A high-efficiency leveling and defoaming mechanism for self-leveling mortar

Abstract

This invention discloses a high-efficiency leveling and defoaming mechanism for self-leveling mortar, comprising a main body with an installation groove, wheels on the lower ends of both sides of the main body, a cover within the installation groove that slides within the groove, a first automatic telescopic rod at the upper end of the cover connected to the installation groove, a vacuum pump at the upper end of the cover with an air inlet connected to an air pipe, and a barometer inside the cover, a sealing ring at the lower end of the cover, and a control panel at the upper end of the main body. In this invention, the cover is pushed downwards by the first automatic telescopic rod, covering the self-leveling mortar laid on the ground. The sealing ring creates a relatively sealed environment. The vacuum pump operates to remove air from inside the cover, reducing the air pressure. As the air pressure decreases, air bubbles in the mortar expand, float to the surface, and burst, effectively removing air bubbles from the self-leveling mortar and ensuring the construction effect of the self-leveling mortar.

Description

Technical Field

[0001] This invention relates to the field of leveling and defoaming technology, and in particular to a high-efficiency leveling and defoaming mechanism for self-leveling mortar. Background Technology

[0002] Self-leveling mortar is an ideal water-based rigid inorganic composite foundation material. Its main components are special cement, fine aggregates, binders, and various additives. It is suitable for laying various types of industrial floors, offering high surface strength and excellent wear resistance. It is primarily used in new construction or renovation projects, as well as for fine leveling of industrial floors. Furthermore, it hardens quickly, allowing walking on it within 24 hours, facilitating subsequent work (such as laying wood flooring or engineered wood flooring). Its rapid and simple construction is unmatched by traditional manual leveling methods.

[0003] During the construction of self-leveling mortar, a defoaming roller is needed to defoam the substrate, that is, to remove the air bubbles in the substrate to ensure the uniform texture of the substrate. The defoaming roller mainly squeezes out the air bubbles by puncturing them. It only has a significant release effect on the air bubbles that are in contact with the needle. For the air bubbles around the needle, its release effect is limited, resulting in poor defoaming effect and affecting the construction effect of self-leveling mortar. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency leveling and defoaming mechanism for self-leveling mortar. By pressing down the cover, the self-leveling mortar laid on the ground is covered, and the vacuum pump sucks away the air. The air pressure inside the cover decreases, and the bubbles expand and burst, solving the problem that the defoaming effect of the defoaming roller is poor and affects the construction effect of the self-leveling mortar.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A self-leveling mortar high-efficiency leveling and defoaming mechanism includes a main body with an installation groove having an opening at the bottom. Wheels are provided at the bottom ends of both sides of the main body. A cover with an opening at the bottom is provided within the installation groove, and the cover slides into the installation groove. A first automatic telescopic rod is vertically mounted on the upper end of the cover. A pressure sensor is provided between the first automatic telescopic rod and the cover. The upper end of the first automatic telescopic rod is connected to the installation groove. A vacuum pump is provided on the upper end of the cover. An air inlet of the vacuum pump is connected to an air pipe. The end of the air pipe away from the vacuum pump is connected to the cover. A barometer is provided inside the cover. A sealing ring is installed at the lower end of the cover. A control panel is provided on the upper end of the main body. The first automatic telescopic rod, vacuum pump, pressure sensor, and barometer are all electrically connected to the control panel.

[0007] A further feature of the present invention is that a secondary pipe is connected to the trachea, and a solenoid valve is connected to the secondary pipe, the solenoid valve being electrically connected to the control panel.

[0008] A further configuration of the present invention is as follows: a support plate is horizontally provided inside the cover, a plurality of defoaming needles are evenly provided at the lower end of the support plate, and a plurality of second automatic telescopic rods are vertically connected to the upper end of the support plate. The upper end of the second automatic telescopic rods is connected to the cover, and the second automatic telescopic rods are electrically connected to the control panel.

[0009] A further feature of the present invention is that the support plate and the second automatic telescopic rod are connected by an elastic element, a vibration motor is provided at the upper middle part of the support plate, the vibration motor is electrically connected to the control panel, and a plurality of through holes are vertically provided on the support plate.

[0010] A further provision of the present invention is that the elastic element is a spring.

[0011] A further feature of the present invention is that the main body is provided with a handle, the handle is provided with a control switch, and the control switch is electrically connected to the control panel.

[0012] A further feature of the present invention is that the main body has an air outlet for use in conjunction with the vacuum pump.

[0013] In summary, the present invention has the following beneficial effects:

[0014] Firstly, in this invention, the cover is pushed downward by the first automatic telescopic rod, covering the self-leveling mortar laid on the ground. The sealing ring forms a relatively sealed environment. The vacuum pump works to suck away the air inside the cover, reducing the air pressure inside the cover. When the air pressure decreases, the air bubbles in the mortar will expand, float to the surface, and burst, effectively removing the air bubbles in the self-leveling mortar and ensuring the construction effect of the self-leveling mortar.

