As Fig. 1,2,3,4, shown in 5, the utility model is by main frame [1], base soil is pulverized stirring conveyor structure [II], form with Unfired brick conveyer structure [III] three parts, wherein main frame [1] is by support 1, form brick cassette holder 2, the end, touch 3, guiding principal post 4, motor 5, V belt 6, pulley concial disk 7, drive pinion 8, gap bridge gear wheel 9, gap bridge pinion 10, main shaft gear wheel 11, power transmission shaft 12, gap bridge axle 13, main shaft 14, eccentric wheel 15, slide block pedestal 16, slide block 17, push rod 18, top board 19, crank 20, connecting rod 21, sliding beam 22, punching patrix 23, bucket 24, both arms fork 25, quantitative feed box 26, top screw 27, bolt 28 is formed, it is characterized in that: motor 5 is by V belt 6, pulley concial disk 7 is connected with power transmission shaft 12, power transmission shaft 12 is by pinion 8, gap bridge gear wheel 9, be connected with the axle 13 of passing a bridge, the axle of passing a bridge is by gap bridge pinion 10, main shaft gear wheel 11 is connected with main shaft 14; Two eccentric wheels 15, be installed in the both sides of main shaft gear wheel 11, the two pairs of slider frames 16 are installed in the two ends of two eccentric wheels 15 respectively and are clipped on the main shaft 14, two slide blocks 17 place the centre of two pairs of slider frames 16 respectively, the every pair of slider frame 16 respectively by bolt 28 fastening after, slide in the middle of respectively two slide blocks 17 being controlled at, the spiral shell inspection of push rod 18 bottoms is tightened in the screw of slide block 17: push rod 18 upper ends are equipped with top board 19, and top board 19 is fastened on the upper end of push rod 18 by top screw 27; The two ends of main shaft 14 link to each other with crank 20, and sliding beam 22 is installed on the guiding principal post 4, and connecting rod 21 links together crank 20 and sliding beam 22, and punching patrix 23 is installed on the sliding beam 22; Counterdie 3 is arranged on the forming brick cassette holder 2, and on position that punching patrix 23 matches, forming brick cassette holder 2 places support 1 upper end; Bucket 24, quantitative feed box 26 join by both arms rocking bar 25 and sliding beam 22.

Operation principle of the present utility model is: motor 5 is by V belt 6, belt pulley 7 drives power transmission shaft 12, the drive pinion 8 that is contained on the power transmission shaft 12 also rotates thereupon, drive pinion 8 drive again with its engagement gap bridge gear wheel 9, gear wheel 9 drives the axle 13 of passing a bridge again and rotates, the axle 13 of passing a bridge drives gap bridge pinion 10 and rotates, gap bridge pinion 10 drives main shaft gear wheel 11 rotations with its engagement, through drive pinion 8, gap bridge gear wheel 9, gap bridge pinion 10, the deceleration rear drive main shaft 14 of main shaft gear wheel 11 rotates, main shaft 14 drives two cranks 20 that are contained in its two ends and rotates, crank 20 promotes connecting rod 21 motions, promotes connected sliding beam 22 again and moves up and down along two guide upright posts 4; At this moment, two punching patrixes 23 that are installed on the sliding beam 22 promptly move with it, and punching patrix 23 matches with bed die 3 and the base soil pressure in the bed die 3 can be made adobe.

The top board 19 of two bed die 3 bottoms moves up and down under the promotion of eccentric wheel 15, slide block 17, push rod 18, and adobe is ejected table top.

When sliding beam 22 moves up and down, also move forward and backward by arm fork 25 coupled movable bucket 24, quantitative feed boxes 26 thereupon, sun-dried mud brick is sent into bed die 3, and the adobe that will eject table top is pushed on the Unfired brick conveyer structure III.

The process of brickmaking is: when sliding beam 22 is in lower dead point position, punching patrix 23 is stamped down to the position, the base soil pressure that bed die 3 fills up is made adobe, move on to the position behind the quantitative feed box 26 at this moment, when quantitative feed box 26 moved to the dead-centre position, punching patrix 23 was along with sliding beam 22 rises to predefined height, top board 19 ejects table top with adobe, simultaneously, 26 reaches of quantitative feed box put in place, and adobe is pushed on the Unfired brick conveyer structure III; Top board 19 is along with eccentric wheel 15 rotates to the bottom that falls to bed die 3 behind the certain angle rapidly, and the base soil in the quantitative feed box 26 falls in the bed die 3; When sliding beam 22 moves downward by top dead-centre, just begun next working cycles.

When maintain and replace push rod 18, the top screw 27 that at first will be fastened on push rod 18, the top board 19 is turned on, and successively takes out with top board 19, take out after the top board 19, and the bolt 28 on two slide block beams 16 all unclamped, then push rod 18 is backed out from slide block 17, and in bed die 3, proposed.

The utility model has the advantages that: when maintain and replace hollow brick pressing machine push rod 18, no Need employ any hanging device, change the required time of push rod 18 from came contracting one to two day Being short to 10-20 minute gets final product. Thereby greatly reduce labour intensity and maintenance cost, and also For the user has won the valuable production time.
