Description

Technical Field

[0001] The invention relates to the technical field of prefabricated forming equipment, in particular to a concrete brick prefabricated forming equipment. Background Art

[0002] Precast concrete bricks are a kind of building material pre-made in the factory. They are mainly made of cement, aggregate, water, admixtures and other materials, and then made through specific mold forming and curing processes. The existing precast concrete bricks are pre-made in the factory and can be directly installed after being transported to the construction site, which greatly reduces the time of on-site construction. Compared with on-site cast concrete, precast bricks are not affected by on-site construction conditions, which greatly reduces the risk of quality problems. These advantages of precast concrete bricks make it widely needed in fields such as construction.

[0003] The prefabrication process of concrete bricks usually involves pouring the mixed concrete into a specific mold and vibrating it using equipment such as a vibrating table or vibrating rod to make the concrete dense and formed. The shape and size of the mold can be customized according to the design requirements of the prefabricated bricks. Common shapes include square, rectangular, and round. The mold is then cured and demolded to complete the production.

[0004] Existing concrete brick prefabrication molding equipment usually pours concrete into a mold, then puts the mold on a vibrating table and vibrates it to make the concrete dense and formed, and then uses a scraper to smooth the surface of the mold so that the size of the concrete is the same as the size of the mold. However, when the mold filled with concrete is vibrated and smoothed, excess concrete will fall directly onto the workbench, causing a waste of resources. For this reason, a concrete brick prefabrication molding equipment is designed. Summary of the invention

[0005] The purpose of the present invention is to provide a concrete brick prefabrication molding equipment to solve the problem that when the existing concrete brick prefabrication molding equipment vibrates and smoothes the mold filled with concrete, excess concrete will fall directly onto the workbench, causing a waste of resources.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A concrete brick prefabricated molding equipment includes a vibrating table and a mold, a suspended overflow baffle frame is installed on the top of the vibrating table, the mold is placed between the vibrating table and the overflow baffle frame, a concrete discharge channel for discharging concrete is opened on the left side of the inner wall of the overflow baffle frame, a sealing component for opening and closing the concrete discharge channel opening is installed on the surface of the overflow baffle frame, and a trowel plate that slides left and right is connected to the right side of the overflow baffle frame, and the trowel plate is used to smooth the mold surface.

[0008] Preferably, a guide plate for separating the concrete discharge channel is rotatably connected to the inner wall of the overflow baffle frame, and a baffle assembly for limiting the rotation of the guide plate is installed on the surface of the overflow baffle frame.

[0009] Preferably, a turntable is rotatably connected to the surface of the overflow baffle frame, the turntable is fixedly connected to the baffle assembly, and a transmission assembly is connected between the sealing assembly and the baffle assembly.

[0010] Preferably, a concrete pushing block is slidably connected in the groove of the concrete discharge channel, and the concrete pushing block is used to push the concrete in the concrete discharge channel to move in the direction of the opening of the concrete discharge channel, and the guide plate can move up and down.

[0011] Preferably, the left and right rear ends of the overflow baffle frame are fixedly connected with positioning baffles, and the front end of the overflow baffle frame is provided with a positioning rotating plate. The positioning rotating plate and the positioning baffle are rotatably connected, and the positioning baffle and the positioning rotating plate cooperate to limit the displacement of the mold.

[0012] Preferably, a support assembly is installed on the surface of the positioning baffle, and the support assembly is used to support the positioning rotating plate when the positioning rotating plate rotates to a horizontal state. The surface of the positioning baffle is provided with a positioning groove for the positioning rotating plate to be vertically moved and embedded.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The overflow baffle is set to prevent insufficient addition of concrete. After vibration, the liquid level of concrete in the mold cannot reach the height. By setting a trowel plate and a concrete discharge channel, after the concrete is vibrated, the excess concrete on the upper surface of the mold can be pushed to the concrete discharge channel, and the concrete on the mold surface can be smoothed. The concrete pushed to the concrete discharge channel can be discharged by opening the sealing component, which is convenient for collecting excess concrete and can prevent excess concrete from falling directly onto the workbench;

