Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

The anti-slip mechanism 2 includes a moving frame 202 located inside the core tube 106. The side of the moving frame 202 is fixedly provided with oblique teeth 203. The anti-slip mechanism 2 is used to prevent the sampled rock from sliding off.

[0021] Specifically, Figure 1-Figure 8 As shown, a fixing column 102 is fixedly installed on the top surface of the fixing plate 101 , a fixing frame 103 is movably installed on the outer wall of the fixing column 102 , and a side surface of the fixing frame 103 is fixedly connected to a side surface of a drilling rig 104 .

[0022] In this embodiment, the fixing frame 103 is supported by the fixing column 102 , thereby supporting the drilling rig 104 .

[0023] Specifically, Figure 1-Figure 8 As shown, the inner wall of the core tube 106 is provided with three grooves 201, and three movable frames 202 are provided. The outer walls of the three movable frames 202 are respectively slidably connected with the inner walls of the three grooves 201, and a plurality of helical teeth 203 are provided. Elastic members 204 are respectively fixedly installed on the sides of the three movable frames 202, and the other ends of the plurality of elastic members 204 are respectively fixedly connected with the inner walls of the three grooves 201.

[0024] In this embodiment: the movable frame 202 is limited by the groove body 201, and the inclined teeth 203 are arranged at an upward angle, so that when the inclined teeth 203 squeeze the soil sample in the core tube 106, the soil sample is prevented from falling and the rock sample can be ensured to enter the core tube 106 upward.

[0025] Specifically, Figure 1-Figure 8 As shown, the inner walls of both sides of the three moving frames 202 are respectively provided with groove bodies 205, and the multiple groove bodies 205 are set into special shapes. The upper part of the groove body 205 is arranged obliquely, and the lower part of the groove body 205 is consistent with the elastic expansion and contraction direction of the elastic member 1 204. The lower part of the groove body 205 is used to provide a moving stroke for the moving frame 202, and with the help of the reaction force of the elastic member 1 204, the inclined teeth 203 can provide an upward pressure on the sampled soil, thereby preventing the sampled soil from falling from the sampling position. The inner walls of the three moving frames 202 are respectively slidably installed with connecting strips 206, and the two sides of the three connecting strips 206 are respectively fixedly installed with cylinders 1 207, and the outer walls of the other ends of the multiple cylinders 1 207 are respectively slidably connected with the inner walls of the multiple groove bodies 205.

[0026] In this embodiment: by setting the groove body 205, when the connecting bar 206 drives the cylinder 1 207 to move to the lowermost end of the groove body 205, the movable frame 202 can move freely, and when the connecting bar 206 drives the cylinder 1 207 to move upward on the inner wall of the groove body 205, it drives the movable frame 202 to move and squeeze the elastic member 1 204. At the same time, the movable frame 202 drives the bevel teeth 203 to move, and no longer squeezes the rock sample.

[0027] Specifically, Figure 1-Figure 8 As shown, a fixing groove 213 is opened on the top surface of the core tube 106, and the upper ends of the three connecting bars 206 slide through the inner walls of the upper ends of the three groove bodies 201 and extend to the inside of the fixing groove 213. A circular frame 208 is fixedly installed on the upper ends of the three connecting bars 206, and the side surface of the circular frame 208 is slidably connected to the inner wall of the fixing groove 213, and the top surface of the circular frame 208 contacts the bottom surface of the connecting tube 105.

[0028] In this embodiment, the circular frame 208 is squeezed by the connecting tube 105, and the circular frame 208 drives the connecting strip 206 to move, thereby driving the cylinder 1 207 to move.

[0029] Specifically, Figure 1-Figure 8 As shown, three slot bodies 210 are provided on the inner wall of the fixed slot 213, and L-shaped strips 209 are slidably installed on the inner walls of the three slot bodies 210 respectively. The upper ends of the three L-shaped strips 209 are fixedly connected to the bottom surface of the round frame 208, and sliding rods 211 are slidably installed on the top surfaces of the three L-shaped strips 209 respectively. The two ends of the three sliding rods 211 are respectively fixedly connected to the inner walls of the three slot bodies 210, and the outer walls of the three sliding rods 211 are respectively slidably installed with elastic parts 212, and the two ends of the three elastic parts 212 are respectively fixedly connected to the bottom surfaces of the three L-shaped strips 209 and the inner walls of the lower ends of the three slot bodies 210.

[0030] In this embodiment, the second elastic member 212 applies elastic force to the L-shaped strip 209 , and the elastic force of the second elastic member 212 is greater than the elastic force of the first elastic member 204 , so that the L-shaped strip 209 drives the circular frame 208 to move upward, and drives the connecting strip 206 to move upward.

[0031] The fixing mechanism 3 is arranged below the connecting tube 105 . The fixing mechanism 3 comprises a fixing shell 303 fixedly mounted on the top surface of the core tube 106 . Support plates 311 are arranged on both sides of the fixing shell 303 . The fixing mechanism 3 is used to fix the connecting tube 105 and the core tube 106 .

[0032] Specifically, Figure 1-Figure 11 As shown, three fixed shells 303 are provided, and three groove bodies 301 are provided on the inner wall of the fixed groove 213. Wedge-shaped shells 302 are slidably installed on the inner walls of the three groove bodies 301 respectively. The side surfaces of the three wedge-shaped shells 302 are slidably connected to the outer wall of the circular frame 208. An inclined surface is provided at the contact between the wedge-shaped shell 302 and the circular frame 208 for converting the thrust applied to the wedge-shaped shell 302.

