[0001] The invention relates to the technical field of sampling, in particular to a rock core drilling sampling device for geological disaster investigation. Background Art

[0002] Geological prospecting is the investigation and research activity of exploring and detecting geology through various means and methods to determine the appropriate bearing layer, determine the foundation type according to the bearing capacity of the bearing layer, and calculate the foundation parameters. It is the investigation and research work of discovering industrially significant mineral deposits during the mineral survey, in order to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and provide the mineral reserves and geological data needed for mine construction design. It is the investigation and research work of the geological conditions such as rocks, strata, structures, minerals, hydrology, and landforms in a certain area. When conducting geological prospecting, it is necessary to sample rocks, and rock sampling equipment is needed.

[0003] Geological survey is the exploration and detection of underground rock formations through various means to understand the specific structure of the rock formations and obtain the geological structure of the underground rock formations. During the geological survey, the drill bit moves downward, causing the sample to move upward relative to the drill bit and enter the drill bit. After the drill bit moves to the specified position, drilling is stopped and the drill bit and the sample inside it are removed.

[0004] The existing rock sampling equipment is rather cumbersome in the process of taking out samples after drilling is completed, and samples are mostly taken out by manual hammering, resulting in low work efficiency. Therefore, a new design was made to address this situation. Summary of the invention

[0010] Among them, the composite mechanism includes a composite frame, the inner side of the composite frame is fixedly connected with a sliding column, the outer side of the sliding column is slidably connected with a mobile frame, during the drilling process, the mobile frame slides on the outer side of the sliding column to be lifted and lowered, thereby meeting the function of working requirements, the outer side of the mobile frame away from the composite frame is fixedly connected with a motor, the motor is connected to a docking block, the inner side of the docking block is plugged with a drill rod, so as to achieve drilling and sampling of rocks, the outer side of the motor close to the processing mechanism is fixedly connected with a docking block, the outer side of the docking block away from the motor is plugged with a drill rod, the outer side of the drill rod is provided with a groove, and the outer side of the drill rod away from the motor is fixedly connected with a drill bit Mechanism, a drill bit mechanism is arranged on the outside of the drill rod, and during the drilling process, the drill bit mechanism is used to break larger rocks and guide the rock blocks into the inside of the drill rod, so that the samples can be taken out when the mobile frame is lifted later, so as to facilitate the subsequent processing, the inner side of the drill rod is slidably connected with a pushing mechanism, and the outer side of the docking block close to the drill bit mechanism is fixedly connected with an electric push rod. After the sampling is completed, the sample is on the inside of the drill rod, which makes it cumbersome and difficult to take out. The electric push rod is docked with one side of the pushing mechanism, and the electric push rod is used to apply pressure to the pushing mechanism to achieve the effect of discharging the sample, thereby reducing the difficulty of operation, maintaining the normal operation of the equipment, and improving the operation efficiency.

[0011] Preferably, the pushing mechanism includes a circular block, which slides on the inner side of the drill rod. As the drill rod goes deeper into the ground, the sample lifts the circular block, and the outer side of the circular block is slidably connected to the inner side of the drill rod. A conical block is fixedly connected to the outer side of the circular block close to the drill bit mechanism, and the conical block is connected to the external block, so as to reduce the contact area and reduce the adhesion of materials, so as to facilitate the removal of samples, thereby reducing the adhesion of materials and reducing the residue of materials inside the components, so as to prevent the residue of materials from corroding the components. The outer side of the conical block is fixedly connected to the external block, and the outer side of the circular block is plug-connected with a connecting plate. When the drill rod is moved out of the ground, it is pushed by the electric push rod and the circular groove of the connecting plate, so as to achieve the effect of squeezing the sample, thereby facilitating the removal of the sample, reducing the difficulty of operation, and improving the working efficiency. A circular groove is opened on the outer side of the connecting plate away from the conical block, and a clamping mechanism is fixedly connected to the inner side of the circular groove.

[0012] Preferably, the clamping mechanism includes a trapezoidal bracket, and one side of the outside of the trapezoidal bracket is hinged with a fixing block. When one end of the electric push rod contacts the outside of the trapezoidal bracket, the spring bar is squeezed and contracted, causing the upper side of the trapezoidal bracket to squeeze the outside of the electric push rod, thereby achieving the function of the fixing component. The side of the outside of the fixing block away from the trapezoidal bracket is fixedly connected to one side of the circular groove, so as to facilitate pushing the circular block to slide and prevent it from falling off during operation. The side of the outside of the trapezoidal bracket close to the fixing block is fixedly connected with a spring bar. When the electric push rod retracts, the spring bar restores its elasticity, which is convenient for subsequent repeated operations.

