Specific embodiments

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] Such as Figures 1 to 6As shown in the figure, it is a structural diagram of a geological survey instrument for geological engineering provided by an embodiment of the present invention, including a cylinder body 1, a fixing plate 4, a dynamic detection mechanism 200, a synchronous crushing mechanism 300, and an anti-blocking feeding mechanism 400. A drill rod 2 is rotatably installed inside the cylinder body 1. The drill rod 2 is driven by a first motor arranged at the top end of the cylinder body 1. A discharge port 3 is also opened on the side surface of the top end of the cylinder body 1. The fixing plates 4 are symmetrically arranged on both sides of the cylinder body 1. A depth adjustment mechanism 100 is installed on the cylinder body 1 and the fixing plate 4. When the depth adjustment mechanism 100 works, it pushes the cylinder body 1 to move along the fixing plate 4 in the height direction. The dynamic detection mechanism 200 is arranged on the cylinder body 1 and the fixing plate 4. A plurality of detection rods 25 are installed at the free end of the dynamic detection mechanism 200. The detection rods 25 are slidably connected to the cylinder body 1. When the dynamic detection mechanism 200 rises and falls with the depth adjustment mechanism 100, it pushes the detection rods 25 to continuously embed into the cylinder body 1 for detection. The synchronous crushing mechanism 300 is installed on the cross plate 18 and the third gear shaft 19 in the dynamic detection mechanism 200. When the third gear shaft 19 rotates, it crushes the materials discharged from the discharge port 3. The anti-blocking feeding mechanism 400 is arranged outside the cylinder body 1. The anti-blocking feeding mechanism 400 rises and falls synchronously with the cylinder body 1, and automatically collects and exports the samples that fall after being crushed by the synchronous crushing mechanism 300 to the outside.

[0040] In an example of the present invention, a base plate 15 is hinged to the side surface of the fixing plate 4. The base plate 15 is arranged on a walking device. A telescopic member 16 is fixedly installed on the base plate 15. The free end of the telescopic member 16 is connected to the fixing plate 4. The telescopic member 16 is also electrically connected to an external controller 35, so as to adjust the inclination angles of the fixing plate 4 and the cylinder body 1 as needed before and after use, thereby realizing convenient storage and transportation work for the whole.

[0041] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present invention, the depth adjustment mechanism 100 includes a first gear shaft 5, a toothed plate 6, a V-shaped rod 7, a limit block 8, and a limit groove 9;

[0042] The first gear shaft 5 is rotatably installed on the fixing plate 4. The first gear shaft 5 meshes with the toothed plate 6 installed on the outside of the cylinder body 1. The first gear shaft 5 is driven by an external second motor.

[0043] The fixing plate 4 is fixedly installed with a V-shaped rod 7. Both ends of the V-shaped rod 7 are fixedly connected with limit blocks 8. The limit blocks 8 are slidably connected with the limit grooves 9 opened on the toothed plate 6, so as to ensure the stable movement of the cylinder body 1.

[0044] 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.

[0045] 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;

[0046] 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;

[0047] 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 .

[0048] 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.

[0049] 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;

[0050] 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;

[0051] 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;

[0052] The end of the gear shaft 3 19 is also equipped with a torsion spring 23 connected to the horizontal plate 18;

[0053] 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.

[0054] 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.

[0055] 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;

[0056] 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;

[0057] 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.

[0058] 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;

[0059] 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.

[0060] like Figure 1 As shown in FIG. 1 , 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 ;

[0061] The blanking plate 30 is arranged outside the cylinder body 1 and is located at the bottom end of the discharge port 3;

[0062] The cylinder body 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 feeding port 32, and the feeding port 32 receives the samples dropped by the blanking plate 30;

[0063] The end of the spiral feeding cylinder 31 is installed with a discharge cylinder 34 for discharging the crushed samples outwards.

[0064] In an example of the present invention, the crushed samples move along the blanking plate 30, enter the spiral feeding cylinder 31 along the feeding port 32 when reaching the end, and move along the spiral feeding cylinder 31 and finally discharge from the discharge cylinder 34. At the same time, the reciprocating L-shaped rod 21 also contacts the inner wall of the spiral feeding cylinder 31 under working conditions, so as to accelerate the discharge of the samples outwards and avoid blockage.

[0065] In summary, during the survey, the motor at the top of the cylinder 1 drives the drill rod 2 to rotate inside the cylinder 1 to achieve the drilling operation. When the second motor works, it drives the first gear shaft 5 to rotate along the fixed plate 4, and the corresponding first pulley 12 rotates synchronously. The first pulley 12 also drives the second pulley and the second gear shaft 14 to rotate along the vertical rod 11 through the first synchronous belt 13. The two second gear shafts 14 are meshed, enabling the first gear shafts 5 at both ends to rotate in opposite directions. Since the first gear shaft 5 is meshed with the toothed plate 6, it can drive the toothed plate 6 and the cylinder 1 to move in the height direction. At the same time, the limit blocks 8 at both ends of the V-shaped rod 7 slide along the limit grooves 9 opened on the toothed plate 6. When the cylinder 1 rises and falls, the cross plate 18 slides along the longitudinal plate 17. Since the third gear shaft 19 is meshed with the concave tooth part 20, it can drive the third gear shaft 19 to rotate along the cross plate 18. The torsion spring 23 undergoes elastic deformation under force. When the third gear shaft 19 rotates, it also pushes the L-shaped rod 21 and the suspension bracket 24 to slide horizontally along the cross plate 18. And when the third gear shaft 19 moves to the gap between adjacent concave tooth parts 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. By repeating the above process, the arranged detection rod 25 can be used to detect the ascending sample. After the detection is completed, the sample is discharged outward from the export port 3. When the third gear shaft 19 rotates, it drives the third pulley 26 to rotate synchronously. The third pulley 26 also drives the fourth pulley 28 and the crushing knife 29 to rotate through the second synchronous belt 27. The arranged crushing knife 29 crushes the sample exported from the export port 3. The crushed sample moves along the blanking plate 30 and enters the spiral feeding cylinder 31 along the feeding port 32 at the end, and then moves along the spiral feeding cylinder 31 and finally is discharged from the export cylinder 34. The movement of the sample is also accelerated under the action of the moving L-shaped rod 21. This survey instrument can not only stably adjust the depth during the survey through the arranged depth adjustment mechanism 100, but also, when the sample moves along the cylinder 1, the arranged dynamic detection mechanism 200 pushes the detection rod 25 to reciprocate along the cylinder 1 to perform multi-component detection on the sample. After the detection is completed, the sample can be automatically crushed, and the crushed sample can be collected to facilitate the subsequent acceleration of the sample to be discharged outward.
