Description

Technical Field

[0001] This utility model relates to the field of bucket tooth technology, specifically to a bucket tooth tip with spraying function, bucket teeth, and a high-frequency breaker. Background Technology

[0002] Bucket teeth are crucial components and wear parts in equipment such as high-frequency hydraulic breakers. They mainly consist of a tooth base with an insertion part and tooth tips with slots, connected by a pin. High-frequency hydraulic breakers are generally used in open-air environments, generating a large amount of dust during operation. Typically, dust suppression measures are not implemented, and the dust is allowed to dissipate naturally. However, some construction environments require dust control. In these cases, independent spraying equipment such as water trucks or sprinkler trucks is used to spray the work area to achieve dust suppression and removal.

[0003] If high-frequency hydraulic breakers are used in tunnels or other confined or enclosed spaces, the limited space and relatively enclosed environment mean that if a large amount of dust is not dealt with promptly, it will not only affect visibility and thus the work progress, but also increase the dust content in the environment, affecting the health of the workers. Due to space limitations, it is also impossible to use independent spraying equipment such as water trucks or sprinkler trucks to spray the construction site to achieve the purpose of dust suppression and removal.

[0004] For example, Chinese patent application CN119041520A describes a spraying bucket tooth that has a tooth base and a tooth tip, with a cover attached to the tooth tip. The liquid outlet channel in this bucket tooth is located in the front-middle part of the tooth tip body, and the front part of the tooth tip body (also called the tooth tip section) is the part in direct contact with the soil and rock, requiring high structural strength. Opening a channel in the front-middle part of the tooth tip body reduces the structural strength of that section, thus reducing its service life. Utility Model Content

[0005] In view of this, the present invention provides a bucket tooth tip with spraying function, a bucket tooth, and a high-frequency breaker, aiming to ensure that the tooth tip has spraying function while minimizing the impact of reduced tooth tip structural strength caused by opening channels.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is as follows:

[0007] A bucket tooth tip with a spraying function includes a tooth tip body, the rear end of which has a slot, and the tooth tip body also has a liquid outlet channel extending from the rear of the slot to the rear surface of the tooth tip body; it also includes a cover connected to the tooth tip body; the edge of the cover is provided with a spray port communicating with the liquid outlet channel.

[0008] In some alternative embodiments, the spray nozzle includes a front spray nozzle facing forward of the tooth tip body and a side spray nozzle facing the side of the tooth tip body.

[0009] In some alternative embodiments, the spray direction of the side spray nozzle is toward the rear side of the tooth tip body.

[0010] In some alternative embodiments, the front left and right sides of the cover have shielding portions extending to the rear, and the side spray nozzles are located to the rear of the shielding portions.

[0011] In some alternative embodiments, the cover extends from the rear to the front of the tooth tip body; the cover has a flow channel communicating with the liquid outlet channel, and the spray nozzle is located at the front of the cover and communicates with the flow channel.

[0012] A spraying bucket tooth includes a tooth base and tooth tips as described above; the tooth base has a liquid inlet channel extending from the rear to the front; the liquid inlet channel is connected to the liquid outlet channel.

[0013] In some optional embodiments, a sealing ring is also included; the sealing ring is disposed between the tooth base and the tooth tip and seals and fills the space between the liquid inlet channel and the liquid outlet channel; the sealing ring has a through hole to allow the liquid inlet channel and the liquid outlet channel to communicate with each other.

[0014] In some alternative embodiments, the tooth base and / or the tooth tip are provided with a groove, and the sealing ring is installed in the groove.

[0015] A high-frequency hydraulic breaker with a spraying function includes bucket teeth as described above.

[0016] In summary, compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model can provide protection for the drain outlet of the liquid outlet channel through a cover, preventing the drain outlet from directly contacting and being blocked by objects such as soil and gravel. Simultaneously, liquid (e.g., water) is supplied to the cover through the liquid outlet channel and sprayed outwards through the spray nozzles on the cover to form a water curtain or mist, which combines with dust in the air, causing the dust to absorb water and quickly fall to the ground, thereby reducing airborne dust. This utility model achieves the effect of dust reduction and removal through the combination of these various means.