[0013] Preferably, a rotating block is rotatably connected to the side of the outer part of the trapezoidal bracket away from the fixed block. The rotating block is made of silicone material to increase the friction of the component and improve the braking effect on the component. The silicone material has a wear-resistant effect and reduces the wear between the two, thereby extending the service life of the component. A block surface groove is provided on the outer side of the rotating block. The block surface groove is provided and the contact area is increased by providing the groove to improve the friction effect and further improve the fixing effect. At the same time, the groove has a certain anti-slip effect. The rotating block rotates on the outer side of the trapezoidal bracket. When the electric push rod contacts the rotating block, the rotating block rotates appropriately to reduce the inertia generated by the extension and contraction of the component and speed up the stabilization of the component.

[0014] Preferably, a trapezoidal plate is fixedly connected to the inner wall of the outer side of the trapezoidal bracket close to the rotating block, and a silicone block is fixedly connected to the outer side of the trapezoidal plate close to the rotating block. During the rotation of the rotating block, the rotating block is frictionally braked by the silicone block, thereby slowing down the rotation effect of the component, and by slowing down the rotation speed of the component, the braking effect of the component is accelerated.

[0015] Preferably, the drill bit mechanism includes a drill bit housing, one side of the outside of the drill bit housing is fixedly connected to the outside of the drill rod, and in the process of the drill rod being driven to rotate by the motor, the tooth mark block drills holes in the ground, thereby improving the drilling efficiency of the component, the side of the outside of the drill bit housing away from the drill rod is fixedly connected with a tooth mark block, the inner side of the drill bit housing is fixedly connected with a funnel plate, the rock blocks are guided by the funnel plate to speed up the sampling speed, the outer side of the funnel plate is fixedly connected with a spherical block, the spherical block rotates with the funnel plate, thereby grinding larger stones, thereby achieving the effect of crushing the rock blocks, thereby facilitating rock sampling and improving the sampling speed.

[0016] Preferably, the processing mechanism includes a processing base, the top of the processing base is fixedly connected to a telescopic rod, and a spring coil is sleeved on the telescopic rod to achieve a shock-absorbing and buffering effect, thereby reducing the amplitude caused by the collision of components, so as to achieve a supporting effect on the object and keep the components stable. The side of the telescopic rod away from the processing base is fixedly connected to an arc plate. During the descent of the drill rod, the arc plate is used to constrain it to prevent deviation during the descent process, which affects the drilling efficiency and easily affects the sampling quality. The arc plates correspond to each other and play a certain pre-positioning role, so that it can be checked whether the components remain straight. The side of the telescopic rod away from the arc plate is sleeved with a spring coil.

[0017] Preferably, a connecting bracket is fixedly connected to the side of the outer side of the arc plate away from the telescopic rod, and keeps rotating during the rising process of the drill rod, so that the surface of the component rubs against the surface of the friction column, so as to achieve the effect of cleaning surface impurities. Impurities adhere to the surface of the component for a long time, which is easy to corrode the surface of the component, thereby reducing the performance of the component. A friction column is rotatably connected between the opposite surfaces of the connecting bracket, and the surface of the component is rubbed by the friction column, so that impurities on the surface of the component are peeled off, thereby extending the service life of the component. A cylindrical groove is provided on the outer side of the friction column. By providing the cylindrical groove and increasing the contact area through the groove, the friction effect on the surface of the component is improved, and the cleaning effect is further improved. At the same time, the groove has a certain heat dissipation effect to avoid local overheating caused by excessive friction, which leads to a decrease in component performance.

