Further technical scheme is, described magnetron has 12 at least, is installed in respectively on three lateral walls placing the chamber, and four magnetrons are installed on each lateral wall.
Further technical scheme is, described weighing frame is by at least one tressel layering, and tressel is provided with the PP box.
Further technical scheme is, the top of described stainless steel casing is provided with the air draft frame, is provided with exhaust fan in the air draft frame, and the air draft frame is connected with moisture exhausting port.
Further technical scheme is, described stainless steel casing is of a size of 820*750*1400mm.
Further technical scheme is, the power supply on the described power bay also arranges external power supply plug.
Utilize this soil sample water percentage fast detecting instrument to detect the method for soil sample water percentage, may further comprise the steps:
-be placed in placement the soil sample taking-up indoor;
-by automatic weighing device to placing indoor soil sample and the weighing frame is weighed and record together;
-weigh to close after finishing and place the chamber, utilize infrared lamp that soil sample is carried out the light wave heating earlier, utilizing magnetron that soil sample is carried out microwave heating;
-treat that moisture in the soil sample is toasted out after, the recycling automatic weighing device is to placing indoor soil sample and the weighing frame is weighed and record together;
-calculate water percentage in the soil sample by the recording gauge of weighing before and after the baking.
Compared with prior art, the invention has the beneficial effects as follows: the present invention can be transported to the scene, can detect immediately after soil sample is removed, and avoids external when transportation moisture factor such as lost naturally to the influence of detection accuracy; Because baking is to adopt microwave mode, is heated simultaneously inside and outside the soil sample, has shortened whole stoving time greatly, saves haulage time simultaneously, has obviously avoided the influence to whole project progress; What the present invention adopted is that the mode of microwave heats behind the first light wave, and the explosion phenomenon in the time of effectively having prevented the soil sample heating guarantees the complete of soil sample, has improved detection accuracy and security.
