Description

Technical Field

[0001] The present invention belongs to the technical field of concrete material production equipment, and more specifically, relates to a wet splitting system for concrete blocks or slabs. Background Art

[0002] In the field of autoclaved aerated concrete material production, autoclaved aerated concrete blocks are porous concrete products made from siliceous materials (such as yellow sand) and calcareous materials (lime and cement) through processes such as batching and metering, mixing and pouring, static curing and cutting, and autoclave curing. Autoclaved aerated concrete slabs are porous concrete products with a pre-placed steel mesh cage of a certain specification inside autoclaved aerated concrete blocks. However, during the production process of autoclaved aerated concrete blocks or slabs, the siliceous materials and calcareous materials will undergo a hydration reaction during high-temperature autoclave curing, causing the finished blocks or slabs to stick together. Therefore, it is necessary to split the finished blocks and slabs.

[0003] Currently, in the autoclaved aerated concrete block or slab production industry, the production process is roughly as follows: slurry pouring - static curing - cutting - standing the green body vertically - autoclave curing - splitting - finished product packaging. During this process, since the green body is vertically placed in the thickness direction, that is, multiple slabs or blocks are stacked together for autoclave curing, this results in the adhesion between layers of the finished autoclaved slabs or blocks after autoclave curing. Therefore, it is necessary to add a splitting device in the subsequent process to separate the adhesion. Due to the tight adhesion, the blocks or slabs are often damaged during splitting, especially the slabs often show fracture phenomena after splitting, seriously affecting the product qualification rate.

[0004] For example, a patent document with the Chinese patent application number: CN201420809208.3 and the publication date: June 17, 2015, discloses a block separator and its splitting traction device. In the splitting traction device, the bearing frame is connected to the fixed clamping device through the bearing arm, the moving clamping device is connected through the lifting arm of the lifting frame, and the lifting of the lifting frame on the bearing frame is realized by the pushing of the separation driving device between the bearing beam and the lifting beam, and the moving clamping device is driven to move up and down relative to the fixed clamping device.

[0005] Another example is the Chinese patent application number: CN201920696234.2, the publication date: February 28, 2020, which discloses a sand aerated concrete block production mechanism, including two third beams, the two third beams are arranged in parallel, and vertical downward support rods are installed on the bottom surface of the third beams, and a number of first beams are arranged between the support rods, and the first beams are arranged in layers from top to bottom, and the two ends of the first beams are connected to the guide seat, and the support rods are all passed through the guide seat, and the guide seat and the support rod are connected by a linear bearing; the support rods are fixedly installed on the mounting base; the outer side of the guide seat is installed with a connecting plate extending outward and arranged horizontally, and two first through-holes are also provided in the middle of the guide seat. This utility can clamp the stacked bricks at the same time at one time, and under the drive of the lifting cylinder, the bricks are separated layer by layer, and multiple bricks can be split at one time. The process is simple and practical, and the operation is convenient.

[0006] The concrete splitting equipment in the above two schemes splits the blanks stacked vertically, and there is a problem of tight adhesion between the blanks. The blanks are easily damaged during splitting, especially the plates often break after splitting, which seriously affects the qualified rate of the product. In addition, the steaming device in the existing equipment steams the blanks stacked vertically. Therefore, after the existing cutting device cuts the blanks, on the one hand, for the convenience of stacking, on the other hand, for the convenience of steaming, the cut blanks are stacked vertically. Even if the blanks are split before steaming, there will be a problem of tight adhesion between the layers due to their own gravity. However, there is no system in the prior art that is specifically designed to split horizontally stacked blanks, let alone a system that first turns the blanks into a horizontally stacked state and then splits them. Summary of the invention

[0007] 1. Problems to be solved

[0008] In view of the problem that the existing wet breaking systems for concrete blocks or panels all break apart blanks stacked vertically, and the bonding force between the blanks is relatively tight, which easily leads to breaking failure and reduces the yield rate, the present invention provides a wet breaking system for concrete blocks or panels, which can convert blanks stacked vertically into horizontal stacks, and break apart the horizontally stacked blanks, thereby reducing the probability of damage to the blanks during breaking and improving the yield rate of blocks or panels.

