This practicality can be disposable will be built the fragment of brick tight simultaneously, under the drive of promotion hydro-cylinder for the brick successive layer separates, and the operation is broken off with the fingers and thumb to the polylith brick body once only, and the process is simple and practical, convenient operation.
The concrete separating equipment in the two schemes performs separating treatment on vertically stacked blanks, the blanks are bonded tightly, the blanks are easy to damage during separating, and particularly, the plates are broken after being separated frequently, so that the qualification rate of products is seriously influenced. In addition, steam curing devices in existing equipment steam cure the oppositely stacked green bodies, so that after the green bodies are cut by the existing cutting devices, the cut green bodies are stacked vertically for convenience of stacking, and even if the green bodies are separated before steam curing, the green bodies are adhered tightly due to self gravity.

In this embodiment, the plurality of lower susceptors 523 are mounted together on a long connecting frame, and the lead screw of the lead screw elevating mechanism 534 is connected to the lower end surface of the connecting frame through a bearing. The downward breaking-off telescopic mechanism 521 is a cylinder, the cylinder body of the cylinder is fixedly connected with a lower base 523, the end part of a piston rod of the cylinder is fixedly connected with a lower clamping piece 522, and three pairs of downward breaking-off telescopic mechanisms 521 and the lower clamping piece 522 are arranged on a single base 523.

In this embodiment, the pressure when the downward separating and stretching mechanism 521 extends needs to be greater than the pressure when the upward separating and stretching mechanism 511 extends, so that when the lifting device 53 jacks, the upward separating and stretching mechanism 511 contracts, and the green body is jacked up and is higher than the rest of the green bodies by a certain height, thereby completing the separating.
As shown in fig. 9, the plurality of lifting guide mechanisms 54 are arranged at equal intervals along the feeding direction, and each lifting guide mechanism includes a connecting block 541, a vertical guide rail 542, and a vertical sliding seat 543. Wherein, vertical guide rail 542 sets up on connecting block 541 and extends along the direction of height, and connecting block 541 breaks the link fixed connection of device 52 with breaking off with the fingers and thumb down, and vertical slide 543 fixed mounting is in frame 2 and cooperatees with vertical guide rail 542. The lifting guide mechanism 54 can ensure the direction accuracy of the downward separating device 52 during lifting, improve the clamping precision of the green body and prevent the green body from being damaged in the clamping process.
When clamping the blank, the cylinders of the upper breaking-off device 51 and the lower breaking-off device 52 which are positioned in the same height direction extend out to tightly push the upper end of one layer of blank, and the rest cylinders keep a contraction state. Then, the lifting device 53 works to drive the lower breaking-off device 52 to ascend, so that the upper clamping piece 512 and the lower clamping piece 522 clamp the green bodies, and then the transverse driving device 3 works to move the frame 2 and drive the clamped green bodies to move, thereby completing the breaking-off of a layer of green bodies. In actual work, when the blank thickness is small, the blank can be clamped only by selecting the single-row telescopic mechanism, when the blank thickness is large, the width of the clamping piece on the single-row telescopic mechanism is smaller than the blank thickness, so that the blank cannot be clamped, and at the moment, the blank can be clamped by adopting the joint work of the multiple-row telescopic mechanism. Therefore, according to the embodiment, the blank clamping operation can be selectively performed by adopting the single-row telescopic mechanisms or the multi-row telescopic mechanisms with different sizes according to the blanks with different thicknesses, the application range of the wet breaking machine to the thickness of the blanks is increased, and the practicability of the wet breaking machine is improved.
However, the above-mentioned way of clamping the blank up and down also has a certain problem, that is, the bottom of the existing horizontal steam-curing bottom plate is required to bear the blank, so the lower clamp 522 can not tightly push the blank from the lower part of the blank. In response to this problem, the present embodiment takes the following measures.
