Description

Technical Field

[0001] This utility model relates to the field of hydraulic breaker technology, specifically to a detachable dust removal and noise reduction device for hydraulic breakers. Background Technology

[0002] Hydraulic breakers are typically mounted on excavators and are mainly used for breaking up surfaces in building and road construction. During operation, they generate a large amount of dust, and the breaking process can cause stones to fly, posing a danger to pedestrians and vehicles. Currently, construction sites typically use a mist cannon to suppress the dust generated by hydraulic breakers. However, this mist cannon needs to continuously spray water mist even when the breaker is not breaking surfaces, and it lacks precise dust collection, consumes a lot of water, and wastes energy. To address this problem, a new technology has been invented... The dust hood installed around the breaker hammer contains a water outlet pipe. When the breaker hammer is working, the dust hood shields the perimeter of the work area, effectively preventing dust and particulate matter from splashing. The nozzles of the water outlet pipe spray dust-suppressing water into the dust hood, causing the dust to settle quickly. However, after prolonged operation, due to the large amount of fine particles mixed in with the dust, these impurities can easily clog the nozzles of the water outlet pipe. The spray water used for operation can also easily cause scale to form inside the nozzles. All of these situations can lead to limited water output and affect normal dust suppression operations. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-3 As shown, this utility model embodiment provides a detachable dust removal and noise reduction device for a hydraulic breaker, including a mounting frame 1 installed on the excavator's robotic arm. A hydraulic breaker 2 is installed inside the mounting frame 1. A dust cover 3 is installed around the hammer head of the hydraulic breaker 2. A water distribution pipe 4 is arranged around the hydraulic breaker inside the dust cover 3. A water supply pipe 5 is installed on the water distribution pipe 4 and extends outward from the dust cover 3. The water supply pipe 5 is connected to a water tank on the excavator frame through a water pipe. Water outlet pipes 6 are evenly distributed at the lower end of the water distribution pipe 4 and extend downward. A water outlet nozzle 7 is installed at the lower end of the water outlet pipe 6. A splash baffle 8 is installed directly below the water outlet nozzle 7. A blockage removal component is installed at the lower end of the splash baffle 8.

[0020] The bottom of the water nozzle 7 is provided with several water outlets 7a, which are arranged facing the splash baffle 8. The lower end of the splash baffle 8 is provided with a retractable movable plate 9. The upper end of the movable plate 9 is provided with a cleaning needle 10 at the position corresponding to each water outlet 7a. The splash baffle 8 is provided with a clearance hole 8a at the position corresponding to each cleaning needle 10. The upper end of the cleaning needle 10 passes through the clearance hole 8a and extends to the upper end of the splash baffle 8. The diameter of the cleaning needle 10 is not greater than the diameter of the water outlet 7a.

[0021] The splash baffle 8 has vertical sliding rods 11 on both sides at its lower end. The two ends of the movable plate 9 are slidably sleeved on the sliding rods 11. The bottom of the sliding rods 11 is provided with a limiting block 12 to prevent the movable plate 9 from falling. The sliding rods 11 are also provided with a telescopic spring 13. The upper end of the telescopic spring 13 abuts against the bottom of the splash baffle 8, and the lower end of the telescopic spring 13 abuts against the upper end of the movable plate 9.

[0022] The splash baffle 8 has a conical structure, with the protruding tip of the splash baffle 8 facing the side of the water outlet nozzle 7.

[0023] The splash baffle 8 has mounting rods 14 on both sides of its upper end, and the mounting rods 14 are fixedly connected to the side wall of the water outlet pipe 6.

[0024] Mounting bracket 1 has a buffer seat on its outer side, and dust cover 3 is installed with the buffer seat.

[0025] The buffer seat includes a cylindrical seat 15 fixed to the side wall of the mounting frame 1. A mounting arm 16 is provided inside the cylindrical seat 15. The two ends of the mounting arm 16 extend through the upper and lower ends of the cylindrical seat 15 and outward from the cylindrical seat 15. A retaining edge 17 is provided in the middle of the part of the mounting arm 16 located in the cylindrical seat 15. Shock-absorbing springs 18 are sleeved at the upper and lower ends of the retaining edge of the mounting arm 16. The two shock-absorbing springs 18 are located inside the cylindrical seat 15. The two ends of the shock-absorbing springs 18 abut against the retaining edge 17 and the inner wall of the cylindrical seat 15, respectively. The lower end of the mounting arm 16 is fixedly connected to the top of the dust cover 3.

[0026] The dust cover 3 has a mounting post 19 on its top, and the lower end of the mounting arm 16 is fixedly connected to the top of the mounting post 19.

[0027] Since the breaker will vibrate during operation, the dust cover 3 and the mounting bracket 1 are connected in a movable manner. Two damping springs 18 restrict the dust cover 3 to one position. When the breaker is working, it mainly vibrates in the up and down direction. As a result, the dust cover 3 drives the mounting arm 16 to swing slightly up and down in the cylinder seat 15 with the vibration of the breaker, thus playing a buffering role. The two damping springs 18 work together to make the dust cover 3 swing up and down within a range, reducing the impact of vibration on the dust cover 3.

[0028] The working principle of this utility model is as follows: A water pump is installed in the water tank of the excavator frame. The water pump is connected to the water supply pipe 5 through a water pipe. The breaker hammer 2 contacts the ground and performs breaker operation. While the breaker hammer is working, the water pump sends water from the water tank to the water distribution pipe 4. Then, through the diversion of each water outlet pipe 6, it is sprayed out at each water outlet nozzle 7. The sprayed water will hit the splash baffle 8. At this time, the sprayed water is splashed up, thus forming a barrier of water mist and water droplets on the dust cover 3, which prevents the dust generated during operation from being mixed with the water spray. Water droplets come into contact with and are captured, effectively preventing dust generation. Small stones that splash up can also be blocked by the dust cover 3, preventing them from splashing outwards. As working time increases, the water outlet 7a may become clogged. At this time, press the bottom of the movable plate 9 upwards, causing the movable plate 9 to move upwards. The upward movement of the movable plate 9 will drive the cleaning needle 10 to extend into the interior of each water outlet 7a, thereby clearing away the clogged impurities and ensuring that the water nozzle 7 can spray normally.

[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
