Technical Field

[0001] The utility model relates to the technical field of soil test equipment, in particular to a liquid-plastic limit soil adjusting container device that can save time and effort. Background Technique

[0002] Usually when we do geotechnical test data, one of the indicators is to determine the liquid limit and plastic limit of the soil sample. The most commonly used instrument now is the liquid-plastic limit combined determination instrument. The operation steps are to select a soil sample that meets the regulations, fully adjust the soil sample, and evenly stir and layer the prepared soil sample into the soil cup. Place the test cup filled with the soil sample on the instrument and measure the corresponding data. In actual operation, in order to test 3 qualified points, a lot of time and physical strength will be spent. Especially in the process of adjusting the soil sample, the current traditional method is to place the soil sample on the board and constantly stir it with a soil adjusting knife, or use a hammer to pound it, a water absorber to dilute it, a hair dryer to dry it, etc. Repeat these operations over and over again. A lot of experience needs to be accumulated in this process. If it is a novice, it takes at least about 1 hour to measure the liquid-plastic limit of a soil sample. At this work efficiency, it is best to measure 8 soil samples a day, which greatly reduces the work efficiency of the test personnel. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-8, the present utility model provides a technical solution: a liquid-plastic limit adjusting soil container device that can save time and effort, including a mixing barrel 1, a barrel cover 2 is arranged at the upper end of the mixing barrel 1, a motor 3 is fixedly installed on the upper side of the barrel cover 2, a rotating shaft 4 is rotatably connected to the center of the inner cavity of the mixing barrel 1, the upper end of the rotating shaft 4 penetrates through the barrel cover 2 and is in transmission connection with the output shaft of the motor 3, a plurality of mixing paddles 5 for mixing the soil in the mixing barrel 1 are arranged on the side wall of the rotating shaft 4, a water injection pipe 6 for adding water into the mixing barrel 1 is arranged on the barrel cover 2, the lower end of the water injection pipe 6 is communicated with the inner cavity of the mixing barrel 1, and a heat injection pipe 7 for injecting hot air required for drying the soil into the mixing barrel 1 is also arranged on the barrel cover 2, the lower end of the heat injection pipe 7 is communicated with the inner cavity of the mixing barrel 1.

[0027] Mixing function: The motor 3 is fixed on the barrel cover 2 and is connected to the rotating shaft 4 at the center of the inner cavity of the mixing barrel 1 through a transmission device. When the motor is started, it drives the rotating shaft 4 to rotate, and then drives a plurality of mixing paddles 5 fixed on the side wall of the rotating shaft to rotate. The rotating action of the mixing paddles 5 can effectively mix the soil in the mixing barrel 1 evenly. Whether adding water or mixing other substances, a good mixing effect can be achieved.

[0028] Water adding function: A water injection pipe 6 is arranged on the barrel cover 2, and its lower end is communicated with the inner cavity of the mixing barrel 1. Through the water injection pipe 6, an appropriate amount of water can be added into the mixing barrel 1 to adjust the water content of the soil, thereby changing the liquid-plastic limit state of the soil. The addition of water is both convenient and precise, which helps to achieve precise adjustment of the liquid-plastic limit of the soil.

[0029] Heating and drying function: In order to cope with the scenario where the soil needs to be dried to adjust its properties, a heat injection pipe 7 is also arranged on the barrel cover 2, and its lower end is also communicated with the inner cavity of the mixing barrel 1. Through the heat injection pipe 7, high-temperature hot air can be injected into the mixing barrel 1 to heat and dry the soil. The excess water in the soil can be removed quickly and evenly, thereby achieving the purpose of adjusting the liquid-plastic limit of the soil.

[0030] As Figure 2 , 5 shown, in order to improve the mixing efficiency of the mixing paddles 5 for the soil in the mixing barrel 1, specifically, a connecting sleeve 8 is fixedly sleeved on the rotating shaft 4, and a plurality of mixing paddles 5 are evenly arranged on the connecting sleeve 8.

[0031] The connecting sleeve 8 serves as a support and connection structure for the mixing paddles 5. It enables the mixing paddles 5 to be stably installed on the rotating shaft and move synchronously with the rotation of the rotating shaft 4. A plurality of mixing paddles 5 are evenly arranged on the connecting sleeve 8, ensuring that the mixing paddles 5 can cover a wider area in the mixing barrel 1, reducing the mixing blind area. At the same time, the evenly distributed mixing paddles 5 can generate a more uniform and strong mixing force, promoting the full mixing of soil particles.