[0018] Preferably, the spraying mechanism includes a spraying frame. During the rising process of the drill rod, water flows from the water pipe into the inside of the square tube, and then sprays from the surface of the compression port, so as to flush the surface of the component and clean the component. The bottom of the spraying frame is fixedly connected to the top of the processing base. While the drill rod is kept in a rotating state during the rising process, it can achieve a uniform spraying effect, remove some fine impurities, and avoid corrosion and rust of the components. One side of the outside of the spraying frame is fixedly connected to the square tube. During the process of drilling holes in rocks by the drill rod to take samples, the surface temperature of the components increases. Therefore, spraying water has a certain cooling effect, and spraying water has a certain dust reduction effect, thereby optimizing the working environment. A compression port is opened on the side of the outside of the square tube away from the spraying frame. The compression port adopts a structure with one end wide and the other end narrow. By compressing the pipe diameter, the water flow rate is increased, thereby improving the spraying efficiency. The side of the outside of the spraying frame away from the square tube is fixedly connected to the water pipe.

[0019] The present invention provides a rock core sampling device for geological disaster investigation, which has the following beneficial effects:

[0020] 1. The rock core sampling equipment for geological disaster investigation is designed with a composite mechanism. The motor is connected to the docking block, and the drill rod is inserted into the inner side of the docking block to achieve the purpose of drilling and sampling the rock. During the drilling process, the mobile frame slides on the outer side of the sliding column to be lifted and lowered to meet the work needs. A drill bit mechanism is arranged on the outer side of the drill rod. During the drilling process, the drill bit mechanism can crush larger rocks and guide the rock blocks into the inner side of the drill rod so that the samples can be taken out when the mobile frame is lifted later. This is convenient for subsequent processing. After the sampling is completed, the sample is on the inner side of the drill rod, which makes it cumbersome and difficult to take out. The electric push rod is docked with one side of the pushing mechanism, and the electric push rod is used to press the pushing mechanism to discharge the sample, thereby reducing the difficulty of the operation, maintaining the normal operation of the equipment, and improving the operation efficiency.

[0021] 2. The rock core sampling equipment for geological disaster investigation is designed with a clamping mechanism. When one end of the electric push rod contacts the outer side of the trapezoidal bracket, the spring bar is squeezed and contracted, causing the upper side of the trapezoidal bracket to squeeze the outer side of the electric push rod, thereby achieving the function of fixing the component, thereby facilitating the sliding of the circular block to prevent it from falling off during operation. When the electric push rod retracts, the spring bar recovers its elasticity, which is convenient for subsequent repeated operations. The rotating block is made of silicone material to increase the friction of the component and improve the braking effect on the component. The silicone material has a wear-resistant effect and reduces the wear between the two, thereby extending the service life of the component. By opening a groove on the block surface, the contact area is increased by opening a groove to improve the friction effect and further improve the fixing effect. At the same time, the groove has a certain anti-slip effect. The rotating block rotates on the outer side of the trapezoidal bracket. When the electric push rod contacts the rotating block, the rotating block rotates appropriately to slow down the inertia generated by the expansion and contraction of the component and accelerate the stabilization effect of the component. During the rotation of the rotating block, the rotating block is frictionally braked by the silicone block to slow down the rotation effect of the component. By slowing down the rotation speed of the component, the braking effect of the component is accelerated.

[0022] 3. The rock core sampling equipment for geological disaster investigation is designed with a drill bit mechanism. When the motor drives the drill rod to rotate, the tooth mark block drills holes in the ground, thereby improving the drilling efficiency of the components. At the same time, the rock blocks are guided by the funnel plate to speed up the sampling speed. At the same time, the spherical block rotates with the funnel plate to grind larger stones, thereby crushing the rock blocks, thereby facilitating rock sampling and increasing the sampling speed.

[0023] Fourth, the rock core sampling equipment for geological disaster investigation is designed with a processing mechanism. During the descent of the drill rod, the arc plate is used for restraint to prevent the descent process from deflecting, affecting the drilling efficiency and easily affecting the sampling quality. Secondly, the arc plates correspond to each other, which plays a certain pre-positioning role, so that it can be checked whether the components remain straight. The spring ring is set on the telescopic rod to achieve the effect of shock absorption and buffering, thereby reducing the amplitude caused by the collision of components, so as to achieve the support effect of the object and keep the components stable at the same time. During the rise of the drill rod, the rotation state is maintained so that the surface of the component and the surface of the friction column are rubbed to achieve the effect of cleaning surface impurities. Impurities adhere to the surface of the component for a long time and are likely to cause corrosion to the surface of the component, thereby reducing the performance of the component. Therefore, the surface of the component is rubbed by the friction column, so as to peel off the impurities on the surface of the component and extend the service life of the component. Secondly, by opening a cylindrical groove and increasing the contact area by grooving, the friction effect on the surface of the component is improved, and the cleaning effect is further improved. At the same time, the grooving has a certain heat dissipation effect to avoid excessive friction causing local overheating, which leads to the degradation of component performance.

