Technical Field
[0001] This utility model relates to the field of precast component production technology, specifically to precast component material laying equipment and precast component production line. Background Technology
[0002] Fabric placement equipment is crucial for the mass production of precast components. While there are many types of existing automated fabric placement equipment, they all have some drawbacks. For example, some existing equipment struggles to achieve precise fabric placement, severely impacting the quality and yield of precast products; they also suffer from complex structures, difficult cleaning, poor reliability, and complex maintenance. Therefore, for fabric placement equipment capable of automated production, higher requirements are placed on the structural design and performance of precast component fabric placement equipment.
[0003] In some application areas, the use of small precast components is relatively large, and improving the production efficiency and product quality of these components places high demands on precast component placement equipment. Therefore, the applicant proposes a precast component placement equipment and production line that can at least partially solve the aforementioned problems. Utility Model Content
[0004] The purpose of this application is at least to provide a new type of precast component laying equipment and precast component production line with advantages such as simple structure, easy cleaning and maintenance, high reliability, and meeting the needs of automated production. This is specifically achieved through the following solution:
[0005] Firstly, the precast component feeding device provided in this application includes a hopper, a base, a first cutting-off assembly, and a second cutting-off assembly. The base is installed below the hopper, and a hopper is provided on the base. The inlet of the hopper is located directly below the outlet of the hopper, and the hopper is a cavity extending vertically downward from the inlet of the hopper. The first cutting-off assembly is installed on the base and is configured to isolate and connect the inlet of the hopper and the outlet of the hopper. The second cutting-off assembly is installed on the base and is configured to block and open the outlet of the hopper.
[0006] This application, by installing the base below the hopper and making the hopper on the base a vertically downward extending cavity, allows concrete to smoothly enter the hopper from the hopper under gravity. This arrangement also facilitates internal cleaning of the concrete placing equipment after use. Furthermore, by enabling the first cutting component to isolate and connect the hopper's inlet and the hopper's outlet, and the second cutting component to block and open the hopper's outlet, the application achieves the concrete placing function through control of the first and second cutting components. This enables precise concrete placing, effectively improving the quality of concrete placement and better meeting the needs of automated and intelligent concrete placing.
[0007] In some embodiments of this application, the first interruption assembly includes a first partition plate and a first push-pull assembly. The first partition plate is slidably connected to a base, and the first push-pull assembly is mounted on the base. The push-pull end of the first push-pull assembly is connected to the first partition plate. The first push-pull assembly is configured to allow the first partition plate to have a position that separates the feed inlet of the hopper from the discharge outlet of the hopper, and a position that connects the feed inlet of the hopper to the discharge outlet of the hopper. The second interruption assembly includes a second partition plate and a second push-pull assembly. The second partition plate is slidably connected to the base, and the second push-pull assembly is mounted on the base. The push-pull end of the second push-pull assembly is connected to the second partition plate. The second push-pull assembly is configured to allow the second partition plate to have a position that blocks the discharge outlet of the hopper and a position that opens the discharge outlet of the hopper.
[0008] This application enables the precast component placement equipment to place materials by pushing and pulling the first and second push-pull components. The precast component placement equipment of this application not only has a simple structure, but also has the advantages of being easy to implement and having good reliability.
[0009] In some embodiments of this application, a hopper is provided on the base, the inlet of the hopper is located directly below the outlet of the hopper, and a first disconnection component is provided on one side of the inlet of the hopper, which enables the inlet of the hopper and the outlet of the hopper to be in a disconnected state and a connected state; a second disconnection component is provided on one side of the outlet of the hopper, which enables the outlet of the hopper to be in a blocked state and an open state.
[0010] In some embodiments of this application, the base may optionally be provided with multiple partitioned hoppers, the inlet of each hopper being located directly below the outlet of the hopper, and each hopper inlet being provided with a first disconnecting component that enables the hopper inlet and the hopper outlet to be in a disconnected state and a connected state; and each hopper outlet being provided with a second disconnecting component that enables the hopper outlet to be in a blocked state and an open state.
