Description

Technical Field

[0001] This utility model relates to the field of power trowel technology, specifically to a power trowel for highway construction. Background Technology

[0002] In highway construction and maintenance, the construction quality of concrete pavement directly affects the service life of the road and driving safety. Power trowels, as key equipment, play a vital role in improving the smoothness and evenness of the road surface. Traditional power troweling operations often generate large amounts of dust, which not only affects air quality and reduces visibility at the construction site but also poses a threat to the health of operators.

[0003] Existing power trowels typically suppress dust by directly spraying water. While this method reduces dust to some extent, its drawbacks are significant. Lacking effective water collection devices to recover excess water, the sprayed water easily seeps into the incompletely cured concrete, leading to reduced pavement strength or surface defects. This not only affects the final construction quality but may also require additional repair work, increasing construction costs and time. Furthermore, excessive moisture remaining in the construction area can negatively impact the site environment, such as increasing the risk of slipping. Utility Model Content

[0004] The purpose of this utility model is to provide a power trowel for highway construction, which solves the problem of serious dust flying during the construction process of traditional power trowels, and significantly improves the cleanliness of the working environment and construction efficiency.

[0005] To achieve the above objectives, a power trowel for highway construction is provided, including an engine, a support base at the bottom of the engine, a protective shell on the support base outside the engine, a power trowel blade at the bottom of the support base, a water tank on the protective shell, a water pump connected to one side of the water tank, and several sprinklers connected to the other end of the water pump above the power trowel blade. A circular water collection tray is provided below the sprinklers, the circular water collection tray includes a splash layer and a water collection layer located below the splash layer, and a drainage groove is provided between the splash layer and the water collection layer.

[0006] The splash guard is U-shaped and designed to guide moisture collection during the polishing process;

[0007] A water outlet pipe is installed at the bottom of the water collection layer, and a valve is installed on the water outlet pipe.

[0008] As a further improvement to this technical solution, a connecting pipe is provided at the other end of the water pump, and a coiled pipe is connected to the other end of the connecting pipe. Four inlet pipes are connected to the lower end of the coiled pipe, and a shower head is fixed at the bottom of each inlet pipe. The four shower heads are located above the corresponding positions around the polishing blade, and are used to spray water evenly onto the polishing blade to cool it and suppress dust.

[0009] As a further improvement to this technical solution, a fixed plate is fixedly connected to the bottom of the support base, and a protective cover is fixedly provided at the edge of the fixed plate. The protective cover is used to completely cover the polishing blade and the shower head located above it.

[0010] As a further improvement to this technical solution, four symmetrical connectors are fixedly provided around the bottom of the fixed plate. A protective block is fixedly connected to the bottom of the connector. The protective block is located on the outside of the polishing blade to prevent the worker's feet from directly contacting the polishing blade.

[0011] As a further improvement to this technical solution, the lower end of the fixed plate is fixedly connected to the ring-shaped water collection plate.

[0012] As a further improvement to this technical solution, a handle is provided on the protective shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This power trowel for highway construction is equipped with a circular water collection tray, which includes a splash ring and a water collection ring. The splash ring has a U-shaped cross-section and surrounds the trowel blades, effectively preventing sprayed water from splashing outwards and guiding it into the water collection ring. The water collection ring has a flat circular structure with a slightly inclined bottom, allowing the flowing water to naturally flow to a drain on one side or in the center, and excess water to be discharged through a water outlet pipe. This design ensures that water sprayed during dust removal does not seep into the incompletely cured concrete, avoiding problems such as reduced pavement strength or surface defects. Compared to traditional direct spraying methods, this invention significantly improves construction quality and reduces additional repair work caused by water seepage.