[0024] 5. The rock core sampling equipment for geological disaster investigation is designed with a spraying mechanism. During the rising process of the drill rod, water flows from the water pipe into the inside of the square tube, and then sprays from the surface of the compression port, so as to flush the surface of the components and clean the components. At the same time, while the drill rod remains in a rotating state during the rising process, it can achieve a uniform spraying effect to remove some fine impurities and prevent corrosion and rust of the components. Secondly, during the process of the drill rod drilling holes in the rock to take samples, the surface temperature of the components will increase. Therefore, spraying water can achieve a certain cooling effect, and spraying water can achieve a certain dust reduction effect, thereby optimizing the working environment. The compression port adopts a structure with one end wide and the other end narrow. By compressing the pipe diameter, the water flow rate is increased, thereby improving the spraying efficiency.

[0036] The first embodiment, as Figures 1 to 3 As shown, the present invention provides a technical solution: a rock core sampling device for geological disaster investigation, comprising a composite mechanism 1, the composite mechanism 1 is used to sample rocks;

[0037] A processing mechanism 2, the processing mechanism 2 is used to rub the composite mechanism 1;

[0039] The bottom of the composite mechanism 1 is fixedly connected to the outer side of the processing mechanism 2, and the top of the processing mechanism 2 is fixedly connected to the bottom of the spraying mechanism 3;

[0040] Among them, the composite mechanism 1 includes a composite frame 11, a sliding column 12 is fixedly connected to the inner side of the composite frame 11, a mobile frame 13 is slidably connected to the outer side of the sliding column 12, a motor 14 is fixedly connected to the side of the mobile frame 13 away from the composite frame 11, a docking block 15 is fixedly connected to the side of the motor 14 close to the processing mechanism 2, a drill rod 17 is plugged into the side of the docking block 15 away from the motor 14, a groove is provided on the outer side of the drill rod 17, a drill bit mechanism 19 is fixedly connected to the side of the drill rod 17 away from the motor 14, a pushing mechanism 18 is slidably connected to the inner side of the drill rod 17, and an electric push rod 16 is fixedly connected to the side of the docking block 15 close to the drill bit mechanism 19. The motor 14 is connected to the docking block 15, and the drill rod 17 is inserted into the inner side of the docking block 15, so as to achieve the purpose of drilling and sampling of rocks. During the drilling process, the mobile frame 13 slides on the outer side of the sliding column 12 to perform lifting and lowering, thereby meeting the function of working requirements. A drill bit mechanism 19 is arranged on the outer side of the drill rod 17. During the drilling process, the drill bit mechanism 19 is used to break larger rocks and guide the rock blocks into the inner side of the drill rod 17, so that the samples can be taken out when the mobile frame 13 is lifted later, so as to facilitate subsequent processing. After the sampling is completed, the samples are on the inner side of the drill rod 17, which makes it more cumbersome and difficult to take out. The electric push rod 16 is docked with one side of the pushing mechanism 18, and the electric push rod 16 is used to press the pushing mechanism 18 to achieve the function of discharging the sample, thereby reducing the difficulty of operation, maintaining the normal operation of the equipment, and improving the operation efficiency.

[0041] The second embodiment is based on the first embodiment. Figures 4 to 6As shown, the pushing mechanism 18 includes a circular block 181, the outer side of the circular block 181 is slidably connected to the inner side of the drill rod 17, the outer side of the circular block 181 is fixedly connected to a conical block 182 on the side close to the drill bit mechanism 19, the outer side of the conical block 182 is fixedly connected to an external block 183, the outer side of the circular block 181 is plug-connected to a connecting plate 184, the outer side of the connecting plate 184 is provided with a circular groove 185 on the side away from the conical block 182, and the inner side of the circular groove 185 is fixedly connected to a clamping mechanism 186. The circular block 181 slides on the inside of the drill rod 17. As the drill rod 17 goes deeper into the ground, the sample lifts the circular block 181. When the drill rod 17 moves out of the ground, the electric push rod 16 and the circular groove 185 of the connecting plate 184 are pushed to squeeze the sample, thereby facilitating the removal of the sample, reducing the difficulty of operation, and improving the operation efficiency. The conical block 182 is connected to the external block 183 to reduce the contact area and reduce the adhesion of the material, thereby facilitating the removal of the sample, thereby reducing the adhesion of the material and reducing the residual material inside the component to prevent the residual material from corroding the component.

