Description

Technical Field

[0001] This invention relates to the field of concrete forming technology, specifically to a concrete processing equipment and method for grinding limestone powder. Background Technology

[0002] Concrete forming is a critical step in concrete construction, involving pouring concrete into molds or supporting structures and ensuring its proper hardening.

[0003] Patent CN222431058U discloses a smoothing device for concrete slab production, relating to the technical field of concrete slab production equipment. Specifically, the device includes two symmetrically distributed sliding groove plates on the outside of a concrete slab production template. Each sliding groove plate has a groove inside, and a sliding block is fitted inside each groove. A drive motor is fixed to the end of one of the sliding groove plates, and a screw is connected to the output shaft of the drive motor. The screw passes through the sliding block, allowing it to slide within the groove of the sliding groove plate under the drive of the drive motor. This smoothing device, by utilizing the back-and-forth movement of the drive mechanism, enables the smoothing plate to move back and forth on the concrete template, vibrating and smoothing the concrete inside. This causes air and large particles in the concrete template to settle and compact, improving the production quality of the concrete slab.

[0004] However, when using the aforementioned device, excessive concrete is added during pouring. The excess concrete can be scraped off later. However, when the device scrapes off the excess concrete, the concrete falls directly onto the device or the ground, resulting in waste. At the same time, inserting a vibrator can increase the compaction of the concrete, but if the vibrator comes into contact with the reinforcing steel bars tied in the concrete, continuous vibration can easily cause the binding of the reinforcing steel bars to loosen, which can lead to displacement of the internal reinforcing steel bars after the concrete is formed, thus affecting the performance of the formed concrete. Therefore, a fine limestone powder concrete processing equipment and processing method are proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a grinding limestone powder concrete processing equipment and processing method to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a concrete processing equipment for grinding limestone powder, comprising:

[0007] The outer casing has a revolving door rotatably mounted on its front.

[0008] A support plate is installed on the inner wall of the outer casing, and a conveying roller is rotatably mounted on the inner wall of the support plate.

[0009] A hydraulic cylinder is fixedly connected to the top of the housing. A discharge frame is fixedly connected to the output end of the hydraulic cylinder. A telescopic rod is fixedly connected to the top of the discharge frame. A feed hose is fixedly connected to the right side of the discharge frame. Guide blocks are fixedly connected to the front and rear sides of the discharge frame.

[0010] A smoothing mechanism is disposed on the inner wall of the outer casing. The smoothing mechanism includes a scraper, which is rotatably connected to the inner wall of the outer casing via a torsion spring. A collection box is installed on the inner wall of the outer casing, and a guide plate is fixedly connected to the inner wall of the collection box. A support rod is rotatably connected to the inner wall of the outer casing via a torsion spring. A transmission rod is fixedly connected to the circumferential surface of the support rod. A collar is fixedly connected to one end of the transmission rod, and the collar is fitted onto the circumferential surface of the feed hose. The other end of the transmission rod contacts the top of the scraper. A lower rod and an upper rod are rotatably connected to the inner wall of the outer casing. A lower pulley and an upper pulley are fixedly connected to the circumferential surfaces of the lower rod and the upper rod, respectively. A rope is fixedly connected between the right side of the discharge frame and the top of the scraper. The circumferential surface of the rope contacts the circumferential surfaces of the lower pulley and the upper pulley. A limit block is fixedly connected to the inner wall of the outer casing.

[0011] The conveyor roller starts and moves the top mold below the discharge frame. At this time, the hydraulic cylinder starts and moves the discharge frame down and close to the mold. At this time, a metered amount of finely ground limestone powder concrete is discharged from the feed hose into the discharge frame. Then the concrete is discharged from the bottom of the discharge frame and enters the mold. The conveyor roller then moves the mold slowly to the right and allows the concrete to slowly fill the mold. After the discharge frame moves down, the scraper is reset downward by gravity and torsion spring through the cooperation of the rope with the lower pulley and the upper pulley. After the scraper rotates downward, it will contact the limit block and achieve complete reset. At this time, the left side of the scraper contacts the top surface of the mold. When the mold continues to move to the right, the scraper will scrape off the excess concrete on the top of the mold. The scraped concrete will fall on the top of the scraper and pass through the limit groove to prevent the concrete from sliding down again.

