Vacuum extruder horizontally-juxtaposed double reamer

The utility model provides horizontally-juxtaposed double reamers of a vacuum extruder. The lower-level mud cylinders of the extruder are double reamers which are horizontally juxtaposed. The center distance between the two reamers is smaller than the diameter of each mud cylinder. Each mud cylinder comprises two symmetric halves which are connected through bolts. Wear resistant linings are equipped inside the mud cylinders. A front flange and a rear flange are provided with bolt holes. The mud cylinders are connected with a blanking case and a head of the extruder. The horizontally-juxtaposed double mud cylinders provided in the utility model are simultaneously propelled by the two reamers and enable a mud conveying capacity twice the mud conveying capacity by a single reamer. The ports of the mud cylinders are oblate. The machine port forming difficulties are then significantly alleviated. The application of the double reamers makes the large-output extruder manufacture in our country reach a new level. The
