Description

Technical Field

[0001] The utility model belongs to the technical field of soil particle analysis equipment, in particular to a test tube mounting bracket for soil particle analysis. Background Art

[0002] Soil particle analysis refers to the analysis and study of the components of different particle sizes in the soil, which is of great significance for understanding the physical properties, moisture characteristics, fertility, etc. of the soil;

[0003] Through detailed analysis of soil particles, we can better understand the physical properties (such as permeability and water retention), chemical properties (such as ion exchange capacity) and biological properties (such as microbial growth environment) of the soil, providing a scientific basis for soil improvement and agricultural production;

[0004] In the soil analysis experiment, the test soil is first placed in the test solution and stirred evenly with a stirring rod to allow the solution and soil to fully blend. After fusion, according to the manual standards, the soil solution is allowed to stand for a period of time, then placed on a sampling rack and the liquid is sampled using an instrument.

[0005] Due to the different diameters of soil particles, the stirring time, the depth of the sampler inserted into the test tube and the sampling volume are all different during the sampling process. At present, the test tube butterfly clamp is used manually to continuously replace the instrument to meet the sampling of soil particles of different diameters. This method leads to cumbersome operation steps and reduces the technical problem of sampling efficiency.

[0006] Therefore, the utility model designs a test tube mounting bracket for soil particle analysis to solve the technical problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0025] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-4 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0026] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0027] Embodiment 1, a test tube mounting bracket for soil particle analysis, comprising a bottom plate 1 and a top plate 2, characterized in that:

[0028] The bottom plate 1 and the top plate 2 are connected with a retractable plate 3, and the top plate 2 is rotatably connected with a rotating plate 4, and the rotating plate 4 is driven by a power device;

[0029] The rotating plate 4 is provided with two groups of placement holes 5, and two or more groups of auxiliary clamping plates 6 are arranged in the two groups of placement holes 5 along the circumferential direction, and a clamping spring 7 is arranged between the auxiliary clamping plates 6 and the placement holes 5;

[0030] The bottom of the rotating plate 4 is slidably connected with two sets of main plates 8 corresponding to the placement holes 5, and the rotating plate 4 is rotatably connected with an adjusting screw 9 threadedly connected with the main plates 8, and one end of the adjusting screw 9 is provided with an adjusting handle 10;

[0031] A telescopic rod 11 is disposed in one group of the placement holes 5, and a stirring rod 12 is disposed at the output end of the telescopic rod 11, and a pipette 13 is disposed in another group of the placement holes 5;

[0032] The bottom plate 1 is provided with a soil sample container 14 and a soil sampling container 15 .

[0033] Furthermore, the power device includes a motor 16 disposed on the top plate 2, the rotating plate 4 is driven by the motor 16, and the motor 16 is electrically connected to the controller.

[0034] Furthermore, the retractable plate 3 is an electric retractable plate, and the electric retractable plate is electrically connected to the controller.

[0035] Furthermore, the telescopic rod 11 is an electric telescopic rod, and the electric telescopic rod is electrically connected to the controller.

[0036] Furthermore, both the auxiliary splint 6 and the main splint 8 are provided with anti-slip pads.

[0037] Furthermore, the bottom plate 1 is provided with a shock-absorbing pad.

[0038] When in use, the telescopic rod 11 and the pipette are placed in the placement hole 5. Under the action of the clamping spring 7, the auxiliary splint 6 contacts the pipette 13 and the telescopic rod 11, and the pipette 13 and the telescopic rod 11 can be initially fixed, so as to facilitate the adjustment of the position of the pipette 13 and the telescopic rod 11 in the placement hole 5. After the adjustment is completed, the adjustment handle 10 is rotated to drive the adjustment screw 9 to rotate, so that the main splint 8 moves in the direction of the adjustment pipette 13 and the telescopic rod 11 until the adjustment pipette 13 and the telescopic rod 11 are clamped. Anti-slip pads are provided on the auxiliary splint 6 and the main splint 8 to further clamp the pipette 13 and the telescopic rod 11.

[0039] After installation, the test soil and liquid are placed in the soil sample container 14, and the stirring time and the depth of the pipette 13 inserted into the soil sample container 14 are controlled according to the diameter of the test soil;

[0040] First, the motor 16 is controlled to drive the rotating plate 4 to move so that the stirring rod 12 corresponds to the soil sample container 14, and the height of the telescopic rod 11 is adjusted according to the height of the soil sample container 14;

[0041] During stirring, the retractable plate 3 is controlled to move so that the stirring rod 12 can move back and forth vertically along the soil sample container 14. Since the stirring rod 12 is provided with a disc having an array of holes, the stirring rod 12 is located at the bottom of the soil sample container 14 and then rises under the action of the retractable plate 3. When the disc of the stirring rod 12 rises, it should not leave the liquid surface.

[0042] After stirring for a specified time, let it stand for the first 15 seconds of the specified time, drive the motor 16 to make the pipette 13 correspond to the soil sample container 14, and adjust the vertical position of the pipette 13 through the retractable plate 3 to meet the specified depth of the sampling liquid surface. Press the switch of the pipette 13 to achieve the purpose of automatic quantitative sampling. After the sampling is completed, drive the motor 16 to make the rotating plate 4 move, so that the pipette 13 corresponds to the soil sampling container 15, and put its sampling liquid into the soil sampling container 15 to complete the sampling work;

[0043] This method avoids manual stirring, simplifies the sampling operation steps, effectively improves the sampling efficiency, and at the same time improves the sampling accuracy.

[0044] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
