Description

Technical Field

[0001] This utility model relates to the field of anchor drilling rig technology, and in particular to a dust removal device for anchor drilling rigs. Background Technology

[0002] In coal mining, the excavation and stabilization of roadways are crucial operational steps, which are typically accomplished using bolt drilling rigs. These rigs use rotating drill rods to penetrate deep into the rock or soil, creating insertion channels for the bolts and thus stabilizing the roadway. However, during the drilling process, the high-speed rotation of the drill rods throws out gravel and dust generated within the borehole. This ejected gravel and dust not only pollutes the working environment, reduces visibility, and increases safety hazards, but also poses a direct threat to the respiratory system and other health of the workers. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a dust removal device for anchor drilling rigs.

[0004] A dust removal device for an anchor drilling rig includes a drilling rig body and a dust collection hood. The drilling rig body includes a fixed base and a drill rod. The dust collection hood is fixedly connected to the fixed base. The drill rod rotatably passes through the center of the dust collection hood. The device also includes a filter screen, a slag collection box, a slag discharge channel, a rotating ring, and a sweeping block. The filter screen is located inside the dust collection hood, and an air extraction port is opened below the filter screen inside the dust collection hood. The slag collection box is fixedly connected to the fixed base and located outside the dust collection hood. The slag discharge channel passes through the dust collection hood, and the bottom of the slag discharge channel is inclined. The inlet of the slag discharge channel is connected to the drill rod through a bearing, and the outlet of the slag discharge channel is connected to the slag collection box. The filter screen is located between the outer wall of the bearing, the outer wall of the slag discharge channel, and the inner wall of the dust collection hood, and the upper surface of the filter screen is flush with the inlet of the slag discharge channel. The rotating ring is rotatably connected inside the bearing, and the sweeping block is fixed to the top of the rotating ring and located on the upper surface of the filter screen.

[0005] Furthermore, a drive motor is installed at the bottom of the dust collection hood, and a gear is fixedly connected to the output shaft of the drive motor. The lower part of the rotating ring has a gear ring that matches the gear, and the gear ring meshes with the gear.

[0006] Furthermore, an air pump is provided at the bottom of the dust collection hood, and the air inlet of the air pump is connected to the air extraction port through an air pipe.

[0007] Furthermore, the slag collection box has a slag discharge port on its side wall, and a baffle is rotatably connected inside the slag discharge port. The baffle is used to close or open the slag discharge port.

[0008] Furthermore, a wedge block is slidably connected to the slag collection box, a slot matching the wedge block is opened on the baffle, an elastic element is connected between the wedge block and the slag collection box, a pulling block is fixedly connected to the wedge block, and the pulling block is slidably connected to the slag collection box.

[0009] Furthermore, a protective shell is connected between the inner bottom of the dust collection hood and the bottom of the bearing, and the drive motor, the gear, and the gear ring are all located inside the protective shell.

[0010] Furthermore, the number of slag discharge channels is at least three, to ensure that at least one effective slag discharge channel is available whenever the dust collection hood is used at any tilt of the drilling rig body.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a dust collection hood to cover the dust and gravel generated during the drilling process, and uses a filter screen to separate the gravel and dust.

Detailed Implementation

[0018] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0019] Please see Figures 1-5 A dust removal device for an anchor drilling rig includes a drilling rig body and a dust collection hood 12. The drilling rig body includes a fixed base 101 and a drill rod 102. The dust collection hood 12 is fixedly connected to the fixed base 101. The drill rod 102 rotatably passes through the center of the dust collection hood 12. The device also includes a filter screen 13, a slag collection box 14, a slag discharge channel 15, a rotating ring 16, and a sweeping block 17. The filter screen 13 is installed inside the dust collection hood 12, and an air extraction port 121 is opened inside the dust collection hood 12 below the filter screen 13. The slag collection box 14 is fixedly connected to the fixed base 101 and is located within the dust collection hood. Externally, the slag discharge channel 15 passes through the dust collection hood 12. The bottom of the slag discharge channel 15 is inclined. The inlet of the slag discharge channel 15 is connected to the drill rod 102 through the bearing 18. The outlet of the slag discharge channel 15 is connected to the slag collection box 14. The filter screen 13 is located between the outer wall of the bearing 18, the outer wall of the slag discharge channel 15, and the inner wall of the dust collection hood 12. The upper surface of the filter screen 13 is flush with the inlet of the slag discharge channel 15. The rotating ring 16 is rotatably connected to the bearing 18. The sweeping block 17 is fixed to the top of the rotating ring 16 and located on the upper surface of the filter screen 13.

