[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] Example 1

[0030] like Figures 1 to 2As shown, the embodiment of the present invention is a corrugated steel plate back membrane bag concrete grouting equipment, including a grouting machine 1; the end of the grouting machine 1 is fixedly connected to a screening barrel 11; the inner wall of the screening barrel 11 is fixedly connected to a No. 1 filter screen 12; the bottom end of the No. 1 filter screen 12 is fixedly connected to a vibration motor 13; the inner wall of the screening barrel 11 is fixedly connected to an elastic sealing gasket 14, and is located at the position of the vibration motor 13; the inner wall of the screening barrel 11 is fixedly connected to a No. 2 filter screen 15; the hole diameter of the No. 1 filter screen 12 is larger than the hole diameter of the No. 2 filter screen 15; when the grouting machine 1 is used to fill the membrane bag behind the corrugated steel plate with concrete, since the nozzles used for grouting equipment in different construction environments are different, and the concrete may contain stones of different sizes, when a small nozzle is used, the pre-mixed concrete is first poured into the screening barrel. The interior of the barrel 11 is filtered through the No. 1 filter plate 12, and a small amount of large stones are filtered at the end position of the No. 1 filter plate 12. The vibration motor 13 generates vibration to drive the No. 1 filter plate 12 to vibrate, and the concrete on the No. 1 filter plate 12 is shaken off. The concrete continues to fall through the No. 1 filter plate 12. The elastic sealing gasket 14 fixed to the side wall of the No. 1 filter plate 12 seals the storage position of the vibration motor 13. The concrete falls to the end position of the No. 2 filter plate 15 and is filtered again, and the medium-sized stones are filtered on the end face of the No. 2 filter plate 15. Most of the concrete continues to fall into the interior of the grouting machine 1, and is stirred and transported by the mixer to fill the membrane bag. The large and medium-sized stones are screened through multiple stages to prevent the large and medium-sized stones from clogging the nozzle, affecting normal construction, and causing damage to the machine in serious cases. It is also convenient for filling small cracks.

[0031] like Figures 1 to 3 As shown, the inner side wall of the screening barrel 11 is fixedly connected to a support frame 2; the end of the support frame 2 is fixedly connected to a servo motor 21; the output end of the servo motor 21 is fixedly connected to a rotating rod 22; the side wall of the rotating rod 22 is fixedly connected to a scraper cover 23; the side wall of the scraper cover 23 is fixedly connected to a No. 1 scraper 24; the side wall of the scraper cover 23 is fixedly connected to a No. 2 scraper 25; when some large particles of stone are screened and accumulated on the end surface of the No. 1 filter plate 12, the filtering efficiency of the No. 1 filter plate 12 is affected. As a result, the output end of the servo motor 21 is used to rotate the rotating rod 22, and the scraper No. 1 24 and the scraper No. 2 25 fixed to the side wall of the scraper cover 23 rotate and scrape from the end face and bottom face of the No. 1 filter screen plate 12 respectively, scraping and rotating the large-particle stones accumulated on the end face of the No. 1 filter screen plate 12 to prevent the stones from clogging the holes of the No. 1 filter screen plate 12. At the same time, the No. 2 scraper 25 is used to scrape the bottom face of the scraper cover 23 to reduce the amount of concrete adhering to the bottom face of the No. 1 filter screen plate 12 and affecting the filtration.