[0012] Preferably, the top of the conveying roller is provided with a mold, the circumferential surface of the feed hose is fixedly connected to the inner wall of the top of the outer shell, the top of the scraper is provided with multiple limiting grooves, the top of the telescopic rod is fixedly connected to the inner wall of the outer shell, and the limiting block is located on the movement trajectory of the scraper.

[0013] After the mold moves past the scraper, the hydraulic cylinder moves up to reset. At this time, the discharge frame is driven to reset by the hydraulic cylinder. The discharge frame pulls the rope and, through the cooperation of the lower pulley and the upper pulley, the rope pulls the scraper to rotate upward. After the scraper rotates, the left side will be higher than the right side. At this time, the concrete on the top of the scraper will slide down from the right side into the collection box and slide out of the device through the inclined guide plate in the collection box for recycling, thereby reducing concrete waste.

[0014] When the scraper rotates upward, it will push the transmission rod to rotate. The transmission rod will drive the collar to swing along the support rod. After the collar swings, it will drive the feed hose to move. The feed hose will push the concrete accumulated at the inner wall bend, so that it slides out of the feed hose and into the closed discharge frame. This prevents the concrete from accumulating at the bend of the feed hose and drying out after it is not used, which would lead to blockage at the bend of the feed hose.

[0015] Preferably, it further includes a guiding mechanism, the guiding mechanism including a rotating rod, the rotating rod being rotatably connected to the inner wall of the housing via a torsion spring, a connecting rod being fixedly connected to the inner wall of the top of the rotating rod, a sliding rod being slidably connected to the inner wall of the housing via a spring, a fixing rod being fixedly connected to the circumferential surface of the sliding rod, a push block being fixedly connected to the sliding rod, and a rotating roller being rotatably connected to the inner wall of the push block;

[0016] When the discharge frame moves downward, it causes the guide block to move downward. The guide block pushes the connecting rod to move through the inclined plane. The connecting rod drives the rotating rod to rotate. The rotating rod drives the fixed rod to move through the sliding groove on the inner wall. The fixed rod drives the sliding rod to move. The sliding rod drives the push block to move. The two push blocks come together and drive the rotating roller on its inner wall to contact the mold. This can position and guide the mold, ensuring that the mold is accurately located directly below the discharge frame. This prevents the concrete in the discharge frame from falling out of the mold, which would cause the product to fail to meet the process requirements after the concrete is formed.

[0017] Preferably, the inner wall of the rotating rod is provided with a sliding groove, the inner wall of the sliding groove is in contact with the circumferential surface of the fixed rod, and the circumferential surface of the connecting rod is in contact with the surface of the guide block.

[0018] Preferably, it also includes a vibration mechanism, which includes a helical rod rotatably connected to the inner wall of the support plate. The helical rod has a cross-shaped helical groove on its circumferential surface. A motor is installed on the side of the support plate, and the output end of the motor is fixedly connected to the helical rod.

[0019] Preferably, the circumferential surface of the spiral rod is movably connected to two movable plates, the inner wall of the movable plates is provided with a locking block, and the locking block is located in a cross-shaped spiral groove. The inner wall of the support plate is slidably connected to a movable block, the top of the movable block is fixedly connected to a vibration block, and the bottom of the movable plate is in contact with the inner wall of the support plate.

[0020] Preferably, a moving strip is fixedly connected between the two moving plates, a roller is installed on the top of the moving strip, an inclined block is fixedly connected to the inner wall of the moving block, the inclined block is located on the movement trajectory of the roller, and the bottom of the moving strip is in contact with the inner wall of the support plate.

[0021] While concrete is being discharged from the discharge frame, an external motor drives a auger to rotate. The auger, through the intersecting spiral grooves on its surface and the locking blocks on the inner wall of the moving plate, drives the moving plate to move back and forth. The moving plate drives the moving strip to move to the right, which in turn drives multiple rollers to move to the right. The multiple rollers push multiple inclined blocks upward through the inclined plane, and the multiple inclined blocks push the moving block upward evenly. The moving block then drives the vibrating block upward and into contact with the bottom of the mold.

[0022] Preferably, copper sheet one and copper sheet two are fixedly connected to the inner wall of the movable block, and an insulating plate is fixedly connected to the inner wall of the support plate. The insulating plate is located between copper sheet one and copper sheet two, and the front and rear sides of the insulating plate are in contact with the inner wall of the movable block.

