The invention discloses mechanical material transmission equipment which comprises a mechanical main body and a decompression supporting frame. The end of the upper side of the mechanical main body isprovided with an object placing plate, the object placing plate is tightly welded to the mechanical main body, the lower side of the front end of the object placing plate is provided with an inclinedconveying table and a rolling rod, both the inclined conveying table and the rolling rod are arranged on the inner wall of the mechanical main body in a clamped and connected mode, and the left end and the right end of the inclined conveying table are provided with safety baffles. The two-layer design comprising the inclined conveying table and a built-in conveying layer is adopted for rapidly conveying materials, the simultaneously-conveyed material capacity is large, production efficiency is improved, materials can be conveyed in time, material supply is ensured, meanwhile, a dust collection layer is arranged on the surface of the inclined conveying table for collecting dust, garbage is sucked into a garbage guide-in channel and a garbage can through a garbage inlet, cleaning can be achieved without stopping the device, and therefore labor of workers is relieved.
