The protective plate 6 plays a protective role in the detection process, effectively preventing the coal mine sample from splashing outward when broken, causing harm to the staff.

[0025] Example: Refer to Figure 1-3 As shown, a coal mine geological hardness detection device of the present embodiment includes a base 1, a detection platform 2 is arranged in the middle of the upper end of the base 1, a plurality of groups of detection holes 3 are arranged on the upper end surface of the detection platform 2, and the plurality of groups of detection holes 3 are distributed in a circular array, and a pressure detector 4 is arranged at the inner bottom of the detection hole 3, and the pressure detector 4 can record the pressure value of the sample in the detection hole 3.

[0026] A pressing mechanism is provided in the middle of the upper end of the detection platform 2, including multiple groups of hydraulic rods 11, and the multiple groups of hydraulic rods 11 are correspondingly distributed in the middle of the upper ends of the multiple groups of detection holes 3. A pressing block 12 is provided at the output end of the hydraulic rod 11. The pressing block 12 is pushed downward by the hydraulic rod 11, and the pressing block 12 can be pushed into the detection hole 3, thereby realizing the pressing of the coal mine sample placed in the detection hole 3.

[0027] Furthermore, a protective mechanism is disposed on the periphery of the testing platform 2, including protective plates 6. The protective plates 6 are distributed in a ring shape around the testing platform 2, and the protective plates 6 play a protective role.

[0028] Two groups of first cylinders 5 are provided at the bottom end of the testing platform 2. The two groups of first cylinders 5 are fixedly installed in the inner middle part of the base 1. The output ends of the first cylinders 5 are fixedly connected to the bottom of the testing platform 2. The first cylinders 5 are used to drive the testing platform 2 to move up and down.

[0029] The pressing mechanism further includes a mounting seat 10 , which is circular and located in the middle of the upper end of the testing platform 2 . A plurality of hydraulic rods 11 are mounted in a circular array in the middle of the inner side of the mounting seat 10 .

[0030] A second cylinder 9 is provided in the middle of the top of the mounting seat 10, and the second cylinder 9 is used to drive the pressing mechanism to perform lifting movements. When the output end of the second cylinder 9 is pushed, the mounting seat 10 can be lowered to the inside of the protective plate 6. When the output end of the second cylinder 9 retracts, the mounting seat 10 is driven to rise, thereby facilitating the staff to put samples into the detection hole 3 or clean the inside of the detection hole 3.

[0031] A support seat 7 is provided at the side end of the base 1, and a top plate 8 is provided on one side of the top end of the support seat 7. The top plate 8 is located in the middle of the upper end of the base 1, and the pressing mechanism is arranged in the middle of the bottom end of the top plate 8. The base of the second cylinder 9 is fixedly installed in the middle of the upper end of the top plate 8.

[0035] The working principle of the utility model is:

[0036] When hardness testing of coal samples is required, firstly, a plurality of coal samples are placed in a plurality of testing holes 3 respectively, and then two groups of first air cylinders 5 are started, and the two groups of first air cylinders 5 are retracted to drive the testing platform 2 to descend.

[0037] At this time, the second cylinder 9 is started to push the mounting base 10 downward until the mounting base 10 drops into the protective plate 6, and then a plurality of hydraulic rods 11 are started. When the pressing block 12 enters the detection hole 3 under the push of the hydraulic rod 11, the detection sample is pressed until the sample is broken, and the pressure detector 4 located at the bottom inner side of the detection hole 3 records the pressure on the sample, thereby calculating the hardness of the sample.

[0038] Through the above structure, multiple samples can be tested for hardness separately, so as to effectively improve the accuracy of the test value. In addition, when the coal sample is pressed by the pressing block 12 and breaks, the fragments will splash under the strong pressure. At this time, by providing a protective plate 6, the splashing fragments can be protected and resisted, effectively preventing the coal sample from splashing outward when broken, causing safety problems.
