Technical Field

[0001] The utility model provides a time-saving and labor-saving frozen soil sampling mechanism, belonging to the technical field of frozen soil sampling. Background Technique

[0002] Frozen soil refers to various rocks and soils with ice content below zero degree Celsius. In the fields of engineering technology construction and geological exploration, the research on frozen soil is of great significance. Before analyzing and researching frozen soil, it is often necessary to sample it.

[0003] Although the existing frozen soil sampling mechanisms can quickly take out the frozen soil located underground during sampling and can adjust the depth of the sampled frozen soil by controlling the depth of the sampling device inserted into the ground; however, the existing frozen soil sampling structures often directly sample a whole piece of frozen soil, which is inconvenient to stratify the sampled frozen soil sample at different heights during sampling and is not conducive to the sampling analysis of frozen soil at different depths by the staff, so it needs to be improved. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing frozen soil sampling device is inconvenient to stratify the frozen soil at different heights during sampling, which is not conducive to the analysis of frozen soil at different depths by the staff.

[0005] In order to solve the above problems, the technical solution proposed by the utility model is: a time-saving and labor-saving frozen soil sampling mechanism, including a support frame, and a hydraulic cylinder is arranged on the support frame; the working end of the hydraulic cylinder is fixedly connected with a support plate located inside the support frame, and two sampling cylinders are slidably arranged below the support plate; a chute is opened in the support plate, and a sliding structure fixedly connected with the sampling cylinder is slidably arranged in the chute; a sampling tip is fixedly connected to the bottom of the sampling cylinder; an installation groove is opened in the inner wall of the sampling cylinder, a partition plate is arranged in the installation groove, and the partition plate is fixedly connected with the sampling cylinder by screws; the two sampling cylinders are corresponding semi-cylindrical shapes, and the partition plate is a semi-cylindrical shape corresponding to the sampling cylinder.

[0006] As an improvement, the sliding structure includes sliders, there are two sliders, and the sliders are slidably arranged in the chute; a guiding groove is opened at the bottom of the support plate, and the sliders pass through the guiding groove and are fixedly connected with the sampling cylinder.

[0007] As an improvement, a motor is arranged on one side of the support plate, and a bidirectional lead screw rotatably arranged in the chute is fixedly connected to the output shaft of the motor; the two sliders are threadedly connected to the corresponding positions on the bidirectional lead screw; the chute and the sliders are corresponding cuboid structures, and the sliders are in mutual fit with the inner wall of the chute.

[0008] As an improvement, the installation grooves are evenly distributed up and down in the sampling cylinder, and countersunk holes are opened on the outer wall of the sampling cylinder, and the screws are located in the countersunk holes.

[0009] As an improvement, the sampling tip is semi-conical, and the bottom diameter of the sampling tip corresponds to the diameter of the sampling cylinder.

[0010] The beneficial effects of the utility model are as follows:

[0011] There are two sampling cylinders slidably arranged under the support plate. The bottom of the sampling cylinder is fixedly connected with a sampling tip. By driving the sampling cylinder to move downward by a hydraulic cylinder, and with the cooperation of the sampling tip, the insertion of the sampling cylinder can be made more time-saving and labor-saving. At the same time, after the sampling cylinder is inserted into the ground, the two sampling cylinders are driven to engage by a sliding structure, and sampling can be carried out quickly and conveniently. At the same time, since a partition is provided in the sampling cylinder, when the two sampling cylinders engage to form a whole, the corresponding partitions are also spliced together, so as to be able to layer the frozen soil sampled, which is convenient for the staff to analyze the frozen soil at different heights after sampling.

[0018] The following further describes the utility model with reference to the drawings.

[0019] According to Figures 1-5As shown in the figure: The utility model provides a time-saving and labor-saving frozen soil sampling mechanism, which comprises a support frame 1, on which a hydraulic cylinder 2 is arranged; the working end of the hydraulic cylinder 2 is fixedly connected with a support plate 3 located inside the support frame 1, and two sampling cylinders 4 are slidably arranged below the support plate 3; a chute is formed inside the support plate 3, and a sliding structure fixedly connected with the sampling cylinder 4 is slidably arranged in the chute; a sampling tip 5 is fixedly connected to the bottom of the sampling cylinder 4; an installation groove 10 is formed in the inner wall of the sampling cylinder 4, a partition plate 11 is arranged in the installation groove 10, and the partition plate 11 is fixedly connected with the sampling cylinder 4 by screws 13; the two sampling cylinders 4 are corresponding semi-cylindrical shapes, and the partition plate 11 is a semi-cylindrical shape corresponding to the sampling cylinder 4.

