Description

Technical Field

[0001] This utility model relates to the field of construction engineering, and in particular to a spraying device for construction engineering. Background Technology

[0002] Construction spraying equipment is a type of device used for spraying operations on construction sites. Spraying is frequently required in the construction of buildings, bridges, roads, and ships to protect surfaces, prevent corrosion, and improve appearance. Traditional spraying operations typically require significant manpower and time, are inefficient, and can easily cause environmental pollution and safety hazards.

[0003] Currently, construction spraying devices use nozzles to evenly spray paint onto the construction surface. However, when large-area spraying is required, the spray gun is slow and cannot adjust the spraying range according to the specific work situation to adapt to different working environments. Secondly, spraying devices are often connected to material tanks, which are heavy when full of paint and extremely difficult to move. Even when loaded with a trolley, they may still tip over when passing over uneven surfaces. Therefore, a construction spraying device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a spraying device for construction projects, which aims to improve the existing technology by addressing the problem that the spraying range cannot be adjusted to improve spraying efficiency and that the material bucket is prone to tipping over when passing through uneven road surfaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spraying device for construction engineering, comprising a base plate, four sets of universal wheels at the bottom end of the base plate, a push rod fixedly connected to the outer wall of the base plate, a high-pressure pump fixedly connected to the upper outer wall of the base plate, a water pipe inside the high-pressure pump, a nozzle fixedly connected to the end of the water pipe, two sets of baffles slidably connected to the inner wall of the nozzle, and a buckle assembly elastically connected to the inner wall of the baffles by a return spring.

[0006] As a further description of the above technical solution:

[0007] A circular groove is formed on the outer wall of the base plate, and a sliding groove is formed on the outer wall of the base plate. A clamping block is slidably connected to the inner wall of the sliding groove. Two sets of brackets are hinged to the inner end of the bottom of the clamping block. A threaded sleeve is hinged to the inner end of each set of brackets. A threaded rod is rotatably connected to the inner wall of the base plate.

[0008] As a further description of the above technical solution:

[0009] The latching assembly includes a limiting block, and a limiting groove is formed on the inner wall of the nozzle.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the threaded rod is threadedly connected to the inner wall of the threaded sleeve.

[0012] As a further description of the above technical solution:

[0013] The lower outer wall of the clamping block is slidably connected to the upper outer wall of the base plate.

[0014] As a further description of the above technical solution:

[0015] One end of the reset spring is fixedly connected to the inner end of the limiting block, and the other end of the reset spring is fixedly connected to the inner wall of the baffle.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the limiting block is engaged with the inner wall of the limiting groove.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by setting a threaded rod, when fixing the material bucket, turning the knob causes the threaded rod to rotate, thereby causing the bracket angle to shift and pull the clamping block closer to the center to clamp the material bucket and prevent it from tipping over on uneven roads.

[0020] 2. In this utility model, by setting a limiting block and a baffle, when it is necessary to adjust the spraying area of ​​the nozzle, press the limiting block inward and then move the baffle to move it towards the center to cover the hole of the nozzle, thereby adjusting its coverage area.

[0026] 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.

[0027] Reference Figures 1-2 This utility model provides an embodiment of a spraying device for construction engineering, including a base plate 1. Four sets of casters 3 are provided at the bottom of the base plate 1 to facilitate movement of the material bucket while locking the casters 3 for greater stability during placement. A push rod 2 is fixedly connected to the outer wall of the base plate 1, allowing the device to be moved to a designated position via the push rod 2. A circular groove 4 is formed on the upper outer wall of the base plate 1 for placing the material bucket. A sliding groove 6 is formed on the outer wall of the base plate 1, with a clamping block 5 slidably connected to the inner wall of the sliding groove 6. The lower outer wall of the clamping block 5 is slidably connected to the upper outer wall of the base plate 1. After the material bucket is placed on the circular groove 4, the clamping block 5 is controlled to move the material bucket. To ensure stability and prevent easy tipping, the clamping block 5 is fixed in place. Two sets of brackets 7 are hinged to the inner end of the bottom of the clamping block 5. Each set of brackets 7 is hinged to a threaded sleeve 8 at the inner end. The inner wall of the threaded sleeve 8 is set with reverse threads. A threaded rod 9 is rotatably connected to the inner wall of the base plate 1. A knob is set at the outer end of the threaded rod 9. Rotating the knob can drive the threaded rod 9 to rotate. The outer wall of the threaded rod 9 is threadedly connected to the inner wall of the threaded sleeve 8. The rotation of the threaded rod 9 causes the two sets of threaded sleeves 8 connected to it to move closer or separate, causing the brackets 7 to change angle, thereby pulling the clamping block 5 to move closer or separate along the slide groove 6, thus fixing or loosening the material bucket.

[0028] Reference Figure 1 and Figure 3A high-pressure pump 10 is fixedly connected to the outer wall above the base plate 1. A water pipe 11 is installed inside the high-pressure pump 10, and a nozzle 12 is fixedly connected to the end of the water pipe 11. The water pipe 11 is connected to a material tank. The high-pressure pump 10 extracts the paint from the material tank and applies it through the nozzle 12. Two sets of baffles 13 are slidably connected to the inner wall of the nozzle 12. The two sets of baffles 13 can slide towards the center to block some of the holes in the nozzle 12, thereby controlling the spraying area. A snap-fit ​​assembly is elastically connected to the inner wall of the baffles 13 via a return spring 14. The snap-fit ​​assembly includes a limiting block 15, with one end of the return spring 14 close to the inner side of the limiting block 15. One end is fixedly connected, and the other end of the return spring 14 is fixedly connected to the inner wall of the baffle 13. Pressing the limiting block 15 inward can cause it to press the return spring 14 into the groove of the baffle 13. At the same time, the elastic force generated by the deformation of the return spring 14 gives the limiting block 15 an outward pushing force, causing it to reset. The inner wall of the nozzle 12 has a limiting groove 16. The outer wall of the limiting block 15 is engaged with the inner wall of the limiting groove 16. When the limiting block 15 is pressed into the groove of the baffle 13, it is disengaged from the limiting groove 16. At this time, the baffle 13 can be moved to slide along the inner wall of the nozzle 12 to block the hole and control the spraying range of the device.

[0029] Working principle: Place the mixed raw material bucket in the circular groove 4 above the base plate 1. Turn the knob to rotate the threaded rod 9, causing the two sets of threaded sleeves 8 to separate, thereby changing the angle of the bracket 7. This pulls the two sets of clamping blocks 5 together, clamping the outer wall of the bucket and fixing it to the base plate 1. This facilitates transportation and increases stability, preventing the bucket from tipping over on uneven surfaces. Then, connect the water pipe 11 to the bucket and start the high-pressure pump 10 to extract the raw material from the bucket. Spray the material through the nozzle 12. When the spraying range of the nozzle 12 needs to be adjusted according to specific requirements, press the limiting block 15 inward until it is disengaged from the limiting groove 16. At this time, the baffle 13 can be slid to block part of the nozzle 12 holes to adjust the coverage area. After adjustment, release the limiting block 15, and the return spring 14 pushes it into the limiting groove 16 for fixation.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
