The invention relates to a water-fertilizer-pesticide integrated irrigation system. The water-fertilizer-pesticide integrated irrigation system comprises a water-fertilizer-pesticide integrated operation platform, a drawing device, a circuit system, a spray irrigation system, a spraying system and a water-fertilizer-pesticide automated control system, wherein the water-fertilizer-pesticide integrated operation platform comprises a mobile high frame, a hanging and lifting system, a spraying rod, a water spray head and a mist spray head; the drawing device comprises a hollow square-shaped steel rope, a fixed lantern ring, a groove wheel, a driving wheel and a steel rope driving motor; the spray irrigation system comprises a submersible pump, a main water conveying pipeline, branch pipelines and the like; the spraying system comprises a spraying vehicle frame, as well as a pesticide liquid box, a roller pump, a roller pump motor, a pesticide conveying pipe and a pesticide conveying pipe coil which are mounted on the spraying vehicle frame; and the water-fertilizer-pesticide intelligent control system comprises a programmable logic controller, a water pressure sensor and the like. The water-fertilizer-pesticide integrated irrigation system disclosed by the invention combines water-fertilizer management, plant protection and pesticide application together by creating the water-fertilizer-pesticide integrated operation platform, and three functions of irrigation, fertilizer application and pesticide spraying can be realized through one set of equipment, so that the management links are reduced and the working efficiency is improved.

The invention relates to an air-assisted wide plant protection unmanned helicopter and an operation method implemented by the same. The air-assisted wide plant protection unmanned helicopter comprises an air-assisted air duct device, a support frame, a storage battery, an electric diaphragm pump, a chemical tank and a foldable spray rod. The air-assisted air duct device, the support frame, the storage battery, the electric diaphragm pump, the chemical tank and the foldable spray rod are mounted on an unmanned helicopter, spray nozzles are distributed on the foldable spray rod, the foldable spray rod is divided into a middle main spray rod, first spray rods and second spray rods, and the first spray rods and the second spray rods are arranged on the two sides of the foldable spray rod. Downwash airflow formed by the unmanned helicopter is accelerated by the aid of conical pipeline structures, and high-speed airflow flows through vertical flat columnar air pipes and then flows into horizontal flat tapered air pipes; an air curtain is formed on the spray rods in the width direction of the spray rods by the high-speed airflow, the air speed of the air curtain is downwardly uniformly distributed, accelerating, carrying and secondary atomizing effects can be realized for fog-drops by the air curtain, and the fog-drops are atomized by the spray nozzles. The air-assisted wide plant protection unmanned helicopter and the operation method have the advantages that the working widths of the spray rods are increased, so that the chemical application rate can be increased under the condition that the chemical liquid carrying amount of the unmanned helicopter is unchanged, the operation time can be shortened, the chemical application efficiency can be improved, and power consumption of the unmanned helicopter can be reduced.

The present invention provides a roller for a fibre-processing machine, for example a spinning preparation machine such as a flat card, cleaner or the like, flock feeder, roller card, nonwoven-forming machine or the like, comprises a roller body. In order to make possible, by simple means, economical manufacture and adequate dimensional stability, for example a substantially constant carding nip,the roller body has at least one metal cylinder and at least one circular cylindrical sheath of fibre-reinforced plastics material surrounding the cylinder.

The reel-type automatic cleaning and mopping machine includes a mop, a stirring mechanism, a car body, a rotating device, a lifting device, a translation mechanism, and a transfer device. The handkerchief strips are connected under the base sheet. There are slides on both sides of the board frame of the mop, and the substrate is inserted into the slides. The agitating washing mechanism is equipped with a runner, a swivel ring, a swivel ring sleeve, and an agitating washing plate. A slideway is arranged on the outer circle of the runner. Hanging cards and push cards are installed on the swivel. Two sets of agitating and washing mechanisms are alternately docked with the end of the mopping handkerchief, pull out the dirty substrate handkerchief in the plate frame, and insert the cleaned substrate handkerchief. When cleaning, hang the card to pull the dirty mopping handkerchief into the runner slideway, the runner is reversing, and the stirring plate stirs and washes the handkerchief. The stirring and washing plate is retracted, and the runner rotates quickly to dehydrate. After the cleaning is finished, the swivel is reversed and the substrate is inserted into the rack slideway. Return the mop to its original position and continue wiping the floor. Can automatically clean mopping and dehydration. It is suitable for quick scrubbing in stations, subways, tunnels, squares, and public places, improving work efficiency and cleaning quality.

Reel front cleaning and mopping machine, including telescopic arm, mop, broom handle lifting mechanism, cleaning mechanism, tank shell mechanism, and car body. Two cleaning mechanisms are installed horizontally in front of the car body, and two groups of mopping handkerchiefs are installed below the cleaning mechanism, and each group has two rows of mopping handkerchiefs. A rotating wheel, a swivel ring, a swivel ring sleeve and a stirring washing plate are installed in the stirring washing shell of the cleaning mechanism. Hanging cards and push cards are installed on the swivel. The handkerchief strips are connected under the base sheet. There are slides on both sides of the plate frame of the mop and the outer circle of the runner, and the substrate is inserted into the slides. Front and rear mopping handcarts take turns mopping and cleaning. The hanger on the swivel pulls the dirty mopping base sheet out of the slideway of the mopping rack and into the runner slideway in the agitating shell. The rotary ring stirs and dehydrates the handkerchief strips in the stirring shell, and then the rotary ring reverses to insert the clean substrate into the rack again. Because the mopping handkerchief is cleaned with the vehicle, the mopping floor is cleaner, the width of the mopping floor can be increased, and the work efficiency is greatly improved. It is suitable for quick scrubbing in stations, subways, tunnels, squares, and public places.
