[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0045] An embodiment of this application provides a precast concrete brick production device to solve the problems in the related art that it is difficult to accurately control the amount of concrete when the feeding hopper travels and feeds into the brick-making mold groove, the precision of material feeding is insufficient, it is difficult to achieve high-precision material rationing, it is easy to cause material waste, and at the same time, it will affect the quality of precast components, making it difficult to ensure the consistency of precast component products.

[0046] See Figures 1 to 12 As shown, an embodiment of this application provides a precast concrete brick production device, including:

[0047] A brick-making mold 2 having a first cavity 21 with an upper opening for accommodating concrete;

[0048] A fixing plate 11 provided with a through hole 111, and a side enclosure 112 extending toward the first cavity 21 is formed around the through hole 111. When the side enclosure 112 fits with the first cavity 21, a second cavity 113 is formed between the side enclosure 112 and the first cavity 21, and the volume of the second cavity 113 is equal to the volume of the first cavity 21.

[0049] In the precast concrete brick production device of the embodiment of this application, a fixing plate 11 is provided above the brick-making mold 2. When the side enclosure 112 formed around the through hole 111 on the fixing plate 11 fits with the bottom wall of the first cavity 21, a second cavity 113 is formed, and the volume of the second cavity 113 is equal to the volume of the first cavity 21. By first filling the second cavity 113 and then allowing the concrete in the second cavity 113 to flow into the first cavity 21, it is ensured that the amount of material fed into the first cavity 21 on the brick-making mold 2 matches the required amount, thereby achieving precise control of the feeding amount.

[0050] Specifically, when the feeding hopper 51 of the feeding mechanism 5 travels and feeds on the surface of the fixing plate 11, by filling the second cavity 113 and then separating the first cavity from the side enclosure, the filled concrete in the second cavity 113 will be released downward into the first cavity 21. Since the volume of the second cavity 113 is equal to the volume of the first cavity 21, the amount of concrete in the second cavity 113 can just fill the first cavity 21.

[0051] That is, by keeping the volume of the second cavity 113 consistent with the volume of the first cavity 21, it can ensure that the feeding amount into the first cavity 21 on the brick - making mold 2 matches its demand. Thus, precise control of the feeding amount can be achieved, improving the material rationing accuracy, reducing material waste, and at the same time ensuring the quality of the precast product, and guaranteeing the consistency of the precast product.

[0052] In some alternative embodiments: Refer to Figure 3 As shown, the embodiment of the present application provides a precast concrete brick production device. The horizontal cross - section of the first cavity 21 of the precast concrete brick production device is larger than the horizontal cross - section of the second cavity 113, and the depth of the first cavity 21 is less than the depth of the second cavity 113.

[0053] The horizontal cross - section of the first cavity 21 in the embodiment of the present application is larger than the horizontal cross - section of the second cavity 113, and the depth of the first cavity 21 is less than the depth of the second cavity 113. Therefore, it is convenient to use the inner cavity bottom wall of the first cavity 21 to seal the bottom opening of the side enclosure 112 to form the second cavity 113. At the same time, the hopper 51 of the feeding mechanism 5 contacts the surface of the fixed plate 11 and does not contact the brick - making mold 2, so there will be no concrete residue on the surface of the brick - making mold 2. At the same time, by filling the second cavity 113 first and then allowing the concrete in the second cavity 113 to flow into the first cavity 21, it can ensure that the feeding amount into the first cavity 21 on the brick - making mold 2 matches its demand, realizing precise control of the feeding amount.

[0054] In some alternative embodiments: Refer to Figures 1 to 4 As shown, the embodiment of the present application provides a precast concrete brick production device. The precast concrete brick production device further includes a conveying mechanism 1 for conveying the brick - making mold 2. The fixed plate 11 is fixed on the conveying mechanism 1, and a jacking mechanism 3 for jacking up the brick - making mold 2 so that the side enclosure 112 fits with the first cavity 21 is provided on the conveying mechanism 1.

