[0031] In the embodiments of the present application, Figure 2 and Figure 4 As shown, the boosting mechanism includes a driving gear 13 arranged inside the boosting box 3, one side of the driving gear 13 is meshedly connected to a driven gear 14, and the bottom of the driven gear 14 is fixedly connected to the stirring shaft 4.
[0032] By adopting the above technical solution, the device can utilize the boosting mechanism to drive the stirring shaft 4 to rotate, so that the stirring shaft 4 can drive the stirring blades 5 to fully mix the dilution liquid and soil inside the mixing preparation box 1.
[0033] In the embodiments of the present application, Figure 2-3 As shown, the drive mechanism includes a drive disk 10 arranged inside the drive box 6, and a plurality of drive blades 11 are fixedly connected to the outer surface of the drive disk 10. A drive shaft 12 is fixedly connected to the bottom of the drive disk 10, and the bottom of the drive shaft 12 extends to the interior of the boost box 3 and is fixedly connected to the driving gear 13.
[0034] By adopting the above technical solution, the device uses water pressure as the power source for stirring, thereby greatly reducing the loss of electric energy and further greatly improving the energy saving performance of the device.
[0035] In the embodiments of the present application, Figure 4 As shown, the inner diameter of the driving gear 13 is smaller than the inner diameter of the driven gear 14 .
[0036] By adopting the above technical solution, since the small gear drives the large gear to rotate more labor-saving, the device can more easily drive the driven gear 14 to rotate.
[0037] In the embodiments of the present application, Figure 1 As shown, a boost valve 9 is provided on the outer surface of the pipeline connecting the liquid pump 8 and the drive box 6 .
[0038] By adopting the above technical solution, the booster valve 9 can be used to increase the water pressure, thereby achieving a better driving effect.
[0039] In the embodiments of the present application, Figure 2 As shown, a plurality of heating plates 19 are fixedly connected to the bottom of the box cover 2 .

[0045] During use, the operator first puts the soil to be mixed into the mixing preparation box 1 through the feed port 15, and then starts the liquid pump 8 through the controller 18 to input the diluent into the mixing preparation box 1 through the pipeline. When the diluent is input, it will pass through the drive box 6 under the pressure of the booster valve 9, so that the drive blade 11 inside the drive box 6 can rotate under the action of water pressure. When the drive blade 11 rotates, it will drive the drive disk 10 to rotate. When the drive disk 10 rotates, it will drive the drive shaft 12 to rotate. When the drive shaft 12 rotates, it will drive the driving gear 13 to rotate. When the driving gear 13 rotates, it will drive the driving gear 13 to rotate. The driven gear 14 rotates. Since the inner diameter of the driving gear 13 is smaller than that of the driven gear 14, the driving gear 13 can save more effort when rotating, so that the stirring shaft 4 can better drive the stirring blade 5 to mix and stir the soil and the diluent. At the same time, the device uses water pressure as the power source for stirring, thereby greatly reducing the loss of electric energy, thereby greatly improving the energy saving performance of the device. After stirring evenly, the operator turns off the liquid pump 8 and starts the heating plate 19 to heat and dry the mixture of the diluent and the soil, so that the acetone and n-hexane inside the soil are quickly volatilized, and a dry soil matrix standard sample can be quickly obtained.