[0020] A drive motor 20 is installed at the bottom of the dust collection hood 12. A gear 21 is fixedly connected to the output shaft of the drive motor 20. The lower part of the rotating ring 16 has a gear ring 22 that matches the gear 21. The gear ring 22 meshes with the gear 21.

[0021] The bottom of the dust collection hood 12 is equipped with an air pump 30, and the air inlet of the air pump 30 is connected to the air extraction port 121 through an air pipe.

[0022] Because a large amount of dust will pass through the dust collection hood 12 when the device is working, in order to prevent this dust from affecting the normal operation of the drive motor 20 and the normal meshing of the gear 21 and the gear ring 22, a protective shell 60 is connected between the bottom of the dust collection hood 12 and the bottom of the bearing 18. The drive motor 20, gear 21 and gear ring 22 are all located inside the protective shell 60.

[0023] To ensure that at least one effective slag discharge channel 15 is available whenever the dust collection hood 12 is used at any tilt along with the drilling rig body, in this embodiment, the number of slag discharge channels 15 is three.

[0024] The working principle of this embodiment is as follows: During the drilling process, the drill rod 102 rotates and penetrates into the rock or soil. The dust and gravel generated are trapped inside the dust hood 12. At this time, the air pump 30 creates a negative pressure in the dust hood 12, and the filter screen 13 separates the gravel and dust. Because the gravel is large, it is not easy to pass through the filter screen 13, while the dust can pass through the pores of the filter screen 13. The dust is extracted from the air extraction port 121 and discharged to the outside through the air pipe for further treatment. In this way, dust can be effectively reduced.

[0025] In order to discharge the crushed stone, the drive motor 20 drives the gear 21 to rotate, thereby the meshing action of the gear 21 and the gear ring 22 causes the rotating ring 16 and the sweeping block 17 to rotate on the bearing 18. During the rotation, the edge of the sweeping block 17 will continuously sweep the upper surface of the filter screen 13. The crushed stone that stays on the filter screen 13 is swept off the slag discharge channel 15 by the sweeping block 17 and slides into the slag collection box 14 along the inclined surface of the inner bottom of the slag discharge channel 15.

[0026] Example 2: Based on Example 1, please refer to... Figures 1-5 A dust removal device for an anchor drilling rig, wherein a slag collection box 14 has a slag discharge port 141 on its side wall, and a baffle 40 is rotatably connected inside the slag discharge port 141, the baffle 40 being used to close or open the slag discharge port 141.

[0027] The slag collection box 14 has a sliding groove, and the inclined wedge block 50 is slidably connected in the sliding groove. The baffle 40 has a slot 401 that matches the inclined wedge block 50. An elastic element 51 is connected between the left side of the inclined wedge block 50 and the left side of the sliding groove. A pulling block 52 is fixedly connected to the inclined wedge block 50, and the pulling block 52 is slidably connected to the slag collection box 14.

[0028] The working principle of this embodiment is as follows: Initially, the wedge block 50 is engaged in the slot 401 under the elastic action of the elastic element 51, fixing the position of the baffle 40. When it is necessary to clean the gravel in the slag collection box 14, simply pull the pulling block 52 to the left, causing the wedge block 50 to move to the left and disengage from the slot 401. The elastic element 51 will be compressed, increasing the restoring force of the wedge block 50. Then, rotate and open the baffle 40, so that the slag discharge port 141 faces downward, and the gravel in the slag collection box 14 is naturally discharged by gravity. When it is necessary to lock the baffle 40... Simply rotate the baffle 40 toward the slag discharge port 141 to close it. During this process, the baffle 40 first contacts the inclined surface of the wedge block 50, and the inclined surface of the wedge block 50 generates a leftward pushing force on it, causing the wedge block 50 to retract into the groove. The elastic element 51 will be compressed, which increases the reset force of the wedge block 50. When the slot 401 of the baffle 40 is directly opposite the wedge block 50, the wedge block 50 is no longer subjected to the force from the baffle 40, and thus re-engages in the slot 401 under the elastic action of the elastic element 51, thereby locking the baffle 40.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