[0017] Furthermore, the liquid sprayed out from the spray nozzle of the cover will also pour onto the tooth tip body to cool it down, preventing the tooth tip body from generating high temperatures due to prolonged operation and affecting its service life.

[0018] Meanwhile, by moving the liquid outlet channel from the front middle part of the tooth tip body to the rear part, the structure of the front half of the tooth tip body (i.e., the tooth tip part) is not damaged, thus having high structural strength, and its service life will not be affected by opening the liquid outlet channel.

[0019] Furthermore, changing the liquid outlet channel 22 from the front middle part of the tooth tip body 23 to the rear part can also prevent liquid leakage. This is because the tooth base 1 and the slot 21 at the rear of the tooth tip body 23 fit tightly together after assembly, with virtually no gap between them, so liquid cannot leak from the joint between the two.

[0033] Example 1

[0034] This application describes a bucket tooth tip with a spraying function, such as... Figure 1 and Figure 2 As shown, the tooth tip 2 includes a tooth tip body 23 and a cover member 3. For ease of description, an appendix is ​​introduced. Figure 1 The spatial rectangular coordinate system shown is used to illustrate the relevant structure of the embodiments of this application, wherein the positive direction of the X-axis is forward, the positive direction of the Y-axis is left, and the positive direction of the Z-axis is upward.

[0035] like Figure 5 and Figure 6 As shown, the rear end of the tooth tip body 23 has a slot 21 for connecting with the tooth base 1, and the front half of the tooth tip body 23 is the tooth tip for striking operations.

[0036] To achieve the spraying function of tooth tip 2, such as Figure 5 and Figure 6As shown, in this embodiment of the application, a liquid outlet channel 22 is machined on the tooth tip body 23, extending from the rear part inside the slot 21 to the rear surface of the tooth tip body 23. The liquid outlet channel 22 has at least one liquid supply port 221 in the slot 21 for supplying liquid, and at least one liquid outlet 222 on the surface of the tooth tip body 23 for discharging liquid.

[0037] Because the surface of the tooth tip 23 easily comes into direct contact with objects such as dirt and gravel during impact operations, these objects can easily clog the drain port 222, preventing liquid from being discharged from the tooth tip 23. To avoid this situation, such as... Figures 1-2 As shown, in this embodiment of the application, a cover 3 is connected to the tooth tip body 23. The cover 3 has a plurality of spray nozzles 32 that communicate with the liquid outlet channel 22. These spray nozzles 32 are preferably located on the edge of the cover 3.

[0038] In this embodiment, the cover 3 can be used to shield and protect the drain outlet 222 of the liquid outlet channel 22, preventing the drain outlet 222 from directly contacting and becoming blocked by objects such as soil and gravel. Simultaneously, liquid (e.g., water) is supplied to the cover 3 through the liquid outlet channel 22 and sprayed outwards through the spray nozzles 32 on the cover 3 to form a water curtain or mist, which combines with dust in the air. This causes the dust to absorb water and quickly fall to the ground, thereby reducing the amount of dust in the air. This embodiment achieves dust reduction and removal effects through a combination of these various methods.

[0039] Furthermore, the liquid sprayed outward from the spray nozzle 32 of the cover 3 will also spray the tooth tip body 23 to cool it down, preventing the tooth tip body 23 from being affected by high temperature due to long-term operation.

[0040] Meanwhile, by moving the liquid outlet channel 22 from the front middle part of the tooth tip body 23 to the rear part, the structure of the front half of the tooth tip body 23 (i.e., the tooth tip part) is not damaged, thus having high structural strength, and its service life will not be affected by opening the liquid outlet channel 22.

[0041] Furthermore, changing the liquid outlet channel 22 from the front middle part of the tooth tip body 23 to the rear part can also prevent liquid leakage. This is because the tooth base 1 and the slot 21 at the rear of the tooth tip body 23 fit tightly together after assembly, with virtually no gap between them, so liquid cannot leak from the joint between the two.

