This utility model relates to the field of work machinery technology, and discloses an air conditioning assembly and work machinery. The air conditioning assembly includes: an evaporator having an air inlet and a first air outlet; and a first duct assembly including a face-blowing duct, a defrosting duct, and a first common duct. One end of the first common duct is connected to the first air outlet, and the other end is connected to the face-blowing duct and the defrosting duct, respectively. In this utility model, the face-blowing duct and the defrosting duct are connected to the first air outlet of the evaporator through the first common duct. Compared with the original independent duct, the first common duct has a larger flow cross-sectional area. Under the same air volume at the first air outlet, the air velocity in the first common duct is lower, thus effectively reducing the eddy current intensity in the first common duct, thereby reducing the air pressure loss during the air guiding process of the first duct assembly, increasing the air velocity at the air outlets of the face-blowing duct and the defrosting duct, so that the air conditioning assembly has a better air outlet effect under the same working power.

The invention discloses a total temperature probe with an efficient particulate matter taking-out structure and a flow channel optimization method of the total temperature probe, belongs to the technical field of total temperature probes, and solves the problem that the measurement precision is affected due to the fact that an existing total temperature probe cannot discharge particulate matter in time. The device comprises a support shell, a socket and a head shell, wherein a throat, a concave surface channel and a sweepback sensitive channel are arranged in the head shell, the throat and the concave surface channel are communicated with each other, and the sweepback sensitive channel is located at the bottom between the throat and the concave surface channel. Through the arrangement of the throat channel, the concave channel and the sweepback sensitive channel, water drops, ice, ice crystals, dust and other particles contained in air enter the flow channel and then are guided out of the straight outlet through airflow inertia, the situation that the total temperature measurement precision and reliability are reduced due to channel blockage caused by particle deposition is prevented, and the flight safety of an aircraft is improved.

The utility model provides a foldable trailing edge flying wing unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles, the foldable trailing edge flying wing unmanned aerial vehicle comprises a main wing, the main wing comprises a main wing inner section and a main wing outer section, the wingtip of the main wing outer section is connected with a small wing, and the trailing edge of the main wing outer section is connected with a connecting wing and an empennage; the winglet is connected with the connecting wing through a driving rotating shaft, the connecting wing is connected with the empennage through a driven hinge, and the empennage is connected with the main wing inner section through a driven hinge; and the front parts of the connecting wing and the empennage are connected with the main wing outer section through a locking structure. When the multi-wing unmanned aerial vehicle is used for executing complex maneuvering actions such as emergency avoidance, large-attack-angle climbing and small-radius turning, the winglet, the connecting wing and the empennage are folded under the driving of the wingtip driving rotating shaft, so that a connecting wing layout is formed. The wing surfaces are converted into a three-dimensional structure from the same plane, so that an additional stabilizing plane is added for the flying wing unmanned aerial vehicle, and meanwhile, additional torque is provided for the unmanned aerial vehicle to execute complex maneuvering actions.

This utility model relates to the field of ink dispersion cylinders, and provides a cylinder for weakening vortex ink dispersion. It includes a cylinder body, a rotating hinge fixedly connected to the top of the cylinder body, an opening / closing cover rotatably connected to the bottom of the rotating hinge, and a handle fixedly connected to the top of the opening / closing cover. The cylinder body is equipped with a vortex-weakening device. This utility model uses a motor to provide power, working in conjunction with paddles and counter-rotating inclined blades. The layered design and the counter-rotating angle design of the stirring blades effectively counteract the centripetal force of the vortex formed when the ink rotates, significantly reducing the vortex intensity and preventing the ink from becoming locally aggregated or unevenly dispersed due to the vortex. The multi-stage stirring components cover different height areas within the cylinder, expanding the stirring range and ensuring that the ink is sufficiently disturbed both radially and axially, ensuring more uniform mixing of pigment particles and base material. This technical solution solves the technical problem of weakening and reducing vortexes in existing technologies.

A low-resistance powder concentrator rotor structure, a rotor upper cover plate, a rotor middle plate and a rotor lower cover plate are arranged from top to bottom on the outside of a rotor shaft sleeve and a rotor cone, the rotor upper cover plate and the rotor middle plate are connected with the rotor shaft sleeve or the rotor cone through a rotor connecting plate, and the rotor lower cover plate is directly connected with the rotor cone; a plurality of inclined grooves are formed on the rotor upper cover plate and the rotor middle plate; the rotor connecting plates are arranged in pairs, have the same shape and are symmetrical about the rotor axis; the shapes of the adjacent two rotor connecting plates are different, the included angles with the horizontal plane are different, and the rotor connecting plates are arranged in the form of vertical plates, so that the high-speed airflow in the rotor cage is hindered and scattered. The present application interferes with the generation of the resistance surface of the connecting part position by the special connecting plate and vertical rod arrangement, so that the number of the connecting parts in the same plane or cone surface is small, the ventilation cross-sectional area is increased, and the power consumption of the vertical mill system fan is reduced.
