Description

Technical Field

[0001] The invention relates to the technical field of precast concrete building material production, and in particular to a precast concrete building material processing machine. Background Art

[0002] Precast concrete building materials refer to building materials made of concrete products in factories. Precast concrete building materials are cast elsewhere rather than at the final construction site. Precast concrete of different sizes and shapes can use fibers to enhance its reliability and toughness after cracking. At the same time, precast concrete has become the new favorite of the construction industry with its low cost and excellent performance. Its various styles, weights, and excellent flexural strength and performance make it widely used in roadblocks, water tanks, exterior walls, construction and decoration.

[0003] For example, a precast concrete building material production and processing equipment with application publication number CN118003453A and publication date 20240510 includes a carrying platform, a feeding assembly and a pressing assembly. Since a precast mold is arranged inside the first precast cavity, and the precast mold is slidably arranged on the precast box, through this arrangement, when the precast mold rises, the concrete above the precast mold will complete the secondary pressing effect of the concrete inside the precast mold under the pressing action of the pressing plate. At the same time, when the precast mold rises to the top, the pressing plate will directly press and smooth the precast mold to complete the third pressing effect of the concrete inside the precast mold. The three pressings also ensure the compactness of the concrete inside the precast mold to a certain extent, so that the concrete raw materials can be fully filled into the precast mold.

[0004] For example, a precast concrete building material production and processing equipment with application publication number CN117207312A and publication date 20231212 includes a supporting base, a connecting spring, a platform body and a vibration motor. A storage hopper is arranged on the top of the platform body, and a material blocking bottom plate is arranged at the bottom of the storage hopper. The connecting spring is fixedly connected to the four corners of the bottom of the platform body, the vibration motor is fixedly connected to the bottom of the platform body, and one end of the connecting spring is fixedly connected to the base plate. This solves the problem that the existing vibration platform is difficult to control the concrete feeding speed when in use, and the vibration of the vibration platform cannot be controlled according to the feeding speed when the concrete falls on the platform. Too long or too fast vibration may make the concrete in the vibration platform insufficiently fluid. When the concrete is insufficiently fluid, the particles cannot be evenly distributed. If the vibration time is too long or the vibration force is too large, gravity will cause the heavier aggregates to settle downward, while the lighter cement slurry will float up, which will easily cause the problem of particle separation.

[0005] When preparing the precast concrete building materials mentioned above and in the prior art, the mold is placed on a conveyor belt, and then the conveyor belt sends the mold to the concrete pouring equipment, and then the concrete is poured. At the same time, the steel frame needs to be manually placed in the mold. This preparation process requires manual placement of the mold into the conveyor belt, which relies heavily on manpower, resulting in a time-consuming and labor-intensive preparation of the building materials. Therefore, it is urgent to design a precast concrete building material processing machine to solve the above problems. Summary of the invention

In this process, the weighing sensor 14 can detect the weight of the weighing hopper 12. When it is detected that the total weight of the weighing hopper 12 reaches a suitable value, the discharge pipe valve 13 will start, so that the concrete inside the weighing hopper 12 will flow into the mold, thereby realizing the quantitative filling of concrete and reducing the waste of concrete resources. The top of the weighing sensor 14 is in contact with the weighing hopper 12.

When concrete building materials are needed later, the electric roller 8 can be operated to start, so that the conveyor belt 3 moves, and then the worker controls the two air pumps 26 to inflate the cavity 23 located above, so that the cavity The piston plate 24 inside the body 23 moves with the conical block 25, so that the conical block 25 clamps the second-to-last mold at the bottom of the storage area 22. At the same time, another air pump 26 is started to extract the air inside the bottom cavity 23, so that the piston plate 24 inside the cavity 23 retracts the conical block 25 into the cavity 23, so that the bottom mold is no longer supported, and the mold falls on the conveyor belt 3, realizing automatic loading of the mold. Later, when the mold is transported to the bottom of the weighing hopper 12, the discharge pipe valve 10 will When the weighing hopper 12 is opened, the concrete inside the mixing box 6 flows into the weighing hopper 12. During this process, the weighing sensor 14 can detect the weight of the weighing hopper 12. When it is detected that the total weight of the weighing hopper 12 reaches a suitable value, the discharge pipe valve 13 will be started, so that the concrete inside the weighing hopper 12 flows into the mold, realizing the quantitative filling of concrete and reducing the waste of concrete resources. After that, as the conveyor belt 3 continues to transport, the mold will move to the bottom of the discharge component 5, and then the two air pumps 2 33 will repeat the above-mentioned air pump 1 26 steps, so that the steel frame automatically falls into the mold with concrete, realizing the automatic feeding of the steel frame, and improving the automation degree of the device. When the mold moves to the bottom of the pressing plate 16, the lifting cylinder 15 will be started, so that the pressing plate 16 is pressed into the mold, thereby compacting the concrete inside the mold. After the compaction is completed, the conveyor belt 3 will move the compacted mold to the bottom of the drying component 17, and then the blower 36 and the heater 37 will be started, so that the hot air is blown onto the concrete in the mold, so as to dry the concrete, which is conducive to accelerating the speed of forming concrete building materials.
