Description

Technical Field

[0001] The present invention relates to the technical field of building precast slabs, and specifically to an efficient manufacturing device for building precast slabs. Background Art

[0002] Currently, during the production process of existing building precast slabs, the following steps are required: 1. Mold cleaning; 2. Mold installation; 3. Mesh truss processing; 4. Mesh placement; 5. Embedded material; 6. Concrete batching; 7. Concrete post-treatment; 8. Precast slab curing; 9. Precast slab demolding; 10. Hoisting and conveying.

[0003] During the process of concrete batching for the precast slab, the component model, the information on the side of the trolley, and the mold number are confirmed. Subsequently, the batching plant is called for materials. When the concrete reaches the feeder, an appropriate discharge port is selected according to the slab width for discharging.

[0004] However, after the concrete falls into the feeder and then drops from the feeder to the mold, due to the certain viscosity of the agitated concrete, during the process of discharging through the discharge port onto the mold, although the feeder moves along the mold synchronously, there will still be a phenomenon of excessive local concrete accumulation and insufficient local concrete on the mold. If the concrete is not raked manually, it will cause the mold to spill materials during subsequent vibration and result in insufficient concrete usage for the precast slab, thereby causing the precast slab to fail to meet the standards. For this reason, we propose an efficient manufacturing device for building precast slabs. Summary of the Invention

Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0045] Please refer to Figures 1 to 3 , a high-efficiency building precast slab manufacturing device, including a loading shell 1 for loading concrete and a blanking cylinder 2 installed at the bottom of the loading shell 1. The loading shell 1 moves above the precast slab manufacturing mold along a truss. The blanking cylinder 2 is communicated with the loading shell 1. The loading shell 1 is filled with concrete, which is used for pouring at the mold. And a blanking port 21 is provided at the bottom of the blanking cylinder 2. A rotating shaft 3 is provided inside the blanking cylinder 2, and a plurality of rotating plates 4 are equidistantly arranged outside the rotating shaft 3. A protective shell 22 is provided outside the blanking cylinder 2, and a servo motor 23 for driving the rotating shaft 3 is installed at the protective shell 22. The rotating shaft 3 penetrates through the blanking cylinder 2, and the rotating shaft 3 is rotationally connected with the blanking cylinder 2. Thus, when the servo motor 23 operates, the rotating shaft 3 further rotates. And when the rotating shaft 3 rotates, the plurality of rotating plates 4 can rotate synchronously, thereby driving the concrete falling from the loading shell 1 to be discharged;

[0046] Please refer to Figures 4 to 5 , a moving scraping mechanism 5 is provided between the plurality of rotating plates 4. While the moving scraping mechanism 5 rotates with the rotating plates 4 and the rotating shaft 3, it makes the concrete evenly distributed between the rotating plates 4;

[0047] Adjusting discharge mechanisms 6 are provided on both sides of the moving scraping mechanism 5. The adjusting discharge mechanisms 6 adjust the discharge size of the blanking port 21. That is, in this example, the discharge port is set as a continuous length discharge port. This kind of setting can enable the concrete to fully fall from the discharge port without blocking the concrete, thereby ensuring the stability of the concrete falling;

[0048] Please refer to Figures 6 to 8 , the adjusting discharge mechanism 6 includes baffles 61. There are two baffles 61. The two baffles 61 are respectively slidably sleeved at both ends of the plurality of rotating plates 4. Two connecting plates 62 are provided on the sides of the two baffles 61 away from each other, and locking bolts 63 are provided on the connecting plates 62, and the locking bolts 63 are locked with the corresponding rotating plates 4.

[0049] A plurality of first scraping strips 64 and second scraping strips 65 are respectively fixedly installed on the sides of the two baffles 61 close to each other. The first scraping strips 64 and the second scraping strips 65 are staggered, and the concrete inside the blanking cylinder 2 is scraped between the first scraping strips 64 and the second scraping strips 65 and the corresponding rotating plates 4;

