Description

Technical Field

[0001] The utility model relates to the technical field of soil particle specific gravity testing, in particular to a soil particle specific gravity detection device. Background Art

[0002] The specific gravity of soil particles is one of the basic physical properties of soil and a key indicator for calculating porosity and evaluating soil types. Common methods for measuring the specific gravity of soil particles in geotechnical testing regulations include the float weighing method, the buoyancy method, and the pycnometer method. The float weighing method requires suspending the sample in water and measuring its weight in water. The "Highway Geotechnical Testing Regulations" disclose the use of a float weighing balance for testing the weight of soil particle samples in water. The method for measuring specific gravity using a float weighing balance involves first rinsing the soil particle sample, then soaking it in water for a day and a night. Immediately after soaking, the sample is placed in a metal basket and suspended in water, connected to the basket, for weight measurement. The measured weight is then used to calculate the specific gravity. This existing method requires rinsing, then soaking, and finally transferring the sample to the metal basket for weighing. This method involves multiple steps, a cumbersome process, and a long soaking time, resulting in a long testing cycle and low efficiency. This method is not suitable for simultaneous specific gravity testing of multiple batches of samples. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a soil particle specific gravity detection device for detecting the specific gravity of soil particles, so as to solve the problems of cumbersome operation and low detection efficiency in the prior art when detecting the specific gravity of soil particles.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] In this solution, when conducting a specific gravity test on a soil particle sample, a sample basket containing the soil particle sample is placed on a flushing mechanism, and the control system controls the flushing mechanism to automatically flush the soil particle sample inside the sample basket, and the sample continues to be immersed in the container after flushing; when the immersion time is up, the control system controls the weighing mechanism to weigh the sample basket and its particles, and after weighing, the specific gravity can be calculated based on the weight of the sample in water; when using the device to measure the weight of the sample in water, it is only necessary to place the sample into the sample basket, and no other operation is required, and the measurement process is simple; and when the sample immersion time is reached, the control system controls the weighing mechanism to automatically measure the weight, and there is no need to manually wait for the immersion time to end, saving time.

[0007] Furthermore, the weighing mechanism includes a lifting motor, which is arranged at the top of the support frame; a pulley is connected to the output shaft of the lifting motor; one end of the connecting rope is wrapped around the pulley, and the other end of the rope passes through the pulley group and is connected to the bottom of the electronic crane scale, and the electronic crane scale is suspended on the support frame; the sample basket is movably connected to the pulley group through a connecting rod.

[0008] In this solution, a rope is connected to the sample basket through a pulley set.

Even if a small-range electronic crane scale is used, the measurement can be achieved.

[0011] Furthermore, an electromagnetic chuck is provided at one end of the connecting rod connected to the sample basket, and the electromagnetic chuck is connected to the permanent magnet on the top of the sample basket through magnetic attraction.

[0015] Furthermore, the driving assembly includes a pulley connected to the bottom of the connecting shaft; the pulley is connected to a driving motor through a belt transmission; the driving motor drives the rotating disk to rotate through the belt transmission, and the rotating disk drives the sample basket to rotate.

[0016] In this solution, the driving motor is connected to the pulley via a belt, thereby driving the rotating disk to rotate. The structure is simple and easy to implement.

[0017] Furthermore, the control system includes: a controller, a water level sensor, a water temperature sensor and a touch screen; the water level sensor, the water temperature sensor and the touch screen are all connected to the controller; the water level sensor and the water temperature sensor are both arranged at the bottom of the container, and the touch screen is arranged on the support frame;

[0018] The controller is electrically connected to the lifting motor and the driving motor; the controller is electrically connected to the electromagnetic suction cup.

[0019] In this solution, the water level sensor can collect the water level in the container to prevent the water level inside the container from being too low to completely immerse the sample, resulting in inaccurate measurement results; the temperature sensor can collect the water level and send it to the controller; the flushing time and soaking time of the flushing mechanism can be set through the touch screen, as well as the height to which the weighing device lifts the sample basket and sends them to the controller.
