[0094] The cleaning plate 58 rotates to contact the lower end surface of the pressing plate 44.

[0095] A paving method of a metering pressure-injection material spreading device comprises the following steps:

[0096] S1. The trolley is located below the frame body 1 and moves, and the concrete components are prefabricated thereon:

[0097] S1.1. When prefabricating concrete components, the trolley moves to a suitable position, and the storage mechanism 2 stirs and mixes the concrete, and the concrete falls into the metering mechanism 3 after stirring and mixing;

[0098] S1.2, the metering mechanism 3 sets a preset value, and when the set weight is reached, the storage mechanism 2 closes and the weighing is completed;

[0099] S2. Closed frame settings:

[0100] The grabbing mechanism 6 grabs the belt blocking mechanism 7 mounted on the frame body 1, and places the grabbing belt blocking mechanism 7 at a preset position of the trolley, so that a closed frame is formed between the belt blocking mechanism 7 and the frame body 1, and the concrete measured by the measuring mechanism 3 is poured into the closed frame;

[0101] S3, vibration flattening treatment:

[0102] The pressing mechanism 4 is started, driving the pressing plate 44 downward to press the concrete in the closed frame. During the pressing process of the pressing plate 44, the concrete is vibrated to discharge the bubbles inside the concrete.

[0103] S4, closed frame alternate setting:

[0104] After the concrete in the closed frame is compacted, the grabbing mechanism 6 grabs the belt blocking mechanism 7 that has blocked the concrete, so that the belt blocking mechanism 7 is placed again at another preset position of the trolley to form a new closed frame.

[0105] Furthermore, a paving method of a metered pressure-injection material spreading device further includes a cleaning process, wherein the cleaning process includes the following steps:

[0106] After the material is vibrated and smoothed, the pressing mechanism 4 is lifted upward, the cleaning mechanism 5 is started, and the cleaning mechanism 5 controls the cleaning plate 58 to perform a cleaning operation on the pressing mechanism 4 .

[0107] Concrete components are prefabricated on a trolley, and the trolley is located under the frame body 1 for movement. When in use, concrete raw materials are stored and mixed in the storage mechanism 2. When prefabricating concrete, the trolley moves to a suitable position and stops, and the concrete falls from the storage mechanism 2 to the metering mechanism 3. The metering mechanism 3 weighs and quantitatively controls the required amount of concrete to prevent the amount of concrete in the metering mechanism 3 from exceeding a preset range. After the metering mechanism 3 receives the concrete material, it is controlled to move on the frame body 1 by a mobile control component, and the moving direction is consistent with the moving direction of the trolley under the frame body 1, wherein the mobile control component is configured as an electric drive trolley; the grabbing mechanism 6 on the metering mechanism 3 grabs the belt blocking mechanism 7, and moves it to a suitable position for lowering, so that a pair of belt blocking mechanisms 7 and the peripheral closed frame formed at the edge of the trolley can limit the concrete distribution, facilitate the adjustment of the size of the concrete slab and beam, and then the metering mechanism 3 discharges the precisely measured concrete into the closed frame.

[0108] The pressing mechanism 4 is started, driving the pressing plate 44 downward to press the concrete in the closed frame. During the pressing process, the vibration device on the pressing plate 44 vibrates the material to expel the bubbles therein, so as to avoid bubbles in the precast concrete affecting the overall quality during the laying. After the concrete is vibrated smoothly, the pressing mechanism 4 is lifted to a certain height, thus completing a cycle, and then the trolley continues to move to the next position. Therefore, the metering pressure-casting material spreading device can realize accurate metering of precast concrete components, material laying, flattening and vibration; in addition, the cleaning mechanism 5 can be used to clean the lower end of the pressing plate 44 to avoid the concrete from solidifying on the pressing plate 44 and affecting the flatness of the lower end surface of the pressing plate 44.

[0109] Specifically, concrete enters the storage hopper 21 from the upper end of the storage hopper 21, and the first motor 23 is started to drive the five-star wheel 24 to rotate, which not only realizes the storage of materials in the storage hopper 21, but also facilitates the control of the material falling from the lower end of the storage hopper 21. At the same time, the concrete can be stirred to prevent it from hardening inside the storage hopper 21; when the metering mechanism 3 is located below the storage mechanism 2 and the concrete components are prefabricated, the first drive motor 25 is started to drive the first switch door 26 to open. Preferably, the first switch door 26 can be hingedly installed at the lower end of the storage hopper 21, and the first drive motor 25 drives the first switch door 26 to rotate and open.

[0110] The material falling into the measuring bucket 31 is weighed by a weighing device connected to the support frame 36, and the weight is fed back to the controller in real time. The controller is electrically connected to the weighing device. When the weight of the material reaches a preset range, the controller controls the first drive motor 25 to control the first switch door 26 to close and stop unloading, thereby achieving accurate measurement of the material; and when the metering mechanism 3 unloads the material, it can be opened in the form of a double door, that is, a pair of second switch doors 35 at the lower end of the measuring bucket 31 open and close each other, and each second switch door 35 is opened and closed by the second drive motor 34.

