This, in turn, causes the liquid level plate, the first tension plate, and the second tension plate to extend and retract, working together with the mold to form a sealed splash guard space, effectively preventing concrete from splashing and reducing material waste.

[0028] 2. By activating the electric telescopic rod, the liquid level plate is pushed down to the bottom of the mold, so that the bottom of the liquid level plate is in contact with the inner bottom surface of the mold. The air inside the mold is discharged through the one-way valve, reducing air resistance during feeding and reducing the risk of splashing caused by hydraulic shock.

[0029] 3. By starting the motor, scraper one is driven to slide along slide bar three, which in turn drives scraper two to slide inside scraper one to adapt to the mold width, scraping the concrete at the top of the mold and the bottom of the liquid level plate into the storage tank, and then discharging it through the drain outlet, reducing cleaning costs and pollution to the production environment.

[0074] Referring to Figure 9 Figure 12 The plurality of transmission mechanisms 3 independently drive the splash plate one 201, the splash plate two 202, and the scraping mechanism 4, respectively. The transmission mechanism 3 includes a motor 301 and wire spools 302 fixedly sleeved on both ends of the motor 301. The motor 301 is a double-output shaft reduction motor with a self-locking function, which is a 58SGM3650 double-output shaft micro DC reduction motor produced by Li Jing Transmission Technology Co., Ltd. in Dongguan. Two wire spools 302 are fixedly sleeved on the two output shafts of the motor 301. One wire spool 302 is wound with a pull rope one 303, one end of which is fixed to the shaft of the wire spool 302. The other wire spool 302 is wound with a pull rope two 304, which is a high-strength steel wire rope. One end of the pull rope two 304 is fixed to the shaft of the wire spool 302.

The middle parts of the wire spools 302 and the pull rope two 304 respectively pass through the plurality of round holes one on the T-shaped groove one 18, the T-shaped groove three 20, and the T-shaped groove four 21.

[0075] When it is necessary to adjust the splash-proof mechanism 2 to adapt to the size of the mold 7, the control center sends instructions to the corresponding transmission mechanism 3. When the splash plate one 201 is driven, the motor 301 is started to make the two wire spools 302 rotate synchronously, so that one wire spool 302 retracts or extends the pull rope one 303, thereby pulling the middle part of the outer wall of the splash plate one 201 and driving the splash plate one 201 to slide in the T-shaped groove one 18 along the slide rod one 25. At the same time, the other wire spool 302 synchronously releases the pull rope two 304, so that the pulley 306 of the pull rope two 304 changes direction and extends or retracts from the round hole one 221 in the rectangular groove one 27 to the wire spool 302.

[0076] ​A plurality of pull ropes 303 are fixed to the middle of the outer wall of the splash guard 201 and the splash guard 202 and one side of the end of the scraping mechanism 4 away from the winding shaft 302. The second pull rope 304 is respectively threaded through the through hole 221 and the through hole 223 away from the middle of the circular hole.

The other rotating shaft 305 is located in the T-shaped groove 20. One end of the other rotating shaft 305 is fixed to the side wall of the T-shaped groove 20.

[0077] When the motor 301 rotates forward, the pull rope 303 is retracted and the pull rope 304 is released, driving the splash guard 201 to slide outward along the T-shaped groove and expand. When the motor 301 reverses, the pull rope 304 is retracted and the pull rope 303 is released, pulling the splash guard 201 back to the original position.

[0078] The outer side of the rotating shaft 305 is provided with a pulley 306. The end of the pull rope 304 away from the winding shaft 302 is threaded through the axis of the pulley 306. The end of the pull rope 304 away from the winding shaft 302 is respectively fixed to the inner wall of the splash guard 201 and the splash guard 202 close to the end of the splash guard 1. A plurality of pull ropes 303 and pull ropes 304 are respectively located in the T-shaped groove 18, the T-shaped groove 20, the T-shaped groove 21, the rectangular groove 27 and the rectangular groove 28. When the motor 301 rotates, one pull rope is retracted and the other pull rope is released at the same time, thereby pulling the splash guard 201, the splash guard 202 or the scraping mechanism 4 to reciprocate along the predetermined track.

[0079] The driving principle of the splash guard 202 and the scraping mechanism 4 is the same as that of the splash guard 201. The self-locking function of the motor 301 facilitates stopping and locking at any position, preventing displacement due to external force during pouring.

The middle part of the second pulling rope 304 of the driving scraping mechanism 4 penetrates the round hole three. The inner wall of the T-shaped slot three 20 is rotatably provided with a rotating rod 30 above the rotating shaft one 305.

The shape of the sliding block 403 is matched with the shape of the third sliding groove 216. The sliding block 403 slides inside the third sliding groove 216. When the splash-proof mechanism 2 adjusts the width, the second scraping plate 402 is linked to move together, so that the overall length of the scraping mechanism 4 is always matched with the width of the mold 7. The top end and the bottom end of the first scraping plate 401 and the second scraping plate 402 are provided with polyurethane scraping strips, which are used to effectively scrape the excess concrete on the top surface of the mold 7 and the bottom end of the liquid level plate 206 during movement, prevent the attachment of splashing materials, and push them into the storage tank 24.

[0082] At the same time, the second splash-proof plate 202 extends to push the second scraping plate 402 to slide inside the first scraping plate 401 to adapt to the size of the mold 7. The transmission mechanism 3 drives the second scraping plate 402 to slide along the first sliding rod 25 in the T-shaped slot three 20 to the direction away from the storage tank 24 between the first splash-proof plate 201 and the stretching plate 207, so as to prepare for scraping. After pouring is completed, the first electric telescopic rod 9 is retracted, the liquid level plate 206 assembly is pulled up to reset, and the second scraping plate 402 slides in the third sliding groove 216 of the second splash-proof plate 202 with the sliding block 403. The concrete that may overflow from the top end of the mold 7 and the bottom end of the liquid level plate 206 is scraped into the storage tank 24 and discharged through the sewage outlet.

[0083] The implementation principle of the concrete feeding splash-proof device for aerated board in the embodiment of the application is as follows: in use, the electric telescopic rod 2 pushes the splash-proof frame 1 to the two sides of the mold 7, so that the splash-proof frame 1 is attached to the adjacent wall of the mold 7; according to the size of the mold 7, the splash-proof plate one 201 and the splash-proof plate two 202 are respectively driven to slide along the splash-proof frame 1 by the multiple independent transmission mechanisms 3, to form a right-angle frame, and the liquid level plate 206, the stretching plate one 207 and the stretching plate two 208 are simultaneously extended and retracted, to adapt to the inner cavity of the mold 7, to form a bottom-closed semi-enclosed pouring space, then the electric telescopic rod one 9 is started to push the liquid level plate 206 to descend to the bottom of the mold 7, the air inside the mold 7 is discharged through the one-way valve 16, the electric valve 12 is opened to pour the concrete, the liquid level sensor 15 monitors and controls the real-time movement of the liquid level plate 206, after pouring is completed, the liquid level plate 206 is reset, the scraping mechanism 4 is driven by the transmission mechanism 3 to move along the top end of the mold 7 and the bottom end of the liquid level plate 206, to scrape the overflowed concrete into the storage groove 24, so as to complete the operations of splash-proof, precise feeding and cleaning.
