Description

Technical Field

[0001] The utility model relates to the technical field of concrete prefabrication, and more specifically, to a concrete prefabricator. Background Art

[0002] Concrete, abbreviated as "砼", is an artificial stone formed by mixing cementitious materials, aggregates, water (and admixtures and additives may be added when necessary) in a certain proportion, and through stirring, dense molding, and curing and hardening. It is mainly composed of cement, sand, aggregates, and water. Cement is the main cementitious material, which reacts with water to form a cementitious substance that binds sand and aggregates together. Concrete is widely used in civil engineering, such as the construction of infrastructure like buildings, bridges, and roads.

[0003] In the current daily use of concrete, it is often used by bricklayers to stack and extrude precast into blocks for building support structures using tools and simple molds. Manual stacking not only consumes a large amount of labor but also has extremely low efficiency. Therefore, to solve the above problems, the existence of a concrete prefabricator is crucial. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide a concrete prefabricator that can solve the problems raised in the above background art.

[0005] To solve the above technical problems, according to one aspect of the utility model, more specifically, a concrete prefabricator includes a fixed frame. One side of the top of the fixed frame is fixedly provided with a hopper. A conveying hopper is slidably arranged below the hopper inside the fixed frame. An extrusion plate is telescopically arranged on one side of the hopper at the top of the fixed frame. A mold is telescopically arranged below the extrusion plate inside the fixed frame. The bottom of the extrusion plate cooperates with the inner side of the mold. A limiting mechanism is rotatably arranged inside the hopper. Turning mechanisms are fixedly arranged on both sides of the mold. Driving mechanisms are rotatably arranged on both sides of the conveying hopper. A sealing plate is telescopically arranged on the top of the mold. A baffle is fixedly arranged below the conveying hopper inside the fixed frame. One side of the baffle is in close contact with the sealing plate. The bottom of the conveying hopper is in close contact with the baffle and the sealing plate and slides above the baffle and the sealing plate.

[0006] Furthermore, the driving mechanism includes first connecting rods rotatably arranged on both sides of the conveying hopper. One side of each of the two first connecting rods is rotatably connected to a second connecting rod. One side of the two second connecting rods is jointly rotatably connected to a second rotating rod. The second rotating rod is rotatably arranged inside the fixed frame.

[0007] Furthermore, the flipping mechanism includes fixed plates fixedly disposed on both sides of the mold, a motor fixedly disposed on the top of each of the two fixed plates, the output ends of the two motors being fixedly connected to both sides of the mold respectively, and a second telescopic rod fixedly disposed on the top of each of the two fixed plates on both sides of the motor, and the top output ends of the four second telescopic rods being fixedly connected to the bottom of the sealing plate.

[0008] Furthermore, inside the fixed frame, first telescopic rods are fixedly installed on both sides of the extrusion plate, and pull plates are telescopically connected to the bottom of the two first telescopic rods. One side of each of the two pull plates is located below the two fixed plates.

[0009] Furthermore, the limiting mechanism includes a first rotating rod rotatably disposed inside the hopper, and a sealing hopper rotatably disposed outside the first rotating rod, the sealing hopper wrapping around the outside of the hopper.

[0010] Furthermore, a third telescopic rod is telescopically fixedly installed inside the fixed frame at the top of the mold, and the extrusion plate is fixedly connected to the bottom of the third telescopic rod.

[0011] Furthermore, four omnidirectional wheels are fixedly installed at the bottom of the fixed frame.

[0012] The beneficial effects of this utility model of a precast concrete machine are as follows:

[0013] By setting up a conveyor bucket, a mold, and an extrusion plate, concrete material is poured into the hopper during use. After being released by the limiting structure, it enters the conveyor bucket. The conveyor bucket then moves laterally inside the fixed frame to transport the concrete into the mold. At this time, the conveyor bucket detaches from the top of the mold, and the extrusion plate descends to extrude and shape the concrete inside the mold. Finally, after cooling, the extrusion plate and the mold rise together to complete the demolding of the concrete. This effectively realizes the mechanical replacement of manual labor for concrete prefabrication, greatly improving the efficiency of concrete prefabrication.

