Description

Technical Field

[0001] This application relates to the field of concrete test block molding equipment, and in particular to an automatic concrete test block molding device. Background Technology

[0002] The strength evaluation of concrete test blocks is to assess the problems that occur during the sample delivery process of concrete test blocks in accordance with the "Code for Acceptance of Construction Quality of Concrete Structures" and the "Standard for Testing and Evaluation of Concrete Strength". Sample delivery for civil engineering testing is a major way to reflect the quality of civil engineering projects, and the delivery of concrete test blocks is an important part of civil engineering testing.

[0003] However, the molding of concrete test blocks mainly relies on manual operation, which is inefficient, labor-intensive, and makes it difficult to ensure the consistency of molding quality. Summary of the Invention

[0004] To reduce manual operation and improve work efficiency, this application provides an automatic concrete test block loading device.

[0005] The automatic concrete test block loading device provided in this application adopts the following technical solution: An automatic concrete test block loading device includes a feeding hopper, a support frame below the feeding hopper, multiple support rollers on the support frame, a mold placed on the support rollers, a vibration scraping mechanism on the feeding hopper, and a conveying mechanism for conveying the mold on the outside of the support frame, the conveying mechanism being connected to a mold cleaning mechanism.

[0006] By adopting the above technical solution, the mold moves to the bottom of the support frame under the action of the conveying mechanism, and the hopper fills the mold with concrete. During the concrete filling process, the vibrating scraping mechanism vibrates the mold, so that the concrete is evenly distributed in the mold. After the mold is full of concrete, the conveying mechanism conveys the mold away from the hopper again, and at the same time, the vibrating scraping mechanism scrapes the upper surface of the mold. This realizes automatic concrete filling and scraping. At the same time, the mold after demolding is cleaned by the mold cleaning mechanism, reducing manual labor, reducing labor intensity, and improving the production efficiency of concrete test blocks.

[0007] Optionally, the vibrating scraping mechanism includes a vibrating roller rotatably connected to a support frame. The rotation axis of the vibrating roller is eccentrically set, and the rotating roller abuts against the bottom of the mold. The lower end of the hopper is provided with an hourglass-shaped discharge port. Both sides of the middle part of the discharge port are provided with relief grooves. A rotating rod is rotatably connected in the relief groove. Multiple evenly distributed fan blades are provided on the rotating rod. A transmission component is provided between the rotating rod and the vibrating roller.

[0008] By adopting the above technical solution, when the concrete falls from the hopper, the concrete drives the fan blades and the rotating rod to rotate. The rotating rod drives the vibrating roller to rotate through the transmission component. The vibrating roller repeatedly vibrates the mold during the rotation, thereby causing the mold to shake and making the concrete inside the mold uniform.

[0009] Optionally, the transmission component includes a transmission rod, one end of which is connected to the vibrating roller via a gear set, and the other end of which is connected to the rotating rod via a gear set. The support frame is also equipped with a drive motor for driving the vibrating roller.

[0010] By adopting the above technical solution, the rotating rod drives the vibrating roller to rotate through the gear set and transmission rod during the rotation process. When the concrete inside the hopper stops moving, the drive motor drives the vibrating roller to rotate and continue vibrating the mold.

[0011] Optionally, a connecting rod is rotatably connected to one side of the discharge port, and a vertical baffle is provided on the connecting rod. An inclined scraper is also provided on the side of the baffle closer to the mold. The scraper is rotatably connected to the connecting rod, and a torsion spring is provided between the scraper and the baffle to connect the two.

[0012] By adopting the above technical solution, during the movement of the mold, it first contacts the baffle and squeezes the baffle, thereby causing the connecting rod to rotate until the scraper abuts against the upper surface of the mold. This adapts to molds of different heights. After the scraper abuts against the upper surface of the mold, if the baffle is still squeezed by the mold, the baffle continues to drive the connecting rod to rotate, and the scraper continues to abut against the upper surface of the mold. At this time, the torsion spring is deformed by force, causing the scraper and the baffle to rotate relative to each other, thus satisfying the normal movement of the mold.

[0013] Optionally, a recovery pipe is provided below the support roller, and the recovery pipe is disposed on the support frame.

[0014] By adopting the above technical solution, the concrete scraped off the mold by the scraper falls through the support roller and reaches the recycling pipe, thereby recycling the excess concrete and reusing it.