[0042] The clamping mechanism 186 includes a trapezoidal bracket 1861, a fixed block 1862 is hingedly connected to one side of the outer side of the trapezoidal bracket 1861, a side of the outer side of the fixed block 1862 away from the trapezoidal bracket 1861 is fixedly connected to one side of the circular groove 185, and a spring bar 1863 is fixedly connected to one side of the outer side of the trapezoidal bracket 1861 close to the fixed block 1862. When one end of the electric push rod 16 contacts the outer side of the trapezoidal bracket 1861, the spring bar 1863 is squeezed and contracted, causing the upper side of the trapezoidal bracket 1861 to squeeze the outer side of the electric push rod 16, thereby achieving the function of fixing the component, thereby facilitating the circular block 181 to slide and prevent it from falling off during operation. When the electric push rod 16 retracts, the spring bar 1863 recovers its elasticity, facilitating subsequent repeated operations.

[0043] The outer side of the trapezoidal bracket 1861 away from the fixed block 1862 is rotatably connected with a rotating block 1864, and a block surface groove 1865 is provided on the outer side of the rotating block 1864. The rotating block 1864 is made of silicone material to increase the friction of the components, improve the braking effect on the components, and the silicone material has a wear-resistant effect, reducing the wear between the two, thereby extending the service life of the components. By opening the block surface groove 1865, the contact area is increased by opening the groove, thereby improving the friction effect, further improving the fixing effect, and the groove has a certain anti-slip effect. The rotating block 1864 rotates on the outer side of the trapezoidal bracket 1861. When the electric push rod 16 contacts the rotating block 1864, the rotating block 1864 rotates appropriately to reduce the inertia generated by the expansion and contraction of the components and accelerate the stabilization effect of the components.

[0044] A trapezoidal plate 1866 is fixedly connected to the inner wall of the outer side of the trapezoidal bracket 1861 near the rotating block 1864, and a silicone block 1867 is fixedly connected to the outer side of the trapezoidal plate 1866 near the rotating block 1864. During the rotation of the rotating block 1864, the silicone block 1867 performs friction braking on the rotating block 1864, thereby slowing down the rotation effect of the component, and by slowing down the rotation speed of the component, the braking effect of the component is accelerated.

[0045] The drill mechanism 19 includes a drill housing 191, one side of the outside of the drill housing 191 is fixedly connected to the outside of the drill rod 17, a tooth mark block 192 is fixedly connected to the side of the outside of the drill housing 191 away from the drill rod 17, a funnel plate 193 is fixedly connected to the inside of the drill housing 191, and a spherical block 194 is fixedly connected to the outside of the funnel plate 193. In the process of driving the drill rod 17 to rotate by the motor 14, the tooth mark block 192 drills holes in the ground, thereby improving the drilling efficiency of the component, and at the same time, the funnel plate 193 guides the rock blocks to speed up the sampling speed, and at the same time, the spherical block 194 rotates with the funnel plate 193, so as to grind the larger stones, thereby achieving the effect of crushing the rock blocks, thereby facilitating the sampling of rock blocks and improving the sampling speed.

[0046] The third embodiment is based on the first and second embodiments. Figures 7 to 9 As shown, the processing mechanism 2 includes a processing base 21, a telescopic rod 22 is fixedly connected to the top of the processing base 21, a curved plate 24 is fixedly connected to the side of the telescopic rod 22 away from the processing base 21, and a spring ring 23 is sleeved on the side of the telescopic rod 22 away from the curved plate 24. During the descent of the drill rod 17, the curved plate 24 is used to constrain it to prevent the descent process from deflecting, which affects the drilling efficiency and the sampling quality. Secondly, the curved plates 24 correspond to each other, which plays a certain pre-positioning role, and can check whether the components are kept in a straight state. The spring ring 23 is sleeved on the telescopic rod 22 to achieve the effect of shock absorption and buffering, thereby reducing the amplitude caused by the collision of the components, thereby achieving the support effect of the object and keeping the components stable.