[0042] The spray nozzle 32 on the cover 3 can preferably be in the following form: such as Figure 7 and Figure 8As shown, at least one spray nozzle 32 sprays towards the front of the tooth tip body 23, and this spray nozzle 32 can be simply referred to as the front spray nozzle 321; and at least one spray nozzle 32 sprays towards the side of the tooth tip body 23, and this spray nozzle 32 can be simply referred to as the side spray nozzle 322. These spray nozzles 32 (i.e., the front spray nozzle 321 and the side spray nozzle 322) are also interconnected.

[0043] The advantages of this design are as follows: on the one hand, the liquid is sprayed forward to the work area through the spray nozzle 32 (i.e., front spray nozzle 321) on the front of the tooth tip body 23 via the spray direction on the cover 3, thus preventing dust from being generated at the work area; on the other hand, the liquid is sprayed to the side through the spray nozzle 32 (i.e., side spray nozzle 322) on the side of the tooth tip body 23 via the spray direction on the cover 3 to form a large area of ​​water curtain, blocking the spread of dust.

[0044] It should be noted that the specific spraying direction of the spray nozzles 32 (i.e., side spray nozzles 322) facing the side of the tooth tip body 23 includes facing directly to the side, to the front side, and to the rear side. However, the applicant discovered that when the spraying direction of these spray nozzles 32 faces the rear side of the tooth tip body 23, it also has the following advantages: if objects such as mud or gravel enter the spray nozzles 32 (i.e., front spray nozzles 321) on the cover 3 facing the front of the tooth tip body 23, these objects will be discharged outward with the liquid through the spray nozzles 32 (i.e., side spray nozzles 322) on the cover 3 facing the rear side of the tooth tip body 23, thus preventing them from accumulating in the cover 3 and causing blockage. Since the spray nozzles 32 that spray to the side and rear (i.e., side spray nozzles 322) have openings facing to the side and rear, objects such as soil and gravel cannot enter these side spray nozzles 322. Therefore, this embodiment of the application can ensure that at least some (or even all) of the spray nozzles 32 remain unobstructed, so that the entire tooth tip 2 can spray continuously and smoothly.

[0045] like Figure 1 As shown, the embodiments of this application can spray water simultaneously in the front, left rear, and right rear directions.

[0046] However, if the amount of soil, gravel, or other objects entering through the front-opening spray nozzle 32 (i.e., the front spray nozzle 321) is greater than the amount discharged through the rear-opening spray nozzle 32 (i.e., the side spray nozzle 322), the soil, gravel, or other objects cannot be discharged in time. As time goes on, the soil, gravel, or other objects may accumulate inside the cover 3, causing the spray nozzle 32 to become clogged.

[0047] At this time, such as Figure 7 and Figure 8As shown, the opening width of the spray nozzle 32 (i.e., the front spray nozzle 321) facing the front of the tooth tip body 23 can be designed to be smaller than the opening width of the spray nozzle 32 (i.e., the side spray nozzle 322) facing the rear of the tooth tip body 23. In this way, the amount of soil, gravel, and other objects entering through the front spray nozzle 32 (i.e., the front spray nozzle 321) will always be less than the amount discharged through the rear spray nozzle 32 (i.e., the side spray nozzle 322), allowing the soil, gravel, and other objects to be discharged in a timely manner, and keeping the spray nozzle 32 unobstructed at all times.

[0048] In addition, such as Figure 7 and Figure 8 As shown, the left and right sides of the front part of the cover 3 can also be designed with blocking portions 33 extending to the rear. The spray nozzle 32 (i.e., the side spray nozzle 322) facing the rear of the tooth tip body 23 is located on the rear side of the blocking portion 33. The blocking portion 33 can prevent objects such as soil and gravel from entering the rear side opening of the spray nozzle 32 (i.e., the side spray nozzle 322), protecting it from clogging.

[0049] As an optional implementation method, such as Figure 1 and Figure 2 As shown, the cover 3 is connected to the surface of the tooth tip body 23 and extends from the rear to the front of the tooth tip body 23. The cover 3 covers the drain port 222 of the liquid outlet channel 22 located on the rear surface of the tooth tip body 23. The cover 3 has a guide channel 31 that communicates with the drain port 222 of the liquid outlet channel 22, and the spray nozzle 32 is connected to the guide channel 31. Liquid (e.g., water) can then flow through the liquid outlet channel 22 and the guide channel 31 to the spray nozzle 32 and be sprayed outwards.

