The invention provides a cutting device for engineering construction, which relates to the field of construction equipment. The cutting device for construction of this project includes a base. The top of the base is welded with a top plate through two support rods. The bottom of the top plate is welded with an inner rod on the side far away from the support rods. Cutting sheets are arranged between the outer rods. The cutting device used in the project construction, the staff controls the lifting and lowering of the cutting blade through the gripping mechanism, and a shock-absorbing spring is arranged around the outer surface of the gripping rod. The vibration generated by the cutting device is transmitted to the outer surface through the motor box and the cross bar. On the cylinder, the shock-absorbing spring cushions and dissipates energy to reduce the strength when the vibration is transmitted to the handle. At the same time, a rubber sleeve is set on the outer surface of the handle, which greatly reduces the strength of the cutting vibration transmitted to the hands of the staff. , which solves the harm of cutting vibration to the body of the staff, and at the same time helps to reduce work fatigue and improve work efficiency.

The invention discloses a chemical injection, and particularly relates to a preparation method of a clindamycin phosphate injection. The clindamycin phosphate injection is prepared from the following raw materials in grams: clindamycin phosphate 300-400 g and sodium hydroxide 24.3-25.5 g. The preparation method comprises the following steps: dissolving 24.3-25.5g of sodium hydroxide in 1500-1900 g of water for injection, dissolving 300-400 g of clindamycin phosphate in the sodium hydroxide solution, stirring uniformly, adding water for injection to a constant volume of 2,000 mL, performing coarse filtering with a 0.65 mu m microporous filter membrane, performing fine filtering with a 0.22 mu m microporous filter membrane for sterilizing, and filling to obtain the clindamycin phosphate injection. The preparation method provided by the invention has the characteristics of applicability to mass production, high product yield, stable drug quality, and good therapeutic effect of drugs.

The invention discloses a novel ultrafine-powder packing machine, and relates to packaging equipment. A machine frame and a lifting column are arranged on a machine frame base, a weighing sensor is arranged on the lifting column, a clamping mechanism is further arranged at the upper end of the lifting column and is connected with a clamping air cylinder, a material stop valve and a dust removal pipeline, the material stop valve is further connected with a screw material cup, a filling screw is arranged inside a discharging hopper, a stirring motor is arranged inside a feeding hopper, a driven synchronous pulley is arranged above the feeding hopper, the driven synchronous pulley is connected with a driving synchronous pulley through a belt, and the driving synchronous pulley is connected with the filling motor. A lifting servo motor is arranged inside the machine frame and connected with a guide rod. The novel ultrafine-powder packing machine is high in production efficiency, and reasonable in design, has the functions of automatic quantification, automatic filling, automatic adjustment of metering errors and the like, is high in packing speed, is high in precision by the adoption of spiral discharging, and solves the problem that dust flies upward in a packing and filling process of ultrafine powder and materials having a great amount of dust.

The invention provides a cutting device for engineering construction and a using method, and relates to the field of construction instruments. The cutting device for engineering construction comprisesa base, a top plate is welded to the top of the base through two supporting rods, an inner rod is welded to the side, away from the supporting rods, of the bottom of the top plate, the bottom of theinner rod is sleeved with outer rods, and a cutting blade is arranged between the two outer rods. According to the cutting device for engineering construction, a worker controls lifting of the cuttingblade through a grabbing mechanism, a damping spring is arranged on the outer surface of a holding rod in a surrounding mode, vibration generated when the cutting device works is transmitted to an outer cylinder through a motor box and a transverse rod, the damping spring buffers and dissipates energy of the cutting device, and the strength of the vibration transmitted to the holding rod is reduced; meanwhile, the outer surface of the holding rod is sleeved with a rubber sleeve, so that the strength of cutting vibration transmitted to the hand of a worker is greatly reduced, the harm of the cutting vibration to the body of the worker is avoided, meanwhile, the working fatigue is reduced, and the working efficiency is improved.

The invention belongs to component and fittings in the field of architecture, and specifically relates to a fiber-reinforced exhaust duct. The fiber-reinforced exhaust duct is characterized by being made from the following raw materials of: by weight, 100 parts of portland cement, 5-10 parts of waste paper pulp fiber, 10-17 parts of asbestos fiber, 1-3 parts of a polypropylene substance and 1-1.2parts of a special-purpose auxiliary agent. By changing wastes into the main raw materials of the product, the invention is energy saving and environmentally friendly, and simultaneously is used to save a large amount of national resources and completely solve the problem of flying dust generated during the whole production process. In addition, a lot of machines are adopted to replace artisan craftsmanship, thus greatly improving the working environment for workers and mitigating their labor intensity.

The invention discloses a polishing device for marine metal castings, comprising: a frame, a shaping mechanism, a double-sided sand opening mechanism, a polishing mechanism, a detection mechanism for testing the polishing quality, a turning mechanism, a limit device and a control mechanism , the shaping mechanism is set at the front end of the frame, the double-sided sand-opening mechanism is set at the rear of the shaping mechanism, the polishing mechanism is set at the end of the double-sided sand-opening mechanism, the detection mechanism is set at the rear of the polishing mechanism, and the turning mechanism is set at the detection mechanism At the rear, the limit device is set on the corresponding workbench under the polishing mechanism, and the shaping mechanism, double-sided sand opening mechanism, polishing mechanism, detection mechanism, turning mechanism and limit device are all connected with the control mechanism. In the present invention, the casting is first reshaped by setting the shaping mechanism, and then the casting is sanded by the sand opening mechanism, and the casting after the sand opening is polished by the polishing mechanism, and a turning mechanism is also provided to allow it to be processed. The product is turned over, which greatly improves its work efficiency.