[0055] The conveying mechanism 1 in the embodiment of the present application adopts a chain conveyor. The fixed plate 11 is fixed on the frame of the conveying mechanism 1. When the conveying mechanism 1 conveys the brick - making mold 2 to a suitable position below the fixed plate 11, the brick - making mold 2 can be jacked up by the jacking mechanism 3, so that the bottom wall of the first cavity 21 on the brick - making mold 2 seals the lower - end opening of the side enclosure 112 to form the second cavity 113. Then, it is convenient for the feeding mechanism 5 to feed concrete into the second cavity 113. After the second cavity 113 is filled with concrete, the brick - making mold 2 is controlled to move down by the jacking mechanism 3, and the concrete can be released into the first cavity 21 through the lower - end opening of the side enclosure 112, thereby filling the first cavity 21.

[0056] In some alternative embodiments: Refer to Figures 1 to 4As shown in the figure, an embodiment of the present application provides a precast concrete brick production device. The jacking mechanism 3 of the precast concrete brick production device includes a platform 31 disposed below the brick-making mold 2, and a first pushing member 32 for driving the platform 31 to lift and lower. The jacking end of the first pushing member 32 is connected to a cross bar 33, and an elastic support member 34 is connected between the cross bar 33 and the platform 31. A first vibration motor 35 is installed on the back of the platform 31.

[0057] In the embodiment of the present application, the first pushing member 32 is an electric push rod, which is installed on the frame cross beam of the conveying mechanism 1. By the electric push rod, the cross bar 33 can be driven to lift and lower, and then the platform 31 located above the cross bar 33 can be driven to lift and lower, so as to tightly position the brick-making mold 2 on the fixed plate 11. To ensure the support stability of the cross bar 33, guide rods slidably connected to the frame cross beam are fixed on the bottom surface of the cross bar 33 in this embodiment.

[0058] Furthermore, in this embodiment, the cross bar 33 and the platform 31 are connected by an elastic support member 34. The elastic support member 34 is a spring, which can cooperate with the first vibration motor 35 installed on the back of the platform 31. After the concrete is spread in all the first cavities 21 of the brick-making mold 2, the first vibration motor 35 can be started. The platform 31 supported by the spring drives the brick-making mold 2 to vibrate, so that the concrete after spreading is evenly spread and distributed in the first cavities 21, the voids can be eliminated, and the density of the precast concrete member can be improved.

[0059] In some alternative embodiments: Refer to Figures 1 to 5 As shown in the figure, an embodiment of the present application provides a precast concrete brick production device. A limiting mechanism 4 for blocking the front end of the brick-making mold 2 is provided on the conveying mechanism 1 of the precast concrete brick production device. The limiting mechanism 4 includes a limiting rod 41 disposed in front of the brick-making mold 2, and a second pushing member 42 for driving the limiting rod 41 to lift and lower.

[0060] The second pushing member 42 in the embodiment of the present application is also an electric push rod, which is installed on the frame cross beam of the conveying mechanism 1. By the electric push rod, the limiting rod 41 can be driven to lift and lower. When the brick-making mold 2 is not filled with concrete, the limiting rod 41 can be lifted by the electric push rod to block and limit the brick-making mold 2 below the fixed plate 11, which is convenient for the jacking mechanism 3 to lift the brick-making mold 2. To ensure the blocking stability of the limiting rod 41, guide rods slidably connected to the frame cross beam are also fixed on the bottom surface of the limiting rod 41 in this embodiment.

[0061] In some alternative embodiments: Refer to Figures 1 to 6As shown in the figure, an embodiment of the present application provides a precast concrete brick production device, which further includes a cloth feeding mechanism 5, which includes a cloth feeding hopper 51 located on the upper surface of the fixed plate 11, and a displacement assembly 52 for driving the cloth feeding hopper 51 to move so that its discharge port is docked with the through hole 111. A scraper 53 is installed at the end of the cloth feeding hopper 51, which surrounds its discharge port and is in close contact with the upper surface of the fixed plate 11.