[0015] Optionally, the conveying mechanism includes an infeed conveyor belt and an outfeed conveyor belt disposed on the outside of the support frame. An infeed hydraulic cylinder is disposed on the side of the infeed conveyor belt away from the support roller. An outfeed hydraulic cylinder is also disposed on the side of the support frame away from the outfeed conveyor belt. The scraper is located on the side of the discharge hopper close to the outfeed hydraulic cylinder. The direction of the infeed hydraulic cylinder is perpendicular to the direction of the outfeed hydraulic cylinder.

[0016] By adopting the above technical solution, when the mold feeding conveyor belt moves the empty mold to one side of the support frame, the mold feeding hydraulic cylinder pushes the empty mold to the bottom of the discharge hopper. After the mold is filled with concrete, the mold discharge hydraulic cylinder drives the mold to leave the discharge hopper and reach the mold discharge conveyor belt, thereby completing the mold feeding and discharging work.

[0017] Optionally, the mold cleaning mechanism includes a cleaning box with a drain plate at the top and an inclined guide plate inside. The lower end of the guide plate extends out of the cleaning box, and the cleaning box has an opening that communicates with the guide plate. Multiple cleaning rods arranged side by side are rotatably connected to the cleaning box. The cleaning rods located above the cleaning box are equipped with brush bristles, and a driving component is provided at the end of the cleaning rod that passes through the guide plate.

[0018] By adopting the above technical solution, the mold is inverted above the drain plate, and the brush bristles also enter the mold. The driving component drives the cleaning rod to rotate, and the cleaning rod drives the brush bristles to wash the inside of the mold. The residue falls out of the mold, passes through the drain plate and reaches the guide plate, and then leaves the cleaning box through the opening of the guide plate.

[0019] Optionally, a cleaning rack for holding the mold is provided on one side of the cleaning tank. The cleaning rack is equipped with multiple brush rollers that surround the mold. A robotic arm for clamping and moving the mold is also provided on one side of the cleaning rack. The mold feeding conveyor belt is also provided on one side of the robotic arm. A working cover is provided at the end of the mold feeding conveyor belt near the robotic arm. An oil spray nozzle facing the mold is also provided inside the working cover. A sensor for detecting the position of the mold is also provided inside the working cover.

[0020] By adopting the above technical solution, the robotic arm will bring the cleaned mold to the cleaning frame. Multiple brush rollers surround the mold and clean the mold surface at the same time. After the mold surface is cleaned, the robotic arm moves the mold to the feeding conveyor belt. The mold enters the working hood through the mold feeding conveyor belt. The sensor detects the position of the mold, and the oil spray nozzle sprays the mold release agent into the mold. Then, it waits to enter the support frame for mold loading, thereby realizing automated mold loading.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. During the concrete filling process, the vibrating scraping mechanism vibrates the mold, thereby making the concrete evenly distributed in the mold. After the mold is filled with concrete, the conveying mechanism conveys the mold away from the hopper again. At the same time, the vibrating scraping mechanism scrapes the upper surface of the mold, thus realizing automatic concrete filling and scraping, and improving the production efficiency of concrete test blocks. 2. After demolding, the mold is cleaned by the mold cleaning mechanism, which reduces manual labor, lowers labor intensity, and improves the production efficiency of concrete test blocks.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses an automatic molding device for concrete test blocks.

[0032] Reference Figure 1 and Figure 2An automatic concrete test block loading device includes a hopper 1, a concrete feeding device connected to one side of the hopper 1, a support frame 2 below the hopper 1, multiple support rollers 21 rotatably connected to the support frame 2, a mold placed on the support rollers 21, a vibrating scraping mechanism 3 on the hopper 1, a conveying mechanism 4 for conveying the mold on the outside of the support frame 2, the conveying mechanism 4 being connected to a mold cleaning mechanism 5, a recovery pipe 22 on the support rollers 21, the recovery pipe 22 being located on the support frame 2 and below the mold, the recovery pipe 22 being used to recover the scraped concrete and convey the concrete to the concrete feeding device for reuse.

[0033] The mold moves to the bottom of the support frame 2 under the action of the conveying mechanism 4. The hopper 1 fills the mold with concrete. During the concrete filling process, the vibrating scraping mechanism 3 vibrates the mold, so that the concrete is evenly distributed in the mold. After the mold is full of concrete, the conveying mechanism 4 conveys the mold away from the hopper 1 again. At the same time, the vibrating scraping mechanism 3 scrapes the upper surface of the mold. The concrete scraped off the mold by the scraper 342 falls down and passes through the support roller 21 to the recycling pipe 22, so as to recycle the excess concrete and reuse it. This realizes the automatic filling, scraping and recycling of concrete. At the same time, the mold after demolding is cleaned by the mold cleaning mechanism 5, which improves the production efficiency of concrete test blocks.

