Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil analysis technology, specifically to a soil analyzer. Background Technology
[0002] When analyzing the pH of solid soil, it is impossible to accurately detect the pH value directly using a probe. Soil samples need to be excavated or drilled to prepare a soil suspension with a soil-to-water ratio of 1:2.5 or 1:5. In existing technologies, soil suspensions generally require manual mixing of soil and water, which is cumbersome and prone to introducing impurities, leading to inaccurate test results. Therefore, a soil analyzer is designed. Utility Model Content
[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a soil analyzer that can mix soil suspensions in a specific ratio, avoiding the introduction of other impurities during the preparation of soil suspensions, and thus providing more accurate test results.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A soil analyzer includes a base shell, a controller and a display screen embedded in the front of the base shell, a mixing tank mounted on the base shell, a lifting assembly for lifting the mixing tank, and a weighing assembly disposed between the mixing tank and the base shell. The top of the mixing tank is provided with a feed inlet and a liquid inlet pipe, and a water inlet pipe with one end extending into the liquid inlet pipe. The mixing tank is provided with a detection assembly and a stirring assembly, and a connecting frame for fixing the water inlet pipe to the base shell. A piston-type solenoid valve is provided on the water inlet pipe. The lifting assembly, weighing assembly, detection assembly, stirring assembly, display screen, and piston-type solenoid valve are all electrically connected to the controller.
[0006] Furthermore, the lifting assembly includes a lifting electric cylinder installed inside the bottom shell, a lifting seat slidably connected to the bottom shell, and a lifting frame with its bottom end fixed on the lifting seat.
[0007] Furthermore, the lifting frame includes multiple L-shaped brackets disposed above the bottom shell, with a connecting rod whose top end is fixed to the vertical part of the L-shaped bracket and whose bottom end passes through the bottom shell and is fixedly connected to the lifting seat, for connecting the positioning rings of the vertical parts of the multiple L-shaped brackets. The multiple L-shaped brackets are arranged at equal angles with the axis of the positioning ring as the center, and anti-slip and shock-absorbing pads are provided on both the horizontal and vertical parts of the L-shaped brackets.
[0008] Furthermore, the weighing assembly includes four weighing sensors, which are fixed on the bottom shell. The detection end of each weighing sensor is connected to a weighing plate facing upwards. When the lifting frame is in the lowering state, the bottom of the mixing tank abuts against the weighing plate.
[0009] Furthermore, the stirring assembly includes a mixing shaft rotatably connected inside the mixing tank, multiple mixing blades disposed on the mixing shaft, a mixing motor fixed to the top of the mixing tank, and the top end of the mixing shaft extending out of the mixing tank and connected to the output shaft of the mixing motor.
[0010] Furthermore, the detection assembly includes an electrically operated telescopic rod detachably connected to the top wall of the mixing tank. The piston rod of the electrically operated telescopic rod extends vertically downward and is driven to connect to a detection seat. A detection probe extends from the bottom end of the detection seat.
[0011] Furthermore, a drain pipe is provided on the rear side of the mixing tank, which connects to the interior of the mixing tank, and a manual valve is provided on the drain pipe.
[0012] Furthermore, the controller includes a storage module, a calculation module, and a control module. The storage module and the calculation module are both electrically connected to the control module. The storage module is used to store the soil weight, the calculation module is used to calculate the water volume based on the soil weight, and the control module controls the lifting assembly, the detection assembly, the stirring assembly, the display screen, and the piston-type solenoid valve based on the calculation results of the calculation module.
[0013] The beneficial effects of this utility model are:
[0014] In practical applications, during use, the lifting assembly drives the support frame to descend, connecting the weighing assembly to the mixing tank. Soil samples are then fed into the mixing tank through the inlet. The weighing assembly weighs the soil sample and sends the result to the controller. The controller controls the piston-type solenoid valve based on the soil weight, which in turn controls the amount of water injected into the mixing tank through the water inlet pipe. After water injection is complete, the piston-type solenoid valve closes the water inlet pipe, and the lifting assembly drives the support frame to rise, separating the weighing assembly from the mixing tank. The stirring assembly then mixes the soil sample and water to form a soil suspension. The detection assembly measures the pH of the soil suspension. This invention allows for precise mixing of the soil suspension, preventing the introduction of other impurities during preparation and resulting in more accurate test results.

[0019] In use, the lifting assembly drives the support frame to descend, connecting the weighing assembly 5 to the mixing tank 4. Soil samples are fed into the mixing tank 4 through the inlet 41. The weighing assembly 5 weighs the soil sample and sends the result to the controller 2. The controller 2 controls the piston-type solenoid valve 61 based on the soil weight, controlling the amount of water injected into the mixing tank 4 through the water inlet pipe 6. After water injection, the piston-type solenoid valve 61 closes the water inlet pipe 6, and the lifting assembly drives the support frame to rise, separating the weighing assembly 5 from the mixing tank 4. The stirring assembly mixes the soil sample and water to form a soil suspension. The detection assembly measures the pH of the soil suspension.