[0027] 3. Beneficial effects

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] (1) In the wet splitting system for concrete blocks or plates of the present invention, the cutting and conveying track and the vertically placed curing bottom plate can send the vertically stacked blanks to the side of the turnover machine. First, the semi-finished product crane lifts the horizontally placed curing bottom plate to the horizontal inner side of the turnover table for fixation, and then turns the turnover machine by 90° to make the horizontally placed curing bottom plate stand up, and the other inner side of the turnover table becomes horizontal. Then, the semi-finished product crane places the vertically placed blank together with the vertically placed curing bottom plate on the horizontal inner side of the turnover table and fixes it. Next, the turnover machine is reset to transfer the vertically placed blank to the horizontally placed curing bottom plate, and the blank becomes horizontally stacked. Then, the semi-finished product crane hoists the horizontally placed blank together with the horizontally placed curing bottom plate onto the horizontal curing track and sends it to the wet splitting machine for wet splitting work, avoiding the problem of damage to the blank during the splitting of the vertically stacked blank;

[0030] (2) In the wet splitting system for concrete blocks or plates of the present invention, the wet splitting machine can split the horizontally stacked blanks through the transverse driving device, the upper splitting device, the lower splitting device, and the lifting device, avoiding the situation that when the traditional splitting machine splits the vertically stacked blanks, the blank has a large bonding force due to its own gravity, is easily damaged or even the splitting fails. The wet splitting machine has a clever structure, high splitting efficiency and accuracy, is not easy to damage the blank, and improves the yield of concrete blocks or plates;

[0031] (3) In the wet splitting system for concrete blocks or plates of the present invention, by setting the lifting guiding mechanism, the direction accuracy of the lower splitting device during lifting can be ensured, the clamping accuracy of the blank can be improved, and the blank can be prevented from being damaged during the clamping process;

[0032] (4) In the wet splitting system for concrete blocks or plates of the present invention, both the transverse driving device and the lifting device are driven by a single motor, and a plurality of lead screw nut mechanisms or lead screw lifting mechanisms are driven to work synchronously through the synchronously rotating rotating shafts, thereby ensuring the working synchronism between the plurality of lead screw nut mechanisms or lead screw lifting mechanisms, enhancing the splitting accuracy of the blank, and avoiding damage to the blank;

[0033] (5) The wet splitting system for concrete blocks or slabs of the present invention has multiple rows of telescopic mechanisms and clamping members on both the upper and lower splitting devices, which can selectively use single-row telescopic mechanisms or multi-row telescopic mechanisms of different sizes for clamping the green body according to the thickness of the green body, increasing the adaptability range of the wet splitting machine to the thickness of the green body and improving the practicality of the wet splitting machine;

[0034] (6) In the wet splitting system for concrete blocks or slabs of the present invention, the upper end of the telescopic member of the lower splitting telescopic mechanism is connected to a long strip seat, and multiple lower clamping members are arranged on the long strip seat. The lower end of the horizontally placed curing floor is multiple long strip blocks arranged at intervals, and gaps for the lower clamping members to pass through are formed between the long strip blocks.

[0069] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0070] Embodiment

[0071] A wet splitting system for concrete blocks or plates is used to split the concrete green bodies before curing. The specific structure and working principle thereof will be described in detail below.

[0072] As Figure 18 shown, the system includes a cutting device 13, a cutting and conveying track 11, a semi-finished product crane 9, a tilter 10, a horizontal curing track 12, a wet splitting machine, a stacking crane 14, and a curing and conveying device 15.

[0073] Among them, the cutting device 13 is used to cut the concrete green bodies and stack the cut green bodies vertically. This is because it is more convenient to stack the cut green bodies vertically and the stacking is neater. If the green bodies are directly stacked horizontally, on the one hand, the operation is more troublesome and the green bodies are easily scattered and damaged, and on the other hand, the green bodies are also prone to uneven stacking, affecting the subsequent splitting and curing of the green bodies.

