Description

Technical Field

[0001] This utility model relates to the field of dust suppressant spraying, specifically a dust suppressant spraying device for road construction. Background Technology

[0002] Dust suppressants are composed of novel multifunctional high-molecular polymers. The cross-linked molecules in the polymer form a network structure, and there are various ionic groups between the molecules. Due to the high charge density, they generate a strong affinity with ions and can quickly capture and firmly adsorb particulate dust through coagulation, adhesion and other effects. After drying, they can solidify into a film on the dust surface, thus having a strong dust suppression and dust prevention effect.

[0003] In the existing technology, when repairing a road due to severe cracking, the hardened pavement of the cracked section needs to be excavated to expose the soil layer, and then repaired according to the construction schedule. However, after excavation, the exposed soil layer will cause dust, so dust suppressant needs to be sprayed before construction.

[0004] In the existing technology, dust suppressants are generally stored in water trucks and sprayed through spraying devices installed at the end of the trucks. However, this method requires vehicles to pass through exposed road surfaces. Due to the difference in elevation between the excavation site and the hardened road surface, the vehicles will experience bumps. Furthermore, when the vehicles travel to the excavation site, they will stir up dust. Utility Model Content

[0005] The purpose of this utility model is to provide a dust suppressant spraying device for road construction in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust suppressant spraying device for road construction, comprising a connecting frame, a strip groove on the lower horizontal plate of the connecting frame, a rotary drive mechanism mounted on the upper horizontal plate of the connecting frame, an input water pipe fixedly connected to the output end of the rotary drive mechanism, the input water pipe being rotatably connected to the upper horizontal plate of the connecting frame, an output water pipe fixedly connected to the output end of the input water pipe, a support mechanism extending to the outside of the output water pipe being rotatably mounted on the lower horizontal plate of the connecting frame, and multiple nozzles being equidistantly mounted below the outer periphery of the output water pipe.

[0007] As a further embodiment of this utility model: the rotary drive mechanism includes a forward and reverse motor and a worm gear mounted on the upper horizontal plate of the connecting frame. The output end of the forward and reverse motor is fixedly mounted with a drive pulley, and one end of the worm gear is mounted with a driven pulley. The drive pulley and the driven pulley are connected by belt drive. A worm wheel meshes with the outer periphery of the worm gear, and the worm wheel is interference-fitted to the outer periphery of the input water pipe.

[0008] As a further embodiment of this utility model: the support mechanism includes a rotating column rotatably mounted on the top of the lower horizontal plate of the connecting frame. A support ring is integrally formed on the top of the rotating column. Horizontal bars are fixedly installed at equal intervals around the end of the support ring. An end cap is provided at the end of the connecting frame away from the rotating column. The end cap is sleeved on the outer wall of the three horizontal bars. An external thread is formed at the end of the horizontal bar near the end cap. A nut is connected to the horizontal bar through the external thread.

[0009] As a further embodiment of this utility model: a fixed water pipe is rotatably installed at the top of the input water pipe, the upper horizontal plate of the connecting frame is fixedly connected to the fixed water pipe by a bracket, and a sealing ring is installed at the rotatable connection between the input water pipe and the fixed water pipe.

[0010] As a further improvement of this utility model, the nozzle and the strip groove are aligned vertically.

[0011] As a further improvement of this utility model, the outer wall of the output water pipe is integrally formed with a fixing ring that is sleeved with the crossbar.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting a rotary drive mechanism, the output water pipe can be rotated 180 degrees, so that the output water pipe is misaligned with the towing vehicle (such as a water truck). That is, the towing vehicle travels on the hardened road surface, while the output water pipe is located above the excavated road surface. Spraying in this way can avoid the problem of dust being stirred up by the vehicle traveling on the excavated road surface. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-5 In this embodiment of the utility model, a dust suppressant spraying device for road construction includes a connecting frame 1. A strip groove 2 is provided on the lower horizontal plate of the connecting frame 1. A rotary drive mechanism is installed on the upper horizontal plate of the connecting frame 1. An input water pipe 6 is fixedly connected to the output end of the rotary drive mechanism. The input water pipe 6 is rotatably connected to the upper horizontal plate of the connecting frame 1. An output water pipe 4 is fixedly connected to the output end of the input water pipe 6. A support mechanism extending to the outside of the output water pipe 4 is rotatably installed on the lower horizontal plate of the connecting frame 1. Multiple nozzles 5 are equidistantly installed below the outer periphery of the output water pipe 4. The nozzles 5 and the strip groove 2 are aligned vertically.

