DETAILED DESCRIPTION

[0023] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0024] Embodiment 1, in combination with Figures 1 to 3 A grouting and vibrating device for aerated brick production, comprising a gantry 1, a grouting mechanism 2 and a vibrating mechanism 3; the gantry 1 is provided with a grouting mechanism 2 on the top, the grouting mechanism 2 comprises a rectangular grouting pipe 2-1 and a diverter gate 2-3, both sides of the bottom of the rectangular grouting pipe 2-1 are provided with oblique cuts, and the two oblique cuts are symmetrically arranged, and the positions corresponding to the two oblique cuts are respectively provided with diverter gates 2-3 for closing the two oblique cuts and the bottom opening of the rectangular grouting pipe 2-1, and the positions of the two sides of the diverter gate 2-3 near the top are connected to the rectangular grouting pipe 2-1 through a hinge shaft 2-2; the rectangular grouting pipe 2-1 is provided with a telescopic cylinder Ⅰ2-4 for controlling the opening or closing of the two diverter gates 2-3;

[0025] During the grouting operation, the bottoms of the two diverter gates 2-3 are driven to flip outwards through the telescopic cylinder I 2-4, and the tops of the two diverter gates 2-3 are flipped toward the inside of the rectangular grouting pipe 2-1, so that three channels are formed at the bottom of the rectangular grouting pipe 2-1. When the aerated brick slurry falls along the rectangular grouting pipe 2-1, part of the slurry falls directly into the aerated brick mold along the middle channel, and the remaining slurry is diverted to the two ends of the aerated brick mold under the guidance of the diverter gate 2-3, so that the slurry in the aerated brick mold is evenly distributed;

[0026] After the grouting operation is completed, the two diverter gates 2-3 are driven to close in the direction by the telescopic cylinder I 2-4, closing the two oblique cuts and the bottom opening of the rectangular grouting pipe 2-1 to prevent the residual slurry in the rectangular grouting pipe 2-1 from falling randomly;

[0027] It should be noted that the opening angles of the two diverter gates 2-3 can be controlled so that the channel openings on both sides of the bottom pipe opening of the rectangular grouting pipe 2-1 are larger than the opening in the middle, so that the slurry is preferentially diverted to the two ends of the aerated brick mold, thereby improving the effect of uniform distribution of the slurry in the aerated brick mold, thereby shortening the duration of subsequent vibration operations and improving grouting efficiency;

[0028] The vibration mechanism 3 includes a hanger 3-1 connected to the gantry 1 by lifting, and the hanger 3-1 is arranged with a plurality of vibration rods 3-2 in an array corresponding to the outer side of the grouting mechanism 2. The vibration generated by the vibration rods 3-2 can improve the fluidity of the slurry, so that the slurry in the aerated brick mold is evenly distributed, and can discharge the steam drum in the slurry, so that the slurry in the aerated brick mold is densely filled;

[0029] When in use, first move the aerated brick mold to the bottom of the grouting mechanism 2, and align the rectangular grouting pipe 2-1 with the center position of the aerated brick mold as much as possible; control the telescopic cylinder Ⅰ2-4 to open the two diverter gates 2-3 at the same time, and control the hanger 3-1 to descend, so that the vibrating rod 3-2 enters the aerated brick mold, and turn on the vibrating rod 3-2. During grouting, the vibrating rod 3-2 vibrates to make the slurry in the aerated brick mold dense and evenly distributed; after grouting, control the telescopic cylinder Ⅰ2-4 to close the two diverter gates 2-3, turn off the vibrating rod 3-2, and control the hanger 3-1 to rise, so that the vibrating rod 3-2 is higher than the aerated brick mold, and the aerated brick mold that has been filled with slurry can be removed, and the grouting operation of the next aerated brick mold can be carried out.

[0030] Embodiment 2, although the above embodiment can significantly improve the grouting efficiency, it is found in actual work that if the two diverter gates 2-3 cannot be opened or closed synchronously, the diverter effect and the sealing effect will be affected. The above embodiment cannot accurately control the opening angle of the two diverter gates 2-3, which will also affect the diverter effect. In order to solve the above technical problems, this embodiment is further improved;

[0031] Combined with Figures 1 to 3 , a grouting and vibrating device for aerated brick production, which is different from Example 1 in that, on the basis of Example 1, a connecting rod 2-5 is provided near the bottom of the outer side of the diverter gate 2-3, and the telescopic end of the telescopic cylinder I 2-4 is hinged to two connecting rods 2-7, and the other ends of the two connecting rods 2-7 are respectively hinged to the two connecting rods 2-5. The telescopic cylinder I 2-4 is actuated to control the two connecting rods 2-7 to act synchronously, so as to realize the synchronous opening or closing of the two diverter gates 2-3; the telescopic cylinder I 2-4 adopts the method as shown in the attached Figure 2 and3 The telescopic cylinder Ⅰ2-4 is installed in the manner shown, when the telescopic cylinder Ⅰ2-4 is extended, the two diverter gates 2-3 are controlled to be opened synchronously, and when the telescopic cylinder Ⅰ2-4 is shortened, the two diverter gates 2-3 are controlled to be closed synchronously. When the bottoms of the two diverter gates 2-3 are in contact with each other, the two diverter gates 2-3 can just close the two oblique cuts and the bottom opening of the rectangular grouting pipe 2-1;

[0032] The rectangular grouting pipe 2-1 is provided with a limit column 2-6 for limiting the flipping angle of the diverter gate 2-3, that is, the limit column 2-6 can limit the extension length of the telescopic cylinder I2-4, and indirectly control the opening angle of the two diverter gates 2-3.

