Description

Technical Field

[0001] The utility model relates to the field of building construction equipment, in particular to a dust reduction device at a construction site. Background Art

[0002] Whether it is construction or other construction processes that can generate dust, dust suppression equipment is an indispensable auxiliary equipment.

[0003] Among them, the most widely used dust reduction equipment is the fog cannon, which uses a high-pressure pump and atomizing nozzle based on the wind conveying principle to atomize water into fine water mist, and then uses the rotation of the fan to generate airflow to send the atomized water mist to a longer distance. When the water mist reaches a longer distance, it adheres to the dust in the air, and the dust in the air condenses into clumps, and finally falls to the ground under the action of gravity, thereby achieving the purpose of dust removal.

[0004] When the existing fog cannon is not in operation, its atomizing nozzle is exposed to the external environment for a long time. Due to the small nozzle diameter of the atomizing nozzle, its long-term exposure to the external environment can easily allow impurities (dust particles) in the external environment to enter the interior, causing the atomizing nozzle to be blocked. On the other hand, the atomizing nozzle exposed to the air for a long time is also prone to rust.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] In view of the above-mentioned defects, the purpose of the utility model is to provide a dust reduction device for construction sites, which can drive the atomizing nozzle to the containing bin for protection through a driving member in a non-working state, thereby reducing the negative impact of the external environment on the atomizing nozzle and further increasing the service life of the equipment.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a construction site dust reduction device, including a barrel; an atomizing nozzle and a accommodating chamber arranged on the side wall of the barrel and used to accommodate the atomizing nozzle are arranged at the end of the barrel; the atomizing nozzle is driven by a driving member and placed in the accommodating chamber in a rotating manner; a reset member for driving the atomizing nozzle to reset is installed at the rotating connection of the atomizing nozzle, and after the atomizing nozzle loses the drive of the driving member, it is further driven by the reset member to enter the initial state.

[0008] According to the construction site dust suppression device of the utility model, the atomizing nozzle is connected to a hose; the end of the hose is connected to the water supply channel.

[0009] According to the construction site dust suppression device of the utility model, the reset member is a torsion spring; one end of the torsion spring is connected to the atomizing nozzle, and the other end is connected to the end side wall of the barrel.

[0019] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] See also Figure 1 , Figure 2 and Figure 4 The utility model provides a construction site dust reduction device, which includes a barrel 1, which is mounted on a base, and a driving structure (which is an existing structure and is not the innovation of this application) for driving the barrel 1 to swing at an angle can be set on the base to increase the working range of the fog cannon. The end of the barrel 1 is provided with an atomizing nozzle 2 and a storage bin arranged on the side wall of the barrel 1 and used to accommodate the atomizing nozzle 2. The number of the atomizing nozzle 2 is at least one, and the number and position of the storage bins correspond one-to-one with the atomizing nozzle 2 (each atomizing nozzle 2 corresponds to a storage bin). Specifically in the present embodiment, a plurality of atomizing nozzles 2 and storage bins are arranged at the end of the barrel 1 in an equidistant ring.

[0021] When the fog cannon is in a non-working state, the atomizing nozzle 2 is driven by a driving member 3 and is placed in a accommodating chamber in a rotating manner. By storing the atomizing nozzle 2 in the accommodating chamber, the contact between the atomizing nozzle 2 and the outside air is reduced, and impurities or sulfide substances in the outside air are reduced from entering the nozzle, thereby protecting the atomizing nozzle 2 and further increasing the service life of the equipment.

[0022] The atomizing nozzle 2 is connected to a hose; the end of the hose is connected to the water supply channel, and the hose provides a flexible connection to ensure that the water supply of the atomizing nozzle 2 is not affected after the angle is switched.