[0015] 2. By setting the guide plate and baffle assembly, the guide plate and baffle assembly can prevent concrete from entering the concrete discharge channel during the process of placing concrete and vibrating, thereby reducing the pressure at the sealing assembly, which is helpful to prevent the sealing assembly from being stretched during the process of placing concrete and vibrating;

[0016] 3. By setting the transmission assembly and the turntable, when the turntable is rotated, the baffle assembly can simultaneously release the restriction on the guide plate and the sealing assembly can open the opening of the concrete discharge channel. Conversely, the baffle assembly can simultaneously restrict the guide plate and the sealing assembly can close the opening of the concrete discharge channel, which is conducive to convenient operation.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 15 , the present invention provides a technical solution.

[0035] A concrete brick prefabrication molding device, comprising a vibration table 1 and a mold 33, a suspended overflow baffle 3 is installed on the top of the vibration table 1, the mold 33 is placed between the vibration table 1 and the overflow baffle 3, a concrete discharge channel 11 for discharging concrete is opened on the left side of the inner wall of the overflow baffle 3, a sealing component for opening and closing the opening of the concrete discharge channel 11 is installed on the surface of the overflow baffle 3, and a trowel plate 5 that slides left and right is connected to the right side of the overflow baffle 3, and the trowel plate 5 is used to smooth the surface of the mold 33;

[0036] Since the concrete is compacted during vibration, when pouring concrete into the mold 33, it is easy for the height of the concrete to be less than the height of the mold 33 after vibration. By setting the overflow baffle 3, a little more concrete can be put when prefabricating concrete bricks, as long as the concrete does not overflow the overflow baffle 3. By setting the trowel plate 5 and the concrete discharge channel 11, after the concrete is vibrated, the excess concrete on the upper surface of the mold 33 can be pushed to the concrete discharge channel 11, and the concrete on the surface of the mold 33 can be smoothed. The concrete pushed to the concrete discharge channel 11 can be discharged by opening the sealing component, which is conducive to the collection of excess concrete and can prevent the excess concrete from falling directly onto the workbench;

[0037] According to needs, a collection box can be placed below the opening of the concrete discharge channel 11 for collection, which is not shown in the drawings. Alternatively, the concrete conveying technology known to those skilled in the art can be directly adopted, and a conveying pipe can be connected to the opening of the concrete discharge channel 11 to convey the discharged concrete to a designated location in a direction.

[0038] Furthermore, the top of the vibration table 1 is fixedly connected to a suspended bracket 2, and the suspended bracket 2 is fixedly connected to the overflow baffle frame 3, so that the overflow baffle frame 3 is suspended.

[0039] Furthermore, the sealing assembly includes a second rotating shaft 21 and a sealing plate 23, the second rotating shaft 21 and the sealing plate 23 are fixedly connected, the sealing plate 23 is used to seal the opening of the concrete discharge channel 11, the second rotating shaft 21 is rotatably installed on the overflow baffle frame 3, and the sealing plate 23 is driven to rotate by rotating the second rotating shaft 21. When the sealing plate 23 rotates to seal the opening of the concrete discharge channel 11, the opening of the concrete discharge channel 11 is closed, and when the sealing plate 23 rotates away from the concrete discharge channel 11, the opening of the concrete discharge channel 11 is opened.

[0040] Furthermore, the right side of the overflow baffle frame 3 is provided with an inlay notch 4 for the trowel plate 5 to slide, the top surface of the trowel plate 5 is fixedly connected with a T-shaped slider 6, and the top wall of the inlay notch 4 is provided with a T-shaped slide groove 7 for the T-shaped slider 6 to slide.

