Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery, and in particular to a breaker with an autonomous dust suppression function. Background Art

[0002] Hydraulic breaker is usually installed on excavators or loaders, and is mainly used for crushing, demolition, excavation of hard layers, mining and other work in construction. It is widely used because of its advantages such as strong impact force, easy use, good mobility and high efficiency. When the hydraulic breaker is working, the piston hits the drill rod at high speed. When the drill rod contacts the object to be broken, a shock wave is generated and the impact energy is transferred to the surface of the object, causing the object to break, which may generate a lot of dust. At present, a fog cannon truck is usually specially arranged on the construction site for dust reduction.

[0003] Since dust removal by mist cannon trucks requires separate equipment and personnel, the cost of use is high. In addition, the working range of the breaker is large during operation. In order to achieve the ideal dust removal effect, the mist cannon truck often needs to be moved with the machine, which has the disadvantages of inflexible operation and untimely dust removal. In addition, there are great safety hazards in transferring the mist cannon truck back and forth at the construction site.

[0004] When the mist cannon truck is performing dust removal operations, it needs to keep spraying water mist even in the gaps when the breaker hammer is not breaking. In addition, the mist cannon truck cannot capture dust accurately, consumes a lot of water, and causes energy waste. Summary of the invention

[0005] The purpose of the present invention is to provide a breaker with an intelligent dust suppression system to solve the problems of high dust suppression cost, inflexible operation, great safety hazards, unsatisfactory dust suppression effect and serious waste of resources when the current breaker is working.

[0007] The top dust removal device includes a mounting plate, at least one first nozzle is installed on the bottom surface of the mounting plate, a plurality of channels for conveying water are opened inside the mounting plate, and the channels are interconnected. A valve connected to an external water pipe is installed at the front section of one of the channels for controlling the switch of the water channel, and plugs are installed at the openings of the other water channels for sealing.

[0008] The first nozzle is an atomizing nozzle, and the first nozzle is connected to the mounting plate through threads.

[0009] A nozzle protection plate is provided on the mounting plate at each first nozzle, and the bottom plane of the nozzle is lower than the bottom plane of the protection plate, so that the first nozzle is embedded in the hole of the protection plate.

[0025] The present invention will be further explained below in conjunction with the accompanying drawings.

[0026] like Figure 1As shown, a breaker hammer with an intelligent dust suppression system of the present invention includes a breaker hammer body 1, and the breaker hammer body 1 is installed on a connection system 2 of an excavator or a loader. The excavator or the loader also includes at least: a driving system 3 for walking, a frame 4, a water supply system 5 and a driving system 6 for operating and controlling the machine.

[0027] like Figure 2 As shown, the breaker body 1 includes a shell 13, a top plate 19 is arranged on the top of the shell 13, a top dust removal device 12 is arranged on the top of the top plate 19, a connecting bracket 11 is arranged on the top of the top dust removal device 12, the connecting bracket 11 is connected to the top plate 19 by a connecting bolt 16, and the connecting bracket 11 is used to connect with the connecting system 2 of the excavator or loader; a bottom dust removal device 18 is arranged at the bottom of the shell 13, a core body 14 is arranged in the shell 13, a drill rod 15 is connected to the lower end of the core body 14, and the drill rod 15 passes through the bottom dust removal device 18; the top dust removal device 12 is connected to an external water pipe 30, the external water pipe 30 is connected to the water supply system 5 of the excavator or loader, and a conveying water pipe 17 is connected between the top dust removal device 12 and the bottom dust removal device 18.

[0028] The connecting bracket 11 is connected to the top plate 19 by connecting bolts 16. The top dust removal device is configured as a detachable module, which can be selectively installed according to requirements, and the device can be installed on other breaking hammers, which is economical and practical.

[0029] like Figures 3 to 5 As shown, the top dust removal device 12 includes a mounting plate 20, at least four first nozzles 21 are installed on the bottom surface of the mounting plate 20, and four channels for conveying water are opened inside the mounting plate 20, namely the first channel 121, the second channel 122, the third channel 123, and the fourth channel 124. The channels are interconnected, and a valve 22 connected to an external water pipe 30 is installed at the front section of the first channel 121 for controlling the switch of the water channel, and plugs 23 are installed at the openings of the other water channels for sealing.

[0030] The first nozzle 21 is an atomizing nozzle, which has the advantages of good spraying effect, long range, and large coverage area. When working, it can produce a large number of fine atomized water droplets 212 to capture dust 31 generated by crushing. The first nozzle 21 is connected to the mounting plate 20 by threads, which is convenient for installation and replacement.