[0074] The cutting and conveying track 11 is located on one side of the tilter 10, one end of which is connected to the cutting device 13 and the other end extends to the tilter 10. There is a conveying trolley on the cutting and conveying track 11, and the vertical curing bottom plate 8 is located on the conveying trolley. As Figure 25 shown, the vertically stacked green bodies are sent from the cutting device 13 to the vertical curing bottom plate 8, and then the conveying trolley sends the vertically stacked green bodies to the tilter 10.

[0075] The horizontal curing track 12 is arranged on the other side of the tilter 10, the wet splitting machine is located on the horizontal curing track 12, and the horizontal curing track 12 is also provided with a conveying trolley, and a horizontal curing bottom plate 6 is arranged on the conveying trolley. The stacking crane 14 is located above the horizontal curing track 12, the curing and conveying device 15 is arranged on one side of the horizontal curing track 12, the semi-finished product crane 9 is arranged above the tilter 10, and at the same time, a vertical curing track 16 is arranged on one side of the tilter 10, and the vertical curing track 16 also has a conveying trolley.

[0076] As shown Figure 19 in FIG. 1, the tilting machine 10 mainly includes a tilting base 101, a tilting shaft 102, and a tilting table 103. Among them, the tilting shaft 102 is rotatably installed on the tilting base 101 and fixedly connected to the tilting table 103. The tilting base 101 is provided with a motor for controlling the rotation of the tilting shaft 102, and the output shaft of the motor is in transmission connection with the tilting shaft 102. When the motor works, it can drive the tilting shaft 102 to rotate, thereby driving the tilting table 103 to rotate. The tilting table 103 has an L-shaped structure, and fixing devices 104 for fixing the steam curing bottom plates are installed on the inner side surfaces of its two sides. Among them, the fixing device 104 is mainly used to fix the vertically placed steam curing bottom plate 8 and the horizontally placed steam curing bottom plate 6, and it can adopt common forms such as clamping jaws and clamping cylinders. The following specifically exemplifies one of the methods: The fixing device 104 adopts a structure in which a motor and a fixing plate are respectively arranged at both ends of one of the inner side surfaces of the tilting table 103. The output shaft of the motor is connected to a locking plate through a lead screw and nut mechanism. A slider is provided at the lower end of the locking plate, and a chute matching the slider is provided on this inner side surface. After placing the steam curing bottom plate between the fixing plate and the locking plate, only by driving the motor to work can the locking plate move towards the fixing plate, reducing the distance between the two, and realizing the locking of the steam curing bottom plate.

[0077] The above is the structure of the wet splitting system of this embodiment. For the specific operation of the wet splitting system on the green body, this embodiment provides a wet splitting process for concrete blocks or plates, including the following steps:

[0078] I. Tilting preparation

[0079] Before starting, as Figure 19 shown in FIG. 2, make the inner side surface of the tilting table 103 of the tilting machine 10 that fixes the horizontally placed steam curing bottom plate 6 in a horizontal state, and send the horizontally placed steam curing bottom plate 6 to the tilting table 103 for fixing through the semi-finished product crane 9. Then, as Figure 20 shown in FIG. 3, the tilting table 103 is tilted 90°, so that the inner side surface of the tilting table 103 that fixes the vertically placed steam curing bottom plate 8 is in a horizontal state. At this time, the horizontally placed steam curing bottom plate 6 is vertically fixed on the tilting table 103.

[0080] Send the vertically placed steam curing bottom plate 8 carrying the vertically stacked green bodies to the tilting machine 10 through the conveying trolley on the cutting and conveying track 11, and then as Figure 21 shown in FIG. 4, the semi-finished product crane 9 sends the vertically placed steam curing bottom plate 8 together with the vertically stacked green bodies thereon to the tilting table 103 for fixing.

[0081] II. Tilting the green body

[0082] As Figure 22As shown, when the tilter 10 operates and the tilting table 103 tilts 90°, the inner side of the horizontally placed curing base plate 6 for fixing becomes horizontal. At this time, the green body is transferred from the vertically placed curing base plate 8 to the horizontally placed curing base plate 6, and changes from a vertically stacked state to a horizontally stacked state.

