Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-5 , the present invention provides a technical solution: a soil sample hardness detection device for backfill materials, including an operation table 1. An L-shaped plate 2 is fixed on the top of the operation table 1. A cylinder 16 is fixedly penetrated through the top of the L-shaped plate 2. A pressure sensor 17 is fixed at the lower end of the cylinder 16. A pressing block 18 is fixed at the bottom of the pressure sensor 17. A computer 20 is arranged on the top of the operation table 1, and the computer 20 is electrically connected to the pressure sensor 17. The pressure generated by the pressure sensor 17 can be transmitted to the computer 20, and the computer 20 can record the pressure generated by the pressure sensor 17.

[0021] A discharging mechanism is arranged on the top of the operation table 1. The discharging mechanism includes an L-shaped support plate 5. The L-shaped support plate 5 is fixed on the front side of the operation table 1. A first rotating shaft 6 is rotatably installed between the L-shaped support plate 5 and the L-shaped plate 2 through a bearing. A movable block 4 is arranged on the outer side of the first rotating shaft 6. One side of the movable block 4 is fixedly connected to the rear side of the outer wall of the U-shaped baffle 3. The end of the first rotating shaft 6 penetrates through the inside of the L-shaped plate 2 and is fixed with a first bevel gear 7. A fixing plate 8 is fixed on the rear side of the L-shaped plate 2. A second rotating shaft 9 is rotatably installed between the fixing plates 8 through a bearing. A second bevel gear 10 is fixed on the outer wall of the second rotating shaft 9. The second bevel gear 10 is meshed with the first bevel gear 7. The end of the second rotating shaft 9 penetrates through the inside of the fixing plate 8 and is fixedly connected to the output end of the servo motor 11. The outer wall of the servo motor 11 is fixed on one side of the fixing plate 8 through a mounting plate. The movable block 4, the L-shaped support plate 5, the first rotating shaft 6, the first bevel gear 7, the fixing plate 8, and the second bevel gear 10 are all provided with two. And the movable block 4 is threadedly connected to the first rotating shaft 6. And the bottom of the U-shaped baffle 3 and the bottom of the front baffle 15 are in mutual contact with the top of the operation table 1. A collecting box 19 is arranged below the operation table 1. By starting the servo motor 11 to rotate forward or backward, the U-shaped baffle 3 can be moved forward or backward. When the U-shaped baffle 3 moves forward, the broken backfill soil samples inside the U-shaped baffle 3 and on the top of the operation table 1 can be pushed into the collecting box 19.

[0022] A top plate 12 is fixed on the inner top of the U-shaped baffle 3. A through hole 13 is opened in the middle of the top plate 12. The lower end of the cylinder 16 penetrates through the inside of the through hole 13. The setting of the top plate 12 prevents the broken backfill soil samples from flying out from the top of the U-shaped baffle 3. The setting of the through hole 13 enables the lower end of the cylinder 16 to pass through the inside of the through hole 13.

[0023] Both sides of the opening of the U-shaped baffle 3 are provided with limiting grooves 14. A front baffle 15 is slidably installed inside the limiting grooves 14. A through groove 21 is opened at the top of the front baffle 15, and the front baffle 15 is made of transparent acrylic board, so that the front baffle 15 can be taken out from the opening of the U-shaped baffle 3. Thus, backfill soil samples can be placed into the U-shaped baffle 3 from the opening of the U-shaped baffle 3, and the situation of the backfill soil samples inside the U-shaped baffle 3 can be seen through the front baffle 15.

[0024] Working principle: When using the soil sample hardness detection device for backfill materials, first pass the finger through the inside of the through groove 21, and then pull up the front baffle 15, so that both sides of the front baffle 15 move inside the limiting grooves 14 until the front baffle 15 is separated from the U-shaped baffle 3. Then, backfill soil samples are placed into the U-shaped baffle 3 from the opening of the U-shaped baffle 3, and then the front baffle 15 is installed back in place;

[0025] Then start the cylinder 16 to move downward. The lower end of the cylinder 16 drives the pressure sensor 17 and the pressing block 18 to move downward through the inside of the through hole 13. When the pressing block 18 breaks the backfill soil sample, the pressure sensor 17 detects the pressure and transmits it to the computer 20 to complete the hardness detection of the backfill soil sample;

[0026] When the broken backfill soil sample needs to be taken out, start the cylinder 16 to drive the pressure sensor 17 and the pressing block 18 to move upward away from the U-shaped baffle 3, and then take down the front baffle 15 from the opening of the U-shaped baffle 3. Then start the servo motor 11. At this time, the servo motor 11 drives the second rotating shaft 9 to rotate. The second rotating shaft 9 drives two first rotating shafts 6 to rotate through two second bevel gears 10 and two first bevel gears 7. Since the first rotating shaft 6 is threadedly connected to the movable block 4, the movable block 4 drives the U-shaped baffle 3 to move forward, pushing the broken backfill soil sample inside the U-shaped baffle 3 into the collection box 19. Then start the servo motor 11 to rotate in the reverse direction, so that the collection box 19 moves backward to reset.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
