DETAILED DESCRIPTION

[0018] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0019] Example: A protective device for a sampling rod, such as Figures 1-4 As shown, the system includes a sampling tube 1, an operating component 2, a mounting block 3, a pressure sensor 4, a top block 5, a return spring 6, a conical drill bit 7, a battery 8, a cover plate 9, an alarm 11, and a power assembly. The operating component 2 is mounted on the top of the sampling tube 1. A screw conveyor is installed inside the sampling tube 1. The operating component 2 contains a power device to drive its rotation. Handles are located on both sides of the operating component 2, and a control button is located on the top. The sampling tube 1 has an inlet at the bottom and an outlet at the top. The bottom of the sampling tube 1 is connected to the mounting block 3. The pressure sensor 4 is mounted on the top of the mounting block 3. A reset spring 6 is provided. A top block 5 is slidably connected to the bottom of the mounting block 3. One end of the reset spring 6 is connected to the mounting block 3, and the other end is connected to the top block 5. A conical drill bit 7 is rotatably connected to the bottom of the top block 5. A power component for driving the conical drill bit 7 to rotate is provided inside the top block 5. A battery 8 is installed inside the operating component 2. A cover plate 9 is connected to the operating component 2 by screws. The operating component 2 is provided with a charging port 10, which is wired to the battery 8. An alarm 11 is installed on the operating component 2, which is wired to the pressure sensor 4. The battery 8 supplies power to all electrical equipment.

[0020] like Figure 2 and Figure 4 As shown, the power assembly includes a motor 12, a spline 13, and a maintenance plate 14. The motor 12 is installed inside the top block 5, with its output shaft facing downwards and connected to the spline 13. The motor 12 engages with the tapered drill bit 7 via the spline 13. The design of the spline 13 ensures the stability and efficiency of power transmission. The motor 12 is wired to the control buttons of the operating assembly 2. A notch is provided on one side of the top block 5, at which a removable maintenance plate 14 is installed. The sampling operator can use the control buttons to promptly shut off the motor 12, preventing equipment damage. The maintenance plate 14 is designed for easy maintenance; when the motor 12 requires maintenance, the sampling operator can remove the maintenance plate 14 to quickly troubleshoot or replace components.

[0021] like Figure 1 As shown, it also includes a lighting lamp 15. The operating component 2 is equipped with a lighting lamp 15 on its outer ring. In environments with insufficient light, the sampler can illuminate the work area using the lighting lamp 15 on the operating component 2. The lighting lamp 15 can be turned on and off using a control button.

[0022] As shown in Figure 1 It also includes a sealing plug 16, which is arranged at the charging port 10. After charging, the sealing plug 16 can tightly close the charging port 10 to prevent dust, soil or moisture from entering, thereby protecting the battery 8 and internal circuit from pollution or damage.

[0023] As shown in Figure 1 It also includes a telescopic sleeve 17, which is arranged between the mounting block 3 and the conical drill bit 7. The telescopic sleeve 17 is connected to the top of the mounting block 3 and the bottom of the conical drill bit 7. The telescopic sleeve 17 will automatically expand or contract according to the movement of the top block 5, and always keep the gap between the conical drill bit 7 and the mounting block 3 in a sealed state, effectively preventing soil or debris from entering the inside of the mounting block 3.

[0024] As shown in Figure 1 It also includes a material guiding spiral blade 18, which is arranged at the outer circle of the conical drill bit 7. When the drill bit rotates, the material guiding spiral blade 18 pushes the broken soil and coal mine away, which not only improves the sampling speed, but also reduces the load of the drill bit and prolongs the service life of the equipment.

[0025] The sampler selects a sampling site, then aims the conical drill bit 7 at the sampling site, holds the handle with both hands, turns on the power device and the motor 12 by controlling the button, and the motor 12 drives the conical drill bit 7 to rotate through the spline 13. Moreover, the conical drill bit 7 can push the squeezed soil outwards with the assistance of the material guiding spiral blade 18. As the conical drill bit 7 penetrates, the sampling tube 1 enters the soil, and the broken soil and coal mine enter the gap of the sampling tube 1 at this time. The rotating spiral conveyor transports the sample upwards. As the conical drill bit 7 penetrates deeper, it may encounter hard rock. After the feeding speed is reduced, the sampler pushes the sampling tube 1 through the handle. If it is only a hard coal block, it will be broken. If it is really rock, the conical drill bit 7 is subjected to bi-directional stress, and the pressure is gradually transmitted upwards along the top block 5. When the pressure is transmitted upwards along the top block 5, the reset spring 6 in the mounting block 3 is compressed. When the top block 5 contacts the pressure sensor 4, the alarm 11 lights up, indicating that it cannot continue to penetrate for sampling. If it continues to penetrate, it may damage the sampling equipment. At this time, the sampler turns off the motor 12, and the power device transports the sample out. Then the sampling tube 1 is pulled out.

[0026] During the sampling process, the battery 8 supplies power to the power device, the motor 12, the alarm 11 and the pressure sensor 4. After sampling is completed, the battery 8 is charged through the charging port 10. After charging is completed, the sealing plug 16 plugs the charging port 10. When the top block 5 slides, the telescopic sleeve 17 contracts. When the motor 12 is overhauled, the telescopic sleeve 17 needs to be removed, the access panel 14 is opened, and the illuminating lamp 15 illuminates the control button to ensure the accuracy of the operation.

[0027] The application is described in detail above, and the principles and implementation modes of the application are described by applying specific examples. The above description of the examples is only used to help understand the method of the application and its core idea; meanwhile, for those skilled in the art, according to the idea of the application, the specific implementation modes and application ranges will have changes, and the above description of the specification should not be understood as a limitation on the application.