[0041] The inner wall of the overflow baffle frame 3 is rotatably connected with a guide plate 8 for separating the concrete discharge channel 11, and the surface of the overflow baffle frame 3 is installed with a baffle assembly for limiting the rotation of the guide plate 8;

[0042] By setting the guide plate 8 and the baffle assembly, the guide plate 8 is used to separate the concrete discharge channel 11, and then the baffle assembly is used to resist the guide plate 8 to limit the rotation of the guide plate 8, so as to prevent concrete from entering the concrete discharge channel 11. In the process of pouring concrete and vibrating, by preventing concrete from entering the concrete discharge channel 11, the pressure at the sealing assembly is reduced, which is beneficial to prevent the sealing assembly from being stretched during the process of pouring concrete and vibrating. When the baffle assembly does not restrict the guide plate 8, the trowel plate 5 is used to smooth the surface of the mold 33, pushing the excess concrete to move in the direction of the concrete discharge channel 11. The concrete pressure will force the guide plate 8 to rotate, so that the concrete discharge channel 11 is connected with the inner circle of the overflow baffle frame 3.

[0043] Furthermore, the front end of the guide plate 8 is rotationally connected to the overflow baffle frame 3, and the baffle assembly is located at the rear end of the guide plate 8. The baffle assembly includes a first rotating shaft 17 and a limit baffle 22. The first rotating shaft 17 and the limit baffle 22 are fixedly connected, and the first rotating shaft 17 and the overflow baffle frame 3 are rotationally connected. The limit baffle 22 is driven to rotate by rotating the first rotating shaft 17, so that the limit baffle 22 blocks the left surface of the guide plate 8, restricting the rotation of the guide plate 8. The limit baffle 22 is rotated away from the guide plate 8, and the restriction on the guide plate 8 can be released.

[0044] Since the baffle assembly releases the restriction on the guide plate 8 when discharging concrete, and the sealing assembly is also opened when discharging concrete, the baffle assembly and the sealing assembly can be moved at the same time, which is conducive to convenient operation. The specific method is that the surface of the overflow baffle frame 3 is rotatably connected with a turntable 14, the turntable 14 is fixedly connected to the baffle assembly, and a transmission assembly is connected between the sealing assembly and the baffle assembly. By setting the transmission assembly, when the turntable 14 is rotated, the baffle assembly is driven to rotate, and the rotation of the baffle assembly drives the sealing assembly to rotate through the transmission assembly, so that the baffle assembly and the sealing assembly can be moved at the same time. At this time, only the turntable 14 needs to be rotated during the operation, which is conducive to convenient operation.

[0045] Furthermore, the first rotating shaft 17 and the turntable 14 are coaxially fixedly connected, the second rotating shaft 21 and the first rotating shaft 17 are coaxially rotationally connected, and the transmission assembly is arranged between the first rotating shaft 17 and the second rotating shaft 21. At this time, rotating the turntable 14 drives the first rotating shaft 17 to rotate, and the rotation of the first rotating shaft 17 drives the second rotating shaft 21 to rotate through the transmission assembly, so that only the turntable 14 needs to be rotated to drive the baffle assembly and the sealing assembly to rotate at the same time.

[0046] Please refer to Figure 5 , assuming that the limit baffle 22 rotates counterclockwise downward, in order to allow the limit baffle 22 to rotate, the overflow baffle frame 3 must have a gap on its surface that cannot be blocked by the sealing plate 23, and the sealing plate 23 loses its meaning of blocking. Therefore, the limit baffle 22 can only rotate clockwise upward. At this time, when the limit baffle 22 rotates clockwise, if the sealing plate 23 also rotates clockwise in the same direction as the limit baffle 22, it is necessary to rotate toward the direction of the concrete discharge channel 11, and then it is necessary to push away the concrete near the sealing plate 23 in the concrete discharge channel 11 before opening the opening of the concrete discharge channel 11, which is easy to increase the load when the turntable 14 is rotated;

