Description

Technical Field

[0001] This utility model relates to the field of geotechnical strength testing technology, specifically to a geological geotechnical exploration strength testing device. Background Technology

[0002] Geological exploration requires testing the strength of soil and rock. Soil and rock strength testing is a key step in engineering geological exploration, providing important data support for fields such as civil engineering, geological engineering, and mining engineering.

[0003] In existing technologies, when testing soil and rock, the soil and rock are first sampled, and then a uniaxial compressive load is applied to the sample to measure the compressive strength and deformation characteristics of the soil and rock. However, in order to test the maximum pressure that the blocky soil and rock can withstand, the blocky soil and rock needs to be crushed. During the process of applying pressure to the soil and rock, soil and rock fragments will be ejected outward, causing damage to the surrounding area. Moreover, the crushed soil and rock needs to be cleaned up manually, which is very inconvenient, increases labor costs and greatly reduces the efficiency of the test. Utility Model Content

The protective plate is pre-inserted into the slot so that the through-hole corresponds to the pressure block. During the subsequent operation of the motor, the pressure block crushes the rock and soil, producing scattered rock and soil debris. The protective plate prevents the rock and soil debris from overflowing through the discharge port and causing injury to the workers. The pressure sensor receives the maximum pressure value at the moment of crushing, which is the data for the rock and soil strength test. After obtaining the test data, the motor reverses, driving the protective plate and pressure block back to the initial position. The workers can then remove and clean the discharge bin for future reuse. Therefore, this geological rock and soil exploration strength testing device solves the problem mentioned in the background art of existing technologies where rock and soil debris bounces outwards, causing damage to the surrounding area and being difficult to clean.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figures 1 to 5 A geological and soil exploration strength testing device includes a test platform 1 and a discharge bin 2. The discharge bin 2 has a discharge port 3. The test platform 1 has a groove 4 that matches the discharge bin 2. The discharge bin 2 and the inner wall of the groove 4 are slidably fitted. It also includes a fixed base 5, a testing mechanism and a protective component. The bottom end of the fixed base 5 is fixedly connected to the top end of the test platform 1. The fixed base 5 has a moving groove 6.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the test mechanism is set directly above the discharge hopper 2 via a lifting mechanism for testing the soil and rock inside the discharge hopper 2. The lifting mechanism includes a motor 7, a lifting plate 8, and a first screw 9. The motor 7 is mounted on the top of the fixed base 5. One end of the lifting plate 8 is slidably engaged with the inner wall of the moving groove 6. The two ends of the first screw 9 are rotatably connected to the inner top wall and inner bottom wall of the moving groove 6, respectively. The first screw 9 passes through one end of the lifting plate 8 and is threadedly connected to the lifting plate 8. By starting the motor 7, the output end of the motor 7 rotates, driving the first screw 9 to rotate. The rotation of the first screw 9 drives the lifting plate 8 to move.

[0026] The testing mechanism includes a test frame 10, a pressure sensor 11, a spring 12, a connecting plate 13, and a pressure block 14. One end of the test frame 10 is fixedly connected to the other end of the lifting plate 8. The pressure sensor 11 is installed on the inner top wall of the test frame 10. One end of the spring 12 is fixedly connected to the bottom end of the pressure sensor 11. One end of the connecting plate 13 is fixedly connected to the other end of the spring 12. The connecting plate 13 slides against the inner wall of the test frame 10. A through groove is provided at the bottom end of the test frame 10 to cooperate with the pressure block 14. One end of the pressure block 14 passes through the through groove and is fixedly connected to the other end of the connecting plate 13. The motor 7 drives the lifting plate 8 to move, thereby moving the test frame 10. When the test frame 10 moves, it moves the pressure sensor 11, spring 12, connecting plate 13 and pressure block 14 downward together, and places the soil and rock to be tested in the discharge bin 2. When the other end of the pressure block 14 squeezes the soil and rock, the connecting plate 13 squeezes the spring 12. The spring 12 contracts and exerts pressure on the pressure sensor 11. The spring 12 can play a buffering role to prevent the soil and rock from being too hard and damaging the pressure block 14. The pressure received by the pressure sensor 11 increases and increases. When the soil and rock break, the pressure value received by the pressure sensor 11 is the largest, and then it gradually decreases. The maximum value is the data of the soil and rock strength test.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the protective assembly is installed on the fixed base 5 and the test bench 1 to seal the discharge port 3. The protective assembly includes a protective plate 15, a support base 17, two connecting springs 19, a moving plate 20, a limiting rod 21, a limiting block 22, and a driving component. A slot 16 is provided on the outer wall of the discharge bin 2 to mate with the protective plate 15. The protective plate 15 slides against the inner wall of the slot 16. The bottom end of the support base 17 is fixedly connected to the top end of the test bench 1. Figure 5As shown, the support base 17 has a slot 18 that mates with the protective plate 15. The inner bottom wall of the slot 18 and the inner bottom wall of the slot 16 are on the same horizontal plane. Both the slot 18 and the slot 16 support the protective plate 15. The protective plate 15 slides in contact with the inner wall of the slot 18. One end of the connecting spring 19 is fixedly connected to one end of the protective plate 15. The other ends of both connecting springs 19 are fixedly connected to one end of the moving plate 20. The connecting spring 19 is sleeved on the outer wall of the limiting rod 21. One end of the limiting rod 21 is fixedly connected to one end of the protective plate 15, and the other end passes through the moving plate 20. One end of the limiting block 22 is fixedly connected to the other end of the limiting rod 21. The driving component is set on the fixed base 5 and is used to drive the moving plate 20 to move horizontally. The driving component includes a connecting rod 23, an active bevel gear 24, a driven bevel gear 25, and a second screw 26. One end of the connecting rod 23 is coaxially connected to the bottom end of the first screw 9. The fixed base 5 has a cavity. One end of the bevel tooth 24 is rotatably connected to the inner top wall of the cavity and coaxially connected to the other end of the connecting rod 23. One end of the driven bevel tooth 25 is rotatably connected to the inner side wall of the cavity. The driven bevel tooth 25 meshes with the active bevel tooth 24. One end of the second screw 26 is coaxially fixedly connected to one end of the driven bevel tooth 25. The other end of the second screw 26 is rotatably connected to one end of the support base 17, passes through the moving plate 20, and is threadedly connected to the moving plate 20. The motor 7 drives the first screw 9 to rotate. The first screw 9 drives the connecting rod 23 to rotate. The connecting rod 23 drives the active bevel tooth 24 to rotate. The active bevel tooth 24 drives the driven bevel tooth 25 to rotate. The driven bevel tooth 25 drives the second screw 26 to rotate. The rotation of the second screw 26 drives the moving plate 20 to move toward the discharge bin 2. The moving plate 20 slightly squeezes the connecting spring 19 and pushes the connecting spring 19 to move. The connecting spring 19 pushes the protective plate 15 to move along the inner wall of the slot 18 and insert it into the slot 16.

