Description

Technical Field

[0001] The present invention relates to the technical field of surveying equipment, and more specifically, to a device for shallow soft soil exploration and sampling. Background Art

[0002] Soft soil is a general term for a type of soil, not referring to a specific kind of soil. In engineering, soft soil is often subdivided into soft cohesive soil, silt soil, silt, peat soil, peat, etc. It has characteristics such as high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex layered distribution of soil layers, and significant differences in physical and mechanical properties between layers.

[0003] Soft soil geological exploration is an important task in soft foundation reinforcement projects and dredged fill soil improvement projects. Before the project starts, it is often necessary to first sample and analyze the properties of soft soil geology to ensure the construction quality. Most of the existing samplers have an open bottom, and the soil sampling is achieved through the pressure difference inside and outside the sampler. However, the soft soil is relatively soft, resulting in the soil sample inside the sampler slipping from the open end when the sampler is pulled out of the ground, affecting the efficiency of soft soil sampling. Moreover, some samplers cannot seal the soft soil sample during the sampling process, resulting in the soft soil sample being mixed with soils at different depths during the up and down movement of the sampler, thus affecting the detection accuracy of the soft soil sample in the later stage.

[0004] In summary, the inventor provides a device for shallow soft soil exploration and sampling. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0027] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0028] As Figure 1 shown in FIG. -8, the present invention provides a soft soil shallow layer exploration and sampling device, including: a base 1 and a C-shaped bracket 2, the bottom of the C-shaped bracket 2 is fixedly connected to the top of the base 1, both sides of the inner wall of the C-shaped bracket 2 are provided with chutes 3, sliders 4 are slidably installed in the chutes 3, an electric cylinder 5 is installed above the sliders 4 inside the C-shaped bracket 2, the output end of the electric cylinder 5 is fixedly connected to the top of the slider 4, a drilling and sampling assembly 6 is installed at the bottom of the slider 4, an isolation sample support assembly 7 is arranged on one side of the C-shaped bracket 2, a battery pack 8 is installed above the electric cylinder 5 inside the C-shaped bracket 2, and a left handle 9 and a right handle 10 are symmetrically installed on both sides of the C-shaped bracket 2.

[0029] Among them, the drilling and sampling assembly 6 includes a cylinder 61, the top of the cylinder 61 is fixedly connected to the bottom of the slider 4, a sector-shaped notch 62 is arranged on the cylinder 61, a driving motor 63 is fixedly installed at the top of the inner wall of the cylinder 61, the driving motor 63 is connected to a rotating shaft 64 through a coupling, the other end of the rotating shaft 64 is rotatably connected to the bottom of the inner wall of the cylinder 61, a plurality of sampling cutters 65 are fixedly connected to the rotating shaft 64, a plurality of through grooves 66 are opened on the inner wall of the sector-shaped notch 62, and the sizes of the plurality of through grooves 66 are adapted to the sampling cutters 65.

[0030] It should be noted that: the bottom end of the cylinder 61 is set to be conical, which is convenient for the drilling and sampling assembly 6 to enter the soil. By arranging a plurality of sampling cutters 65 at different positions and heights, soil at different depths can be sampled at one time during the sampling process, which is convenient for the staff to conduct comparative tests.

[0031] It should be noted that: as Figure 4 、 5 、6 shows, the inner walls of the sector-shaped notch 62 are respectively denoted as a, b, and c, the cross-sectional shape of the sampling cutter 65 is trapezoidal, and one side is provided with an open mouth. When the sampling cutter 65 rotates around the rotating shaft 64, one end of the sampling cutter 65 passes through the through groove 66, and the side with the open mouth slides along the inner wall b of the sector-shaped notch 62. When one end of the sampling cutter 65 abuts against the inner wall c of the sector-shaped notch 62, a sealed accommodation cavity is formed between the sector-shaped notch 62 and the sampling cutter 65.

