[0023] like Figure 1 and Figure 2 The quick sampling device for stored rice shown in the figure comprises a middle circular shell 100, an upper fixing block 101 and a lower protective shell 109.
[0024] The upper fixing block 101 is provided with a shaft through hole 102 and a bearing mounting groove 103.
[0025] An upper fixing block through hole 112 is provided in the upper fixing block 101 and is located on one side of the shaft through hole 102 and the bearing mounting groove 103.
[0026] A bearing 104 is disposed in the bearing mounting groove 103.
[0027] The upper fixed block 101 is provided with a rotating shaft 105 through a bearing 104 and a rotating shaft through hole 102.
[0028] An upper fixing portion 106 and a lower fixing portion 107 are provided at both ends of the rotating shaft 105.

[0048] (4) The operator holds the middle circular shell 100 and rotates the hand wheel 108 counterclockwise to drive the rotating shaft 105 to drive the main driving gear 110 to rotate in conjunction with the hollow screw with internal thread groove 113, until the hollow screw with internal thread groove 113 drives the material taking screw 114, the material taking groove 118, and the material taking screw dividing teeth 117 to rise synchronously. When they rise to the corresponding position (the hollow screw with internal thread groove 113 and the plurality of conical dividing teeth 116 are located on the surface of the rice storage pile), the whole is moved away from the rice storage pile;
[0049] (5) The operator rotates one end of the material taking screw 114 clockwise through the anti-slip rotating part 115 to extend the hollow screw 113 with internal thread groove. At this time, the rice in the material taking trough 118 can be taken out for inspection (visual inspection / machine inspection).
