[0028] In this embodiment, the diameter of the sealing gasket 4 is designed to be larger than the mounting seat 1, and the sealing gasket 4, the sealing pin 8 and the sealing block 505 are all rubber pads, so that the sealing gasket 4 will be in direct contact with the outer surface of the granary, and the mounting hole of the granary grain height measuring device will be sealed through the rubber pad.

[0029] In this embodiment, the bottom end of the cable lead 9 passes through the sealing tube 501, the sealing gasket 4, the mounting seat 1 and the connecting shaft 2 and the input end of the level meter head 3, the bottom end of the cable lead 9 is electrically connected to the inductive sensor 11, the top of the probe 12 is electrically connected to the inductive sensor 11, the sensor sleeve 10 is a stainless steel sleeve, and the sensor sleeve 10 extends into the interior of the granary.

[0030] In this embodiment, the sealing cylinder 501 is fixed inside the threaded groove 13 by means of threads, and four mounting grooves 502 are designed for mounting four sealing pins 8. The inner cavity 503 is opened on the rear side of the sealing pin 8, and the sealing block 505 is arc-shaped. The inner side of the sealing pin 8 is fitted with the inner wall of the mounting groove 502, and the upper end of the inner wall of the mounting groove 502 is an inclined surface, and the inner side of the sealing pin 8 is an inclined surface.

[0031] In this embodiment, the support rod 507 and the mounting groove 502 are designed to be parallel to each other, mainly to ensure that the sliding sleeve 508 will not encounter resistance when moving.

[0032] In this embodiment, the bottom end of the second electric push rod 512 is fixedly connected to the support plate 516, and the support plate 516 is pushed up and down by the second electric push rod 512. The movement will drive the sealing pin 8 to move upward.
