[0017] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0018] According to Figures 1-3 As shown, this embodiment provides a 40T scraper sprocket detection tool, including a support base 1, a first shaft rod 2, a second shaft rod 3 and spline teeth 4. A through mounting hole 5 is provided at the upper end of the support base 1. One end of the first shaft rod 2 is inserted into the through mounting hole 5 and extends outwards. A limit end cover 6 is detachably provided at the end of the first shaft rod 2 extending out of the inside of the through mounting hole 5. A second shaft rod 3 is provided at one end of the first shaft rod 2 away from the limit end cover 6. Spline teeth 4 are provided on the outer wall of the second shaft rod 3. The number of the spline teeth 4 is adapted to the number of internal teeth in the 40T scraper sprocket body 7. The diameter of the second shaft rod 3 is larger than that of the first shaft rod 2 and is adapted to the inner diameter of the 40T scraper sprocket body 7. A storage groove 8 is provided inside the support base 1. The storage groove 8 is used to store the detection part structure composed of the first shaft rod 2, the second shaft rod 3 and the spline teeth 4. After storage, the overall structure is compact and occupies a small area, and the storage will ensure that the detection part structure composed of the first shaft rod 2, the second shaft rod 3 and the spline teeth 4 is not damaged, so as to ensure the detection accuracy next time. The diameter of the storage groove 8 is larger than that of the second shaft rod 3. A top cover 9 is detachably provided on the top of the support base 1. A dust cleaning component is provided inside the top cover 9.

[0019] When the 40T scraper sprocket detection tool of the present utility model detects the internal teeth and external teeth of the 40T scraper sprocket body 7, when two 40T scraper sprocket bodies 7 are detected, the internal teeth should exactly form a keyway fit with the adjacent spline teeth 4 on the outer wall of the second shaft rod 3 under standard conditions. If the 40T scraper sprocket body 7 cannot be fitted and installed with the second shaft rod 3, it means that the 40T scraper sprocket body 7 does not meet the standard. When two 40T scraper sprocket bodies 7 can exactly be fitted and installed with the second shaft rod 3, it means that the internal teeth of the two 40T scraper sprocket bodies 7 are in line with the standard. At this time, the external teeth of the two 40T scraper sprocket bodies 7 can be further detected. When detecting the external teeth, a right-angle steel ruler can be used to lean against the external teeth of the two 40T scraper sprocket bodies 7 to make one side of the two external teeth in the same plane. By detecting and observing, it can be conveniently and accurately detected whether the other side of the external teeth of the two 40T scraper sprocket bodies 7 is in the same plane.

[0020] One end of the first shaft rod 2 is provided with an external thread, and the inner wall of the limit end cover 6 is provided with an internal thread adapted to the external thread. One end of the first shaft rod 2 with the external thread extends through the inside of the through hole 5 and is connected to the internal thread inside the limit end cover 6.

An installation groove is provided at the bottom of the top cover 9, and the dust cleaning fan 11 is arranged in the installation groove. After the top cover 9 is installed on the top of the support base 1, the air outlet of the dust cleaning fan 11 points to the inside of the storage groove 8. By arranging the dust cleaning assembly, the dust cleaning fan 11 can be used to blow air to remove impurities from the detection part structure composed of the first shaft rod 2, the second shaft rod 3 and the spline teeth 4 after detection, ensuring that there are no impurities between the adjacent spline teeth 4 of the detection part structure composed of the first shaft rod 2, the second shaft rod 3 and the spline teeth 4 to affect the detection accuracy during the next use.

[0023] An ash outlet 12 communicating with the internal cavity structure of the base 10 is provided below one side of the base 10, and a slope ash guide plate 13 is arranged in the internal cavity structure of the base 10. The lower end of the slope ash guide plate 13 is located at the ash outlet 12. By arranging the ash outlet 12, the impurities blown down by the dust cleaning fan 11 can be led out of the inside of the base 10.

[0024] Fixing jacks 14 are provided at the four corners of the top of the support base 1, and inserting rods 15 adapted to the positions of the fixing jacks 14 are provided at the four corners of the bottom of the top cover 9.
