Description

Technical Field

[0001] The invention relates to the technical field of land surveying and mapping, and in particular to a soil layer depth measuring device. Background Art

[0002] Soil layer depth measurement is a type of land surveying work. In order to ensure the construction quality of the project, soil layer depth measurement is an indispensable task before construction. By measuring the soil layer depth, the construction depth of industrial and agricultural construction and various civil engineering construction can be roughly determined to prevent the construction depth from being too deep during the project construction, damaging the groundwater system and causing certain pollution to the environment. Corresponding hydrological works can be built, and more accurate soil layer depth measurement can improve the quality of project construction and speed up the progress of project construction.

[0003] Most soil depth measuring devices are equipped with a lifting plate, scale lines, and a pointer corresponding to the scale lines on one side of the lifting plate. A drill rod is rotatably arranged at the lower end of the lifting plate. During the rotation of the drill rod, the lifting plate moves downward to drill into the soil layer. The pointer and the scale lines cooperate with each other to indicate the depth of the drill rod drilling into the soil layer, which is beneficial for the operator to observe the depth of the drill rod drilling into the soil layer in real time. However, when the drill rod moves downward to drill into the soil layer, the threads on the surface of the drill rod will discharge the soil outward and disperse it around the borehole. After the soil layer depth measurement is completed, the drill rod will be taken out of the soil layer, leaving a deep hole on the surface of the soil layer, destroying the original surface environment. The staff will need to manually fill the deep hole later. When backfilling manually, the soil needs to be backfilled slowly bit by bit. Faster backfilling can easily cause the borehole port to be blocked, resulting in the borehole being hollow, and the operation is more laborious. Summary of the invention

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As shown in FIGS. 1-8, a soil layer depth measuring device includes a base 1 and a housing 2 provided at the upper end of the base 1. A slide plate 8 is slidably provided inside the housing 2. A drill rod 10 is rotatably provided at the lower end of the slide plate 8. A first motor 9 for driving the drill rod 10 to rotate is provided at the upper end of the slide plate 8. Two slide blocks 11 are symmetrically provided on the outer surface of the slide plate 8. Guide grooves 4 for the slide blocks 11 to slide are provided on the side wall of the housing 2. A pointer 12 is provided on one side of the two slide blocks 11. Scale lines 5 cooperating with the pointer 12 are respectively provided on the outer surface of the housing 2. A drill hole cooperating with the drill rod 10 is provided in the base 1. A backfill assembly for backfilling the soil drilled out by the drill rod 10 is provided at the upper end of the base 1. A positioning assembly for fixing the slide plate 8 is provided outside the housing 2;

[0035] The backfill assembly includes a hollow tube 7 and a soil collecting bucket 6 fixed to the upper end of the base 1. The hollow tube 7, the soil collecting bucket 6 and the drill rod 10 are located on the same axis. The inner diameter of the hollow tube 7 is larger than the inner diameter of the drill rod 10. The outer surface of the hollow tube 7 is in close contact with the inner wall of the borehole. The upper end of the outer side of the hollow tube 7 is symmetrically provided with sliding rods 22 through connecting rods 29. The slide plate 8 is provided with a vertical slide groove 21 that matches the sliding rod 22. A connecting plate 24 is fixedly provided on the outer side of one of the sliding rods 22. The slide plate 8 is provided with a notch groove 23 that matches the connecting plate 24. A mounting shell 14 is fixedly provided on the outer side of the shell 2. A second motor 27 is provided on the outer side of the mounting shell 14. The second motor The rotating shaft 28 of the machine 27 passes through the shell 2 and is provided with a turntable 25. The surface of the turntable 25 is provided with a protrusion 26. The surface of the connecting plate 24 is provided with a transverse groove 31 that cooperates with the protrusion 26. When the turntable 25 rotates, the connecting plate 24 is driven to move back and forth up and down under the cooperation of the protrusion 26 and the transverse groove 31, and then the hollow tube 7 is driven to move back and forth up and down. When the hollow tube 7 moves upward, the lower end of the soil collecting bucket 6 will be opened, and then the soil in the soil collecting bucket 6 will flow downward for backfilling. When the hollow tube 7 moves downward, the lower end of the soil collecting bucket 6 will be closed, thereby achieving the effect of backfilling the soil little by little and intermittently.

