The utility model discloses a silkworm egg hatching system, including the independent placement of hatching box in silkworm room, every hatching box is equipped with the vertical branch pipe, and the bottom of arbitrary branch pipe is closed and the upper end is through hatching box, and the upper end of branch pipe is communicated to the water vapor supply main pipe in the upper side, and the valve seat is axially spaced and is located in the side of hatching box, and the hatching frame is movably placed in hatching box, the position valve seat position of hatching frame one to one corresponds, and after being placed in hatching box, the valve seat is opened to the inside top, to directly supply the water vapor of the hatching frame of being placed. The utility model discloses the hatching box is independent and relatively closed to silkworm room, so the water vapor in the inside is less influenced by the outside, and when the hatching seat is placed in hatching box, can quickly carry out water vapor supplement, even when single hatching seat is taken out, basically will not influence the water vapor stability of the rest hatching frame in the hatching box, and the whole system can easily control the water vapor in every hatching box, and the stability is higher.

This invention relates to the field of precision drive and positioning technology, and discloses a three-dimensional macro-micro composite positioning stage, which includes a stage body, an X-axis motion component, a Y-axis motion component, a Z-axis motion component, and a mobile terminal platform connected to the X-axis motion component, Y-axis motion component, and Z-axis motion component respectively. The X-axis motion component includes an X-axis macro-drive and an X-axis micro-drive; the Y-axis motion component includes a Y-axis macro-drive and a Y-axis micro-drive; the Z-axis motion component includes a Z-axis macro-drive and a Z-axis micro-drive, used to jointly drive the mobile terminal platform to linear motion along the X-axis, Y-axis, and Z-axis. This invention balances large stroke and high precision, achieving three-dimensional positioning with millimeter-level stroke and nanometer-level precision. The X-axis, Y-axis, and Z-axis micro-drives use piezoelectric ceramic direct drive, resulting in high positioning accuracy and fast response speed. The overall structure of this invention is reasonable and compact, and its operation is reliable.