[0062] The displacement assembly 52 of the embodiment of the present application includes a chain conveyor and a walking frame. The cloth feeding hopper 51 is fixed on the walking frame, and the walking frame is fixed on the chain of the chain conveyor. At the same time, the rollers at both ends of the walking frame are supported on the frame of the chain conveyor, so that the displacement assembly 52 can drive the cloth feeding hopper 51 to move. When the discharge port of the cloth feeding hopper 51 is aligned with the through hole 111 on the fixed plate 11, the concrete in the cloth feeding hopper 51 falls into the second cavity 113 through the through hole 111, thereby realizing the walking and cloth feeding of the cloth feeding hopper 51.

[0063] Furthermore, in this embodiment, a scraper 53 is installed at the end of the cloth feeding hopper 51, which surrounds its discharge port and is in close contact with the upper surface of the fixed plate 11. When the cloth feeding hopper 51 is walking and feeding cloth, the scraper 53 can prevent a large amount of concrete from overflowing onto the upper surface of the fixed plate 11, and at the same time, it can scrape off the excess concrete on the fixed plate 11, ensuring that the concrete just fills the second cavity 113. When the subsequent brick-making mold 2 moves down with the lifting mechanism 3 and disengages from the side enclosure 112, the concrete in the second cavity 113 is released downward into the first cavity 21, which can just fill the first cavity 21, ensuring that the feeding amount is equal to the demand of the first cavity 21, and thus reducing the waste of concrete materials.

[0064] In some alternative embodiments: Refer to Figures 1 to 8 As shown in the figure, an embodiment of the present application provides a precast concrete brick production device, which further includes a feeding mechanism 6, which includes a support frame 61, and a feeding hopper 62 installed on the support frame 61. A baffle 63 is provided at the bottom of the feeding hopper 62, and a driving member 64 for driving the baffle 63 to move to open and close the discharge port of the feeding hopper 62 is provided on the support frame 61.

[0065] The feeding hopper 62 of the embodiment of the present application has upper and lower openings and is fixedly installed on the support frame 61. A baffle 63 is attached to the bottom of the feeding hopper 62. The driving member 64 is an electric push rod and is installed on the support frame 61. The driving member 64 can drive the baffle 63 to move back and forth to realize the closing or opening of the bottom opening of the feeding hopper 62. When the bottom opening of the feeding hopper 62 is closed by the baffle 63, the feeding hopper 62 can be loaded with concrete. When the bottom opening of the feeding hopper 62 is opened by the baffle 63, the concrete in the feeding hopper 62 can fall into the cloth feeding hopper 51.

[0066] Exemplarily, in this embodiment, to ensure that the baffle 63 can bear the weight of the concrete, slideways cooperating with the baffle 63 are provided on both sides of the support frame 61. The slideways are formed by a plurality of V-groove rollers arranged at intervals and mounted on the support frame 61. A V-shaped strip cooperating with the V-groove rollers is welded to the bottom of the baffle 63.

[0067] In some alternative embodiments: Refer to Figure 7 As shown, the embodiment of the present application provides a precast concrete brick production device. A vertical frame 65 located inside the blanking hopper 62 is installed at one end of the baffle 63 of the precast concrete brick production device away from the driving member 64, and a filter screen 66 for filtering concrete is installed on the vertical frame 65.

[0068] The vertical frame 65 is fixedly installed on the baffle 63 of the embodiment of the present application. Both ends of the vertical frame 65 are slidably matched with the front and rear inner walls of the blanking hopper 62. A filter screen 66 is installed inside the vertical frame 65. The driving member 64 can drive the baffle 63 to move leftward to close the bottom opening of the blanking hopper 62. At this time, the vertical frame 65 abuts against the left inner wall of the blanking hopper 62. The concrete loaded into the blanking hopper 62 bears on the baffle 63.

[0069] When it is necessary to discharge the concrete into the distributing hopper 51, the driving member 64 drives the baffle 63 to move rightward to open the bottom opening of the blanking hopper 62. During the process of the driving member 64 driving the baffle 63 to move rightward, the baffle 63 drives the vertical frame 65 to move rightward, cooperating with the right inner wall of the blanking hopper 62, so that the filter screen 66 on the vertical frame 65 squeezes the concrete. The concrete borne on the baffle 63 passes through the filter screen 66 and then falls into the distributing hopper 51. Therefore, the purpose of intercepting large-particle sand and gravel in the concrete can be achieved, and the finished product quality of the precast member is prevented from being affected by large-particle sand and gravel in the concrete.