[0031] A nozzle protection plate 24 is provided on the mounting plate 20 at each first nozzle 21, which can be connected together by welding or other methods. The plane of the nozzle bottom 211 is lower than the plane 242 of the bottom of the protection plate, so that the first nozzle is embedded in the hole of the protection plate, which plays a role in protecting the first nozzle. The mounting plate 20 is cylindrical, and its inner wall is a conical surface 241 that is narrow at the top and wide at the bottom, so as to prevent interference with the water mist sprayed by the first nozzle 21 and affect the dust suppression effect.

[0032] like Figures 6 to 7 As shown, the bottom dust removal device 18 includes a mounting base plate 25, on which four second nozzles 26 are mounted, namely, a second nozzle I 261, a second nozzle II 262, a second nozzle III 263, a second nozzle IV 264, The second nozzle 26 is a fan-shaped nozzle, which has the advantages of a large and smooth spray channel and is not easily blocked. When working, it can generate spray particles 261 that directly act on the surface of the crushed object 31.

[0033] The second nozzle 26 is installed in the second nozzle installation hole 251 opened in the installation base plate 25. The inner wall of the second nozzle installation hole 251 is a conical surface, and the second nozzle 26 is completely embedded in the installation base plate 25. This protects the second nozzle from being hit by fragments generated by the breaker object 31 or blocked by dust from 311, and does not affect the dust suppression effect of the spray.

[0034] The upper end of the second nozzle 26 is connected to a three-way joint 271 or a right-angle elbow 272 through a thread, and a bottom plate groove 252 is opened on the upper surface of the mounting bottom plate 25. A connecting pipe 28 is arranged in the bottom plate groove 252. Multiple three-way joints 271 and right-angle elbows 272 are connected by the connecting pipe 28 to form a water path, and the lower end of the water delivery pipe 17 is connected to one of the three-way joints 271.

[0035] The water delivery pipe 17 is located in the housing 13 , and the upper end of the water delivery pipe 17 is connected to the top dust removal device 12 , and a bottom dust removal device valve 29 is provided at the connection.

[0036] The top dust removal device and the bottom dust removal device of the intelligent automatic dust removal breaker of the present invention are two independent dust suppression systems. The dust suppression device can be selected to be turned on according to the size of the dust generated by the crushing object, or both can be turned on at the same time. This function saves energy while achieving the dust suppression function. The top dust suppression device can capture a wide range of dust, mainly through the collision and condensation of atomized water droplets with dust particles. As the scale and mass continue to increase, they condense into larger and heavier powders and fall. The bottom dust removal device can spray water directly onto the head of the drill rod and the object being crushed by the hammer to suppress the generation of dust, and achieve the dust removal effect efficiently.

[0037] The working process of the present invention is: like Figure 8As shown, before the crushing operation begins, the top dust removal device valve 22 and the bottom dust removal device valve 29 connected to the external water pipe 30 are opened. Its working principle: when the operator steps on the foot valve 36 in the control driving system 6, the pilot oil pressure is output at this time, and the pilot output signal is connected to the solenoid valve 35, which is a two-position three-way structure. One end of the inlet of the solenoid valve 35 is connected to the water pump 33 in the working system 5, and the water pump 33 is connected to the power supply 32 and powered by the power supply 32. In order to avoid the delay of the nozzle spraying water, the water pump 33 is set to be always open; the first outlet of the solenoid valve 35 is connected to the water tank 34, and the second outlet of the solenoid valve 35 is connected to the external water pipe 30 of the crushing hammer dust removal device. Before the machine is normally started, the first outlet of the solenoid valve 35 is normally open and normally connected to the water tank 34. When the foot valve 36 that makes the crushing hammer work is stepped on, the crushing hammer performs normal crushing operation at this time. When the crushing hammer drill rod contacts the crushed object, a shock wave will be generated, and the impact energy will be transmitted to the surface of the crushed hammer object, so that the object is crushed, and a large amount of undesirable dust will be generated when the object is crushed. At this time, the solenoid valve 35 receives the pilot signal, and the solenoid valve 35 works to close the first outlet waterway connected to the water tank 34, and open the second outlet of the waterway 30 connected to the top dust removal device 12 and the bottom dust removal device 18, so that the crushing hammer dust suppression device works. When the foot valve 36 is stopped, the breaker 1 stops the crushing work, and no dust will be generated at this time. After receiving the pressure signal, the solenoid valve 35 switches the water path again: the solenoid valve 35 closes the second outlet water path of the top dust removal device 12 and the bottom dust removal device 18, and opens the first outlet water path of the return water tank 34. At the same time, the top dust removal device valve 22 and the bottom dust removal device valve 29 can be opened or closed according to the requirements of the working environment and the amount of dust. This intelligent dust suppression system can timely, effectively and accurately prevent construction dust, improve the working environment, and prevent air pollution; it can also minimize the use of water, save energy and reduce emissions, and has low maintenance costs, which is economical and practical.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