[0033] Embodiment 3: There are various ways to control the lifting of the hanger 3-1 in the prior art. The simplest way is to set a telescopic cylinder on the top of the gantry 1 to directly drive the hanger 3-1 to lift. Although this structure is simple, the telescopic cylinder will increase the top height of the gantry 1. If the height of the plant is limited, this structure cannot be implemented. In addition, the hanger 3-1 is directly connected to the gantry 1 through the telescopic cylinder. When the vibrating rod 3-2 is in operation, part of the vibration energy will be transferred to the gantry 1, resulting in overall vibration, which will generate relatively large noise and affect the physical and mental health of the operator. In order to solve the above technical problems, this embodiment is further improved;

[0034] Combined with Figures 1 to 5 , a grouting and vibrating device for aerated brick production, based on embodiment 1 or 2, both sides of the gantry 1 are provided with a driving device 3-3 for driving the hanger 3-1 to rise and fall, and the driving device 3-3 can be a winch or a telescopic cylinder; the two driving devices 3-3 are correspondingly connected to the two ends of the hanger 3-1 through two steel cables 3-4, and the two ends of the top of the gantry 1 are respectively provided with a redirecting wheel 3-5 for redirecting the two steel cables 3-4. The driving devices 3-3 are located on both sides of the gantry 1, which can reduce the overall height and avoid interference with the top of the factory building. At the same time, the steel cables 3-4 can reduce vibration transmission and significantly reduce noise;

[0035] The vibrating rod 3-2 is connected to the hanger 3-1 via a flexible connector, which can also reduce vibration transmission and reduce the vibration amount of the hanger 3-1;

[0036] It should be noted that since the vibrating rod 3-2 is connected to the hanger 3-1 through a flexible connector, the hanger 3-1 will cause the vibrating rod 3-2 to shake randomly when it is raised or lowered quickly; therefore, the gantry 1 is provided with a stabilizing frame 3-6 at the bottom corresponding to the vibrating rod 3-2, and the stabilizing frame 3-6 is provided with a through hole that allows the vibrating rod 3-2 to move vertically through the position corresponding to the vibrating rod 3-2; when compaction operation is required, the vibrating rod 3-2 is lowered and passes through the through hole of the stabilizing frame 3-6 until the flexible connector enters the corresponding through hole The vibrating rod 3-2 is in the same position as the stabilizing frame 3-6, and the flexible connecting piece is not in contact with the stabilizing frame 3-6, so as to prevent the vibrating rod 3-2 from vibrating when working; when the compaction operation is finished, the hanger 3-1 drives the vibrating rod 3-2 to rise, and the vibrating rod 3-2 rises along the corresponding through hole, so as to prevent the vibrating rod 3-2 from shaking at will and colliding with each other, and it is necessary to ensure that when the vibrating rod 3-2 rises to the highest position, the bottom end of the vibrating rod 3-2 is still in the corresponding through hole of the stabilizing frame 3-6, so as to prevent the vibrating rod 3-2 from being separated from the restraint of the stabilizing frame 3-6 when it descends next time;

[0037] It should be noted that in actual work, it is found that when the vibrating rod 3-2 rises after the compaction operation is completed, the rod body of the vibrating rod 3-2 will carry some slurry. If the vibrating rod 3-2 does not work for a long time, the slurry carried by the rod body of the vibrating rod 3-2 will solidify and firmly adhere to the rod body of the vibrating rod 3-2, resulting in reduced working efficiency of the vibrating rod 3-2, or it will be unable to smoothly pass through the through hole of the stabilizing frame 3-6; therefore, a guide ring 3-7 is provided at the position corresponding to the through hole at the bottom of the stabilizing frame 3-6, and a necking portion corresponding to the diameter of the vibrating rod 3-2 is provided in the middle of the guide ring 3-7; the function of the guide ring 3-7 is to enable the vibrating rod 3-2 to smoothly enter the through hole of the stabilizing frame 3-6 when it rises. Since the guide ring 3-7 is provided with a necking portion in the middle, the slurry carried by the rod body of the vibrating rod 3-2 will be hindered by the necking portion of the guide ring 3-7 during the rising process of the vibrating rod 3-2, thereby achieving the purpose of cleaning the rod body of the vibrating rod 3-2.

[0038] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
