Provided is a frozen commodity distribution method reduced in labor and cost while holding the quality of frozen commodities and a cold insulation container unfoldable and foldable in a short time while providing high cold insulation performance. In the distribution method, the frozen commodities requiring cold insulation are stored in the cold insulation container formed of a vacuum thermal insulation material, and the cold insulation container is distributed by a refrigerator car, cold insulation car, or a room temperature car other than a chill car. In the foldable cold insulation container, each of peripheral wall parts, cover parts, and bottom face parts is formed by including the vacuum thermal insulation material in a sheet material, and the peripheral wall parts of the cover parts adjacent to the continuously arranged peripheral wall parts are foldable since the vacuum thermal insulation material is divided along pleat lines. When the container is used, the cover parts and the bottom face parts are rotated in closed attitudes to form into a box. When the container is not used, the bottom face parts are bent to the inside or outside of the peripheral wall parts, the cover parts are bent in the reverse direction of the bottom face parts, and the peripheral wall parts are allowed to approach each other while bending the peripheral wall parts inward along the pleat lines, stacked on each other, and folded.

The method is simple in process, reduces infrastructure cost, facilitates the operational management, and is suitable for the underdeveloped towns and rural areas.

The invention discloses a fuel gas theftproof ball valve. The fuel gas theftproof ball valve comprises a ball valve, a valve deck and a valve element, wherein the valve element is connected with a wrench through a valve rod; the valve rod is located in a filler bin arranged on one side of the valve body; a limiting baffle tongue is which is used for limiting the range of a rotation angle of the wrench is formed on the wrench; a locking screw of which the head part is provided with a triangular-prism-shaped or four-petal-plum-column-shaped screwing structure is arranged between the limiting baffle tongue and the outer wall of the filler bin; the locking screw is used for locking the wrench through the outer wall of the filler bin; and when the locking screw is only separated from the outerwall of the filler bin or the limiting baffle tongue, the wrench is unlocked. The fuel gas theftproof ball valve has the beneficial effects that the locking screw can only be screwed by a special opening tool, so that the valve is prevented from being opened by misoperation or being opened arbitrarily, and use safety by a user is ensured; besides, the opening tool is small in structure size and isconvenient to carry; locking and unlocking operation is convenient and requires small force; the service life is long; and hidden danger that the locking screw is lost is avoided.

A combine harvester (10) comprising fan apparatus (26) for generating an air stream through cleaning apparatus (24) to separate chaff from grain is provided. The fan apparatus comprises a plurality of fan modules (35) for generating mutually spaced air sub-streams. The cleaning apparatus comprises an auxiliary air intake located between two adjacent air sub-streams, and means (52) to narrow the passage for each air sub-stream adjacent the auxiliary air intake (50). The narrowing serves to create a region of lower pressure (L) due to the venturi effect. The low pressure region draws air directly from the environment into the air stream through the auxiliary air intake thereby reducing the transverse component of the sub-streams and providing a more uniform air flow through the cleaning apparatus.
