[0033] A feed pipe 17 extends from the back of the negative pressure fan 16, and a detection mechanism 19 is provided on the back of the two electric guide rails 1. A through hole is opened in the top center of the detection mechanism 19, and a collecting bucket 35 is arranged in the inner center of the detection mechanism 19.

Solenoid valves 27 are provided on the surfaces of the two detection feed pipes 26.

[0038] Furthermore, two guardrails 24 are fixedly installed with rolling door slide rails 34 on both sides of the grain discharge port 32, and the two rolling door slide rails 34 are slidably connected with a small rolling curtain 25, and a rolling curtain drive shaft housing 33 is arranged on the top of the two rolling door slide rails 34, and a rolling curtain drive shaft is arranged inside the rolling curtain drive shaft housing 33, and the rolling curtain drive shaft is rotatably connected with the small rolling curtain 25;

[0039] Specifically, when the grain is tested by the grain moisture detector 31, the information of the grain will be displayed on the display screen of the control device 20, and the staff will judge the quality of the grain according to the information on the display screen. When the quality of the grain meets the requirements, the small roller shutter 25 on the back of the opening of the detection mechanism 19 will be opened, so that the qualified grain will be discharged from the grain discharge port 32 on the back. The bottom of the detection mechanism 19 and both sides behind the second partition plate 22 are also provided with grain delivery ports. After entering the rear of the second partition plate 22, the grain will be output from the grain delivery port. The bottom of the grain delivery port is a grain warehouse, so that the grain with the required quality is transported to the grain warehouse. For the grain that does not meet the quality requirements, the small roller shutter 25 located in front of the guardrail 24 is opened, and the grain will flow out from the front grain discharge port 32, so that the grain with unqualified quality will be gathered at the opening of the detection mechanism 19. After the inspection of a truckload of grain is completed, the unqualified grain will be transported to the transport vehicle, so that the grain will be transported to a suitable place.

[0040] It should be noted that a partition plate is also provided at the inner center of the guardrail 24, the bottom of the partition plate is connected to the bottom of the detection mechanism 19, and the top of the partition plate is at the same horizontal plane as the top horizontal plane of the guardrail 24, thereby dividing the interior of the detection mechanism 19 into four parts through the first partition plate 21, the second partition plate 22, and the partition plate.

[0041] It should also be noted that a lifting block is provided at the inner top of the collecting barrel 35, and the top of the lifting block is at the same horizontal plane as the bottom of the detection feed port, so that after the height of the collecting barrel 35 reaches the requirement and the solenoid valve 27 is opened, all the grain inside the collecting barrel 35 can be transported to the two grain moisture detectors 31 for detection.

[0042] Furthermore, control devices 20 are fixedly connected to both sides of the detection mechanism 19;

[0043] Specifically, the two control devices 20 are electrically connected to the roller shutter drive motors on the outside of the two roller shutter transmission shaft housings 33 on the same side, and are also electrically connected to the rotary resistance material level switch 29, the solenoid valve 27, and the grain moisture detector 31 on the same side. It should be noted that the electrical connection between the control device 20 and the roller shutter drive motor, the rotary resistance material level switch 29, the solenoid valve 27, and the grain moisture detector 31 is the prior art, and its specific connection structure and circuit connection method will not be described in detail here.

[0044] In addition, the rotary level switch 29 is a prior art. When the grain level contacts the bottom of the rotary level switch 29, the control device 20 will start the solenoid valve 27, so that the grain will pass through the detection feed port 30 and the detection feed pipe 26 to the grain moisture detector 31 to detect the moisture of the grain. The data detected by the grain moisture detector 31 will be displayed on the display screen of the control device 20, and the staff will judge the quality of the grain.

[0045] It should be noted that how the rotary resistance level switch 29 activates the two solenoid valves 27 is also a prior art, and its specific connection structure and working principle will not be described in detail here.

[0046] Furthermore, a limit plate 18 is provided on the surface of the material conveying pipe 17 , and the limit plate 18 is fixedly installed on the top of the detection mechanism 19 .

[0047] Specifically, the feed pipe 17 in the present invention is a hose, wherein in order to fix the hose, a limit plate 18 is provided on the surface of the feed pipe 17, and the limit plate 18 is connected to the detection mechanism 19 by bolt fixing. When the sliding frame 5 moves, if the feed pipe 17 is not fixed, the feed pipe 17 may slide out of the through hole. It should be noted that the length of the feed pipe 17 is not Figure 1 The length shown in FIG. 1 shows that when the electric slide 2 moves to the electric guide rail 1 and is located at the farthest point of the detection mechanism 19, the feed pipe 17 will be straightened.

[0048] Furthermore, a driving motor 12 is fixedly mounted on one side of the sliding frame 5 , and an output end of the driving motor 12 is connected to one end of the lead screw 6 .

[0049] Specifically, the movable carriage 7 in the present invention can move along the inside of the sliding frame 5. When movement is required, the drive motor 12 is turned on. The rotation of the drive motor 12 will rotate the screw rod 6, and the rotation of the screw rod 6 will move the sliding frame 5, so that the sampling head 15 can be moved. By moving the sampling head 15, it is moved to the place where grains are gathered, so that sampling can be better performed, thereby improving the sampling efficiency.

[0050] Working principle: First, a transport vehicle filled with grain drives to the part between the two electric guide rails 1, and then the grain is sampled by the sampling device 15. During the sampling process, the grain will be sucked in from the sampling head 15 by the negative pressure fan 16, and then will pass through the sampling rod 14 to the negative pressure collection barrel inside the negative pressure fan 16. The negative pressure collection barrel is also connected to the feed pipe 17. Finally, the grain will enter the collection barrel 35 from the feed pipe 17 from the discharge port 23. When the height of the grain in the collection barrel 35 reaches the bottom of the rotary level switch 29, the solenoid valve 27 will be opened, so that the grain in the collection barrel 35 will be transported to the grain moisture detector 31 for detection. When the solenoid valve 27 is opened, the negative pressure fan 16 is in a closed state.

[0051] In addition, during the sampling process, in order to sample various parts of the grain in the conveyor vehicle, the sampling head 15 needs to be moved. When the sampling head 15 is moved horizontally, it is achieved by starting the drive motor 12. When the sampling head 15 needs to be moved longitudinally, it is achieved by starting the electric guide rail 1 to move the electric slider 2.

[0052] In addition, in order to better carry out sampling, it is sometimes necessary to insert the sampling head 15 into the interior of the grain, which can be achieved through the electric telescopic rod 10. Specifically, the electric telescopic rod 10 is started to extend and retract, and the movable plate 11 is lowered after extension and retraction. The descent of the movable plate 11 will cause the sampling head 15 to descend to the interior of the grain in the conveyor vehicle, thereby facilitating sampling of the interior of the grain.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
