Hydraulic brick extruding machine

Abstract

The invention discloses a hydraulic brick extruding machine. The hydraulic brick extruding machine comprises an extruding head, a loading cylinder and a hydraulic pushing and pressing mechanism whichare sequentially fixed from front to back. The two ends of the extruding head are each of a conical cylindrical structure with the opened end. The loading cylinder is integrally and transversely arranged, and the two ends of the loading cylinder are each of a straight cylinder structure with the opened end. One of the two ends of the loading cylinder is a discharging end which is in abut joint with and communicates with a feeding opening of the extruding head. The other end of the loading cylinder is a pushing and pressing start end of a piston in the hydraulic pushing and pressing mechanism.The circumferential side wall of the piston is in sliding fit connection with the inner side wall of the loading cylinder. The hydraulic brick extruding machine is characterized in that a reserved space allowing the loading cylinder to wholly fall in is formed between the feeding opening of the extruding head and the front end surface of the piston of the reset hydraulic pushing and pressing mechanism, and the loading cylinder and the extruding head are in detachable and fixed connection and positioned in the reserved space. The hydraulic brick extruding machine has the advantages that mud materials in the loading cylinder can be fully pushed out, and the degree of compaction of brick bars extruded from the extruding head can be higher, thus the strength of the finally-obtained bricks is helped to be improved.

Description

technical field [0001] The invention belongs to the field of brick making equipment, and in particular relates to a hydraulic brick extrusion machine. Background technique [0002] The hydraulic brick extrusion machine is a kind of equipment for extruding and producing brick strips. After the brick strips are cut by the cutting equipment, the bricks can be obtained. After the bricks are sintered, the finished bricks can be obtained. [0003] At present, the structure of the existing hydraulic brick extrusion machine (also known as: brick making machine or brick extrusion machine) is CN102581935B (see figure 1 ) or the announcement number is CN201217247Y (see figure 2 ) The hydraulic brick extrusion machine structure shown in the technical scheme. But existing hydraulic brick extruder all has the same weak point, below with the technical scheme that notification number is CN102581935B is example to illustrate this weak point. [0004] The patent with the notification numb...

AI Technical Summary

Problems solved by technology

In this way, when the piston pushes the mud, part of the mud will be squeezed out from the feed hole, resulting in the degree of compaction of the brick strips extruded by the machine head 1 (the degree of compaction is also "density") ) is not high enough, which ultimately affects the strength of the bricks

[0009]3. The resistance of piston retraction will increase

The reason is: the mud in the sealed material storage chamber 4 will fall into the space behind the piston during the pushing process to block the retreat of the piston, which is not conducive to maintaining the reliable use of the structure of the lower piston assembly 12 for a long time.