[0083] III. Green body curing

[0084] The semi-finished product crane 9 sends the horizontally placed curing base plate 6 carrying the horizontally stacked green bodies as Figure 26 shown to the conveying trolley on the horizontally placed curing track 12. The conveying trolley sends the horizontally placed curing base plate 6 under the wet splitting machine. The wet splitting machine performs a splitting operation on the horizontally stacked green bodies. After the splitting is completed, the conveying trolley then sends the horizontally placed curing base plate 6 under the stacking crane 14. The stacking crane 14 hoists the green bodies onto the curing vehicle in the curing conveying device 15, making the green bodies return to a vertically stacked state, and then sending them into the curing device for autoclave curing.

[0085] IV. Tilter reset

[0086] As Figure 23 shown, after the green bodies together with the horizontally placed curing base plate 6 are transported away, the vertically placed curing base plate 8 still stays on the tilting table 103 and is in a vertical state. The tilting table 103 tilts 90°, becoming as Figure 24 shown with the vertically placed curing base plate 8 in a horizontal state. Then, the vertically placed curing base plate 8 is sent to the conveying trolley on the vertically placed curing track 16 to prepare for receiving the cut green bodies next time.

[0087] It is worth mentioning that, in order to improve the splitting efficiency, two horizontally placed curing tracks 12 are provided in this embodiment. When one horizontally placed curing track 12 conveys the green bodies to the wet splitting machine for splitting operation, the other horizontally placed curing track 12 sends a new horizontally placed curing base plate 6 to the tilter 10, and the semi-finished product crane 9 sends the new horizontally placed curing base plate 6 to be fixed on the reset tilting table 103 in step IV, and repeats the operations in steps I to IV.

[0088] The above is the specific wet splitting process of this system. However, the existing wet splitting machines are difficult to perform splitting work on the horizontally stacked green bodies. In view of this problem, this embodiment also provides a wet splitting machine specifically for the horizontally stacked green bodies.

[0089] This wet splitting machine mainly includes a base 1, a frame 2, a lateral driving device 3, a base plate conveying device 4, a splitting assembly 5, a horizontally placed curing base plate 6, and a base plate positioning device 7. The specific structure and working principle of this wet splitting machine will be described in detail below.

[0090] As Figure 1As shown, the base 1 and the frame 2 are the installation bases for the various devices of the wet splitting machine. Among them, there are a pair of frames 2, which are symmetrically installed on both sides of the base 1. It should be noted that the structures of the two frames 1 and the various components installed thereon are the same and are symmetrically arranged on the base 1. In this embodiment, only a single frame 2 and its installation components are described for convenience of description.

[0091] As Figure 2 shown, there are multiple bottom plate conveying devices 4, which are arranged on the base 1 along the feeding direction. Its specific structure is as Figure 5 shown, and it includes a pair of conveying seats 41, a conveying motor 42, a conveying shaft 43 and wheels 44. Among them, a pair of conveying seats 41 are symmetrically and fixedly installed on both sides of the base 1. The conveying motor 42 is fixedly installed on one of the conveying seats 41. The output shaft of the conveying motor 42 is drivingly connected to one end of the conveying shaft 43. The other end of the conveying shaft 43 is connected to the other conveying seat 41 through a bearing and is horizontally arranged. There are two wheels 44, which are fixedly sleeved at both ends of the conveying shaft 43. The bottom of the horizontally placed curing bottom plate 6 is provided with structures such as tracks that cooperate with the wheels 44, and it can be supported on the wheels 44. When the conveying motor 42 works, it can drive the conveying shaft 43 and the wheels on the conveying shaft 43 to rotate, and control the horizontally placed curing bottom plate 6 to move along the feeding direction. In order to facilitate the transfer of the horizontally placed curing bottom plate 6 from the horizontally placed curing track 12 to the bottom plate conveying device 4, the bottom plate conveying device 4 and the horizontally placed curing track 12 are at the same height and on the same straight line, so that the horizontally placed curing bottom plate 6 can be directly transferred from the horizontally placed curing track 12 to the bottom plate conveying device 4 and transferred back to the horizontally placed curing track 12 again after splitting.