[0032] Among them, two pairs of connecting plates 11 are fixedly connected to both sides of the C-shaped bracket 2, and the two pairs of connecting plates 11 are respectively fixedly connected to the top and bottom of the electric cylinder 5 through bolts.

[0033] It should be noted that the electric cylinder 5 is installed on the U-shaped bracket 2 through two pairs of connecting plates 11. The two pairs of connecting plates 11 can prevent the U-shaped bracket 2 from deforming during long-term use and at the same time provide the necessary installation conditions for the electric cylinder 5.

[0034] Among them, the isolation sample support assembly 7 includes a mounting plate 71 fixedly connected to the side wall of the U-shaped bracket 2. A shaft rod 72 is rotatably connected to the mounting plate 71. A gear 73 is fixedly connected to the top of the shaft rod 72. A plurality of tray mechanisms 74 are fixedly connected to the shaft rod 72. An electric telescopic rod 75 is fixedly installed on the side wall of the U-shaped bracket 2. A rack 76 is fixedly connected to the output end of the electric telescopic rod 75. The rack 76 meshes with the gear 73.

[0035] Among them, the tray mechanism 74 includes a base 741 fixedly connected to the shaft rod 72. An installation cavity 742 is opened at the top of the base 741. A containing tray 743 is slidably installed in the installation cavity 742. A mounting block 744 is fixedly connected to the side wall of the containing tray 743. A pin hole 745 is opened on the side wall of the mounting block 744. A rectangular block 746 is fixedly installed on one side of the base 741. A pin 747 is slidably installed in the rectangular block 746. One end of the pin 747 extends into the pin hole 745. The other end of the pin 747 is fixedly connected to a spring 748. The other end of the spring 748 is fixedly connected to one side of the inner wall of the rectangular block 746. An opening 749 is opened on the side wall of the rectangular block 746. A dial 7450 is slidably installed in the opening 749. The other end of the dial 7450 is fixedly connected to the side wall of the pin 747.

[0036] It should be noted that when the containing tray 743 is installed, the dial 7450 needs to be pushed first to make the pin 747 slide in the rectangular block 746 and compress the spring 748. After the pin 747 is completely retracted into the rectangular block 746, the containing tray 743 is inserted into the installation cavity 742, and then the dial 7450 is released. At this time, the compressed state of the spring 748 is released, and the elastic potential energy of the spring 748 is released to push the pin 747 to move in the rectangular block 746 towards the pin hole 745, so that the front end of the pin 747 is inserted into the pin hole 745, thus completing the installation of the containing tray 743 and the base 741.

[0037] Among them, a charging port 81 and a power display 82 are opened on one side of the battery pack 8. The battery pack 8 is electrically connected to the electric cylinder 5, the drive motor 63, and the electric telescopic rod 75 respectively.

[0038] Among them, a switch one 91 is arranged on the left handle 9, a switch two 101 is arranged on the right handle 10, and a switch three 21 is arranged at a position on the side wall of the U-shaped bracket 2 close to the left handle 9.

[0039] It should be noted that switch one 91, switch two 101 and switch three 21 are respectively used to control the start and stop of the electric cylinder 5, the drive motor 63 and the electric telescopic rod 75. By arranging switch one 91, switch two 101 and switch three 21 in different positions, accidental touches during use can be prevented.

[0040] Among them, a number of cone spikes 12 are fixedly connected to the bottom of the base 1. By inserting the cone spikes 12 into the ground, the grip of the base 1 is improved to prevent the equipment from shaking during use and to avoid deviation of the drilling sampling component 6 during movement, thereby affecting the sampling effect.

