The present invention relates to a gas turbine. According to the present invention, gas may be injected in the circumferential direction in order to rotate the turbine shaft using a repulsive force, thereby improving the efficiency of the conversion of rotational energy of the turbine and reducing manufacturing costs. Also, the flow resistance to the gas may be reduced, pressure leakage may be prevented, and energy loss may be reduced so as to manufacture an inexpensive turbine having high efficiency. In addition, when turbines having capacities different from each other are manufactured, parts may be easily shared with each other, and the eccentric rotation of the turbine shaft may be prevented to significantly improve durability. Also, an air compression part, a gas expansion part, and a power generation part may be modularized, and fuel and water may be supplied together. Thus, overheating of the gas expansion part may be prevented to prevent air from being excessively expanded, and vapor may be generated to improve rotational force in addition to the impellent power of the turbine. Also, the gas turbine may be manufactured using a relatively inexpensive metal material instead of expensive high temperature ablative materials in order to reduce manufacturing costs.

The invention discloses a multifunctional interactive robot. The multifunctional interactive robot comprises a robot body and two projection mechanisms located at the eye parts of the robot body. Eachprojection mechanism is mounted at the corresponding eye part of the robot, and the projection angle is controlled by a servo steering machine, so that the rich projection combination is achieved, for example, two images are spliced together to form an ultra-wide picture, or the two images are projected separately to form different pictures, more information is fed back to a user, enjoyment is high, and playability is high.

The invention belongs to the technical field of drilling tools in machining and relates to a chip breaking structure of a reducing position cutting edge of a stepped drill. The chip breaking structureis composed of a step reducing position cutting edge, a chip breaking cutter face, a chip breaking edge, a stop face, an edge strip, a chip discharging groove and a step back section end face. According to the chip breaking structure, traditional continuous spiral edge cutting is changed into step edge joint cutting, arc front cutter faces are changed into straight cutter faces mutually forming an angle, and a chip breaking space is formed. The front cutter faces mutually forming the angle enable cutting chips to bend and undergo torsional deformation, the stress of the cutting chips is increased, the breaking strength of the cutting chips is easier to reach, and therefore metal chip breaking and chip smashing are effectively achieved. The scratches, caused by continuous cutting chips, ofa hole wall are restrained, and cutter rotation deviation caused by twining of the cutting chips is reduced. The chip breaking structure facilitates to greatly improve the hole forming quality of thestep drill, reduces the machining cost and has good engineering application prospect.

The invention relates to a hub motor comprising a stator unit, a rotor unit, a magnetic ring and a sensing circuit unit. The rotor unit is provided with a shaft part which can be relatively and rotatably penetrates through the stator unit; the magnetic ring and the sensing circuit unit are arranged on the rotor unit and the stator unit respectively and are correspondingly positioned at intervals between the rotor unit and the stator unit; and the magnetic ring is provided with a first ring piece extending radially and a second ring piece which is connected with the first ring piece and extends axially. With the structural design of the magnetic ring, the problems of eccentric rotation and axial displacement generated in the process that the magnetic ring rotates with the rotor unit can be avoided; and as the magnetic ring and the sensing circuit unit are arranged between the rotor unit and the stator unit and are wrapped and fixed by both the rotor unit and the stator unit, on the one hand, the structure stability that the magnetic ring is combined with the rotor unit is increased so as to resist the centrifugal force generated by high speed rotation, and on the other hand, the magnetic ring can be prevented from being polluted and interfered by the outside, and the cost for additional arrangement of an outer cover is saved.

The invention discloses a loader hopper used for concrete mixing and relates to the technical field of concrete loaders. The invention includes a hopper and a stirring shaft, the hopper is connected to the stirring shaft in rotation, and the stirring shaft passes through the hopper; the invention avoids eccentric rotation when rotating under high load by using a central gear and a planetary gear, and improves the service life of the rotating shaft The present invention is by using mounting frame, stirring frame and adapter block, and this structure adopts multiple mounting frames, connects some spiral type stirring frames between mounting frames simultaneously, increases the quantity of stirring frame compared with traditional mixing hopper, simultaneously The length of the stirring frame is shortened, so that the stirring frame has better impact resistance during stirring, and if the stirring frame is impacted by an external force, the adapter block can be squeezed, and then the adapter block can slide in the installation groove for a certain distance to relieve pressure and protect Stirrer; by using a slide and a spring, the slide can cushion the impact of the stirrer and fastening screws to protect the stirrer.
