Description

Technical Field

[0001] The utility model relates to the technical field of soil excavation equipment, in particular to an automatic spraying dust reduction device. Background Art

[0002] In the existing excavation operations of excavators, dust generation is a common problem. In order to solve this problem, the current patent proposes a solution of adding a water tank and a nozzle to the excavator to reduce dust. However, this solution has some limitations. First, the spray angle of the nozzle cannot be adjusted, which may lead to uneven dust reduction effect and failure to effectively cover all dust-generating areas. Secondly, due to the lack of effective protection measures for the nozzle, it is easy to be invaded by dust during operation, resulting in nozzle clogging.

[0003] Nozzle blockage will affect the dust reduction effect, increase maintenance costs and work difficulty; clogged nozzles may need to be cleaned or replaced frequently, which will not only affect the construction progress, but also may lead to an increase in equipment failure rate.

[0004] In addition, a fixed spraying angle may not be able to adapt to different working conditions and excavation requirements; in a complex construction environment, an unadjustable spraying angle may not meet the actual dust reduction requirements.

[0005] Therefore, an improved solution is needed to solve these problems. The solution should have nozzles with adjustable spray angles to achieve more uniform and effective dust reduction. At the same time, effective nozzle protection measures should be provided to reduce the impact of dust on the nozzles and reduce the risk of nozzle clogging. Such improvements will help improve the efficiency and quality of excavator operations and reduce the impact of dust on the environment and the health of construction workers. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic spray dust suppression device, comprising a water supply mechanism and a spray mechanism arranged on an excavator, the spray mechanism comprising a C-shaped plate, a first spray plate, a second spray plate and a shielding plate, the C-shaped plate is arranged on the inner side of the forearm of the excavator close to the bucket, a sliding rod is arranged between the two ends of the C-shaped plate, the first spray plate is arranged on the C-shaped plate and is located on one side of the sliding rod, a sliding cylinder is arranged on one side of the second spray plate, the sliding cylinder is sleeved on the sliding rod and can rotate on the sliding rod, teeth are arranged on the end of the sliding cylinder, the shielding plate is arranged in the sliding grooves opened on both sides of the C-shaped plate and is located between the first spray plate and the sliding rod, and a bar tooth is arranged on one side of the shielding plate, and the bar tooth is meshed with the teeth.

[0008] Furthermore, the water supply mechanism includes a water tank and a water pump arranged in the water tank, and the water pump is connected to the first spray plate and the second spray plate through a hose, and the hose is tied to the excavator.

[0009] Furthermore, a motor is provided on one side of the C-shaped plate, and an output shaft of the motor passes through the C-shaped plate and is connected to the slide cylinder.

[0012] The utility model has the following beneficial effects:

[0013] The motor drives the slide to rotate, and then drives the second spray plate to rotate, so that the bar teeth meshing with the teeth move up, and then drives the shielding plate to move up, exposing the first spray plate located in the C-shaped plate. The angle of the second spray plate can be adjusted by the motor to adapt to different working conditions and excavation requirements; after the excavation is completed, the motor drives the second spray plate to rotate downward, and at this time, the shielding plate is synchronously driven to move downward until the shielding plate blocks the nozzle positions of the first spray plate and the second spray plate;

DETAILED DESCRIPTION

[0024] See also Figures 1 to 8 An automatic spray dust reduction device includes a water supply mechanism 2 and a spray mechanism 3 provided on an excavator 1. The water supply mechanism 2 provides water, and the spray mechanism 3 sprays the excavation position to achieve the effect of dust reduction and dust suppression. The spray mechanism 3 includes a C-shaped plate 4, a first spray plate 5, a second spray plate 6 and a shielding plate 7. The C-shaped plate 4 is provided on the inner side of the arm of the excavator 1 near the bucket. A sliding rod 8 is provided between the two ends of the C-shaped plate 4. The first spray plate 5 is provided on the C-shaped plate 4 and is located on one side of the sliding rod 8. A sliding cylinder 9 is provided on one side of the second spray plate 6. The sliding cylinder 9 is sleeved on the sliding rod 8. The first spray plate 5 and the second spray plate 6 are connected to the excavator 1 by a hose 14. The first spray plate 5 and the second spray plate 6 are connected to the excavator 1 by a hose 14.

[0025] in,

[0026] The motor 15 is specifically a stepping motor;

[0027] The first spray plate 5 and the second spray plate 6 both have multiple spray heads, which can spray multiple streams of water simultaneously;

[0028] The C-shaped plate 4 can be connected to the inner side of the forearm of the excavator 1 by welding or bolts;

[0029] The water tank 12 is specifically a high temperature resistant water tank;

[0030] The hose 14 can be tied to the excavator 1 by plastic tie bands or tie wires;

[0031] A control cabinet is provided on the excavator 1 for controlling the start and stop of the water pump 13 and the motor 15 .

[0032] The working principle of the utility model is as follows: in the initial state, the first spray plate 5 and the second spray plate 6 have nozzles respectively attached to the two sides of the shielding plate 7 for dust prevention to prevent the first spray plate 5 and the second spray plate 6 from being blocked. When the excavator 1 is digging earth, the water pump 13 and the motor 15 are started synchronously, the motor 15 drives the slide 9 to rotate, and then drives the second spray plate 6 to rotate, and during the rotation, drives the bar-shaped teeth 11 meshing with the teeth to move upward, and then drives the shielding plate 7 to move upward, exposing the first spray plate 5 located in the C-shaped plate 4, and the water pump 13 pumps the water source in the water tank 12 to the second spray plate 6 through the hose 14. The dust is sprayed from a spray plate 5 and a second spray plate 6. The angle of the second spray plate 6 can be adjusted by a motor 15 to adapt to different working conditions and excavation requirements. Since the nozzle on the first spray plate 5 is located at the bottom, the first spray plate 5 will not be blocked when the angle of the second spray plate 6 is adjusted. After the excavation is completed, the second spray plate 6 is driven to rotate downward by the motor 15, and the shielding plate 7 is driven to move downward synchronously at this time, until the shielding plate 7 blocks the nozzle position of the first spray plate 5 and the second spray plate 6. The device drives the second spray plate 6 to rotate through the motor 15 to achieve a more uniform and more effective dust reduction effect. The nozzle position of the first spray plate 5 and the second spray plate 6 is blocked by the shielding plate 7, which reduces the impact of dust on the nozzle and reduces the risk of nozzle blockage, which helps to improve the efficiency and quality of the excavator operation and reduce the impact of dust on the environment and the health of construction personnel.
