Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction devices, in particular to a dust reduction device for civil engineering. Background Technique

[0002] During the construction process of civil engineering, a large amount of dust will be generated. The dust floating in the air poses a threat to the health of construction workers and also affects the construction progress. Spraying dust reduction devices are often used at construction sites to spray water into the air to achieve the purpose of dust reduction.

[0003] At present, the existing dust reduction devices for civil engineering use the method of spraying water mist to reduce dust. After the dust is attached to the water droplets, it falls to the ground, thus completing the dust reduction operation. However, this dust reduction method cannot clean the dust in time. As time goes by, more and more dust accumulates, thus reducing the subsequent dust reduction efficiency. In addition, when cleaning the dust, the dust suction range is limited, and the dust on both sides of the bottom of the device cannot be cleaned, resulting in a low dust suction efficiency.

[0004] Therefore, aiming at the above-mentioned existing dust reduction devices for civil engineering, which can only spray water mist to reduce dust, cannot clean the dust on the ground in time, and the dust on both sides of the bottom of the device cannot be cleaned during the cleaning process, resulting in a low dust suction efficiency, a dust reduction device for civil engineering can be designed. By setting a dust suction component, when a person pushes the dust reduction device to move, the fan can suck the dust at the bottom of the bottom plate into the dust collection box through the dust suction cover, dust suction pipe and dust discharge pipe, so as to clean the dust in time and improve the subsequent dust reduction efficiency. By setting a cleaning component, the dust on both sides of the bottom of the device can be swept towards the middle, and in cooperation with the dust suction component, the dust suction efficiency is improved. Content of the Utility Model

[0005] In order to overcome the problem that the existing dust reduction devices for civil engineering can only spray water mist to reduce dust and cannot clean the dust on the ground in time, thus reducing the subsequent dust reduction efficiency.

[0006] The technical solution of the utility model is as follows: A dust reduction device for civil engineering, including a bottom plate; further including a dust suction component. On the left side of the top of the bottom plate, there is a fixed installation shell. Inside the installation shell, there is a fixed partition plate. On the top of the partition plate, there is a dust suction component. The dust suction component includes a fan, a dust suction pipe, a dust suction hood, a dust discharge pipe, a dust collection box, and a filter screen; on the top of the partition plate, there is a fixed fan. The suction end of the fan is fixedly provided with a dust suction pipe. On the bottom of the bottom plate, there is a fixed dust suction hood. The other end of the dust suction pipe penetrates through the bottom plate and is opened on the top of the dust suction hood. The air outlet end of the fan is fixedly provided with a dust discharge pipe. The other end of the dust discharge pipe is opened on the top of the partition plate. At the bottom inside the installation shell, there is a dust collection box. The dust collection box is slidably connected to the installation shell. On the back of the installation shell, there is a filter screen. The filter screen is located between the partition plate and the dust collection box.

When the operator screws the installation screw on the brush into the installation hole on the installation box, the installation of the brush can be completed. The rotation direction of the installation screw during installation is opposite to the rotation direction of the output shaft of the motor, thus avoiding loosening during the cleaning of the brush.

[0010] As a preference, the spraying component includes an installation seat 1 and a spraying machine; on the rightmost side of the top of the bottom plate, there is a fixed water tank. On the left side of the top of the water tank, there is a fixed installation seat 1. Inside the installation seat 1, there is a hinged spraying machine. The setting of the installation seat 1 facilitates the installation of the spraying machine, enabling the spraying machine to rotate on the installation seat 1, and thus facilitating the adjustment of its angle.

[0012] Preferably, an observation window is provided on the right side of the front of the water tank, and the opening of the observation window facilitates the operator to observe the remaining water volume inside the water tank.

[0013] Preferably, universal wheels are fixedly arranged at the four corners of the bottom of the bottom plate, and a push-pull rod is fixedly arranged at the leftmost side of the top of the bottom plate. When the operator pushes the push-pull rod, the dust suppression device can be driven to move in cooperation with the universal wheels.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By setting the dust suction assembly, when the operator activates the fan, the fan can suck the dust at the bottom of the bottom plate into the lower end of the partition through the dust suction cover, the dust suction pipe, and the dust discharge pipe. At this time, the filter screen can intercept the dust, and the dust can thus enter the inside of the dust collection box, so as to clean the dust on the ground in time and improve the subsequent dust suppression efficiency;

[0016] 2. By setting the cleaning assembly, when the operator activates the motor, the output shaft of the motor can drive the installation box to rotate, and then drive the brush to rotate. The brush can thus sweep the dust at the bottom of the bottom plate towards the middle, which is convenient for the dust suction of the dust suction cover. The two cooperate with each other to improve the dust suction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
