Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil sample transfer device. Background Art

[0002] In order to understand the soil resources, in addition to observing the soil profile morphology on site, it is also necessary to collect and analyze samples in order to determine various physical and chemical properties. Soil bulk density sample collection is one of the test items. It is a process of collecting soil samples and measuring their volume and weight to calculate the soil bulk density. The specific collection method is as follows: select a representative location, place the sampling steel cylinder vertically on the ground, hit the steel cylinder with a rubber hammer and insert the steel cylinder into the soil; take out the sampling steel cylinder, turn the sampling steel cylinder upside down, and then use a cutter to cut off the soil column that is higher than the steel cylinder; then carefully transfer the soil column to the fixed volume steel cylinder. The inner diameter of the fixed volume steel cylinder is the same as that of the sampling steel cylinder, but the height of the fixed volume steel cylinder is less than the height of the sampling steel cylinder. Therefore, after the soil column is transferred to the fixed volume steel cylinder, it is necessary to use a cutter to trim the soil column again. After obtaining the volume and weight of the soil column, the soil bulk density can be calculated. The above process has the following problems: the redundant soil columns need to be cut off manually twice; when transferring the soil columns from the sampling steel cylinder to the constant volume steel cylinder, the staff needs to stay focused and be careful. Once the two steel cylinders are not aligned, the soil columns may become loose, affecting the measurement results. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a soil sample transfer device, which automatically transfers the soil column in the sampling steel cylinder to the fixed volume steel cylinder and automatically completes the cutting of the soil column.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

The sampling steel cylinder and the constant volume steel cylinder have the same inner diameter, the former is higher than the latter, and also comprises a turning mechanism, two lifting mechanisms, a positioning mechanism and a limiting mechanism.

[0006] The two lifting mechanisms and the limiting mechanism are both arranged on the bottom plate. When the constant volume steel cylinder is placed on the bottom plate, the limiting mechanism is used to limit the constant volume steel cylinder;

[0007] The flipping mechanism includes a first motor, a second motor, a U-shaped plate, and a turntable. The first motor is arranged on the top of a lifting mechanism, and its output shaft is connected to one side wall of the U-shaped plate.

The top of the second motor is connected to the turntable, and the outer side of the turntable is horizontally connected to the cutter. When the sampling steel cylinder is placed in the U-shaped plate, the positioning mechanism is used to fix the sampling steel cylinder. At this time, the sampling steel cylinder and the fixed volume steel cylinder are located on the same vertical line, the bottom surface of the cutter is flush with the top surface of the sampling steel cylinder, and the width of the cutter is greater than the outer diameter of the sampling steel cylinder.

[0008] Furthermore, the sampling steel cylinder includes a steel plate, a steel column, and a sampling cylinder connected in sequence. Among the three, the outer diameter of the steel column is the smallest. The positioning mechanism includes an inverted L-shaped base and a semicircular clamping ring. A semicircular groove is provided at the end of the transverse section of the inverted L-shaped base. The semicircular clamping ring is aligned with the transverse section of the inverted L-shaped base. One end of the semicircular clamping ring is hinged to the inverted L-shaped base, and the other end is connected to the inverted L-shaped base through a buckle. The area enclosed by the semicircular clamping ring and the semicircular groove matches the outer diameter of the steel column, and the height of the bottom surface of the semicircular clamping ring from the U-shaped plate is consistent with the thickness of the steel plate.

[0009] Furthermore, the limiting mechanism includes a circular ring and two brackets. The circular ring is connected to the bottom plate through the two brackets, and the inner diameter of the circular ring matches the outer diameter of the constant volume steel cylinder.

[0012] Furthermore, a convex plate is provided inwardly on one side wall of the U-shaped plate, and the top of the turntable is closely attached to the convex plate.

The utility model can automatically transfer the soil column in the sampling steel cylinder to the fixed volume steel cylinder, and automatically complete the cutting of the soil columns in the two steel cylinders.

[0018] like Figure 4 As shown, this embodiment provides a soil sample transfer device, including a sampling steel cylinder 11, a constant volume steel cylinder 12, a cutter 13, a turning mechanism 2, two lifting mechanisms 3, a positioning mechanism 4, and a limiting mechanism 5.

[0019] Specifically, the inner diameters of the sampling steel cylinder 11 and the constant volume steel cylinder 12 are the same, and the former is greater than the latter. Figure 3 As shown, the sampling steel cylinder 11 of this embodiment includes a steel plate 111, a steel column 112, and a sampling cylinder 113 connected in sequence, and the outer diameter of the steel column 112 is the smallest among the three.

[0020] Specifically, the two lifting mechanisms 3 and the limiting mechanism 5 are both arranged on the bottom plate 31, and the limiting mechanism 5 is located between the two lifting mechanisms 3. When the constant volume steel cylinder 12 is placed on the bottom plate 31, the limiting mechanism 5 is used to limit the constant volume steel cylinder 12. The specific implementation method of the limiting mechanism 5 is as follows: Figure 1 As shown, it includes a ring 51 and two brackets 52 . The ring 51 is connected to the bottom plate 31 through the two brackets 52 . The inner diameter of the ring 51 matches the outer diameter of the constant volume steel cylinder 12 .

