Specific implementation mode

[0023] The present utility model will be further described below in conjunction with the accompanying drawings.

[0024] All orientations involved in this specification are based on the orientation when a multifunctional hydraulic breaker of the present utility model is working properly, without limiting its orientation during storage and transportation, only representing the relative positional relationship, not the absolute positional relationship.

[0025] Embodiment 1:

[0026] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 collectively, a multifunctional hydraulic breaker includes a breaker body 1, the top of the breaker body 1 is installed on an engineering vehicle, and a drill rod 2 is installed at its bottom. A dust cover 3 with an open bottom is installed on the breaker body 1, and the dust cover 3 covers the outside of the drill rod 2.

[0027] The dust cover 3 includes a fixing plate 30 fixed to the bottom of the breaker body 1 and a cover cylinder 31 covering the circumference of the fixing plate 30. Four mounting holes 301 are opened on the fixing plate 30, and the fixing plate 30 is fixed to the bottom of the breaker body 1 by screwing bolts into the mounting holes 301.

[0028] The cover cylinder 31 is made of an elastic material, and materials such as rubber or silicone can be used. In this embodiment, in order to improve its impact resistance and sound insulation effect, the cover cylinder 31 is provided with three layers from the inside to the outside, namely an inner rubber layer 311, a sound-absorbing cotton layer 312, and an outer rubber layer 313; the inner rubber layer 311 and the outer rubber layer 313 can improve the impact resistance and elasticity of the dust cover 3, and the sound-absorbing cotton layer 312 has a good sound insulation effect.

[0029] The cover cylinder 31 has a frustum structure, and its smallest diameter part is fixed on the fixing plate 30. With this structure, the coverage area of the cover cylinder 31 is enlarged, thereby reducing the damage caused by the flying of crushed stones to the cover cylinder 31. A plurality of annular protrusions 314 are evenly arranged in the circumferential direction of the cover cylinder 31; the annular protrusions 314 can enhance the compression capacity of the cover cylinder 31, so that when the stone is uneven, the cover cylinder 31 can still keep its bottom in contact with it, thereby avoiding dust raising or the flying out of crushed stones.

[0030] When the hydraulic breaker works, the dust cover 3 covers the outside of the drill rod 2. When the drill rod 2 collides with the stone and generates an up-and-down reciprocating vibration, the dust cover 3 will be compressed or reset along with the vibration, so as not to damage the dust cover 3.

[0031] A negative pressure port 32 is arranged in the dust cover 3, and a filter screen is arranged on the negative pressure port 32. A dust removal device 4 is connected to the negative pressure port 32. The negative pressure port 32 maintains a negative pressure state, so as to ensure that the dust is discharged from the negative pressure port 32. The negative pressure port 32 is connected to the dust removal device 4 through a dust removal pipe 321, and the dust removal device 4 treats the dust and then discharges it. The dust removal device 4 can adopt a bag dust removal device, a cyclone dust removal device, a wet dust removal device, an electrostatic dust removal device, etc., and fans are arranged on these devices, so as to ensure that the negative pressure port 32 is in a negative pressure state.

[0032] By arranging the dust cover 3, the dust cover 3 covers the outside of the drill rod 2. When the drill rod 2 works, the generated crushed stones and dust are covered by the dust cover 3, so that they will not fly out. At the same time, the dust cover 3 plays a certain role in isolating the noise generated by the collision between the drill rod 2 and the stone, thereby reducing the noise. The dust in the dust cover 3 enters the dust removal device 4 from the negative pressure port 32 for dust removal, so as to avoid part of the dust from drifting out from the bottom of the dust cover 3.

[0033] Embodiment Two:

[0034] As Figure 1 、 Figure 2 and Figure 5 collectively shown, this embodiment is improved on the basis of Embodiment One. The bag dust removal device, the cyclone dust removal device, the wet dust removal device, the electrostatic dust removal device, etc. all have relatively large volumes, so it is not convenient to install the dust removal device 4 at the construction site. Therefore, the dust removal device 4 is improved in this embodiment.