[0050] Specific implementation process: When adjusting the size of the discharge port, the locking bolts 63 at the connecting plates 62 on one side of the baffle 61 are respectively turned, so that the locking bolts 63 are disengaged from the baffle 61. Subsequently, the two baffles 61 are moved a certain distance towards each other along the two ends of the plurality of rotating plates 4. At this time, the size of the material discharge port 21 between the rotating plates 4 can be adjusted to the set length. At the same time, the length of the material discharge port 21 at this time is the length of the corresponding mold. Subsequently, the locking bolts 63 can be tightened to fix the baffle 61 relative to the plurality of rotating plates 4. At the same time, in this embodiment, while the distance between the two baffles 61 is adjusted synchronously, since the first scraping strip 64 and the second scraping strip 65 are respectively fixedly connected to the two baffles 61, the first scraping strip 64 and the second scraping strip 65 can move relative to each other. At the same time, the first scraping strip 64 and the second scraping strip 65 are slidably connected to the gap between the rotating plate 4 and the material discharge cylinder 2, so as to ensure that while the baffle 61 rotates synchronously with the rotating plate 4, the first scraping strip 64 and the second scraping strip 65 cooperate with the rotating plate 4 synchronously to scrape the concrete on the inner wall of the material discharge cylinder 2;

[0051] Please refer to Figures 9 to 12 , the moving scraping mechanism 5 includes a rotating rod 51, a synchronous rotating mechanism 8 and a moving stirring mechanism 9. There are a plurality of rotating rods 51, and the plurality of rotating rods 51 are respectively located between the two rotating plates 4. Two guiding strips 511 are arranged on the outer side of the rotating rod 51. Rotating sleeves 52 are slidably sleeved at both ends of the rotating rod 51, and guiding grooves are arranged at the positions of the rotating sleeves 52 corresponding to the two guiding strips 511;

[0052] The rotating sleeve 52 penetrates through the baffle 61, and the rotating sleeve 52 is rotatably connected to the baffle 61;

[0053] The synchronous rotating mechanism 8 is arranged at one end inside the material discharge cylinder 2, and the synchronous rotating mechanism 8 is used to synchronously drive the plurality of rotating rods 51;

[0054] The moving stirring mechanism 9 includes a fixed block 91, a moving block 92 and a side block 93. The fixed block 91 is located on the Y axis of the material discharge cylinder 2, and the fixed block 91 is fixedly installed on the rotating rod 51. There are a plurality of moving blocks 92, and the plurality of moving blocks 92 are respectively equidistantly distributed on both sides of the fixed block 91, and the plurality of moving blocks 92 are slidably sleeved on the outer sides of the rotating rod 51 and the guiding strips 511. There are two side blocks 93, and the two side blocks 93 are respectively located at both ends of the rotating rod 51, and the two side blocks 93 are fixedly sleeved on the outer side of the rotating sleeve 52;

[0055] One sides of the fixed block 91, the moving block 92 and the side block 93 are respectively rotatably connected with connecting support rods 94 through rotating shafts. Two adjacent connecting support rods 94 are staggered, and the connecting support rods 94 are hinged to each other through pins;

[0056] On both sides of the fixed block 91 and the multiple moving blocks 92, there are two sets of stirring and scraping members 95. At the same time, in this embodiment, two rotating shafts are provided on the fixed block 91, so that connecting rods 94 are rotatably connected at both rotating shafts. At the same time, one end of the connecting rod 94 is hinged to the connecting rod 94 at the adjacent moving block 92 through a pin shaft;

[0057] Please refer to Figures 10 to 12 , the stirring and scraping member 95 includes a sliding sleeve 951, a connecting spring 952, a sliding rod 953 and a scraping plate 954. The sliding sleeve 951 is fixedly installed on the moving block 92 or the fixed block 91. One end of the connecting spring 952 is fixedly connected to the inner wall of the sliding sleeve 951, and the other end of the connecting spring 952 is fixedly connected to the sliding rod 953. The sliding rod 953 slidably penetrates one end of the sliding sleeve 951, and the sliding rod 953 is in fit connection with the sliding sleeve 951. The ends of the multiple sliding rods 953 away from the moving block 92 or the fixed block 91 are fixedly connected to each other with the scraping plate 954;

[0058] Specifically: when the distance between the two baffles 61 is adjusted, the side block 93 is synchronously driven to move by rotating the sleeve 52. When the side block 93 moves relative to the moving block 92, due to the pin shaft hinge between the multiple connecting rods 94, further synchronous rotation occurs between the multiple connecting rods 94, further driving the equal-distance adjustment of the distance between the multiple moving blocks 92. Thus, it is ensured that after the distance is adjusted, the multiple moving stirring mechanisms 9 between the baffles 61 can be synchronously adjusted, achieving the function of rotating and stirring the concrete between the rotating plates 4;

[0059] The moving stirring mechanism 9 is installed on the rotating rod 51, and while the rotating rod 51 rotates, the concrete between the two rotating plates 4 is stirred and mixed.

