[0002] Mines include coal mines, metal mines, non-metallic mines, building materials mines and chemical mines, etc. The scale of mines (also known as production capacity) is usually expressed in annual output or daily output. Annual output refers to the amount of ore produced by the mine each year. According to the size of output, mines are divided into three types: large, medium and small. Mines need to be mined. During the mining process, testing and sampling are involved to analyze the content ratio of various components in the minerals to determine the specific status of the resources.

[0003] A Chinese utility model patent proposes a sampling device for detection during mining (Announcement No.: CN 217277020U). During the sampling process, a mobile trolley, a mobile seat, a sampling barrel, a conical drill bit, a spiral blade and multiple conical tooth grooves are used in combination. The sampling barrel and the conical drill bit are rotated to perform sampling drilling, thereby cooperating with the drilling for sampling during mining. When the specified depth is reached, the minerals can enter the sampling barrel for storage as the conical drill bit continues to rotate. The sampling barrel is removed from the sampling hole, and the sampling work for mine detection is completed. However, it lacks an effective safety protection mechanism. When the sampling barrel drill encounters an unusually hard rock layer or a hidden obstacle, the sampling barrel drill cannot continue to drill into the mountain, and the equipment will continue to run, thereby exacerbating equipment damage and even causing safety accidents.

[0022] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0023] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in, Figure 1 It is a structural diagram of the utility model; Figure 2 This is a structural diagram of the utility model from another angle; Figure 3The diagram is a structural diagram of the safety mechanism in the present invention, which includes a base 1, an adjustment mechanism, a moving mechanism, a safety mechanism and a drilling mechanism.

[0024] In the specific implementation process, Figure 1 and Figure 3 As shown, rollers 2 are installed at the four corners of the lower surface of the base 1, and an adjusting mechanism is connected to the base 1, and a moving mechanism is connected to the adjusting mechanism. The moving mechanism includes a servo motor 9, a slide frame 8, a screw rod 10 and a nut slider 20. The adjusting mechanism is fixedly connected to the slide frame 8, and a servo motor 9 is also installed on the adjusting mechanism. The output end of the servo motor 9 passes through the upper surface of the adjusting mechanism and the slide frame 8 and is fixedly connected to the screw rod 10 through a coupling. The lower end of the screw rod 10 is rotatably connected to the inner lower surface of the slide frame 8, and a nut slider 20 is provided on the screw rod 10. A safety mechanism is connected to the nut slider 20, which includes a fixed block 13, a guide rod 23, a limit sleeve 27, a spring 24, a mounting block 14, a press slide rod 22, a fixed rod 25, a top plate 17 and a press switch 21. One end of the nut slider 20 is fixedly connected to the fixed block 13, the fixed block 1 3 is fixedly connected to the lower surface of two symmetrically arranged guide rods 23, and the lower end of the guide rod 23 is threadedly sleeved with a limit sleeve 27. A mounting block 14 is provided below the fixed block 13, and the mounting block 14 is slidably sleeved on the two guide rods 23. A spring 24 is also sleeved on the guide rod 23. The upper surface of the mounting block 14 is fixedly connected to a press slide 22. The upper surface of the fixed block 13 is fixedly connected to the top plate 17 through two symmetrically arranged fixing rods 25. A press switch 21 is installed on the lower surface of the top plate 17. The press slide 22 is located directly below the press switch 21. A drilling mechanism is installed on one side of the mounting block 14. The drilling mechanism includes a motor 15 and a sampling tube drill 16. A motor 15 is installed on one side of the mounting block 14 (the press switch 21 is electrically connected to the servo motor 9 and the motor 15), and the output end of the motor 15 is installed with the sampling tube drill 16.

[0025] It should be noted that: when in use, the servo motor 9 and the motor 15 are started, and the rotation of the servo motor 9 drives the rotation of the screw rod 10, and the rotation of the screw rod 10 causes the nut slider 20 to slide down in the slide frame 8, and the downward movement of the nut slider 20 drives the downward movement of the fixed block 13, and the downward movement of the fixed block 13 drives the downward movement of the mounting block 14, causing the motor 15 to move downward, and the rotation of the motor 15 drives the sampling tube drill 16 to rotate, and then the sampling tube drill 16 rotates to drill into the mountain for sampling. In the drilling process, due to the reverse force, the mounting block 14 slides slightly along the guide rod 23, squeezing the spring 24, and the spring The spring 24 undergoes a certain deformation, and the push slide 22 slides up slightly in the fixed block 13. At this time, the push slide 22 will not squeeze the push switch 21. When the sampling barrel drill 16 encounters an unusually hard rock layer or there is a hidden obstacle and cannot drill into it, the pressure gradually increases, and the mounting block 14 gradually slides up along the guide rod 23. The deformation of the spring 24 becomes larger, and the push slide 22 gradually slides up in the fixed block 13, and finally squeezes the push switch 21, turning off the servo motor 9 and the electric motor 15, and automatically stopping. Then the servo motor 9 is reversed, and the sampling barrel drill 16 is moved out to reselect the sampling location for sampling.