[0032] As Figure 2 、 5 shown, in order to further improve the stirring efficiency of the stirring paddle 5 on the soil in the stirring barrel 1, specifically, each stirring paddle 5 is horizontally arranged, and the paddle surface of each stirring paddle 5 is inclined.

[0033] Each stirring paddle 5 is horizontally arranged, and its paddle surface is inclined. This enables the stirring paddle 5 to generate stronger shear force and stirring force during rotation. The horizontally arranged stirring paddle 5 can more effectively cut soil clumps, while the inclined paddle surface can guide soil particles to circulate in the stirring barrel 1, thereby achieving more thorough mixing.

[0034] As Figures 4-6 and Figure 8 shown, in order to improve the drying efficiency of the soil in the stirring barrel 1, specifically, an air duct 801 is provided inside the connecting sleeve 8, a connecting ring 9 is fixed to the lower end surface of the barrel cover 2, the connecting ring 9 is sleeved on the rotating shaft 4, and the lower end of the heat injection pipe 7 is communicated with the upper end of the air duct 801 by the connecting ring 9. The lower end of the connecting ring 9 is sleeved on the upper end of the connecting sleeve 8, and the lower end of the heat injection pipe 7 is fixed to the connecting sleeve 8, so that the connecting ring 9 communicates the heat injection pipe 7 with the air duct 801, and the hot air injected into the heat injection pipe 7 will flow into the inside of the air duct 801 from the connecting ring 9;

[0035] The inside of the stirring paddle 5 is hollow, inclined air grooves 802 are provided on the side wall of the air duct 801, the hollow inner cavity of the stirring paddle 5 is communicated with the air duct 801 through the air grooves 802, a plurality of partition plates 10 corresponding to the air grooves 802 are arranged inside the air duct 801, the partition plates 10 are horizontally arranged, a part of the air groove 802 is communicated with the air duct 801 above the partition plate 10, and the other part of the air groove 802 is communicated with the air duct 801 below the partition plate 10. A net plate 12 for guiding hot air to the inside of the stirring barrel 1 is provided on the lower side surface of the lowermost stirring paddle 5.

[0036] As Figure 4 、 Figure 8 shown, in order to improve the heating efficiency of the hot air on the stirring paddle 5, specifically, partition strips 11 are fixed on the partition plates 10, and the partition strips 11 extend from the air grooves 802 into the hollow inner cavity of the stirring paddle 5 and divide the hollow inner cavity of the stirring paddle 5 into a "U" - shaped cavity.

[0037] A plurality of stirring paddles 5 are arranged in two rows on the connecting sleeve 8. Two air channels 801 are arranged inside the connecting sleeve 8. Each air channel 801 conveys hot air to the hollow inner cavity of the corresponding row of stirring paddles 5. Through the arrangement of the partition plate 10 and the partition strip 11, the flow path of the hot air is as follows: The hot air enters the air channel 801 from the upper end of the air channel 801. The uppermost partition plate 10 divides the air channel 801. The hot air will enter the hollow inner cavity of the uppermost stirring paddle 5 from a part of the uppermost air groove 802 above the partition plate 10. Due to the arrangement of the partition strip 11, the hot air flows in a U shape inside the uppermost stirring paddle 5. During this process, the hot air heats the stirring paddle 5, making the stirring paddle 5 itself also become a heat source, which helps to improve the drying efficiency. Then, it enters the air channel 801 from a part of the uppermost air groove 802 below the partition plate 10. Then, the hot air flows downward in sequence according to the above flow path. Finally, the hot air flows into the lowermost stirring paddle 5, and the hot air is evenly released into the stirring barrel 1 through the mesh holes of the mesh plate 12 to dry the soil. The hot air entering the stirring barrel 1 flows upward and can then be discharged from the water injection pipe 6, which is beneficial to discharging the soil moisture.

[0038] As Figure 6 shown, in order to be able to seal the connection between the connecting ring 9 and the connecting sleeve 8 and prevent soil from entering the air channel 801. Specifically, the connecting ring 9 and the connecting sleeve 8 are rotatably connected, and a sealing ring 13 is arranged at the connection between the connecting ring 9 and the connecting sleeve 8.

[0039] As Figure 3 、 Figure 5 and Figure 7 shown, in order to be able to improve the crushing efficiency of the soil. Specifically, transverse cutting knives 14 are arranged on the lower sides of a plurality of stirring paddles 5, and a plurality of vertical cutting knives 15 are vertically distributed between a plurality of stirring paddles 5.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
