A matching movable hole 62 is opened at the lower end of the movable connecting plate 6, and a supporting limit rod 28 is plugged into the matching movable hole 62. Connecting support plates 63 are symmetrically fixedly provided on both sides of the lower end of the movable connecting plate 6, and connecting bearing plates 64 are symmetrically fixedly provided on the upper and lower sides of the connecting support plate 63. A connecting plug block 65 is fixedly provided on the connecting bearing plate 64, and the connecting plug block 65 is plugged into the connecting inclined groove 45, and the connecting plug block 65 contacts the inner side wall of the connecting inclined groove 45.

[0040] The conical block 7 is inserted into the feed pipe 11, and the two sides of the conical block 7 are symmetrically fixed with matching connecting rods 71, which are inserted into the connecting jack 13, and the upper end of the matching connecting rod 71 is fixed with an external connecting bearing plate 72, and a guide through hole 73 is opened on the external connecting bearing plate 72, and a guide vertical rod 14 is inserted in the guide through hole 73, and a second connecting spring 74 is sleeved on the guide vertical rod 14, and the two ends of the second connecting spring 74 are respectively fixed on the moisture meter 1 and the external connecting spring 74. A drooping bearing plate 75 is fixedly provided on the externally connected bearing plate 72, and a sloped driving frame 76 is fixedly provided on the lower end of the drooping bearing plate 75. In addition, the maximum diameter of the conical block 7 is smaller than the inner diameter of the feed pipe 11, and when the conical block 7 blocks the feed pipe 11, it is partially inserted in the sloped ring plate 12. In addition, the second connecting spring 74 can support the weight of the wheat added to the feed pipe 11, so that the conical block 7 can keep the feed pipe 11 in a closed state.

[0041] When testing the moisture content of wheat, the wheat is added to the feed pipe 11, and then the electric telescopic rod 18 is started to drive the movable bearing sleeve 2 to move, and the infrared detector 3 is also driven to move, so that the infrared detector 3 moves to the top of the feed pipe 11. In this process, as the movable bearing sleeve 2 moves, the driving inclined plane frame 292 will push the matching column 51 downward, and then drive the driving connecting bar 5 to move downward. As the driving connecting bar 5 moves downward, the connecting sliding sleeve 49 will also be driven to move downward. In this way, under the action of the connecting hinge rod 46, the two supporting movable plates 4 will be driven to move back to each other, so that the lower port of the movable bearing sleeve 2 is opened, which is convenient for the infrared detector 3 to detect the wheat, and the infrared detector 3 can The moisture content is calibrated according to the national standard method to ensure the accuracy of moisture detection. In addition, as the supporting movable plate 4 moves, the supporting bar 44 will also be driven to move. Under the action of the connecting inclined groove 45, the connecting plug block 65 will be driven to move, and then the movable connecting plate 6 will be driven to move in the direction of the infrared detector 3, so that the plug-in support rod 61 is plugged into the bearing socket 32.

That is, the installation and disassembly of the infrared detector 3 is very convenient. It only needs to be placed in the movable bearing sleeve 2. When the infrared detector 3 fails, it is also convenient to install and disassemble it for maintenance. The movable bearing sleeve When moving toward the feeding pipe 11, the hinged rotating plate 27 will contact the inclined driving frame 76, so that under the restriction of the inclined driving frame 76, the hinged rotating plate 27 will rotate counterclockwise, so that the hinged rotating plate 27 can smoothly pass over the inclined driving frame 76, and then maintain the vertical state again under the action of gravity. When the infrared detector 3 completes the wheat detection, the electric telescopic rod 18 is started to drive the movable bearing sleeve 2 to move in the reverse direction. During the reverse movement, the lower end of the hinged rotating plate 27 will contact the inclined surface part of the inclined driving frame 76, and due to the restriction of the inner wall of the hinge groove 26, the hinged rotating plate 27 cannot rotate clockwise, so under the action of the hinged rotating plate 27, the inclined driving frame 76 will be pushed to move downward. As the inclined driving frame 76 moves downward, the conical blocking block 7 will also be driven to move downward, so that the conical blocking block 7 will no longer block the inclined ring plate 12, so that the wheat can fall into the moisture meter 1 under the action of gravity to detect the moisture. When the movable bearing sleeve 2 moves in the opposite direction and passes over the inclined driving frame 76, the conical blocking block 7 will move upward under the action of the second connecting spring 74, so that the conical blocking block 7 blocks the feed pipe 11. At the same time, as the movable bearing sleeve 2 is reset, the driving connecting bar 5 will be moved upward and reset under the action of the first connecting spring 54, thereby driving the connecting sliding sleeve 49 to reset, so that the supporting movable plate 4 is closed again to support the infrared detector 3.At the same time, the support rod 61 is inserted and withdrawn from the bearing socket 32.