[0111] The metering mechanism 3 moves on the frame body 1, and the second motor 32 drives the first gear 33 to mesh with the first rack located on the frame body 1, so as to realize the overall movement of the support frame 36;

[0112] Before unloading the trolley, the belt blocking mechanism 7 is placed, that is, the metering mechanism 3 is provided with a grabbing mechanism 6 for grabbing and releasing the belt blocking mechanism 7; preferably, a storage place for the belt blocking mechanism 7 is provided on the frame main body 1, and there are at least two belt blocking mechanisms 7, the belt blocking mechanism 7 is hung on the frame main body 1, and hooks are provided at both ends of the belt blocking plate 73, and the hooks are quickly hung on the frame main body 1, so that the belt blocking mechanism 7 can be quickly grabbed and released; when the metering mechanism 3 moves to the belt blocking mechanism 7, the height of the support rod 62 is driven by the hydraulic telescopic rod 61 to adjust the height of the support rod 62, so that the grabbing assembly on it is located at the belt blocking mechanism 7, the second driving electric cylinder 63 is started, and the grabbing rod 64 is driven to be inserted into the through hole of the grabbing block 71 on the belt blocking mechanism 7 to grab the belt blocking mechanism 7, and preferably, a positioning rod 72 is provided on the upper end of the belt blocking plate 73, which is sleeved in the positioning sleeve 65 on the support rod 62, so that the positioning of the grabbing mechanism 6 is achieved by matching the positioning rod 72 with the positioning sleeve 65;

[0113] With respect to the arrangement of the belt blocking mechanism 7, the present invention will be further described below in conjunction with embodiments.

[0114] like Fig.11 , Fig.12As shown, the two belt blocking mechanisms 7 are numbered A and B respectively. First, the belt blocking mechanisms A and B can be sequentially lowered onto the platform S vehicle through the grabbing mechanism 6 according to the actual use situation. Fig.11 , Fig.12 Described in the left and right directions, the belt blocking mechanism A is placed on the left side of the belt blocking mechanism B, and the trolley S moves to the right. At this time, the belt blocking mechanisms A and B form a closed frame I with the trolley S, and the concrete material is placed in the closed frame I; after the concrete in the closed frame I is laid, the metering mechanism 3 returns to the initial position to continue metering and receiving the material, and the trolley S moves to the right by the spacing of a precast concrete component. The metering mechanism 3 drives the grabbing mechanism 6 to move to the belt blocking mechanism B to grab it, and then lowers it to the left side of the belt blocking mechanism A to form a closed frame II with the belt blocking mechanism A and the trolley S, and the concrete material is placed in the closed frame II;

[0115] like Fig.11 , Fig.12 As shown, after the concrete is laid in the closed frame II, the metering mechanism 3 returns to the initial position to continue metering the material, and the trolley S moves to the right by the spacing of a precast concrete component. The metering mechanism 3 drives the grabbing mechanism 6 to move to the belt blocking mechanism A to grab it, and then lowers it to the left side of the belt blocking mechanism B to form a closed frame III with the belt blocking mechanism A and the trolley S. The concrete material is placed in the closed frame III and circulated in sequence, thereby avoiding manual operation and realizing the automatic arrangement of the belt blocking mechanism 7, which is more efficient.

[0116] When a pair of belt retaining mechanisms 7 are lowered onto the trolley and a peripheral closed frame is formed with the edge of the trolley, the metering mechanism 3 unloads the concrete into the closed frame, thereby realizing the distribution of the concrete, and the metering mechanism 3 moves to the initial position, that is, below the storage mechanism 2; then the pressing mechanism 4 is started, and the hydraulic telescopic rod 61 drives the pressing plate 44 to move downward to compact the concrete, and at the same time, the first driving electric cylinder 42 drives the vibrating rod 43 on the mounting frame 41 to be inserted into the concrete for vibration, and there can be multiple vibrating rods 43, thereby realizing the vibration of the concrete.

[0117] When the flattening and vibration are completed, the hydraulic telescopic rod 61 drives the pressing plate 44 to move upward. At this time, the cleaning mechanism 5 is started, that is, the fourth motor 57 drives the cleaning plate 58 to rotate to the bottom of the pressing plate 44 through the gear set, and the scraper structure on the cleaning plate 58 is attached to the lower end surface of the pressing plate 44, and the collection box structure at the lower part is used to collect the scraped material. The third motor 55 is started, driving the second gear 56 to rotate and mesh with the second rack 52. Therefore, the movable frame 54 moves on the frame body 1 under the limit of the guide rod 53, that is, the moving direction is perpendicular to the moving direction of the trolley. At this time, the cleaning plate 58 cleans the lower end of the pressing plate 44 to avoid the presence of adsorbents on the lower end surface of the pressing plate 44, which affects the next pressing; when the cleaning process is completed, the third motor 55 rotates in the opposite direction, driving the cleaning plate 58 to rotate to avoid the pressing mechanism 4, so that the pressing mechanism 4 will collide with the cleaning mechanism 5 when it is lifted next time.

[0118] The present invention relates to a metering pressure-casting material spreading device and a spreading method thereof. The material storage mechanism 2 and the metering mechanism 3 are used to achieve weighing and metering of the concrete material, which is convenient for better control and operation. The metering mechanism 3 is movably arranged on the frame body 1, and the grabbing mechanism 6 thereon grabs and releases the belt blocking mechanism 7 to form a closed frame, and the concrete material is fed into the closed frame to achieve the prefabricated material distribution of concrete components. The lifting and lowering pressure plate 44 of the pressing mechanism 4 and the vibration device for vibrating and leveling the material are used to achieve the leveling and vibration of the concrete material. Therefore, the system realizes the precise metering of the material distribution, leveling and vibration of the prefabricated concrete components, which saves resources and is more efficient, and avoids the situation that the traditional leveling equipment needs manual participation and the equipment is complicated to use. In addition, a cleaning mechanism 5 is provided to clean the lower end of the pressing plate 44 to avoid the concrete adhering to the pressing plate 44 and solidifying, thereby affecting the flatness of the lower end surface of the pressing plate 44.

[0119] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
