Technical Field
[0001] This utility model relates to the field of building construction tools, and in particular to a wall panel splicing and grouting tool that prevents mortar overflow. Background Technology
[0002] During the construction process, grouting is required when splicing wall panels. Mortar is used to fill the gaps between two adjacent wall panels, which effectively makes the connection between adjacent wall panels stronger, prevents wind, rain and moisture from penetrating the wall, and makes the wall surface clean, neat and beautiful. Grouting tools are used to fill the gaps between the wall panels with mortar.
[0003] However, most existing grouting tools require the operator to manually squeeze out the mortar. Manual squeezing can easily lead to uneven filling or overfilling, affecting the construction quality. Frequent squeezing also increases the operator's labor intensity and physical exertion. Therefore, a wall panel splicing grouting tool that prevents mortar overflow is proposed to solve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a wall panel splicing and grouting tool to prevent mortar overflow, comprising an installation component 1, a connecting block 2 fixedly connected to the top of the installation component 1, a motor 3 fixedly connected to the inner wall of the connecting block 2, a transmission shaft 4 fixedly connected to the output end of the motor 3, an eccentric wheel 5 fixedly connected to the other end of the transmission shaft 4, a connecting rod 8 slidably connected to the top through hole of the installation component 1, a spring 7 sleeved on the outside of the connecting rod 8, a limit plate 6 fixedly connected to one end of the connecting rod 8, and a piston 18 fixedly connected to the other end of the connecting rod 8. Piston 18 is externally fixedly connected to one-way valve 17, and one-way valve 17 is externally fixedly connected to conduit 16. The inside of mounting part 1 is provided with storage tank 14, and the inside of mounting part 1 is fixedly connected to partition plate 15. The inside of mounting part 1 is provided with movable groove 25, and one-way valve 19 is fixedly connected to the inner wall of movable groove 25. The bottom of mounting part 1 is fixedly connected to limit block 10, and the bottom of limit block 10 is slidably connected to discharge pipe 13. The inside of limit block 10 is installed with disassembly assembly, which is used to disassemble discharge pipe 13.
[0030] Furthermore, motor 3 is first started. The output end of motor 3 drives the transmission shaft 4 to rotate, which in turn drives the eccentric wheel 5 to rotate simultaneously. When the protrusion of the eccentric wheel 5 contacts the top of the limiting plate 6, the eccentric wheel 5 causes the limiting plate 6 to slide, which in turn causes the piston 18 to slide along the inner wall of the movable groove 25. At this time, one-way valve 17 is closed and one-way valve 19 is opened. Under the push of the piston 18, the mortar inside the movable groove 25 enters the discharge pipe 13, and then the discharge pipe 13 fills the gap with mortar. Meanwhile, the scraper 11 scrapes away excess mortar, effectively preventing mortar from overflowing from the seam. When the recess of the eccentric wheel 5 contacts the top of the limiting plate 6, the limiting plate 6, under the elastic force of the spring 7, drives the piston 18 to reset via the connecting rod 8. At this time, the one-way valve 17 opens and the one-way valve 19 closes. The mortar inside the storage tank 14 enters the interior of the movable tank 25 under the transport of the guide pipe 16. This process is repeated, and the automatic extrusion discharge effectively reduces the physical exertion of the operator, making the operation easier and more sustainable.
[0031] Reference Figure 1 and Figure 3 The disassembly assembly includes two pull rods 12. The pull rods 12 are slidably connected to the inside of the limiting block 10. A spring 21 is sleeved on the outside of the pull rods 12. A baffle 22 is fixedly connected to the other end of the pull rods 12. A locking block 23 is fixedly connected to the other side of the baffle 22. Two support grooves 20 are opened inside the limiting block 10. Two locking slots 24 are opened on the outside of the discharge pipe 13. The longitudinal section of the baffle 22 is square. The outside of the baffle 22 is slidably connected to the inner wall of the support groove 20. The shape of the locking block 23 matches the locking slot 24. The locking block 23 and the locking slot 24 are plugged into each other.