[0034] Reference Figure 2 and Figure 3 The vibrating scraping mechanism 3 includes two vibrating rollers 31 rotatably connected to the support frame 2. The rotation axis of the vibrating rollers 31 is parallel to the support rollers 21, and the rotation axis of the vibrating rollers 31 is eccentrically set. The two rotating rollers respectively abut against the bottom of both ends of the mold. The lower end of the feeding hopper 1 is provided with an hourglass-shaped feeding port. Both sides of the middle part of the feeding port are provided with relief grooves. Rotating rods 32 are rotatably connected in the relief grooves. Multiple evenly distributed fan blades 321 are provided on the rotating rods 32. A transmission component is provided between the rotating rods 32 and the vibrating rollers 31.

[0035] When concrete falls from the hopper 1, the concrete drives the fan blade 321 and the rotating rod 32 to rotate. The rotating rod 32 drives the vibrating roller 31 to rotate through the transmission component. The vibrating roller 31 repeatedly vibrates the mold during the rotation, thereby causing the mold to shake and making the concrete inside the mold uniform.

[0036] The transmission component includes a transmission rod 33 rotatably connected to the support frame 2. One end of the transmission rod 33 is connected to the vibrating roller 31 through a gear set, and the other end is connected to the rotating rod 32 through a gear set. The support frame 2 is also equipped with a drive motor to drive the vibrating roller 31. During the rotation of the rotating rod 32, the vibrating roller 31 is driven to rotate through the gear set and the transmission rod 33. When the concrete inside the hopper 1 stops moving, or when the discharge port is blocked, the drive motor drives the vibrating roller 31 to rotate, continuing to vibrate the mold, while keeping the fan blade 321 rotating to clear the blockage of the discharge port.

[0037] Reference Figure 3 and Figure 4 A connecting rod 34, which is horizontal and vertical to the support roller 21, is rotatably connected to one side of the discharge port. A vertical baffle 341 is fixed on the connecting rod 34. An inclined scraper 342 is also provided on the side of the baffle 341 near the mold. The scraper 342 is rotatably connected to the connecting rod 34. A torsion spring is also provided between the scraper 342 and the baffle 341 to connect the two. A torsion spring is also provided between the connecting rod 34 and the discharge port to connect the two.

[0038] During the movement of the mold, it first contacts the baffle 341 and presses against the baffle 341, thereby causing the connecting rod 34 to rotate until the scraper 342 abuts against the upper surface of the mold. This adapts to molds of different heights. After the scraper 342 abuts against the upper surface of the mold, if the baffle 341 is still being pressed by the mold, the baffle 341 continues to drive the connecting rod 34 to rotate, and the scraper 342 continues to abut against the upper surface of the mold. At this time, the torsion spring is deformed by force, causing the scraper 342 and the baffle 341 to rotate relative to each other, which satisfies the normal movement of the mold. After the mold is removed from the baffle 341, the torsion spring returns to its original deformation, thereby causing the baffle 341 and the scraper 342 to return to their original positions.

[0039] The conveying mechanism 4 includes an infeed conveyor belt and an outfeed conveyor belt 42 located outside the support frame 2. An infeed hydraulic cylinder is located on the side of the infeed conveyor belt 41 away from the support roller 21. An outfeed hydraulic cylinder is also located on the side of the support frame 2 away from the outfeed conveyor belt 42. The scraper 342 is located on the side of the discharge hopper 1 near the outfeed hydraulic cylinder. The direction of the infeed hydraulic cylinder is perpendicular to the direction of the outfeed hydraulic cylinder. When the infeed conveyor belt 41 moves the empty mold to the side of the support frame 2, the infeed hydraulic cylinder pushes the empty mold to the bottom of the discharge hopper 1. After the mold is filled with concrete, the outfeed hydraulic cylinder drives the mold to leave the discharge hopper 1 and reach the outfeed conveyor belt 42, thereby completing the mold feeding and discharging work.

