Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying device for high-strength thin-film spraying materials. Background Technology

[0002] During coal mining, the sidewalls of coal mine roadways are affected by various factors such as water erosion and chemical corrosion, which can lead to reduced stability. Therefore, a series of protective measures are taken for the coal and rock walls of coal mine roadways during coal mining to ensure stability and safety.

[0003] Currently, the common method for treating coal and rock walls is to spray high-strength coating materials onto the coal and rock walls to form a sealed protective layer on the surface. This protective layer can isolate the coal and rock walls from water, chemical corrosion, and other factors in the roadway, thereby improving the anti-aging effect of the coal and rock walls, reducing the risk of coal and rock walls falling off, effectively preventing the weathering of coal and rock strata, and ensuring the safety of coal mine roadways.

[0004] Currently, the spraying materials used are in powder form. When using them, the materials need to be mixed with water to form a slurry, and then sprayed through a spraying device. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] Please refer to Figure 1-6 As a specific implementation method, the technical solution of this utility model is: a spraying device for high-strength thin-film spraying materials, comprising:

[0027] A base plate 1, a receiving cavity 2 disposed on the base plate 1, and a discharge pipe disposed at the bottom of the receiving cavity 2;

[0028] The stirring unit includes a stirring shaft 23 coaxially disposed in the receiving cavity and a stirring motor 24 for driving the stirring shaft 23 to rotate;

[0029] The mixing pipe 3 includes a mixing channel 31 and a discharge channel 32 that connects to the middle area of ​​the mixing channel 31. The discharge channel 32 is connected to the discharge pipe. One end of the mixing channel 31 is connected to a nozzle 5, and the other end is provided with a first quick connector 33.

[0030] Specifically, rollers 16 are installed at the four corners of the bottom surface of the base plate 1, and a handle 17 is installed at one end for easy movement. A receiving cavity 2 is provided above the base plate, and a discharge port 20 is provided at the bottom of the receiving cavity. The discharge port is connected to a mixing pipe 3 through a connecting pipe, and a manual control valve 30 is provided on the connecting pipe. (See reference) Figure 6 The mixing pipe 3 has an internal discharge channel 32, the upper end of which is connected to the discharge port 20. In use, a certain amount of powdered coating is weighed according to the mixing ratio, and then a certain proportion of water is added to the mixing chamber. The mixture is then stirred by the stirring shaft 23 to produce a slurry-like coating, making it more convenient to use. When the coating is contained in the receiving chamber 2, because the coating has a slurry structure, it can flow downwards along the discharge channel 32 under the action of gravity. Through the control valve 30, when the control valve is closed, the coating cannot flow downwards; when the control valve is open, it can flow downwards through the control valve. The mixing pipe also has a horizontally arranged mixing channel 31, the middle area of ​​which is connected to the lower end of the discharge channel 32. The first port 310 is connected to a first quick-connect fitting, which facilitates quick connection to a compressed air source. The second port 311 of the mixing channel 31 is connected to a nozzle 5. During operation, the control valve 30 is closed, and the mixed paint is placed into the receiving cavity 2. The first quick-connect fitting 33 is connected to the compressed air delivery pipe. The user holds the handle of the nozzle 5 and first supplies compressed air from the compressed air source. The compressed air enters the mixing channel 31 and then sprays out from the nozzle 5. Then, the control valve 30 is opened, and the paint in the receiving cavity 2 flows into the discharge channel 32 under the action of gravity, and then flows into the mixing channel. The paint flows with the airflow in the mixing channel and mixes in the mixing channel. Then, it flows into the nozzle 5 and flows out from the nozzle, achieving the spraying effect.

[0031] Specifically, an air compressor can be used as the compressed air source.

[0032] Furthermore, the nozzle 5 is a commonly used nozzle in the prior art. In specific use, an extension rod can be added to the end of the nozzle to adapt to spraying the top of the tunnel. As a specific implementation method, a second control valve 50 can also be installed on the nozzle 5.

[0033] Furthermore, as a preferred embodiment, the control valve 30 is selected from existing control valves capable of adjusting the opening degree, thereby adjusting the opening degree and thus adjusting the speed of spraying the coating.

