Description

Technical Field

[0001] This invention relates to the field of blade nozzle technology, specifically a blade nozzle for building construction. Background Technology

[0002] Drill bits are rock-breaking tools used in drilling engineering to break rocks and form wellbores. During drilling, in addition to the impact and breaking of rocks by the cutting edges, the impact of drilling fluid on the bottom of the well, the transport of cuttings, and the cooling of the drill bit head are also crucial factors. In modern drilling technology, in addition to requiring drill bits with excellent rock-breaking cutting structures, they also need good hydraulic properties for cleaning the bottom of the well, transporting cuttings, and cooling and cleaning the cutting teeth. In conventional drill bits, the main role of drilling fluid is to transport cuttings, clean the bottom of the well, and cool the cutting structures such as PDC teeth. Because conventional drill bits have fluid stagnation and eddy zones in their structure, the fluid velocity is slow in these areas. The formation of stagnation zones has an adverse effect on the drill bit and cutting teeth, hindering cuttings transport and bottom-of-well cleaning, as well as drill bit cooling. When facing soft formations such as sandstone layers, the drill bit cannot transport cuttings in a timely manner, leading to continuous accumulation of cuttings and ultimately drill bit failure. When facing hard rock formations such as granite, the cutting teeth cannot dissipate heat effectively, eventually leading to thermal failure. At the same time, the high-pressure impact of the fluid also fails to act effectively on the rock, thus failing to assist the drill bit in cutting.

[0003] When the blade nozzle is working, the soil it loosens will be smoothly discharged from the drilled channel after passing through the water sprayed from the nozzle. However, at the same time, mud clumps may be stuck on the outer wall of the nozzle, preventing the mud from being discharged. This forces the blade nozzle to stop working, affecting the drilling efficiency. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted in this invention is as follows:

[0006] A cutting blade nozzle for construction includes a drill bit module, a flushing module, and a water distribution module. The drill bit module includes a drill bit body, multiple main water holes on the top of the drill bit body, a main nozzle movably connected to the main water holes, multiple spray holes on the main nozzle, multiple cutting blades installed on the outside of the drill bit body, multiple teeth embedded on one side of the cutting blades, and multiple auxiliary water holes on the drill bit body. The flushing module includes multiple water guide plates surrounding the outside of the drill bit body, two auxiliary nozzles installed on both sides of the water guide plates, and circulating water plates installed on both sides of the cutting blades. Both sides of the water guide plates are machined into arc surfaces. The water distribution module includes a hydraulic cylinder installed inside the drill bit body, a disc body connected to the movable end of the hydraulic cylinder, a disc sleeve connected to the top of the disc body, multiple rubber sleeves installed on the top of the disc sleeve, multiple cylinder sleeves surrounding the outside of the disc sleeve, a spring embedded inside the cylinder sleeve, and a rubber plug connected to the outer end of the spring. The rubber plug slides through the outer end of the cylinder sleeve.

[0007] By adopting the above technical solution, when mud blocks appear in the discharge channel, the movable end of the hydraulic cylinder is extended, and then the disc body and disc sleeve rise. When the rubber sleeve at the top of the disc sleeve is on the outside of the main nozzle, the water in the drill bit body will only be sprayed out through multiple auxiliary nozzles. The water flow sprayed out by the auxiliary nozzles hits the circulating water plate along the outer wall of the discharge channel. The circulating water plate, together with the cutter blade, blocks the water back. Then the water comes into contact with the arc surface to realize the circulation of water. Then the mud blocks in the discharge channel are washed away, effectively ensuring the drilling speed of the drill bit body.

[0008] In a preferred embodiment, the present invention can be further configured such that: multiple nozzles are equally spaced and arranged in a ring, and the main nozzle is connected to the interior of the drill bit body through the multiple nozzles.

[0009] In a preferred embodiment, the present invention may be further configured such that the teeth are inclined and the multiple teeth are equally spaced and arranged in an arc.

[0010] In a preferred embodiment, the present invention can be further configured such that the water guide plate and the blade are arranged alternately, and a discharge channel is formed between the water guide plate and the blade.

[0011] In a preferred embodiment, the present invention can be further configured such that: multiple auxiliary water holes are located on the inner side of multiple water guide plates, and two auxiliary nozzles on the water guide plates are connected to the inside of the drill bit body through the auxiliary water holes on the inner side of the water guide plates.

