The invention discloses a high-efficiency wood cutting machine and cutting method for construction engineering, which includes a hanger, a hoisting device, a positioning and clamping device, a side plate, a cutting device, a feeding device and a feeding device, and the feeding device Set on the right side, the feeding device is next to the left end of the feeding device and set on the lower side, a hoisting device is installed in the center of the hanger, and a positioning and clamping device is installed in the hoisting device. The wood in the feeding device is positioned, clamped and hoisted. The lower ends of the left and right side end plates of the hanger are fixed with horizontally arranged side plates and are located at the front end of the hoisting device. The side plates are equipped with left and right lateral movement The cutting device cuts the wood fixed in the positioning and clamping device, and the conveying device outputs the cut wood.

The invention discloses a self-consumption type simple heat preserving cover of a molten iron conveying tank and a use method of the self-consumption type simple heat preserving cover. The self-consumption type simple heat preserving cover is arranged on a container opening of a molten iron container. The heat preserving cover comprises a concave heat preserving assembly. The concave heat preserving assembly is a rotary body with an opening formed in the top, wherein the external diameter of the rotary body is gradually reduced from top to bottom, the concave heat preserving assembly is embedded into the container opening, and comprises an internally-hollow concave metal sheet box, a bottom leak hole is formed in the bottom face of the concave metal sheet box, inverted L-shaped tank opening supporting frames are symmetrically arranged on the end face of the edge of a box opening of the concave metal sheet box, the bottoms of the vertical sections of the tank opening supporting frames are connected with the upper end face of the concave metal sheet box, and the concave metal sheet box is filled with a heat preserving layer. The self-consumption type simple heat preserving cover hasthe advantages that the self-consumption type simple heat preserving cover is simple in structure, convenient to use and excellent in heat preserving performance, materials are cheap and easy to obtain, the cover body structure metal materials are online molten and recovered, molten iron slag is online modified with heat preserving material ash, and the acclimatation capacity is high.

The present invention relates to a method for preparing high-elasticity warm-keeping polyester composite yarn, which uses an oiling equipment, the oiling equipment includes a bottom plate, a mounting plate, an oiling device and a recovery box, and the above-mentioned oiling equipment is used to prepare high-elasticity warm-keeping polyester The specific process of the composite yarn is as follows: spun fiber forming, spun fiber oiling, spun fiber post-processing and winding molding, the oiling device includes a fixed rod, a rotating drum, an auxiliary mechanism, a driving mechanism, an oil storage cylinder, and an oiling sponge sleeve, oil suction column, sliding block, oil baffle, limit tube, connecting rod, moving rod and fixed ring. The invention uses the oiling device to cooperate with the existing traction equipment to complete the oiling work of the primary fiber. During the oiling process, the relative movement between the moving rod and the fixed ring drives the oil absorption column and the limit cylinder to stir the lubricating oil, and at the same time The bonding tightness between the primary fiber and the oiling sponge cover is increased through the auxiliary mechanism to improve the uniformity of oiling.
