Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a surface spraying device for building construction materials. Background Technology
[0002] During construction, some materials in the external space are exposed to wind, sun and rain for a long time, which can easily cause wear and corrosion. Therefore, protective coatings are applied to the surfaces of these materials.
[0003] According to a public notice (Announcement No.: CN220277373U) of a building construction material surface spraying device, the above application achieves lateral movement by setting a rotating motor of a lateral movement component in conjunction with moving wheels, and achieves longitudinal adjustment by setting a longitudinal movement component, thus realizing fully automatic spraying.
[0004] However, in actual use, the coating effect of the aforementioned equipment largely depends on the spraying efficiency of the nozzles. Since the spraying of building materials is not continuous, and materials need to be loaded and unloaded in batches, the spraying operation is intermittent. This can cause some coating to slightly solidify at the nozzles and spray outlets, which over time can clog the nozzles and affect the coating efficiency in subsequent operations. Therefore, we propose a surface spraying device for building materials. Utility Model Content
[0005] The purpose of this utility model is to provide a surface spraying device for building construction materials to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface spraying device for building construction materials, comprising a nozzle, a feed hose fixedly connected to the end of the nozzle, a mesh nozzle at the end of the nozzle away from the feed hose, a dividing module inside the nozzle, the dividing module including a mixing chamber inside the nozzle, a toothed ring rotatably mounted on the inner wall of the nozzle, a dividing mesh fixedly mounted on the inner surface of the toothed ring, a servo motor fixedly mounted on the top outer wall of the nozzle, a gear fixedly mounted on the output end of the servo motor, a conical rod fixedly mounted at the axis of the dividing mesh, three sets of swing grooves on the inner wall of the end of the conical rod away from the dividing mesh, a rotating rod rotatably mounted on the inner wall of the swing groove, a coil spring sleeved on the outer wall of the end of the rotating rod, a swing arm passing through and fixedly mounted on the rotating rod, a rotating block rotatably mounted on the inner wall of the end of the swing arm, and a turbulence ball fixedly connected to the side wall of the rotating block by a connecting rope.
[0007] Preferably, the toothed ring is T-shaped, and the inner wall of the nozzle has a T-shaped annular groove that matches the size of the toothed ring, and the toothed ring meshes with a gear.
[0008] Preferably, the swing groove is configured in an inverted V shape, and the bottom end of the swing groove near the dividing mesh is arc-shaped.
[0009] Preferably, the sidewall of the dividing mesh is fitted to the mesh nozzle, and the mesh diameter of the dividing mesh is larger than the nozzle diameter of the mesh nozzle.
[0010] Preferably, the inner wall of the end of the swing arm away from the rotating rod has a rotating hole adapted to the rotating block and the connecting rope, and the outer diameter of the rotating block is larger than the outer diameter of the connecting rope.
[0011] Preferably, an arc plate is fixedly installed on one side of the outer wall of the swing arm, and several pointed cones are fixedly installed on the spherical surface of the turbulence ball.
[0012] Preferably, the arc plate is located on the side away from the direction in which the swing arm rotates with the cone rod, and the arc-shaped protrusion of the arc plate is located towards the side of the feed hose.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation and transmission of various components of the segmentation module, the continuous rotation of the segmentation mesh during spraying cuts and pulls the solidified material that may appear at the mesh nozzle, preventing the mesh nozzle from becoming blocked. At the same time, the cone rod drives the three sets of swing rods to rotate, and with the arc plate set on one side of the swing rod, the swing rod is made to rotate around the rotating rod as the rotation center.

Detailed Implementation
[0021] 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.
[0022] Please see Figures 1-6 The diagram shows a surface spraying device for building construction materials, including a nozzle 1. A feed hose 2 is fixedly connected to the end of the nozzle 1, and a mesh nozzle 4 is opened at the end of the nozzle 1 away from the feed hose 2.
[0023] The end of the feed hose 2 is connected to the output end of an external delivery pump. The delivery pump continuously supplies feed hose 2 and nozzle 1, spraying the protective liquid for building materials outward through nozzle 1. At the same time, the mesh nozzle 4 contains several mesh holes. When the protective liquid is sprayed out from inside nozzle 1 under the pressure of the pump, it is atomized and sprayed out through mesh nozzle 4, improving the coating effect of the protective liquid on the surface of building materials.
[0024] The nozzle 1 has a dividing module inside, which includes a mixing chamber 3 inside the nozzle 1. A toothed ring 5 is rotatably mounted on the inner wall of the nozzle 1. A dividing mesh 6 is fixedly mounted on the inner surface of the toothed ring 5. A servo motor 7 is fixedly mounted on the top outer wall of the nozzle 1. A gear 8 is fixedly mounted on the output end of the servo motor 7. A conical rod 9 is fixedly mounted at the axis of the dividing mesh 6. Three sets of swing grooves 18 are opened on the inner wall of the end of the conical rod 9 away from the dividing mesh 6. A rotating rod 10 is rotatably mounted on the inner wall of the swing groove 18. A coil spring 12 is sleeved on the outer wall of the end of the rotating rod 10. A swing rod 11 is fixedly mounted through the rotating rod 10. A rotating block 14 is rotatably mounted on the inner wall of the end of the swing rod 11. A turbulence ball 16 is fixedly connected to the side wall of the rotating block 14 by a connecting rope 15.
[0025] Please see Figure 2 and Figure 3The servo motor 7 is positioned above the nozzle 1 to prevent the protective spraying liquid from falling onto the servo motor 7 and its output shaft during the spraying operation. At the same time, a protective cover is provided on the top of the nozzle 1 to protect the gear 8, preventing the gear 8 from being affected by impurities in the external environment at the meshing point of the gear ring 5 and thus preventing it from failing to transmit normally. Furthermore, the dividing mesh 6 contains several mesh holes, which ensure the passage of the protective spraying liquid in the mixing chamber 3, while also allowing the dividing mesh 6 to laterally cut and pull the solidified protective spraying liquid that may appear at the mesh nozzle 4 when it rotates, thus preventing it from becoming blocked.
