[0008] The working principle of the present application is that when the concrete lock block is used for slope protection to prevent water and soil loss, the concrete lock blocks are assembled, the T blocks are embedded in the T grooves of the adjacent concrete lock blocks, the superposition blocks are pressed on the superposition grooves, and the arc water channels of the front and rear adjacent concrete lock blocks are connected.

[0009] After the concrete lock block is installed, the slope protection plants are planted in the rectangular grass planting holes to protect the water and soil. When it rains, the wedge water collecting channels collect water and deliver the water to the arc water channels, the rainwater quickly passes through the arc water channels, the water is discharged, the soil layer expansion caused by rainwater infiltration is reduced, the slope deformation is inhibited, and the protection ability is enhanced.

[0010] A preparation method of an environmental protection type concrete lock block, the preparation method steps are as follows:

[0011] Step one, construction waste enters the field; after the construction waste is collected, it is transported into the factory, and is stored and sorted in the factory yard;

[0012] Step two, multi-stage crushing and impurity removal; the qualified raw materials are subjected to multi-stage crushing, and the slag, light impurities and metals in the construction waste are removed at each stage of crushing;

[0013] Step three, batching and stirring; the obtained recycled aggregate, fly ash, cement and water are proportioned according to weight parts, and the weight parts of each component are: cement 310 parts, water 165 parts, sand 589 parts, fly ash 80 parts and recycled aggregate 1044 parts, and are sequentially fed into a mixer for mixing and stirring to obtain an environmental protection concrete;

[0014] Step four, forming; the obtained environmental protection concrete is placed into a forming equipment, and a semi-finished lock block is vibrated and pressed in a forming mold, and the lock block mold and the semi-finished lock block therein are conveyed out;

[0015] Step five, steam curing; the mold and the semi-finished lock block therein are fed into a curing kiln for steam curing.

[0016] The environmentally friendly concrete molding equipment used in step four includes conveyor two, a vibration mechanism, a quantitative dispensing mechanism, conveyor one, a transport and output mechanism, a pressing mechanism, an adsorption and transport mechanism, several upper locking blocks and several lower locking blocks. The upper end of the vibration mechanism is equipped with an electric rotary table, on which several groups of circumferentially distributed blocking mechanisms are provided. Two blocking mechanisms in each group are symmetrically arranged on the electric rotary table. The quantitative dispensing mechanism, conveyor one, transport and output mechanism, pressing mechanism and adsorption and transport mechanism are arranged around the vibration mechanism in sequence, and the positions of the quantitative dispensing mechanism, conveyor one, transport and output mechanism, pressing mechanism and adsorption and transport mechanism are circumferentially distributed. Conveyor two is located below the adsorption and transport mechanism. Several upper locking blocks are arranged sequentially on conveyor two, and several lower locking blocks are arranged sequentially on conveyor one. The adsorption and transport mechanism is connected to an external vacuum pump through a pipeline.

[0017] Using the above structure, conveyor one transports a locking block lower mold to the electric rotary table, where it is limited by a set of blocking mechanisms. Then, the electric rotary table drives the locking block lower mold to move below the quantitative dispensing mechanism. The electric rotary table then stops moving. At this time, a new locking block lower mold is transported to the electric rotary table by conveyor one and is limited by another set of blocking mechanisms. Then, the workers place the environmentally friendly concrete into the quantitative dispensing mechanism, which quantitatively dispenses the environmentally friendly concrete into the locking block lower mold. The vibration mechanism vibrates intermittently to flatten the environmentally friendly concrete that falls into the locking block lower mold, reducing the gaps in the environmentally friendly concrete.

[0018] The electric rotary table continues to move, driving the lower mold of the locking block to move below the adsorption and conveying mechanism. The electric rotary table stops moving. At this time, a new lower mold of the locking block moves to below the quantitative dispensing mechanism. The above operation is repeated. The adsorption and conveying mechanism adsorbs an upper mold of the locking block on the second conveyor and transports the upper mold of the locking block to the upper mold of the locking block. The upper mold of the locking block is then placed on the lower mold of the locking block.

[0019] The electric rotary table continues to move, driving the lower and upper molds of the locking block to move below the pressing mechanism. The electric rotary table then stops moving. At this time, a new lower mold of the locking block moves to below the suction and conveying mechanism. The above operation is repeated. The pressing mechanism moves against the upper mold of the locking block and, in conjunction with the vibration mechanism, vibrates and presses the environmentally friendly concrete between the lower and upper molds of the locking block, so that it completely fills the mold cavity formed between the lower and upper molds of the locking block and locks the upper mold of the locking block. The upper mold of the locking block is then locked onto the lower mold of the locking block.

[0020] The electric rotary table continues to move, driving the locking block mold formed by the lower and upper locking blocks to the position of the transport output mechanism. At this time, a new lower locking block mold moves to the bottom of the pressing mechanism. The above operation is repeated. The transport output mechanism moves, driving the locking block mold to break through the limit of a set of blocking mechanisms and moves the locking block mold onto the transport output mechanism. The locking block mold is then transported out.

[0021] The electric rotary table continues to move to the position of conveyor one, and the above operation is repeated. At this time, a new locking block lower mold moves to the position of the transport output mechanism, and the above operation is repeated.

