Description

Technical Field

[0001] The utility model relates to the removal of bubbles in concrete, in particular to a vibration device for removing bubbles in concrete. Background Art

[0002] When constructing concrete floors or prefabricated slabs and self-leveling mortar, bubbles will enter the concrete during mixing. If the bubbles cannot be eliminated in time, pores will form after the concrete hydration reaction, which will have an adverse effect on the appearance and strength of the concrete or self-leveling mortar. Therefore, defoaming must be performed when constructing prefabricated concrete slabs or self-leveling mortar.

[0003] The concrete defoaming device currently used in construction is mainly an ordinary defoaming roller, which is composed of a stainless steel frame, heat-resistant silicone coated outside the frame and a connecting rod, has low efficiency and poor defoaming effect. Utility Model Content

[0006] The utility model is further configured that a control power supply electrically connected to all vibrators is provided inside the mounting end of the roller shaft, and a control switch electrically connected to the control power supply is provided outside.

[0007] The utility model is further configured that the number of the positioning posts is two or three, and the number of the positioning grooves is the same as that of the positioning posts.

[0008] Beneficial effects of the utility model:

[0009] 1. A plurality of S-shaped stirring blades are arranged on the roller shaft along its axial direction, and thorns are provided on the S-shaped stirring blades. While the roller shaft rotates, air bubbles in the concrete slurry are removed. At the same time, vibrators connected to each S-shaped stirring blade are provided to shake off the concrete slurry on the S-shaped stirring blades and the roller shaft while eliminating air bubbles;

[0010] 2. The power device and the roller shaft are inserted and positioned through the installation notch and the positioning column, and the positioning column can be fixed in the positioning groove by the locking nut, so that the power device and the roller shaft are more firmly fixedly connected. Through the setting of the locking nut, the roller shaft can be quickly loaded and unloaded after work, which is convenient to use and has low labor intensity. Brief Description of the Drawings

[0014] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0015] As Figure 1 shown, a concrete air bubble removal and vibration device includes a roller shaft 1 and a power device 2 for driving the roller shaft 1 to rotate. The roller shaft 1 is evenly spaced with S-shaped stirring blades 3. The middle part of the S-shaped stirring blade 3 penetrates through the roller shaft 1. Inside the roller shaft 1, vibrators 4 connected to each S-shaped stirring blade 3 are installed at intervals. Thorns 31 are evenly arranged on the outer arc surface of the S-shaped stirring blade 3; A control power supply 5 electrically connected to all vibrators 4 is arranged inside the installation end of the roller shaft 1, and a control switch 51 electrically connected to the control power supply 5 is arranged outside.

[0016] In the above structure, by arranging a plurality of S-shaped stirring blades 3 distributed along the axial direction on the roller shaft 1, and thorns 31 are provided on the outer arc surface of the S-shaped stirring blade 3, this structural design can effectively eliminate the air bubbles in the concrete slurry while the roller shaft 1 rotates. A vibrator 4 connected to each S-shaped stirring blade 3 is also arranged inside the roller shaft 1. During the rotation and vibration of the S-shaped stirring blade 3, the air bubbles in the concrete can be eliminated more efficiently and effectively. At the same time, the concrete slurry on the S-shaped stirring blade 3 and the roller shaft 1 can be shaken off; the vibrator 4 and the control power supply 5 for controlling the operation of the vibrator 4 are both installed inside the roller shaft 1, which is beneficial to protecting the vibrator 4 and the control power supply 5 from being polluted and damaged by the concrete and improving the service life of the equipment.

[0017] As Figure 1 and Figure 2 shown, a positioning column 11 extends radially outward from the installation end of the roller shaft 1. An installation notch 21 is provided at the output end of the power device 2. The installation end of the roller shaft 1 can be adaptively inserted into the installation notch 21. A positioning groove 22 through which the positioning column 11 is adapted to penetrate is opened on the groove wall of the installation notch 21. A locking nut 6 for detachably plugging and installing the roller shaft 1 and the power device 2 is threadedly sleeved on the outer groove wall of the installation notch 21. There are two or three positioning columns 11, and the same number of corresponding positioning grooves 22 are provided.

[0018] In the above structure, the output end of the power device 2 and the roller shaft 1 are positioned by the plug-in fit of the installation notch 21 and the positioning column 11, and then the positioning column 11 is fixed in the positioning groove 22 by the locking nut 6, positioning the installation end of the roller shaft 1 in both the axial and radial directions, so that the power device 2 and the roller shaft 1 are more firmly fixedly connected. Two or three groups of positioning columns 11 and positioning grooves 22 can be provided, which simplifies the structure while achieving the positioning effect; through the setting of the locking nut 6, the roller shaft 1 can be quickly loaded and unloaded and cleaned after the vibration device works, which is convenient to use and has a small labor intensity.

[0019] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made. These improvements and modifications should also be regarded as the protection scope of the present invention.
