[0016] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-2 As shown, the multifunctional soil dilution device for soil detection comprises a dilution box 1 and a dilution cup 2, wherein the dilution box 1 has a placement cavity 11 for placing the dilution cup 2, a weighing device 12 is provided at the bottom of the placement cavity 11, a heating seat 13 is provided on the top of the weighing device 12, and a control screen 14 is provided on one side of the dilution box 1. By heating the dilution cup 2, the moisture in the detected soil in the dilution cup 2 evaporates, and the moisture content of the soil is detected;

[0018] The port of the dilution cup 2 is threadedly connected with a closing cover 3, and a rotating motor 31 is arranged inside the closing cover 3. The power output shaft 32 of the motor 31 extends to the bottom of the dilution cup 2, and a stirring screw 33 is arranged on the power output shaft 32. Mechanical energy is used for sealed stirring during soil dilution to improve dilution efficiency;

[0019] The multifunctional soil dilution device for soil detection further comprises a processor 4 connected to a weighing device 12, a heating seat 13 and a control screen 14 respectively, so as to simplify operation and facilitate reading.

[0020] During implementation, the dilution cup 2 is weighed by the weighing device 12, and the measured data is fed back to the processor 4. The soil sample to be tested is added to the dilution cup 2, and the dilution cup 2 is weighed again, and the data is fed back to the processor 4. The obtained data is processed by the processor 4 to calculate the mass of the soil sample. Then, the heating seat 13 is turned on by the control screen 14 to dry the soil sample in the dilution cup 2, and the dilution cup 2 is weighed again. The water content of the soil sample and the mass of the soil sample after drying are calculated by the processor 4 and displayed on the control screen 14. The user calculates the required mass of the diluent according to the required soil dilution degree and with reference to the mass of the dried soil sample. Then, the required mass of the dilution is added to the dilution cup 2, and the addition port of the dilution cup 2 is closed by the closing cover 3. At the same time, the stirring motor 31 is powered on. When the stirring motor 31 rotates, it drives the stirring screw 33 to rotate, thereby causing the soil sample and the diluent to melt.

[0021] As a preferred solution of the above embodiment, the dilution cup 2 is made of metal material.

[0022] As a preferred solution of the above embodiment, in order to reduce the influence of the heat energy generated during the operation of the heating seat 13 on the controller 4 and the weighing device 12 inside the dilution box 1, a gap is provided between the dilution cup 2 and the placement cavity 11, the cavity wall of the placement cavity 11 is made of a heat-insulating material, and the cavity wall is provided with a heat dissipation hole 15, and the heat dissipation hole 15 extends to the outside of the dilution box 1 through a pipeline.

[0023] As a preferred solution of the above embodiment, during stirring, the position of the dilution cup 2 is fixed by limiting the position of the closing cover 3 to avoid the centripetal force generated by the liquid in the dilution cup 2 during rotation, so that the dilution cup 2 and the cavity wall of the placement cavity 11 collide with each other. A limiting ring 16 for limiting the position of the closing cover 3 is provided on the top of the dilution box 1.

[0024] The above-described embodiments only express specific implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