[0011] This application, by incorporating multiple partitioned hoppers on a base, with each hopper equipped with a first and a second disconnecting assembly, allows for independent control of each hopper. This enables the precast component feeding equipment to simultaneously or partially feed material onto the molds with precision, effectively improving precast component production efficiency and enhancing the equipment's flexibility and applicability. Furthermore, by arranging multiple feeding units, including hoppers, on the base, this application also allows for simultaneous feeding onto multiple molds, better meeting the needs of mass production of small precast components and possessing significant potential for widespread application.
[0012] In some embodiments of this application, the base is provided with a through-channel adapted to the first partition plate. The through-channel is connected to the hopper. The first partition plate is configured to extend into the hopper through the through-channel to separate the hopper's inlet from the outlet of the hopper.
[0013] In some embodiments of this application, slides are provided on both sides of the discharge port of the hopper, and the opposite sides of the second partition plate are respectively corresponding to and slidably adapted to the slides. The second push-pull assembly is installed on the base, and the pushing and pulling direction of the second push-pull assembly is parallel to the extension direction of the slide.
[0014] In some embodiments of this application, the inner wall of the hopper is further provided with a protruding rib extending a predetermined length toward the first cutting component. The protruding rib is located near the running trajectory of the first partition plate. When the first partition plate is positioned to separate the feed inlet of the hopper from the discharge outlet of the hopper, at least a portion of the protruding rib is located below the first partition plate.
[0015] This application provides a protruding rib extending a predetermined length toward the first cutting component on the inner wall of the hopper, and positions the protruding rib near the running trajectory of the first partition plate. When the first partition plate is positioned to separate the inlet of the hopper from the outlet of the hopper, the first partition plate and the protruding rib are vertically misaligned, thereby better isolating the hopper and the hopper. This effectively prevents concrete from entering the hopper when material is discharged, thus achieving more precise material distribution.
[0016] In some embodiments of this application, the precast component feeding device further includes a guide hopper, which is connected to the base, and a guide hopper is provided below the discharge port of each hopper. The guide hopper includes a gradually narrowing guide channel from top to bottom.

A discharge hopper is provided below the discharge port of each guide hopper, and at least some of the discharge hoppers are rotatable to adjust the position of the discharge port of the discharge hopper.
[0018] This application includes a guide hopper and a discharge hopper in the precast concrete placing equipment, thereby guiding the concrete falling from the hopper to the mold more effectively. Furthermore, by incorporating a rotatable discharge hopper, the position of the discharge hopper can be adjusted according to production needs, thus enhancing the versatility of the precast concrete placing equipment.

[0020] This application includes a volume adjustment module in the precast component, which allows for adjustment of the hopper's volume, thereby adjusting the single-discharge amount of the precast component feeding equipment to better meet the adjustment needs of different precast component production. Specifically, the volume adjustment structure extends from the receiving cavity into the hopper to adjust the hopper's volume.
[0021] In some embodiments of this application, the volume adjustment module further includes a third push-pull assembly, which is mounted on a base and has its push-pull end facing the hopper and connected to the volume adjustment structure. The third push-pull assembly is configured to drive the volume adjustment structure into the hopper.
[0022] This application includes a third push-pull component in the volume adjustment module, thereby allowing the position of the volume adjustment structure to be adjusted by controlling the third push-pull component to meet the position adjustment needs of the volume adjustment module.
[0023] In some embodiments of this application, the hopper is a square channel extending vertically downwards, the receiving cavity is a square cavity extending horizontally and connected to the square channel, and the volume adjustment structure is a structure adapted to the square cavity and is square in shape overall.
[0024] In some embodiments of this application, the first interruption component, the second interruption component, and the volume adjustment module are all located on the same side of the base.

[0055] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0056] The following is based on Figures 1 to 7 This invention introduces the precast component fabrication equipment and precast component production line provided by this utility model.
[0057] The precast component feeding device provided in this application includes a hopper 1, a base 2, a first cutting component 3, and a second cutting component 4. The base 2 is installed below the hopper 1, and a hopper 21 is provided on the base 2. The inlet of the hopper 21 is located directly below the outlet of the hopper 1. The hopper is a cavity extending vertically downward from the inlet of the hopper 21. The first cutting component 3 is installed on the base 2 and is configured to both isolate and connect the inlet of the hopper 21 and the outlet of the hopper 1. The second cutting component 4 is configured to both block and open the outlet of the hopper 21. In actual operation, feeding is achieved by controlling only the first cutting component 3 and the second cutting component 4.
