Description

Technical Field

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

[0002] Concrete is a commonly used building material, which is a mixture of sand, cementitious materials and mud. It is necessary to stir the concrete through a mixing device to mix the various components in the concrete evenly. Concrete precast components, also known as concrete blocks, can be obtained by molding concrete mortar in a special mold through extrusion, vibration and other methods to obtain concrete precast components of corresponding shapes. Concrete precast components can be used for wall masonry or sidewalk paving. Concrete precast components are widely used in existing construction projects. Precast concrete components are concrete mixed with water and stirred to adjust the concrete collapse to a condition greater than 0mm, and then the concrete is poured into a mold with reinforcements (such as steel bars) placed, and the concrete is vibrated with a vibrator to eliminate the pores in the concrete as much as possible and increase the strength of the finished product. The poured and vibrated concrete needs to be left to stand for a period of time until the concrete is completely solidified. The mold can be removed only after the concrete hardens to a certain strength. Due to the long standing time and the need to remove the precast concrete components from the mold piece by piece, a large amount of molds and manpower are required. Summary of the invention

[0003] The present invention is intended to provide a concrete processing device to solve the problem that a large amount of molds and manpower are required during the concrete mixing process in the prior art.

[0004] A concrete processing device of the present invention comprises a vibration table and a mold, wherein the mold is located on the vibration table, and the mold comprises a rectangular bottom mold box, wherein the bottom mold box comprises a bottom mold plate and side panels located on both sides of the long sides of the bottom mold plate, and the two sides and the top of the short sides of the bottom mold plate are open, and a plurality of notches are arranged on the two side panels, and a plurality of partitions matching the notches are respectively arranged at both ends of the side panels, and the partitions and the side panels constitute a plurality of mold cavities arranged in sequence, and the partitions on the same side are fixedly connected to the same rotating shaft, and the rotating shaft is arranged at the top of the side panel and is hinged to the support arranged at the top of the side panel; a push rod facing the bottom mold box is arranged on one side of the short side of the bottom mold box, and a conveyor belt for conveying prefabricated concrete components is arranged on the other side of the short side of the bottom mold box.

[0005] The working principle of the present invention is that a concrete processing equipment of the present invention is mainly composed of a vibration table, a mold, a push rod and a conveyor belt, wherein the mold is set on the vibration table, and the concrete is vibrated and compacted with the vibration of the vibration table to eliminate the pores in the concrete and increase the strength of the finished product. The mold is composed of a bottom mold box and a partition. The bottom mold box is a rectangular parallelepiped with open ends and a top, and a notch is set on the rectangular parallelepiped. The partitions are fixed on the rotating shaft. When the rotating shaft is set on the side panel, the rotating shaft can be rotated to insert the partition into the notch to form independent mold cavities, and concrete is loaded into the mold cavity, and then the vibration table is started. The vibrator vibrates the concrete to eliminate the pores in the concrete and increase the strength of the finished product. The poured and vibrated concrete needs to be left to stand for a period of time. At this time, the vibration table is turned off and the concrete is left to stand until the concrete is completely solidified. After the concrete hardens to a certain strength, a precast concrete component is formed. At this time, the shaft is rotated to pull the partition out of the gap. At this time, there is no obstruction between the two adjacent precast concrete components. Move the push rod, hold the push rod against the nearest precast concrete component, and push it toward the conveyor belt. The precast concrete components can be pushed toward the conveyor belt one by one. The conveyor belt is driven to transmit the precast concrete components.

[0006] Beneficial effects of the present invention: The concrete processing equipment of the present invention, based on the problem that the prior art requires the coordination of multiple molds and requires a large amount of manpower for demolding, sets the mold to consist of a bottom mold box with multiple notches and multiple partitions. The multiple partitions and two side panels constitute multiple mold cavities arranged in sequence, avoiding the problem of needing multiple molds. Since the partitions can be adapted to the notches by rotation, when demolding is required, the partitions are removed and the push rod is pushed to push down multiple hardened precast concrete components one by one and send them to the conveyor belt, solving the problem of demolding requiring a large amount of manpower and material resources.

[0007] The molds of the present invention can be arranged in parallel in multiple numbers, and the push rods can be manually or electrically driven.

[0008] Preferably, the notches on the two side panels are arranged in a staggered manner, and the partitions on the same side are opposite to the notches on the same side. The notches are staggered, one partition corresponds to one notch, and the partitions on different sides are staggered accordingly. This arrangement can ensure that a precast concrete component only interacts with one partition, reducing the difficulty of demoulding.

[0009] Preferably, the bottom mold box is provided with a cavity, and a constant temperature fluid is provided in the cavity. In order to accelerate the hardening speed of concrete, the temperature most suitable for the current hardening is selected, the bottom mold box is hollowed out, a cavity is provided, and a constant temperature fluid is introduced into the cavity to accelerate the hardening speed.

[0010] Preferably, a lifting and lowering pressing plate assembly is connected to the vibration table, and a pressing plate facing the mold cavity is provided on the pressing plate assembly.

[0011] Furthermore, a pressure rod is provided on the pressure plate.

[0012] In order to make the precast concrete components stronger and have fewer internal bubbles, a pressure plate assembly is provided to press the concrete in the mold cavity to accelerate the speed of vibration compaction. At the same time, the pressure rod provided on the pressure plate also helps to squeeze the bubbles in the concrete.

[0013] Of course, the pressure rod is set to move up and down.

[0014] Furthermore, there are at least two molds, which are arranged in parallel, and the pressing plate assembly is arranged at the outermost ends of the two molds. The molds can be arranged in multiple groups to reduce the floor space and increase the output. In the present invention, two groups are preferred, and the pressing plate assembly is arranged at the outermost ends of the two molds.

[0015] Furthermore, a push plate is provided at the free end of the push rod, and the bottom end of the push plate is slidably connected to the bottom template. The push plate is provided to increase the effective area, and the push plate is slidably connected to the bottom template to ensure the demoulding effect.

[0016] Similarly, the positions of the bottom mold box and the partition board that are in contact with the precast concrete components are sprayed with a release agent. In order to make demoulding smoother, the places that are in contact with the precast concrete components are all sprayed with a release agent to reduce demoulding resistance.

[0017] Further, it also comprises a release agent spraying pipe, which is a flexible pipe body, and the nozzle of the spraying pipe faces the mold. By setting the release agent spraying pipe loaded with the release agent, the release agent spraying pipe is movable, so it is convenient for spraying. BRIEF DESCRIPTION OF THE DRAWINGS
