In order to achieve the above object, the utility model provides a following technical scheme:

a freeze drying device for a soil sample comprises a drying bin, an equipment bin, a vacuum pipeline, a taking and placing door plate and a bearing frame plate;

the equipment bin is positioned below the drying bin, and the vacuum pipeline is arranged at the top of the drying bin and connected with external vacuum-pumping equipment; the taking and placing door plate is rotatably arranged on the front side of the drying bin and is used for taking and placing materials to be dried; the bearing frame plate is arranged inside the drying bin; a plurality of placing sliding frames are arranged on the inner wall of the drying bin; the bearing frame plates are erected on the placing sliding frame in a matching way;

furthermore, a perspective window is embedded in the picking and placing door plate and used for observing the internal bearing frame plate.

Further, a middle placing groove is formed in the middle of the bearing frame plate, and a test tube frame hole is formed in the bottom end of the middle placing groove.

Furthermore, the test tube rack holes are arranged and combined at equal intervals;

furthermore, a drawing groove and a side placing groove are also formed in the bearing frame plate;

compared with the prior art, the beneficial effects of the utility model are as follows:

adopt the utility model discloses, overall structure is succinct, and the cost is controllable, and the space in the dry storehouse of the effective reasonable utilization of multilayer formula bearing frame plate can carry out the dry operation of bulky, big soil sample in batches in the dry storehouse, and through the bearing frame plate of special structural design, the efficiency is got to the improvement to get through having the perspective window and put the door plant, the dry mass of real-time observation storehouse internal state guarantees the sample, has wholly improved the dry efficiency and the quality of soil sample.
