The application relates to a force couple balance and longitudinal array push-pull vertical take-off and landing high-speed aircraft, belonging to the technical field of aircrafts, which comprises a fuselage, a rotor, a fixed wing, a steering controller and a propeller. The rotor is installed at the top of the middle part of the fuselage through a rotor shaft, and a clutch is arranged between the rotor and a power system and / or a transmission system matched with the fuselage, so as to be controlled to be disconnected or to transmit power to the rotor. The steering controller comprises a fixed base and a rotating base, and each of the nose and the tail has a set of the rotating base. The propeller is provided with two propellers which are respectively installed on the rotating bases of the nose and the tail, and are controlled to rotate with the rotating bases relative to the fixed base. The force couple formed by the front and rear thrust vectors is used to balance the reverse torque brought by the rotor. When the propeller is coaxial with the middle axis of the fuselage, the wind area of the single propeller obtains double thrust. The application can improve the energy utilization rate, improve the carrying capacity, improve the flight safety performance and obtain a longer hovering time.

The utility model discloses a spraying system of a spraying tower, which relates to the waste gas treatment technology, and adopts the technical scheme that the spraying system comprises a tower body, a spraying pipe and a nozzle, the spraying pipe comprises a main pipe and a branch pipe, the nozzle is rotatably connected to the branch pipe, a rotating piece is arranged in the nozzle, and the nozzle is provided with an atomizing opening and a liquid flow opening. The spray head starts to rotate under the action of the rotating part, the treatment liquid in the spray head is sprayed out from the atomization opening and the liquid flow opening under the action of liquid pressure, the treatment liquid sprayed out from the liquid flow opening is large in particle diameter and can effectively combine pollutants with large diameters in waste gas, the treatment liquid sprayed out from the atomization opening is small in particle diameter, and the pollutants can be effectively combined with the pollutants with large diameters in the waste gas. The spray tower is simple in structure, large in dispersion area and longer in hang time, and can be fully combined with pollutants with smaller diameters in waste gas, and meanwhile, as the rotation of the spray head can provide centrifugal force for the treatment liquid leaving the spray head, the treatment liquid sprayed out of the atomization port and the liquid flow port can have wider coverage area, and the working efficiency of the spray tower is improved.

The invention belongs to the technical field of food production and processing, and particularly relates to a precise powder batching device for food production and processing, which comprises a stirring barrel, a sealing cover is mounted at the top of the stirring barrel, a feed hopper communicated with an inner cavity of the stirring barrel is embedded in the top of the sealing cover, a discharge pipe is arranged right below the bottom end of the stirring barrel, and the discharge pipe is connected with the stirring barrel. Supporting plates which are connected with each other are fixedly connected to one side, opposite to the discharging pipe, of the bottom end of the stirring barrel; a stirring mechanism for stirring powder is arranged in the stirring barrel, the stirring mechanism comprises a first motor fixedly mounted at the top of the sealing cover, and the bottom end of an output shaft of the first motor penetrates through the stirring barrel and is fixedly connected with a rotating rod. Furthermore, the effects of further prolonging the powder mixing time and the mutual collision diffusion frequency of different powder materials are achieved, so that the powder materials which are continuously flapped, impacted and rotationally raised are mixed more uniformly.