[0032] Furthermore, when it is necessary to disassemble the discharge pipe 13, pull the levers 12 to both sides to make the baffle 22 slide along the inner wall of the support groove 20, thereby causing the locking block 23 to slide simultaneously until the locking block 23 is completely retracted into the support groove 20. At this time, the discharge pipe 13 is separated from the limiting block 10, thus completing the disassembly of the discharge pipe 13. When it is necessary to install the discharge pipe 13, pull the levers 12 to both sides and repeat the above steps. At this time, the spring 21 is in a compressed state, which connects the outside of the discharge pipe 13 with the inside of the limiting block 10. When the inner wall of the limiting block 10 is in contact with the pull rod 12, the spring force of the second spring 21 causes the locking block 23 to engage with the inside of the slot 24, thus completing the installation of the discharge pipe 13. By disassembling the discharge pipe 13, the distribution of the filling mortar can be optimized, making the mortar distribution more uniform. When the pull rod 12 is pulled, the outer side of the baffle 22 slides along the inner wall of the support groove 20, ensuring the reliability of the baffle 22. By locking the locking block 23 with the slot 24, the discharge pipe 13 is further fixed, improving the stability of the discharge pipe 13.
[0033] Reference Figure 1 and Figure 2 The outer side of the eccentric wheel 5 is slidably connected to the top of the limiting plate 6; one end of the spring 7 is fixedly connected to the bottom of the limiting plate 6; the other end of the spring 7 is fixedly connected to the top of the mounting part 1; the outer side of the piston 18 is slidably connected to the inner wall of the movable groove 25; the outer side of the connecting rod 8 is slidably connected to the outer side of the partition plate 15; the material of the guide tube 16 is rubber; a scraper 11 is fixedly connected to the bottom of the mounting part 1, and the scraper 11 is set in an arc shape; a feed pipe 9 is fixedly connected to the outer side of the mounting part 1, and a cover plate is threadedly connected to the outer side of the feed pipe 9; the feed pipe 9 is connected to the storage tank 14.
[0034] Furthermore, the eccentric wheel 5 causes the limiting plate 6 to slide downwards, and the limiting plate 6 and the mounting part 1 limit the spring 7, making the force distribution of the spring 7 more uniform. When the outside of the eccentric wheel 5 contacts the limiting plate 6, the piston 18 slides along the inner wall of the movable groove 25, increasing the stability of the piston 18. The connecting rod 8 slides on the outside of the partition plate 15, making the structure more effective. The guide tube 16 is made of rubber, which is not easily deformed and effectively prevents mortar leakage. The scraper 11 can effectively scrape off excess mortar, effectively preventing mortar overflow and improving the aesthetics of the filling. The scraper 11 is designed in an arc shape, and when the scraper 11 is tilted, it can fully play its guiding role and prevent mortar from falling to the ground. The mortar enters the storage tank 14 through the feed pipe 9 to ensure the continuity of work. The cover plate prevents external debris from entering the interior of the storage tank 14 and avoids internal mortar leakage, which would cause mortar waste.
[0035] Working principle: First, start motor 3. Motor 3 drives eccentric wheel 5 to rotate through transmission shaft 4. When the protrusion of eccentric wheel 5 contacts the top of limit plate 6, under the traction of eccentric wheel 5, limit plate 6 drives connecting rod 8 to slide, which in turn drives piston 18 to slide simultaneously. At this time, one-way valve 17 closes and one-way valve 29 opens. Piston 18 pushes the mortar inside movable groove 25 into discharge pipe 13, and discharge pipe 13 fills the gap with mortar along the gap. At the same time, scraper 11 removes excess mortar. The mortar is scraped off to prevent it from overflowing into the joint and causing secondary pollution. When the recess of the eccentric wheel 5 contacts the top of the limiting plate 6, the limiting plate 6, under the elastic force of the spring 7, drives the piston 18 to reset through the connecting rod 8. At this time, the one-way valve 17 opens and the one-way valve 19 closes. The mortar inside the storage tank 14 enters the interior of the movable tank 25 under the conveying of the guide pipe 16. This process is repeated to accurately measure the amount of mortar used for joint filling. Through automatic extrusion, the material is discharged, effectively saving time and labor costs, thereby improving construction efficiency.
[0036] Additionally, when it is necessary to disassemble the discharge pipe 13, pull the pull rod 12 to both sides. The pull rod 12 drives the baffle 22 to slide, which in turn drives the locking block 23 to slide simultaneously until the locking block 23 is completely disengaged from the slot 24. At this time, the discharge pipe 13 is separated from the limiting block 10, thus completing the disassembly of the discharge pipe 13. When it is necessary to install the discharge pipe 13, pull the pull rod 12 to both sides and repeat the above steps. At this time, the second spring 21 is in a compressed state, which makes the outside of the discharge pipe 13 fit against the inner wall of the limiting block 10. Release the pull rod 12, and under the elastic force of the second spring 21, the locking block 23 is inserted into the inside of the slot 24, thus completing the installation of the discharge pipe 13. By disassembling the discharge pipe 13, the grouting tool can adapt to different construction environments and is more flexible.
[0037] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
