Description

Technical Field

[0001] This utility model mainly relates to the field of corundum floor construction technology, and in particular to a curing agent spraying device. Background Technology

[0002] Emery aggregate flooring (also known as emery abrasion resistant flooring) is a composite flooring formed by evenly spreading high-hardness emery aggregate (mainly composed of silicon carbide or metal oxides) onto the surface of concrete during its initial setting stage, followed by professional mechanical grinding and compaction. Emery aggregate flooring features high strength, wear resistance, a smooth and dense surface, and is economical and practical. Its high aggregate hardness (Mohs hardness above 9.2) significantly improves the floor's compressive strength, impact resistance, and wear resistance. Because the surface of emery aggregate flooring is non-porous after construction, it is less prone to dust and sand generation and is easy to clean. Compared to epoxy flooring, it is lower in cost and has a longer service life (up to 20 years or more), thus its widespread use is a significant advantage.

[0003] While emery aggregate flooring itself possesses excellent wear resistance, the concrete substrate still has inherent defects, thus requiring the use of a hardener. By applying a hardener (mostly silicate or lithium-based materials), it penetrates into the concrete, reacting chemically with free calcium to form calcium silicate gel. This gel fills the capillaries, significantly improving the substrate's density and impermeability, preventing the emery aggregate layer from detaching due to a loose substrate. The hardened substrate bonds more tightly to the emery aggregate layer, significantly enhancing its resistance to chemical corrosion (such as acids, alkalis, and salt spray) and freeze-thaw cycles, making it suitable for humid, temperature-sensitive, or corrosive environments. The hardener reaction forms a dense surface that, after polishing, achieves a marble-like shine, and daily cleaning requires only wiping with water, reducing maintenance costs.

[0004] In existing technologies, there is a lack of dedicated equipment for applying hardeners, typically requiring at least two workers to complete the work. Specifically, one worker sprays the hardener onto the ground with a spray bottle, while the other follows behind, using a mop to spread the hardener evenly. This method is time-consuming and labor-intensive, thus necessitating the design of a dedicated hardener application device to reduce manpower and improve efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a curing agent spraying device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A curing agent spraying device includes a wheeled carriage. A spray head for spraying curing agent onto the ground is fixed to the front of the carriage, and the spray head is connected to a reagent tank inside the carriage via a conduit. A coating component for evenly spreading the curing agent onto the ground is installed behind the spray head. This design integrates spraying and coating functions, changing the current method that requires two workers to operate separately, greatly reducing manpower requirements. The device is also easily movable and can operate continuously, effectively improving construction efficiency and meeting the needs of reducing manpower and increasing efficiency.

[0008] As a further improvement to the above technical solution:

[0009] The front top surface of the carriage has a chamfered angle to avoid obstructing the line of sight of operators at the rear of the carriage when observing the sprinkler heads. This design allows operators at the rear of the carriage to clearly see the working status of the sprinkler heads, making it easier to promptly detect problems such as clogging or uneven spraying, and thus make timely adjustments to ensure uniform spraying of the hardener, improve the curing effect of the floor, avoid floor quality defects caused by spraying problems, and reduce rework costs.

[0010] The top or side wall of the carriage has a viewing window for observing the amount of hardener remaining. Operators can visually know the amount of hardener remaining in the tank at any time, prepare to replenish the hardener in advance, prevent construction interruptions due to insufficient hardener, ensure construction continuity, and thus improve construction efficiency.

[0011] A handle is provided on the rear side of the carriage. This allows operators to easily grip and push the device, making operation more effortless and flexible, and enabling better control of the device's movement direction and speed. This ensures uniform application of the hardener and improves the quality of the ground curing process.

[0012] Several spray heads are arranged at horizontal intervals, with the spraying areas of adjacent spray heads partially overlapping. This layout increases the coverage area of ​​a single spray, reduces areas of repeated work, improves spraying efficiency, and ensures that all areas of the ground are evenly contacted with the hardener, thus improving the consistency of the overall curing effect of the ground.

[0013] The bottom of the reagent tank has an interface adapted to the conduit. This ensures a tight connection between the reagent tank and the conduit and facilitates easy installation. It also ensures that the curing agent can be stably delivered from the reagent tank to the spray head, avoiding leaks, blockages, or other issues that may affect the spraying operation, thus guaranteeing smooth spraying and improving work efficiency.

[0014] The coating component is configured as a horizontally arranged roller structure that adheres to the ground. As the roller structure rolls on the ground, it can evenly distribute the sprayed curing agent. Compared with manual mopping, this method is more efficient, uniform, and produces a more stable coating effect, effectively improving the quality of the curing agent coating on the ground and thus enhancing the overall quality of the ground.

