Technical Field
[0001] This utility model relates to the field of spray device technology, specifically a construction dust suppression spray device. Background Technology
[0002] Construction dust suppression spraying is an environmentally friendly technology that controls dust by atomizing water and spraying it onto the construction area using specialized equipment. It utilizes a high-pressure system to convert water into micron-sized water mist, which comes into full contact with and adsorbs dust particles in the air, causing the dust to become heavier and settle, effectively reducing the concentration of pollutants such as PM10 and PM2.5. This technology is suitable for scenarios such as earthwork excavation, demolition operations, and material stockpiling, and can be implemented through fixed spray piles, mobile spray trucks, or tower crane spray systems. It is flexible in operation, water-saving and efficient, and some systems can even be linked to dust monitoring devices for automatic start and stop, making it an important means for construction sites to meet environmental protection requirements.
[0003] During construction, spray devices are needed to suppress dust. For example, a dust suppression spray device for construction, as disclosed in patent publication number CN119406175A, includes a base. An inner spray mechanism is fixedly connected to the upper surface of the base, an outer spray mechanism is fixedly connected to the top of the inner spray mechanism, and a synchronization adjustment mechanism is fixedly connected to the bottom of the outer spray mechanism. The inner spray mechanism includes a support, which is fixedly connected to the top of the base. The device sucks in dust and then sprays it to suppress dust, allowing the water mist to act precisely on the dust particles and improving the utilization rate of water resources.
[0004] However, when using the above-mentioned equipment, it can only rotate the sprayer and cannot adjust the spray range by adjusting the shape of the spray nozzle, making it difficult to control the spray range more accurately. Utility Model Content
[0005] The purpose of this invention is to provide a construction dust suppression spray device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A dust suppression spray device for construction includes a cylinder, a connecting base at the bottom of the cylinder, an installation plate inside the cylinder, a drive motor mounted on the installation plate, a fan blade mounted on the output shaft of the drive motor, a water supply pipe connected to the bottom of the cylinder, several circumferentially distributed connecting seats on the outer side of one end of the cylinder, several adjusting rods rotatably mounted on the connecting seats, elastic cloth on the inner side of the adjusting rods, and a fixing mechanism for fixing the adjusting rods on the outer side of the cylinder.
[0008] With the above structure, the elastic cloth is elastic and can be adjusted into different shapes, such as cylindrical, frustum-shaped, or fan-shaped nozzles, as the adjusting rod rotates. This allows for more precise adjustment of the spraying range. Furthermore, the adjusting rod can be fixed by a fixing structure to prevent it from shifting under wind force during operation. In use, water is supplied to the water supply pipe, and the drive motor drives the fan blades to rotate, dispersing and atomizing the water flow and spraying it out to achieve the effect of suppressing dust.
[0009] Preferably, the fixing mechanism includes a rotating ring rotatably sleeved on the outside of the cylinder, a limiting plate fixed on the rotating ring, and a plurality of circumferentially distributed clearance grooves on the limiting plate, a rotating disk rotatably mounted on the connecting seat, an adjusting rod fixed on the rotating disk, and a plurality of equally spaced limiting slots on the rotating disk.
[0010] With the above structure, when the clearance groove is aligned with the rotating disk, the rotating disk can rotate freely. After rotating to an appropriate angle, the limiting plate can be rotated by the rotating ring to separate the clearance groove from the rotating disk, so that the limiting plate is inserted into the corresponding limiting groove of the rotating disk, thereby fixing the rotating disk. Moreover, all rotating disks can be fixed at the same time, which is convenient to operate.
[0011] Preferably, the outer side of the rotating ring is provided with several circumferentially distributed handles.
[0012] With the above structure, the rotating ring can be rotated more conveniently via the handle.
[0013] Preferably, the elastic fabric consists of a connecting part and a deformable part. The end of the connecting part is fixedly connected to the end of the cylinder, and the inner edge of the connecting part is flush with the inner surface of the cylinder. The outer side of the deformable part is in contact with the adjusting rod.
[0014] With the above structure, the inner edge of the connecting part is flush with the inner surface of the cylinder, making the inner surface of the cylinder and the elastic cloth smoother overall, eliminating the steps that block the water mist spraying, which is beneficial for water mist spraying.
[0015] Preferably, a fixing sleeve is provided on the outer side of the end of the elastic fabric, and the fixing sleeve is sleeved on the end of the adjusting rod, and the connection position between the deformable part and the connecting part is fixed to the adjusting rod.
[0016] With the above structure, the end of the elastic cloth can be separated from the adjusting rod by removing the fixing sleeve. This way, the adjusting rod will not be subjected to the elastic force of the elastic cloth when it is rotated (it will not be subjected to the elastic force of the deformed part, and the connecting part is short, so the elastic force is small and negligible). It is more convenient for the operator to adjust the adjusting rod to the appropriate position. After all the adjusting rods are adjusted, the fixing sleeve can be put back on.
[0017] Preferably, a dustproof net is fixed to the end of the cylinder away from the elastic fabric.
