Description

Technical Field

[0001] The utility model relates to the field of bucket teeth, in particular to a bucket tooth tip, a bucket tooth, a high-frequency breaker and an engineering vehicle. Background Art

[0002] Bucket teeth are important components on equipment such as high-frequency breakers and are also vulnerable parts. They mainly consist of a tooth seat with an insertion part and a tooth tip with a slot, and the two are connected by a pin shaft. High-frequency breakers are generally used in open-air sites. During use, a large amount of dust will be generated. Generally, no dust removal measures are taken, but the dust is allowed to dissipate naturally. In some construction environments, dust control is required. At this time, independent spraying equipment such as a sprinkler or a spray truck is generally used to spray the construction site to achieve the purpose of dust reduction and dust removal.

[0003] If a high-frequency breaker is used for operation in a tunnel or other narrow or enclosed space, due to the narrow operation space and relatively enclosed environment, if a large amount of dust is not processed in time, it will not only affect the operation visibility and thus the work progress, but also increase the dust content in the environment and affect the physical health of the staff. Due to space limitations, it is also impossible to use independent spraying equipment such as a sprinkler or a spray truck to spray the construction site to achieve the purpose of dust reduction and dust removal. Summary of the Utility Model

[0004] In view of this, the utility model provides a bucket tooth tip, a bucket tooth, a high-frequency breaker and an engineering vehicle, aiming to enable the tooth tip to spray liquid outward to reduce and remove dust at the construction site.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] A bucket tooth tip, the rear end of the tooth tip body has a slot, and the tooth tip body also has a liquid outlet channel extending from the slot to the surface of the tooth tip body; the liquid outlet channel has at least one liquid inlet in the slot for introducing liquid, and the liquid outlet channel has at least one liquid outlet on the surface of the tooth tip body for spraying liquid.

[0007] In some optional embodiments, the spraying direction of at least one liquid outlet faces the left or right side of the tooth tip body.

[0008] In some optional embodiments, the shape of the liquid outlet is a slit shape.

[0009] In some optional embodiments, the liquid outlet is arranged in a guiding groove formed on the surface of the tooth tip body.

[0010] In some optional embodiments, the liquid outlet is arranged along the transition surface of the guiding groove.

[0011] In some alternative embodiments, the liquid outlet channel includes a liquid inlet portion extending forward from the liquid inlet and a liquid outlet portion extending inward from the liquid outlet. The liquid inlet portion and the liquid outlet portion meet inside the tip body, and the aperture of the liquid inlet portion is larger than that of the liquid outlet portion.

[0012] A bucket tooth includes a tooth base and a tip as described in the previous item.

[0013] In some alternative embodiments, the tooth base has grooves or channels to guide liquid into the slots or liquid outlet channels of the tip body.

[0014] A high-frequency breaker includes the bucket tooth as described above.

[0015] An engineering trolley for non-explosive excavation includes the high-frequency breaker as described above.

[0016] In summary, compared with the prior art, the present utility model has the following advantages and beneficial effects: The present utility model can supply liquid (such as water) to the front surface of the tip body (i.e., the surface of the tooth tip) through the liquid outlet channel and spray it outward to the working area, avoiding the generation of dust at the working area, or spraying it outward to form a droplet mist and combining with the dust in the air, so that the dust absorbs water and quickly falls to the ground, thereby reducing the dust in the air and achieving the effects of dust reduction and dust removal. In addition, since a large amount of heat is generated at the tooth tip of the tip body during operation, the sprayed liquid can also cool the tip body, thereby extending the service life of the tip body.

[0027] Embodiment 1

[0028] For ease of description, a spatial rectangular coordinate system shown in the drawings is introduced to explain the related structure of the embodiments of the present application. Among them, the direction shown by the X-axis is the front, the direction shown by the Y-axis is the left, and the direction shown by the Z-axis is the upper.

[0029] The existing tooth tip has a slot 11 at the rear end of its tooth tip body 1 for connecting with the tooth socket, and the front half of the tooth tip body 1 is the tooth edge part for percussion operation. Generally, guiding grooves 13 are provided on the left and right sides at the top of the tooth edge part. The guiding grooves 13 are recessed downward to form a transition surface to optimize the force on the tooth edge, reduce the resistance during percussion, and guide the rock debris to be discharged outwards.

[0030] As Figures 1 - 5 shown, a tooth tip of a bucket tooth described in an embodiment of the present application includes a tooth tip body 1.

[0031] To achieve the spraying function at the tooth tip, in the embodiment of the present application, a liquid outlet channel 12 extending from within the slot 11 to the front surface of the tooth tip body 1 is machined on the basis of the existing tooth tip body 1. The liquid outlet channel 12 has at least one liquid inlet 121 within the slot 11 for introducing liquid, and the liquid outlet channel 12 has at least one liquid outlet 122 on the surface of the tooth tip body 1 for spraying liquid.