[0032] like Figures 2 to 3As shown, the inner wall of the No. 1 scraper 24 is fixedly connected to the No. 1 rubber baffle 3; the inner wall of the No. 1 scraper 24 is fixedly connected to the No. 2 rubber baffle 31, and is located below the No. 1 rubber baffle 3; the inner wall of the No. 1 scraper 24 is fixedly connected to the No. 3 filter screen 32; the hole diameter of the No. 3 filter screen 32 is the same as the hole diameter of the No. 1 filter screen 12; when some large particles of stone are filtered on the end surface of the No. 1 filter screen 12, the holes of the No. 1 filter screen 12 are blocked, and the No. 1 scraper 24 rotates with the scraper sleeve 23 to filter the particles. The large-particle gravel is scraped by the movement, and the large-particle gravel is squeezed by the No. 1 rubber baffle 3 and the No. 2 rubber baffle 31 as it rotates and enters the internal storage of the No. 1 scraper 24. The concrete will flow out of the No. 1 scraper 24 through the No. 3 filter screen 32, which has the effect of collecting the large-particle gravel. At the same time, when the interior of the No. 1 scraper 24 is blocked, the servo motor 21 can be used to rotate the No. 1 scraper 24 in the opposite direction, so that the stones blocked on the holes of the No. 3 filter screen 32 are shaken and fall off, and the No. 1 rubber baffle 3 and the No. 2 rubber baffle 31 are used to limit the storage of large stones.

[0033] like Figures 2 to 3 As shown, the side wall of the No. 3 filter screen plate 32 is fixedly connected with a fixed block 4; the inner side wall of the fixed block 4 is rotatably connected with a spiral rod 41; the side wall of the spiral rod 41 is fixedly connected with a scraper plate 42, and the scraper plate 42 fits the side wall of the No. 3 filter screen plate 32; when the No. 1 scraper 24 rotates the concrete to enter the interior of the No. 1 scraper 24, the concrete presses the spiral rod 41 to make the spiral rod 41 rotate, and the spiral rod 41 rotates on the inner side wall of the fixed block 4, and at the same time drives the scraper plate 42 fixed to the side wall to scrape the side wall of the No. 3 filter screen plate 32, so as to prevent large particles of stone from clogging the No. 3 filter screen plate 32 and affecting the flow filtration effect.

[0034] like Figures 2 to 4 As shown, the side wall of the rotating rod 22 is fixedly connected to the third scraper 5; the bottom end of the third scraper 5 is fixedly connected to the scraper 51, and the bottom surface of the scraper 51 is in contact with the end surface of the second filter screen plate 15; when medium-sized pebbles accumulate on the end surface of the second filter screen plate 15, the rotating rod 22 rotates to drive the third scraper 5 to scrape the end surface of the second filter screen plate 15, and cooperates with the scraper 51 fixed to the bottom end of the third scraper 5 to scrape the medium-sized pebbles, so as to prevent the medium-sized pebbles from clogging the holes of the second filter screen plate 15 and affecting the filtering effect of the second filter screen plate 15.

[0035] like Figures 1 to 5As shown, the side wall of the screening barrel 11 is fixedly connected to the collecting water tank 6; a foam block 61 is installed inside the collecting water tank 6; the end of the foam block 61 is fixedly connected to a sliding plate 62, and the sliding plate 62 is slidably connected to the inner wall of the collecting water tank 6; the inner wall of the screening barrel 11 is rotatably connected to a discharge baffle 63 through a torsion spring, and the bottom end of the discharge baffle 63 is in contact with the end face of the No. 2 filter screen plate 15; when a large amount of medium-sized granular stones accumulate on the end face of the No. 2 filter screen plate 15, the No. 3 scraper 5 rotates and scrapes with the rotating rod 22, and uses centrifugal force to scrape a large amount of medium-sized granular stones to the discharge baffle 63. The more stones accumulate at the discharge baffle 63, the more the discharge baffle is pushed. 63 is flushed open, and the discharge baffle 63 rotates with the torsion spring, and a large amount of stones fall into the internal storage of the collection water tank 6. After the stones fall into the collection water tank 6, the torsion spring drives the discharge baffle 63 to reset and block the channel again, which plays the role of storing and precipitating medium-sized grain stones. After the stones enter the collection water tank 6, the water level rises, and the foam block 61 drives the sliding plate 62 to float, which plays a warning role, making it easy to observe the stone storage amount inside the collection water tank 6. At the same time, the slope surface of the No. 2 filter plate 15 is used. When a large amount of concrete is accumulated at the discharge baffle 63, the concrete on the medium-sized grain stones will fall along the slope holes of the No. 2 filter plate 15, avoiding a large amount of concrete from entering the interior of the collection water tank 6.

