Abstract

The utility model relates to a small-size single screw brick extruder, which is composed of a machine base, an extruding mechanism, a mud pressing mechanism, a speed reduction controlling box, etc. The speed reduction controlling box of the small-size single screw brick extruder is composed of a left noumenon and a right noumenon which is divided into an upper box body and a lower box body. The left noumenon comprises a power input shaft gear and a retarding stage gear. The right noumenon comprises a power output shaft gear which is arranged on the shaft of a main machine. The utility model adopts a pressing type bearing seat which can directly press the bearing of the retarding stage gear shaft on the outer wall of the left noumenon and is composed of a seating, a bearing cover and screws. The utility model has the advantages of simple structure, easy processing and manufacture, low cost, etc. (The cost of the speed reduction controlling box is only 60% as much as the existing similar products.) The brick making machine is suitable for using in small-size brickyards in the countryside.

Description

Small-sized single-screw extruder

The utility model relates to brickmaking mechanical, especially a kind of small-sized single-screw extruder.

Existing small-sized single-screw extruder is generally by support, extrusion mechanism, mud-pressing mechanism and for extrusion mechanism with press mud machinery to provide the decelerating manoeuvre case of power to form.The decelerating manoeuvre box body of this class extruder generally is made of case lid and casing, in order to guarantee the correctness of transmission axis mutual alignment, adds the man-hour difficulty and has relatively high expectations, and casing cost proportion in the complete machine cost is bigger, and it is also not too convenient to keep in repair.

The purpose of the utility model, be higher at existing small-sized single-screw extruder decelerating manoeuvre case cost of manufacture, maintenance is shortcoming not too easily, provides a kind of decelerating manoeuvre case to make easily, cost is lower, easy to maintenance, is suitable for the small-sized single-screw extruder that the small-sized brick field in present rural area uses.

The utility model purpose can realize like this: a kind of small-sized single-screw extruder, it comprises support, be positioned at the extrusion mechanism on the support, by feed hopper, the feeding mechanism that mud cylinder and transmission case are formed, and the decelerating manoeuvre case that power is provided for described extrusion mechanism and transmission case by boss rod, described support tail end has supplying apparatus to pass the bearing block of the boss rod end of described decelerating manoeuvre case, the decelerating manoeuvre case that it is characterized in that described small-sized single-screw extruder is made of the left body and the right body of mutual perforation, comprise power input shaft gear and retarding stage gear in the described left body, retarding stage gear shaft two ends comprise one respectively by the bearing of device at this retarding stage gear shaft terminal, the bearing embedding is pressed on the cover for seat of described left body outer wall, be arranged in the bearing cap of sitting cover, and dress is sat the pressing type bearing block that screw constituted of covering device on left body; Described right body is made of upper box and the lower box that can cut open along plane, described boss rod place, device is arranged on described boss rod and the power output shaft gear that is meshed with described retarding stage gear in it.

The characteristics of described scheme: the one, the left body and the right body that change the decelerating manoeuvre case into left and right sides structure by the case lid and the casing of up-down structure, because the power output shaft geared system in the right body is on boss rod, right not load-bearing of body self, so it can select for use thin metallic plate to make, thereby reduces cost; The 2nd, the retarding stage gear has adopted the compression type bearing block, this compression type bearing block can suitably be regulated its position as required, must be on left body Working position dead eye accurately, not only greatly reduce the difficulty of processing of left body, and device get up also very convenient; The 3rd, right body is divided into upper box and lower box, and it is very convenient not only to assemble the power output shaft gear, and breaks down at the decelerating manoeuvre case, and when needing repairing, only need upper box is taken off, just boss rod and power output shaft gear can be taken out, very simple and convenient.

Facts have proved: the small-sized single-screw extruder that adopts the utility model to make, not only make, keep in repair all very convenient, and the cost of manufacture of its decelerating manoeuvre case only is 60% of existing similar dry product, and the small-sized brick field that is specially adapted to present rural area uses, and has reached the purpose of this utility model.

The utility model has following accompanying drawing, and accompanying drawing has been put down in writing an instantiation.

Fig. 1 is the utility model structural representation, for simplicity's sake, and the control stick part of not drawing.

Fig. 2 be the A-A of Fig. 1 to view, for clearlying show its structure, cutd open the belt pulley 71 that links to each other with power input shaft, the bearing block 41 and the part support of device boss rod.

Fig. 3 is the enlarged drawing of broken section part among Fig. 1, and it shows the concrete structure figure of compression type bearing block 8 among Fig. 2.

Example be described as follows (referring to Fig. 1-Fig. 3):

Extrusion mechanism 4 is arranged on the support 1, by mud cylinder 3, feed hopper 2 and transmission case 5 constitute feeding mechanism, decelerating manoeuvre case in the example is by left body 10, constitute the upper box 9 and the lower box 91 of right body, be positioned at the power input shaft gear (not shown) and the gear shaft 7 thereof of left body 10, be positioned at the retarding stage gear (not shown) and the gear shaft 11 thereof of left body 10, be positioned at the retarding stage gear (not shown) and the gear shaft 11 thereof of left body 10, the compression type bearing block 8 of device retarding stage gear, the power output shaft gear (not shown) that is installed on the boss rod 42 and is arranged in right body constitutes, boss rod 42 passes the decelerating manoeuvre case, and its end is the bearing block 41 that is positioned at support 1 tail end.71 is belt pulley, and 6 is suspension ring.

The compression type bearing block 8 that lays respectively at retarding stage gear shaft two ends in the example comprises the bearing 14 that is installed on reduction gearing axle 11 axle heads, with bearing 14 embeddings be pressed on left body 10 outer walls cover for seat 12, bearing block 13, and the through hole of screw 15,16 that cover for seat 12 is installed on left body 10 outer walls for passing for the reduction gearing axle on the left body 10.

Right body in the example can directly be welded with metal sheet, and the 92nd, strengthen the muscle of its stiffness.The 72nd, the power input shaft bearing block.

Other structure of this example and the course of work and existing small-sized single-screw extruder are similar, here no longer narration.