[0022] The vibration mechanism includes a vibration frame and a vibration plate. The vibration plate is located directly above the vibration frame. Vibration springs are provided between the four corners of the lower end of the vibration plate and the four corners of the upper end of the vibration frame. A vibration motor is fixed at the middle position of the lower end of the vibration plate.

[0023] With the above structure, the vibration motor drives the vibration plate to vibrate intermittently at the upper end of the four vibration springs.

[0024] The electric rotary table is located at the middle of the upper part of the vibrating plate. The upper part of the electric rotary table is provided with a rotating plate, and the rotating plate is provided with five support plates circumferentially distributed. Each support plate extends out of the rotating plate and is provided with a U-shaped limiting plate located on the side of the support plate. Each support plate has two symmetrically arranged blocking and limiting holes on the front side of the upper end.

[0025] With the above structure, the electric rotary table rotates intermittently, driving the rotating plate to rotate. The rotation of the rotating plate drives the five support plates to rotate at the same time. The blocking and limiting holes facilitate the movement of the blocking mechanism, and the limiting plates are used to limit the lower mold of the locking block.

[0026] The blocking mechanism includes a U-shaped mounting plate and a blocking limit block. The blocking limit block is slidably disposed in the blocking limit hole. The upper end of the U-shaped mounting plate is fixed to the front side of the lower end of the support plate. The U-shaped mounting plate is provided with two hinge seats. A return spring is hinged between the blocking limit block and the two hinge seats.

[0027] With the above structure, when the lower die of the locking block passes by, the lower die of the locking block squeezes the blocking limit block, and the blocking limit block slides in the blocking limit hole. At the same time, the blocking limit block squeezes two return springs. After the lower die of the locking block passes by, the two return springs act and drive the blocking limit block back to the initial position. The blocking limit block cooperates with the U-shaped mounting plate to limit the lower die of the locking block.

[0028] The quantitative dispensing mechanism includes a dispensing frame, a dispensing hopper fixed inside the dispensing frame, two vibrating motors at the lower ends of both sides of the dispensing hopper, a dispensing pipe at the lower end of the dispensing hopper connected to the dispensing hopper, a discharge ramp at one end of the dispensing pipe, an electric push rod at the other end of the dispensing pipe, a pusher plate at the telescopic end of the electric push rod, the size and shape of the pusher plate matching the dispensing pipe, a blocking plate at the upper end of the pusher plate, connecting plates at both sides of the pusher plate, and a blocking plate at the ends of the two connecting plates. The blocking plate, the blocking plate, and the two connecting plates are all located inside the dispensing pipe. The size and shape of the blocking plate match the dispensing pipe. A blocking port is opened at the other end of the dispensing pipe, and the other end of the pusher plate is slidably disposed inside the blocking port.

[0029] Using the above structure, in the initial state, the first blocking plate blocks the connection between the distribution pipe and the distribution hopper, and the second blocking plate blocks the connection between the distribution pipe and the discharge slope. The worker places the environmentally friendly concrete into the distribution hopper, and then the two vibrating motors move. At the same time, the telescopic end of the electric push rod drives the push plate and the first blocking plate to move. The first blocking plate no longer blocks the connection between the distribution pipe and the distribution hopper. The environmentally friendly concrete falls into the distribution pipe under the action of the two vibrating motors. After the distribution pipe is filled, the telescopic end of the electric push rod drives the push plate to move. The push plate pushes the environmentally friendly concrete in the distribution pipe to move. During the movement, the second blocking plate no longer blocks the connection between the distribution pipe and the discharge slope. Then the push plate pushes the environmentally friendly concrete into the discharge slope, and the environmentally friendly concrete is transported out from the discharge slope.

[0030] The adsorption and transport mechanism includes a transport frame, on which is provided an electric lead screw. A mounting seat is provided on the lead screw slide of the electric lead screw, and an electric push rod is fixed on the mounting seat. A suction cup fixing plate is fixed on the telescopic end of the electric push rod. An air extraction pipe is provided inside the suction cup fixing plate, and the air extraction pipe is connected to an external vacuum pump through a pipe. Several suction cups are provided below the suction cup fixing plate, and each suction cup is connected to the air extraction pipe through a pipe.

[0031] Using the above structure, the first electric lead screw drives the first lead screw slide to move, the first lead screw slide drives the mounting base to move, and the mounting base drives the second electric push rod and the suction cup fixing plate to move to above a locking block upper mold on the second conveyor. The telescopic end of the second electric push rod drives the suction cup fixing plate and several suction cups to move downward. Several suction cups abut against the locking block upper mold. Then, the external vacuum pump sucks the air between several suction cups and the locking block upper mold through the air extraction pipe. Several suction cups adhere to the locking block upper mold, and then move upward under the drive of the telescopic end of the second electric push rod. Under the drive of the first electric lead screw, it is transported to the top of the electric rotary table, and then moves downward again under the drive of the telescopic end of the second electric push rod. Then, the external vacuum pump stops working, the locking block upper mold is placed on the locking block lower mold, and then returns to the initial position.

[0032] The pressing mechanism includes an electric lifting screw assembly. The screw slide of the electric lifting screw assembly is provided with a lifting seat. An electric push rod is fixed below the lifting seat. A pressure plate is fixed below the telescopic end of the electric push rod. The size of the pressure plate matches that of the upper mold of the locking block.

