[0014] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0016] like Figures 1 to 6 As shown, it is a structural diagram of a geological surveyor for geological engineering provided by an embodiment of the present invention, comprising a cylinder 1, a fixing plate 4, a dynamic detection mechanism 200, a synchronous crushing mechanism 300 and an anti-blocking feeding mechanism 400, wherein a drill rod 2 is rotatably installed inside the cylinder 1, and the drill rod 2 is driven by a motor 1 arranged at the top of the cylinder 1, and a guide outlet 3 is also provided on the top side of the cylinder 1; the fixing plates 4 are symmetrically arranged on both sides of the cylinder 1, and a depth adjustment mechanism 100 is installed on the cylinder 1 and the fixing plates 4, and when the depth adjustment mechanism 100 is working, the cylinder 1 is pushed to move in the height direction along the fixing plates 4; the dynamic detection mechanism 200 is arranged between the cylinder 1 and On the fixed plate 4, a plurality of detection rods 25 are installed at the free end of the dynamic detection mechanism 200, and the detection rods 25 are slidably connected to the cylinder 1. When the depth adjustment mechanism 100 rises and falls, the dynamic detection mechanism 200 pushes the detection rods 25 to continuously embed along the cylinder 1 for detection; the synchronous crushing mechanism 300 is installed on the transverse plate 18 and the gear shaft three 19 in the dynamic detection mechanism 200, and crushes the material discharged from the outlet 3 when the gear shaft three 19 rotates; the anti-blocking feeding mechanism 400 is arranged on the outside of the cylinder 1, and the anti-blocking feeding mechanism 400 rises and falls synchronously with the cylinder 1, and automatically collects and exports the samples dropped after being crushed by the synchronous crushing mechanism 300.

[0017] In one example of the present invention, a base plate 15 is hinged on the side of the fixed plate 4, and the base plate 15 is arranged on the walking equipment. A telescopic member 16 is fixedly installed on the base plate 15, and the free end of the telescopic member 16 is connected to the fixed plate 4. The telescopic member 16 is also electrically connected to an external controller 35, so that the inclination angle of the fixed plate 4 and the cylinder 1 can be adjusted as needed before and after use, thereby realizing convenient storage and transportation of the whole.

[0018] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the depth adjustment mechanism 100 includes a gear shaft 5, a tooth plate 6, a V-shaped rod 7, a limit block 8 and a limit groove 9; The gear shaft 1 5 is rotatably mounted on the fixed plate 4, the gear shaft 1 5 is meshed with the toothed plate 6 mounted on the outer side of the cylinder 1, and the gear shaft 1 5 is driven by an external motor 2; A V-shaped rod 7 is fixedly mounted on the fixing plate 4 , and both ends of the V-shaped rod 7 are fixedly connected to limit blocks 8 , which are slidably connected to limit grooves 9 provided on the tooth plate 6 to ensure stable movement of the cylinder 1 .

[0019] In one embodiment of the present invention, when the external motor 2 is working, it drives the gear shaft 1 5 to rotate along the fixed plate 4. Since the gear shaft 1 5 is engaged with the tooth plate 6, the tooth plate 6 and the cylinder 1 can be driven to move in the height direction. At the same time, the limit blocks 8 at both ends of the V-rod 7 slide along the limit grooves 9 opened on the tooth plate 6.

[0020] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the depth adjustment mechanism 100 further includes a horizontal rod 10, a vertical rod 11, a pulley 12, a synchronous belt 13 and a gear shaft 2 14; The crossbar 10 is fixedly connected to the V-shaped bars 7 on both sides, and two vertical bars 11 are installed on the crossbar 10, and the bottom of each vertical bar 11 is rotatably installed with a gear shaft 2 14; A pulley 12 is installed at the end of the gear shaft 1 5 , and the pulley 1 12 and the pulley 2 installed at the end of the gear shaft 2 14 are in the same plane, and the pulley 1 12 and the pulley 2 are connected through a synchronous belt 13 .