[0020] This application uses the hydraulic cylinder 2 to drive the sampling cylinder 4 to move downward. At the same time, with the cooperation of the sampling tip 5, the insertion of the sampling cylinder 4 can be made more time-saving and labor-saving. At the same time, the partition plate 11 is provided. When the two sampling cylinders 4 are engaged to form a whole, the corresponding partition plates 11 are also spliced together, so that the frozen soil sampled can be stratified, which is convenient for the staff to analyze the frozen soil at different heights after sampling.

[0021] As Figure 3 shown, the sliding structure includes sliders 6. There are two sliders 6, and the sliders 6 are slidably arranged in the chute; a guiding groove 7 is formed at the bottom of the support plate 3, and the sliders 6 pass through the guiding groove 7 and are fixedly connected with the sampling cylinder 4. A motor 9 is arranged on one side of the support plate 3, and a bidirectional lead screw 8 rotatably arranged in the chute is fixedly connected to the output shaft of the motor 9; the two sliders 6 are threadedly connected to the corresponding positions on the bidirectional lead screw 8; the chute and the sliders 6 are corresponding cuboid structures, and the sliders 6 are in mutual fit with the inner wall of the chute, which can limit the rotation of the sliders 6, thereby converting the rotation of the bidirectional lead screw 8 into the movement of the sliders 6, and then driving the sampling cylinder 4 to move.

[0022] As Figure 4 、 5 shown, the installation grooves 10 are evenly distributed up and down in the sampling cylinder 4, and counterbore holes 12 are formed in the outer wall of the sampling cylinder 4; the screws 13 are located in the counterbore holes 12; the arrangement of the screws 13 can facilitate the disassembly and installation of the partition plate 11, and the number of separated spaces can be conveniently adjusted by changing the number and position of the partition plate 11. At the same time, the arrangement of the counterbore holes 12 can reduce the resistance generated by the screws 13 when the sampling cylinder 4 is inserted into the frozen soil.

[0023] The sampling tip 5 is semi-conical, and the bottom diameter of the sampling tip 5 corresponds to the diameter of the sampling cylinder 4. When the two sampling cylinders 4 are joined together, the two semi-conical sampling tips 5 can also be joined together to seal the bottom of the sampling cylinder 4 and prevent the frozen soil from falling.

[0024] The principle of the utility model

[0025] As Figures 1-2 shown, when sampling frozen soil, there is a gap between two sampling cylinders 4. Start the hydraulic cylinder 2, and the hydraulic cylinder 2 drives the support plate 3 and the sampling cylinder 4 to move downward. Under the action of the sampling tip 5, the sampling cylinder 4 can quickly insert into the ground. When the sampling cylinder 4 is at a certain depth, as Figure 3 shown, start the motor 9. Driven by the slider 6, the two sampling cylinders 4 move towards each other until the two sampling cylinders 4 are joined together. The frozen soil is located inside the sampling cylinder 4. At this time, the two conical sampling tips 5 are also joined together and can seal the bottom of the sampling cylinder 4 to prevent the frozen soil from falling when the sampling cylinder 4 rises. As Figure 4 、 5 shown, when the two sampling cylinders 4 are joined together, the partitions 11 inside the sampling cylinder 4 are also joined together, thereby stratifying the frozen soil inside the sampling cylinder 4; use the hydraulic cylinder 2 to pull the sampling cylinder 4 upward to complete the sampling, and reverse the motor 9 to separate the two sampling cylinders 4 again, so as to take out the stratified frozen soil samples in turn, which is convenient for the staff to study the frozen soil at different heights.

[0026] Since the partition 11 is fixedly connected to the sampling cylinder 4 by screws 13, the present application can also adjust the height space and quantity of the stratified layers by changing the quantity and position of the partition 11, which is very convenient.

[0027] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, they design similar structural manners and embodiments to this technical solution without creative efforts, all of which should fall within the protection scope of the present utility model.
