At the depth of, when the detection tube 7 is inserted, the inner tube is sealed at the detection port 11, so that the detection tube 7 is blocked from entering the detection tube 7 during the insertion of the detection tube 7 into the grain pile, avoiding damage to the temperature and humidity detector 10. After reaching the specified position, the electric telescopic rod 8 can be used to pull the inner tube 9 upward, so that the grain to be detected is placed inside the detection tube 7.

[0025] Reference Figure 1 A worm gear 4 is rotatably connected to the upper surface of the movable seat 2, a threaded through hole is provided at the central axis position of the worm gear 4, a thread is provided on the outer surface of the detection tube 7, and the detection tube 7 passes through the threaded through hole at the central axis of the worm gear 4, a limiting groove is provided on the side surface of the detection tube 7, a limiting strip is integrally connected to the inner wall of the guide tube 6, and the limiting strip is buckled in the inner part of the limiting groove, a first motor 3 is fixedly connected to the upper surface of the movable seat 2, a worm 5 is fixedly connected to one end of the rotating shaft of the first motor 3, and the worm 5 is meshingly connected with the worm gear 4, wherein when the detection tube 7 is inserted, the first motor 3 can be started, and the first motor 3 can be used to drive the worm 5 to rotate, because the worm 5 is meshingly connected with the worm wheel 4, the worm wheel 4 starts to rotate, and because the worm wheel 4 is threadedly connected to the detection tube 7, the detection tube 7 is limitedly slidably connected to the inside of the guide tube 6, so the rotation of the worm wheel 4 can effectively drive the detection tube 7 to move the axial position, ensuring that the detection tube 7 can be effectively inserted into or pulled out of the grain pile.

[0026] Reference Figure 2, a plurality of rollers 12 are rotatably connected on the symmetrical side surfaces of the movable seat 2, and the rollers 12 are located on the inner side of the track beam 1. A motor seat 15 is fixedly connected to the upper surface of the movable seat 2, and a second motor 16 is fixedly installed on the inner side of the motor seat 15, and a gear 14 is fixedly installed on one end of the rotating shaft of the second motor 16. A rack 13 is fixedly connected to the inner wall of the track beam 1, and the gear 14 is meshingly connected with the rack 13. When the detection mechanism is moved to a different detection point, the second motor 16 can be started, and the second motor 16 drives the gear 14 to rotate. Since the gear 14 is meshingly connected with the rack 13, the gear 14 can roll on the rack 13, thereby driving the movable seat 2 to slide on the inner side of the track beam 1, and the detection point can be effectively moved to the specified detection position.

[0027] Working principle: When in use, first install the device at the designated position. During the grain storage process, the device can be started intermittently and used to detect different positions of the grain pile. During detection, start the second motor 16, and the second motor 16 drives the gear 14 to rotate. Since the gear 14 is meshed with the rack 13, the gear 14 can roll on the rack 13, thereby driving the movable seat 2 to slide on the inner side of the track beam 1, which can effectively move the detection point to the designated detection position. Then start the first motor 3, and use the first motor 3 to drive the worm 5 to rotate. Since the worm 5 is meshed with the worm wheel 4, the worm wheel 4 starts to rotate. Since the worm wheel 4 is threadedly connected to the detection tube 7, the detection tube 7 is limitedly slidably connected to the inside of the guide tube 6, so the rotation of the worm wheel 4 can effectively drive the detection. The tube 7 moves axially to ensure that the detection tube 7 can be effectively inserted into the interior of the grain pile. When the detection tube 7 is inserted, the inner tube is sealed at the detection port 11, so that the grain is blocked from entering the detection tube 7 during the insertion of the detection tube 7 into the grain pile, thereby avoiding damage to the temperature and humidity detector 10. After reaching the specified position, the electric telescopic rod 8 can be used to pull the inner tube 9 upward, so that the grain to be detected is placed inside the detection tube 7. At this time, the temperature and humidity detector 10 can be used to perform temperature and humidity detection operations on the grain inside the grain pile.