[0047] For the convenience of operation, further, the sealing plate 23 and the limit baffle 22 rotate in opposite directions. Specifically, the transmission assembly includes a first bevel gear 18, a second bevel gear 19 and a third bevel gear 20. The first bevel gear 18 and the second bevel gear 19 are meshedly connected, the second bevel gear 19 and the third bevel gear 20 are meshedly connected, and the first bevel gear 18 and the third bevel gear 20 are symmetrically arranged on both sides of the second bevel gear 19. The second bevel gear 19 and the overflow baffle frame 3 are rotationally connected, the third bevel gear 20 and the second rotating shaft 21 are coaxially fixedly connected, and the first bevel gear 18 is coaxially fixedly connected to the first rotating shaft 17;

[0048] Through the transmission components, please refer to Figure 6For the convenience of explaining the rotation direction, a reference direction is assumed, that is, looking from right to left, the turntable 14 rotates clockwise, driving the first rotating shaft 17 and the limit baffle 22 to rotate clockwise, driving the first bevel gear 18 to rotate clockwise, and through the transmission of the second bevel gear 19, the third bevel gear 20 rotates counterclockwise, driving the second rotating shaft 21 and the limit baffle 22 to rotate counterclockwise, so that the limit baffle 22 and the second rotating shaft 21 rotate in opposite directions.

[0049] Furthermore, one end of the first rotating shaft 17 is coaxially fixedly connected to the third rotating shaft 24, the second rotating shaft 21 is coaxially rotatably sleeved on the surface of the third rotating shaft 24, the third rotating shaft 24 coaxially moves through the surface of the third bevel gear 20, the square block 28 is coaxially fixedly connected to the surface of the third rotating shaft 24, and the third rotating shaft 24 and the overflow baffle frame 3 are rotationally connected.

[0050] Furthermore, a hook hole 15 is provided on the surface of the turntable 14, and a hanging rope 16 used in conjunction with the hook hole 15 is installed on the back of the overflow baffle frame 3. The connection position of the hanging rope 16 and the overflow baffle frame 3 is biased to the bottom of the turntable 14, so that when the hanging rope 16 passes through the hook hole 15, please refer to Fig.15 , which will limit the upward rotation of the turntable 14, that is, it will ensure that the sealing plate 23 is in an open state, and the limit baffle 22 is in a state of releasing the restriction of the guide plate 8. When the turntable 14 rotates downward, the hanging rope 16 can be moved out from the hook hole 15.

[0051] A concrete pushing block 9 is slidably connected in the groove of the concrete discharge channel 11. The concrete pushing block 9 is used to push the concrete in the concrete discharge channel 11 to move toward the opening of the concrete discharge channel 11. When a large amount of concrete is discharged from the opening of the concrete discharge channel 11, there is still a small amount of concrete left in the concrete discharge channel 11. It cannot flow like a large amount of concrete, that is, it will stay in the concrete discharge channel 11 and not move. The residual concrete is pushed to the opening of the concrete discharge channel 11 by the concrete pushing block 9, which is helpful to prevent the residual concrete in the concrete discharge channel 11. In order to prevent the guide plate 8 from interfering with the movement of the concrete pushing block 9, the guide plate 8 can move up and down. When the concrete pushing block 9 moves, it moves upward through the guide plate 8 to the upper surface height of the concrete pushing block 9 to avoid the concrete pushing block 9.

[0052] Furthermore, the vibration table 1 includes a vibration platform and a fixed base, the vibration platform is installed on the fixed base, the top surface of the concrete pusher 9 is fixedly connected with a connecting frame 10, the surface of the fixed base of the vibration table 1 is fixedly installed with a support frame 13, the top of the support frame 13 is installed with a first electric push rod 12, the telescopic end of the first electric push rod 12 is connected to the connecting frame 10, and the connecting frame 10 is driven to move by starting the telescopic movement of the first electric push rod 12, and the movement of the connecting frame 10 drives the concrete pusher 9 to move, so that the concrete pusher 9 can push the concrete in the concrete discharge channel 11 to move in the direction of the opening of the concrete discharge channel 11.

