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 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. Through the arrangement of the limiting columns, it is conveniently ensured that the cover plate is stably installed on the box body, and chicks are prevented from escaping from the upper portion; through the arrangement of the sand bag, sand in the natural environment can be simulated, the chicks can be subjected to sand bath in the sand bag, and meanwhile the whole sand can be conveniently replaced; by arranging the adhesive tape, it can be guaranteed that the position of the sand bag is stable in the chicken sand bath process, meanwhile, the sand bag is convenient to replace, and the requirements for chicken sand bath habits and environments are met.