[0023] This device controls whether the vibrating block is energized or not by connecting copper plate one, copper plate two, and the insulating plate. The circuit is completely controlled by the position of the moving block, eliminating the need for employees to operate the power switch. At the same time, when no power is needed, the insulating plate ensures absolute isolation between the copper plates, avoiding the risk of accidental short circuits or accidental energization.

[0024] Preferably, a mounting plate is fixedly connected to the top of the movable plate on the right, a diagonal rod is fixedly connected to the bottom of the mounting plate, the end of the diagonal rod away from the mounting plate is fixedly connected to the right side of the movable plate, and a slide rail is fixedly connected to the bottom of the mounting plate;

[0025] When the moving block moves upward, it will cause copper sheet one and copper sheet two to move upward and away from the insulating plate. After copper sheet one and copper sheet two leave the insulating plate, they will be reset by elastic force and make copper sheet one and copper sheet two contact and be energized. After being energized, the vibrating block vibrates. The vibration will be transmitted to the freshly poured concrete through the mold, thereby realizing simultaneous pouring and vibration to improve the compactness of the concrete. At the same time, by contacting the vibration source at the bottom of the mold, the vibration source can be prevented from directly contacting the steel bars placed in the mold, which can effectively prevent the steel wires binding the steel bars from loosening and improve the product quality after the concrete is formed.

[0026] When the scraper removes concrete from the top of the mold, a small amount of concrete at the last position will fall off after the scraper rotates and land on the surface of the two conveyor rollers below the limit block. At the same time, when the moving plate on the right moves, the moving plate drives the mounting plate to move, the mounting plate drives the support block to move, the support block drives the slider to move, and the slider drives the cleaning roller to move. When the moving plate moves left and right, it will drive the two cleaning rollers to move left and right, so that the two cleaning rollers intermittently contact the two conveyor rollers, thereby cleaning the concrete adhering to the surface of the two conveyor rollers and preventing the concrete from drying after adhering to the surface of the conveyor rollers, which would affect the operation of the subsequent conveyor rollers.

[0027] Preferably, a support block is fixedly connected to the top of the mounting plate, and a slider is slidably connected to the inner wall of the support block via a spring. A cleaning roller is rotatably connected to the inner wall of the slider via a connecting rod, and the circumferential surface of the cleaning roller contacts the circumferential surface of the conveying roller.

[0028] The cleaned concrete falls into the mounting plate, which has a ramp at the top. The ramp allows the cleaned concrete to slide to the right and be discharged from the support plate and the outer shell through a slide, preventing the cleaned concrete from remaining on the mounting plate and affecting subsequent use. After the device is used, the rotating door at the front of the outer shell can be opened, and the mounting plate and scraper can be cleaned simply by adding water, which is very convenient and quick.

[0029] A processing method for a limestone powder concrete processing equipment includes the following steps:

[0030] Step 1: The conveyor roller starts and moves the top mold to below the discharge frame. At this time, the hydraulic cylinder starts and drives the discharge frame to move down and close to the mold. At this time, the metered finely ground limestone powder concrete is discharged from the feed hose into the discharge frame. Then the concrete is discharged from the bottom of the discharge frame and enters the mold. After that, the conveyor roller drives the mold to move slowly to the right and allows the concrete to slowly fill the mold.

[0031] Step 2: After the discharge frame moves down, the scraper is reset downward by the rope in conjunction with the lower pulley and the upper pulley. After the scraper rotates downward, it will contact the limit block and achieve complete reset. At this time, the left side of the scraper will contact the top surface of the mold. When the mold continues to move to the right, the scraper will scrape off the excess concrete on the top of the mold. The scraped concrete will fall on the top of the scraper and pass through the limit groove to prevent the concrete from sliding down again.

[0032] Step 3: After the mold moves past the scraper, the hydraulic cylinder moves up to reset. At this time, the discharge frame will be driven to reset by the hydraulic cylinder. The discharge frame pulls the rope and, through the cooperation of the lower pulley and the upper pulley, the rope pulls the scraper to rotate upward. After the scraper rotates, the left side will be higher than the right side. At this time, the concrete on the top of the scraper will slide down from the right side into the collection box and slide out of the device through the inclined guide plate in the collection box for recycling.