[0023] See also Figure 2 and Figure 3, the rotating connection of the atomizing nozzle 2 is equipped with a reset member that drives it to reset. When the equipment is in working state (starting atomization work), after the atomizing nozzle 2 loses the drive of the driving member 3, it is further driven by the reset member to enter the initial state. The axis of the atomizing nozzle 2 in the initial state is at a predetermined angle with the axis of the fog cannon (as shown in the figure, the axis of the atomizing nozzle 2 is 30° to 45° with the axis of the fog cannon). Specifically in this embodiment, in order to better drive the state switching of multiple atomizing nozzles 2, the present application adopts the following structure, the driving member 3 is an annular structure that is sleeved on the end of the barrel 1 and moves relative to its axial direction, the end of the atomizing nozzle 2 is provided with a convex block 21 that cooperates with the driving member 3 (the convex block 21 is provided on the other side of the rotating connection point relative to the atomizing nozzle 2), and the shape of the convex block 21 can be adjusted as needed; the moving driving member 3 drives the atomizing nozzle 2 to rotate by squeezing the convex block 21, and the rotating atomizing nozzle 2 enters the accommodating bin after rotation. Similarly, after the atomizing nozzle 2 is squeezed, the atomizing nozzle 2 is driven by the reset member to enter the initial state. Through the above structure, the annular drive member 3 can synchronously drive multiple atomizing nozzles 2 to rotate.

[0024] In addition, the reset member is a torsion spring; one end of the torsion spring is connected to the atomizing nozzle 2, and the other end is connected to the end side wall of the barrel 1.

[0025] Preferably, the end of the barrel 1 of the utility model is sleeved with a closed ring 7 for closing the port of the storage bin 4, and a plurality of closed baffles may be provided on the closed ring 7; after the atomizing nozzle 2 is transferred into the storage bin at the end of the barrel 1, the closed ring 7 closes the port, further increasing the protective effect of the storage bin on the atomizing nozzle 2. Of course, the closed structure is not limited to the above structure, and may also be a rubber baffle provided at the port position of the storage bin. The closed ring 7 is rotated forward or reversely by a predetermined angle to open or close the port of the storage bin.

[0026] Since the closed ring 7 is arranged on the inner wall of the atomizing nozzle 2, it is not convenient to rotate. Therefore, the present application has made the following improvements: a first lever 71 is arranged at the end of the closed ring 7; a second lever 72 is arranged at the end of the driving member 3 (specifically, in the present embodiment, two second levers 72 are arranged); after the driving member 3 moves to drive the atomizing nozzle 2 to enter the storage bin, the driving member 3 is rotated, and the closed ring 7 is driven to rotate under the cooperation of the first lever 71 and the second lever 72 (when working, the first lever 71 is inserted into the area between the two second levers 72), so as to achieve the blocking of the storage bin opening. Similarly, after the closed ring 7 is driven to rotate in the opposite direction, the storage bin opening is opened.

[0027] In summary, the utility model provides a construction site dust reduction device, including a barrel, which is mounted on a base, and a driving structure that drives the barrel to swing at an angle can be arranged on the base to increase the working range of the fog cannon. The end of the barrel is provided with an atomizing nozzle and a storage bin arranged on the side wall of the barrel and used to accommodate the atomizing nozzle. The number of the atomizing nozzle is at least one, and the number and position of the storage bins correspond to the atomizing nozzles one by one (each atomizing nozzle corresponds to a storage bin). A plurality of atomizing nozzles and storage bins are arranged in an equidistant ring at the end of the barrel. When the fog cannon is in a non-working state, the atomizing nozzle is driven by a driving member to be placed in the storage bin in a rotating manner. By storing the atomizing nozzle in the storage bin, the contact between the atomizing nozzle and the outside air is reduced, and impurities or sulfides in the outside air are reduced from entering the nozzle, which plays a protective role on the atomizing nozzle and further increases the service life of the equipment. The utility model drives the atomizing nozzle to rotate into the containing bin for protection through the driving member in a non-working state, thereby reducing the negative impact of the external environment on the atomizing nozzle and further increasing the service life of the equipment.

[0028] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
