PURPOSE: A portable vacuum-packer for a soil core sample is provided to prevent the property of soil from being varied by the evaporation of moisture, thereby accurately analyzing the soil. CONSTITUTION: A portable vacuum-packer (10) for a soil core sample includes a body (100), a vacuum bonding unit (200), and multiple supporting members. A packing pack housing the sample inside is mounted on a sample mounting groove at the upper side of the body. The vacuum bonding unit is mounted on a mounting part with a sliding mode, and the mounting pat is separated from the sample mounting groove at a certain distance. One end of the supporting member is hinged at the lower side of the body. The supporting member separates the body from the ground at a certain distance, and supports the body. The vacuum bonding unit includes a supporting plate part, a vacuum generating part, a thermal bonding part, and a packing pack fixing part. Guide grooves are respectively and longitudinally formed at both sides of the supporting plate part. The vacuum generating part at one side of the upper side of the supporting plate part maintains a vacuum condition with discharging air inside the packing pack to outside. The thermal bonding part at the other side of the upper side of the supporting plate part thermally bonds and seals the packing pack of which the vacuum condition is maintained by the vacuum generating part. The packing pack fixing part maintains the position of the packing pack with fixing the opening of the packing pack. |