[0053] Further, in order to reduce the setting of the control program, the guide plate 8 is pushed upward by pushing the concrete block 9 when it moves. The specific method is as follows, please refer to Fig.10 The lower corner of the front end of the guide plate 8 is an inclined corner, and the rear end of the pushing concrete block 9 is an inclined surface. When the pushing concrete block 9 moves, the inclined surface and the inclined corner contact and interact with each other, so that the guide plate 8 moves upward until it moves to the upper surface of the pushing concrete block 9 and stops. The height of the pushing concrete block 9 ensures that when the guide plate 8 moves upward, the guide plate 8 is also rotatably connected with the overflow baffle frame 3.

[0054] The left and right rear ends of the overflow baffle frame 3 are fixedly connected with positioning baffles 25. The positioning baffles 25 can be set discontinuously, and the openings of the trowel plate 5, the concrete discharge channel 11, or other additional equipment can be avoided during the setting of the positioning baffles 25. The front end of the overflow baffle frame 3 is provided with a positioning rotating plate 26, and the positioning rotating plate 26 is rotatably connected to the positioning baffle 25. The positioning baffle 25 and the positioning rotating plate 26 are used to limit the displacement of the mold 33. By setting the positioning baffle 25 and the positioning rotating plate 26, when the mold 33 is located between the overflow baffle frame 3 and the vibration table 1, the positioning baffle 25 and the positioning rotating plate 26 block the four sides of the mold 33 to limit the displacement of the mold 33, which is conducive to preventing the mold 33 from moving out of the lower end of the overflow baffle frame 3 during the vibration of the vibration table 1. Please refer to Figure 2 , through the rotational connection of the positioning rotating plate 26, an opening is provided for the mold 33 to enter and exit between the vibration table 1 and the overflow baffle frame 3.

[0055] A support assembly is installed on the surface of the positioning baffle 25, and the support assembly is used to support the positioning rotating plate 26 when the positioning rotating plate 26 rotates to a horizontal state. A positioning groove 32 is provided on the surface of the positioning baffle 25 for the positioning rotating plate 26 to move vertically and embed. The positioning rotating plate 26 is supported by the support assembly when the positioning rotating plate 26 rotates to a horizontal state, and the rotation of the positioning rotating plate 26 is restricted so that the mold 33 can be moved between the vibration table 1 and the overflow baffle frame 3. Through the positioning groove 32, when the positioning rotating plate 26 rotates to a vertical state, the positioning rotating plate 26 is moved downward and embedded, and the rotation of the positioning rotating plate 26 is restricted, so that the displacement of the mold 33 is restricted in the positioning rotating plate 26.

[0056] Furthermore, both sides of the positioning rotating plate 26 are fixedly connected with semicircular blocks 27, and the semicircular blocks 27 are eccentrically arranged, that is, the positioning rotating plate 26 has a rotating axis when rotating, and the semicircular blocks 27 are not arranged on this rotating axis. Both sides of the positioning rotating plate 26 are fixedly connected with square blocks 28, and the square blocks 28 are located between the rotating axes of the semicircular blocks 27 and the positioning rotating plate 26, and the square blocks 28 and the semicircular blocks 27 are fixedly connected. The surface of the positioning baffle 25 is provided with an annular groove 29 for the semicircular blocks 27 and the square blocks 28 to rotate. The positioning groove 32 is located at the lower end of the annular groove 29, and the positioning groove 32 is connected to the annular groove 29. When the positioning rotating plate 26 rotates, the semicircular blocks 27 and the square blocks 28 rotate in the annular groove 29. When it is in a vertical state, the semicircular blocks 27 and the square blocks 28 will move into the positioning groove 32 under the action of gravity. The rotation of the positioning rotating plate 26 is limited by the action of the square blocks 28 and the inner wall of the positioning groove 32.