[0015] Secondly, in this invention, while the cover body reduces the air pressure, the second automatic telescopic rod pushes the support plate downward, inserts the defoaming needle into the mortar, and defoams it. Then, the support plate is vibrated by the vibration motor, which makes the defoaming needle stir the mortar, making the air bubbles in the high-viscosity mortar easier to rise to the surface and break, further enhancing the defoaming effect.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Example: A high-efficiency leveling and defoaming mechanism for self-leveling mortar, such as... Figures 1 to 3As shown, the device includes a main body 1 with a mounting groove 11 having an opening at the bottom. Wheels 12 are located at the bottom of both sides of the main body 1, facilitating movement of the device. A cover 2 with an opening at the bottom is located within the mounting groove 11, slidingly engaging with the mounting groove 11. A first automatic telescopic rod 3 is vertically mounted on the upper end of the cover 2. A pressure sensor 31 is located between the first automatic telescopic rod 3 and the cover 2, detecting pressure to control the downward pressure length of the cover 2. The upper end of the first automatic telescopic rod 3 is connected to the mounting groove 11, and the first automatic telescopic rod 3 drives the cover 2 to slide up and down, covering the cover 2 onto the mortar. A vacuum pump 4 is installed at the upper end of the cover 2. The air inlet of the vacuum pump 4 is connected to an air pipe 41. The end of the air pipe 41 away from the vacuum pump 4 is connected to the cover 2. A barometer 21 is installed inside the cover 2. A secondary pipe 42 is connected to the air pipe 41, and a solenoid valve 43 is connected to the secondary pipe 42. The vacuum pump 4 is used to extract air from the cover 2, reducing the air pressure inside the cover 2, which facilitates the elimination of air bubbles in the mortar. Both the air pipe 41 and the secondary pipe 42 are negative pressure resistant pipes, which can be flexible or rigid pipes. The barometer 21 is used to detect the air pressure inside the cover 2 for easy control. The solenoid valve 43 and the secondary pipe 42 facilitate opening the air inlet to restore the air pressure. A sealing ring 22 is installed at the lower end of the cover 2. The sealing ring 22 can enhance the seal between the cover 2 and the ground, preventing mortar from outside the cover 2 from entering and affecting the defoaming effect. The upper part of the main body 1 is equipped with a control panel 13. The first automatic telescopic rod 3, solenoid valve 43, vacuum pump 4, pressure sensor 31 and barometer 21 are all electrically connected to the control panel 13. Construction personnel can control the various electronic components to work together by operating the control panel 13.

[0025] A support plate 5 is horizontally arranged inside the cover 2. Several defoaming needles 51 are evenly arranged at the lower end of the support plate 5. Several second automatic telescopic rods 6 are vertically connected to the upper end of the support plate 5. The upper ends of the second automatic telescopic rods 6 are connected to the cover 2 and electrically connected to the control panel 13. The support plate 5 and the second automatic telescopic rods 6 are connected by an elastic element 61. A vibration motor 52 is located in the middle of the upper end of the support plate 5 and is electrically connected to the control panel 13. Several through holes 53 are vertically opened on the support plate 5. Specifically, in this embodiment, the elastic element 61 is a spring, but it could also be a rubber block, ensuring the vibration effect of the vibration motor 52 on the support plate 5. In use, the support plate 5 is pushed up and down by the second automatic telescopic rods 6, adjusting the insertion depth of the defoaming needles 51 to defoam the expanded bubbles. Then, the vibration motor 52 operates, driving the defoaming needles 51 to vibrate and stir the mortar, making it easier for bubbles in the high-viscosity mortar to float to the surface and break, further enhancing the defoaming effect.

[0026] The main body 1 is equipped with a handle 7, and a control switch 71 is mounted on the handle 7. The control switch 71 is electrically connected to the control panel 13. The handle 7 facilitates pushing or pulling the device to change its position, while the control switch 71 can directly control the operation of each electronic component, making operation convenient.

[0027] The main body 1 has an air outlet 14 for use with the vacuum pump 4, which facilitates exhaust.

[0028] It should be noted that in this embodiment, both the first automatic telescopic rod 3 and the second automatic telescopic rod 6 are telescopic motors. Of course, they can also be components such as cylinders or hydraulic cylinders, as long as they meet the required functions.

[0029] Instructions for use: After the worker lays the self-leveling mortar on the ground, they push the device to operate sequentially. Before operation, the air pressure value is set according to the viscosity and thickness of the mortar. The more viscous and thicker the mortar, the lower the required air pressure. The depth of insertion of the defoaming needle 51 is then set, generally to 2 / 3 of the mortar thickness. It should not be too deep or too shallow. Too deep, and the defoaming needle 51 may be damaged on uneven surfaces; too shallow, and the defoaming effect will be poor. After pressing the control switch 71, the cover 2 is pushed downward by the first automatic telescopic rod 3, covering the self-leveling mortar laid on the upper part of the ground. The sealing ring 22 forms a relatively sealed environment. Since the ground may be uneven, the initial leveling is more important than the existing construction process. The vacuum pump 4 works to suck away the air inside the cover 2, reducing the air pressure inside the cover 2. When the air pressure decreases, the air bubbles in the mortar will expand, float to the surface, and burst. During the operation of vacuum pump 4, the second automatic telescopic rod 6 pushes the support plate 5 downward, inserts the defoaming needle 51 into the mortar, and defoams it. Then, the vibration motor 52 vibrates the support plate 5, allowing the defoaming needle 51 to stir the mortar, making it easier for the air bubbles in the high-viscosity mortar to rise to the surface and break. Of course, the support plate 5 can also be moved up and down multiple times to achieve the defoaming effect.

[0030] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
