[0002] Construction projects refer to all kinds of buildings and engineering facilities that provide the material and technical foundation for human life and production. In fact, before the entire construction process, it is often necessary to use engineering quality testing excavators to break ground and test the foundation, building materials, construction technology, and building structure related to the building.

[0003] When the soil breaker is working, the soil-breaking roller installed on the device rotates to enter the soil to break it up. During the soil breaking process, a lot of dust is generated and flies around the soil breaker. The dust will greatly reduce the visibility at the soil breaking operation site, making it difficult for the operator to accurately judge the soil breaking situation and surrounding obstacles, thus affecting the normal use of the soil breaker. Utility Model Content

[0022] Example 1, as Figure 1-3 As shown, a construction engineering excavator includes a frame 1. An auxiliary rod 4 is fixedly connected to one side of the frame 1. Two rotating shafts 8 are rotatably connected to the bottom of the frame 1, and two movable wheels 9 are fixedly connected to their ends. A hydraulic rod 5 is installed at the top of the frame 1, with its output rod located below the top of the frame 1. A mechanical rod 6 is slidably mounted on the outer surface of the frame 1, with its output rod connected to the top of the mechanical rod 6. A breaking roller 7 is rotatably mounted at the bottom of the mechanical rod 6. A drive motor (not shown) for driving the breaking roller 7 is installed on one side of the mechanical rod 6. A dust suppression device 2 is installed on one side of the frame 1 to suppress the dust generated during the soil breaking process. When using the soil breaking device, the auxiliary rod 4 on the top side of the frame 1 is connected to the hook of the traction device. Then, the drive motor on the side of the rod 6 is controlled by the control panel on the side of the frame 1 to drive the soil breaking roller 7 to rotate. The hydraulic rod 5 is operated to extend and control the rod 6 to slide downward on the outer surface of the frame 1 to adjust the height of the soil breaking roller 7. Then, the frame 1 is pulled by the traction device to rotate and move its position through the rotating shaft 8 and the moving wheel 9. The rotating soil breaking roller 7 is inserted into the ground to break the soil.

[0023] Reference Figure 1-5As shown in this embodiment: the dust suppression device 2 includes a water tank 21 and a support rod 23. The water tank 21 is fixed to the top of the frame 1, and a water injection pipe is provided at the top of the water tank 21. The support rod 23 is fixed to one side of the outer surface of the frame 1. Several short pipes 24 are provided at the bottom of the support rod 23. The end of the short pipe 24 away from the support rod 23 is connected to a nozzle 25 through a flexible hose. Two springs 27 are provided at the bottom of the support rod 23. A rectangular rod 26 is provided at the bottom of the springs 27. The upper and lower ends of the springs 27 are fixedly connected to the outer surface of the support rod 23 and the top of the rectangular rod 26, respectively. The bottom of the rectangular rod 26 is connected to each nozzle. The top of the frame 1 is fixedly connected to the water tank 21. A pump 22 is installed on the top of the frame 1 near the water tank 21. The two ends of the pump 22 are connected to the top of the water tank 21 and the top of the frame 23 respectively through pipes. Sliding rods 28 are slidably connected to both sides of the frame 1. Push rods 29 are fixedly connected to both ends of a rotating shaft 8. By setting the nozzle 25, water can be added to the water tank 21 through the water injection pipe at the top of the water tank 21 when the excavator is used. When the excavator is operating, the pump 22 at the top of the frame 1 is controlled to operate, and the pump 22 draws water from the water tank 21 and transmits it through the pipe to the short end at the bottom of the frame 23. At pipe 24, the water then enters the nozzle 25 and sprays out. Simultaneously, as the soil breaker moves, the rotating shaft 8 rotates. When the push rod 29 on the outer surface of the rotating shaft 8 enters one side of the sliding rod 28, it contacts the outer surface of the sliding rod 28, pushing the sliding rod 28 upwards. This causes the top of the sliding rod 28 to push the rectangular rod 26, which in turn moves the nozzle 25 upwards a certain distance and compresses the spring 27. When the push rod 29 moves away from the outer surface of the sliding rod 28, the spring 27 returns to its original state, pushing the rectangular rod 26 downwards back to its original position. This allows the water sprayed from the nozzle 25 to oscillate up and down within a certain range. Above the breaking roller 7, water mist sprayed from the nozzle 25 is used to suppress dust generated during the breaking process. By setting up the dust suppression device 2, when the breaking machine is used, water is added to the water tank 21. When the breaking machine is working, the pump 22 is operated to pump the water from the water tank 21 to the nozzle 25. With the help of the rotation of the rotating shaft 8, the rectangular rod 26 drives the nozzle 25 to swing up and down, so that the nozzle 25 swings and sprays mist water to suppress the dust generated during the breaking process. This avoids a large amount of dust reducing the visibility at the breaking machine and affecting the operator's observation and judgment.

