Description

Technical Field

[0001] This application relates to the field of compaction testing equipment, and more particularly to a hole-taking device for testing compaction using the sand-filling method. Background Technology

[0002] The sand cone method is a commonly used field test method for determining the compaction degree of soil or road base materials. By filling the test hole with standard sand, the wet density and dry density of the material excavated from the test hole are indirectly measured. The results are compared with the maximum dry density obtained from the standard compaction test in the laboratory to evaluate the compaction quality. When implementing the sand cone method, a sampling device is required to take soil samples from the location to be tested.

[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: the drilling device generally uses a motor to drive a screw rod to rotate inside the casing to remove the soil in the casing area. When the motor drives the screw rod to rotate, it may tilt due to collision with the underground soil, causing the screw rod to move out of the casing area underground and bring out the soil beyond the casing area, affecting the accuracy of the sand filling method detection. Utility Model Content

[0004] This application provides a sampling device for testing compaction using the sand-filling method, which solves the problem of shaking that easily occurs when the auger rotates to sample soil in the prior art, and achieves the effect of limiting the auger to improve the accuracy of soil sampling.

[0005] This application provides a sampling device for testing compaction degree using the sand-filling method, including a base with a through groove in the middle, a protective sleeve on the top of the base, a drive motor on the top of the protective sleeve, a helical rod on the output shaft of the drive motor, and a support assembly on the top of the base. The support assembly includes: a mounting plate on the top of the protective sleeve, with the helical rod at the bottom of the mounting plate and the drive motor mounted on the top of the mounting plate; two support plates on opposite sides of the mounting plate, fixedly mounted on the top of the base, with the mounting plate slidably connected between the two support plates; and an inclined support plate on the outside of the support plates, inclinedly positioned between the base and the support plates.

[0006] Furthermore, a groove is provided in the middle of the inner side of each of the two support plates, and movable blocks are provided on both sides of the mounting plate. The two movable blocks are slidably connected to the inside of the two grooves respectively.

[0007] Furthermore, a guide rail is provided inside one of the grooves, and one of the movable blocks is sleeved and slidably connected to the outside of the guide rail.

[0008] Furthermore, the mounting plate has a marking on its front side, and the protective sleeve has a scale plate on its front side, with the marking located on the outside of the scale plate.

[0009] Furthermore, the two support plates are provided with a movable component, the movable component including: a lead screw, which is rotatably connected to the inside of the other lead screw, and the other movable block is sleeved and threadedly connected to the outside of the lead screw; a reduction motor, which is fixedly installed on the top of one of the support plates, and the output shaft of the reduction motor is fixedly connected to the lead screw.

[0010] Furthermore, a level is provided in the middle of the side of the base.

[0011] The technical solution provided in this application has at least the following technical effects or advantages:

[0012] The rotation of the lead screw drives the movable block connected to it to move the mounting plate up and down between the two support plates. When the threaded rod at the bottom of the mounting plate moves up and down, it can be limited by the guide rail and the two support plates. The inclined support plate supports the support plate, so that the threaded rod will not move arbitrarily during soil sampling, preventing the screw rod from tilting and moving out of the casing area, thus improving the accuracy of soil sampling and sand filling detection.

[0017] This application discloses a hole-taking device for detecting compaction degree using the sand-filling method. The mounting plate 31 moves up and down between two support plates 32, and the two movable blocks 34 move on the outside of the guide rail 36 and the lead screw 61, respectively. This allows the mounting plate 31 to limit the movement of the drive motor 40 and the screw rod 50, preventing the screw rod 50 from deviating when it moves down, which would affect the accuracy of the soil sampling.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Please refer to Figure 1 This embodiment provides a drilling device for testing compaction using the sand-filling method, including a base 10. A through groove 11 is formed in the middle of the base 10, and a movable iron plate is placed at the through groove 11 to block it after soil removal. A protective casing 20 is provided on the top of the base 10, and a drive motor 40 is installed on the top of the casing 20. A helical rod 50 is mounted on the output shaft of the drive motor 40, extending through the through groove 11 into the soil for drilling. A level 80 is installed in the middle of the side of the base 10. A support assembly 30 is provided on the top of the base 10, including a mounting plate 31, support plates 32, inclined support plates 33, movable blocks 34, markers 35, and guide rails 36. The mounting plate 31 is located on the top of the casing 20, and the helical rod 50 is located at the bottom of the mounting plate 31. The drive motor 40 is mounted on the top of the mounting plate 31, and the two support plates 32 are respectively mounted on the top of the casing 20. On both sides of the mounting plate 31, two support plates 32 are fixedly installed on the top of the base 10, and the mounting plate 31 is slidably connected between the two support plates 32. The base 10 is determined to be in a horizontal position by using a level 80 to perform the drilling operation. The casing 20 is placed at the location of the soil to be tested, enclosing the location of the soil to be tested. This also prevents the soil brought out by the screw rod 50 from leaking out of the casing 20 and mixing with the soil in other locations, causing damage to the soil sample. It can also reduce water evaporation, ensure the roundness of the hole, reduce the need for re-adjustment, and improve the accuracy of compaction testing. The two support plates 32 limit the movement of the mounting plate 31 on both sides, so that the downward movement of the mounting plate 31 driving the drive motor 40 and the screw rod 50 can be limited. This prevents the screw rod 50 from shaking due to contact with soil and gravel during drilling, which would cause the soil to be drilled out beyond the location of the soil to be tested, thus affecting the accuracy of the sand filling method test.