[0028] It should be added that this device cannot be used to test all sizes of rock and soil. The rock and soil block to be tested is placed in the feeding bin 2. The motor 7 drives the first screw 9 to rotate, which drives the top lifting plate 8 from the moving slot 6 to move downward. At the same time, it indirectly drives the moving plate 20 to move towards the feeding bin 2. The moving plate 20 drives the protective plate 15 to move towards the slot 16. During the operation of the motor 7, after the moving plate 20 is inserted into the slot 16, one end of the moving plate 20 is pressed against the inner wall of the slot 16. The rock and soil are below the protective plate 15 and are very close to it. However, at this time, the bottom end of the pressure block 14 and the top end of the protective plate 15 are on the same horizontal line. With the continued drive of the motor 7, the moving plate 20 continues to move and squeeze the connecting spring 19. The connecting spring 19 continuously contracts. At the same time, the pressure block 14 moves downward through the through hole 27 to squeeze and break the rock and soil.

[0029] It should be further explained that the motor 7 in this embodiment is a conventional device known to those skilled in the art and available on the market. The model can be selected or customized according to actual needs. In this patent, we only use it without improving its structure and function. Its setting method, installation method and electrical connection method can be debugged and operated by those skilled in the art according to the requirements of its instruction manual, and will not be described in detail here. The motor 7 is equipped with a matching control switch. The installation position of the control switch is selected according to the actual use requirements to facilitate the operation and control by the operator. At the same time, the motor 7 needs to be connected to the forward and reverse circuit before use for forward and reverse operation. As for the forward and reverse use of the motor 7, according to the patent disclosed by patent number CN109889124A, the forward and reverse operation of the motor 7 is a well-known technology to those skilled in the art, and the technology is very mature and can be implemented.

[0030] Working Principle: Before conducting strength tests on soil and rock, the bottom of the cleaned material hopper 2 is inserted into the groove 4. Blocky soil and rock are then placed into the material hopper 2. The motor 7 is started, and its output rotates, driving the first screw 9 to rotate. The first screw 9 rotates, moving the lifting plate 8 and simultaneously the connecting rod 23. The lifting plate 8 moves the test frame 10, which in turn moves the pressure sensor 11, spring 12, connecting plate 13, and pressure block 14 downwards. Meanwhile, the connecting rod 23 rotates, driving the active bevel gear 24 to rotate. The active bevel gear 24 drives the driven bevel gear 25 to rotate, which in turn drives the second screw 26 to rotate. The second screw 26 rotates, causing the moving plate 20 to move towards the material hopper 2. The moving plate 20 slightly compresses the connecting spring 19 and pushes the connecting rod 24 downwards. The connecting spring 19 moves, pushing the protective plate 15 along the inner wall of the slot 18 and inserting it into the slot 16. At this time, the pressure block 14 corresponds to the through hole 27. When the pressure block 14 squeezes the soil and rock during subsequent movement, the connecting plate 13 squeezes the spring 12. The spring 12 contracts and exerts pressure on the pressure sensor 11. The pressure received by the pressure sensor 11 increases. When the soil and rock break, splashing soil and rock debris is generated. The protective plate 15 blocks the debris, preventing it from overflowing through the discharge port 3 and causing injury to the workers. The pressure value received by the pressure sensor 11 is at its maximum and then gradually decreases. The maximum value is the data of the soil and rock strength test. After obtaining the test data, the motor 7 reverses and drives the protective plate 15 and the pressure block 14 back to the initial position. The workers can then remove the discharge hopper 2 and clean it.