[0036] like Figures 2 to 4 As shown, the inner wall of the No. 3 scraper 5 is fixedly connected with a metal baffle 7; the inner wall of the metal baffle 7 is rotatably connected with a rotating shaft 71, and the rotating shaft 71 is rotatably connected to the inner wall of the No. 3 scraper 5; the end of the rotating shaft 71 is fixedly connected with a stirring blade 72; when the No. 3 scraper 5 rotates to scrape the end face of the No. 2 filter screen plate 15, a large amount of medium-grained stones accumulate on the end face of the No. 2 filter screen plate 15, and the No. 3 scraper 5 scrapes the stones and concrete to accelerate the filtration, and a large amount of concrete mixed with stones impacts the side wall of the metal baffle 7, and washes the stirring blade 72 as it rotates with the rotating shaft 71, and the stirring blade 72 has a backflow effect. At the same time, the metal material of the metal baffle 7 vibrates when the stones hit, reducing a large amount of concrete adhering to the side wall of the metal baffle 7.

[0037] like Figures 2 to 4 As shown, the side wall of the rotating shaft 71 is fixed with a magnetic rotating plate 8; the inner wall of the third scraper 5 is fixed with multiple groups of magnetic blocks 81 through rubber plates; the magnetic rotating plate 8 and the magnetic blocks 81 can repel each other when they are close to each other; when the stirring blade 72 is rotated by a large amount of concrete, the rotating shaft 71 drives the magnetic rotating plate 8 to rotate on the inner wall of the third scraper 5, and when the magnetic rotating plate 8 approaches the magnetic block 81, they magnetically repel each other, and the magnetic rotating plate 8 continuously rotates to repel the magnetic block 81, and the magnetic block 81 then hits the side wall of the metal baffle 7, thereby enhancing the vibration effect of the metal baffle 7 and reducing a large amount of concrete adhering to the side wall of the metal baffle 7.

[0038] like Figures 2 to 5 As shown, the inner side wall of the screening barrel 11 is rotatably connected to a rotating plate 9; the end of the rotating plate 9 is fixedly connected to a No. 1 magnetic ball 91; the end of the No. 3 scraper 5 is fixedly connected to a No. 2 magnetic ball 92, and is located below the No. 1 magnetic ball 91; the interior of the No. 1 scraper 24 is fixedly connected to a No. 3 magnetic ball 93, and is located above the No. 1 magnetic ball 91; the No. 2 magnetic ball 92 and the No. 1 magnetic ball 91 can attract each other when they are close to each other; the No. 3 magnetic ball 93 and the No. 1 magnetic ball 91 can repel each other when they are close to each other; when a large amount of concrete adheres to the No. 1 filter plate 12 When the side wall of the No. 1 filter screen plate 12 is formed, the No. 1 scraper 24 and the No. 3 scraper 5 rotate with the rotating rod 22 and approach the No. 1 magnetic ball 91. The No. 2 magnetic ball 92 magnetically repels the No. 1 magnetic ball 91 and repels the No. 1 magnetic ball 91 upward. The No. 1 magnetic ball 91 rotates with the rotating plate 9 and hits the bottom surface of the No. 1 filter screen plate 12, which has the effect of vibrating the No. 1 filter screen plate 12 and shaking off the concrete adhered to the side wall of the No. 1 filter screen plate 12. In addition, the No. 3 magnetic ball 93 is magnetically attracted to the No. 1 magnetic ball 91, which accelerates the speed of the No. 1 magnetic ball 91 hitting the bottom surface of the No. 1 filter screen plate 12 and enhances the vibration effect of the No. 1 magnetic ball 91.