[0033] Step 4: After the scraper rotates upward, it will push the transmission rod to rotate. The transmission rod drives the collar to swing along the support rod. After the collar swings, it will drive the feed hose to move. The feed hose will push the concrete accumulated at the inner wall bend, so that it slides out of the feed hose and into the closed discharge frame, preventing the concrete from accumulating at the feed hose bend and drying out after it is not used, which will lead to blockage at the feed hose bend.

[0034] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0035] 1. The grinding limestone powder concrete processing equipment and method involves a scraper that removes excess concrete from the top of the mold. The scraped concrete falls onto the top of the scraper and is prevented from sliding back down through a limiting groove. Simultaneously, the concrete on the top of the scraper slides down from the right side into a collection box and is recovered through an inclined guide plate in the collection box, thus reducing concrete waste. Furthermore, the swinging collar moves the feed hose, pushing the concrete accumulated at the bends on the inner wall of the feed hose, causing it to slide out of the feed hose and into a closed discharge frame. This prevents concrete from accumulating at the bends of the feed hose and drying out after use, which could lead to blockage at the bends.

[0036] 2. In this fine limestone powder concrete processing equipment and method, two push blocks converge and drive the rotating roller on its inner wall to contact the mold, thereby positioning and guiding the mold to ensure that the mold is accurately located directly below the discharge frame, preventing concrete from falling out of the mold from the discharge frame, which would result in the concrete product not meeting the process requirements after molding.

[0037] 3. This fine limestone powder concrete processing equipment and method involves a moving block that drives a vibrating block upwards to contact the bottom of the mold. Simultaneously, as the moving block moves upwards, it also moves copper plates one and two upwards away from the insulating plate. Once copper plates one and two are away from the insulating plate, they are spring-loaded back into place, bringing them into contact and energizing them. This energization causes the vibrating block to vibrate, which is then transmitted through the mold to the freshly poured concrete. This simultaneous pouring and vibration improves the concrete's density. Furthermore, the bottom of the mold contacts the vibration source, preventing direct contact between the vibration source and the reinforcing steel bars placed in the mold. This effectively prevents the steel wires binding the reinforcing steel bars from loosening, improving the quality of the finished concrete. The device controls the energization of the vibrating block through the interaction between copper plates one and two and the insulating plate, ensuring the circuit's continuity is entirely controlled by the position of the moving block. Employees do not need to operate the power switch separately. Additionally, when no power is required, the insulating plate ensures absolute isolation between the copper plates, preventing accidental short circuits or unintended energization.

[0038] 4. In this fine limestone powder concrete processing equipment and method, two cleaning rollers intermittently contact two conveying rollers, thereby cleaning the concrete adhering to the surfaces of these two conveying rollers. This prevents the concrete from drying out after adhering to the conveying rollers, which would affect the operation of subsequent conveying rollers. At the same time, the cleaned concrete falls into the mounting plate. The top of the mounting plate is equipped with an inclined surface, which allows the cleaned concrete to slide to the right and be discharged from the support plate and the outer shell through a slide rail, preventing the cleaned concrete from remaining on the mounting plate and affecting subsequent use. After the device is used, opening the rotating door at the front of the outer shell and simply adding water allows for cleaning of the mounting plate, scraper, and other structures, which is very convenient and quick.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figures 1-11 One embodiment of the present invention is: a concrete processing equipment for grinding limestone powder, comprising:

[0053] The outer casing 1 has a rotating door rotatably mounted on its front.

[0054] Support plate 2 is installed on the inner wall of the outer shell 1, and conveying roller 3 is rotatably installed on the inner wall of support plate 2.

[0055] Hydraulic cylinder 4 is fixedly connected to the top of housing 1. The output end of hydraulic cylinder 4 is fixedly connected to discharge frame 41. The top of discharge frame 41 is fixedly connected to telescopic rod 42. The right side of discharge frame 41 is fixedly connected to feed hose 43. The front and rear sides of discharge frame 41 are fixedly connected to guide block 44.