[0015] 2. In this highway construction power trowel, a protective cover is located at the edge of the fixed plate, completely covering the trowel blades and the sprinkler device above them. This effectively prevents external impurities from entering the work area during construction and also avoids accidental contact between operators and the rotating trowel blades, thus improving safety. Furthermore, four symmetrical connectors are located around the bottom of the fixed plate, with protective blocks fixedly attached to their bottom ends. These protective blocks are positioned on the outside of the trowel blades to further prevent direct contact between the worker's feet and the blades, reducing potential safety hazards.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Please see Figure 1 , Figure 2As shown, the purpose of this embodiment is to provide a power trowel for highway construction, including an engine 1, a support base 3 at the bottom of the engine 1, a protective shell 2 mounted on the support base 3, a fixing plate 5 at the bottom of the support base 3, and a protective cover 12 at the edge of the fixing plate 5, completely covering the trowel blade 9 and the sprinkler 14 above it, ensuring safety and cleanliness during construction. The protective cover 12 effectively prevents external impurities from entering the work area and also avoids accidental contact between the operator and the rotating trowel blade 9, thus improving safety.

[0027] like Figure 3 As shown, a water tank 16 is located on top of the protective shell 2 to store water. A water pump 17 is connected to one side of the water tank 16. Several spray nozzles 14 are connected to the other end of the water pump 17 above the trowel blade 9. These spray nozzles 14 are evenly distributed above corresponding areas around the trowel blade 9 to spray water during construction, thereby suppressing dust and cooling the trowel blade 9. This design not only improves the cleanliness of the construction environment but also extends the service life of the trowel blade 9.

[0028] like Figure 4 As shown, a circular water collection tray 6 is located below the shower head 14. The circular water collection tray 6 includes a splash layer 8 and a water collection layer 15 located below the splash layer 8, with a drainage groove 7 between them. The splash layer 8 is U-shaped and surrounds the trowel blade 9. Its unique design effectively prevents sprayed water from splashing outwards and guides the water into the water collection layer 15. This structure ensures that all sprayed water is effectively recovered, avoiding unnecessary impact on the construction site caused by water overflow.

[0029] like Figure 5 As shown, a water outlet pipe 21 is provided at the bottom of the water collection layer 15, and a valve 4 is installed on the water outlet pipe 21 to facilitate the drainage of water when there is excessive water in the water collection layer 15. This design takes into account the incompletely cured concrete surface. During construction, if too much water seeps into the uncured concrete, it may lead to a decrease in pavement strength or surface defects. Through the design of the water collection layer 15, water can be collected instead of seeping into the ground, thus avoiding these problems.

[0030] The design of the entire water collection system not only solves the shortcomings of traditional power trowels in dust control, but also significantly improves the cleanliness of the working environment and construction efficiency through effective water collection measures. In particular, it provides a practical solution for preventing excess water from damaging incompletely formed pavements. Through the application of this water collection system, this invention improves construction quality and efficiency while also greatly enhancing the safety and comfort of the working environment.

[0031] like Figure 2As shown, four symmetrical connectors 11 are fixed around the bottom of the fixed plate 5. Protective blocks 10 are fixedly connected to the bottom of the connectors 11. The protective blocks 10 are located on the outside of the trowel blade 9 to further prevent the worker's feet from directly contacting the trowel blade 9 and reduce potential safety hazards. These protective blocks 10 not only provide an additional safety barrier, but also make the operator feel more at ease when operating the trowel machine.

[0032] The protective shell 2 is equipped with a handle 13 at a moderate tilt angle, making it convenient for operators to operate the equipment and further enhancing the ease and safety of operation. This design not only improves the working conditions of construction workers and reduces the health effects of dust, but also prevents the risk of operators slipping due to wet ground.

[0033] In addition, the other end of the water pump 17 is equipped with a connecting pipe 18, and the other end of the connecting pipe 18 is connected to a coiled pipe 19. The lower end of the coiled pipe 19 is connected to four inlet pipes 20, and each inlet pipe 20 is fixedly equipped with a spray nozzle 14. The four spray nozzles 14 are located above corresponding positions around the trowel blade, and are used to evenly spray water onto the trowel blade 9 to cool it and suppress dust. This design not only solves the shortcomings of traditional trowel machines in dust control, but also significantly improves the cleanliness of the working environment and construction efficiency through effective water collection measures. It particularly emphasizes the protection of the incompletely formed road surface, ensuring construction quality and effect.

[0034] Through the synergistic effect of the aforementioned components, this invention not only improves construction quality and efficiency but also significantly enhances the safety and comfort of the working environment. This innovative design not only meets the environmental protection and efficiency requirements of modern highway construction but also provides operators with a safer and more convenient working experience.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
