wheat grains between the grinding block 85 and the grinding cylinder 81, and then falling into the blanking plate 861 below and finally falling out from the blanking port 862.
