The utility model relates to the technical field of livestock and poultry breeding, and discloses a sand bath device for livestock and poultry breeding, which comprises a base, a sand bath pool is movably mounted above the base, bumps are fixedly mounted above two ends of the base, short shafts positioned inside the bumps are fixedly mounted on two sides of the sand bath pool, and the short shafts are fixedly mounted on the base. A through groove is formed in the surface of the base. According to the sand bath device for livestock breeding, the base is pushed to a proper area, then a servo motor is started, at the moment, an arc-shaped spring releases elastic potential energy to pull an arc-shaped block to move in an arc-shaped groove, and therefore the sand bath pool inclines, sand in the sand bath pool is cleaned, and compared with a traditional sand bath device for livestock breeding, the sand bath device for livestock breeding is convenient to use. According to the sand bath device for livestock and poultry breeding, the base is pushed to a proper area after passing, the sand bath pool inclines to pour sand, the sand replacement speed is increased, and use is convenient.

The utility model discloses constructional engineering geotechnical density detection equipment which comprises a sand bath bed for constructional engineering geotechnical density detection, a bearing part is arranged on one side of the sand bath bed, and the bearing part is used for placing a pycnometer for geotechnical density detection; the sand bath bed is provided with a lifting part on one side of the bearing part, and the lifting part is used for being connected with the bearing part to move the pycnometer out of the sand bath or move the pycnometer out of the sand bath. According to the utility model, the pycnometer is moved in and out through the arranged lifting piece, so that the opportunity that an operator is in direct contact with a high-temperature soil sample is reduced, the risk of scalding is reduced, and the safety of operation is improved. The lifting motor is matched with the connecting rod, so that automatic lifting of the pycnometer is realized, the pycnometer can be quickly moved out of a sand bath, manual operation is reduced, and the efficiency of geotechnical density detection is improved.

The present application relates to the technical field of soil organic matter determination experiment, in particular to a sand bath device for heating soil organic matter in multiple zones, aiming at solving the problem of uneven temperature in sand bath heating. It comprises a heating disc, a plurality of detection zones are formed on the heating disc, and a base is fixedly connected to the center of each detection zone; a closed box is detachably connected to the base, a plurality of closed boxes are arranged around the base to form heating units, gaps exist between adjacent heating units and the inner side wall of the heating unit and the adjacent heating disc to form heating spaces, and a containing cavity is formed in the closed box; a heat preservation cover is detachably connected to the top of the heating disc; sand particles are filled in the containing cavity and the heating space, and the heating unit can rotate along the base. The heating disc is divided into a plurality of detection zones, realizing partition and modular heating, the closed box forms a heating unit around the base and can rotate along the base, and the sand particles can be made to move relatively after heating by rotating, so that the solid sand particles are mixed uniformly after heating.

The utility model discloses a sand bath device for raising chickens, which relates to the technical field of sand bath for raising chickens and comprises a box body, a sealing door arranged on one side of the box body, a mounting frame arranged on the other side of the box body, a cover plate sleeved on the top end face of the box body, a plurality of ventilation openings equidistantly arranged on the cover plate, a sand bag arranged on the inner wall of the bottom of the box body, and an adhesive tape arranged on the sand bag and used for fixing.