[0021] In one embodiment of the present invention, when the gear shaft 15 on one side rotates, the pulley 12 at the corresponding position is driven to rotate synchronously. The pulley 12 also drives the pulley 2 and the gear shaft 2 14 to rotate along the vertical rod 11 through the synchronous belt 13. The two gear shafts 2 14 are engaged, which can make the gear shafts 5 at both ends rotate in opposite directions, so that the cylinder 1 can be stably lifted and lowered when subjected to force.

[0022] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, as another preferred embodiment of the present invention, the dynamic detection mechanism 200 includes a longitudinal plate 17, a transverse plate 18, a gear shaft 3 19, a concave tooth portion 20, an L-shaped rod 21, a straight tooth portion 22 and a torsion spring 23; The longitudinal plate 17 is fixedly mounted on the side of the fixed plate 4, and the longitudinal plate 17 is slidably connected to the transverse plate 18 mounted on the side of the cylinder 1. The side of the transverse plate 18 is rotatably mounted with a gear shaft 3 19, and the gear shaft 3 19 is meshed with a concave tooth portion 20 arranged on the inner side of the longitudinal plate 17, and the cross bars 10 are arranged at equal intervals; The L-shaped rod 21 is arranged at the bottom of the gear shaft 3 19, and a straight tooth portion 22 meshing with the gear shaft 3 19 is provided on the L-shaped rod 21; The end of the gear shaft 3 19 is also equipped with a torsion spring 23 connected to the horizontal plate 18; A suspension bracket 24 is also installed on the top of the L-shaped rod 21. The suspension bracket 24 is slidably connected to a transverse groove provided on the transverse plate 18, so that the L-shaped rod 21 can be subjected to force and move smoothly in the horizontal direction.

[0023] In one example of the present invention, when the cylinder 1 is raised or lowered, the transverse plate 18 slides along the longitudinal plate 17. Since the gear shaft three 19 is meshed with the concave tooth portion 20, the gear shaft three 19 can be driven to rotate along the transverse plate 18. The torsion spring 23 is elastically deformed under force. When the gear shaft three 19 rotates, it also pushes the L-shaped rod 21 and the suspension frame 24 to slide in the horizontal direction along the transverse plate 18. When the gear shaft three 19 moves to the gap between the adjacent concave tooth portions 20, the torsion spring 23 gradually returns to its original state, causing the L-shaped rod 21 and the detection rod 25 to move in the opposite direction. The above process is repeated in this way. The set detection rod 25 can be used to detect the rising sample, and multiple detection rods 25 can select detection modules with different components to facilitate the simultaneous detection of multiple sample components.

[0024] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the synchronous crushing mechanism 300 includes a pulley 3 26, a synchronous belt 27, a pulley 4 28 and a crushing knife 29; The pulley three 26 is fixedly mounted on the shaft end of the gear shaft three 19, and a rotating shaft is rotatably mounted on the side of the horizontal plate 18, and a pulley four 28 in the same plane as the pulley three 26 is fixedly mounted on the rotating shaft, and the pulley four 28 is connected to the pulley three 26 through a synchronous belt two 27; A crushing knife 29 is also installed on the rotating shaft, so that when the gear shaft 3 19 rotates, the crushing knife 29 is driven to rotate synchronously to crush the discharged sample.

[0025] In one embodiment of the present invention, the crushing knives 29 are arranged along the axis of the rotating shaft, and the number is adjusted as needed. In addition, in order to increase the rotation speed of the crushing knives 29, the diameter ratio of the pulley three 26 and the pulley four 28 can be appropriately adjusted to facilitate the high-speed rotation of the crushing knives 29; When in use, the gear shaft three 19 drives the pulley three 26 to rotate synchronously when it rotates. The pulley three 26 also drives the pulley four 28 and the crushing knife 29 to rotate through the synchronous belt two 27. The crushing knife 29 is set to crush the sample discharged from the outlet 3, and the crushed sample is discharged outward along the anti-blocking feeding mechanism 400 under the action of gravity.