[0041] Example:

[0042] like Figure 1As shown in Figure 8, in this embodiment, the device is first placed horizontally on the soft soil to be sampled, and the staff holds the left handle 9 and the right handle 10 with both hands respectively. The staff presses down a number of cone spikes 12 fixed at the bottom of the base 1 into the ground. At the same time, the staff stands on the pedal 13, and the device is placed horizontally more stably by its own weight. Then the staff presses the switch 191 on the left handle 9 to start the electric cylinder 5, and the electric cylinder 5 pushes the slide block 4 to move along the slide groove 3 toward the ground. The slide block 4 moves and pushes the drilling sampling assembly 6 into the soil. At this time, the fan-shaped gap 62 on the column 61 is filled with soil, and the staff presses the switch 2 101 to start the driving The driving motor 63 rotates the rotating shaft 64, and the rotating shaft 64 drives the sampling cutter 65 to rotate. The sampling cutter 65 rotates with the rotating shaft 64 as the center of the circle. The sampling cutter 65 passes through the through groove 66 and rotates in contact with the inner wall of the fan-shaped notch 62 to cut the soil. When one end of the sampling cutter 65 contacts the side wall of the fan-shaped notch 62, the driving motor 63 is turned off. At this time, a sealed accommodating chamber is formed between the sampling cutter 65 and the inner wall of the fan-shaped notch 62, thereby storing the soil sample inside. Then the staff presses the switch 1 91 again to make the electric cylinder 5 drive the drilling sampling assembly 6 out of the soil and reset it to the original position of the device. Then, the staff presses the switch 3 21 to start the electric The electric telescopic rod 75 pushes the rack 76 to move, and the rack 76 moves to drive the gear 73 meshing with it to rotate. The rotation of the gear 73 drives the shaft 72 to rotate, thereby driving the multiple tray mechanisms 74 fixedly connected to the shaft 72 to rotate, so that one side of the multiple tray mechanisms 74 fits the inner wall of the fan-shaped notch 62 and is located under the through slot 66 in sequence. After the tray mechanism 74 is stable, the staff presses the switch 101 again to start the drive motor 63, so that the rotating shaft 64 drives the sampling cutter 65 to reverse with the rotating shaft 64 as the center. At this time, the part of the sampling cutter 65 exposed outside the column 61 passes through the through slot 66 and enters the inside of the column 61. The soil sample in the sealed cavity formed by the middle sampling cutter 65 and the inner wall of the fan-shaped notch 62 flows out from one end of the sampling cutter 65 under the pressure of the inner wall of one side where the through groove 66 is set, and falls into the receiving tray 743 of the tray mechanism 74. When all the soil samples fall into the receiving tray 743, the staff pushes the paddle 7450 to one side, so that the pin 747 slides in the rectangular block 746 and compresses the spring 748. When the pin 747 is completely retracted into the rectangular block 746 and the front end of the pin 747 is out of the pin hole 745, the staff pulls the receiving tray 743 out of the installation cavity 742, and then properly places the soil samples collected in the receiving tray 743.

[0043] It should be noted that: in the initial state, one end of the sampling cutter 65 is located in the through groove 66 and is flush with the inner wall of the fan-shaped notch 62, so as to prevent the soil from entering the column 61 through the through groove 66 after the drilling sampling assembly 6 enters the soil.

[0044] After the sampling is completed, the staff checks whether the power needs to be replenished through the power display 82. If necessary, the charging port 81 next to the power display 82 is used to charge the device, thereby ensuring that there is sufficient power reserve for the next use of the device.

[0045] From the above, it can be seen that the device simultaneously samples positions at different depths in the soil through the drilling sampling component 6, thereby improving the sampling efficiency, and with the cooperation of the sampling cutter 65, the fan-shaped notch 62 and the through groove 66, the sampled soil is sealed and preserved to prevent the soil from mixing during the up and down process of the drilling sampling component 6, thereby affecting the detection results. In addition, through the cooperation of the isolation sample support component 7, multiple samples are isolated and collected through the tray 743 of the tray mechanism 74, thereby preventing the samples from coming out from one end of the sampling cutter 65 at the same time, and mixing between the samples when the samples fall, thereby affecting the detection accuracy of samples at different depths.

[0046] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
