Description

Technical Field

[0001] The utility model relates to the technical field of earthwork compaction degree detection auxiliary devices, in particular to a sand filling method rapid sampler. Background Art

[0002] In the process of backfill construction, compaction is an important indicator to measure the density and overall performance of backfill soil. The higher the compaction, the greater the density of the soil, and the better the engineering quality. In order to achieve this goal, the engineering community has adopted a variety of testing methods, including sand filling method, ring knife method and nuclear density meter method.

[0003] Among them, the sand filling method is a relatively direct method. It requires drilling a pit with a known diameter and depth at the construction site, then taking out the soil in the pit and weighing it. Then, fill the pit with clean and uniform fine sand and weigh it again. By comparing the weight of the soil sample taken out and the filling sand, combined with the volume of the pit, the compaction degree can be calculated.

[0004] In the prior art, when drilling a soil pit, a shovel or other tools is often used to dig the pit and dig out the soil in the pit little by little. The pit digging efficiency is low and manual operation is inconvenient, which makes the sand filling sampling time longer and affects the efficiency of sand filling sampling.

[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0036] See also Figures 1 to 5 As shown, the embodiment of the present application provides a rapid sampler for the sand filling method, including: a stabilizing plate 1, a pressing assembly 3 and a sampling assembly 7. The stabilizing plate 1 is also provided with threaded holes around it, and a screw-connected adjusting bolt 12 is arranged in the threaded hole. The adjusting bolt 12 is used to fix the stabilizing plate 1. At the same time, the stabilizing plate 1 can be leveled by adjusting the bolt 12 to make the pit digging more accurate. A center hole 11 is opened on the stabilizing plate 1, and a base 2 is arranged on the stabilizing plate 1. The base 2 is located on one side of the center hole 11. The pressing assembly 3 is arranged on the base 2. The pressing assembly 3 has a driving part and a connecting part 35. The driving part drives The movable connecting part 35 slides along its height direction, and the sampling assembly 7 is arranged on the connecting part 35. The sampling assembly 7 includes a cylinder 71 and a connecting shaft 72 connected to the outer top of the cylinder 71. The driving part drives the connecting part 35 to slide along its height direction to drive the cylinder 71 to penetrate the center hole 11 up and down. The sampling assembly 7 also includes a driving mechanism, which drives the cylinder 71 to rotate. The open end of the cylinder 71 can also be provided with an annular blade. When digging a pit, the contact area between the open end of the cylinder 71 and the ground soil sample can be reduced, so that the open end of the cylinder 71 can more easily enter the ground soil sample to complete the pit digging and sampling.

[0037] In the above scheme, the pressing component 3 and the sampling component 7 are set, and the connecting part 35 is connected to the sampling component 7, so that the pressing component 3 is started to drive the sampling component 7 to slide, and the cylinder 71 is driven to rotate by the set driving mechanism. When it is necessary to dig a hole, the pressing component 3 provides downward pressure for the sampling component 7, and the driving mechanism drives the cylinder 71 to rotate, so that the hole digging can be completed quickly. Compared with using a shovel or other tools to dig a hole, the time for sand filling and sampling is reduced, and the efficiency of hole digging and sand filling and sampling is improved.

[0038] In some possible implementations, see Figures 2 to 4As shown, the driving mechanism includes a driving rod 5 and a reduction motor 8. The end of the connecting shaft 72 away from the cylinder 71 is detachably connected to the driving rod 5. The driving rod 5 is driven by the reduction motor 8. The reduction motor 8 is arranged on the connecting part 35. The driving rod 5 is located on the side of the connecting part 35 away from the reduction motor 8, and the end of the driving rod 5 away from the reduction motor 8 is detachably connected to the connecting shaft 72. The output shaft of the reduction motor 8 passes through the connecting part 35 and is fixedly connected to the driving rod 5. When digging a pit for sampling, the reduction motor 8 is controlled to start, and the output shaft of the reduction motor 8 rotates to drive the driving rod 5 to rotate. The rotation of the driving rod 5 drives the cylinder 71 to rotate through the connecting shaft 72, so that the cylinder 71 is easier to insert into the ground soil sample.

[0039] In some possible implementations, see Figures 2 to 4 As shown, the driving part includes two vertical plates 31, and the two vertical plates 31 are symmetrically arranged on the base 2. A scale line is arranged on one side of any vertical plate 31 along its length direction, so as to control the depth of the cylinder 71 inserted into the ground. The depth of the earth pit (test hole) dug generally is 20 mm. The upper ends of the two vertical plates 31 are connected to the same top plate 32, and a rotatable screw rod 33 is arranged between the stabilizing disk 1 and the top plate 32. A driving assembly 37 is arranged on the top plate 32. The driving assembly 37 can be a driving motor. The output shaft of the driving assembly 37 passes through the top plate 32 and is fixedly connected to one end of the screw rod 33. A threaded connecting block 36 is sleeved on the screw rod 33. A sliding part 34 is connected to the connecting block 36 near the center hole 11. Both ends of the sliding part 34 in the length direction are slidably arranged on the two vertical plates 31 respectively. The sliding part 34 is connected to the connecting part 35 near the center hole 11, and the reduction motor 8 is arranged on the connecting part 35.

[0040] It should be noted that a slide groove is provided on one side of the vertical plate 31 close to the sliding part 34 along its length direction, and both ends of the sliding part 34 close to the slide groove have sliders that cooperate with the slide groove. The sliding part 34 is slidably arranged on the vertical plate 31 through the cooperation of the slider and the slide groove. A battery (not shown in the figure) is also arranged on the stabilizing plate 1, and the reduction motor 8 and the driving assembly 37 are electrically connected to the battery.