[0026] refer to Figure 1 As shown, the adjustment mechanism includes a frame plate 4, a reduction motor 5, an adjustment shaft 6 and an adjustment block 7. The upper surface of the base 1 is fixedly connected to two symmetrically arranged frame plates 4, and a reduction motor 5 is installed on the side of one of the frame plates 4. The output end of the reduction motor 5 passes through the adjacent frame plate 4 and is fixedly connected to the adjustment shaft 6 through a coupling. The other end of the adjustment shaft 6 is rotatably connected to the side of the other frame plate 4. An adjustment block 7 is sleeved on the adjustment shaft 6. The sliding frame 8 is fixedly connected to the lower surface of the adjustment block 7. The servo motor 9 is installed on the upper surface of the adjustment block 7. The output end of the servo motor 9 passes through the upper surfaces of the adjustment block 7 and the sliding frame 8 and is fixedly connected to the upper end of the screw rod 10 through a coupling.

[0027] It should be noted that: when in use, the rotation of the reduction motor 5 can drive the slow rotation of the adjusting shaft 6, the slow rotation of the adjusting shaft 6 drives the slow rotation of the adjusting block 7, and the slow rotation of the adjusting block 7 finally drives the slow rotation of the sampling barrel drill 16, so that the angle of the sampling barrel drill 16 can be adjusted according to the inclination of the mountain for drilling.

[0028] refer to Figure 2 As shown, a push handle 3 is fixedly connected to the upper surface of the base 1, and the push handle 3 is provided to facilitate the movement of the entire device.

[0029] refer to Figure 1As shown, the sliding frame 8 is connected to a cleaning mechanism, which includes a scraper ring 12 and a connecting rod 11. A matching scraper ring 12 is provided on the sliding sleeve of the sampling tube drill 16. The scraper ring 12 is fixedly connected to the sliding frame 8 through two symmetrically arranged connecting rods 11 (the connecting rod 11 is fixedly connected to the sliding frame 8 by bolts, which facilitates the disassembly and assembly of the connecting rod 11).

[0030] It should be noted that during use, when sampling is completed and the sampling auger 16 is moved out of the mountain, the scraper ring 12 can scrape off the soil on the outer wall of the sampling auger 16 .

[0031] refer to Figure 2 As shown, the two frame plates 4 are fixedly connected by a plurality of parallel reinforcing rods 18 , and the reinforcing rods 18 make the structure of the frame plates 4 more stable.

[0032] refer to Figure 1 As shown, a collection box 19 is fixedly connected to the upper surface of the base 1, and a plurality of evenly distributed partitions 26 are fixedly connected inside the collection box 19. The collection box 19 with the partitions 26 facilitates classification and collection.

[0033] The working principle of the present invention is as follows: when in use, the servo motor 9 and the motor 15 are started, and the rotation of the servo motor 9 drives the rotation of the screw rod 10, and the rotation of the screw rod 10 causes the nut slider 20 to slide down in the slide frame 8, and the downward movement of the nut slider 20 drives the downward movement of the fixed block 13, and the downward movement of the fixed block 13 drives the downward movement of the mounting block 14, causing the motor 15 to move downward, and the rotation of the motor 15 drives the sampling tube drill 16 to rotate, and then the sampling tube drill 16 rotates and drills into the mountain body to take samples, and in the process of drilling In the process, due to the reverse force, the mounting block 14 slides slightly upward along the guide rod 23, squeezing the spring 24. The spring 24 is deformed to a certain extent, and the pressing slide bar 22 slides slightly upward in the fixed block 13. At this time, the pressing slide bar 22 will not squeeze the push switch 21. When the sampling tube drill 16 encounters an unusually hard rock layer or a hidden obstacle that cannot be drilled into, the pressure gradually increases, the sliding distance of the mounting block 14 along the guide rod 23 gradually increases, the deformation of the spring 24 increases, and the pressing slide bar 22 gradually slides upward in the fixed block 13, finally squeezing the push switch 21. Press the push switch 21 to turn off the servo motor 9 and the motor 15, and automatically stop the machine. Then reverse the servo motor 9 and move the sampling tube drill 16 out to select a new sampling location for sampling. In the process of use, when encountering an unusually hard rock layer or a hidden obstacle that cannot be drilled into, it can not only provide buffer protection but also automatically stop the machine, thereby reducing the damage rate of the equipment and the incidence rate of safety accidents. In normal sampling, after the sampling is completed, the servo motor 9 is reversed and the sampling tube drill 16 is moved out of the mountain. Before use, by reducing The rotation of the high-speed motor 5 can drive the slow rotation of the adjusting shaft 6, the slow rotation of the adjusting shaft 6 drives the slow rotation of the adjusting block 7, and the slow rotation of the adjusting block 7 finally drives the slow rotation of the sampling barrel drill 16, so that the angle of the sampling barrel drill 16 can be adjusted according to the inclination of the mountain for drilling, which is convenient for the use of mine detection sampling. During use, when the sampling is completed and the sampling barrel drill 16 is moved out of the mountain, the scraper ring 12 can scrape off the soil on the outer wall of the sampling barrel drill 16, thereby automatically cleaning the outer wall of the sampling barrel drill 16 for easy use.