[0057] Furthermore, the support assembly includes a push plate 30 and a second electric push rod 31. The positioning groove 32 allows the push plate 30 to slide up and down. The second electric push rod 31 is fixedly installed on the surface of the fixed base of the vibration table 1. The telescopic end of the second electric push rod 31 is located below the push plate 30. By starting the second electric push rod 31 to extend, the push plate 30 can be supported to move upward.

[0058] Please refer to Fig.12 When the semicircular block 27 and the square block 28 are located in the positioning groove 32, the push plate 30 is moved upward to lift the semicircular block 27, the square block 28 and the positioning rotating plate 26 upward until the square block 28 and the semicircular block 27 move into the annular groove 29. At this time, the mold 33 moves outward to push the positioning rotating plate 26 to rotate until the positioning rotating plate 26 rotates and is horizontally attached to the top surface of the mold 33. The length of the square block 28 is greater than the diameter of the inner ring of the annular groove 29, and the length of the push plate 30 is equal to the diameter of the inner ring of the annular groove 29. Please refer to Fig.13 When the positioning rotating plate 26 is in a horizontal state, the push plate 30 is pushed against the inner circle of the annular groove 29 by moving upward. Since the length of the square block 28 is greater than the diameter of the inner ring of the annular groove 29, part of the surface of the square block 28 will be in contact with the push plate 30. When the push plate 30 does not move, it will support the positioning rotating plate 26 and limit the positioning rotating plate 26 from rotating downward.

[0059] As set up as above, since when the vibration table 1 vibrates, it is usually when the mold 33 is located between the vibration table 1 and the overflow baffle frame 3, the positioning turn plate 26 needs to be in a vertical state. At this time, the output end of the second electric push rod 31 can be away from the push plate 30, so that the positioning turn plate 26 cannot directly transmit the vibration to the second electric push rod 31, which is helpful to prevent the second electric push rod 31 from being indirectly or directly connected to the positioning turn plate 26 all the time, frequently being in a vibrating state, and reducing the service life.

[0060] The specific scheme is as follows: the positioning rotating plate 26 is first in a horizontal state, and then the mold 33 is moved between the vibration table 1 and the overflow baffle frame 3, and then the second electric push rod 31 is started to shrink, so that the push plate 30 moves down, the positioning rotating plate 26 loses support and flips downward, so that the semicircular block 27 and the square block 28 move along the track of the annular groove 29, and finally, they are embedded in the positioning groove 32 for fixing, and then the vibration table 1 is started to vibrate the vibration platform, and concrete is poured into the mold 33 from above the overflow baffle frame 3, and the concrete is vibrated and compacted, and then the vibration table 1 can be closed, and the first rotating shaft 17 and the limit baffle 22 are rotated upward by rotating the turntable 14, and the third rotating shaft 24, the first bevel gear 18, the second bevel gear 19, and the third bevel gear 20 are rotated. The transmission causes the second rotating shaft 21 and the sealing plate 23 to rotate downward, opening the opening of the concrete discharge channel 11, and releasing the limit on the guide plate 8, and hooking the hanging rope 16 through the hook hole 15 to fix the turntable 14, and by pushing the trowel plate 5 to smooth the upper surface of the mold 33, and pushing the concrete on the upper surface of the mold 33 to the concrete discharge channel 11, the guide plate 8 rotates under pressure, so that the excess concrete moves into the concrete discharge channel 11, and is guided by the guide plate 8 to flow and be discharged from the opening of the concrete discharge channel 11, and then the first electric push rod 12 is started to extend, pushing the connecting frame 10 and the concrete pushing block 9 to move, and pushing the remaining concrete in the concrete discharge channel 11 to the opening of the concrete discharge channel 11 again. When the concrete pushing block 9 contacts the guide plate 8 during the movement, it will push the guide plate 8 to move upward.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