[0021] When in use, the constant volume steel cylinder 12 is placed in the ring 51. In order to facilitate the placement or removal of the constant volume steel cylinder 12, a handle 121 is provided on the side wall of the constant volume steel cylinder 12, and a notch 511 is provided on the ring 51.

[0022] Specifically, the flip mechanism 2 includes a first motor 21, a second motor 22, a U-shaped plate 23, and a turntable 24. The first motor 21 is arranged at the top of a lifting mechanism 3. The output shaft of the first motor 21 is connected to one side wall of the U-shaped plate 23. The other side wall of the U-shaped plate 23 is rotatably connected to the top of another lifting mechanism 3. The lifting mechanism 3 can be a lifting rod driven by a cylinder, an oil cylinder or a hydraulic pressure. The second motor 22 and the positioning mechanism 4 are both arranged in the U-shaped plate 23. The top of the second motor 22 is connected to the turntable 24. The outer side of the turntable 24 is horizontally connected to the cutter 13. In order to increase stability, a convex plate 231 is provided inwardly on one side wall of the U-shaped plate 23, and the top of the turntable 24 is close to the convex plate 231.

[0023] When the sampling steel cylinder 11 is placed in the U-shaped plate 23, the sampling steel cylinder 11 and the constant volume steel cylinder 12 are located on the same vertical line, the bottom surface of the cutter 13 is flush with the top surface of the sampling steel cylinder 11, and the width of the cutter 13 is greater than the outer diameter of the sampling steel cylinder 11. The cutter 13 serves to cut off excess soil columns of the sampling steel cylinder 11 and is also used to seal the sampling steel cylinder 11 after cutting off the soil columns.

[0024] The positioning mechanism 4 is used to fix the sampling steel cylinder 11, and the specific implementation method is as follows: Figure 1 , Figure 2As shown, the positioning mechanism 4 includes an inverted L-shaped base 41 and a semicircular snap ring 42. A semicircular groove 411 is provided at the end of the transverse section of the inverted L-shaped base 41. The semicircular snap ring 42 is aligned with the transverse section of the inverted L-shaped base 41. One end of the semicircular snap ring 42 is hinged to the inverted L-shaped base 41, and the other end is connected to the inverted L-shaped base 41 through a buckle. The buckle is a conventional component and its structure is no longer specifically shown. The area enclosed by the semicircular snap ring 42 and the semicircular groove 411 matches the outer diameter of the steel column 112, and the height of the bottom surface of the semicircular snap ring 42 from the U-shaped plate 23 is consistent with the thickness of the steel plate 111.

[0025] When in use, open the buckle of the semicircular clamping ring 42, place the sampling steel cylinder 11 with the collected soil sample in the semicircular groove 411, and close the semicircular clamping ring 42; the second motor 22 drives the turntable 24 to make the cutter 13 cut the soil column of the sampling steel cylinder 11, and the cutter 13 covers the top of the sampling steel cylinder 11 after cutting; place the fixed volume steel cylinder 12 in the ring 51, and pay attention to placing the fixed volume steel cylinder 12 after the soil column of the sampling steel cylinder 11 is cut to prevent soil from falling into the fixed volume steel cylinder 12; the first motor 21 drives the U-shaped plate 23 to flip 180°, and uses the lifting mechanism 3 to move the U-shaped plate 23 downward until the cutter 13 contacts the fixed volume steel cylinder 12; the second motor 22 drives the turntable 24 to keep the cutter 13 away from the sampling steel cylinder 1 1, the soil column in the sampling steel cylinder 11 falls into the constant volume steel cylinder 12; then the second motor 22 reversely drives the turntable 24 to move the cutter 13 between the sampling steel cylinder 11 and the constant volume steel cylinder 12 again. At this time, the cutter completes the removal of the excess soil column of the constant volume steel cylinder 12 and closes the sampling steel cylinder 11 again. In order to prevent the accumulation of soil on the top surface of the ring 51 when cutting the excess soil column in the constant volume steel cylinder 12, the top surface of the constant volume steel cylinder 12 in this embodiment is flush with the top surface of the ring 51; then the lifting mechanism 3 rises and resets, and the flipping mechanism 2 flips 180° and resets; the constant volume steel cylinder 12 is taken out, and the volume and weight of the soil column in the constant volume steel cylinder 12 are calculated, and then the soil bulk density is obtained; the sampling steel cylinder 11 is taken out, and the soil inside is poured out for next use.

[0026] In summary, the present embodiment is easy to use, and can automatically transfer the soil column in the sampling steel cylinder 11 to the constant volume steel cylinder 12, and automatically complete the cutting of the soil columns in the two steel cylinders.