[0041] In the above scheme, when the driving component 37 is started, the output shaft of the driving component 37 rotates to drive the screw rod 33 to rotate. The rotation of the screw rod 33 drives the connecting block 36 to screw in cooperation with the sliding part 34, thereby driving the sliding part 34 to slide along the length direction of the vertical plate 31. The sliding part 34 slides through the connecting part 35 to drive the cylinder 71 to slide.

[0042] In some possible implementations, see Figures 1 to 3As shown, a stabilizing component 4 is also provided at the bottom of the connecting portion 35, and the stabilizing component 4 includes a stabilizing plate 41 and a plurality of stabilizing rods 42. The stabilizing plate 41 is sleeved on the driving rod 5, and the plurality of stabilizing rods 42 are evenly arranged along the circumferential direction of the driving rod 5. The two ends of the stabilizing rod 42 are respectively connected to the stabilizing plate 41 and the connecting portion 35, and the driving rod 5 is slidably connected to the stabilizing plate 41.

[0043] In the above solution, the plurality of stabilizing rods 42 and stabilizing plates 41 are provided to stably support the driving rod 5 , thereby preventing the driving rod 5 from being bent due to external impact, thereby protecting the driving rod 5 .

[0044] In some possible implementations, see Figure 5 As shown, a plurality of arc-shaped grooves 73 are provided on the inner wall of the cylinder 71, and a slidable sliding component is provided in each arc-shaped groove 73. The sliding component is connected to a soil-covering plate 74 at one end away from the arc-shaped groove 73. When the plurality of soil-covering plates 74 are located at the lowest end, the soil in the cylinder 71 is supported, and the soil-covering plate 74 and the arc-shaped groove 73 are cooperated with each other by friction.

[0045] It should be noted that during the soil sampling process, when the cylinder 71 slides out of the test hole, a large amount of soil samples in the cylinder 71 fall out of the cylinder 71. Therefore, when the cylinder 71 slides out of the test hole, it is necessary to shovel out the soil samples in the test hole using tools such as a shovel.

[0046] In the above scheme, when the cylinder 71 is inserted into the ground to the required depth, the soil covering plate 74 is controlled to slide along the arc groove 73 so that the soil covering plate 74 extends out of the cylinder 71. Multiple soil covering plates 74 are aggregated together to form an annular retaining plate to prevent the soil sample in the cylinder 71 from falling in large quantities during the process of the cylinder 71 sliding upward, thereby reducing the soil samples that have not been shoveled out in the test hole.

[0047] In some possible implementations, see Figure 5 As shown, each earth-covering plate 74 is hinged with a pressure rod 75, and a plurality of openings matching with the pressure rod 75 are provided on the top wall of the cylinder 71. The pressure rod 75 extends out of the corresponding opening at one end away from the earth-covering plate 74. The openings are provided to allow the pressure rod 75 to have a high degree of freedom, thereby preventing the pressure rod 75 from getting stuck with the inner wall of the cylinder 71, so that the earth-covering plate 74 can slide completely in the arc groove 73.

[0048] In some possible implementations, see Figure 4As shown, the sand filling method rapid sampler provided in the embodiment of the present application also includes a clamping assembly 6, which includes two arc-shaped clamping plates 61, one end of the two arc-shaped clamping plates 61 is hinged, and the other end is detachably connected by bolts and nuts, and the two arc-shaped clamping plates 61 are enclosed to form a cylindrical structure, and arc-shaped racks 62 are arranged along the arc length direction at both ends of the arc-shaped clamping plates 61, and tooth groups 9 are arranged on the connecting shaft 72 and the driving rod 5 along the circumferential direction thereof, and the two tooth groups 9 are respectively meshed with the two arc-shaped racks 62, and the arc-shaped clamping plates 61 have clamping parts at both ends in the height direction, and the two tooth groups 9 are located between the two clamping parts, and the two tooth groups 9 are respectively abutted against the two clamping parts.

[0049] It should be noted that in the sand filling method earthwork detection, different sand filling cylinders are often used, and the diameter of the sand filling cylinder is the same as the diameter of the test hole. Therefore, when using the sand filling method rapid sampler provided in the embodiment of the present application, it is necessary to change the model of the cylinder 71 according to different requirements.

[0050] In the above scheme, when replacing the cylinder 71, remove the bolts and nuts connecting the two arc-shaped clamping plates 61, open the two arc-shaped clamping plates 61, remove the cylinder 71, and place the other cylinders 71 into the two arc-shaped clamping plates 61, so that the tooth group 9 on the connecting shaft 72 at the upper end of the cylinder 71 engages with the arc-shaped rack 62 in the two arc-shaped clamping plates 61, and then close the two arc-shaped clamping plates 61 so that the clamping part of the arc-shaped clamping plates 61 rests on the tooth group 9, and finally fix the two arc-shaped clamping plates 61 with bolts and nuts.

[0051] A pressing plate is provided at one end of the pressing rod 75 away from the soil sealing plate 74 .

[0052] By setting up the pressing component 3 and the sampling component 7, and the connecting part 35 connecting the sampling component 7, the pressing component 3 is started to drive the sampling component 7 to slide, and at the same time, the cylinder 71 is driven to rotate by the set driving mechanism. When it is necessary to dig a hole, the pressing component 3 provides downward pressure for the sampling component 7, and at the same time, the driving mechanism drives the cylinder 71 to rotate, so that the hole digging can be completed quickly. Compared with using a shovel or other tools to dig a hole, the time for sand filling and sampling is reduced, and the efficiency of hole digging and sand filling and sampling is improved.

[0053] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