[0092] As Figure 2 and Figure 3As shown in the figure, the lateral driving device 3 includes a lateral motor 31, a lateral speed reducer 32, a lateral rotating shaft 33, a lead screw nut mechanism 34, and a pushing seat 35. The lateral motor 31 is drivingly connected to the lateral speed reducer 32, and the lateral speed reducer 32 drives the lateral rotating shaft 33 to rotate. There are multiple lead screw nut mechanisms 34, which are arranged along the length direction of the frame 2 and fixedly connected to the frame 2. Specifically, two rows of equally spaced pushing seats 35 are symmetrically arranged on both sides of the base 1. The nut of the lead screw nut mechanism 34 is fixedly connected to the frame. The lead screw is horizontally arranged perpendicular to the feeding direction. One end of the lead screw is connected to the pushing seat 35 on one side of the base 1 through a bearing. A protective sleeve connected to the nut is sleeved on the outer side of the other end of the lead screw, which can prevent external dust, etc. from falling on the lead screw and affecting the normal operation of the lead screw. The lateral rotating shaft 33 passes through the nuts of multiple lead screw nut mechanisms 34 at the same time and is in screw transmission connection with each lead screw. Therefore, when the lateral motor 31 works, the rotation of the lateral rotating shaft 33 can drive each lead screw to rotate, so that each nut moves along the lead screw, driving the frame 2 fixedly connected to the nut to move perpendicular to the feeding direction. This method of using a synchronously rotating rotating shaft to drive multiple lead screw nut mechanisms 34 to work synchronously can ensure the working synchronism between multiple lead screw nut mechanisms 34, enhance the splitting accuracy of the blank, and avoid damage to the blank.

[0093] As Figure 3 shown, the splitting assembly 5 includes an upper splitting device 51, a lower splitting device 52, a lifting device 53, and a lifting guiding mechanism 54.

[0094] As Figure 6 shown, the upper splitting device 51 includes an upper splitting telescopic mechanism 511, an upper clamping member 512, and an upper base 513. The upper base 513 is fixedly installed on the inner side of the upper end of the frame 2. There are multiple pairs of upper splitting telescopic mechanisms 511 and upper clamping members 512. Among them, the upper splitting telescopic mechanisms 511 are equally spaced on the upper base 513 perpendicular to the feeding direction, and their telescopic members extend downward along the height direction and are fixedly connected to an upper clamping member 512. In this embodiment, the upper splitting telescopic mechanism 511 uses a cylinder. The cylinder block is fixedly connected to the upper base 513, and the end of its piston rod is fixedly connected to the upper clamping member 512. Three pairs of upper splitting telescopic mechanisms 511 and upper clamping members 512 are provided on a single base 513. There are multiple upper splitting devices 51, which are equally spaced at the upper end of the frame 1 along the feeding direction. Therefore, in this embodiment, three rows of upper clamping members 512 arranged perpendicular to the feeding direction are finally formed at the upper end of the frame 1.

[0095] As Figure 8As shown in the figure, the lifting device 53 is installed on the lower end face of the frame 2 and includes a lifting motor 531, a lifting speed reducer 532, a lifting rotating shaft 533, and a screw rod lifting mechanism 534. The lifting motor 531 is drivingly connected to the lifting speed reducer 532, and the lifting speed reducer 532 drives the lifting rotating shaft 533 to rotate. There are multiple screw rod lifting mechanisms 534, which are arranged along the length direction of the frame 2 and fixedly connected to the frame 2. The lifting rotating shaft 533 passes through multiple screw rod lifting mechanisms 534 and is simultaneously in screw transmission connection with the screws therein. The screws of the screw rod lifting mechanism 534 extend in the height direction, and their upper ends are connected to the lower splitting device 52 through bearings, while protective sleeves connected to the bases of the screw rod lifting mechanisms 534 are sleeved on the outer sides of their lower ends. This method of using a synchronously rotating rotating shaft to drive multiple screw rod lifting mechanisms 534 to work synchronously can ensure the working synchronism between the multiple screw rod lifting mechanisms 534, enhance the splitting accuracy of the green body, and avoid damage to the green body.