[0033] Using the above structure, the electric lifting screw drives the screw slide three to move, the screw slide three drives the lifting seat to move, the lifting seat drives the electric push rod three and the pressure plate to move, the telescopic end of the electric push rod three drives the pressure plate to move, so that the pressure plate abuts against the upper mold of the locking block, squeezes the upper mold of the locking block, and cooperates with the vibration mechanism to flatten the environmentally friendly concrete between the upper mold of the locking block and the lower mold of the locking block, so that the environmentally friendly concrete fills the mold cavity and is continuously pressed, so that the upper mold of the locking block is locked onto the lower mold of the locking block.

[0034] The conveying and output mechanism includes a conveyor three, a support plate two on the conveyor three, and electric lead screw components two symmetrically arranged on both sides of the upper end of the conveyor three. A connecting plate is provided between the lead screw slides two of the two electric lead screw components two. An electric push rod four is fixed at the middle position of the upper end of the connecting plate. A push plate is fixed below the telescopic end of the electric push rod four.

[0035] With the above structure, when the locking block mold is output, the two electric lead screws move synchronously, driving the connecting plate and the electric push rod four on it to move to the top of the locking block mold. The telescopic end of the electric push rod four drives the push plate to move. The push plate is inserted between the limit plate and the locking block mold. Then, the two electric lead screws move synchronously, driving the push plate to move and pushing the locking block mold to move, so that the locking block mold breaks through the limit and moves to the conveyor three. The locking block mold is then conveyed out by the conveyor three.

[0036] The upper mold of the locking block includes an upper mold body, and the lower ends of the four sides of the upper mold body are provided with engagement grooves. The lower end of the upper mold body is provided with a punch, and the shape and size of the punch match the upper end of the concrete locking block.

[0037] The locking block lower mold includes a lower mold body, inside which is a concave mold that matches the shape and size of the lower end of the concrete locking block. The upper end of the lower mold body has two locking pin units on each of its four sides. Each locking pin unit includes a guide limit seat, on which are provided two symmetrically arranged sliding tubes. Locking pins slide inside the two sliding tubes. The ends of the locking pins are frustoconical and match the shape and size of the locking grooves. The locking pins are provided with a stop bar and a locking spring, both of which are located between the two sliding tubes.

[0038] With the above structure, when the upper die of the locking block is engaged with the lower die of the locking block, the upper die body presses the engaging pin to slide within the two sliding tubes. After the upper die body descends to the moving position, the end of the engaging pin is aligned with the engaging groove. At this time, the engaging pin returns to its initial position under the action of the engaging spring and engages within the engaging groove, thus serving as a limiting device.

[0039] The cavity formed by the punch and die matches the shape and size of the concrete locking block, and the stop bar is used to limit the movement of the locking pin.

[0040] Compared with existing technologies, this environmentally friendly concrete interlocking block and its preparation method have the following advantages:

[0041] This environmentally friendly concrete locking block is easy to assemble and install, has a fast drainage speed, and strong protective capabilities.

[0042] The environmentally friendly concrete molding equipment used in the preparation method of this invention can achieve stable and automated production of concrete blocks through automatic input, limited intermittent vibration, quantitative material distribution, stable adsorption and transportation, pressing and molding, and stable output.

[0043] This preparation method is highly automated, produces good molding results, and has stable quality.

[0044] The lower mold of the locking block is conveyed onto the electric rotary table via a conveyor, enabling automatic input.

[0045] The electric rotary table, in conjunction with the blocking mechanism, limits the lower mold of the locking block, facilitating subsequent processing. It also works with the vibration mechanism to perform intermittent vibration, reducing gaps and ensuring quality.

[0046] The quantitative dispensing mechanism works in conjunction with the electric rotary table to perform quantitative dispensing, ensuring stable quality.

[0047] The adsorption and conveying mechanism works in conjunction with the electric rotary table to accurately and stably adsorb and convey the locking block onto the upper mold, facilitating mold closing.

[0048] The pressing mechanism works in conjunction with the electric rotary table to press and vibrate the molding process, and to close the upper mold and lower mold of the locking block, thus ensuring structural strength.

[0049] The locking block mold is pushed out of the electric rotary table by the conveying and output mechanism, breaking through the limit of the electric rotary table and stabilizing the output. Attached Figure Description

[0068] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0069] like Figures 1-3 As shown, this environmentally friendly concrete locking block includes a locking block body 1. A rectangular planting hole 3 is provided at the upper end of the locking block body 1. An arc-shaped water passage 5 and a wedge-shaped water collection channel 6 are provided at the upper end of the locking block body 1. The wedge-shaped water collection channel 6 and the arc-shaped water passage 5 are connected and perpendicular to each other. The wedge-shaped water collection channel 6 and the arc-shaped water passage 5 are respectively located on the side of the rectangular planting hole 3. A superimposed groove 4 is provided on one side of the upper end of the locking block body 1. The superimposed groove 4 is perpendicular to the wedge-shaped water collection channel 6. A superimposed block 7 is provided on the other side of the upper end of the locking block body 1. The shape and size of the superimposed block 7 match the superimposed groove 4. T-shaped blocks 2 are provided on the lower ends of two adjacent sides of the locking block body 1. T-shaped grooves 8 are provided on the lower ends of the other two adjacent sides of the locking block body 1. The shape and size of the T-shaped blocks 2 match the T-shaped grooves 8.