[0056] A smoothing mechanism 5 is installed on the inner wall of the outer casing 1. The smoothing mechanism 5 includes a scraper 51, which is rotatably connected to the inner wall of the outer casing 1 via a torsion spring. A collection box 52 is installed on the inner wall of the outer casing 1, and a guide plate 53 is fixedly connected to the inner wall of the collection box 52. A support rod 54 is rotatably connected to the inner wall of the outer casing 1 via a torsion spring, and a transmission rod 55 is fixedly connected to the circumferential surface of the support rod 54. A collar 56 is fixedly connected to one end of the transmission rod 55. The scraper 51 scrapes away excess concrete from the top of the mold. The scraped concrete falls onto the top of the scraper 51 and is prevented from sliding back down through a limiting groove. At the same time, the concrete on the top of the scraper 51 slides down from the right side. The collection box 52 is used for the collection device to slide out and be recycled through the inclined guide plate 53 in the collection box 52, thereby reducing concrete waste. The collar 56 is sleeved on the circumferential surface of the feed hose 43. The other end of the transmission rod 55 contacts the top of the scraper 51. The inner wall of the outer shell 1 is rotatably connected to the lower rod 58 and the upper rod 510 respectively. The circumferential surfaces of the lower rod 58 and the upper rod 510 are respectively fixedly connected to the lower pulley 59 and the upper pulley 511. The right side of the discharge frame 41 is fixedly connected to the top of the scraper 51. The circumferential surface of the rope 57 contacts the circumferential surfaces of the lower pulley 59 and the upper pulley 511. The inner wall of the outer shell 1 is fixedly connected to the limit block 512.

[0057] The bottom of the collection box 52 is slightly higher than the top of the mold, ensuring that the mold can pass between the conveyor roller 3 and the collection box 52 and exit the device. When the scraper 51 is scraping the concrete, the left side of the scraper 51 is slightly lower than the right side, and the left side of the scraper 51 is just in contact with the top of the mold, so that the scraper 51 is in a small angle tilt state. This ensures that after the concrete is scraped off by the scraper 51, most of the concrete is scraped onto the scraper 51, and only a small part falls off. This prevents the angle of the scraper 51 from being too large, which would cause most of the concrete to fall off and affect the subsequent concrete recycling effect.

[0058] After the collar 56 swings, it will drive the feed hose 43 to move. The feed hose 43 will push the concrete accumulated at the bend of the inner wall, causing it to slide out of the feed hose 43 and into the closed discharge frame 41. This prevents the concrete from accumulating at the bend of the feed hose 43 and drying out after it is not used, which would lead to blockage at the bend of the feed hose 43. The setting of the limiting groove can prevent the concrete from sliding to the left, but it can allow the concrete to slide to the right and fall into the collection box 52.

[0059] A mold is provided on the top of the conveyor roller 3, the circumferential surface of the feed hose 43 is fixedly connected to the inner wall of the top of the outer shell 1, multiple limiting grooves are provided on the top of the scraper 51, the top of the telescopic rod 42 is fixedly connected to the inner wall of the outer shell 1, and the limiting block 512 is located on the movement trajectory of the scraper 51.

[0060] A fine limestone powder concrete processing equipment further includes a guiding mechanism 6. The guiding mechanism 6 includes a rotating rod 61, which is rotatably connected to the inner wall of the outer shell 1 by a torsion spring. A connecting rod 62 is fixedly connected to the inner wall of the top of the rotating rod 61. A sliding rod 63 is slidably connected to the inner wall of the outer shell 1 by a spring. A fixing rod 64 is fixedly connected to the circumferential surface of the sliding rod 63. A push block 65 is fixedly connected to the sliding rod 63. A rotating roller is rotatably connected to the inner wall of the push block 65.

[0061] The two push blocks 65 converge and drive the rotating rollers on their inner walls to contact the mold, thereby positioning and guiding the mold to ensure that the mold is precisely located directly below the discharge frame 41, preventing the concrete in the discharge frame 41 from falling out of the mold and causing the product to fail to meet the process requirements after the concrete is formed.

[0062] The inner wall of the rotating rod 61 is provided with a sliding groove, the inner wall of the sliding groove is in contact with the circumferential surface of the fixed rod 64, and the circumferential surface of the connecting rod 62 is in contact with the surface of the guide block 44.