[0058] This application, by installing the base 2 below the hopper 1 and making the hopper 21 on the base 2 a vertically downward extending cavity, allows concrete to smoothly enter the hopper 21 from the hopper 1 under the action of gravity. This arrangement also facilitates the internal cleaning of the concrete placing equipment after use. In addition, by enabling the first cutting component 3 to isolate and connect the inlet of the hopper 21 and the outlet of the hopper 1, and enabling the second cutting component 4 to block and open the outlet of the hopper 21, the application can achieve the concrete placing function by controlling the first cutting component 3 and the second cutting component 4. Moreover, it can achieve precise concrete placing, effectively improve the quality of concrete placing, and better meet the needs of automated and intelligent concrete placing.
[0059] It should be noted that the term "hopper" in this application is not specifically limited; it can be any funnel-shaped container capable of holding concrete. It is a common component of concrete placing equipment, and its specific structure will not be elaborated upon. The specific shape and size can be selectively set according to actual needs. To facilitate concrete placing and make the placing more uniform, a mixing device 8 is further provided on the hopper 1 (specifically as shown in...). Figure 6 As shown). Specifically as follows: Figure 4 and Figure 6 As shown, the mixing device 8 is a mixing device that includes a drive motor and a mixing assembly. In actual operation, the drive motor is controlled to drive the mixing assembly to mix the concrete.
[0060] Furthermore, the term "base" in this application is not specifically limited; it can be any structure that has a hopper 21 and meets the installation requirements of the first breaking component 3 and the second breaking component 4. Specifically, as follows... Figures 1 to 7 As shown, the base 2 is a structure made of sheet metal. In specific implementations, the base 2 can be selectively made into a single structure, or it can be made into multiple structural units connected by connectors (such as bolt and nut assemblies).
[0061] It should be noted that the "first disconnection component" in this application is not specifically limited, and it can be any component that enables the feed inlet of the hopper 21 and the discharge outlet of the hopper 1 to switch between a disconnected state and a connected state.
[0062] In a specific implementation, this application makes the first interruption component 3 include a first partition plate 31 and a first push-pull component 32. The first partition plate 31 is slidably connected to the base 2, and the first push-pull component 32 is mounted on the base 2. The push-pull end of the first push-pull component 32 is connected to the first partition plate 31. The first push-pull component 32 is configured to enable the first partition plate 31 to have a position that separates the inlet of the hopper 21 from the outlet of the hopper 1 (not shown in the figure) and a position that connects the inlet of the hopper 21 with the outlet of the hopper 1 (e.g., ...). Figure 4.1 (The location shown).
[0063] Specifically, such as Figure 1 , Figure 1.1 , Figure 4 , Figure 4.1 and Figure 5 As shown, the first disconnecting assembly 3 includes a hydraulic cylinder and a first partition plate 31. The hydraulic cylinder is horizontally mounted on the base 2, and its telescopic end faces the side where the hopper 21 is located and is hinged to the first partition plate 31. In actual operation, the position of the first partition plate 31 is adjusted by extending and retracting the hydraulic cylinder, so that the feed inlet of the hopper 21 and the discharge outlet of the hopper 1 are either in a disconnected state or in a connected state.
[0064] In practical operation, when the first partition plate 31 is positioned to separate the inlet of the hopper 21 from the outlet of the hopper 1, the first partition plate 31 can prevent concrete in the hopper from entering the hopper 21. When the first partition plate 31 is positioned to connect the inlet of the hopper 21 with the outlet of the hopper 1, concrete in the hopper 1 can flow into the hopper.
[0065] Similarly, it should be noted that the "second disconnecting component" in this application is not specifically limited, and it can be any component that can switch the discharge port of the hopper 21 between a blocked state and an open state.
[0066] In a specific implementation, the second interruption assembly 4 includes a second partition plate 41 and a second push-pull assembly 42. The second partition plate 41 is slidably connected to the base 2, and the second push-pull assembly 42 is mounted on the base 2. The push-pull end of the second push-pull assembly 42 is connected to the second partition plate 41, and the second push-pull assembly 42 is configured to allow the second partition plate 41 to have a position where it is in the position of blocking the outlet of the hopper 21 (not shown in the figure) and a position where it is in the position of opening the outlet of the hopper 21 (e.g., ...). Figure 4.1 (As shown).
