The invention discloses a use method of a stone cutting device applicable to field paving and pasting construction. The stone cutting device comprises a housing, wherein a handle is arranged at one side of the housing; an annular assistant handle is arranged on the handle; a controller is arranged on the top part of the housing; a first cylinder is arranged at the inner sidewall of the housing, and a first telescoping rod is connected to the end part of the first cylinder; a limiting plate consisting of an upper limiting plate and a lower limiting plate is arranged at one end of the first telescoping rod; and the first telescoping rod and the upper limiting plate are of an integral structure. According to the stone cutting device, a cutter is composed of a plurality of groups of small cutter heads of which the positions can be adjusted, and moreover, the quantity of the small cutter heads can be increased or decreased so as to adaptively cut small quadrate empty chambers with differentsizes or empty chambers with other shapes and different sizes; and meanwhile, the position of a cutter base is limited through the upper limiting plate and the lower limiting plate, and the cutter base is locked through a locking nut, so that the stone cutting stability of the cutting device is ensured.

The invention discloses a pipeline joint device, which includes a pipeline joint connection part, a fitting body, a sealing ring and a pipe body, an annular groove is arranged on the fitting body, and a groove with a leading edge is arranged at the bottom of the upper ring groove of the fitting body Groove, the groove is engaged with the PE liner, the bottom of the PE liner is provided with a viewing hole, the inner wall of the front part of the PE liner is provided with an arrow-shaped groove, and the inner wall of the bottom of the crimping copper ring is provided with a ring groove, and the PE liner is connected with the press Connect the purple tube ring socket, because the bottom of the upper ring groove of the sleeve of the invention is provided with a groove with a front edge, the groove is engaged with the PE gasket, the inner wall of the PE gasket is provided with an arrow-shaped groove, and the copper ring is crimped. The inner wall is provided with a ring groove, and the crimped copper ring is embedded in the PE liner to fix the crimped copper ring, and the crimped copper ring will not be displaced during construction.

The invention relates to a full automatic steam food boiling device, comprising a material boiler, a steam generator, a water tank, a valve, a water pipe and material suppliers; each material supplier comprises a material storeroom, a supplying control mechanism and a material pipe; the material storerooms of all the material suppliers are connected with a charging port by the material pipes; the supplying control mechanisms are arranged on the material pipes between the material storerooms and the charging port; the water tank, the steam generator and the lower part of the material boiler are sequentially connected by the water pipe. The upper part of the material boiler is connected with the upper part of the water tank by the water pipe; the valve is arranged on the water pipe between the water tank and the steam generator. Materials are directly boiled by adopting high temperature steam, the utilization rate of the steam is high and a greater energy-saving effect is realized; the high temperature steam is input from the lower end and achieves a stirring action, so the materials are more uniformly heated, the heat transfer is accelerated, the boiling time is shortened and the food boiling device is suitable for the fast food industry; the steam is collected into the water tank for reuse instead of being directly discharged to avoid air pollution and greater environment-friendly and sanitary effects are achieved.