[0070] When concrete lock blocks are used for slope protection to prevent soil erosion, the concrete lock blocks are assembled, with T-shaped blocks 2 fitting into the T-shaped grooves 8 of adjacent concrete lock blocks, and overlapping blocks 7 covering the overlapping grooves 4, and the arc-shaped water passages 5 of adjacent concrete lock blocks connected.

[0071] After the concrete locking blocks are installed, slope protection plants are planted in the rectangular planting holes 3 to protect the soil and water. When it rains, the wedge-shaped water collection channel 6 collects water and transports it to the arc-shaped water passage 5. The rainwater passes quickly through the arc-shaped water passage 5 and is discharged, reducing the soil expansion caused by rainwater infiltration, thereby inhibiting slope deformation and enhancing protection capabilities.

[0072] This environmentally friendly concrete locking block is easy to assemble and install, has a fast drainage speed, and strong protective capabilities.

[0073] like Figures 4-16 As shown, the preparation method of this environmentally friendly concrete interlocking block includes the following steps:

[0074] Step 1: Construction waste enters the site; after being collected, the construction waste is transported into the plant and stored and sorted in the plant's storage yard.

[0075] Step 2, multi-stage crushing and impurity removal; qualified raw materials undergo multi-stage crushing, and during each stage of crushing, slag, light impurities and metals in the construction waste are removed.

[0076] Step 3, batching and mixing: The obtained recycled aggregate, fly ash, cement and water are batched according to the following weight proportions: 310 parts cement, 165 parts water, 589 parts sand, 80 parts fly ash and 1044 parts recycled aggregate. The mixture is then fed into a mixer for mixing to obtain environmentally friendly concrete.

[0077] Step 4, molding; The obtained environmentally friendly concrete is placed into the molding equipment, vibrated and pressed into semi-finished locking blocks in the molding mold, and the locking block mold and the semi-finished locking blocks inside are conveyed out.

[0078] Step 5, steam curing; send the mold and the semi-finished locking blocks inside into the curing kiln for steam curing.

[0079] The environmentally friendly concrete molding equipment used in step four includes a second conveyor 17, a vibration mechanism 9, a quantitative dispensing mechanism 18, a first conveyor 10, a transport output mechanism 13, a pressing mechanism 14, an adsorption transport mechanism 15, several upper locking blocks 16, and several lower locking blocks 19. The upper end of the vibration mechanism 9 is equipped with an electric rotary table 12, which is equipped with several groups of circumferentially distributed blocking mechanisms 11. Two blocking mechanisms 11 in each group are symmetrically arranged on the electric rotary table 12. The quantitative dispensing mechanism 18, the first conveyor 10, the transport output mechanism 13, the pressing mechanism 14, and the adsorption transport mechanism 15 are arranged around the vibration mechanism 9 in sequence, and the positions of the quantitative dispensing mechanism 18, the first conveyor 10, the transport output mechanism 13, the pressing mechanism 14, and the adsorption transport mechanism 15 are circumferentially distributed. The second conveyor 17 is located below the adsorption transport mechanism 15. Several upper locking blocks 16 are arranged sequentially on the second conveyor 17, and several lower locking blocks 19 are arranged sequentially on the first conveyor 10. The adsorption transport mechanism 15 is connected to an external vacuum pump through a pipeline.

[0080] Conveyor 10 transports a locking block lower mold 19 to the electric rotary table 12, where it is limited by a set of blocking mechanisms 11. The electric rotary table 12 then moves the locking block lower mold 19 to below the quantitative dispensing mechanism 18. The electric rotary table 12 then stops moving. At this time, a new locking block lower mold 19 is transported to the electric rotary table 12 by conveyor 10 and limited by another set of blocking mechanisms 11. Then, the worker places the environmentally friendly concrete into the quantitative dispensing mechanism 18, which quantitatively dispenses the environmentally friendly concrete into the locking block lower mold 19. The vibration mechanism 9 vibrates intermittently to flatten the environmentally friendly concrete that falls into the locking block lower mold 19, reducing the gaps in the environmentally friendly concrete.

[0081] The electric rotary table 12 continues to move, driving the lower mold 19 of the locking block to move below the adsorption and conveying mechanism 15. The electric rotary table 12 stops moving. At this time, a new lower mold 19 of the locking block moves to below the quantitative dispensing mechanism 18. The above operation is repeated. The adsorption and conveying mechanism 15 adsorbs an upper mold 16 of the locking block on the second conveyor 17, and transports the upper mold 16 of the locking block to the upper mold 19 of the locking block, and places the upper mold 16 of the locking block on the lower mold 19 of the locking block.