[0039] Example 2

[0040] like Figure 6 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a protective pad 94 is fixedly connected to the side wall of the No. 1 magnetic ball 91; the protective pad 94 is located at the end position of the No. 1 magnetic ball 91; when the No. 2 magnetic ball 92 rotates with the No. 3 scraper 5 and continuously approaches the No. 1 magnetic ball 91, it continuously drives the No. 1 magnetic ball 91 to collide with the bottom surface of the No. 1 filter plate 12. In order to prevent the No. 1 filter plate 12 from being worn due to long-term impact, the protective pad 94 is wrapped around the end position of the No. 1 magnetic ball 91. When the No. 1 magnetic ball 91 hits the No. 1 filter plate 12 again, it first collides with the protective pad 94 to avoid serious wear on the No. 1 filter plate 12 for a long time, thereby affecting the filtering effect.

[0041] Working principle: when using the grouting machine 1 to fill the membrane bag behind the corrugated steel plate with concrete, since the nozzles used by the grouting equipment are different in different construction environments, and the concrete will contain stones of different sizes, when using a small nozzle, first pour the pre-mixed concrete into the interior of the screening barrel 11, and filter it through the No. 1 filter plate 12, and filter a small amount of large stones at the end position of the No. 1 filter plate 12. The vibration motor 13 generates vibration to drive the No. 1 filter plate 12 to vibrate, and the concrete on the No. 1 filter plate 12 is shaken off. The concrete continues to fall through the No. 1 filter plate 12, and the elastic sealing gasket 14 fixed to the side wall of the No. 1 filter plate 12 serves to store the vibration motor 13. The sealing effect is achieved, and the concrete falls to the end position of the No. 2 filter plate 15 to be filtered again, and the medium-sized stones are filtered on the end surface of the No. 2 filter plate 15. Most of the concrete continues to fall into the interior of the grouting machine 1, and is stirred and transported by the mixer to fill the membrane bag. The large and medium-sized stones are screened at multiple stages to prevent the large and medium-sized stones from clogging the nozzle, affecting the normal construction, and causing damage to the machine in serious cases, and it is convenient to fill small cracks; when some large-sized stones are screened and accumulated on the end surface of the No. 1 filter plate 12, the filtering effect of the No. 1 filter plate 12 is affected, and the output end of the servo motor 21 is used to rotate the rotating rod 22, and the No. 1 scraper 24 and the No. 2 scraper 25 fixed to the side wall of the scraper cover 23 are respectively moved from The end face and bottom face of the No. 1 filter screen plate 12 are rotated and scraped to scrape and rotate the large-grained stones accumulated on the end face of the No. 1 filter screen plate 12 to prevent the stones from clogging the holes of the No. 1 filter screen plate 12. At the same time, the No. 2 scraper 25 is used to scrape the bottom face of the scraper cover 23 to reduce the amount of concrete adhering to the bottom face of the No. 1 filter screen plate 12 and affecting the filtration. When some large-grained stones are filtered on the end face of the No. 1 filter screen plate 12, the holes of the No. 1 filter screen plate 12 are clogged. The No. 1 scraper 24 is used to rotate with the scraper cover 23 to scrape the large-grained stones. The large-grained stones squeeze the No. 1 rubber baffle 3 and the No. 2 rubber baffle 31 as they rotate and enter the internal storage of the No. 1 scraper 24. The concrete will flow out through the No. 3 filter screen plate 32. The interior of the No. 1 scraper 24 has the effect of collecting large particles of stone. At the same time, when the interior of the No. 1 scraper 24 is blocked, the servo motor 21 can be used to reversely rotate the No. 1 scraper 24, so that the stones blocked on the holes of the No. 3 filter plate 32 are shaken and fall off, and the No. 1 rubber baffle 3 and the No. 2 rubber baffle 31 are used to limit and store large stones. When the No. 1 scraper 24 rotates the concrete into the interior of the No. 1 scraper 