[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0034] Please refer to Figure 1 and Figure 2 The water delivery structure 100 for a high-frequency breaker, the high-frequency breaker and the excavation equipment provided in the embodiments of the utility model can solve the above-mentioned problems, which will be described in detail below.

[0035] The water supply structure 100 for the high-frequency breaker includes an external water channel 110 for supplying water to a first nozzle 130 and an internal water channel 120 for supplying water to a second nozzle 140; wherein the external water channel 110 is located in an external water pipe 180 outside a vibration output part 190 of the high-frequency breaker, and the internal water channel 120 is opened in the vibration output part 190.

[0036] The water supply structure 100 for the high-frequency breaker can realize external water spraying through the external water channel 110 and internal water spraying through the internal water channel 120. On the one hand, it can realize large-scale spraying, and on the other hand, it can accurately spray the source of dust at the moment of dust generation, thereby slowing down the dispersion of dust.

[0037] Specifically, the vibration output part 190 includes a connected drill rod 191 and a bucket tooth seat 192 , and the internal water channel 120 includes a front water channel 121 and a rear water channel 122 that are connected. The front water channel 121 is opened in the drill rod 191 , and the rear water channel 122 is opened in the bucket tooth seat 192 .

[0038] refer to Figure 1 and Figure 2In order to reduce the processing difficulty and reduce the negative impact on the strength of the drill rod 191, a first groove 193 may be provided on the top surface of the drill rod 191. The first groove 193 is used to enclose the outer water pipe 180 to form the front water channel 121.

[0039] It should be noted that the outer water pipe 180 is usually welded to the top surface of the drill rod 191, thereby sealing the top side of the first groove 193 to prevent the diving knife from leaking during the water delivery process.

[0040] In this embodiment, because the drill rod 191 and the bucket tooth seat 192 usually need to be fixed to ensure that there is no relative movement between the two, the specific fixing method can be welding, clamping, etc. In addition, because the front water channel 121 and the rear water channel 122 are not completely aligned, in order to ensure that the spray water flows stably between the two, a reserved hole 194 can be formed between the drill rod 191 and the bucket tooth seat 192, and the reserved hole 194 is connected between the front water channel 121 and the rear water channel 122.

[0041] refer to Figure 1 and Figure 2 In order to prevent the opening of the front water channel 121 from having a significant negative impact on the self-strength and internal stress distribution of the vibration output part 190, the front water channel 121 can be opened at the top of the drill rod 191.

[0042] It should be noted that the top of the drill rod 191 refers to the position of the drill rod 191 away from the ground in the vertical direction in the working state. At the same time, the front water channel 121 can be located in the middle position of the vibration output part 190 in the horizontal direction to prevent the physical structures on the upper and lower sides of the front water channel 121 from being unevenly stressed.

[0043] Similarly, in order to prevent the opening of the rear water channel 122 from having a significant negative impact on the strength and internal stress distribution of the bucket tooth seat 192, the rear water channel 122 can be opened at the top of the bucket tooth.

[0044] It should be noted that the top of the tooth seat 192 refers to the position of the tooth seat 192 away from the ground in the vertical direction when the tooth seat 192 is in the working state. At the same time, the rear water channel 122 can be located in the middle position of the tooth seat 192 in the horizontal direction to prevent the physical structures on both sides of the rear water channel 122 from being unevenly stressed.

[0045] Of course, in other embodiments of the utility model, on the premise of ensuring that the strength of the drill rod 191 and the bucket tooth seat 192 and the internal stress distribution meet the requirements of the excavation operation, the front water channel 121 can be opened in the middle or bottom of the drill rod 191, and the rear water channel 122 can be opened in the middle or bottom of the bucket tooth seat 192. There is no limitation on the specific opening positions of the front water channel 121 and the rear water channel 122.

[0046] In this embodiment, the front water channel 121 and the rear water channel 122 are both straight lines, which are easy to process. In other embodiments of the utility model, without affecting the water delivery effect, the front water channel 121 and the rear water channel 122 can also be in the form of a broken line or a curve, and there is no limitation on their specific extension shapes.

[0047] refer to Figure 1 and Figure 2 The water delivery structure 100 for the high-frequency breaker also includes a third nozzle 150 , which is disposed at the vibration output portion 190 , the third nozzle 150 is spaced apart from the first nozzle 130 , and an inlet of the third nozzle 150 is connected to an outlet of the first nozzle 130 .