As shown in fig. 10, the horizontal steam-curing bottom plate 6 includes a pair of side plates 61 arranged in parallel, the side plates 61 are connected by a plurality of long blocks 62, the long blocks 62 are arranged at equal intervals along the length direction of the side plates 61, and a gap through which the lower clamping member 522 can pass is formed between the adjacent long blocks 62. The upper ends of the telescopic members of the row of downward snapping telescopic mechanisms 521 are connected with a long seat 524, the long seat 524 extends along the feeding direction, and a plurality of lower clamping members 522 are arranged on the long seat 524 at equal intervals along the length direction and correspond to the gaps of the horizontally arranged steam-curing bottom plate 6 one by one. By the mode, the problem that the blank body on the traditional transverse steam curing bottom plate is difficult to clamp up and down is solved skillfully, the design is simple and skillful, and the installation and the operation are convenient.
Meanwhile, for the structure of the horizontal steam-curing bottom plate 6, the blank receiving device 105 capable of lifting is also arranged on the overturning platform 103. As shown in fig. 19, the blank receiving device 105 includes a lifting mechanism, such as an air cylinder, an oil cylinder, an electric push rod, etc., disposed on the turning table 103 for fixing the inner side surface of the horizontally placed steam-curing bottom plate 6, the lifting mechanism is provided with a receiving table, the receiving table is provided with a plurality of rows of support bars arranged at equal intervals, and each row of support bars is provided with a strip-shaped support bar. The width of the support strip is smaller than the gap between the long strip blocks 62, therefore, when the horizontally placed steam curing bottom plate 6 is fixed on the overturning platform 103, the lifting mechanism works, the support strip can penetrate through the gap between the long strip blocks 62 and is attached to the surface of the blank on the other inner side face of the overturning platform 103, after the overturning platform 103 overturns, the lifting mechanism controls the support strip to descend, and the blank is placed on the horizontally placed steam curing bottom plate 6. By the aid of the method, when the blank is transferred to the transverse steam-curing bottom plate 6 from the vertical steam-curing bottom plate 8, the lifting height of the lifting mechanism can be freely adjusted according to the size of the blank, so that the support bars are attached to the blank, and the blank cannot be attached to the transverse steam-curing bottom plate 6 during transfer to prevent the blank from being failed in transfer and damaged.
It is worth mentioning that, in order to prevent that the horizontal steam-curing bottom plate 6 from moving on the bottom plate conveying device 4 when clamping the blank body, thereby resulting in that the blank clamping precision is influenced, the blank body is impaired, even the problem of blank clamping failure appears, the embodiment has set up bottom plate positioner 7. As shown in fig. 11, the bottom plate positioning device 7 includes a positioning frame 71 and a positioning cylinder 72, wherein the positioning frame 71 is fixedly mounted on the base 1, and a through hole is formed in the positioning frame to penetrate through the base. The cylinder body of the positioning cylinder 72 is fixedly mounted on the positioning frame 71, the piston rod of the positioning cylinder extends upwards and penetrates through the through hole, meanwhile, the side plate 61 is provided with a positioning hole 63 for the piston rod to penetrate through, and a plurality of positioning holes 63 are formed in the single side plate 61 along the length direction of the single side plate in the embodiment. After the transverse steam-curing bottom plate 6 reaches a preset position, a piston rod of the positioning cylinder 72 extends upwards to penetrate through the positioning hole 63 in the side plate 61, so that the transverse steam-curing bottom plate 63 stays at the preset position, and the phenomenon that the blank body is damaged and fails to be broken due to movement of the transverse steam-curing bottom plate in the blank clamping process is prevented. In order to further enhance the positioning effect on the horizontal steam-curing bottom plate 6, in the embodiment, the front side and the rear side of the base 1 are respectively provided with one positioning device 7, so that the positioning on the horizontal steam-curing bottom plate 6 is more stable.
In summary, the wet breaking machine is different from a traditional wet breaking machine, and can break the transversely stacked green bodies according to the transverse driving device 3, the upper breaking device 51, the lower breaking device 52 and the lifting device 53, so that the situation that the green bodies are damaged easily or even failed in breaking due to large bonding force caused by self gravity when the vertically stacked green bodies are broken by the traditional breaking machine is avoided. The wet breaking machine has the advantages of ingenious structure, high breaking efficiency and high breaking accuracy, does not easily damage the blank body, and improves the yield of concrete blocks or plates.
