[0045] Embodiment 2: please refer to Figures 1 to 3 , 5-10, the embodiment provides a mobile coal moisture tester, which comprises all the structures in embodiment 1, and further comprises a protection assembly, which is sleeved outside the steel probe 8; the protection assembly comprises two symmetrical protective sleeves 14, which can be spliced together, and an insertion cavity 15 is formed inside the two protective sleeves 14 after splicing, a plurality of conductive columns 16 are arranged in each of the two protective sleeves 14, all the conductive columns 16 are uniformly distributed along the extension direction of the protective sleeve 14 on the corresponding protective sleeve 14, and the specific number of the conductive columns 16 can be selected and customized according to actual conditions; one end of each of the conductive columns 16 extends outward from the outer wall of the corresponding protective sleeve 14, and the other end extends into the insertion cavity 15 and abuts against the side wall of the steel probe 8 inserted into the insertion cavity 15.

[0046] In this embodiment, the outer wall of the steel probe 8 is provided with a limiting block 17 in an annular structure, the inner wall of the two side protective sleeves 14 is provided with a limiting groove 18 corresponding to the limiting block 17, the limiting block 17 is inserted into the limiting groove 18 when the two side protective sleeves 14 are spliced together, the top of the two side protective sleeves 14 is provided with a threaded connection hole 19, and the two threaded connection holes 19 are coaxially arranged and screwed with a connecting screw 20 after the two side protective sleeves 14 are spliced together. Through the foregoing arrangement, when the two side protective sleeves 14 are spliced, the limiting block 17 is inserted into the limiting groove 18 to limit the movement of the two side protective sleeves 14 along the length direction of the steel probe 8, and the connecting screw 20 is screwed into the two threaded connection holes 19 to connect the two side protective sleeves 14 together to limit the up-down movement of the two side protective sleeves 14 on the steel probe 8, so that the protective sleeve 14 is well connected to the steel probe 8 and is not easy to fall off.

[0047] In order to ensure the normal use of the tester, the connection between the steel probe 8, the protective sleeve 14 and the outer shell 1 needs to be further strengthened to prevent the steel probe 8 and the protective sleeve 14 from falling off. Therefore, the outer shell 1 is further provided with a limiting assembly, which includes a limiting cylinder 26 fixedly arranged at the connecting position of the steel probe 8 and the connecting port 7, and a rubber sleeve 27 in a circular column structure fixedly arranged on the inner wall of the limiting cylinder 26. The steel probe 8 passes through the inner ring of the rubber sleeve 27, and the inner wall of the rubber sleeve 27 is tightly arranged with the outer wall of the steel probe 8. Through the foregoing arrangement, the inner wall of the rubber sleeve 27 is tightly arranged with the outer wall of the steel probe 8, so that the rubber sleeve 27 can fix the steel probe 8 by its friction force, thereby connecting the steel probe 8 and the limiting cylinder 26 together, and further strengthening the connection between the steel probe 8 and the outer shell 1.

[0049] Since the protective sleeve 14 may generate static electricity when the outer side contacts the coal and the inner side contacts the steel probe 8 during use, the static electricity may affect the detection result of the humidity sensor 2, resulting in inaccurate result; based on this, on the basis of embodiment 2, embodiment 3 is proposed.

[0050] Embodiment 3: please refer to Figure 4The embodiment provides a mobile coal moisture tester, which comprises all the structures in embodiment 2, wherein the protective sleeve 14 comprises a protective layer 21 and a buffer layer 22 arranged in sequence from the direction of the steel probe 8, the protective layer 21 and the buffer layer 22 are glued together, the protective layer 21 is made of wear-resistant material, such as wear-resistant resin, and the buffer layer 22 is made of material with good insulation and toughness, such as rubber; a plurality of electric absorption strips 23 are arranged in the protective layer 21 and uniformly distributed along the length direction of the protective layer 21, the number of the electric absorption strips 23 can be selected and customized according to actual conditions, the end of the electric absorption strip 23 away from the buffer layer 22 is outwardly penetrated through the protective layer 21, the end of the electric absorption strip 23 close to the buffer layer 22 is in abutment with the buffer layer 22, and the surface of the buffer layer 22 close to the steel probe 8 is coated with an anti-static layer 25; through the foregoing arrangement, the electric absorption strips 23 can absorb static electricity generated when the protective sleeve 14 is in contact with coal and rubbed, the static electricity absorbed by the electric absorption strips 23 is conducted into the buffer layer 22 under the conduction of the electric absorption strips 23, due to the insulation characteristics of the buffer layer 22, that is, the characteristic of infinite resistance, the current passing through the buffer layer 22 is infinitely small, and the detection work of the steel probe 8 is not affected, the anti-static layer 25 can avoid static electricity generated between the steel probe 8 and the protective sleeve 14, so as to ensure the accuracy of the humidity sensor 2 in detecting the humidity of coal through the steel probe 8 and avoid the interference of static electricity.

[0051] Meanwhile, in order to improve the protection effect of the protective sleeve 14, a plurality of micro-bubbles 24 are arranged in the buffer layer 22 and uniformly distributed along the length direction of the buffer layer 22, the micro-bubbles 24 can give the buffer layer 22 good impact absorption capacity, so that the buffer layer 22 can well absorb the pressure brought by coal when the protective sleeve 14 is inserted into the coal, so as to prevent the steel probe 8 from being deformed, broken and the like.

[0052] Since the steel probe in the tester needs to be inserted into coal for a long time to complete the detection of the moisture of the coal, a worker needs to hold the tester all the time to prevent the tester from falling during the detection process; in this way, the labor intensity of the worker is increased, and when some emergencies occur, the worker cannot quickly take corresponding measures due to holding the tester with hands; based on this, embodiment 4 is provided on the basis of embodiment 1, embodiment 2 and embodiment 3.
