[0027] In one embodiment, the bottom of the timing relay 16 is mounted on the top of the bottom plate 15, and one side of the control panel 17 is mounted on one side of the grain conveying pipe 30. The control panel 17 controls the stepping motor 11 to drive the turntable 12 to rotate, so that the turntable 12 drives the sample tray 13 to rotate, thereby enabling the differentiation of samples taken at different times, ensuring the accuracy of later detection results, reducing the workload of the staff, and improving work efficiency. Through the setting of the timing relay 16, the start and stop of the stepping motor 11 and the cylinder 25 can be controlled according to a predetermined time sequence to achieve sequential control, thereby enabling timed sampling. When random sampling is required, the stepping motor 11 and the cylinder 25 can be individually controlled through the control panel 17, thereby enabling random sampling.

[0028] In one embodiment, the sampling assembly 201 includes a through groove 20, a sampling spoon 21, a sampling groove 22, a tube body 23, a fixing plate 24, a cylinder 25, and a second support rod 26; the through groove 20 is opened at the bottom of the grain conveying pipe 30, the outer side wall of the sampling spoon 21 is slidably connected to the inside of the through groove 20, the sampling groove 22 is opened on one side of the sampling spoon 21, one end of the tube body 23 communicates with the inside of the sampling spoon 21, one end of the tube body 23 penetrates through the inside of the plate body 10, the outer side wall of the tube body 23 is slidably connected to the inside of the plate body 10, one side of the fixing plate 24 is fixedly connected to one side of the sampling spoon 21, the outer side wall of the cylinder 25 is fixedly connected to the top of the plate body 10, the piston rod of the cylinder 25 is fixedly connected to the bottom of the fixing plate 24, the bottom of the second support rod 26 is fixedly connected to the top of the plate body 10, and the top of the second support rod 26 is fixedly connected to the bottom of the grain conveying pipe 30. The control panel 17 controls the cylinder 25 to drive the sampling spoon 21 to move into the grain conveying pipe 30. Through the setting of the sampling groove 22, the grain in the grain conveying pipe 30 can enter the sampling spoon 21 through the sampling groove 22, and then be conveyed to the sample tray 13 through the tube body 23, thereby enabling rapid sampling of the grain and improving work efficiency.

[0029] In one embodiment, a feeding port 31 is installed at one end of the grain conveying pipe 30, and a discharging port 32 is installed at the other end of the grain conveying pipe 30.