[0035] The dust removal device 4 is fixed on the breaker body 1 and includes a dust removal cylinder 41. An air inlet 401 and an air outlet 402 are arranged on the dust removal cylinder 41. The air inlet 401 is connected to the negative pressure port 32, and the air outlet 402 is connected to the external environment. A filter cylinder 42 is detachably installed between the air inlet 401 and the air outlet 402, and a fan 43 is also arranged on the air outlet 402.

[0036] Dust is driven by the fan 43 and enters the dust removal cylinder 41 from the air inlet 401. After being filtered by the filter cylinder 42, the dust falls to the bottom of the dust removal cylinder 41, while the air is discharged to the external environment from the air outlet 402 after passing through the filter cylinder 42.

[0037] To avoid interference between the intake and exhaust of the dust removal cylinder 41 and cause air flow disorder, and at the same time to achieve the cyclone separation effect, the dust removal cylinder 41 includes an inner cylinder 411 and an outer cylinder 412 that are arranged inside and outside and communicate at the bottom. The air inlet 401 is arranged on the side wall of the outer cylinder 412; the dust enters the channel between the inner cylinder 411 and the outer cylinder 412 from the air inlet 401, forming a rotating air flow. Under the action of centrifugal force, part of the dust is thrown onto the side wall of the outer cylinder 412 and thus settles, and other lighter dust enters the inner cylinder 411 from the bottom of the inner cylinder 411 along with the air flow.

[0038] An air outlet head 44 is detachably installed at the top of the inner cylinder 411, and the air outlet 402 is arranged on the air outlet head 44; the filter cylinder 42 is clamped between the air outlet head 44 and the inner cylinder 411.

[0039] A plurality of air outlets 402 are evenly arranged around the air outlet head 44, so as to achieve dispersed air outlet. A fan 43 is fixedly installed inside the air outlet head 44. The fan 43 includes a fan 431 and a motor 432. The fan 431 is rotatably installed above the filter cylinder 42, and the motor 432 is installed on the top of the air outlet head 44, and the wiring extends out of the air outlet head 44 to connect to the power supply.

[0040] The detachable installation method of the air outlet head 44 is as follows: a fixed flange is arranged on the outer cylinder 412, and an installation flange is correspondingly arranged at the bottom of the air outlet head 44. The fixed flange and the installation flange are fixedly connected by bolts, and the air outlet head 44 is fixedly installed on the top of the outer cylinder 412 through the bolts; a stepped surface 441 is arranged inside the air outlet head 44. When the air outlet head 44 is fixedly installed on the top of the outer cylinder 412, the stepped surface 441 clamps the filter cylinder 42 between the air outlet head 44 and the inner cylinder 411, and the stepped surface 441 forms a seal with the top of the filter cylinder 42.

[0041] The filter cylinder 42 includes a support plate 421 installed on the side wall of the inner cylinder 411. The support plate 421 is evenly provided with ventilation holes 422, and a net cylinder 423 extending downward is fixedly installed on each ventilation hole 422. By setting the downward-extending net cylinder 423, the area of the filter screen can be increased, thereby improving the filtration efficiency.

[0042] To facilitate pouring out the dust in the dust removal cylinder 41, a conical dust collection hopper 45 is arranged at the bottom of the dust removal cylinder 41, and a dust collection bottle 46 is screwed on the dust collection hopper 45. The dust collection hopper 45 is detachably installed at the bottom of the dust removal cylinder 41, and the installation method can adopt bolt-sealed connection, which is convenient for disassembling the dust collection hopper 45 and convenient for cleaning.

[0043] A multifunctional hydraulic breaker of the present utility model solves the technical problems in the prior art that when the hydraulic breaker is working, the flying crushed stones are likely to accidentally injure the surrounding personnel, and at the same time, the dust and noise pollute the environment, resulting in a harsh construction site environment. The present utility model is provided with a dust-proof cover outside the drill rod of the hydraulic breaker, and the dust-proof cover is connected with a dust removal device. The dust-proof cover has an isolation effect on the dust, crushed stones and noise, avoiding the flying crushed stones from accidentally injuring the surrounding personnel, and at the same time avoiding the pollution of the construction site by the dust and noise, and improving the construction environment.

[0044] Certainly, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present utility model should also belong to the protection scope of the present utility model.