[0067] For example, Figure 1 , Figure 1.1 , Figure 4 , Figure 4.1 and Figure 5 As shown, the second disconnecting assembly 4 includes a hydraulic cylinder and a second partition plate 41. The hydraulic cylinder is horizontally mounted on the lower part of the base 2, and its telescopic end faces the side where the hopper 21 is located and is hinged to the second partition plate 41. In actual operation, the position of the second partition plate 41 is adjusted by the telescopic movement of the hydraulic cylinder, so that the outlet of the hopper 21 is either blocked or open.
[0068] The "first push-pull assembly" in this application is not specifically limited and can be any assembly capable of pushing and pulling the first partition plate. In specific implementations, the first push-pull assembly 32 can be selectively chosen as any one of a hydraulic cylinder, a gear and rack linear transmission module, a lead screw and slider linear transmission module, and an electric cylinder.
[0069] It should be noted that the first push-pull component 32 in this application is not limited to the components listed above. Any existing push-pull component that can push and pull the first partition plate 31 so that the feed inlet of the hopper 21 and the discharge outlet of the hopper 1 can switch between a partitioned state and a connected state is within the protection scope of this application.
[0070] The "second push-pull assembly" in this application is not specifically limited; it can be any assembly capable of pushing and pulling the second partition plate 41. In specific implementations, the second push-pull assembly 42 can be selectively chosen from any one of a hydraulic cylinder, a gear and rack linear transmission module, a lead screw and slider linear transmission module, and an electric cylinder. It should also be noted that the second push-pull assembly 42 in this application is not limited to the components listed above; it can be any existing push-pull assembly capable of pushing and pulling the second partition plate 41 so that the discharge port of the hopper 21 can switch between a blocked state and an open state, and all such assemblies are within the scope of protection of this application.
[0071] This application provides a novel precast component placing device comprising a first cutting component 3, a second cutting component 4, and a base 2. The base 2 is equipped with a hopper 21, and the first cutting component 3 can adjust the connection between the hopper 21 and the material bin 1. The second cutting component 4 can block or open the hopper 21. Thus, the precast component placing device can perform its placing function by controlling the first cutting component 3 and the second cutting component 4. This application provides a novel precast component placing device that differs from existing placing devices and has advantages such as simple structure and high reliability.
[0072] In addition, the precast concrete placement equipment provided in this application, under the action of the first cutting component 3 and the second cutting component 4, enables the hopper 21 to provide an equal amount of concrete to the mold each time, thereby achieving accurate metering and placement of precast components, and better meeting the needs of automated operation of the placement device.
[0073] As some preferred embodiments of this application, the base 2 may selectively be provided with a plurality of partitioned hoppers 21. As some alternative embodiments of this application, the number of hoppers 21 provided on the base 2 may be 2, 3, 4, 5, 6, 7, or 8. Specifically, as follows... Figure 6 and Figure 7 As shown, there are three hoppers 21 on the base 2, and the three hoppers are spaced apart within the base 2 along a direction perpendicular to the push-pull direction of the first push-pull assembly. It should also be noted that the number of hoppers 21 on the base 2 is not limited to the number listed above, and can be selectively set as needed.
[0074] In the embodiment including multiple partitioned hoppers 21, the inlet of each hopper 21 is located directly below the outlet of the hopper 1. Each hopper 21 has a first disconnecting component 3 at its inlet, which enables the inlet of the hopper 21 and the outlet of the hopper 1 to be in a disconnected state and a connected state; each hopper 21 has a second disconnecting component 4 at its outlet, which enables the outlet of the hopper 21 to be in a blocked state and an open state.
[0075] Specifically, such as Figure 1 , Figure 1.1 , Figure 2 , Figure 2.1 , Figure 3 , Figure 6 and Figure 7 As shown, the multiple hoppers 21 set on the base 2 are all located directly below the discharge port of the hopper 1, and each hopper 21 is equipped with a first cutting component 3 and a second cutting component 4, thereby forming multiple units that can realize material distribution.
