Description

Technical Field

[0001] The present invention relates to the technical field of concrete vibration equipment, in particular to a concrete vibrating machine. Background Art

[0002] Concrete vibrators are machines that use the vibration of mechanical parts to compact concrete. There are insert-type, attached-type, flat-plate-type and vibrating tables for vibrating precast concrete components. They are widely used on construction sites and concrete product factories. In the existing technology, the total amount of mineral admixtures in the prepared commercial concrete with composite silicate cement having a high admixture content increases, which may lead to the generation of bubbles. In addition, insufficient concrete mixing, uneven vibration or insufficient time will affect the density of the concrete and the uneven distribution of bubbles. Conventional single concrete vibrating tables are difficult to discharge the unevenly distributed bubbles inside the concrete.

[0003] For example, a concrete vibrator with publication number CN110315629A includes a workbench, which includes a contact plate and a mounting plate. The contact plate is located below the mounting plate, and the contact plate and the mounting plate are fixedly connected. A number of sharp objects perpendicular to the contact plate are fixed at the bottom of the contact plate, and a base is fixed on the upper surface of the mounting plate. The base is provided with a vibration device, which has the function of making the concrete more compact and removing the remaining bubbles in the concrete more significantly. However, this method of removing bubbles by synchronous vibration with sharp objects, because the concrete vibrating table usually adopts high-frequency vibration, usually above 2,000 revolutions per minute, and the vibration speed is relatively fast, and during the vibration process, the vibration speed is too fast, which will make the air unable to be effectively discharged, and may even form bubbles, thereby reducing the removal effect of unevenly distributed bubbles and also reducing the vibration processing efficiency. There are certain defects, and the vibration generated by the concrete vibrating body when working is large, and the overall stability of the device is not high.

[0004] Therefore, a concrete vibrating machine is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The object of the present invention is to provide a concrete vibrator to solve the problem that excessively fast vibration speed will result in ineffective exhaust of air and even formation of bubbles, thereby reducing the removal effect of unevenly distributed bubbles.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a concrete vibrator, comprising a base plate, a mold, and a placement plate slidably mounted on the top of the base plate, wherein support rods are symmetrically fixedly connected to the top of the base plate, and the tops of the support rods are fixedly connected to the same top plate, and an electric push rod is fixedly mounted inside the top plate;

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. A removal component is provided. The operator places the mold on the top of the placement plate and fixes it with bolts. Then the electric push rod and the vibration motor unit are started. The vibration motor unit drives the placement plate and the mold to vibrate. The electric push rod drives the top plate to press down. The top plate drives the sealing ring to be pressed tightly on the top of the mold. Then the drive motor is started to work. The drive motor drives the reciprocating screw to rotate slowly. The reciprocating screw drives the side rod and the arc sleeve to rotate. The arc sleeve drives the vertical rod to rotate through the limit block. The vertical rod drives the rotating part to rotate. When the top of the vertical rod contacts the pressure block, the vertical rod is squeezed down by the pressure block.

The reciprocating screw rotation will also drive the movable plate to move up and down, and the movable plate drives the sliding rod and the pressure plate to move up and down, which can remove the bubbles in the middle. When the pressure plate squeezes the inclined surface of the inclined block, the inclined block will drive the cross bar to move, and the cross bar drives the movable block to compress the second spring. When the pressure plate is separated from the inclined surface of the inclined block, the elastic force of the second spring drives the movable block and the cross bar to reset, so that the inclined block and the cross bar will move back and forth horizontally, thereby further increasing the stirring range, facilitating the uniform removal of bubbles inside the concrete, and solving the problem that the air cannot be effectively discharged due to excessive vibration speed, and even bubbles are formed, thereby reducing the removal effect of unevenly distributed bubbles.

[0029] 2. A support rod is provided. Before the device works, the operator rotates the screw part, and the auxiliary rod limits the disc. When the screw part rotates, it drives the disc to move downward, and the disc drives the mounting plate and the rocker arm to move downward. The roller first contacts the ground, and then the rocker arm expands outward. The rotation of the rocker arm drives the rotating shaft to rotate, and the rotating shaft acts on the torsion spring, thereby pressing the disc downward, and the rocker arm assists in expanding. Multiple rocker arms can be symmetrically arranged, which increases the support area and support stability of the bottom of the device, and solves the problem that the vibration generated by the concrete vibrating body during operation is large and the overall stability of the device is not high.

[0055] When the top of the vertical rod 79 contacts the pressure block 710, the vertical rod 79 is squeezed downward by the pressure block 710, and the vertical rod 79 compresses the spring 1 713 and drives the side sleeve 714 to move downward, so that the vertical rod 79 can move back and forth up and down during the rotation, thereby improving the effect of removing bubbles at the bottom.

The vibration motor part 10 drives the placement plate 3 and the mold 11 to vibrate, and the electric push rod 6 drives the top plate 71 to press down, and the top plate 71 drives the sealing ring 72 to be pressed tightly on the top of the mold 11, and then starts the drive motor 74 to work. The drive motor 74 drives the reciprocating screw rod 75 to rotate slowly, and the vertical rod 79 drives the rotating As the movable part 78 rotates, the vertical rod 79 is squeezed and moved downward by the pressure block 710, which facilitates the reciprocating movement of the vertical rod 79 up and down during the rotation, thereby improving the effect of removing bubbles at the bottom. The rotation of the reciprocating screw 75 will also drive the movable disk 721 to move up and down, and the movable disk 721 drives the sliding rod 722 and the pressure plate 723 to move up and down to remove bubbles in the middle.