[0050] In the embodiments of this application, such as Figure 5 and Figure 6 As shown, the liquid outlet channel 22 extends from the rear part inside the slot 21 to the surface of the rear part of the tooth tip body 23, and the liquid outlet channel 22 may have one or more drain ports 222 on the surface of the tooth tip body 23. Figure 7 and Figure 8 As shown, the cover 3 is preferably a plate-shaped structure. The flow channel 31 can be provided on the side of the cover 3 that is connected to the tooth tip body 23, and the multiple spray nozzles 32 can be provided at the front of the cover 3. Liquid (e.g., water) can be supplied to the front end of the cover 3 through the liquid outlet channel 22 and the flow channel 31 and sprayed in different directions through the multiple spray nozzles 32.

[0051] In addition, such as Figure 7 and Figure 8As shown, a chamfer 34 can also be machined on the front of the cover 3 so that the cover 3 can smoothly enter the soil and rocks along with the tooth tip 2, avoiding excessive impact from the soil and rocks on the cover 3 during the entry process, which would cause the cover 3 to fall off.

[0052] Example 2

[0053] This application describes a bucket tooth with a spraying function, such as... Figure 1 and Figure 2 As shown, the bucket tooth includes a tooth base 1 and a tooth tip 2 as described in Embodiment 1.

[0054] To facilitate the supply of liquid to tooth tip 2, such as Figure 3 and Figure 4 As shown, an inlet channel 11 extending from the rear to the front can be opened on the tooth base 1, and the inlet channel 11 is connected to the outlet channel 22 of the tooth tip 2.

[0055] For example, the inlet channel 11 may have at least one inlet 111 at the rear of the tooth base 1 for introducing liquid, and at least one outlet 112 on the front surface of the tooth base 1 for introducing liquid into the outlet channel 22 of the tooth tip 2. It should be noted that the number of outlets 112 of the inlet channel 11 on the tooth base 1 must be consistent with the number of supply ports 221 of the outlet channel 22 on the tooth tip body 23, and the outlets 112 and supply ports 221 must be arranged in a one-to-one correspondence so that liquid can smoothly enter the outlet channel 22 on the tooth tip body 23 from the inlet channel 11 on the tooth base 1, thereby reducing the occurrence of liquid leakage.

[0056] Since there may be a gap between the tooth base 1 and the tooth tip 2 during assembly or operation, in order to prevent liquid leakage between the liquid inlet channel 11 on the tooth base 1 and the liquid outlet channel 22 on the tooth tip body 23, as an optional implementation, such as... Figure 2 As shown in the embodiment of this application, the bucket teeth may further include a sealing ring 4. The sealing ring 4 is disposed between the tooth base 1 and the tooth tip 2 and seals the space between the liquid inlet channel 11 and the liquid outlet channel 22. The sealing ring 4 has a through hole to allow the liquid inlet channel 11 and the liquid outlet channel 22 to communicate with each other. The sealing ring 4 may be made of flexible rubber material, possessing good elasticity, and can tightly fill the space between the liquid outlet 112 of the liquid inlet channel 11 and the liquid supply port 221 of the liquid outlet channel 22, preventing liquid leakage from this location.

[0057] Grooves can be pre-machined at the outlet 112 of the liquid inlet channel 11 on the tooth base 1 and / or the supply port 221 of the liquid outlet channel 22 on the tooth tip body 23 so that the sealing ring 4 can be installed in the groove. The advantage of this design is that it can prevent the sealing ring 4 from shifting during the assembly or operation of the bucket teeth, thereby ensuring the sealing effect.

[0058] The bucket teeth described in this application embodiment have a spraying function, which can achieve the effects of dust reduction, dust removal, and temperature reduction of the bucket teeth during operation.

[0059] Example 3

[0060] This application embodiment introduces a high-frequency breaker with a spraying function. When the high-frequency breaker with the above-mentioned bucket teeth is working, it can spray liquid to achieve the function of dust reduction and dust removal, which can effectively improve the construction environment and reduce dust diffusion.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
