NOVELTY - The device comprises a crushing mechanism whose a discharging port is connected with a feed port of a carbon-making mechanism. The crushing mechanism includes a base arranged on a crushing chamber. An outlet of the crushing chamber is provided with a fan. An end of the base is connected with a motor. An electric machine is connected with the fan. A discharging tube is arranged on an upper part of the fan. An upper part of the discharge tube is provided with a discharging tube head. The carbon-making mechanism comprises a fixing machine frame.    USE - The device is useful for making carbon from waste straw pole (claimed).    ADVANTAGE - The device is simple in structure, eco-friendly, reasonable in design, inexpensive, convenient to maintain and simple to operate, has reduced labor intensity, reduces the storage and transportation process of middle material, and avoids way for forbidding burning straw.    DETAILED DESCRIPTION - The device comprises a crushing mechanism whose a discharging port is connected with a feed port of a carbon-making mechanism. The crushing mechanism includes a base arranged on a crushing chamber. An outlet of the crushing chamber is provided with a fan. An end of the base is connected with a motor. An electric machine is connected with the fan. A discharging tube is arranged on an upper part of the fan. An upper part of the discharge tube is provided with a discharging tube head. The carbon-making mechanism comprises a fixing machine frame whose upper end part is provided with a controller. A lower part of the controller is connected with a water tank. An upper part of the machine frame is connected with a heater that is provided with an upper extruding mold. An upper part of the mold is connected with a hopper. A water tank is connected with the extruding mold through a water pump and a water tube. The extrusion mold is provided with a humidifier. The water pump of the heater is connected with a controller through a control line. An inner extruding mold is provided with a temperature and humidity sensor that is connected to the controller. The temperature and humidity sensor is utilized for detecting temperature and humidity of stream in the inner extruding mold. The controller stops working of the water pump and the heater when the temperature and humidity reaches to standard. The controller allows start working of the water pump and the heater, when the temperature and humidity does not reach to standard.