[0082] The electric rotary table 12 continues to move, driving the lower mold 19 and the upper mold 16 of the locking block to move below the pressing mechanism 14. The electric rotary table 12 stops moving. At this time, a new lower mold 19 of the locking block moves to the lower suction and conveying mechanism 15. The above operation is repeated. The pressing mechanism 14 moves to abut against the upper mold 16 of the locking block, and cooperates with the vibration mechanism 9 to vibrate and press the environmentally friendly concrete between the lower mold 19 and the upper mold 16 of the locking block, so that it completely fills the mold cavity formed between the lower mold 19 and the upper mold 16 of the locking block, and makes the upper mold 16 of the locking block lock onto the lower mold 19 of the locking block.

[0083] The electric rotary table 12 continues to move, driving the locking block mold formed by the lower locking block mold 19 and the upper locking block mold 16 to the position of the transport output mechanism 13. At this time, a new lower locking block mold 19 moves to the bottom of the pressing mechanism 14. The above operation is repeated. The transport output mechanism 13 moves, driving the locking block mold to break through the limit of a set of blocking mechanisms 11 and move the locking block mold onto the transport output mechanism 13. The locking block mold is then transported out.

[0084] The electric rotary table 12 continues to move to the position of the conveyor 10 and repeats the above operation. At this time, a new locking block lower mold 19 moves to the position of the transport output mechanism 13 and repeats the above operation.

[0085] The vibration mechanism 9 includes a vibration frame 22 and a vibration plate 20. The vibration plate 20 is located directly above the vibration frame 22. Vibration springs 21 are provided between the four corners of the lower end of the vibration plate 20 and the four corners of the upper end of the vibration frame 22. A vibration motor is fixed at the middle position of the lower end of the vibration plate 20.

[0086] The vibration motor drives the vibration plate 20 to vibrate intermittently at the upper ends of the four vibration springs 21.

[0087] The electric rotary table 12 is located at the middle of the upper end of the vibrating plate 20. The upper end of the electric rotary table 12 is provided with a rotating plate 25. Five support plates 26 are evenly distributed in a circle on the rotating plate 25. The support plates 26 extend out of the rotating plate 25. Each support plate 26 is provided with a U-shaped limiting plate 24. The limiting plate 24 is located on the side of the support plate 26. Two symmetrically arranged blocking and limiting holes 23 are opened on the front side of the upper end of each support plate 26.

[0088] The electric rotary table 12 rotates intermittently, driving the rotating plate 25 to rotate. The rotation of the rotating plate 25 drives the five support plates 26 to rotate. The blocking limit hole 23 facilitates the movement of the blocking mechanism 11. The limit plate 24 is used to limit the lower mold 19 of the locking block.

[0089] The blocking mechanism 11 includes a U-shaped mounting plate 30 and a blocking limit block 29. The blocking limit block 29 is slidably disposed in the blocking limit hole 23. The upper end of the U-shaped mounting plate 30 is fixed to the front side of the lower end of the support plate 26. Two hinge seats 28 are provided on the U-shaped mounting plate 30. A return spring 27 is hinged between the blocking limit block 29 and the two hinge seats 28.

[0090] When the lower die 19 of the locking block passes through, the lower die 19 of the locking block presses against the blocking limit block 29. The blocking limit block 29 slides within the blocking limit hole 23. At the same time, the blocking limit block 29 presses against the two return springs 27. After the lower die 19 of the locking block passes through, the two return springs 27 act and drive the blocking limit block 29 back to its initial position. The blocking limit block 29 cooperates with the U-shaped mounting plate 30 to limit the lower die 19 of the locking block.

[0091] The quantitative dispensing mechanism 18 includes a dispensing frame 38, within which a dispensing hopper 31 is fixed. Vibration motors 37 are installed at the lower ends of both sides of the dispensing hopper 31. A dispensing pipe 35 is installed at the lower end of the dispensing hopper 31, connecting to the dispensing hopper 31. A discharge ramp 36 is provided at one end of the dispensing pipe 35, and an electric push rod 33 is fixed at the other end of the dispensing pipe 35. A push plate 32 is fixed to the telescopic end of the electric push rod 33. The size and shape of the pusher plate 32 are matched with the distribution pipe 35. A blocking plate 1 is fixed at the upper end of the pusher plate 32. A connecting plate is fixed on both sides of the pusher plate 32. A blocking plate 2 is fixed at the end of the two connecting plates. The blocking plate 2, the blocking plate 1 and the two connecting plates are all located inside the distribution pipe 35. The size and shape of the blocking plate 2 are matched with the distribution pipe 35. A blocking port 34 is opened at the other end of the distribution pipe 35. The other end of the pusher plate 32 is slidably set in the blocking port 34.

[0092] Initially, the first blocking plate blocks the connection between the distribution pipe 35 and the distribution hopper 31, and the second blocking plate blocks the connection between the distribution pipe 35 and the discharge ramp 36. The worker places the environmentally friendly concrete into the distribution hopper 31. Then, the two vibrating motors 37 move, and at the same time, the telescopic end of the electric push rod 33 drives the push plate 32 and the first blocking plate to move. The first blocking plate no longer blocks the connection between the distribution pipe 35 and the distribution hopper 31. Under the action of the two vibrating motors 37, the environmentally friendly concrete falls into the distribution pipe 35. After the distribution pipe 35 is filled, the telescopic end of the electric push rod 33 drives the push plate 32 to move. The push plate 32 pushes the environmentally friendly concrete in the distribution pipe 35. During the movement, the second blocking plate no longer blocks the connection between the distribution pipe 35 and the discharge ramp 36. Then, the push plate 32 pushes the environmentally friendly concrete into the discharge ramp 36, and the environmentally friendly concrete is conveyed out from the discharge ramp 36.