[0012] In a preferred embodiment, the present invention can be further configured such that the diameter of the disc body is smaller than the inner diameter of the drill bit body, and the diameter of the disc sleeve is equal to the diameter of the disc body.

[0013] In a preferred embodiment, the present invention can be further configured such that: multiple rubber sleeves are respectively located at the bottom of multiple main water holes, and the diameter of the rubber sleeves is larger than the diameter of the main water holes.

[0014] In a preferred embodiment, the present invention can be further configured such that: a plurality of rubber plugs are located inside a plurality of secondary water holes, and the rubber plugs are interference-fitted with the secondary water holes.

[0015] In a preferred embodiment, the present invention can be further configured such that: a plurality of transmission plates are installed at the bottom of the main nozzle, the plurality of transmission plates are all located inside the drill bit body and are arranged in a ring with equal spacing, and the transmission plates are arranged alternately with the nozzle holes.

[0016] In a preferred embodiment, the present invention may be further configured such that: the disc body is provided with a drag reduction component, the drag reduction component includes a plurality of first openings opened on the disc body and a plurality of second openings opened on the disc sleeve, the plurality of first openings are equally spaced around the outside of the hydraulic cylinder, and the plurality of second openings are respectively located on the top of the plurality of hydraulic cylinders.

[0017] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0018] 1. In this invention, when mud blocks appear in the discharge channel, the movable end of the hydraulic cylinder is extended, and then the disc body and disc sleeve rise. When the rubber sleeve at the top of the disc sleeve is on the outside of the main nozzle, the water in the drill bit body will only be sprayed out through multiple auxiliary nozzles. The water flow sprayed out by the auxiliary nozzles hits the circulating water plate along the outer wall of the discharge channel. The circulating water plate, together with the cutter blade, blocks the water back. Then the water comes into contact with the arc surface to realize the circulation of water. Then the mud blocks in the discharge channel are washed away, effectively ensuring the drilling speed of the drill bit body.

[0019] 2. In this invention, when the rubber plug blocks the auxiliary water hole, the water in the drill bit body can only flow out from the main water hole, ensuring the water flow impact strength. Then, the drill bit body is controlled to drill into the ground. Then, when the drill bit body rotates with the cutter blades and teeth, the drill bit body advances to a deeper soil layer. Then, the loose soil that is drilled out is flushed out by the water sprayed from the main nozzle, so that the drill bit can work smoothly.

[0020] 3. In this invention, the water sprayed from either the main nozzle or the auxiliary nozzle will cool down the drill bit body, cutter blades, and teeth when impacting and loosening the soil, thereby reducing the damage caused by overheating and extending their service life.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0036] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0037] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a blade nozzle for building construction. Example

[0038] Combination Figures 1-8As shown, the present invention provides a blade nozzle for building construction, including a drill bit module 100, a flushing module 200 and a water distribution module 300. The drill bit module 100 includes a drill bit body 110, a plurality of main water holes 120 opened on the top of the drill bit body 110, a main nozzle 130 movably connected to the main water holes 120, a plurality of spray holes 140 opened on the main nozzle 130, a plurality of blades 150 installed on the outside of the drill bit body 110, a plurality of teeth 160 embedded on one side of the blades 150, and a plurality of auxiliary water holes 170 opened on the drill bit body 110.

[0039] The flushing module 200 includes multiple water guide plates 210 surrounding the outside of the drill bit body 110, two auxiliary nozzles 230 installed on both sides of the water guide plates 210, and circulating water plates 240 installed on both sides of the cutter blade 150. Both sides of the water guide plates 210 are processed into arc surfaces 220.

[0040] The water distribution module 300 includes a hydraulic cylinder 310 installed inside the drill bit body 110, a disc body 320 connected to the movable end of the hydraulic cylinder 310, a disc sleeve 330 connected to the top of the disc body 320, a plurality of rubber sleeves 340 installed on the top of the disc sleeve 330, a plurality of cylinder sleeves 350 surrounding the outside of the disc sleeve 330, a spring 360 embedded inside the cylinder sleeve 350, and a rubber plug 370 connected to the outer end of the spring 360, wherein the rubber plug 370 slides through the outer end of the cylinder sleeve 350.

[0041] Furthermore, the multiple nozzles 140 are evenly spaced and arranged in a ring. The main nozzle 130 is connected to the inside of the drill bit body 110 through the multiple nozzles 140. This layout design ensures that the water inside the drill bit body 110 can be sprayed out from the multiple main nozzles 130, providing conditions for flushing away loose soil.

