This utility model discloses an electric vertical takeoff and landing manned aircraft, including an aluminum alloy frame, a vibration damping assembly, a right guardrail connected to one side of the aluminum alloy frame, and a left guardrail connected to the other side via a pivot seat. The vibration damping assembly includes a first carbon fiber tube and a vibration damping seat fitted on the first carbon fiber tube. The upper and lower vibration damping seats are fastened with bolts through the penetration between the first carbon fiber tube and the aluminum alloy frame. The rubber vibration damping pad absorbs high-frequency vibration energy through its own elastic deformation, effectively blocking the direct transmission of vibration to the frame. The axial anti-roll bracket forms an elastic clamp on the sleeve through rubber clips. This clamping force can be flexibly adjusted by the hardness of the rubber clips, which greatly reduces the vibration felt in the cockpit area. Both the first and second carbon fiber tubes are made of carbon fiber composite material, which has a weak ability to reflect sound waves and can reduce the transmission efficiency of propeller aerodynamic noise.

The utility model relates to the technical field of sludge dewatering treatment, and discloses a sludge dewatering treatment device convenient for feeding, which comprises a box body, a treatment shell is fixedly mounted on the upper surface of the box body, a feeding pipe is fixedly mounted on the upper surface of the treatment shell, and a feeding pipe is fixedly mounted on the upper surface of the feeding pipe. A cleaning mechanism is arranged on the outer side of the box body, and a promoting mechanism is arranged on the outer side of the box body. According to the sludge dewatering treatment device convenient to feed, a motor is started to drive a rotating shaft to rotate, so that a mounting block on a connecting rod is matched with rotation of a spiral auger, sludge is conveniently moved downwards to enter a box body, meanwhile, a cleaning block on the mounting block is in contact with the inner wall of a treatment shell, and the cleaning block scratches adhered impurities; and meanwhile, a movable block moves on the cambered surface of a straight rod to extrude a reset spring, so that a cleaning block has a better cleaning effect on impurities on the inner wall of the treatment shell in a reciprocating motion process, and it is guaranteed that the impurities on the inner wall of the treatment shell enter and exit from the interior of the box body.

The utility model discloses an oiling agent atomizing device of non-woven fabric hot air equipment, which relates to the technical field of non-woven fabrics and comprises an atomizing working bin, the top of the atomizing working bin is fixedly connected with a first one-way motor, an output rotating shaft of the first one-way motor is fixedly connected with a first linkage rod, and one end of the first linkage rod is rotatably connected with one end of a second linkage rod. The other end of the second linkage rod is rotationally connected with the top of a linkage swing rod, the bottom of the linkage swing rod is fixedly connected with a liquid passing pipeline, the bottom of the liquid passing pipeline is fixedly connected with an atomization opening, and the liquid passing pipeline is fixedly connected with an atomization controller through a liquid passing hose. According to the non-woven fabric spraying device, through the arrangement of the atomization working bin, the first one-way motor, the first linkage rod, the second linkage rod, a linkage swing rod, a liquid passing pipeline, an atomization opening, a liquid passing hose, an atomization controller and an oil inlet pipe, the effect of flexibly changing the spraying area can be effectively achieved, the non-woven fabric spraying device can adapt to non-woven fabrics with different widths, and the practical effect of the non-woven fabric spraying device is greatly improved.
