Description

Technical Field

[0001] The present invention relates to the technical field of plastering tools, and specifically to a new type of multi-functional trowel with automatic mortar output and a plastering method. Background Art

[0002] Plastering work has always played an important role in the construction field, and it has a significant impact on the quality of the living environment and building energy consumption. At present, plastering work is mainly completed manually, and robot plastering is emerging, but the complete set of technologies is not yet mature. Therefore, plastering equipment is crucial for construction efficiency and quality.

[0003] At the present stage, manual plastering mainly uses a wooden trowel or a steel trowel and is operated in cooperation with a scraper. For each piece plastered, manual shoveling of ash and replenishing of materials are required, which is extremely labor-consuming. Secondly, during the operation of traditional plastering tools, mortar is likely to fall off, especially in complex environments, and the mortar loss is more serious. Moreover, it is very difficult to achieve a suitable and uniform humidity on the wall before plastering, so it is very difficult to ensure uniform quality when using traditional plastering tools for plastering. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a new type of multi-functional trowel with automatic mortar output and a plastering method to solve the technical problems in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A new type of multi-functional trowel with automatic mortar output, including an integrated handle, which is composed of a mortar output grip, a connecting pipe, and a connecting head;

[0006] The lower part of the integrated handle is connected to a flat trowel through a connecting pipe, and a multi-functional trowel plate is detachably connected to the bottom end inside the flat trowel. The cavity opened inside the multi-functional trowel plate is communicated with the mortar output grip through the connecting pipe, and a discharge port is opened at the bottom of the multi-functional trowel plate. A flow rate control mechanism is arranged inside the mortar output grip;

[0007] The flow rate control mechanism includes a regulating valve plate, a rotating shaft, a gear, and a rack. The regulating valve plate is located inside the mortar output grip and is rotatably connected thereto through the rotating shaft. A gear is fixed on one side of the rotating shaft, and a rack meshing with the gear is slidably connected to one side inside the mortar output grip;

[0008] The flow rate control mechanism further includes a connecting plate, an adjusting slider, a movable shaft, an elastic piece, a locking tooth, and a card slot. The connecting plate is fixed at the end of the rack, and an adjusting slider is rotatably connected to the outside of the connecting plate through the movable shaft. One end of the adjusting slider and the connecting plate are elastically connected through the elastic piece, and the locking tooth is fixed at the other end of the bottom of the adjusting slider. Multiple groups of card slots matching with the locking tooth are opened on the surface of the mortar output grip;

[0009] A connecting sleeve mechanism that matches the connecting pipe is provided at the top of the flat trowel. A water delivery pipe with one end extending into the interior of the connecting pipe is fixed to the top of the grout delivery grip, and the other end of the water delivery pipe is communicated with an external water supply tank;

[0010] A locking member for locking the flat trowel and the connecting pipe is provided on one side of the connecting sleeve mechanism. The connecting sleeve mechanism is a first sleeve, and the flat trowel and the connecting pipe are connected to each other through the first sleeve;

[0011] The multi-functional trowel plate can be a round-hole discharging trowel plate, and a plurality of groups of round discharging ports are opened at the bottom of the round-hole discharging trowel plate;

[0012] The multi-functional trowel plate can be a rectangular discharging trowel plate, and a plurality of groups of rectangular discharging ports are opened at the bottom of the rectangular discharging trowel plate;

[0013] The multi-functional trowel plate can be a rolling brush trowel plate, and a plurality of groups of rolling brushes are rotatably connected to the bottom of the rolling brush trowel plate. A plurality of groups of gaps that match the plurality of groups of rolling brushes are opened at the bottom of the rolling brush trowel plate, and the gaps serve the function of discharging materials;

[0014] The flat trowel can be an internal corner trowel plate, and the connecting sleeve mechanism is a second sleeve. The internal corner trowel plate is communicated with the connecting pipe through the second sleeve;

[0015] The flat trowel can be an external corner trowel plate, and the connecting sleeve mechanism is a third sleeve. The external corner trowel plate is communicated with the connecting pipe through the third sleeve.