[0096] As Figure 7 shown in the figure, there are multiple lower splitting devices 52, and the number thereof corresponds to the number of screw rod lifting mechanisms 534. It includes a lower splitting telescopic mechanism 521, a lower clamping member 522, and a lower base 523. There are multiple pairs of the lower splitting telescopic mechanism 521 and the lower clamping member 522. Among them, the lower splitting telescopic mechanisms 521 are arranged at equal intervals on the lower base 523 perpendicular to the feeding direction, and their telescopic members extend upward in the height direction and are fixedly connected to a lower clamping member 522. In this embodiment, multiple lower bases 523 are jointly installed on a long strip-shaped connecting frame, and the screws of the screw rod lifting mechanism 534 are connected to the lower end face of the connecting frame through bearings. The lower splitting telescopic mechanism 521 uses a cylinder, the cylinder body of which is fixedly connected to the lower base 523, and the end of its piston rod is fixedly connected to the lower clamping member 522. Each single base 523 is provided with three pairs of the lower splitting telescopic mechanism 521 and the lower clamping member 522. The lower splitting devices 52 are arranged at equal intervals at the lower end of the frame 1 along the feeding direction. Therefore, in this embodiment, three rows of lower clamping members 522 perpendicular to the feeding direction are finally formed at the lower end of the frame 1, and the positions of each row of lower clamping members 522 correspond to those of the multiple rows of upper clamping members 512 of the upper splitting device 51, that is, they are in the same height direction. In this embodiment, the pressure when the lower splitting telescopic mechanism 521 extends needs to be greater than the pressure when the upper splitting telescopic mechanism 511 extends. Thus, when the lifting device 53 performs jacking, the upper splitting telescopic mechanism 511 can be contracted, and the green body is jacked up to a certain height higher than the other green bodies to complete splitting.

[0097] As Figure 9As shown, the lifting guide mechanism 54 has multiple parts, which are arranged at equal intervals along the feeding direction, and include a connecting block 541, a vertical guide rail 542 and a vertical slide 543. Among them, the vertical guide rail 542 is set on the connecting block 541 and extends in the height direction, the connecting block 541 is fixedly connected to the connecting frame of the lower breaking device 52, and the vertical slide 543 is fixedly installed on the frame 2 and cooperates with the vertical guide rail 542. The lifting guide mechanism 54 can ensure the directional accuracy of the lower breaking device 52 when lifting and lowering, improve the clamping accuracy of the blank, and prevent the blank from being damaged during the clamping process.

[0098] When clamping the blank, the cylinders of the upper breaking device 51 and the lower breaking device 52 located in the same height direction extend out to tighten the upper end of a layer of blank, and the other cylinders remain in a contracted state. Then the lifting device 53 works, driving the lower breaking device 52 to rise, so that the upper clamp 512 and the lower clamp 522 clamp the blank, and then the lateral drive device 3 works, moving the frame 2 and driving the clamped blank to move, completing the breaking of a layer of blank. In actual work, when the thickness of the blank is small, only a single-row telescopic mechanism can be selected to clamp the blank, and when the thickness of the blank is large, the width of the clamp on the single-row telescopic mechanism is less than the thickness of the blank, resulting in the inability to clamp the blank. At this time, multiple rows of telescopic mechanisms can be used to work together to clamp the blank. Therefore, this embodiment can selectively use single-row telescopic mechanisms or multiple rows of telescopic mechanisms of different sizes to clamp the blank according to blanks of different thicknesses, which increases the adaptability of the wet breaking machine to the thickness of the blank and improves the practicality of the wet breaking machine.

[0099] However, this method of clamping the blanks from top to bottom also has certain problems, that is, the bottom of the existing horizontal steaming bottom plate needs to support the blanks, so the lower clamp 522 cannot tighten the blanks from the bottom. To solve this problem, the following measures are taken in this embodiment.