[0093] The adsorption and handling mechanism 15 includes a handling frame 45, on which an electric lead screw 39 is provided. The lead screw slide of the electric lead screw 39 is provided with a mounting base 43. An electric push rod 42 is fixed on the mounting base 43. A suction cup fixing plate 40 is fixed on the telescopic end of the electric push rod 42. An air extraction pipe 44 is provided inside the suction cup fixing plate 40. The air extraction pipe 44 is connected to an external vacuum pump through a pipe. Several suction cups 41 are provided below the suction cup fixing plate 40. The several suction cups 41 are all connected to the air extraction pipe 44 through pipes.

[0094] Electric lead screw 39 drives lead screw slide 1 to move, lead screw slide 1 drives mounting base 43 to move, mounting base 43 drives electric push rod 42 and suction cup fixing plate 40 to move to above a locking block upper mold 16 on conveyor 17. The telescopic end of electric push rod 42 drives suction cup fixing plate 40 and several suction cups 41 to move downward. Several suction cups 41 abut against the locking block upper mold 16. Then, the external vacuum pump sucks the air between several suction cups 41 and locking block upper mold 16 through the air extraction pipe 44. Several suction cups 41 adsorb the locking block upper mold 16, and then move upward under the drive of the telescopic end of electric push rod 42. Under the drive of electric lead screw 39, it is transported to above electric rotary table 12, and then moves downward again under the drive of the telescopic end of electric push rod 42. Then, the external vacuum pump stops working, and the locking block upper mold 16 is placed on the locking block lower mold 19, and then returns to the initial position.

[0095] The pressing mechanism 14 includes an electric lifting screw 46. The screw slide of the electric lifting screw 46 is provided with a lifting seat 49. An electric push rod 48 is fixed below the lifting seat 49. A pressure plate 47 is fixed below the telescopic end of the electric push rod 48. The size of the pressure plate 47 matches that of the upper mold of the locking block.

[0096] The electric lifting screw 46 drives the screw slide three to move, the screw slide three drives the lifting seat 49 to move, the lifting seat 49 drives the electric push rod three 48 and the pressure plate 47 to move, the telescopic end of the electric push rod three 48 drives the pressure plate 47 to move, so that the pressure plate 47 abuts against the upper mold 16 of the locking block, squeezes the upper mold 16 of the locking block, and cooperates with the vibration mechanism 9 to flatten the environmentally friendly concrete between the upper mold 16 of the locking block and the lower mold 19 of the locking block, so that the environmentally friendly concrete fills the mold cavity and continues to press, so that the upper mold 16 of the locking block is locked onto the lower mold 19 of the locking block.

[0097] The conveying output mechanism 13 includes a conveyor 3 50, a support plate 2 54 on the conveyor 3 50, and symmetrically arranged electric lead screw components 2 55 on both sides of the upper end of the conveyor 3 50. A connecting plate 53 is provided between the lead screw slides of the two electric lead screw components 2 55. An electric push rod 4 52 is fixed at the middle position of the upper end of the connecting plate 53. A push plate 51 is fixed below the telescopic end of the electric push rod 4 52.

[0098] When the locking block mold is output, the two electric lead screws 55 move synchronously, driving the connecting plate 53 and the electric push rod 52 on it to move to the top of the locking block mold. The telescopic end of the electric push rod 52 drives the push plate 51 to move. The push plate 51 is inserted between the limiting plate 24 and the locking block mold. Then, the two electric lead screws 55 move synchronously, driving the push plate 51 to move, pushing the locking block mold to move, so that the locking block mold breaks through the limit and moves to the conveyor 50. The locking block mold is then conveyed out by the conveyor 50.

[0099] The upper mold 16 of the locking block includes an upper mold body 58. The lower ends of the upper mold body 58 are provided with engagement grooves 57. The lower end of the upper mold body 58 is provided with a punch 56. The punch 56 matches the shape and size of the upper end of the concrete locking block.

[0100] The lower mold 19 of the locking block includes a lower mold body 59. The lower mold body 59 has a cavity mold 61 inside. The cavity mold 61 matches the shape and size of the lower end of the concrete locking block. The upper end of the lower mold body 59 has two locking pin units 60 on each of its four sides. The locking pin unit 60 includes a guide limit seat 63. The guide limit seat 63 has two symmetrically arranged sliding tubes 62. The locking pins 64 are slidably arranged in the two sliding tubes 62. The ends of the locking pins 64 are frustoconical and match the shape and size of the locking groove 57. The locking pins 64 are equipped with a stop bar 65 and a locking spring 66. The stop bar 65 and the locking spring 66 are both located between the two sliding tubes 62.

[0101] When the upper die 16 of the locking block engages with the lower die 19 of the locking block, the upper die body 58 presses the locking pin 64 to slide within the two sliding tubes 62. After the upper die body 58 descends to the moving position, the end of the locking pin 64 is aligned with the locking groove 57. At this time, the locking pin 64 returns to its initial position under the action of the locking spring 66 and engages within the locking groove 57, thus serving as a limiting device.