[0026] like Figure 1 As shown, as another preferred embodiment of the present invention, the anti-blocking feeding mechanism 400 includes a blanking plate 30, a spiral feeding cylinder 31, a feeding port 32, a support rod 33 and a guide cylinder 34; The blanking plate 30 is arranged outside the cylinder 1 and located at the bottom end of the outlet 3; The cylinder 1 is connected to the spiral feeding cylinder 31 through an external support rod 33. The top of the spiral feeding cylinder 31 is provided with a feed port 32 for receiving the sample dropped from the blanking plate 30. A discharge tube 34 is installed at the end of the spiral feeding tube 31 to discharge the crushed sample outward.

[0027] In one embodiment of the present invention, the crushed sample moves along the drop plate 30, enters the spiral feed cylinder 31 along the feed port 32 when it moves to the end, and moves along the spiral feed cylinder 31 to be finally discharged from the outlet cylinder 34. At the same time, the reciprocating L-shaped rod 21 is also in contact with the inner wall of the spiral feed cylinder 31 during operation, so as to accelerate the discharge of the sample and avoid blockage.

[0028] In summary, during surveying, the motor 1 at the top of the cylinder 1 drives the drill rod 2 to rotate in the cylinder 1 to achieve drilling work. When the motor 2 is working, it drives the gear shaft 1 5 to rotate along the fixed plate 4, and the pulley 12 at the corresponding position rotates synchronously. The pulley 12 also drives the pulley 2 and the gear shaft 2 14 to rotate along the vertical rod 11 through the synchronous belt 1 13. The two gear shafts 2 14 are meshed, which can make the gear shafts 1 5 at both ends rotate in the opposite direction. Since the gear shaft 1 5 is meshed with the tooth plate 6, the tooth plate 6 and the cylinder 1 can be driven to move in the height direction. At the same time, the V The limit blocks 8 at both ends of the rod 7 slide along the limit grooves 9 provided on the tooth plate 6. When the cylinder 1 is lifted or lowered, the transverse plate 18 slides along the longitudinal plate 17. Since the gear shaft 3 19 is meshed with the concave tooth portion 20, the gear shaft 3 19 can be driven to rotate along the transverse plate 18. The torsion spring 23 is elastically deformed by force. When the gear shaft 3 19 rotates, it also pushes the L-shaped rod 21 and the suspension bracket 24 to slide in the horizontal direction along the transverse plate 18. When the gear shaft 3 19 moves to the gap between the adjacent concave tooth portions 20, the torsion spring 23 gradually returns to its original state, so that the The L-shaped rod 21 and the detection rod 25 move in opposite directions, and the above process is repeated. The detection rod 25 can be used to detect the rising sample. After the detection, the sample is discharged from the outlet 3. When the gear shaft 3 19 rotates, it drives the pulley 3 26 to rotate synchronously. The pulley 3 26 also drives the pulley 4 28 and the crushing knife 29 to rotate through the synchronous belt 2 27. The crushing knife 29 crushes the sample discharged from the outlet 3. The crushed sample moves along the blanking plate 30 and enters the spiral feeding cylinder along the feed port 32 when it moves to the end. 31, and moves along the spiral feeding cylinder 31 and is finally discharged from the outlet cylinder 34, and the movement of the sample is accelerated by the moving L-shaped rod 21; the depth adjustment mechanism 100 of the surveyor can not only stably adjust the depth during surveying, but also when the sample moves along the cylinder 1, the dynamic detection mechanism 200 can push the detection rod 25 to reciprocate along the cylinder 1 to perform multi-component detection on the sample. After the detection, the sample can be automatically crushed and the crushed sample can be collected to facilitate the subsequent accelerated discharge of the sample.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