[0100] like Figure 10 As shown, the horizontal steam curing bottom plate 6 includes a pair of parallel side plates 61, and the pair of side plates 61 are connected by a long strip 62. There are multiple long strips 62, which are arranged at equal intervals along the length direction of the side plates 61, and gaps are formed between adjacent long strips 62 for the lower clamps 522 to pass through. The upper end of the telescopic parts of a row of lower split telescopic mechanisms 521 is connected to a long seat 524, which extends along the feeding direction, and multiple lower clamps 522 are arranged at equal intervals along its length direction, corresponding to the gaps of the horizontal steam curing bottom plate 6. In this way, the problem of difficulty in clamping the blanks on the traditional horizontal steam curing bottom plate up and down is cleverly solved, and the design is simple and clever, and easy to install and operate.

[0101] Meanwhile, in view of the structure of the horizontally placed steaming bottom plate 6, this embodiment also provides a lifting and lowering blank receiving device 105 on the turning table 103. Figure 19As shown, the blank receiving device 105 includes a lifting mechanism, such as a cylinder, an oil cylinder, an electric push rod, etc., which is arranged on the inner side of the turning table 103 for fixing the horizontal steaming bottom plate 6. The lifting mechanism is provided with a receiving table, and the receiving table is equipped with multiple rows of support rods arranged at equal intervals, and each row of support rods is provided with a long strip support bar. The width of the support bar is smaller than the gap between the long strip blocks 62. Therefore, when the horizontal steaming bottom plate 6 is fixed on the turning table 103, the lifting mechanism works, and the support bar can pass through the gap between the long strip blocks 62 and fit with the blank surface on the other inner side of the turning table 103. After the turning table 103 is turned over, the lifting mechanism controls the support bar to descend, and the blank is placed on the horizontal steaming bottom plate 6. This method allows the lifting height of the lifting mechanism to be freely adjusted according to the size of the green body when transferring the green body from the vertical steaming curing bottom plate 8 to the horizontal steaming curing bottom plate 6, so that the support bar fits the green body, preventing the green body from failing to fit the horizontal steaming curing bottom plate 6 during transfer, resulting in green body transfer failure and damage.

[0102] It is worth mentioning that in order to prevent the horizontal steaming bottom plate 6 from moving on the bottom plate transport device 4 when the green body is clamped, thereby affecting the clamping accuracy, damaging the green body, or even causing the problem of green body clamping failure, the present embodiment is provided with a bottom plate positioning device 7. Figure 11 As shown, the bottom plate positioning device 7 includes a positioning frame 71 and a positioning cylinder 72. The positioning frame 71 is fixedly mounted on the base 1 and is provided with a through hole running through the top and bottom. The cylinder body of the positioning cylinder 72 is fixedly mounted on the positioning frame 71, and its piston rod extends upward and passes through the through hole. At the same time, a positioning hole 63 for the piston rod to pass through is provided on the side plate 61. In this embodiment, a single side plate 61 is provided with a plurality of positioning holes 63 along its length direction. When the horizontal steam curing bottom plate 6 reaches the predetermined position, the piston rod of the positioning cylinder 72 is extended upward and passes through the positioning hole 63 on the side plate 61, so that the horizontal steam curing bottom plate 63 stays at the predetermined position, preventing the horizontal steam curing bottom plate from moving during the process of clamping the blank, thereby causing the blank to be damaged and the blank to fail to be split. In order to further enhance the positioning effect of the horizontal steam curing bottom plate 6, a positioning device 7 is provided on the front and rear sides of the base 1 in this embodiment, respectively, so that the positioning of the horizontal steam curing bottom plate 6 is more stable.

[0103] In summary, the wet breaking machine is different from the traditional wet breaking machine. Through the lateral driving device 3, the upper breaking device 51, the lower breaking device 52 and the lifting device 53, the horizontally stacked blanks can be broken, which avoids the situation that when the traditional breaking machine breaks the vertically stacked blanks, the blanks have a large bonding force due to their own gravity, are easily damaged or even fail to break. The wet breaking machine has a clever structure, high breaking efficiency and precision, is not easy to damage the blanks, and improves the yield rate of concrete blocks or panels.

Without departing from the design concept of the present invention, various deformations and improvements made by those skilled in the art to the technical solutions of the present invention shall fall within the protection scope of the present invention.
