Description

TECHNICAL FIELD

[0001] The utility model relates to hydraulic breaking hammer technical field, concretely is a kind of for the water spray plate of hydraulic breaking hammer. BACKGROUND

[0002] In actual work, the piston of hydraulic breaking hammer accelerates to strike drill rod, and the drill rod collides with target object to achieve the breaking effect on target object. When hydraulic breaking hammer is applied in demolition and tunnel work, it will be struck for a long time with the drill rod upward, i.e. the working condition with the drill rod upward. In the process of the drill rod colliding with the target object, a large amount of fine dust will be generated at the tip of the drill rod due to the collision between the drill rod and the target object. The dust will accumulate on the lower end surface of the front cylinder body under the impact of the airflow generated by the collision and the action of gravity. At this time, part of the dust will pass through the outer sleeve and the inner sleeve of the front cylinder body, the dustproof seal of the middle cylinder body, the two main oil seals and the buffer oil seal to finally enter the hydraulic oil.

[0003] In addition, when the piston rises rapidly, negative pressure will be formed inside the striking cavity, and part of the butter and dust in the inner sleeve will be sucked into the striking cavity. When the dust in the hydraulic oil accumulates to a certain amount, the hydraulic oil will become black, which will affect the normal performance of the hydraulic oil. The phenomenon that the dust pollutes the hydraulic oil to cause the color change of the hydraulic oil is called "black oil" phenomenon. When the black oil phenomenon occurs, the hydraulic oil needs to be replaced in time.

For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0030] Embodiment 1

[0031] In order to solve the above problems, the utility model provides a technical scheme: as Figures 1-4 As shown in a kind of water spray plate for hydraulic breaking hammer, including water spray plate body 1, multiple staggered intercommunication water channels, multiple plugs, multiple water spray adapters, water inlet hole, multiple connecting holes 601 are equipped on water spray plate body 1, water spray plate body 1 is fixed in the uppermost surface of the shell of hydraulic breaking hammer 7 by multiple connecting holes 601, multiple staggered intercommunication water channels are equipped in water spray plate body 1, one end of multiple water channels is blocked by plug, and plug is installed in the side of water spray plate body 1, more conducive to observing and finding plug damage, convenient to install and disassemble, the other end of at least one water channel is connected with water inlet hole, the other end of remaining water channel is blocked by plug, multiple water spray adapters are equipped above water spray plate body 1, water spray adapter is vertically communicated with water channel, water spray adapter is connected with water spray head, water inlet hole is connected with certain pressure liquid, certain pressure liquid is provided by additional water pump on excavator, and water pump is installed in water tank on excavator.

[0032] This invention designs a water spray plate for a hydraulic breaker. In use, the water spray plate is fixed to the top of the hydraulic breaker's housing via connecting holes 601. During normal operation, liquid at a certain pressure enters through the inlet hole, passes through multiple interconnected water channels, and exits from spray heads connected to multiple spray adapters. Different spray heads have different effects; the most widely used adapter is the atomizing adapter, which atomizes the liquid and sprays it evenly around the housing, reducing dust around the hydraulic breaker, optimizing the working environment, and preventing dust contamination of the hydraulic oil, thus avoiding discoloration.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 is that:

[0035] like Figures 1-4 As shown, there are four water channels: the first water channel 401, the second water channel 402, the third water channel 403, and the fourth water channel 404. The first water channel 401 and the second water channel 402 are located on the left and right sides of the water spray plate body 1, and the third water channel 403 and the fourth water channel 404 are located on the front and rear sides of the water spray plate body 1, and they are all perpendicularly connected to the first water channel 401 and the second water channel 402.

[0036] The system employs four vertically interconnected water channels, which can effectively and evenly inject the liquid from the inlet holes into each spray head.

[0037] There are 6 plugs, namely the first plug 201, the second plug 202, the third plug 203, the fourth plug 204, the fifth plug 205, and the sixth plug 206. The first plug 201 and the fourth plug 204 are installed at both ends of the third waterway 403, the fifth plug 205 and the sixth plug 206 are installed at both ends of the fourth waterway 404, the second plug 202 is installed at one end of the first waterway 401, and the fourth plug 204 is installed at one end of the second waterway 402.

[0038] There are two water inlets, namely the first water inlet 501 and the second water inlet 502. The first water inlet 501 is installed at the other end of the first water passage 401, and the second water inlet 502 is installed at the other end of the second water passage 402.

[0039] Since the water pressure is relatively low when using only one water inlet, this invention prioritizes two water inlets. This design facilitates the application of optimal water pressure to the four vertically interconnected water channels.

[0040] The number of the water spraying adapters is six, which are the first water spraying adapter 301, the second water spraying adapter 302, the third water spraying adapter 303, the fourth water spraying adapter 304, the fifth water spraying adapter 305 and the sixth water spraying adapter 306.

[0041] The water spraying adapter is arranged on the outer periphery of the water spraying plate body 1, which is more conducive to uniformly spraying around the shell body and can reduce the dust around the hydraulic breaking hammer.

[0042] It should be noted that the number and position of the water path, plug, water inlet hole and water spraying adapter can be adjusted as needed, and the above examples are not intended to limit the scope of the utility model, but only to better explain the working principle of the utility model.

[0043] In the description of the utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0044] In the description of the utility model, the description of the reference terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In the description of the utility model, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0045] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