[0020] Please refer to Figure 1 and Figure 2An inclined support plate 33 is disposed on the outside of the support plate 32, and is obliquely disposed between the base 10 and the support plate 32. A groove 321 is provided in the middle of the inner side of both support plates 32. Two movable blocks 34 are respectively disposed on both sides of the mounting plate 31. The two movable blocks 34 are slidably connected to the inside of the two grooves 321. A guide rail 36 is disposed inside one of the grooves 321. One of the movable blocks 34 is sleeved and slidably connected to the outside of the guide rail 36. The two inclined support plates 33 support the outside of the support plate 32, so that the support plate 32 will not shake arbitrarily with the vibration of the mounting plate 31, ensuring the stability of the spiral rod 50 when drilling downward on the mounting plate 31. The movement of the movable block 34 on the guide rail 36 limits the downward movement of the mounting plate 31, ensuring that the spiral rod 50 will not tilt during drilling and exceed the detection area, thus improving the accuracy of the sand filling method detection.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 The mounting plate 31 has a mark 35 on its front side, and the sleeve 20 has a scale plate 70 on its front side. The mark 35 is located on the outside of the scale plate 70. Two support plates 32 are equipped with moving components 60, each including a lead screw 61 and a reduction motor 62. The lead screw 61 is rotatably connected to the inside of another lead screw 61, and another movable block 34 is fitted and threadedly connected to the outside of the lead screw 61. The reduction motor 62 is fixedly mounted on the top of one support plate 32, and the output shaft of the reduction motor 62 is fixedly connected to the lead screw 61. The rotation of the geared motor 62 drives the geared motor 62 to rotate inside the groove 321, which in turn drives the movable block 34, which is threadedly connected to it on the outside, to move up and down inside the groove 321. This causes the mounting plate 31 to drive the drive motor 40 and the screw rod 50 to move up and down, which can quickly complete the drilling work and improve drilling efficiency. By moving the mark 35 on the scale plate 70 as the mounting plate 31 moves, the height of the screw rod 50 inserted into the ground can be accurately determined according to the scale value of the mark 35 on the scale plate 70, making the hole depth more accurate when drilling and soil extraction.

[0022] The functional principle of this application can be explained through the following methods:

[0023] In use, level the land at the location to be measured, then place the base 10 and the protective sleeve 20 at the location to be measured. Observe the level 80 on the base 10 to ensure that the base 10 and the land to be measured are level. Start the reduction motor 62, so that the output shaft of the reduction motor 62 drives the lead screw 61 to rotate in the groove 321, thereby causing the movable block 34 threadedly connected to the lead screw 61 to slide up and down. Another movable block 34 slides up and down along the guide rail 36 in another groove 321. The guide rail 36 limits and guides the mounting plate 31, thereby causing the drive motor 40 and the screw rod 50 on the mounting plate 31 to slide up and down between the two support plates 32, driving... The bottom of the auger 50 passes through the through groove 11 to reach the ground position. At this time, the mark 35 on the mounting plate 31 reaches the scale plate 70 on the casing 20. The reduction motor 62 continues to drive the mounting plate 31 to move down, so that the auger 50 drills into the ground. The movement of the mark 35 on the scale plate 70 is observed, so that the auger 50 can accurately drill into the specified depth. The soil drilled out by the auger 50 can be stored inside the casing 20. The screw 61 is reversed, so that the auger 50 is taken out from the ground. The iron piece in the through groove 11 is moved to the through groove 11 and blocked. The soil extracted is stored in the casing 20 of the base 10, and then the subsequent compaction test is carried out.