[0047] The side of the arc plate 24 away from the telescopic rod 22 is fixedly connected with a connecting bracket 25, and the friction column 26 is rotatably connected between the opposite surfaces of the connecting bracket 25, and a cylindrical groove 27 is provided on the outer side of the friction column 26. During the rising process of the drill rod 17, the rotation state is maintained so that the surface of the component rubs against the surface of the friction column 26, so as to achieve the effect of cleaning the surface impurities. Impurities adhere to the surface of the component for a long time, which is easy to cause corrosion to the surface of the component, thereby reducing the performance of the component. Therefore, the surface of the component is rubbed by the friction column 26, so that the impurities are peeled off from the surface of the component, and the service life of the component is extended. Secondly, by opening the cylindrical groove 27, the contact area is increased by grooving, so as to improve the friction effect on the surface of the component, further improve the cleaning effect, and at the same time, the grooving has a certain heat dissipation effect, avoiding excessive friction and local overheating, resulting in reduced component performance.

[0048] The spraying mechanism 3 includes a spraying frame 31, the bottom of the spraying frame 31 is fixedly connected to the top of the processing base 21, a square tube 32 is fixedly connected to one side of the outside of the spraying frame 31, a compression port 33 is opened on the side of the outside of the square tube 32 away from the spraying frame 31, and a water pipe 34 is fixedly connected to one side of the outside of the spraying frame 31 away from the square tube 32. During the rising process of the drill rod 17, water flows from the water pipe 34 into the interior of the square tube 32, and then is sprayed from the surface of the compression port 33, so as to flush the surface of the components and clean the components. At the same time, when the drill rod 17 is kept in a rotating state during the rising process, it can achieve the effect of uniform spraying, remove some fine impurities, and prevent the components from corrosion and rust. Secondly, during the process of the drill rod 17 drilling holes for rock sampling, the surface temperature of the components increases. Therefore, the spraying of water flow has a certain cooling effect, and the spraying of water flow has a certain dust reduction effect, thereby optimizing the working environment. The compression port 33 adopts a structure with one end wide and the other end narrow. By compressing the pipe diameter, the water flow velocity is increased, thereby improving the spraying efficiency.

[0049] When in use, the drill rod 17 is docked with the docking block 15, and the motor 14 drives the drill rod 17 to rotate, so that the drill head mechanism 19 drills the ground, and the mobile frame 13 rises and falls on the surface of the sliding column 12 to control the drilling depth, thereby forming a sampling operation for rock drilling as a whole. During the process of the drill rod 17 descending, it contacts the surface of the processing mechanism 2, and the processing mechanism 2 plays a role in fixing the drilling angle. Thereby, it takes effect during the surface drilling process to prevent the components from being offset, helps to correct the drilling angle, and maintains the stability of the drilling. When the drill bit mechanism 19 drills the ground, water is sprayed through the spraying mechanism 3 to achieve the effect of dust removal and dust reduction, avoid dust dispersion during the drilling process, and prevent workers from inhaling smoke and dust into their lungs, which can easily cause harm to the human body. When the drill bit mechanism 19 goes deep into the ground to work, it guides the sampled material into the inside of the drill rod 17. During the entry process, there are large rock blocks, which are crushed by the drill bit mechanism 19 to achieve the effect of controlling the size of the sampled rock blocks and prevent blockage inside the component. After the rock sampling is completed, the mobile frame 13 is raised on the surface of the sliding column 12, while keeping the drill rod 17 in a rotating state. , and frictionally adapts with the surface of the friction column 26 inside the processing mechanism 2, while the spraying mechanism 3 continues to operate. First, the surface of the component is flushed by the spraying mechanism 3. On the one hand, the surface temperature of the component is reduced for cooling. On the other hand, the softer impurities on the surface of the component are removed by flushing to keep the equipment clean. Secondly, the friction column 26 rotates and rubs, so as to frictionally clean the more stubborn rock particles to prevent impurities from adhering to the surface of the component for a long time, which may easily cause corrosion and rust to the component and affect the service life of the component. Finally, the drill rod 17 stops rotating, so that the pushing mechanism 18 calibrates the electric push rod 16, and the electric push rod 16 slides the pushing mechanism 18 on the inside of the drill rod 17, so as to achieve the effect of pushing out the internal sampling rock block, reduce the difficulty of manual knocking sampling, and thus improve the working efficiency.