[0048] It should be noted that the first nozzle 130 is arranged on the top side of the drill rod 191. By arranging the third nozzle 150, the first nozzle can be shielded and protected to prevent the first nozzle from being blocked by mud during the operation. In addition, because the third nozzle 150 is spaced apart from the first nozzle 130, during the crushing operation, rock debris is more likely to block the third nozzle 150. The third nozzle 150 can be directly unblocked using a tool so that the rock debris is discharged from the gap between the first nozzle 130 and the third nozzle 150.

[0049] Specifically, the first nozzle 130 and the third nozzle 150 are both inverted trumpet-shaped structures, and their inner diameters gradually decrease from the inlet to the outlet. Their inner walls can be inclined straight lines or arc-shaped; of course, the inner walls of the two can also be stepped to ensure that their inner diameters at the inlets are larger.

[0050] At the same time, the second nozzle 140 is arranged on the vibration output part 190 and is spaced apart from the output end of the inner waterway 120. It should be noted that the second nozzle 140 is arranged on the bucket tooth seat 192 and is spaced apart from the output end of the rear waterway 122. The second nozzle 140 can shield and protect the output end of the rear waterway 122 to prevent mud from clogging the rear waterway 122 during operation.

[0051] Specifically, the second nozzle 140 can be an inverted trumpet-shaped structure, whose inner diameter gradually decreases from the inlet to the outlet, and its inner wall can be an inclined straight line or an arc-shaped; of course, the inner wall of the second nozzle 140 can also be stepped to ensure that its inner diameter at the inlet is larger.

[0052] The water supply structure 100 for the high-frequency breaker can be used to pressurize the outflowing spray water by providing the first nozzle 130, the second nozzle 140 and the third nozzle 150, which can help prevent blockage on the one hand and improve the dust removal effect on the other hand.

[0053] refer to Figure 1 and Figure 2 In order to ensure that there is a safe distance between the output end of the rear water channel 122 and the source of dust generation, and to avoid clogging the output end of the rear water channel 122 at the moment of dust generation, the bucket tooth seat 192 can be provided with a second groove 195, and the output end of the rear water channel 122 can be opened on the groove wall of the second groove 195.

[0054] Similarly, in order to improve the protection effect and prevent the second nozzle 140 from colliding during the crushing operation, the second nozzle 140 can also be accommodated in the second groove 195.

[0055] In the present embodiment, the number of the second grooves 195 is two, and the two second grooves 195 are respectively formed on both sides of the top of the bucket tooth seat 192; of course, in other embodiments of the present invention, the number of the second grooves 195 can also be one, three, five, etc., and their setting positions can be at the bottom, the middle or the edge of the left and right parts of the bucket tooth seat 192. There is no limitation on the specific number and setting positions of the second grooves 195.

[0056] The embodiment of the utility model also provides a high-frequency breaker, including a hydraulic motor, an excitation box, a radiator and a water supply structure 100 for the high-frequency breaker, wherein the hydraulic motor is used to provide a power source to drive the eccentric gear in the excitation box to rotate and generate centrifugal force, so as to drive the vibration output part 190 to perform a crushing operation under the action of the centrifugal force. The radiator is arranged on the side of the excitation box to dissipate heat and cool the excitation box to avoid overheating of the excitation box. The radiator can specifically be a cooling fan or a water cooling box. In order to improve the utilization rate of cooling water, the water cooling box can be connected to the internal water supply pipeline and the external water supply pipeline, and then the cooling water can be used for spraying and dust removal.

[0057] An embodiment of the utility model also provides a tunneling equipment, including a high-frequency breaker, a walking carrier and a driving source. The walking carrier is used to drive the high-frequency breaker to move, so as to perform crushing operations at different positions, and the driving source is used to provide a power source to the walking carrier and the high-frequency breaker.

[0058] Specifically, the excavation equipment can be a tunneling machine and a rock drill, etc., which mainly performs crushing operations by contacting the soil layer or rock with a high-frequency breaker. The excavation equipment includes a high-frequency breaker, which has all the functions of a high-frequency breaker.

[0059] In summary, the water delivery structure 100 for a high-frequency breaker, the high-frequency breaker, and the excavation equipment provided by the embodiments of the present utility model have at least the following advantages:

[0060] (1) On the one hand, it can realize large-scale spraying of bucket teeth, and on the other hand, it can accurately spray the source of dust at the moment of dust generation, thereby slowing down the dispersion of dust;

[0061] (2) By limiting the location of the front water channel 121 and the rear water channel 122, the negative impact of the opening of the water channel on the strength and internal stress distribution of the drill rod 191 and the bucket tooth seat 192 can be reduced.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
