Description

Technical Field

[0001] This utility model specifically relates to a sealed dust collector for drilling, belonging to the field of drilling technology. Background Technology

[0002] Dust generated during drilling occurs when tools and materials rub and break at high speeds during the drilling process, causing fine particles to detach from the parent material and form dust. This dust pollutes the air and harms the respiratory health of operators.

[0003] However, existing sealing devices typically employ a fixed design, which reveals significant drawbacks in long-hole drilling. When the drill rod needs to continue penetrating deeper into the hole, the fixed sealing structure creates a rigid obstacle: its relative position to the drill rod remains unchanged, directly limiting the axial displacement space of the drill rod. As drilling progresses, it will come into hard contact with the fixed sealing device, preventing the drill rod from advancing further and thus fundamentally limiting the drilling depth.

[0004] To address this problem, this application proposes a sealed dust collector for drilling. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a sealed dust collector for drilling. The motor is mounted on one side of the feed cylinder. During drilling, the wall-supporting cylinder abuts against the wall, and the drill rod is sealed within it. Pushing the feed cylinder causes the rotating drill rod to screw into the wall. With the support of the wall-supporting cylinder, the feed cylinder pushes the corrugated telescopic tube to compress, ensuring continuous advancement of the drill rod and avoiding the limitations of fixed designs. At the same time, during advancement, the support rod guides and the support block provides support. The long spring in the spring cavity is compressed and stores energy, providing a reverse force to help the feed cylinder reset during operation retraction, thus solving the problems mentioned in the background art.

[0006] A sealed dust collector for drilling, comprising:

[0007] A sealing structure includes a propulsion cylinder, the front end of which is connected to a wall-supporting cylinder via a corrugated telescopic tube, and the rear end of which is equipped with three sets of support rods. A spring cavity corresponding to the position of the three sets of support rods is opened inside the propulsion cylinder, and a long spring is provided inside the spring cavity. The rear end of the support rod passes through the spring cavity and is connected to a support block.

[0008] The atomizing dust removal mechanism includes an atomizing nozzle installed inside the upper part of the wall-supporting cylinder for spraying water mist to remove dust, and a drain pipe is installed below the wall-supporting cylinder.

[0009] In a preferred embodiment, a rubber ring is installed at the front end of the wall-supporting cylinder.

[0010] In a preferred embodiment, the support block is fixedly connected to the front end of the long spring, and the rear end of the long spring is fixedly connected to the inner wall of the spring cavity.

[0011] In a preferred embodiment, a water trough is provided at the bottom of the wall-supporting cylinder, and the water trough is connected to a sewage pipe.

[0012] In a preferred embodiment, a water inlet pipe is installed above the wall-supporting cylinder, and the water inlet pipe is connected to the atomizing nozzle.

[0013] In a preferred embodiment, a set of grips is installed on each side of the propulsion cylinder, and the two sets of grips are arranged in a mirror-symmetrical manner.

[0014] In a preferred embodiment, a support bearing is provided in the middle of the inside of the propulsion cylinder, and the support bearing is fixedly connected to the inner wall of the propulsion cylinder by connecting rods around its perimeter.

[0015] As a preferred embodiment, a motor mounting ring is installed on one side of the propulsion cylinder, and multiple sets of screw holes are provided around the motor mounting ring.

[0016] Beneficial effects:

[0017] 1. By designing a sealed structure, the drill rod motor is installed on one side of the feed cylinder. During drilling, the wall-supporting cylinder first presses against the wall, sealing the drill rod inside the wall-supporting cylinder. Then, the feed cylinder is pushed, allowing the rotating drill rod to screw into the wall for drilling. At this time, under the support of the wall-supporting cylinder, the feed cylinder will push the corrugated telescopic tube to compress, ensuring that the drill rod can continue to advance forward. This effectively avoids the problem of fixed design in existing technologies that restricts drilling operations. Moreover, during the advance of the feed cylinder, under the guidance of the support rod and the support of the support block, the long spring in the spring cavity will be compressed. The compressed spring stores elastic potential energy, which can provide a reverse force when the operation is withdrawn, helping the feed cylinder to return to its original position.