[0070] In some alternative embodiments: Refer to Figure 1 As shown, the embodiment of the present application provides a precast concrete brick production device. The precast concrete brick production device further includes a weighing mechanism 7, which includes a mounting frame 71 for supporting the four corners of the support frame 61, and a weighing sensor 72 installed between the mounting frame 71 and the blanking mechanism 6.

[0071] There are two mounting frames 71 in the embodiment of the present application, which are symmetrically and fixedly installed on the frame of the displacement assembly 52. Two weighing sensors 72 are installed on both mounting frames 71, which are used to connect and support the support frame 61 on the blanking mechanism 6. Furthermore, through the cooperation of the four weighing sensors 72, the weight of the concrete in the blanking hopper 62 fixed on the support frame 61 can be weighed, so as to control the weight of the concrete discharged into the distributing mechanism 5, and ensure the total amount of concrete finally discharged into the brick-making mold 2.

[0072] In some alternative embodiments: Refer to Figure 9As shown in the figure, an embodiment of the present application provides a precast concrete brick production device. On the conveying mechanism 1 of the precast concrete brick production device, there are limiting plates 12 located on both sides of the brick-making mold 2, and an adjusting component 13 for adjusting the distance between the limiting plates 12 on both sides.

[0073] In the conveying mechanism 1 of the embodiment of the present application, a chain conveyor is adopted. Limiting plates 12 are arranged on both sides of the frame of the chain conveyor. The limiting plates 12 are used for guiding and limiting the brick-making mold 2. The adjusting component 13 includes a vertical rod fixed on the frame. A fixed sleeve is fixedly connected to the vertical rod. The fixed sleeve is fixed with a horizontal rod fixedly connected to the limiting plate 12 through a set bolt. By loosening and tightening the set bolt, the horizontal rod can slide along the fixed sleeve to adjust the position of the horizontal rod, and then adjust the position of the limiting plate 12 to change the distance between the limiting plates 12 on both sides.

[0074] Exemplarily, at one end of the conveying mechanism 1 where the brick-making mold 2 is sent out in this embodiment, a conveying device is also connected and arranged. The conveying device adopts a belt conveyor 9. Limiting plates 12 and an adjusting component 13 are also installed on the belt conveyor 9. At the same time, a second vibration motor 91 is also installed on the frame of the belt conveyor 9, which can further drive the concrete in the brick-making mold 2 to vibrate during the process of conveying the brick-making mold 2, ensure that the concrete is evenly distributed in the brick-making mold 2, eliminate voids, and improve the density of the concrete precast member.

[0075] In some alternative embodiments: Refer to Figure 11 and Figure 12 As shown in the figure, an embodiment of the present application provides a precast concrete brick production device. The precast concrete brick production device further includes a feeding mechanism 8. The feeding mechanism 8 includes a feeding hopper 81 arranged above the feeding mechanism 6 and used for feeding materials into the feeding mechanism 6, and a support frame 82 for supporting the feeding hopper 81. A stirring assembly 83, a screw discharging assembly 84, and a discharging port opening and closing assembly 85 are arranged on the feeding hopper 81.

[0076] The feeding hopper 81 of the embodiment of the present application is fixedly installed on the support frame 82. The stirring assembly 83 includes a stirring rod installed in the feeding hopper 81 and a concrete for driving the stirring rod to rotate installed on the outer side wall of the feeding hopper 81, which can realize the stirring of the concrete in the feeding hopper 81.

[0077] The screw discharging assembly 84 adopts a screw pump, which can push the concrete in the feeding hopper 81 towards the side discharging port. The discharging port opening and closing assembly 85 includes a baffle hinged on the outer wall of the feeding hopper 81 and an electric push rod hinged between the baffle and the feeding hopper 81 and used for driving the baffle to close or open the side discharging port of the feeding hopper 81.