24, the concrete presses the screw rod 41 to make the screw rod 41 rotate. The screw rod 41 rotates on the inner wall of the fixed block 4, and at the same time drives the scraper plate 42 fixed to the side wall to scrape the side wall of the No. 3 filter plate 32, thereby preventing large particles of stone from clogging the No. 3 filter plate 32 and affecting the flow filtration effect.When medium-sized pebbles accumulate on the end face of the No. 2 filter screen plate 15, the rotating rod 22 rotates to drive the No. 3 scraper 5 to scrape the end face of the No. 2 filter screen plate 15, and cooperates with the scraper 51 fixed to the bottom end of the No. 3 scraper 5 to scrape the medium-sized pebbles to prevent the medium-sized pebbles from clogging the holes of the No. 2 filter screen plate 15 and affecting the filtering effect of the No. 2 filter screen plate 15; when a large amount of medium-sized pebbles accumulate on the end face of the No. 2 filter screen plate 15, the No. 3 scraper 5 rotates and scrapes with the rotating rod 22, and uses centrifugal force to scrape a large amount of medium-sized pebbles and drop them to the discharge baffle 63. The more pebbles accumulate on the discharge baffle 63, the more the discharge baffle 63 is flushed open, and the discharge baffle 63 rotates with the torsion spring, and a large amount of pebbles The stones fall into the collection tank 6 for storage. After the stones fall into the collection tank 6, the torsion spring drives the discharge baffle 63 to reset and block the channel again, which plays the role of storing and precipitating medium-sized stones. After the stones enter the collection tank 6, the water level rises, and the foam block 61 drives the sliding plate 62 to float, which plays a warning role, making it easy to observe the stone storage amount inside the collection tank 6. At the same time, the slope surface of the second filter plate 15 is used. When a large amount of concrete is accumulated at the discharge baffle 63, the concrete on the medium-sized stones will fall along the slope holes of the second filter plate 15, preventing a large amount of concrete from entering the collection tank 6. When the third scraper 5 rotates to scrape the end surface of the second filter plate 15, a large amount of medium-sized stones will fall. The stones accumulate on the end face of the No. 2 filter plate 15, and the No. 3 scraper 5 scrapes the stones and concrete to accelerate the filtration. A large amount of concrete mixed with stones impacts the side wall of the metal baffle 7 and washes the stirring blade 72 as it rotates with the rotating shaft 71. The stirring blade 72 has a backflow effect. At the same time, the metal material of the metal baffle 7 vibrates when the stones hit it, reducing the amount of concrete adhering to the side wall of the metal baffle 7; when the stirring blade 72 is washed and rotated by a large amount of concrete, the rotating shaft 71 drives the magnetic rotating plate 8 to rotate on the inner wall of the No. 3 scraper 5. When the magnetic rotating plate 8 approaches the magnetic block 81, they magnetically repel each other. The magnetic rotating plate 8 continuously rotates to repel the magnetic block 81, and the magnetic block 81 then hits the side wall of the metal baffle 7, enhancing the metal baffle 7 The vibration effect reduces the amount of concrete adhering to the sidewalls of the metal baffle 7. When a large amount of concrete adheres to the sidewalls of the first filter screen 12, the first and third scraper blades 24 and 5 rotate with the rotating rod 22, approaching the first magnetic ball 91. The second magnetic ball 92 magnetically repels the first magnetic ball 91, forcing it upward. The first magnetic ball 91 rotates with the rotating plate 9 and strikes the bottom surface of the first filter screen 12, vibrating the first filter screen 12 and shaking off the concrete adhering to the sidewalls of the first filter screen 12. Furthermore, the third magnetic ball 93 and the first magnetic ball 91 are magnetically attracted to each other, accelerating the speed at which the first magnetic ball 91 strikes the bottom surface of the first filter screen 12, thereby enhancing the vibration effect of the first magnetic ball 91.