[0033] In this embodiment, the wedge-shaped shell 302 is limited by the groove body 301, so that the movement of the wedge-shaped shell 302 is more stable, and at the same time, the circular frame 208 squeezes the wedge surface of the wedge-shaped shell 302 to move.

[0034] Specifically, Figure 1-Figure 11 As shown, moving blocks 304 are slidably installed on the inner walls of the three trough bodies 301 respectively, and the inner and outer walls of the three moving blocks 304 are slidably connected to the inner walls of the three wedge-shaped shells 302 respectively. The three moving blocks 304 have inclined grooves 306 on both sides, and the inner walls of the two sides of the three wedge-shaped shells 302 are fixedly installed with cylinders 305 respectively, and the outer walls of multiple cylinders 305 are slidably connected to the inner walls of multiple inclined grooves 306 respectively.

[0035] In this embodiment, the inclined groove 306 is provided, and the wedge-shaped shell 302 moves to drive the second cylinder 305 to move, and cooperates with the inclined groove 306 to drive the moving block 304 to move upward.

[0036] Specifically, Figure 1-Figure 11As shown, the top surfaces of the three moving blocks 304 are hinged with two connecting rods 1 310, the inner walls of the upper ends of the three fixed shells 303 are respectively hinged with two connecting rods 2 312, and the top surfaces of the three moving blocks 304 are fixedly installed with elastic parts 307, and the upper ends of the three elastic parts 307 are fixedly connected to the inner walls of the upper ends of the three fixed shells 303.

[0037] In this embodiment, when the movable block 304 moves upward, the second connecting rod 312 is driven to move, and at the same time, the movable block 304 pushes the elastic member 307 to be squeezed, and the elastic member 307 applies elastic force to the movable block 304 .

[0038] Specifically, Figure 1-Figure 11 As shown, placement grooves 308 are respectively provided on both sides of the three fixed shells 303, through grooves 309 are provided on the sides of the multiple placement grooves 308, the outer walls of the multiple connecting rods 1 310 and the outer walls of the multiple connecting rods 2 312 are slidably connected, the other ends of the multiple connecting rods 1 310 and the other ends of the multiple connecting rods 2 312 are respectively hinged to the sides of the multiple support plates 311, a support groove 313 is provided on the bottom surface of the connecting tube 105, and the sides of the multiple support plates 311 are frictionally connected to the inner walls of the support groove 313.

[0039] In this embodiment, the connecting rod 1 310 and the connecting rod 2 312 are provided to drive the support plate 311 to squeeze the inner wall of the support groove 313, and the friction generated makes it difficult for the connecting tube 105 and the core tube 106 to rotate automatically and loosen after being fixed, thereby improving the quality of the connection.

[0040] The specific solution is as follows: before taking soil, the connecting tube 105 is connected to the core tube 106. At this time, the core tube 106 squeezes the round frame 208 into the fixed groove 213. At this time, the round frame 208 drives the connecting strip 206 and the cylinder 1 207 to move downward, and the cylinder 1 207 moves to the bottom of the groove body 205. The elastic member 1 204 pushes the moving frame 202 and the bevel gear 203 to approach the center of the core tube 106. At the same time, when the round frame 208 moves into the fixed groove 213, the round frame 208 squeezes the wedge shell 302 to move, the wedge shell 302 pushes the cylinder 2 305 to move, and the cylinder 2 305 pushes the moving block through the bevel groove 306. 304 moves upward, and the moving block 304 pushes the connecting rod 1 310 to move upward. At the same time, under the joint action of the connecting rod 2 312, the side of the support plate 311 is pushed to squeeze the inner wall of the support groove 313, and the side of the support plate 311 and the inner wall of the support groove 313 produce friction, so that the connection tube 105 and the core tube 106 are fixed more stably. At this time, the soil is drilled by the drill bit 107, and the drilled soil moves upward to the core tube 106 through the inner wall of the drill bit 107. When the sampled soil moves relatively upward in the core tube 106, the soil squeezes the inclined teeth 203, and the inclined teeth 203 move toward the inside of the slot body 1 201, and the inclined teeth 203 push the moving frame 202 to move The elastic member 204 is squeezed, and the soil continues to move upward in the core tube 106. After the soil is taken out, the core tube 106 is taken out of the soil. The elastic force applied by the elastic member 204 to the movable frame 202 pushes the movable frame 202 and the inclined teeth 203 to move toward the middle of the core tube 106. The inclined teeth 203 support and squeeze the outer wall of the sampled soil. The sampled soil is supported and squeezed by the inclined teeth 203 and will not fall from the core tube 106. When the sampled soil is taken out of the core tube 106, the connecting tube 105 is separated from the core tube 106. At this time, the elastic member 212 pushes the L-shaped strip 209 and the round frame 214. 208 moves upward, the circular frame 208 drives the connecting strip 206 and the cylinder 1 207 to move upward, the cylinder 1 207 passes through the slot body 205, drives the moving frame 202 to move into the slot body 1 201, and squeezes the elastic member 1 204, the moving frame 202 drives the inclined teeth 203 to move into the slot body 1 201, when the inclined teeth 203 move to the inside of the slot body 1 201, the inclined teeth 203 no longer contact the outer wall of the sampled soil, the sampled soil cannot be supported and squeezed, and falls from the lower end of the core tube 106 under the action of gravity, thereby ensuring that the sampled soil is relatively complete, which is convenient for the subsequent distinction and detection of soils at different soil depths.

[0041] A person skilled in the art should understand that the discussion of any of the above embodiments is only exemplary; within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