[0076] This application, by providing multiple partitioned hoppers 21 on the base 2, with each hopper 21 equipped with a first disconnecting component 3 and a second disconnecting component 4, allows each hopper 21 to be individually controlled. This enables the precast component feeding equipment to simultaneously or partially feed material onto multiple molds with precision, effectively improving the production efficiency of precast components. Furthermore, it enhances the flexibility and applicability of the precast component feeding equipment, making it particularly suitable for feeding small precast components.
[0077] As a preferred embodiment of the foregoing implementation, the cavity of each hopper 21 extends vertically downwards directly below the discharge port of the hopper 1. This application ensures that the cavity of each hopper 21 extends vertically downwards directly below the discharge port of the hopper 1, thereby enabling material to fall under the influence of gravity and effectively simplifying the structure of the precast component placement equipment. Furthermore, by positioning the hopper 21 directly below the discharge port of the hopper 1, cleaning and maintenance of the precast component placement equipment are facilitated after the placement process, effectively reducing the failure rate of the placement device.
[0078] As some embodiments of this application, a hopper 21 may optionally be provided on the base 2, with the inlet of the hopper 21 located directly below the outlet of the hopper 1. A first disconnecting component 3 is provided on one side of the inlet of the hopper 21, enabling the inlet of the hopper 21 and the outlet of the hopper 1 to be in a state of separation or connection. A second disconnecting component 4 is provided on one side of the outlet of the hopper 21, enabling the outlet of the hopper 21 to be in a state of blockage or open. Specifically... Figure 1 The multiple hoppers in the hopper are changed into one hopper, that is, a hopper 21 is set directly below the discharge port of hopper 1.
[0079] As some preferred embodiments of the foregoing implementation, the base 2 is provided with a through-channel 22 adapted to the first partition plate 31. The through-channel 22 is connected to the hopper 21, and the first partition plate 31 is configured to extend into the hopper 21 through the through-channel 22 to separate the feed inlet of the hopper 21 from the discharge outlet of the hopper 1. Specifically, as follows... Figure 1.1 and Figure 4.1 As shown, a through-channel 22 adapted to the end face of the first partition plate 31 is formed on the side wall of the base 2. The first partition plate 31 is adapted to the through-channel 22, and the upper surface of the first partition plate 31 is hinged to the push-pull end of the first push-pull assembly 32 via a hinged support. In actual operation, by controlling the first push-pull assembly 32, the first partition plate 31 extends into the hopper 21 through the through-channel 22 to isolate the feed inlet of the hopper 21 from the discharge outlet of the hopper 1, or to keep the feed inlet of the hopper 21 and the discharge outlet of the hopper 1 connected.
[0080] In some preferred embodiments of this application, slides 23 are provided on both sides of the discharge port of the hopper 21. The opposite sides of the second partition plate 41 correspond one-to-one with and are slidably connected to the slides 23. The second push-pull assembly 42 is mounted on the base 2, and the pushing / pull direction of the second push-pull assembly 42 is parallel to the extending direction of the slides 23. Specifically, Figure 2.1 and Figure 4.1As shown, each hopper 21 has a base 2 on both sides of the discharge port with a slide rail 23 extending along the pushing and pulling direction of the second push-pull assembly 42. The second partition plate 41 is horizontally arranged and its two opposite sidewalls are slidably adapted to the slide rail 23; and the pushing and pulling end of the second push-pull assembly 42 is hinged to the second partition plate 41. In actual operation, by controlling the second push-pull assembly 42, the second partition plate 41 slides along the slide rail 23 to adjust the position of the second partition plate 41 relative to the discharge port of the hopper 21, so as to block or open the hopper 21.
[0081] As some preferred embodiments of this application, the inner wall of the hopper 21 may be further selectively provided with a protruding rib 24 extending a predetermined length toward the first cutting assembly 3. The protruding rib 24 is positioned near the running trajectory of the first partition plate 31, directly below it. When the first partition plate 31 is positioned to separate the inlet of the hopper 21 from the outlet of the hopper 1, at least a portion of the protruding rib 24 is located below the first partition plate 31. Specifically, as follows... Figure 4.1 As shown, a rib 24 extending towards the side of the hopper 21 away from the first partition plate 31 is provided, and the rib 24 extends horizontally along the direction of movement perpendicular to the first partition plate 31, and the rib 24 is a plate with a certain thickness. When the first partition plate 31 is positioned to separate the feed inlet of the hopper 21 from the discharge outlet of the hopper 1, the rib 24 is located near the gap between the first partition plate 31 and the inner wall of the hopper 21, so as to better separate the discharge outlet of the hopper 1 from the hopper 21.