[0032] The liquid (such as water) is supplied through the liquid outlet channel 12 to the front surface of the tooth tip body 1 (i.e., the tooth edge surface) and sprayed outward to the working area, avoiding dust generation at the working area, or sprayed outward to form a droplet mist and combine with the dust in the air, so that the dust absorbs water and quickly falls to the ground, thereby reducing the dust in the air and achieving the effect of dust reduction and dust removal. In addition, since a large amount of heat is generated at the tooth edge of the tooth tip body 1 during operation, the sprayed liquid can also cool the tooth tip body 1, thereby extending the service life of the tooth tip body 1.

[0033] To avoid clogging of the liquid outlet 122, the spraying direction of at least one liquid outlet 122 can be considered to be set towards the left or right side of the tooth tip body 1. In this way, when the tooth tip body 1 is used for impact operation, the liquid outlet 122 located on the side is not easily in contact with the soil, gravel, etc. during operation, so it is not easily blocked.

[0034] In addition, to avoid clogging of the liquid outlet 122, the liquid outlet 122 can also be considered to be arranged in the guiding groove 13, that is, one liquid outlet 122 can be arranged corresponding to each guiding groove 13. Since the guiding groove 13 is recessed downward, it is not easy for soil, gravel, etc. to enter the guiding groove 13 during the operation of the tooth tip. And because the guiding groove 13 has a transition surface, the soil, gravel, etc. entering this place are not easy to accumulate and will quickly disperse, so it is even less likely to block the liquid outlet 122 arranged there.

[0035] The shape of the liquid outlet 122 can also be designed as a slit shape to enhance the effect of forming a droplet mist. Moreover, the slit-shaped liquid outlet 122 can increase the spraying area of the droplet mist to enhance the effect of dust reduction and dust removal.

[0036] In addition, the liquid outlet 122 can also be arranged along the transition surface of the guiding groove 13 so that the liquid outlet 122 is not easily in direct contact with soil, gravel, etc. and cause blockage.

[0037] As Figure 5 shown, the liquid outlet channel 12 can be set to include an inlet part with a larger aperture extending forward from the liquid inlet 121 for a certain distance and an outlet part with a smaller aperture extending inward from the liquid outlet 122, and the inlet part and the outlet part meet inside the tooth tip body 1. The inlet part with a larger aperture can ensure the liquid inlet flow rate, while the outlet part with a smaller aperture can ensure the effect of forming a droplet mist by spraying.

[0038] Embodiment 2

[0039] This embodiment of the present application also introduces a bucket tooth, which includes a tooth base and the tooth tip described in Embodiment 1. The bucket tooth with the above tooth tip also has a spraying function, and can achieve the effects of dust reduction, dust removal and reducing the temperature of the bucket tooth while working.

[0040] A groove or channel can be opened on the tooth base that cooperates with the tooth tip body 1 to guide the liquid into the slot 11 or the liquid outlet channel 12 of the tooth tip body 1. For example, a pipe can be arranged in the groove or channel on the tooth base, and the liquid outlet end of the pipe can be located in the slot 11 of the tooth tip body 1, or can be hermetically connected to the liquid inlet 121 of the liquid outlet channel 12 by means of screwing, plugging, clamping, etc., and then the liquid can be guided from the liquid source to the slot 11 or the liquid outlet channel 12 of the tooth tip body 1 through the pipe. Or, the front end opening of the channel on the tooth base is communicated with the slot 11 of the tooth tip body 1, and the liquid can be injected into the rear end opening of the channel on the tooth base, so that the liquid can enter the slot 11 of the tooth tip body 1 through the channel on the tooth base.

[0041] Embodiment 3

[0042] This embodiment of the present application also introduces a high-frequency breaker, which includes the bucket tooth described in Embodiment 2. The high-frequency breaker with the above bucket tooth can spray liquid to achieve the effects of dust reduction, dust removal and reducing the temperature of the bucket tooth, so as to realize continuous operation for a long time, reduce the damage of dust to construction workers, and ensure a relatively safe and comfortable construction environment for construction workers.

[0043] Embodiment 4

[0044] This embodiment of the present application also introduces an engineering trolley for non-explosive excavation, which includes the high-frequency breaker described in Embodiment 3. When the engineering trolley with the above high-frequency breaker is working, it can spray liquid to achieve the functions of dust reduction and dust removal, effectively improve the construction environment and reduce dust diffusion.

[0045] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0046] The above preferred embodiments should not be regarded as limitations on the present invention. The protection scope of the present invention should be subject to the scope defined by the claims. For those of ordinary skill in the art of this technology, without departing from the spirit and scope of the present invention, several improvements and refinements can also be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