[0024] Reference Figure 2-5As shown in this embodiment: two round rods 210 are fixedly connected to the top of the rectangular rod 26. The top of the round rods 210 slides on the inner wall of the frame rod 23. When the rectangular rod 26 moves up and down, the round rods 210 will slide on the inner wall of the frame rod 23. By setting the round rods 210, the angle between the rectangular rod 26 and the frame rod 23 can be limited, avoiding the angle of the left and right ends of the rectangular rod 26 from deflecting. A transparent plate 211 is fixedly connected to one side of the water tank 21. The transparent plate 211 is made of PC material. By setting the transparent plate 211 made of PC material, the operator can easily observe the water level inside the water tank 21 and add water in time. A pad 212 is fixedly connected to the bottom of the slide rod 28. The pad 212 is made of rubber material. After the slide rod 28 is pushed upward by the push rod 29, the pad 212 at the bottom can buffer the contact between the slide rod 28 and the frame 1 when the slide rod 28 descends, so that the slide rod 28 will not bounce up again due to the impact with the frame 1 after descending.

[0025] Reference Figure 1 , Figure 2 and Figure 3 and Figure 4 as well as Figure 6 As shown in this embodiment: a protective device 3 is provided on the outer surface of the nozzle 25. The protective device 3 includes a round cover 32. A protruding strip 33 is fixedly connected to one end of the inner wall of the round cover 32. A protruding ring 31 is fixedly connected to the outer surface of the nozzle 25. The protruding strip 33 is made of rubber. When the dust suppression device 2 or the soil breaker is not used, a round cover 32 can be placed on one side of the nozzle 25. When the protruding strip 33 on the inner wall of the round cover 32 comes into contact with the protruding ring 31 on the outer surface of the nozzle 25, it will be squeezed. After the protruding strip 33 enters the other side of the protruding ring 31, it will lock the round cover 32 on the outside of the nozzle 25. The round cover 32 seals the nozzle 25, so as to avoid dust and other environmental particles from entering the nozzle 25 and causing the nozzle 25 to become blocked.

[0026] Reference Figure 2 and Figure 3 and Figure 4 as well as Figure 6 As shown in this embodiment: a magnetic block 34 is fixedly connected to one side of the round cover 32, and the rectangular rod 26 is made of metal iron. When using the dust suppression device 2, after removing the round cover 32, the magnetic block 34 on one side of the round cover 32 can be attached to the outer surface of the rectangular rod 26 and magnetically attracted to the rectangular rod 26, which facilitates the temporary storage and fixation of the round cover 32. An elastic rope 35 is fixedly connected to one side of the round cover 32. The end of the elastic rope 35 away from the round cover 32 is fixedly connected to the bottom side of the support rod 23. By setting the elastic rope 35, the round cover 32 can always be fixed to the outside of the support rod 23, preventing the round cover 32 from falling off the outer surface of the rectangular rod 26 and being lost.

[0027] Working principle: When using the soil breaker, water is added to the water tank 21 through the water injection pipe at the top of the water tank 21. When the soil breaker is in operation, the auxiliary rod 4 on one side of the top of the frame 1 is connected to the hook of the traction device. Then, the drive motor on one side of the rod 6 is controlled by the control panel on one side of the frame 1 to drive the soil breaking roller 7 to rotate. The hydraulic rod 5 is operated to extend and control the rod 6 to slide downward on the outer surface of the frame 1 to adjust the height of the soil breaking roller 7. Then, the traction device pulls the frame 1 to rotate and move its position through the rotating shaft 8 and the moving wheel 9. The rotating soil breaking roller 7 inserts into the ground to break the soil. At the same time, the pump 22 at the top of the frame 1 is controlled to operate. The pump 22 pumps water from the water tank 21 and transmits it through the pipeline to the bottom of the rod 23. At the short pipe 24, the water enters the nozzle 25 and sprays out. At the same time, as the soil breaker moves, the rotating shaft 8 rotates. When the push rod 29 on the outer surface of the rotating shaft 8 enters one side of the slide rod 28, it contacts the outer surface of the slide rod 28 and pushes the slide rod 28. This controls the slide rod 28 to move upward, causing the top of the slide rod 28 to push the rectangular rod 26. The rectangular rod 26 then drives the nozzle 25 to move upward a certain distance and compresses the spring 27. When the push rod 29 moves away from the outer surface of the slide rod 28, the spring 27 returns to its original state and pushes the rectangular rod 26 downward back to its original position. This allows the water sprayed from the nozzle 25 to swing up and down within a certain range and spray above the soil-breaking roller 7. The water mist sprayed from the nozzle 25 is used to suppress the dust generated during the soil breaking process.
