The utility model relates to the technical field of kitchen pretreatment, in particular to a waterproof sealing type speed reducer which comprises a speed reducer body, a rack and a main shaft and further comprises a sealing kit arranged between the speed reducer body and a cover plate at the tail end of a spiral conveyor. The sealing kit comprises a packing sealing seat, a packing gland, a packing, a sealing gasket, a rear sealing seat and a lip-shaped framework sealing gasket, the packing sealing seat and the rear sealing seat are installed at the two ends between the speed reducer and a tail end cover plate of the spiral conveyor respectively, and the main shaft is arranged in the packing sealing seat and the rear sealing seat in a penetrating mode. The packing is arranged between the packing sealing seat and the main shaft, the packing gland is installed on the packing sealing seat and used for pressing the packing, and the lip-shaped framework sealing gasket is arranged between the rear sealing seat and the main shaft. And kitchen sewage can be effectively prevented from entering the speed reducer.

The invention relates to a low-cost and high-precision unmanned aerial vehicle control surface integral forming method, and belongs to the technical field of advanced composite material manufacturing. According to the method, the core force bearing part of the control surface of the unmanned aerial vehicle breaks through the traditional step-by-step manufacturing mode of composite material forming and metal piece post-assembly, and integrated compression molding of the metal connecting piece and the composite material control surface is achieved. Through the technical means of precise positioning of the metal connecting piece, compression molding and forming integration of the composite material and the like, integrated forming of the metal connecting piece and the composite material is achieved, and the problem that traditional control surface manufacturing needs separate part manufacturing, machining and manual assembling is solved. The prepared unmanned aerial vehicle control surface has the advantages of being high in qualified rate, high in forming precision, high in production efficiency, low in cost, good in structural integrity and the like.

The application discloses a kind of titanium alloys, the titanium alloy is obtained by titanium alloy powder injection molding;Wherein, the titanium alloy powder includes: titanium alloy ball and TiB2 layer, polyamine layer, graphene oxide layer successively coated on the surface of titanium alloy ball, and the graphene oxide layer contains cerium element.The application also discloses a preparation method of the above-mentioned titanium alloy, comprising the following steps: taking titanium alloy powder and binder mixing, injection molding, degreasing, vacuum sintering at 1000-1100 DEG C for 2-3h, cooling to room temperature, solid solution at 700-720 DEG C for 40-60min, air cooling to room temperature, then heat preservation at 450-470 DEG C for 3-3.5h, and then air cooling to room temperature, to obtain titanium alloy.The titanium alloy has good strength while maintaining good toughness.