[0036] Furthermore, a rotating ring 35 is provided on the outer side of the hollow tube 7 for rotation, and a gear ring 34 is provided on the inner wall of the rotating ring 35. Two pressure plates 17 are provided at the lower end of the hollow tube 7 for symmetrical rotation, and gears 32 matching the gear ring 34 are provided on the upper ends of the rotating shafts of the two pressure plates 17, respectively, and the rotating shaft sleeves of the two pressure plates 17 are provided with a first torsion spring. A winding roller 33 is provided for rotation on one side of the upper end of the soil collecting bucket 6, and a second torsion spring is provided on the rotating shaft sleeve of the winding roller 33. The stiffness coefficient of the first torsion spring is greater than the stiffness coefficient of the second torsion spring. A pull rope 18 is fixedly wound around the outer surface of the winding roller 33, and the other end of the pull rope 18 is fixedly wound around the outer surface of the rotating ring 35. By setting the pressure plate 17, during the upward movement of the hollow tube 7, the rotating ring 35 will be driven to move upward first. At this time, the pull rope 18 is stretched under force, and the winding roller 33 is released during this process. When the pull rope 18 wound around the winding roller 33 is bent and released, the hollow tube 7 is The lower end of the tube 7 is in the soil collecting bucket 6. The continued upward movement of the hollow tube 7 will cause the rotating ring 35 to deflect and release the stretching. Under the cooperation of the ring gear 34 and the gear 32, the two pressure plates 17 are deflected. When the hollow tube 7 moves downward, the rotating ring 35 is first deflected and reset to reel in the pull rope 18. Under the cooperation of the ring gear 34 and the gear 32, the two pressure plates 17 are deflected and reset to be flush with the surface of the hollow tube 7. Then the hollow tube 7 continues to move downward, which will cause the winding roller 33 to rotate to reel in the pull rope 18. As the hollow tube 7 continues to move downward again, the winding roller 33 and the rotating ring 35 will release the pull rope 18 in turn, and the two pressure plates 17 will also be deflected again. At this time, after the two pressure plates 17 are deflected, they are directly above the drill hole. As the hollow tube 7 moves downward synchronously, the backfill soil is pressed to make the backfill more substantial.

[0037] Furthermore, the positioning component includes a U-shaped restraint rod 15 slidably clamped outside the housing 2 and an operating rod 16 fixedly arranged at the upper end of the U-shaped restraint rod 15. The mounting shell 14 is provided with a through slot for the sliding of the U-shaped restraint rod 15. The outer surface of the U-shaped restraint rod 15 is connected to the inner wall of the mounting shell 14 through a spring 20. The outer surfaces of the two sliders 11 are provided with clamping slots 19 that cooperate with the two ends of the U-shaped restraint rod 15. When the ends of the U-shaped restraint rod 15 are clamped into the clamping slots 19, the sliding of the sliders 11 is positioned, thereby ensuring the overall stability of the slide plate 8 and the drill rod 10. The staff does not need to keep lifting it all the time, which is relatively labor-saving.

[0038] Furthermore, the two pressing plates 17 are arc-shaped. The inner diameters of the two pressing plates 17 are the same as the inner diameter of the hollow tube 7, and the outer diameters of the two pressing plates 17 are the same as the outer diameter of the hollow tube 7.

[0039] Furthermore, a shielding ring 30 is sleeved outside the hollow tube 7. The upper surface of the shielding ring 30 is inclined downward. The shielding ring 30 is located above the rotating ring 35, so that the soil discharged upward during the operation of the drill rod 10 passes through the shielding ring 30 and is diverted into the soil collecting hopper 6, avoiding the influence of the soil entering the rotating connection of the rotating ring 35 on the rotation of the rotating ring 35.

[0040] Furthermore, a ground nail 3 is movably penetrated through the upper end of the base 1, facilitating the fixation of the base 1 at a specified position on the ground.

[0041] Furthermore, handles 13 are fixedly arranged at the opposite ends of the two sliders 11, facilitating the staff to hold the handles 13 for operation.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