[0016] By adopting the above technical solutions, in terms of construction efficiency, the automatic grout discharging function enables the plastering process to eliminate the need for manual frequent shoveling of ash for replenishment, saving a large amount of time and physical strength. Construction workers can focus more on the plastering operation, accelerating the construction progress. The flow rate control mechanism precisely adjusts the mortar flow rate, enabling flexible adaptation to different plastering scenarios and further improving the construction efficiency. In terms of construction quality, the trowel effectively reduces the loss of mortar dropping, especially with obvious advantages in complex environments. At the same time, the water delivery pipe can timely spray water on the wall for moisturizing to ensure that the humidity of the wall is appropriate, solving the problem that it is difficult for traditional tools to ensure the uniformity of plastering quality. In addition, various types of multi-functional trowel plates and flat trowels adapted to different parts, such as internal corner trowel plates and external corner trowel plates, can meet various plastering requirements.

[0019] S2: Plastering operation: Pour the mortar into the mortar delivery handle, let it flow into the trowel cavity and flow out from the discharge port. When plastering ordinary walls, hold the integrated handle to keep the flat trowel at a suitable angle to the wall and push it evenly; when encountering a concave or convex corner, use the concave corner trowel or convex corner trowel, aim at the corresponding part to apply, and when using a rolling brush trowel, push the trowel while rolling the brush to brush the hair. During plastering, spray water through the water pipe to keep it moist according to the dryness of the wall.

[0020] In summary, the present invention mainly has the following beneficial effects: in terms of construction efficiency, the present invention uses the automatic slurry discharge function to eliminate the need for frequent manual shoveling of mortar and replenishing materials during the plastering process, thus saving a lot of time and physical strength. Construction personnel can focus more on plastering operations and speed up construction progress. The mortar flow rate can be accurately adjusted through the flow rate control mechanism, and it can flexibly adapt to different plastering scenes to further improve construction efficiency.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0037] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0038] Embodiment 1

[0039] A new type of multifunctional trowel with automatic grout discharging, as Figures 1-14As shown in the figure, the device is composed of an integrated handle 1, a flat trowel 2, a multi-functional trowel plate 3, a flow rate control mechanism 4, etc.;

[0040] The integrated handle 1 is composed of a mortar delivery grip 101, a connecting pipe 102, and a connector 103. It is made of high-strength plastic material through an injection molding process to ensure its structural strength and durability. The mortar delivery grip 101 is internally provided with a flow rate control mechanism 4 for adjusting the flow rate of the mortar;

[0041] The flow rate control mechanism 4 includes a regulating valve plate 401, a rotating shaft 402, a gear 403, a rack 404, a connecting plate 405, an adjusting slider 406, a movable shaft 407, an elastic piece 408, a locking tooth 409, and a card slot 410. The regulating valve plate 401 is rotatably connected to the mortar delivery grip 101 through the rotating shaft 402. A gear 403 is fixed on one side of the rotating shaft 402. The rack 404 meshes with the gear 403 and is slidably connected inside the mortar delivery grip 101. The connecting plate 405 is fixed at the end of the rack 404 and rotatably connects the adjusting slider 406 through the movable shaft 407. The adjusting slider 406 and the connecting plate 405 are elastically connected through the elastic piece 408. The other end of the bottom of the adjusting slider 406 is fixed with the locking tooth 409. Multiple groups of card slots 410 matching the locking tooth 409 are opened on the surface of the mortar delivery grip 101 to facilitate fixing the position of the adjusting slider 406, thereby adjusting the opening degree of the regulating valve plate 401 and achieving precise control of the mortar flow rate. A water delivery pipe 5 is fixed at the top of the mortar delivery grip 101, and the other end is connected to an external water supply tank to provide an appropriate amount of water for the plastering process to maintain the humidity of the wall;

[0042] The integrated handle 1 is connected to the flat trowel 2 through the connecting pipe 102 below. The flat trowel 2 is made of aluminum alloy material through a die-casting process and has good strength and thermal conductivity. A connecting sleeve mechanism 7 is arranged at the top of the flat trowel 2. The connecting sleeve mechanism 7 is divided into a first sleeve 701, a second sleeve 702, and a third sleeve 703 according to the type of the flat trowel 2;

[0043] When the flat trowel 2 is an ordinary flat trowel, the connecting sleeve mechanism 7 is the first sleeve 701. When the flat trowel 2 is an internal corner trowel 8, the connecting sleeve mechanism 7 is the second sleeve 702. When the flat trowel 2 is an external corner trowel 9, the connecting sleeve mechanism 7 is the third sleeve 703. The flat trowel 2 and the connecting pipe 102 are connected to each other through the corresponding sleeves and fixed with a locking part 6 to ensure a firm connection and prevent loosening during the plastering process;