[0015] The width L1 of the coating component is not less than the width L2 of the spraying area of ​​the spray head on the ground. This ensures that the spraying area of ​​the spray head can be covered in one coat, avoiding omissions, reducing repetitive work, improving work efficiency, and ensuring that the hardener is evenly applied to all parts of the ground, thus improving the uniformity of ground curing.

[0016] There are two coating components, one located at the front of the vehicle compartment and the other behind the operator. The front coating component applies a preliminary coating to the freshly sprayed hardener, while the rear coating component applies a second, finer coating, further improving the uniformity and effectiveness of the coating and enhancing the quality of the cured surface. The two coating components work together to accelerate the coating process and increase work efficiency. Furthermore, since the curing spraying device is manually pushed, and the operator is positioned between the two coating components, footprints are created during movement. The coating component located behind the operator effectively removes these footprints, thus improving the uniformity of the hardener on the ground.

[0017] The coating component located at the front is connected to the wheel via a transmission component; driven by the wheel, the coating component rolls along with the wheel. By utilizing the wheel's power to drive the coating component, no additional power source is required, simplifying the structure and improving energy efficiency. Simultaneously, synchronizing the rotation of the coating component with the movement of the device ensures continuous and uniform coating, improving work quality and efficiency.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1 to 3As shown, the curing agent spraying device of this embodiment includes a carriage 2 equipped with wheels 1. A spray head 3 for spraying curing agent onto the ground is fixed to the front side of the carriage 2. The spray head 3 is connected to a chemical tank 5 inside the carriage 2 via a conduit 4. A coating component 6 for evenly spreading the curing agent on the ground is also installed on the rear side of the spray head 3. The carriage 2 has a shell-like structure, with four wheels 1, which are respectively arranged at the four corners of the bottom of the carriage 2. A passageway 22 for the chemical tank 5 to enter and exit is opened on the top of the carriage 2. The chemical tank 5 is detachably fixed to the rear half of the carriage 2, and the space in the front half can be used for storage. To facilitate the entry and exit of materials, a door 23 is also provided on the side wall of the carriage 2. Inside the carriage 2, a support plate 24 is provided at the bottom. A sandwich space is formed between the support plate 24 and the bottom plate 25 of the carriage 2. The conduit 4 is arranged in the space, and the chemical tank 5 is fixed on the support plate 24. The conduit 4 is made of rigid material and is welded to the carriage 2 for fixation. The front end of the conduit 4 is connected to several spray heads 3, and its rear end extends upwards through the support plate 24. The bottom of the chemical tank 5 has an interface 51 adapted to the conduit 4 (this is existing technology and will not be described in detail here). The end of the conduit 4 extending out of the support plate 24 can mate with the interface 51, thereby guiding the hardener in the chemical tank 5 to the spray heads 3 for spraying onto the ground. To facilitate control of the hardener flow rate, a valve is also installed on the conduit 4; by adjusting the valve opening, the flow rate of the hardener can be adjusted accordingly.

[0025] Optionally, the front top surface of the carriage 2 is formed with a chamfer 21 to avoid obstructing the line of sight of operators at the rear of the carriage 2 when observing the spray head 3. The chamfer 21 forms an angle of 30° with the horizontal plane. Combined with the height of the carriage 2 and the distance by which the spray head 3 protrudes along the front of the carriage 2, this allows operators taller than 1.60 meters to easily observe the spraying of the spray head 3 from the rear of the carriage 2. Of course, in other embodiments, the setting of the chamfer 21 can be adjusted according to actual needs, and is not specifically limited here. In addition, the top surface or side wall of the carriage 2 is formed with a viewing window for observing the amount of curing agent, and a handle 7 is provided at the rear of the carriage 2.

[0026] In this embodiment, there are five spray heads 3, which are arranged at intervals along the horizontal direction, and the spraying areas of adjacent spray heads 3 partially overlap on the ground.

[0027] In this embodiment, there are two coating components 6, both arranged as horizontally oriented rollers, and both are in contact with the ground. One coating component 6 is located at the front of the carriage 2, and the other coating component 6 is located behind the operator. The width L1 of the coating component 6 is greater than the width L2 of the spraying area of ​​the spray head 3 on the ground. Furthermore, the coating component 6 located at the front is connected to the wheel 1 via a transmission component 8; driven by the wheel 1, the coating component 6 rolls along with the wheel 1. Specifically, the transmission component 8 is configured as a belt, which is simultaneously mounted on the axle of the coating component 6 and the axle of the wheel 1. When the wheel 1 rotates, the force is transmitted to the coating component 6 via the belt, thereby causing the coating component to rotate accordingly.

[0028] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
