Description
Technical Field
[0001] The utility model relates to the technical field of concrete grouting, in particular to concrete grouting equipment. Background Art
[0002] At present, with the rapid development of the construction industry, architects pay more attention to the deformation problems of expansion joints in building structures than ever before. Thermal expansion and contraction cause temperature rises and falls, foundation rises and falls, shaking at the top of high-rise buildings, earthquakes, etc., all of which cause the deformation of expansion joints in buildings. For this reason, R & D personnel have deeply studied the above problems, combined with the actual situation, fully considered and carefully developed, and absorbed the advanced design concepts and experiences in this regard abroad. As a result, the concrete grouting machine came into being. The concrete grouting machine is suitable for: leakage of expansion joints, leakage of settlement joints, leakage of subways, leakage of tunnels, leakage of dams, reinforcement of floors, cracks, and hollowing, indoor and outdoor spraying, spraying of cement mortar, spraying of dry mortar, and filling of concrete cement slurries.
[0003] A Chinese patent (the authorized announcement number is: CN 220059001 U, and the authorized announcement date is: November 21, 2023) proposed a grouting machine. This patented grouting machine does not require a prior mixer to stir the raw materials. It directly stirs in the grouting machine without pouring the well-stirred raw materials into the grouting machine, which improves the stirring efficiency. At the same time, it can effectively transport the raw materials to the conveying shaft, reducing the problem of blockage caused by raw material accumulation.
[0004] When the above patent stirs, the driving motor 401 drives the driving gear 402 to rotate. The rotating driving gear 402 drives the gear ring 403 to rotate. Then the gear ring 403 can drive the scraper 404 and the stirring rod 405 to rotate, so as to mix the raw materials evenly. Although the above patent has increased the stirring function of the concrete slurry, it only rotates the scraper and the stirring plate in the same direction for stirring, and the stirring method is relatively single. It does not increase the diverse stirring methods for the slurry, resulting in a decrease in the stirring efficiency. To improve the stirring efficiency of the filling machine for the cement slurry, we propose the concrete grouting equipment. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0029] Please refer to Figure 1-6 , the present invention provides a technical solution: a concrete grouting device, including a base 1, several rollers 2 are installed on the base 1, a conveying cylinder 3 is fixedly installed on the left side above the base 1, a feed hopper 4 is fixedly communicated above the conveying cylinder 3, a slurry conveying component is installed inside the conveying cylinder 3, a mixing cylinder 5 is installed above the base 1, a discharge pipe 26 is installed at the bottom of the mixing cylinder 5, and a slurry mixing component is installed inside the mixing cylinder 5.
[0030] During use, external cement slurry is put into the mixing cylinder 5, and the slurry mixing component in the mixing cylinder 5 mixes and stirs the mixed slurry. There are two stirring methods set in the slurry mixing component, which can improve the stirring efficiency of the mixed slurry. It not only does not require personnel to stir externally in advance before it can be used, but also can improve the stirring efficiency. The stirred mixed slurry enters the feed hopper 4 through the discharge pipe 26, and then the mixed slurry enters the conveying cylinder 3 under the action of gravity. The slurry conveying component in the conveying cylinder 3 outputs the slurry and fills it into the required position.
[0031] The slurry conveying component includes a motor 7, the motor 7 is fixedly installed on the base 1, the output end of the motor 7 is fixedly connected with a reducer, the output end of the reducer is connected with a conveying rod 20 through a coupling, the conveying rod 20 rotates and extends into the interior of the conveying cylinder 3, and a spiral conveying blade 18 is installed on the outer surface of the conveying rod 20.
[0032] When the motor 7 works, it will drive the conveying rod 20 to rotate. When the conveying rod 20 rotates, it will drive the spiral stirring blade 18 to rotate, and the spiral stirring blade 18 will convey the mixed slurry spirally.