[0040] Reference Figure 1 , Figure 5 and Figure 6The mold cleaning mechanism 5 includes a cleaning tank 51, with a drain plate at the top of the cleaning tank 51. An inclined guide plate 52 is also provided inside the cleaning tank 51, with the lower end of the guide plate 52 extending out of the cleaning tank 51. An opening communicating with the guide plate 52 is provided on the cleaning tank 51. A recycling tank 53 is also provided on the outside of the cleaning tank 51, located below the opening. A partition 54 is also fixed inside the cleaning tank 51, located below the guide plate 52. The cavity below the partition 54 communicates with the recycling tank 53. A plurality of cleaning rods 55 are also provided on the cleaning tank 51, with one end of the cleaning rod 55 located above the cleaning tank 51 and the other end passing through the guide plate 52 and rotatably connected to the partition 54. The cleaning rods 55 located above the cleaning tank 51 are provided with bristles. A driving component for rotating the cleaning rods 55 is provided between the guide plate 52 and the partition 54.

[0041] The mold is placed upside down on top of the drain plate, and the brush bristles also enter the mold. The drive unit drives the cleaning rod 55 to rotate, and the cleaning rod 55 drives the brush bristles to clean the inside of the mold. The residue falls out of the mold, passes through the drain plate and reaches the guide plate 52, and then leaves the cleaning box 51 through the opening of the guide plate 52.

[0042] The driving component includes worm gears 56 mounted on the cleaning rod 55, all worm gears 56 meshing with the same worm 57. The cleaning tank 51 is equipped with a cleaning motor that drives the worm 57 to rotate. A water pipe 58 connected to the cleaning rod 55 is also provided below the partition 54. The cleaning rod 55 is hollow inside, and multiple water spray holes are opened at one end of the cleaning rod 55. A water pump connected to the water pipe 58 is provided below the partition 54. The area below the partition 54 and inside the recovery tank 53 is filled with cleaning fluid. A filter cloth is installed at the top of the recovery tank 53.

[0043] When the brush cleans the inside of the mold, the water pump draws the cleaning fluid and sprays it out through the water pipe 58 and the cleaning rod 55 into the spray hole, which facilitates the cleaning of the inside of the mold. The cleaning fluid and residue fall onto the guide plate 52 through the drain plate and flow out of the opening along the guide plate 52 and fall onto the filter cloth. Then the residue is blocked by the filter cloth, and the cleaning fluid re-enters the water pump for continued use.

[0044] Reference Figure 1 and Figure 7 The cleaning box 51 is also provided with a cleaning rack 59 for holding the mold on one side. Multiple brush rollers 591 are provided on the cleaning rack 59, and the brush rollers 591 surround the mold. A drive device for driving the brush rollers 591 to rotate is installed on the cleaning rack 59. A mechanical arm for clamping and moving the mold is also provided on one side of the cleaning rack 59. The mechanical arm is not shown in the figure. The mold feeding conveyor belt 41 is also provided on one side of the mechanical arm. A working cover 6 is also provided at the end of the mold feeding conveyor belt 41 near the mechanical arm. An oil spray nozzle 61 facing the mold is also provided inside the working cover 6. A sensor for detecting the position of the mold is provided inside the working cover 6.

[0045] The robotic arm brings the cleaned mold to the cleaning frame 59. Multiple brush rollers 591 surround the mold and clean its surface. After the mold surface is cleaned, the robotic arm moves the mold to the feeding conveyor belt. The mold enters the working cover 6 through the mold feeding conveyor belt 41. The sensor detects the position of the mold, and the oil spray nozzle 61 sprays the mold release agent into the mold. Then, it waits to enter the support frame 2 for mold loading, thus realizing automated mold loading.

[0046] The implementation principle of the automatic concrete test block loading device in this application embodiment is as follows: the mold moves to the support roller 21 via the mold feeding conveyor belt 41, the discharge hopper 1 feeds concrete into the mold, the vibrating scraping mechanism 3 vibrates the mold, and scrapes off the upper surface of the mold when the mold reaches the discharge conveyor belt 42. The scraped concrete is collected again through the recycling pipe 22. After the concrete test block is demolded, the mold is moved to the cleaning rack 59 to clean the surface of the mold. Then the mold is moved to the cleaning tank 51 and cleaned inside the mold. Then the robotic arm moves the mold to the mold feeding conveyor belt 41 and sprays a release agent inside the working cover 6. Then the mold reaches the discharge hopper 1 again to be filled with concrete.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