[0034] Furthermore, as a preferred embodiment, the upper end of the receiving cavity 2 is detachably provided with a cover 22, and the stirring shaft 23 is rotatably disposed on the cover 22.

[0035] Furthermore, the cover 22 is also provided with a feed inlet 25. As a preferred embodiment, providing a feed inlet 25 on the cover 22 facilitates the addition of materials and improves ease of use. In a specific embodiment, a feed funnel can also be provided at the feed inlet for even easier material addition.

[0036] Furthermore, as a specific implementation method, refer to Figure 2 , Figure 3 , Figure 7 Both ends of the mixing channel 31 are connected to a first rigid pipe 12 and a second rigid pipe 13. The base plate 1 is provided with two fixing seats 14 corresponding to the first rigid pipe 12 and the second rigid pipe 13. The two fixing seats support and fix the ends of the first rigid pipe 12 and the second rigid pipe 13. The first quick connector 33 is connected to the end of the first rigid pipe 12.

[0037] Furthermore, the end of the second rigid tube 13 is connected to a second quick-connect fitting 131.

[0038] Specifically, both the first and second rigid pipes are metal-supported pipes. The specific structure of the fixing base 14 includes a support vertical rod 140 detachably fixed to the base plate 1, a lower support clamp 141 welded to the upper end of the support vertical rod, and an upper support clamp 142 detachably fixed to the lower support clamp via a screw. (See reference...) Figure 7 The end of the second rigid tube 13 is mounted on the lower support clamp 141, and then the upper support clamp is placed on the lower support clamp 141 and locked in place by a threaded rod. The upper support clamp 142 clamps and fixes the second rigid tube. In a specific embodiment, the end of the second rigid tube 13 is provided with a second quick connector 131. (Refer to...) Figure 1 The nozzle 5 is connected to a flexible high-pressure pipe 51, and the high-pressure pipe 51 is provided with a third quick connector 510 that can be quickly connected to the second quick connector; thereby facilitating the connection and disassembly of the nozzle and the second rigid pipe. As a specific implementation, both the first quick connector and the second quick connector can be male C-type quick connectors, and the third quick connector 510 can be a female C-type quick connector.

[0039] Furthermore, as a preferred embodiment, refer to Figure 6 The discharge channel 32 is located directly above the mixing channel, and the upper and lower ends of the discharge channel 32 are inclined towards the second rigid pipe 13. Specifically, this arrangement facilitates the flow of coating material into the mixing channel under gravity when the airflow passes rapidly through it.

[0040] Furthermore, as a specific embodiment, a support frame 4 is provided on the base plate 1, a first support ring 41 is horizontally provided at the upper end of the support frame 4, and a second support ring 26 is provided on the outer peripheral surface of the receiving cavity 2. The second support ring 26 is detachably connected to the first support ring 41.

[0041] Specifically, the second support ring 26 is fixedly connected to the outer wall of the receiving cavity 2. Multiple through holes are provided on the second support ring. Three support rod groups 42 are provided on the lower surface of the first support ring 41. One end of the support rod group is connected to the base plate 1, and the other end provides support force to the support ring. Multiple threaded holes corresponding to the through holes are provided on the first support ring 41. When the receiving cavity is placed inside the support ring, the second support ring 26 is supported by the first support ring 41. After the through holes and threaded holes are aligned, they are locked by locking screws. In this way, it is easy to install the receiving cavity 2 and the support is firm and reliable.

[0042] Further, refer to Figure 4 The specific structure of the support rod assembly includes: a plug-in guide rod 422 and a support tube 423. A fixing plate 424 is welded to the lower end of the support tube. The fixing plate is used for detachable and fixed connection with the base plate 1. Two through holes are drilled on the side wall of the support tube, and nuts are welded to the two through holes. Fixing bolts 425 are threaded onto the nuts. When the fixing bolts lock the plug-in rod 422, the plug-in rod cannot slide within the support tube. When loosened, the plug-in rod can slide freely. A lug 426 is provided at the upper end of the plug-in rod. The lug is hinged to a connecting plate 421 via a hinge shaft 427. The connecting plate 421 is welded to or detachably fixed to the first support ring. This arrangement allows for fine adjustment of the support height while supporting the cavity, facilitating the adjustment of the height of the first and second rigid tubes to match the height of the support base.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