[0082] This application provides a protruding rib 24 extending a predetermined length toward the first cutting component 3 on the inner wall of the hopper 21, and positions the protruding rib 24 near the running trajectory of the first partition plate 31. When the first partition plate 31 is positioned to separate the inlet of the hopper 21 from the outlet of the hopper 1, the first partition plate 31 and the protruding rib 24 are vertically misaligned, achieving a labyrinth seal effect. This better isolates the hopper 1 and the hopper 21, effectively preventing concrete from entering the hopper 21 when material is being discharged, thus achieving more precise material distribution.
[0083] To achieve better material placement, the precast component material placement equipment also includes a guide hopper 5. The guide hopper 5 is connected to the base 2, and a guide hopper 5 is correspondingly set below the discharge port of each hopper 21. The guide hopper 5 includes a gradually narrowing guide channel from top to bottom.
[0084] As some preferred embodiments of the foregoing implementation, the precast component feeding device further includes a guide hopper 5 and a discharge hopper 6. The guide hopper 5 is connected to the base 2, and a guide hopper 5 is correspondingly arranged below the discharge port of each hopper 21. The guide hopper 5 includes a gradually narrowing guide channel from top to bottom, and a discharge hopper 6 is respectively provided below the discharge port of each guide hopper 5. At least some of the discharge hoppers 6 are rotatably configured to adjust the position of the discharge port of the discharge hopper 6 as needed. Specifically, as follows... Figure 2 , Figure 2.1 , Figure 3 and Figure 7 As shown, three parallel shafts are installed at the lower part of the base 2, and each shaft is rotatably connected to a discharge hopper 6 corresponding to the guide hopper 5; and the discharge hoppers 6 on both sides can rotate relative to the shafts to adjust the position of the discharge port of the guide hopper 5.
[0085] The structure of the feed hopper in this application is not specifically limited; it can be any structure that meets the feed guiding requirements. Specifically, as shown below... Figure 6 The feed hopper 5 shown is funnel-shaped.
[0086] This application includes a precast concrete placing device with a guide hopper 5 and a discharge hopper 6, which allows for better guidance of the concrete falling from the hopper 21 into the mold. Furthermore, by providing a rotatable discharge hopper 6, the position of the discharge hopper 6 can be adjusted according to production needs, thus improving the versatility of the precast concrete placing device.
[0087] As some preferred embodiments of this application, the precast component feeding device may also include a volume adjustment module 7. The volume adjustment module 7 includes a volume adjustment structure 71. The base 2 is provided with receiving cavities 25 that correspond one-to-one with and communicate with the hoppers 21. The receiving cavities 25 are located on one side of the hoppers 21, and the volume adjustment structure 71 is slidably adapted to and connected to the receiving cavities 25. The volume adjustment structure 71 is configured to extend from the receiving cavities 25 into the hoppers 21 to adjust the volume of the inner cavity of the hoppers 21.
[0088] It should be noted that the volume adjustment module 7 in this application is a component, unit, or system for adjusting the volume of the hopper 21. The structure of the volume adjustment structure 71 included in the volume adjustment module 7 in this application is not specifically limited; it can be any structure that is adapted to the receiving cavity 25 and can enter the hopper 21 from the receiving cavity 25.
[0089] Specifically, such as Figure 4 and Figure 4.1As shown, the hopper 21 is a vertically extending square channel within the base 2. Three square receiving cavities 25 are provided on the base 2. Each receiving cavity 25 is a horizontally extending square cavity connected to the square channel, and each receiving cavity 25 is correspondingly provided with a square-shaped volume adjustment structure 71 that fits into the square receiving cavity 25. It should be noted that when there are multiple hoppers 21 on the base 2, the following can be referred to... Figure 4 and Figure 4.1 The given implementation method is configured.
[0090] This application incorporates a volume adjustment module 7 into the precast component, thereby allowing the volume of the hopper 21 to be adjusted via the volume adjustment module 7. This further aims to adjust the single-discharge amount of the precast component feeding equipment, better meeting the adjustment needs of the discharge amount in the production of different precast components. In specific implementation, the volume adjustment structure 71 can extend from the receiving cavity 25 into the hopper 21, thereby achieving the purpose of adjusting the volume of the hopper 21.