[0018] 2. By designing an atomizing dust removal mechanism, it can play a highly efficient dust removal role during drilling operations: During the drilling process, the atomizing nozzle sprays water mist inside the wall-supporting cylinder, which can fully mix with the dust generated during drilling to achieve immediate dust reduction. The wastewater formed by the mixture of dust and water mist during the dust removal process will enter the water tank and eventually be discharged through the sewage pipe, avoiding dust leakage and environmental pollution.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 As shown, a sealed dust collector for drilling includes:

[0027] The sealing structure 1 includes a propulsion cylinder 11. The front end of the propulsion cylinder 11 is connected to a wall-supporting cylinder 14 through a corrugated telescopic tube 13. Three sets of support rods 15 are installed at the rear end of the wall-supporting cylinder 14. A spring cavity 110 corresponding to the position of the three sets of support rods 15 is opened in the propulsion cylinder 11, and a long spring 111 is provided in the spring cavity 110. The rear end of the support rod 15 passes through the spring cavity 110 and is connected to a support block 112.

[0028] The atomizing dust removal mechanism 2 includes an atomizing nozzle 24 installed inside the upper part of the wall-supporting cylinder 14 for spraying water mist to remove dust, and a drain pipe 21 is installed below the wall-supporting cylinder 14.

[0029] Please see Figure 2 , Figure 3 as well as Figure 5 As shown, a rubber ring 16 is installed at the front end of the wall-supporting cylinder 14. The rubber ring 16 can not only seal the gap between the wall-supporting cylinder 14 and the wall, but also increase the friction.

[0030] Please see Figure 3 As shown, the support block 112 is fixedly connected to the front end of the long spring 111, and the rear end of the long spring 111 is fixedly connected to the inner wall of the spring cavity 110.

[0031] Please see Figure 2As shown, a water tank 23 is provided at the bottom of the wall-supporting cylinder 14, and the water tank 23 is connected to the sewage pipe 21. The water tank 23 can collect the sewage generated by dust removal and discharge the sewage into the sewage pipe 21.

[0032] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, a water inlet pipe 22 is installed above the wall-supporting cylinder 14, and the water inlet pipe 22 is connected to the atomizing nozzle 24. The water inlet pipe 22 can be connected to a water pump to supply water to the atomizing nozzle 24, thereby achieving water mist dust removal.

[0033] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, a set of handles 12 are installed on each side of the propulsion cylinder 11, and the two sets of handles 12 are set in a mirror image. The handles 12 are convenient for operators to hold and facilitate pushing the propulsion cylinder 11 to perform drilling operations.

[0034] Please see Figure 3 As shown, a support bearing 18 is provided in the middle of the inside of the feed cylinder 11, and the support bearing 18 is fixedly connected to the inner wall of the feed cylinder 11 by connecting rods 19 around its perimeter. The support bearing 18 can provide support for the drill rod and ensure the stability of the drill rod when it rotates to drill.

[0035] Please see Figure 1 As shown, a motor mounting ring 17 is installed on one side of the propulsion cylinder 11, and multiple sets of screw holes are opened around the motor mounting ring 17.

[0036] In practical use, the working principle of this utility model is as follows:

[0037] In use, the drill rod is inserted into the feed cylinder 11, passing inside the support bearing 18. The support bearing 18 provides support for the drill rod and can rotate with it. Then, by inserting screws into the screw holes, the drive motor of the drill rod is connected and fixed to one side of the feed cylinder 11 with the motor mounting ring 17. When drilling, the rubber ring 16 at the front end of the wall-supporting cylinder 14 first presses against the wall. The rubber ring 16 not only seals the gap between the wall-supporting cylinder 14 and the wall, but also increases friction, making the wall-supporting cylinder 14 less prone to slippage, thereby sealing the drill rod against the wall-supporting cylinder. Inside 14, push the handles 12 on both sides of the advance cylinder 11 to make the rotating drill rod screw into the wall for drilling. At this time, under the support of the wall-supporting cylinder 14, the advance cylinder 11 will push the corrugated telescopic tube 13 to compress, ensuring that the drill rod can continue to advance forward. During the advance of the advance cylinder 11, the wall-supporting cylinder 14 supports the long spring 111 through three sets of support rods 15 and support blocks 112, so that the long spring 111 is compressed in the spring cavity 110. The compressed spring stores elastic potential energy, which can provide a reverse force when the operation is withdrawn, helping the advance cylinder 11 to return to its original position.

[0038] Before drilling, the water inlet pipe 22 can be connected to the water pump, and water can be supplied to the atomizing nozzle 24 through the water inlet pipe 22. The atomizing nozzle 24 sprays water mist inside the wall-supporting cylinder 14, which fully mixes with the dust generated during drilling to achieve immediate dust suppression. The wastewater formed by the mixture of dust and water mist enters the water tank 23 at the bottom of the wall-supporting cylinder 14 and is finally discharged through the sewage pipe 21 to prevent dust from leaking out and polluting the environment.
