Material conveyer without conveying blade

The utility model relates to a material conveyer without a conveying blade. The material conveyer without the conveying blade comprises a material conveying device, a driving device connected with the material conveying device and a material bin arranged at the upper end of the material conveying device. The material conveying device comprises a feed port, a discharge port, a tubular material conveying pipe and a conical material conveying pipe, wherein the tubular material conveying pipe is connected with the driving device, material conveying blades are installed in the tubular material conveying pipe, no conveying blade is arranged in the conical material conveying pipe, and the diameter of the conical material conveying pipe becomes larger gradually in the feeding direction of materials. The feed port is formed in the upper portion of the end, close to the driving device, of the tubular material conveying pipe and is connected with the material bin. The discharge port is formed in the tail end of the conical material conveying pipe. According to the material conveyer without the conveying blade, due to the fact that the conical material conveying pipe becoming thicker gradually is arranged in the feeding direction of the materials, the resistance can be reduced during material conveyance, and resistance superposition is avoided; due to the fact that long-distance material conveyance is completed through the conical material conveying pipe without the conveying blade in the conical material conveying pipe, the manufacturing cost is low, and maintenance is not needed.
