Description

Technical Field

[0001] The utility model relates to the technical field of construction spraying, in particular to a construction spraying dust reduction device. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. During the construction process, fences will be used to isolate the construction site. At the same time, a large amount of dust will be generated at the construction site, causing environmental pollution and endangering the health of construction workers.

[0003] In order to prevent dust from affecting the environment outside the construction site, at present, the treatment of dust on construction sites is mostly done by spraying water to settle the dust. Most of the existing construction sites will install nozzles on the fences to spray and reduce dust. However, most of the existing nozzles are fixed nozzles, resulting in a limited spraying range, which affects the efficiency of spraying and dust reduction.

[0004] To this end, we propose a construction spray dust reduction device. Utility Model Content

[0005] The utility model aims to provide a construction spray dust reduction device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction spray dust reduction device, comprising a plug plate, a slide rail, a support column and a connecting plate, the top surface of the plug plate is symmetrically fixedly connected with the slide rail, the support column is slidably installed inside the slide rail, and the connecting plate is rotatably installed on the side of the top end of the support column.

[0007] Preferably, a slot is provided at the bottom end of the plug plate, a push rod motor is symmetrically installed on the top surface of the plug plate located inside the slide rail, a connecting rod is installed at the output end of the push rod motor, and the other end of the connecting rod is fixedly connected to the support column.

[0008] Preferably, a partition is fixedly connected to the front end surface between the support columns, and a water collecting box is fixedly connected to the surface of the partition.

[0009] Preferably, a mounting plate is fixedly connected to the back surface of the top end of the support column, a rotating gear is installed on the surface of the connecting plate, an arc gear is rotatably installed on the surface of the mounting plate, and the rotating gear is meshingly connected with the arc gear, a first rotating motor is installed on the back surface of the mounting plate, and the output end of the first rotating motor is fixedly connected to the arc gear.

[0010] Preferably, a mounting platform is fixedly connected between the connecting plates, a water diversion pipe is installed between the connecting plates, a rotating nozzle is rotatably installed on the front end surface of the mounting platform, a branch pipe is fixedly connected to the outer surface of the water diversion pipe, and the other end of the branch pipe is connected to the rotating nozzle.

[0011] Preferably, a driven gear is sequentially installed on the front end surface of the mounting platform, and the driven gear is fixedly connected to the rotating nozzle, a crawler is meshingly installed on the outer surface of the driven gear, a driving gear is rotatably installed on the surface of one end of the mounting platform, and the driving gear is transmission-connected to the driven gear through the crawler, a second rotating motor is installed on the back of the mounting platform, and the output end of the second rotating motor is fixedly connected to the driving gear.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: through the cooperation of the rotating gear and the arc gear installed on the side of the connecting plate, when the first rotating motor runs, it drives the arc gear to rotate. Since the arc gear is meshed and connected with the rotating gear, the rotation of the arc gear drives the rotating gear to rotate, thereby driving one end of the connecting plate to lift upward. At the same time, since the arc gear contacts the rotating gear at the untoothed part, the rotating gear loses the meshing transmission power, and one end of the connecting plate is restored to its original position to realize that the connecting plate repeatedly drives the rotating nozzle to swing up and down, thereby increasing the spraying area and improving the dust reduction effect. Through the cooperation of the driven gear and the driving gear installed on the back of the rotating nozzle, when the first rotating motor runs, it drives the driving gear to rotate, and the driven gear rotates together with the driving gear through the crawler track, driving the rotating nozzle to rotate, and the centrifugal force generated by the rotation can be used to spray water to a farther range, thereby increasing the spraying range, and then increasing the range of spraying dust reduction, and improving the efficiency of spraying dust reduction.