[0014] By setting up a drive mechanism, stable transportation of concrete materials from the hopper to the mold is achieved. By setting up a tilting mechanism, when concrete precasting is required for molds with different upper and lower widths, the mold rises to a certain position, the second telescopic rod drives the sealing plate to rise to a certain position, and then the motor drives the mold to tilt, thus effectively realizing concrete precasting for molds with different upper and lower widths. The first telescopic rod and the pull plate effectively improve the stability of mold rising. The limit mechanism improves the stability of structural operation. The second telescopic rod effectively improves the stability of die casting. The universal wheels improve the convenience of device transportation. Attached Figure Description

Detailed Implementation

[0022] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0023] like Figures 1-5As shown, according to one aspect of this utility model, a precast concrete machine is provided, including a fixed frame 1. A hopper 4 is fixedly disposed on one side of the top of the fixed frame 1. A conveying hopper 5 is slidably disposed inside the fixed frame 1 below the hopper 4. An extrusion plate 3 is telescopically disposed on the top of the fixed frame 1 on one side of the hopper 4. A mold 2 is telescopically disposed inside the fixed frame 1 below the extrusion plate 3. The bottom of the extrusion plate 3 cooperates with the inner side of the mold 2. A limit mechanism is rotatably disposed inside the hopper 4. A flipping mechanism is fixedly disposed on both sides of the mold 2. A driving mechanism is rotatably disposed on both sides of the conveying hopper 5. A sealing plate 23 is telescopically disposed on the top of the mold 2. A baffle 11 is fixedly disposed inside the fixed frame 1 below the conveying hopper 5. One side of the baffle 11 is connected to the sealing plate 2. Plate 23 fits tightly together, and the bottom of conveying bucket 5 fits tightly with baffle 11 and sealing plate 23 and slides above baffle 11 and sealing plate 23. By setting up conveying bucket 5, mold 2 and extrusion plate 3, concrete material is poured into hopper 4 during use. After the restriction is released by the limiting structure, it enters the interior of conveying bucket 5. Then, conveying bucket 5 moves laterally inside fixed frame 1 to transport concrete into mold 2. At this time, conveying bucket 5 detaches from the top of mold 2, and extrusion plate 3 descends to extrude and shape the concrete inside mold 2. Finally, after cooling, extrusion plate 3 and mold 2 rise together to complete the demolding of concrete. This effectively realizes the mechanical replacement of manual concrete prefabrication and greatly improves the efficiency of concrete prefabrication.

[0024] In this embodiment, the driving mechanism includes first connecting rods 50 rotatably disposed on both sides of the conveying hopper 5, and second connecting rods 51 rotatably connected to one side of each of the two first connecting rods 50. A second rotating rod 52 is rotatably connected to one side of each of the two second connecting rods 51. The second rotating rod 52 is rotatably disposed inside the fixed frame 1.

The output ends of the two motors 24 are respectively fixedly connected to both sides of the mold 2. A second telescopic rod 25 is fixedly disposed on the top of each of the two fixed plates 20 on both sides of the motor 24. The top output ends of the four second telescopic rods 25 are fixedly connected to the bottom of the sealing plate 23. By setting the flipping mechanism, when it is necessary to precast concrete on molds with different upper and lower width requirements, after the mold 2 rises to a certain position, the second telescopic rod 25 drives the sealing plate 23 to rise to a certain position, and then the motor 24 drives the mold 2 to flip, thereby effectively realizing the precast concrete on molds with different upper and lower width requirements.

[0026] In this embodiment, first telescopic rods 22 are fixedly installed inside the fixed frame 1 on both sides of the extrusion plate 3. The bottom of each of the two first telescopic rods 22 is telescopically connected to a pull plate 21. One side of each of the two pull plates 21 is located below the two fixed plates 20. By setting the first telescopic rods 22 and the pull plates 21, the stability of the mold 2 rising is effectively improved.

[0027] In this embodiment, the limiting mechanism includes a first rotating rod 41 rotatably disposed inside the hopper 4, and a sealing hopper 40 rotatably disposed outside the first rotating rod 41. The sealing hopper 40 wraps around the outside of the hopper 4. The limiting mechanism improves the stability of the structure during operation.

[0028] In this embodiment, a third telescopic rod 30 is telescopically fixed inside the fixed frame 1 at the top of the mold 2, and the extrusion plate 3 is fixedly connected to the bottom of the third telescopic rod 30. By setting the third telescopic rod 30, the stability of die casting is effectively improved.