[0022] In this embodiment: First, the device is installed on the end of the frame of the tractor vehicle using mounting components (such as bolts). When the road is being constructed, such as after partial excavation of the road and exposure of the soil base at the excavated road location, the rotating drive mechanism is moved. The rotating drive mechanism drives the input water pipe 6 to rotate 180 degrees. The input water pipe 6 drives the output water pipe 4 to rotate 180 degrees simultaneously. At this time, the input water pipe 6 is located above the excavated location, so that the tractor vehicle can travel on the hardened road while the input water pipe 6 is located at the excavated road location. Afterwards, the tractor vehicle can drive the input water pipe 6 to spray dust suppressant at the excavated location.

[0023] Please refer to this carefully. Figure 4 and Figure 5 The rotary drive mechanism includes a forward and reverse motor 9 and a worm gear 11 mounted on the upper horizontal plate of the connecting frame 1. The output end of the forward and reverse motor 9 is fixedly mounted with a drive pulley 10, and one end of the worm gear 11 is mounted with a driven pulley 18. The drive pulley 10 and the driven pulley 18 are connected by a belt 17. A worm wheel 7 meshes with the outer periphery of the worm gear 11, and the worm wheel 7 is interference-fitted to the outer periphery of the input water pipe 6.

[0024] In this embodiment: by starting the forward and reverse motor 9, the forward and reverse motor 9 drives the active belt pulley 10 to rotate synchronously. The rotating active belt pulley 10 drives the driven belt pulley 18 to rotate through the belt 17. The driven belt pulley 18 can drive the worm gear 11 to rotate. The rotating worm gear 11 can squeeze the tooth block outside the worm wheel 7 through its external helical part, so as to realize the rotation of the worm wheel 7. The rotating worm wheel 7 can realize the rotation of the input water pipe 6.

[0025] This design allows the drive rotation mechanism to be located entirely at the top of the upper horizontal plate of the connecting frame 1. The design of the worm gear 7 and worm 11 can prevent the output water pipe 4 from rotating during the movement of the traction vehicle.

[0026] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The support mechanism includes a rotating column 3 rotatably mounted on the top of the lower horizontal plate of the connecting frame 1. A support ring 12 is integrally formed on the top of the rotating column 3. Horizontal bars 14 are fixedly installed circumferentially at equal intervals at the ends of the support ring 12. An end cap 16 is provided at the end of the connecting frame 1 away from the rotating column 3. The end cap 16 is sleeved on the outer wall of the three horizontal bars 14. The end of the horizontal bar 14 near the end cap 16 is formed with an external thread. Nuts 15 are connected to the horizontal bars 14 through the external thread. A fixing ring 13 is integrally formed on the outer wall of the output water pipe 4 and sleeved with the horizontal bars 14.

[0027] In this embodiment: when the water is sprayed outward through the output water pipe 4, its overall weight increases. At this time, the support mechanism can provide effective support for the output water pipe 4, thus avoiding the problem of deformation of the output water pipe 4.

[0028] The weight of the output water pipe 4 is transferred to the support ring 12 through the fixed ring 13 and the crossbar 14, and finally to the rotating column 3, thus ensuring the stability of the output water pipe 4.

[0029] During installation, one end of the crossbar 14 is passed through the fixing ring 13 and finally welded to the support ring 12. After welding, the end cap 16 is fitted onto the outer wall of the crossbar 14, and then the end cap 16 is fixed by tightening the nut 15.

[0030] Please refer to this carefully. Figure 5 A fixed water pipe 8 is rotatably installed at the top of the input water pipe 6. The upper horizontal plate of the connecting frame 1 is fixedly connected to the fixed water pipe 8 through a bracket. A sealing ring is installed at the rotatable connection between the input water pipe 6 and the fixed water pipe 8.

[0031] In this embodiment: when the inlet water pipe 6 rotates, the inlet water pipe 6 and the fixed water pipe 8 rotate relative to each other, and a sealing ring is installed at the rotating part to prevent water leakage at the rotating connection.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