[0091] It should be noted that the shape and size of the volume adjustment structure in this application are not specifically limited, and can be selectively set as needed. For example, the volume adjustment structure 71 can be selectively set to a square shape that is adapted to the receiving cavity 25 (e.g., Figure 4.1 As shown), the receiving cavity 25 is horizontally disposed on the base 2 and slidably adapted to the volume adjustment structure 71. As a variable embodiment, the volume adjustment structure 71 may also be selectively configured as a cylinder, a polygonal prism, etc., and the receiving cavity 25 and the volume adjustment structure 71 may be slidably adapted to each other.
[0092] To better meet the volume adjustment requirements of the hopper 21, the volume adjustment module 7 further includes a third push-pull assembly 72. The third push-pull assembly 72 is mounted on the base 2, with its push-pull end facing the hopper 21 and connected to the volume adjustment structure 71. The third push-pull assembly 72 is configured to drive the volume adjustment structure 71 into the hopper 21.
[0093] In practical operation, the position of the volume adjustment structure 71 is adjusted by pushing and pulling the third push-pull component 72. This application adjusts the position of the volume adjustment structure 71 by using the third push-pull component 72 included in the volume adjustment module 7 to meet the position adjustment needs of the volume adjustment module 7.
[0094] To facilitate installation and make the precast concrete laying equipment more aesthetically pleasing, the first breaking component 3, the second breaking component 4, and the volume adjustment module 7 are all located on the same side of the base 2.
[0095] It should be noted that the third push-pull assembly in this application is not specifically limited, and it can be one of a hydraulic cylinder, a gear and rack linear transmission module, an electric cylinder, or a lead screw and slider linear transmission module. It should also be noted that the third push-pull assembly 72 in this application can also be selectively configured as a manual lead screw and slider linear transmission module or an electrically driven lead screw and slider linear transmission module.
[0096] As some preferred embodiments of this application, the precast component laying device further includes a walking unit 9, which enables the precast component laying device to move at a set position.
[0097] It should be noted that the walking unit in this application is not specifically limited; it can be any unit capable of supporting the movement of the precast concrete placement equipment. Specifically, for example... Figures 1 to 7 As shown, the traveling unit 9 is a traveling trolley, and the precast component placing device is mounted on the traveling trolley. In a specific implementation, the placing device also includes a truss structure capable of supporting the traveling trolley, and the traveling trolley is positioned on the truss structure. During operation, the traveling trolley can move along the truss structure as needed to adjust the position of the placing device. As an alternative implementation, the traveling trolley can optionally be a gantry-type traveling trolley (not shown in the figure), which allows the traveling trolley to move along a ground track during operation.
[0098] This application also provides a preform production line, which includes preform fabrication equipment as described in some of the foregoing embodiments.
[0099] The precast component feeding device included in this application, when in operation, includes the following steps: controlling the second partition plate 41 to block the discharge port of the hopper 21; controlling the first partition plate 31 to connect the inlet of the hopper 21 with the outlet of the hopper 1; controlling the first partition plate 31 to isolate the outlet of the hopper 21 from the outlet of the hopper 1; and controlling the second partition plate 41 to open the outlet of the hopper 21.
[0100] In operation, the precast concrete placing equipment of this application positions at least one of the first partition plate 31 or the second partition plate 41 in a blocked position, and fills the hopper 1 with the prepared concrete. The mold is positioned at a predetermined location below the precast concrete placing equipment.
[0101] Further, by controlling the first partition plate 31 and the second partition plate 41, the hopper 21 is filled with concrete. When concrete needs to be filled into the hopper 21, the first partition plate 31 is controlled to connect the inlet of the hopper 21 with the outlet of the hopper 1, and the second partition plate 41 is positioned to block the outlet of the hopper 21. When the hopper 21 is full, the first partition plate 31 is controlled to isolate the inlet of the hopper 21 from the outlet of the hopper 1, and the second partition plate 41 is further controlled to allow the concrete in the hopper 21 to fall into the mold, and then the outlet of the hopper 21 is blocked by the second partition plate 41. The above process is repeated to realize the precast component placement process.
[0102] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
