The end of the transverse plate far away from the discharge hole has larger surface area for blocking materials, and meanwhile, the blocking effect of the end of the transverse plate facing the discharge hole on the materials is reduced, so that argil is convenient to collect into a brick body.
Further, the transverse plate is chamfered towards one end of the discharge hole. The transverse plate is chamfered, so that the distance between one end of the transverse plate facing the discharge hole and the inner wall of the material extrusion cavity is increased, the argil at the corner of the argil body is convenient to gather, and the phenomenon of layering caused by the transverse plate to the corner of the argil body is avoided.

Through setting up the aircraft nose into first aircraft nose portion and second aircraft nose portion, set up the carriage simultaneously on the diaphragm, make the diaphragm pass through the carriage and can dismantle with the aircraft nose and be connected to the convenience is installed and is changed the diaphragm.
Furthermore, the inner cross section of the first machine head part gradually transits from a circle to a rectangle along the material flowing direction, two wedge-shaped flow guide blocks are symmetrically arranged in the first machine head part along the central line, and the flow guide blocks are fixedly connected with the first machine head part. The inner cross section of the first machine head part is set to be circular, so that smooth transition connection with a charging barrel in the prior art is facilitated, and the blocking effect of the inner wall of the first machine head part on materials is reduced; through setting up the water conservancy diversion piece, conveniently will follow the material that the circular cross-section of first aircraft nose flowed in along the flow direction of material toward the both ends water conservancy diversion of rectangular cross-section's width. Meanwhile, the arrangement of the flow guide block ensures that the argil in the first machine head part cannot rotate around the central line of the material extrusion cavity, so that the phenomenon that the transverse plate is damaged due to the contact with the rotating argil is avoided, and the service life of the transverse plate is prolonged.
Further, the height of the middle channel is equal to the height of the rectangular section of the first handpiece. When the materials move in the first machine head part, the extrusion force of the materials in the middle channel in the vertical direction is smaller.

The head 5 is divided into a first head part 51 and a second head part 52 along the axial direction, and the first head part 51 is connected with the second head part 5 through a bolt. The inner cross section of the first machine head part 51 is gradually transited from a circle to a rectangle along the material flowing direction, two wedge-shaped flow guide blocks 8 are symmetrically arranged inside the first machine head part 51 along the central line, the flow guide blocks 8 and the first machine head part 51 are welded and fixed, and a middle channel is arranged between the two flow guide blocks 8.