[0063] Working principle: The conveyor roller 3 starts and moves the top mold below the discharge frame 41. At this time, the hydraulic cylinder 4 starts and drives the discharge frame 41 down and close to the mold. At this time, the metered finely ground limestone powder concrete is discharged from the feed hose 43 into the discharge frame 41. Then the concrete is discharged from the bottom of the discharge frame 41 and enters the mold. Then the conveyor roller 3 drives the mold to move slowly to the right and allows the concrete to slowly fill the mold. After the discharge frame 41 moves down, the rope 57 cooperates with the lower pulley 59 and the upper pulley 511 to make the scraper 51 return to its original position by its own weight and torsion spring. After the scraper 51 rotates down, it will contact the limit block 512 and achieve complete reset. At this time, the left side of the scraper 51 contacts the top surface of the mold. When the mold continues to move to the right, the scraper 51 will scrape off the excess concrete on the top of the mold. The scraped concrete will fall on the top of the scraper 51 and pass through the limit groove to prevent the concrete from sliding down again. After the mold moves past the scraper 51, the hydraulic cylinder... 4. The upper part moves up to reset. At this time, the discharge frame 41 will be driven to reset by the hydraulic cylinder 4. The discharge frame 41 pulls the rope 57 and cooperates with the lower pulley 59 and the upper pulley 511 to make the rope 57 pull the scraper 51 to rotate upward. After the scraper 51 rotates, the left side will be higher than the right side. At this time, the concrete on the top of the scraper 51 will slide from the right side into the collection box 52 and slide out of the device through the inclined guide plate 53 in the collection box 52 for recycling, thereby reducing concrete waste. At the same time, after the scraper 51 rotates upward, it will push the transmission rod 55 to rotate. The transmission rod 55 drives the collar 56 to swing along the support rod 54. After the collar 56 swings, it will drive the feed hose 43 to move. The feed hose 43 will push the concrete accumulated at the inner wall bend, so that it slides out of the feed hose 43 and enters the closed discharge frame 41, preventing the concrete from accumulating at the bend of the feed hose 43 and drying out after it is not used, which will lead to blockage at the bend of the feed hose 43.

[0064] When the discharge frame 41 moves downward, it drives the guide block 44 to move downward. The guide block 44 pushes the connecting rod 62 to move through the inclined surface. The connecting rod 62 drives the rotating rod 61 to rotate. The rotating rod 61 drives the fixed rod 64 to move through the sliding groove on the inner wall. The fixed rod 64 drives the sliding rod 63 to move. The sliding rod 63 drives the push block 65 to move. The two push blocks 65 come together and drive the rotating roller on its inner wall to contact the mold, thereby positioning and guiding the mold to ensure that the mold is accurately located directly below the discharge frame 41, preventing the concrete in the discharge frame 41 from falling out of the mold, which would cause the product after the concrete is formed to not meet the process requirements.

[0065] Please see Figures 1-11Based on the above embodiments, in another embodiment of the present invention, a fine limestone powder concrete processing equipment further includes a vibration mechanism 7. The vibration mechanism 7 includes a spiral rod 71, which is rotatably connected to the inner wall of the support plate 2. The circumferential surface of the spiral rod 71 is provided with a cross spiral groove. A motor is installed on the side of the support plate 2, and the output end of the motor is fixedly connected to the spiral rod 71.

[0066] Two movable plates 74 are movably connected to the circumferential surface of the spiral rod 71. The inner wall of the movable plate 74 is provided with a locking block, and the locking block is located in the cross spiral groove. The inner wall of the support plate 2 is slidably connected to a movable block 72. The top of the movable block 72 is fixedly connected to a vibrating block 73. The bottom of the movable plate 74 is in contact with the inner wall of the support plate 2.

[0067] A moving strip 75 is fixedly connected between two moving plates 74. A roller 76 is installed on the top of the moving strip 75. An inclined block 77 is fixedly connected to the inner wall of the moving block 72. The inclined block 77 is located on the movement trajectory of the roller 76. The bottom of the moving strip 75 is in contact with the inner wall of the support plate 2.

[0068] Copper sheet 79 and copper sheet 710 are fixedly connected to the inner wall of the movable block 72 respectively. An insulating plate 78 is fixedly connected to the inner wall of the support plate 2. The insulating plate 78 is located between copper sheet 79 and copper sheet 710. The front and rear sides of the insulating plate 78 are in contact with the inner wall of the movable block 72.

[0069] By contacting the vibration source at the bottom of the mold, the vibration source can be prevented from directly contacting the steel bars placed in the mold, which can effectively prevent the steel wires binding the steel bars from loosening and improve the product quality after concrete molding. The device controls whether the vibration block 73 is energized through the copper sheet 79, copper sheet 710 and insulating plate 78, so that the circuit is completely controlled by the position of the moving block 72. The employee does not need to operate the power switch separately. At the same time, when no power is needed, the insulating plate 78 can ensure absolute isolation between the copper sheets, avoiding the risk of accidental short circuit or accidental power-on.