[0044] The multi-functional trowel plate 3 is detachably connected to the bottom end inside the flat trowel 2. The multi-functional trowel plate 3 is designed in various types according to different plastering requirements. When uniform discharging is required, a round-hole discharging trowel plate 301 can be selected, and multiple groups of round discharging ports are opened at its bottom;

[0045] When strip-shaped discharging is required, a rectangular discharging trowel 302 can be selected, with multiple groups of rectangular discharging openings provided at the bottom;

[0046] When the wall surface needs to be brushed, a rolling brush trowel 303 can be selected. Multiple groups of rolling brushes 304 are rotatably connected to the bottom, and multiple groups of gaps 305 that cooperate with the rolling brushes 304 are provided at the bottom. The gaps 305 are used for discharging. The cavity provided inside the multifunctional trowel 3 is communicated with the slurry conveying grip 101 through a connecting pipe 102 to ensure that the mortar can be smoothly conveyed to the bottom of the trowel;

[0047] Preparation work

[0048] At the construction site, according to the specific requirements of the plastering project, select a suitable multifunctional trowel 3 and install it on the flat trowel 2. For example, for ordinary wall plastering, select the round-hole discharging trowel 301; for walls that require special textures, select the rectangular discharging trowel 302; for walls that need to be brushed, select the rolling brush trowel 303;

[0049] Connect the flat trowel 2 with the installed multifunctional trowel 3 to the connecting pipe 102 of the integrated handle 1 through the connecting sleeve mechanism 7, and fix it firmly with the locking member 6. Connect the water delivery pipe 5 to an external water supply tank to ensure normal water supply. According to the actual plastering requirements, set the flow rate of the mortar by adjusting the flow rate control mechanism 4. Push the adjusting slider 406 to disengage the locking teeth 409 from the current card slot 410, move the adjusting slider 406 to drive the connecting plate 405 and the rack 404 to move. The rack 404 drives the gear 403 to rotate, and then the regulating valve plate 401 rotates. After adjusting the flow rate, release the adjusting slider 406, and the elastic piece 408 makes the locking teeth 409 snap into the corresponding card slot 410 to fix the position of the regulating valve plate 401;

[0050] Specifically, the connecting head 103 is connected to an external mortar tank through a pipeline, and the mortar is conveyed to the inside of the slurry conveying grip 101 through a pipeline by a conveying booster pump. Furthermore, the flow rate and flow volume of the mortar can be controlled through the flow rate control mechanism 4. At the same time, one end of the water delivery pipe 5 is also connected to the output end of the booster pump located in the water tank, thereby playing a role in conveying water;

[0051] Plastering operation

[0052] Pour the mortar into the slurry conveying grip 101. The mortar enters the cavity of the multifunctional trowel 3 through the connecting pipe 102 and then flows out from the discharging openings at the bottom of the trowel. For ordinary wall plastering, hold the integrated handle 1, keep the flat trowel 2 at an appropriate angle with the wall surface, and evenly push the trowel to evenly apply the mortar on the wall surface. During the plastering process, according to the dryness of the wall surface, timely open the valve of the water delivery pipe 5 to spray an appropriate amount of water on the wall surface to keep the wall surface humidity appropriate, which helps to improve the plastering quality;

[0053] When encountering the inner corner or outer corner parts, replace the corresponding inner corner plastering plate 8 or outer corner plastering plate 9. For example, when dealing with the inner corner, connect the inner corner plastering plate 8 to the connecting pipe 102 through the second sleeve 702, then align the inner corner plastering plate 8 with the inner corner part, and push the trowel to evenly fill the inner corner with mortar, ensuring the plastering quality at the inner corner. When using the rolling brush plastering plate 303, while pushing the trowel, the rolling brush 304 will roll along with the movement of the trowel, which can not only apply mortar but also brush the wall surface, increasing the friction and aesthetics of the wall surface;

[0054] Cleaning and Maintenance

[0055] After the plastering work is completed, promptly clean up the remaining mortar to prevent the mortar from solidifying inside and on the surface of the trowel. Disassemble the multi-functional plastering plate 3, rinse the flat plastering plate 2, the multi-functional plastering plate 3 and the connecting pipe 102 with clean water to remove the residual mortar. Check whether the components of the flow rate control mechanism 4 are normal, and replace them in time if damaged. Regularly check the connection of the connecting sleeve mechanism 7 and the locking member 6 to ensure firm connection and prevent loosening during use.

[0056] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and do not limit the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