[0026] In addition, three sets of swing grooves 18 are equipped with three sets of swing rods 11. When the cone rod 9 rotates with the dividing net 6, the three sets of swing rods 11 drive the turbulence ball 16 to rotate continuously in the mixing chamber 3, so as to promote the mixing of the flowing spray protective liquid and avoid the spray protective liquid from solidifying or clumping due to the long conveying pipeline, which would affect the spraying operation of the device.
[0027] The toothed ring 5 is T-shaped, and the inner wall of the nozzle 1 is provided with a T-shaped annular groove that matches the size of the toothed ring 5. The toothed ring 5 meshes with the gear 8.
[0028] The T-shaped setting of the toothed ring 5 ensures the sealing of the edge of the dividing screen 6, preventing the sprayed protective liquid from flowing out from the dividing screen 6 and the toothed ring 5, which would affect the spraying effect of the nozzle 1. Through the meshing transmission between the toothed ring 5 and the gear 8, the toothed ring 5 can drive the dividing screen 6 to rotate when the servo motor 7 is started.
[0029] The swing groove 18 is set in an inverted V shape, and the bottom end of the swing groove 18 near the dividing mesh 6 is set in an arc shape.
[0030] The inverted V-shaped arrangement of the swing groove 18 limits the deflection angle of the swing rod 11 within the swing groove 18, thereby preventing the disorderly rotation of the swing rod 11 from interfering with the movement of other swing rods 11 and the cone rod 9. In addition, the arc-shaped arrangement at the bottom of one side of the swing groove 18 reduces the resistance encountered by the sprayed protective liquid when it passes through this area, thereby preventing a large amount of sprayed protective liquid from entering the swing groove 18 and failing to be discharged in time.
[0031] The sidewall of the dividing mesh 6 is attached to the mesh nozzle 4, and the mesh diameter of the dividing mesh 6 is larger than the nozzle diameter of the mesh nozzle 4.
[0032] The dividing mesh 6 and the mesh nozzle 4 are closely fitted together, so that the mesh holes inside the continuously rotating dividing mesh 6 can pull and cut off any solidification or small lumps that may form at the mesh nozzle 4. In addition, the large diameter of the mesh holes of the dividing mesh 6 prevents it from completely blocking the sprayed protective liquid sprayed outward from the mixing chamber 3, thus avoiding affecting the spraying effect of the nozzle 1 from the mesh nozzle 4.
[0033] The inner wall of the end of the swing arm 11 away from the rotating rod 10 has a rotating hole that matches the rotating block 14 and the connecting rope 15. The outer diameter of the rotating block 14 is larger than the outer diameter of the connecting rope 15.
[0034] The rotating block 14 is rotatably installed in the rotating hole. The top of the connecting rope 15 is T-shaped with the rotating block 14 to ensure the installation stability of the connecting rope 15 at the bottom of the swing rod 11. The connecting rope 15 itself can also rotate to avoid the connecting rope 15 and the turbulence ball 16 from getting tangled and intertwined during actual use, which would affect the actual mixing effect of the device.
[0035] Please see Figure 4 and Figure 6 An arc plate 13 is fixedly installed on one side of the outer wall of the swing arm 11, and several pointed cones 17 are fixedly installed on the spherical surface of the turbulence ball 16.
[0036] The number of arc plates 13 is only set in one group, so that the center of gravity of the swing arm 11 is off the central axis. When it is continuously impacted by the sprayed protective liquid in the mixing chamber 3, it is not easy to maintain a high stability at a certain angle. Therefore, with the cooperation of the coil spring 12 and the rotating rod 10, the swing arm 11 will swing slightly at the end of the cone rod 9 while the cone rod 9 rotates, which promotes the mixing of the sprayed protective liquid in the mixing chamber 3.
[0037] The arc plate 13 is located on the side away from the swing arm 11 that rotates with the cone rod 9, and the arc-shaped protrusion of the arc plate 13 is located on the side facing the feed hose 2.
[0038] The placement of the arc plate 13 reduces the resistance of the swing rod 11 as it rotates with the cone rod 9. At the same time, the arc-shaped protrusion of the arc plate 13 faces the direction of the spray protective liquid, so that when the spray protective liquid impacts the arc plate 13, it can further cause the swing rod 11 to rotate around the rotating rod 10 as the rotation center. This, together with the turbulence ball 16, turbulences and mixes the spray protective liquid in the mixing chamber 3, reduces the generation of solids, and improves the spraying effect of the device.
[0039] Working principle: First, the external pumping equipment is started to pump the surface protective liquid for building materials into the mixing chamber 3 of the nozzle 1 through the feed hose 2. At the same time, the servo motor 7 is started, and with the transmission of the gear 8, the gear ring 5 drives the dividing mesh 6 to rotate. The dividing mesh 6, which is attached to the mesh nozzle 4, cuts and pulls away any solidified material that may appear at the mesh nozzle 4, preventing the mesh nozzle 4 from becoming blocked. Meanwhile, the cone rod 9 rotates synchronously with the dividing mesh 6, and with the arc plate 13 on one side of the swing rod 11, the swing rod 11 rotates around the rotating rod 10 as the rotation center. This, together with the turbulence ball 16 and the pointed cone 17, turbulence and mixes the protective liquid in the mixing chamber 3, reducing the generation of solidified material and improving the spraying effect of the device. Finally, the protective liquid is sprayed from the mesh nozzle 4 onto the surface of the building materials to protect them.
