The eccentric wheel 7 and the connecting rod 8 are driven by the motor 6, so that the knocking block 10 reciprocates up and down inside the piston cylinder 1, thereby knocking on the weak layer of the slope.

[0033] See also Figure 1 , Figure 3 and Figure 4 Two first chutes 11 are provided on the outer wall of the earth-breaking rod 4, a second chute 12 is provided inside the earth-breaking rod 4, a third chute 13 is provided at the bottom end of the earth-breaking rod 4, and four sampling ports 14 are provided at the bottom end of the third chute 13. The sampling ports 14 are arranged so that when the earth-breaking rod 4 goes deep into the ground, samples can be collected through the sampling ports 14. A sliding rod 15 is slidably connected inside the second chute 12, a handle 16 is fixedly connected to the upper end of the sliding rod 15, and a sampler 17 is fixedly connected to the bottom end of the sliding rod 15. The sampler 17 is arranged to collect samples through the sampling ports 14 and close the sampling ports 14.

[0034] See also Figure 1 , Figure 2 and Figure 4 , handles 18 are fixedly connected on both sides of the motor box 5, and the handles 18 are set for the operator to grasp the device. The end of the rubber ring 3 away from the slider 2 is fixedly connected to the piston cylinder 1, and the rubber ring 3 is set to connect the slider 2 with the piston cylinder 1 and buffer the impact force generated by knocking. The knocking block 10 is slidably set inside the piston cylinder 1, so that the knocking block 10 reciprocates up and down inside the piston cylinder 1, thereby realizing the knocking of the earth-breaking rod 4, and the handle 16 is slidably set inside the first slide groove 11.

[0035] In this embodiment, the weak layer sampling device for open-pit coal mine slope exploration is provided with a slider 2, a motor 6, an eccentric wheel 7, a connecting rod 8 and a knocking block 10. The motor 6 in the device drives the eccentric wheel 7 and the connecting rod 8, so that the knocking block 10 reciprocates up and down inside the piston cylinder 1, thereby knocking the slider 2 and then transmitting the knocking force to the breaking rod 4, thereby knocking on the weak layer of the slope. This knocking action helps to break the soil or rock, making sampling easier, and when the knocking force is transmitted to the operator through the setting of the rubber ring 3, the impact caused by the knocking is buffered, making the operator more comfortable when operating the equipment.

[0036] It should be noted that the rubber ring 3 can be deformed to a certain extent. When the knocking block 10 knocks the slider 2, the shock transmitted to the operator's hand is reduced through the buffering of the rubber block.

[0037] The working principle of the above embodiment is:

[0038] First, the operator grasps the device by the handle 18 to ensure that the device is stably placed at the slope position where sampling is required. The operator starts the motor 6, and the output end of the motor 6 drives the eccentric wheel 7 to rotate. The rotation of the eccentric wheel 7 drives the knocking block 10 to reciprocate up and down inside the piston cylinder 1 through the connecting rod 8 and the rotating seat 9. The up and down movement of the knocking block 10 generates an impact force, which is transmitted to the earth-breaking rod 4 through the slider 2, and then the weak layer of the slope is knocked. Under the knocking action, the earth-breaking rod 4 gradually penetrates into the slope. When the earth-breaking rod 4 penetrates to a predetermined depth, the operator stops the motor 6, and the operator pulls the handle 16 to slide the slide bar 15 in the second slide groove 12. The sampler 17 at the bottom of the slide bar 15 then slides in the third slide groove 13, and collects samples of the weak layer of the slope through the sampling port 14. The design of the sampler 17 allows the sample to be collected and closed when passing through the sampling port 14, thereby ensuring the integrity and representativeness of the sample. After processing the sample, the operator turns off the motor 6, lifts the device by the handle 18, and removes the sample from the sampler 17.
