Device for preventing materials from adhering to interior of main machine

A device for preventing materials from adhering to the interior of a main machine comprises a collecting hopper, a feeding port communicated with an external feeding component is formed in the top of the collecting hopper, a guide-out port communicated with a stirring main machine is formed in the bottom of the collecting hopper, and a washing header pipe is arranged on the side portion of the collecting hopper. An auxiliary pipe communicated with the washing main pipe is arranged on the periphery of the collecting hopper, and a plurality of washing sub-pipes facing the stirring main machine are arranged at the bottom of the auxiliary pipe. According to the invention, the manner of arranging the collecting hopper is adopted, even if certain adhesion exists in the collecting hopper, the adhesion can be naturally scoured into the stirring main machine, and then the manner of arranging the scouring sub-pipe is utilized, so that the adhesion of materials in the stirring main machine is avoided. 一种防止主机内部粘料的装置，包括一汇