[0070] The moving block 72 drives the vibrating block 73 to move upward and contact the bottom of the mold. At the same time, when the moving block 72 moves upward, it will drive the copper sheet 79 and the copper sheet 710 to move upward and away from the insulating plate 78. When the copper sheet 79 and the copper sheet 710 leave the insulating plate 78, they will be reset by elastic force and make the copper sheet 79 and the copper sheet 710 contact and be energized. After being energized, the vibrating block 73 vibrates. The vibration will be transmitted to the freshly poured concrete through the mold, thereby realizing simultaneous pouring and vibration to improve the compactness of the concrete.

[0071] A mounting plate 711 is fixedly connected to the top of the right movable plate 74. A diagonal rod 712 is fixedly connected to the bottom of the mounting plate 711. The end of the diagonal rod 712 away from the mounting plate 711 is fixedly connected to the right side of the movable plate 74. A slide rail 713 is fixedly connected to the bottom of the mounting plate 711. A support block 714 is fixedly connected to the top of the mounting plate 711. Two cleaning rollers 716 intermittently contact two conveying rollers 3, thereby cleaning the concrete adhering to the surface of the two conveying rollers 3 and preventing the concrete from drying after adhering to the surface of the conveying rollers 3, which would affect the operation of the subsequent conveying rollers 3. A slider 715 is slidably connected to the inner wall of the support block 714 through a spring. The cleaning roller 716 is rotatably connected to the inner wall of the slider 715 through a connecting rod. The circumferential surface of the cleaning roller 716 contacts the circumferential surface of the conveying roller 3.

[0072] The cleaned concrete falls into the mounting plate 711. The top of the mounting plate 711 is provided with a slope. The cleaned concrete slides to the right through the slope and is discharged from the support plate 2 and the outer shell 1 through the slide 713, preventing the cleaned concrete from remaining on the mounting plate 711 and affecting subsequent use. After the device is used, the rotating door at the front of the outer shell 1 is opened. Simply add water to clean the mounting plate 711 and the scraper 51 and other structures, which is very convenient and quick.

[0073] A processing method for a limestone powder concrete processing equipment includes the following steps:

[0074] Step 1: The conveyor roller 3 starts and moves the top mold below the discharge frame 41. At this time, the hydraulic cylinder 4 starts and drives the discharge frame 41 down and close to the mold. At this time, the metered finely ground limestone powder concrete is discharged from the feed hose 43 into the discharge frame 41. Then the concrete is discharged from the bottom of the discharge frame 41 and enters the mold. Then the conveyor roller 3 drives the mold to move slowly to the right and allows the concrete to slowly fill the mold.

[0075] Step 2: After the discharge frame 41 moves down, the rope 57 cooperates with the lower pulley 59 and the upper pulley 511 to make the scraper 51 return to its original position by its own weight and torsion spring. After the scraper 51 rotates down, it will contact the limit block 512 and achieve complete reset. At this time, the left side of the scraper 51 contacts the top surface of the mold. When the mold continues to move to the right, the scraper 51 will scrape off the excess concrete on the top of the mold. The scraped concrete will fall on the top of the scraper 51 and pass through the limit groove to prevent the concrete from sliding down again.

[0076] Step 3: After the mold moves past the scraper 51, the hydraulic cylinder 4 moves up to reset. At this time, the discharge frame 41 will be driven to reset by the hydraulic cylinder 4. The discharge frame 41 pulls the rope 57 and cooperates with the lower pulley 59 and the upper pulley 511 to make the rope 57 pull the scraper 51 to rotate upward. After the scraper 51 rotates, the left side will be higher than the right side. At this time, the concrete on the top of the scraper 51 will slide from the right side into the collection box 52 and slide out of the device through the inclined guide plate 53 in the collection box 52 for recycling.

[0077] Step 4: After the scraper 51 rotates upward, it will push the transmission rod 55 to rotate. The transmission rod 55 drives the collar 56 to swing along the support rod 54. After the collar 56 swings, it will drive the feed hose 43 to move. The feed hose 43 will push the concrete accumulated at the inner wall bend, so that it slides out of the feed hose 43 and enters the closed discharge frame 41, preventing the concrete from accumulating at the bend of the feed hose 43 and drying out after it is not used, which will lead to blockage at the bend of the feed hose 43.

