Description

Technical Field

[0001] This utility model relates to the field of soil sample testing technology, and more specifically, to a soil-water mixing and homogenization device. Background Technology

[0002] Currently, the main method for homogenizing soil samples before liquid limit and plastic limit testing is manual kneading. This involves repeatedly kneading the soil with both hands and relying on experience to judge whether the mixture is homogeneous. This manual kneading process is cumbersome, and it's difficult to maintain consistent kneading force, time, and homogenization levels. Furthermore, the soil sample is exposed to an open environment for an extended period, which may cause fluctuations in moisture content and affect the consistency of soil sample preparation. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water and soil mixing and homogenization device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-4As shown, a water and soil mixing and homogenization device includes a rectangular frame 1, an outer shell 2 covering the outside of the frame 1, a lifting mechanism 3 on the frame 1, and an upper kneading plate 4 driven by the lifting mechanism 3.

[0021] The lifting mechanism 3 includes a lifting frame 7 mounted on the frame 1, with a portion of the lifting frame 7 extending through the upper end face of the outer casing 2. A lead screw motor 8 is mounted at the lower part of the lifting frame 7, and a lead screw 9 is rotatably mounted on the lifting frame 7. The lead screw motor 8 drives and connects to the lead screw 9. A lead screw slider 10 is mounted on the lead screw 9, and a crossbeam 11 is connected to the lead screw slider 10. An upper kneading plate 4 is mounted at the lower part of the crossbeam 11.

[0022] The lifting mechanism 3 can control the distance between the upper kneading plate 4 and the lower kneading plate 5, which can meet the needs of airbags of different sizes.

[0023] Below the upper kneading plate 4, a lower kneading plate 5 is provided. The lower kneading plate 5 is located on the upper surface of the outer shell 2. The lower part of the lower kneading plate 5 is connected to a support base 21. The lower end of the support base 21 is connected to a drive rod 22. The upper part of the frame 1 is provided with a mounting plate 18. The lower part of the mounting plate 18 is equipped with a drive motor 19. The drive motor 19 drives and connects to a crank 20. A slot 25 is provided on the crank 20. The lower end of the drive rod 22 is located in the slot 25.

[0024] A sealed airbag containing a mud-water mixture sample is placed on the lower kneading plate 5. A lead screw motor 8 drives a lead screw 9 to rotate, which in turn moves a crossbeam 11 downwards via a lead screw slider 10, causing the upper kneading plate 4 to press against the airbag. The upper and lower kneading plates 4 and 5 are tightly fitted against the airbag. The drive motor 19 is activated, driving a crank 20 to rotate. The crank 20, through a latch 25, drives a drive rod 22, which in turn, through a support 21, causes the lower kneading plate 5 to rotate. This back-and-forth kneading action of the upper and lower kneading plates 4 and 5 simulates the kneading motion between human hands. This kneading action ensures the mud-water mixture inside the airbag is fully integrated, resulting in a homogeneous mud-water mixture with constant moisture content.

[0025] The process of homogenizing the mud sample with water and soil takes place in a closed air chamber. During the kneading process, no water evaporation occurs, ensuring that the moisture content of the mud sample remains unchanged.

[0026] like Figure 2 As shown, a protective cover 12 is provided on the outside of the crossbeam 11 to protect the crossbeam 11.

[0027] like Figure 2As shown, a connecting block 13 is connected to the end of the crossbeam 11 away from the lead screw slider 10. A lifting rod 14 is connected to the connecting block 13. A guide seat 15 is provided on the frame 1, and the lifting rod 14 passes through the guide seat 15. The lifting rod 14 is guided to rise and fall by the guide seat 15, so that the crossbeam 11 rises and falls smoothly, and the upper kneading plate 4 remains horizontal.

[0028] like Figure 3 As shown, the lower end of the lifting rod 14 is connected to the detection plate 16. A limit switch 17 is set at the position above and below the detection plate 16 in the frame 1. The two limit switches 17 are used as the upper and lower limits of the detection plate 16, respectively, to control the lifting height of the upper kneading plate 4.

[0029] like Figure 4 As shown, a linear bearing slider 23 is installed on the lower part of the lower kneading plate 5. A limiting block 26 is located on the frame 1 at the front and rear sides of the linear bearing slider 23. An mounting block 27 is installed inside the limiting block 26, and the outer side of the mounting block 27 abuts against the limiting block 26. A guide rod 24 connects the two mounting blocks 27, and the linear bearing slider 23 is slidably mounted on the guide rod 24. The cooperation between the linear bearing slider 23 and the guide rod 24 guides the movement of the lower kneading plate 5 in the front-back direction, and the cooperation between the limiting block 26 and the mounting block 27 guides the movement of the lower kneading plate 5 in the left-right direction.

[0030] An opening 28 is provided on the upper surface of the outer casing 2. The linear bearing slider 23 and the support base 21 are disposed through the opening 28. The size of the opening 28 is sufficient to accommodate the movement range of the linear bearing slider 23 and the support base 21 when the lower kneading plate 5 rotates. A dustproof plate 6 is provided at the lower part of the lower kneading plate 5. The dustproof plate 6 moves with the lower kneading plate 5 and keeps covering the opening 28 during the movement, thereby preventing external impurities from entering through the opening 28 and avoiding external impurities from affecting the operation of the device.

[0031] Furthermore, several support feet 29 are installed at the bottom of the frame 1 to support the entire device and ensure stable operation.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