[0018] With the above structure, when the fan blades rotate, the airflow passes through the dustproof net and enters the cylinder. At this time, the dustproof net can prevent debris such as leaves from entering, providing a certain degree of protection for the drive motor and fan blades.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] The elastic cloth and adjusting rod are used to adjust the spraying range. The elastic cloth is elastic and can be adjusted into different shapes as the adjusting rod is rotated. The adjusting rod can be fixed by a fixing structure to prevent it from shifting under the action of wind during operation.
[0021] Meanwhile, when the clearance groove is aligned with the rotating disk, the rotating disk can rotate freely. After rotating to an appropriate angle, the limiting plate can be rotated by the rotating ring to separate the clearance groove from the rotating disk, so that the limiting plate is inserted into the corresponding limiting groove of the rotating disk, thereby fixing the rotating disk. Moreover, all rotating disks can be fixed at the same time, which is convenient to operate. Attached Figure Description

Detailed Implementation
[0027] 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.
[0028] like Figures 1-4 As shown, this utility model provides a technical solution: a construction dust suppression spray device, including a cylinder 1, a connecting base 2 at the bottom of the cylinder 1, an installation plate 3 inside the cylinder 1, a drive motor 4 installed on the installation plate 3, a fan blade 5 installed on the output shaft of the drive motor 4, and a water supply pipe 6 connected to the bottom of the cylinder 1. A plurality of circumferentially distributed connecting seats 7 are provided on the outer side of one end of the cylinder 1, and a plurality of adjusting rods 8 are rotatably arranged on the connecting seats 7. An elastic cloth 9 is provided on the inner side of the adjusting rods 8, and a fixing mechanism for fixing the adjusting rods 8 is provided on the outer side of the cylinder 1.
[0029] It should be noted that the elastic cloth 9 is elastic, and as the adjusting rod 8 rotates, the elastic cloth 9 can be adjusted into different shapes, such as cylindrical, frustum-shaped, or fan-shaped nozzles, which allows for more precise adjustment of the spraying range. Moreover, the adjusting rod 8 can be fixed by a fixing structure to prevent it from shifting under the action of wind during operation. In use, water is input into the water supply pipe 6, and the drive motor 4 drives the fan blades 5 to rotate, dispersing and atomizing the water flow and spraying it out to achieve the effect of suppressing dust.
[0030] Reference Figure 4 As shown, the fixing mechanism includes a rotating ring 12 rotatably sleeved on the outside of the cylinder 1, a limiting piece 13 fixed on the rotating ring 12, and a plurality of circumferentially distributed clearance grooves 14 on the limiting piece 13, a rotating disk 10 rotatably mounted on the connecting seat 7, an adjusting rod 8 fixed on the rotating disk 10, and a plurality of equally spaced limiting slots 11 on the rotating disk 10.
[0031] It should be noted that when the clearance groove 14 is aligned with the rotating disk 10, the rotating disk 10 can rotate freely. After rotating to an appropriate angle, the limiting piece 13 can be rotated by the rotating ring 12 to separate the clearance groove 14 from the rotating disk 10, so that the limiting piece 13 is inserted into the corresponding limiting slot 11 of the rotating disk 10, thereby fixing the rotating disk 10. Moreover, all rotating disks 10 can be fixed at the same time, which is convenient to operate.
[0032] Reference Figure 4 As shown, the outer side of the rotating ring 12 is provided with several circumferentially distributed handles 15.
[0033] It should be noted that the rotating ring 12 can be rotated more conveniently through the handle 15.
[0034] Reference Figure 4 As shown, the elastic fabric 9 consists of a connecting part 901 and a deformable part 902. The end of the connecting part 901 is fixedly connected to the end of the cylinder 1, and the inner edge of the connecting part 901 is flush with the inner surface of the cylinder 1. The outer side of the deformable part 902 is in contact with the adjusting rod 8.
[0035] It should be noted that the inner edge of the connecting part 901 is flush with the inner surface of the cylinder 1, making the inner surface of the cylinder 1 and the elastic cloth 9 smoother overall, without any steps that would obstruct the water mist spraying, which is beneficial for water mist spraying.
[0036] Reference Figure 3 As shown, a fixing sleeve 16 is provided on the outer side of the end of the elastic fabric 9, and the fixing sleeve 16 is sleeved on the end of the adjusting rod 8, and the connection position of the deformable part 902 and the connecting part 901 is fixed to the adjusting rod 8.
[0037] It should be noted that removing the fixing sleeve 16 will separate the end of the elastic cloth 9 from the adjusting rod 8. This way, when rotating the adjusting rod 8, it will not be subject to the elastic force of the elastic cloth 9 (it will not be subject to the elastic force of the deformable part 902, and the connecting part 901 is short and the elastic force is small and negligible). This makes it easier for the operator to adjust the adjusting rod 8 to the appropriate position. After all the adjusting rods 8 are adjusted, the fixing sleeve 16 can be put back on.
[0038] Reference Figure 1 As shown, a dustproof net 17 is fixed to the end of the cylinder 1 away from the elastic cloth 9.
[0039] It should be noted that when the fan blade 5 rotates, the airflow will pass through the dustproof net 17 and enter the cylinder 1. At this time, the dustproof net 17 can prevent leaves and other debris from entering, and provide a certain degree of protection for the drive motor 4 and the fan blade 5.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
