A spreading assembly is provided. The spreading assembly comprises a spreadable material container, a spreading mechanism, and a motor. The spreading mechanism is rotatably mounted to a bottom section of the material container and can disperse the spreadable material 360? around the spreading assembly. The motor is operatively connected to the spreading mechanism to engage same in rotation. The spreading assembly comprises a coupling assembly to engage the spreading assembly with an unmanned aerial vehicle (UAV) configured to transport the spreading assembly while it operates.

A surface treatment assembly for treating a contoured surface includes a surface treatment array formed from a plurality of base structures, each base structure operably coupled to a first phalange structure and a first phalange structure first end. A second phalange structure operatively coupled to each first phalange structure and a phalange joint disposed between each first phalange structure and each second phalange, thereby forming a finger structure. Moreover, at least one applicator head is coupled to a second phalange structure second end of each finger structure and configured to treat the contoured surface. A base structure actuator and a phalange joint actuator operatively coupled to and configured to manipulate the first phalange structure and the second phalange of each finger structure to adjust the surface treatment array relative to the contoured surface.

An oscillating sprinkler that includes a frame with a first boom and a second boom engaged therewith. The booms are oriented generally parallel to each other and each of the first and second booms rotates about an axis that extends along the boom's length of the respective first or second boom. The first and second booms rotate in opposite directions to each other and are synchronized so that they rotate toward each other or away from each other in unison. First and second booms are operatively engaged with gears that are driven by a water-powered motor. One or more valves may be provided to shut off or reduce water flow from one or both of the booms. The watering pattern from the booms is such that water tends to be more evenly distributed over a ground surface upon which the sprinkler is placed.

Provided is a dispensing device including a rotation drive part, a curved rail part connected to the rotation drive part in a first direction, a curved movement part coupled to a lower portion of the curved rail part, and a nozzle connected to the curved movement part, wherein the nozzle may pivot or rotate around a tip of the nozzle.

A nozzle head (1) for discharging a suspension which is under pressure and which includes a fluid and abrasive agent, with at least one nozzle (8) including at least one exit opening (20) for the exit of the suspension. The nozzle head (1) includes at least one first drive device (17), by way of which the nozzle head can be rotated about a first axis (A1).

The present disclosure relates to a fluid discharging assembly. The fluid discharging assembly includes a rotatable driving mechanism having at least two rotating eccentric shafts oppositely disposed about a center axis of the driving mechanism. The fluid discharging assembly includes a first slider having a first shaft hole coupled to a first of the at least two eccentric shafts and a second slider having a second shaft hole coupled to a second of the at least two eccentric shafts. The first slider includes a first through hole that receives a first fluid discharging pipe and the second slider includes a second through hole that receives a second fluid discharging pipe. The first fluid discharging pipe rotates at a first rotation by a rotation of the first slider and the second fluid discharging pipe rotates at a second rotation by a rotation of the second slider.

The present invention relates to the technological field of civil engineering, particularly to a dust reduction device for building engineering. The device includes a water tank with a controller and a booster pump, a driving mechanism enabling the device to cross obstacles, an adjustable spray mechanism with a mist intercepting mechanism, and an environment detection mechanism. The dust reduction device comprising the above components can move along the enclosure barrier to a target position for spraying according to real time requirements. The adjustable spray mechanism is configured in such a way that, when the wind force is between the specified minimum value and maximum value, and the wind direction is opposite to the spray direction, the mist intercepting mechanism is activated to avoid water mist blowing outside the construction site by wind and affecting the normal passage of pedestrians.

A fluid discharging assembly includes a gear set coupled to a first eccentric shaft and a second eccentric shaft oppositely disposed about the gear set, a first slider coupled to the first eccentric shaft such that the first slider rotates with the first eccentric shaft, a second slider coupled to the second eccentric shaft such that the second slider rotates with the second eccentric shaft, a first fluid discharging pipe coupled to the first slider and configured to rotate at a first rotation, and a second fluid discharging pipe coupled to the second slider and configured to rotate at a second rotation that is different from the first rotation.