[0042] Furthermore, the tooth 160 is inclined, and multiple teeth 160 are evenly spaced and arranged in an arc. This layout design improves the ability of the blade 150 to break up the soil layer and, to a certain extent, increases the drilling speed of the drill bit body 110.

[0043] Furthermore, the water guide plate 210 and the blade 150 are arranged alternately, and a discharge channel is formed between the water guide plate 210 and the blade 150. The discharge channel is set to ensure that the mud can be discharged from the drilling channel.

[0044] Furthermore, multiple auxiliary water holes 170 are located inside multiple water guide plates 210. The two auxiliary nozzles 230 on the water guide plate 210 are connected to the inside of the drill body 110 through the auxiliary water holes 170 inside the water guide plate 210. This structural design ensures that the auxiliary nozzles 230 can spray water.

[0045] Furthermore, the diameter of the disc body 320 is smaller than the inner diameter of the drill bit body 110, and the diameter of the disc sleeve 330 is equal to the diameter of the disc body 320. This size design ensures that the water flow inside the drill bit body 110 can flow to the main water hole 120 and the auxiliary water hole 170.

[0046] Furthermore, multiple rubber sleeves 340 are located at the bottom of multiple main water holes 120. The diameter of the rubber sleeves 340 is larger than the diameter of the main water holes 120. With this size design, after the rubber sleeves 340 are put on the outside of the main water holes 120, water can be completely blocked outside the main water holes 120.

[0047] Furthermore, multiple rubber plugs 370 are located inside multiple auxiliary water holes 170 respectively. The rubber plugs 370 are interference-fitted with the auxiliary water holes 170. With this structural design, when the main nozzle 130 sprays water, the rubber plugs 370 can block the auxiliary water holes 170 to ensure the water spray force of the main nozzle 130. Example

[0048] Combination Figure 4 As shown, based on Embodiment 1, multiple transmission plates 400 are installed at the bottom of the main nozzle 130. The multiple transmission plates 400 are all located inside the drill bit body 110 and are arranged in a ring with equal spacing. The transmission plates 400 are staggered with the spray holes 140. When water flows towards the main nozzle 130, the transmission plates 400 will rotate the main nozzle 130, thereby improving the efficiency of loosening soil discharge. Example

[0049] Combination Figures 6-8 As shown, in the above embodiment, the disc body 320 is provided with a drag reduction component 500. The drag reduction component 500 includes a plurality of first openings 510 opened on the disc body 320 and a plurality of second openings 520 opened on the disc sleeve 330. The plurality of first openings 510 are equally spaced around the outside of the hydraulic cylinder 310, and the plurality of second openings 520 are respectively located on the top of the plurality of hydraulic cylinders 310. With the drag reduction component 500 provided, water in the drill bit body 110 can flow from the first openings 510 and the second openings 520 to the main water hole 120, reducing the resistance when the water flows.

[0050] The working principle and usage process of this invention are as follows: In the initial state, the rubber plug 370 blocks the auxiliary water hole 170, allowing water inside the drill bit body 110 to flow out only from the main water hole 120, ensuring the water flow impact strength. When the device is put into actual use, the drill bit body 110 has already drilled into the ground. As the drill bit body 110 rotates with the cutter blades 150 and teeth 160, it advances into deeper soil layers. The loose soil that is drilled out is discharged from the discharge channel along with the water flow when water is sprayed from the main nozzle 130. Simultaneously, the water sprayed from the main nozzle 130 also reduces the temperature of the drill bit body 110, cutter blades 150, and teeth 160. The system ensures stable operation of all three components. When mud blocks appear in the discharge channel, the movable end of the hydraulic cylinder 310 is extended, causing the disc body 320 and disc sleeve 330 to rise. When the rubber sleeve 340 at the top of the disc sleeve 330 is placed outside the main nozzle 130, the water inside the drill bit body 110 will only be sprayed out through multiple auxiliary nozzles 230. The water sprayed out by the auxiliary nozzles 230 will collide with the circulating water plate 240 along the outer wall of the discharge channel. The circulating water plate 240, in conjunction with the cutter wing 150, will block the water back. Then, the water will come into contact with the arc surface 220, achieving water circulation. The mud blocks in the discharge channel will then be flushed away, effectively ensuring the drilling speed of the drill bit body 110.

[0051] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