[0078] Working principle: While concrete is discharged from the discharge frame 41, the external motor drives the auger 71 to rotate. The auger 71, through the cooperation of the cross-shaped spiral grooves on its surface and the locking blocks on the inner wall of the moving plate 74, drives the moving plate 74 to move back and forth. The moving plate 74 drives the moving bar 75 to move to the right, which in turn drives multiple rollers 76 to move to the right. The multiple rollers 76 push multiple inclined blocks 77 upward through the inclined plane. The multiple inclined blocks 77 evenly push the moving block 72 upward. The moving block 72 drives the vibrating block 73 upward and into contact with the bottom of the mold. At the same time, when the moving block 72 moves upward, it also drives copper sheet 1 79 and copper sheet 2 710 upward and away from the insulating plate 78. When copper sheet 1 79 and copper sheet 2 710 leave the insulating plate 78, they will be reset by elastic force, causing copper sheet 1 79 and copper sheet 2 710 to contact and be energized. After being energized, the vibrating block 73 vibrates. Vibration is transmitted to the freshly poured concrete through the mold, thus achieving simultaneous pouring and vibration to improve the compactness of the concrete. At the same time, the bottom of the mold contacts the vibration source, preventing the vibration source from directly contacting the steel bars placed in the mold. This effectively prevents the steel wires binding the steel bars from loosening, improving the quality of the concrete after molding. When the discharge frame 41 stops discharging, the motor drives the screw rod 71 to continue rotating, causing the moving plate 74 to move to the left and reset. This device controls whether the vibrating block 73 is energized through the copper sheet 79, copper sheet 710 and insulating plate 78, so that the circuit is completely controlled by the position of the moving block 72. The employee does not need to operate the power switch separately. At the same time, when no power is needed, the insulating plate 78 can ensure absolute isolation between the copper sheets, avoiding the risk of accidental short circuit or accidental energization.

[0079] When the scraper 51 scrapes away the concrete at the top of the mold, a small amount of concrete at the last position will fall off after the scraper 51 rotates and land on the surface of the two conveyor rollers 3 below the limit block 512. At the same time, when the right-side moving plate 74 moves, the moving plate 74 drives the mounting plate 711 to move, the mounting plate 711 drives the support block 714 to move, the support block 714 drives the slider 715 to move, and the slider 715 drives the cleaning roller 716 to move. When the moving plate 74 moves left and right, it will drive the two cleaning rollers 716 to move left and right, so that the two cleaning rollers 716 intermittently contact the two conveyor rollers 3, thereby cleaning the two conveyor rollers. The concrete adhering to the surface of roller 3 is cleaned to prevent it from drying out and affecting the operation of subsequent rollers. The cleaned concrete falls into the mounting plate 711, which has a slope at the top. The slope allows the cleaned concrete to slide to the right and be discharged from the support plate 2 and the outer shell 1 through the slide 713, preventing the cleaned concrete from remaining on the mounting plate 711 and affecting subsequent use. After the device is used, the rotating door at the front of the outer shell 1 is opened, and the mounting plate 711 and scraper 51 are cleaned simply by adding water, which is very convenient and quick.

At this time, the hydraulic cylinder (4) is started and drives the discharge frame (41) to move down and close to the mold. At this time, the quantitatively ground limestone powder concrete is discharged from the feed hose (43) into the discharge frame (41). Then the concrete is discharged from the bottom of the discharge frame (41) and enters the mold. Then the conveyor roller (3) drives the mold to move slowly to the right and allows the concrete to slowly fill the mold. Step 2: After the discharge frame (41) moves down, it works with the lower pulley (59) and upper pulley (511) through the rope (57) so that the scraper (51) resets downward by its own weight and torsion spring. After the scraper (51) rotates downward, it will contact the limit block (512) and achieve complete reset. At this time, the left side of the scraper (51) contacts the top surface of the mold.

Step 4: After the scraper (51) rotates upward, it will push the transmission rod (55) to rotate. The transmission rod (55) drives the collar (56) to swing along the support rod (54). After the collar (56) swings, it will drive the feed hose (43) to move. The feed hose (43) will push the concrete accumulated at the inner wall bend, so that it slides out of the feed hose (43) and enters the closed discharge frame (41), preventing the accumulation of concrete at the bend of the feed hose (43) from drying out after it is not used, which will lead to blockage at the bend of the feed hose (43).