[0060] Please refer to Figures 4 to 5 , the synchronous rotation mechanism 8 includes a sealing shell 81, an internal gear ring 82, a connecting block 83 and a rotating gear 84. The sealing shell 81 is rotatably connected to one end inside the blanking cylinder 2 through a sealing bearing, and the sealing shell 81 is fixedly sleeved outside the rotating shaft 3. One end of the sealing shell 81 close to the blanking cylinder 2 is open. There are multiple connecting blocks 83. One side of the multiple connecting blocks 83 is fixedly connected to the inner wall of the blanking cylinder 2, and the internal gear ring 82 is fixedly connected to the multiple connecting blocks 83;

[0061] One end of each of the multiple rotating rods 51 penetrates through the sealing shell 81, and the rotating rod 51 is fixedly connected to the sealing shell 81. There are multiple rotating gears 84. The multiple rotating gears 84 are meshed with the internal gear ring 82, and the rotating gear 84 is fixedly connected to the rotating rod 51;

[0062] Specific implementation process: While the rotating shaft 3 drives multiple rotating plates 4 to rotate along the blanking cylinder 2, the concrete located inside the loading shell 1 synchronously falls between two adjacent rotating plates 4. At the same time, the rotating rod 51 rotates between two baffles 61 through the rotating gear 84. When the rotating rod 51 rotates, it synchronously drives multiple moving blocks 92 and fixed blocks 91 thereon to rotate, further enabling the sliding sleeves 951 and sliding rods 953 on the moving blocks 92 and fixed blocks 91 to rotate relative to the cavity between two rotating plates 4, further realizing the function of stirring and mixing the concrete. At the same time, under the action of centrifugal force, the connecting springs 952 of multiple sliding rods 953 are stretched, and multiple sliding rods 953 move outward along the sliding sleeves 951, so that the scraping plates 954 between multiple sliding rods 953 rotate along between two rotating plates 4, realizing the function of scraping the concrete between two rotating plates 4, and further ensuring that the concrete can fully fall onto the mold;

[0063] A plastering mechanism 7 is provided at a position outside the loading shell 1 on the rotating shaft 3, and the plastering mechanism 7 cooperates with the rotating shaft 3 to evenly redistribute the uniformly falling concrete onto the precast slab manufacturing mold again.

[0064] The plastering mechanism 7 includes an arc-shaped plastering plate 71, a connecting member 72, and a reciprocating driving member 73.

The reciprocating driving member 73 is used to drive the connecting member 72, and the reciprocating driving member 73 is connected to the rotating shaft 3.

[0065] The connecting member 72 includes a mounting plate 721, a connecting rod 722, a top plate 723, a buffer spring 724, a support block 725, and a roller 726.

The top plate 723 is fixedly installed at the top of the connecting rod 722. Both ends of the buffer spring 724 are fixedly connected to the top plate 723 and the mounting plate 721 respectively. The support block 725 is fixedly installed on the top plate 723, and the roller 726 is rotatably connected to one side of the support block 725;

[0066] Specific implementation process: In this embodiment, the arc-shaped material spreading plate 71 is provided with an opening corresponding to the position of the steel bars on the mold, which does not affect the movement of the arc-shaped material spreading plate 71. At the same time, during use, the arc-shaped material spreading plate 71 moves synchronously along the mold through the movement of the loading shell 1. At the same time, the stirred concrete can smoothly fall onto the mold. Subsequently, the arc-shaped material spreading plate 71 levels the concrete synchronously. And while rotating along with the rotating shaft 3, due to the action of the reciprocating driving member 73 and at the same time under the action of the buffer spring 724, the roller 726 moves up and down along the outer side of the blanking cylinder 2, so that the arc-shaped material spreading plate 71 vibrates and levels the concrete on the mold, further enabling the concrete to be evenly distributed on the mold and achieving the effect of leveling the surface of the concrete.