[0102] The cavity formed by the punch 56 and the die 61 matches the shape and size of the concrete locking block, and the stop bar 65 is used to limit the movement of the locking pin 64.

[0103] Example 1

[0104] An environmentally friendly concrete interlocking block is made from the following raw materials in parts by weight: 310 parts cement, 165 parts water, 589 parts sand, 80 parts fly ash and 1044 parts recycled aggregate.

[0105] Construction waste enters the site; after being collected, the construction waste is transported into the plant and stored and sorted in the plant's storage yard.

[0106] Multi-stage crushing and impurity removal: qualified raw materials are crushed in multiple stages, and slag, light impurities and metals in construction waste are removed during each crushing stage;

[0107] Ingredient mixing: The obtained recycled aggregate, fly ash, cement and water are proportioned and fed into a mixer in sequence for mixing to obtain environmentally friendly concrete.

[0108] Forming: Conveyor 10 transports a locking block lower mold 19 to the electric rotary table 12, where it is limited by a set of blocking mechanisms 11. As the locking block lower mold 19 passes, it presses against the blocking limiting block 29, which slides within the blocking limiting hole 23. Simultaneously, the blocking limiting block 29 presses against two return springs 27. After the locking block lower mold 19 passes, the two return springs 27 act and drive the blocking limiting block 29 back to its initial position. The blocking limiting block 29, in conjunction with the U-shaped mounting plate 30, limits the locking block lower mold 19. Subsequently, the electric rotary table 12 moves the locking block lower mold 19 to below the quantitative dispensing mechanism 18, where the electric rotary table 12 pauses. At this point, a new locking block lower mold 19 is transported to the electric rotary table 12 by conveyor 10 and limited by another set of blocking mechanisms 11. Then, the worker places environmentally friendly concrete into the quantitative dispensing mechanism 18. The environmentally friendly concrete is quantitatively delivered into the lower mold 19 of the locking block. That is, the worker places the environmentally friendly concrete into the distribution hopper 31. Then, the two vibrating motors 37 move, and at the same time, the telescopic end of the electric push rod 33 drives the push plate 32 and the blocking plate 1 to move. The blocking plate 1 no longer blocks the connection between the distribution pipe 35 and the distribution hopper 31. The environmentally friendly concrete falls into the distribution pipe 35 under the action of the two vibrating motors 37. After the distribution pipe 35 is filled, the telescopic end of the electric push rod 33 drives the push plate 32 to move. The push plate 32 pushes the environmentally friendly concrete in the distribution pipe 35 to move. During the movement, the blocking plate 2 no longer blocks the connection between the distribution pipe 35 and the discharge slope 36. Then, the push plate 32 pushes the environmentally friendly concrete into the discharge slope 36. The environmentally friendly concrete is delivered out from the discharge slope 36. The vibrating mechanism 9 vibrates intermittently, that is, the vibrating motor drives the vibrating plate 20 to vibrate intermittently, which vibrates and flattens the environmentally friendly concrete that falls into the lower mold 19 of the locking block, reducing the gaps in the environmentally friendly concrete.

[0109] The electric rotary table 12 continues to move, causing the lower mold 19 of the locking block to move below the adsorption and conveying mechanism 15. The electric rotary table 12 then stops moving. At this time, a new lower mold 19 of the locking block moves below the quantitative dispensing mechanism 18. The above operation is repeated. The adsorption and conveying mechanism 15 adsorbs an upper mold 16 of the locking block on the second conveyor 17 and moves the upper mold 16 of the locking block above the lower mold 19 of the locking block. The upper mold 16 of the locking block is then placed on the lower mold 19 of the locking block. That is, the electric lead screw 39 drives the lead screw slide 1 to move, the lead screw slide 1 drives the mounting base 43 to move, and the mounting base 43 drives the electric push rod 42 and the suction cup fixing plate 40 to move to a locking block on the second conveyor 17. Above the upper mold 16, the telescopic end of the electric push rod 42 drives the suction cup fixing plate 40 and several suction cups 41 to move downward. Several suction cups 41 abut against the upper mold 16 of the locking block. Then, the external vacuum pump sucks the air between several suction cups 41 and the upper mold 16 of the locking block through the air extraction pipe 44. Several suction cups 41 adsorb the upper mold 16 of the locking block. Then, driven by the telescopic end of the electric push rod 42, it moves upward and is transported to the top of the electric rotary table 12 by the electric lead screw 39. Then, driven by the telescopic end of the electric push rod 42, it moves downward again. Then, the external vacuum pump stops working and places the upper mold 16 of the locking block on the lower mold 19 of the locking block. Then, it returns to the initial position.