[0033] The slurry stirring assembly includes a rotating pipe 16 which rotatably penetrates through a stirring cylinder 5. The top end of the rotating pipe 16 is fixedly communicated with an installation box 14. A plurality of installation pipes 13 are fixedly communicated with the installation box 14. A fixing rod 27 rotatably penetrates through the inside of the rotating pipe 16. The bottom of the fixing rod 27 is fixedly connected with a feeding hopper 4 through a bracket. The top end of the fixing rod 27 is fixedly connected with a first bevel gear 17. A transmission rod 10 is rotatably installed on the installation pipe 13. One end of the transmission rod 10 is fixedly connected with a second bevel gear 8. The second bevel gear 8 meshes with the first bevel gear 17. The other end of the transmission rod 10 is fixedly connected with a third bevel gear 19. A stirring rod 11 is rotatably installed on the installation pipe 13. The top end of the stirring rod 11 is fixedly connected with a fourth bevel gear 25. The fourth bevel gear 25 meshes with the third bevel gear 19. A plurality of stirring blades 15 are fixedly connected to the stirring rod 11. A scraping blade 12 is fixedly connected to the bottom of the stirring rod 11. The outer surface of the rotating pipe 16 is fixedly sleeved with a driven gear 28. A rotating rod 23 is rotatably installed at the bottom of the stirring cylinder 5. The outer surface of the rotating rod 23 is fixedly sleeved with a driving gear 24. The driving gear 24 meshes with the driven gear 28. The bottom of the rotating rod 23 is fixedly connected with a driven bevel gear 22. The outer surface of a conveying rod 20 is fixedly sleeved with a driving bevel gear 21. The driving bevel gear 21 meshes with the driven bevel gear 22.
[0034] When the motor 7 works, since the driving bevel gear 21 meshes with the driven bevel gear 22, it drives the rotating rod 23 to rotate. And since the driving gear 24 meshes with the driven gear 28, it further drives the rotating pipe 16, the installation pipe 13 and the stirring rod 11 to revolve. Also, since the fixing rod 27 is fixed on the feeding hopper 4, the first bevel gear 17 is fixed. When the installation pipe 13 works, the second bevel gear 8 will rotate along the fixed first bevel gear 17. At this time, the transmission rod 10 will rotate. And because the fourth bevel gear 25 meshes with the third bevel gear 19, the stirring rod 11 will rotate itself while revolving. Thus, through various stirring methods, the stirring efficiency of the mixed slurry can be improved. And this device can make the slurry stirring assembly and the slurry conveying assembly work simultaneously through a single motor 7, which can avoid setting multiple motor devices and effectively reduce the equipment cost.
[0035] Two mudguards 9 are installed on the base 1. The mudguards 9 can prevent mud during walking.
[0036] A filtering material rack is placed on the feeding hopper 4. The filtering material rack can filter the mixed slurry entering it to prevent larger stones from entering the inside of the conveying cylinder 3.
[0037] A number of heat dissipation fins are installed on the outer surface of the motor 7.
[0038] A handrail 6 is installed on the base 1. By cooperating with the rollers 2 through the handrail 6, it is convenient to push this filling equipment.
[0039] A manual valve is installed on the discharge pipe 26.
[0040] Working principle: During use, external cement slurry is put into the mixing drum 5. The slurry mixing component in the mixing drum 5 mixes and stirs the mixed slurry. Start the motor 7 to work, and the rotating rod 23 will rotate. Also, since the driving gear 24 meshes with the driven gear 28, it will drive the rotating pipe 16, the mounting pipe 13 and the stirring rod 11 to revolve. Moreover, since the fixed rod 27 is fixed on the feed hopper 4, the first bevel gear 17 remains stationary. When the mounting pipe 13 works, the second bevel gear 8 will rotate along the stationary first bevel gear 17. At this time, the transmission rod 10 will rotate. Also, since the fourth bevel gear 25 meshes with the third bevel gear 19, while the stirring rod 11 revolves, it will also rotate on its own. Thus, through various stirring methods, the stirring efficiency of the mixed slurry can be improved. There are two stirring methods set in the slurry mixing component, which can improve the stirring efficiency of the mixed slurry. It not only does not require personnel to stir externally in advance before it can be used, but also can improve the stirring efficiency.
[0041] After stirring, open the manual valve on the discharge pipe 26. The stirred mixed slurry enters the feed hopper 4 through the discharge pipe 26. Then, the mixed slurry enters the conveying cylinder 3 under the action of gravity. When the motor 7 works, it will drive the conveying rod 20 to rotate at the same time. When the conveying rod 20 rotates, it will drive the spiral stirring blade 18 to rotate. The slurry conveying component in the conveying cylinder 3 outputs the slurry and fills it into the required position.
[0042] With a single motor 7, this device can make the slurry mixing component and the slurry conveying component work simultaneously, avoiding the need to set multiple motor devices and effectively reducing the equipment cost.
