Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a dust suppression device for earth milling. Background Technology

[0002] Dust suppression devices for earth milling are used to reduce the spread of dust and particulate matter generated during civil engineering construction, particularly when using milling machines (also known as earth milling machines or road milling machines). Milling machines generate significant amounts of dust when milling, cutting, or demolishing roads, ground surfaces, or other civil structures. This dust not only pollutes the environment but also poses a threat to the health of on-site workers.

[0003] Currently, the dust suppression devices used with existing milling equipment generally suffer from simple structure and limited functionality, resulting in unsatisfactory actual dust suppression effects. In particular, the spray heads are mostly fixed installations, which cannot flexibly adjust the spray angle and direction according to the dust diffusion situation at the work site. The spray range is limited, making it difficult to effectively cover the dusty area, thus affecting the overall dust suppression efficiency.

[0004] To address the aforementioned issues, it is necessary to design a dust suppression device for earthmoving that allows for adjustment of the spray head angle. Utility Model Content

[0005] To overcome the shortcomings of most spray heads being fixed installations, which cannot flexibly adjust the spray angle and direction according to the dust diffusion conditions at the work site, this utility model provides a dust suppression device for earth milling.

[0006] The technical solution of this utility model is as follows: a dust suppression device for earth milling, including an earth milling machine, a shield, an adjustment component, an adjustment frame and a spray head. The shield is provided on the left side of the earth milling machine, the adjustment component is provided on the shield, the spray head is rotatably connected inside the shield, and the adjustment frame is connected to the spray head.

[0007] As a further preferred embodiment, the adjustment assembly includes a support frame, electric push rods, and a push plate. The support frame is connected to the upper side of the shield, and two electric push rods are mounted on the support frame. The telescopic ends of the two electric push rods pass through the shield and are connected to the push plate. The push plate is in contact with the adjustment frame for push-pull cooperation.

[0008] As a further preferred embodiment, it also includes a motor, a guide frame, a screw, a slider, a cylinder, and a push block. The milling machine is equipped with a motor and a guide frame. The left end of the motor output shaft is connected to a screw, which passes through the guide frame. A slider is slidably connected to the screw and is slidably connected to the guide frame. A cylinder is installed on the upper side of the slider, and a push block is connected to the telescopic end of the cylinder. The push block is fixedly connected to the shield.

[0009] As a further preferred option, it also includes handles; multiple handles are provided on the right side of the milling machine.

[0010] As a further preferred option, a protective shell is also included, with the milling machine equipped with a protective shell located outside the motor.

[0011] As a further preferred option, the push block adopts an inverted U-shaped design.

[0012] The beneficial effects of this utility model are as follows: By setting up two electric push rods and a push plate, the telescopic ends of the two electric push rods push the push plate to move, which in turn drives the adjustment frame to move, causing the spray head to rotate, thereby realizing flexible adjustment of the spray angle. This not only improves the automation level of the equipment, but also significantly enhances the adaptability of the spray dust suppression system, enabling it to accurately match the spray direction according to different construction environments and working conditions, thereby improving the overall dust suppression effect.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] Example: A dust suppression device for earthmoving, such as Figures 1-6As shown, the device includes a milling machine 1, handles 101, a shield 2, an adjustment assembly, an adjustment frame 6, a spray head 7, a motor 8, a protective shell 81, a guide frame 9, a screw 10, a slider 11, a cylinder 12, and a push block 13. Multiple handles 101 are located on the right side of the milling machine 1. A shield 2 is located on the left side of the milling machine 1. An adjustment assembly is installed on the shield 2, which includes a support frame 3, electric push rods 4, and a push plate 5. The support frame 3 is connected to the upper side of the shield 2, and two electric push rods 4 are mounted on the support frame 3. The telescopic ends of the two electric push rods 4 pass through the shield 2 and are connected to the push plate 5. The push plate 5 is in contact with the adjustment frame 6. A spray head 7 is rotatably connected inside the shield 2. The spray head 7 is used to atomize water and spray it out to suppress dust generated during the milling process. An adjusting frame 6 is connected, which can drive the spray head 7 to rotate with the movement of the push plate 5, so as to flexibly adjust the angle of the spray head 7 to adapt to the dust suppression needs in different directions. A motor 8 is installed on the milling machine 1. A protective shell 81 is provided on the milling machine 1. The protective shell 81 is located outside the motor 8 and protects the motor 8. A guide frame 9 is provided on the milling machine 1. A screw 10 is connected to the left end of the output shaft of the motor 8. The screw 10 passes through the guide frame 9. A slider 11 is slidably connected to the screw 10. The slider 11 is slidably connected to the guide frame 9. A cylinder 12 is installed on the upper side of the slider 11. A push block 13 is connected to the telescopic end of the cylinder 12. The push block 13 is fixedly connected to the shield 2. The push block 13 adopts an inverted U-shaped design. The push block 13 can transmit the thrust of the cylinder 12 to the shield 2.

[0022] When this device is needed, the operator first starts the motor 8. The output shaft of the motor 8 drives the screw 10 to rotate. The screw 10 drives the slider 11, cylinder 12, push block 13, and shield 2 to move to the left along the guide frame 9. The movement of the shield 2 causes all its components to move to the left until the shield 2 moves to the appropriate position. Then, the motor 8 is turned off. Next, the cylinder 12 is started. The extension end of the cylinder 12 drives the push block 13 and shield 2 to move upward. The shield 2 causes all its components to move upward until the shield 2 moves to the appropriate height. Then, the cylinder 12 is turned off, completing the initial position adjustment of the equipment. Next, the milling machine 1 is placed on the ground to be worked on, and the external water pipe is connected to the interfaces on both sides of the spray head 7. After confirming that the connection is correct, start the milling machine 1. The milling machine 1 will begin to perform milling operations. During the operation, the workers can push the milling machine 1 to move flexibly to complete the construction tasks in different areas. In order to achieve efficient dust suppression, water enters the interior of the spray head 7 through the external pipe while the milling operation is underway. The spray head 7 will then spray water mist evenly to suppress dust. If it is necessary to adjust the spray angle of the spray head 7, the two electric push rods 4 can be activated. The telescopic ends of the two electric push rods 4 will push the push plate 5 and the adjustment frame 6 downward, thereby causing the spray head 7 to rotate. When the spray head 7 is adjusted to the required angle, the two electric push rods 4 can be turned off to complete the angle adjustment of the spray head 7 and ensure that the spraying effect meets the needs of the current working environment.