[0110] The electric rotary table 12 continues to move, driving the lower mold 19 and upper mold 16 of the locking block to move below the pressing mechanism 14. The electric rotary table 12 then pauses its movement. At this time, a new lower mold 19 of the locking block moves to below the suction and conveying mechanism 15. The above operation is repeated. The pressing mechanism 14 moves and abuts against the upper mold 16 of the locking block, and works in conjunction with the vibration mechanism 9 to vibrate and press the environmentally friendly concrete between the lower mold 19 and the upper mold 16 of the locking block, so that it completely fills the mold cavity formed between the lower mold 19 and the upper mold 16 of the locking block, and makes the upper mold 16 of the locking block engage with the lower mold 19 of the locking block. That is, the electric lifting screw 46 drives the screw slide three to move, and the screw slide three drives the lifting seat 49 to move. The lifting seat 49 drives the electric push rod 3 48 and the pressure plate 47 to move. The telescopic end of the electric push rod 3 48 drives the pressure plate 47 to move, so that the pressure plate 47 abuts against the upper mold 16 of the locking block, squeezing the upper mold 16 of the locking block, and cooperating with the vibration mechanism 9 to flatten the environmentally friendly concrete between the upper mold 16 of the locking block and the lower mold 19 of the locking block, so that the environmentally friendly concrete fills the mold cavity and continues to press. The upper mold body 58 squeezes the locking pin 64 to slide in the two sliding tubes 62. After the upper mold body 58 descends to the moving position, the end of the locking pin 64 is directly facing the locking groove 57. At this time, the locking pin 64 returns to the initial position under the action of the locking spring 66 and locks in the locking groove 57, which plays a limiting role.

[0111] The electric rotary table 12 continues to move, driving the locking block mold formed by the lower locking block mold 19 and the upper locking block mold 16 to the position of the transport output mechanism 13. At this time, a new lower locking block mold 19 moves to the lower part of the pressing mechanism 14. The above operation is repeated. The transport output mechanism 13 moves, driving the locking block mold to break through the limit of a set of blocking mechanisms 11 and move the locking block mold onto the transport output mechanism 13. The locking block mold is conveyed out. That is, the two electric screw components 55 move synchronously, driving the connecting plate 53 and the electric push rod 52 on it to move to the upper part of the locking block mold. The telescopic end of the electric push rod 52 drives the push plate 51 to move. The push plate 51 is inserted between the limit plate 24 and the locking block mold. Then the two electric screw components 55 move synchronously, driving the push plate 51 to move, pushing the locking block mold to move, so that the locking block mold breaks through the limit and moves onto the conveyor 50. The locking block mold is conveyed out by the conveyor 50.

[0112] The electric rotary table 12 continues to move to the position of the conveyor 10 and repeats the above operation. At this time, a new locking block lower mold 19 moves to the position of the transport output mechanism 13 and repeats the above operation.

[0113] Steam curing: The mold and the semi-finished locking blocks inside it are sent into the curing kiln for steam curing.

[0150] Performance testing

[0151] To better illustrate the present invention, the performance of the recycled building waste bricks obtained in each embodiment is tested below. The permeability and compressive strength of the products are tested using industry standard testing methods, and comparisons are made with comparative examples.

[0152] The specific test method for water conduction time is as follows:

[0153] (1) Randomly select a sufficient number of concrete lock blocks;

[0154] (2) The selected concrete lock blocks are assembled and placed on the slope to form a specimen slope protection. Then, a certain amount of water is sprayed from the upper side of the specimen slope protection to simulate rainy weather and test the drainage time of the concrete lock block specimen.

[0155] The specific test method for compressive strength is as follows:

[0156] (1) Randomly select a sufficient number of concrete lock blocks;

[0157] (2) Place the prepared concrete lock block specimen stably under the pressure testing machine, apply pressure slowly, and record the pressure value when the concrete lock block specimen fails.

[0158] The results of water conduction time and compressive strength tests in the examples and comparative examples are as follows: Figure 17 As shown.

[0159] The comparison of the compressive strength test results of Comparative Example 1 and Examples 1-9 above shows that the concrete interlocking blocks made with the mix proportion used in Example 1 have better compressive strength and more stable structural strength.

[0160] A comparison of the water conduction time test results between Example 1 and Comparative Example 2 shows that the concrete locking block used in Example 1 has a shorter water conduction time and a faster drainage speed.

[0161] The environmentally friendly concrete molding equipment used in the preparation method of this invention can achieve stable and automated production of concrete blocks through automatic input, limited intermittent vibration, quantitative material distribution, stable adsorption and transportation, pressing and molding, and stable output.

[0162] In summary, by cooperating with the electric rotary table 12, the lower mold 19 of the locking block is conveyed to the electric rotary table 12, thus realizing automatic input;

[0163] The electric rotary table 12, in conjunction with the blocking mechanism 11, limits the lower mold 19 of the locking block, facilitating subsequent processing. It also works with the vibration mechanism 9 to perform intermittent vibration, reducing gaps and ensuring quality.

[0164] The quantitative dispensing mechanism 18 works in conjunction with the electric rotary table 12 to perform quantitative dispensing, ensuring stable quality.

[0165] The adsorption and transport mechanism 15 works in conjunction with the electric rotary table 12 to accurately and stably adsorb and transport the upper mold 16 of the locking block, which facilitates mold closing.

[0166] The pressing mechanism 14 works in conjunction with the electric rotary table 12 to press and vibrate the molding process, and to close the upper mold 16 and the lower mold 19 of the locking block to ensure structural strength.

[0167] The locking block mold is pushed out of the electric rotary table 12 by the conveying output mechanism 13 and the electric rotary table 12, breaking through the limit of the electric rotary table 12 and stabilizing the output.
