Abstract
Description
Technical Field
[0001] This application relates to the field of dust treatment equipment technology, and in particular to a dust treatment device for water source drilling rigs. Background Technology
[0002] Water source drilling rigs are engineering machines specifically designed for drilling water wells and exploring groundwater resources. They are widely used in agricultural irrigation, domestic water supply, geothermal development, and coalbed methane extraction, and can achieve efficient and safe drilling operations in clay, sand, gravel, and even medium-hard rock formations. However, during the high-speed rotary drilling process, existing water source drilling rigs generate a large amount of debris, dust, and other materials in the borehole due to the friction and shearing between the drill bit and the geological strata. These materials fly out of the borehole along with the drill rod, causing serious dust pollution in the water source drilling rig's operating environment and seriously harming the health of the workers. In addition, the reduced visibility affects the progress of the drilling operation and poses a huge safety hazard, with poor stability and reliability.
[0003] Therefore, there is an urgent need for a dust treatment device for water source drilling rigs to solve the defects of existing water source drilling rigs in actual operation. Summary of the Invention
[0004] This application proposes a dust treatment device for water source drilling rigs, which effectively reduces the amount of debris and dust generated during drilling, resulting in lower environmental pollution and a better ecological environment during drilling. This addresses the problem that existing water source drilling rigs, during high-speed rotary drilling, generate large amounts of debris and dust within the borehole due to friction and shearing between the drill bit and the geological strata. This dust is then ejected from the borehole along with the drill rod, causing severe dust pollution in the drilling environment, seriously harming the health of workers, reducing visibility, affecting the progress of drilling operations, and posing significant safety hazards.
[0005] To achieve the above objectives, this application adopts the following technical solution: a dust treatment device for a water source drilling rig, comprising a sleeve structure anchored to the drilling point by a screw, and a filter assembly for filtering debris, dust, and other substances is provided at the top of the inner cavity of the sleeve structure. The outer curved surface of the filter assembly is fixedly connected to the inner wall of the sleeve structure through a positioning ring. A vibration assembly is movably sleeved at the top of the inner cavity of the sleeve structure and above the filter assembly, so that the drill rod of the water source drilling rig passes through the vibration assembly and rotates downward to perform drilling operations. The vibration assembly includes a linkage collar whose bottom end is movably sleeved at the top of the inner cavity of the sleeve structure. The linkage collar has three sets of ring-shaped arrays arranged inside. The filter assembly has a through groove, and a power pressure block is slidably connected inside the through groove. The power pressure block has a vertically penetrating wedge-shaped groove inside, and a linkage pressure block is slidably connected inside the wedge-shaped groove. The top of the linkage pressure block has a second elastic connecting rod that forms a transmission connection with the linkage collar. Under the elastic force of the second elastic connecting rod, the linkage pressure block can always maintain an upward movement trend. The bottom of the linkage pressure block is fixedly installed with a clamping plate that contacts the filter screen assembly. When the linkage collar rotates with the drill rod, the power pressure block and the clamping plate can force the filter screen assembly to vibrate and shake off the debris, dust and other substances filtered on it, thereby preventing clogging.
[0006] Furthermore, the filter assembly includes a filter screen fixedly mounted on the inner side of the sleeve structure, and an elastic ring fixedly mounted on the outer side of the filter screen. The elastic ring is fixedly mounted on the inner wall of the sleeve structure by a positioning ring, thereby giving the filter screen a certain elasticity and making it less prone to tearing damage when it is squeezed and floats up and down.
[0007] Furthermore, the inner end of the power block is designed with an upwardly inclined bevel structure, and a slider assembly is slidably connected to the inner side of the positioning ring. A first elastic connecting rod is fixedly installed on the inner wall of the slider assembly and is connected to the outer end of the power block for transmission. Initially, under the elastic force of the first elastic connecting rod, the inner end of the power block extends out of the inner wall of the linkage collar. Then, when the drill rod on the water source drilling rig passes through the linkage collar, the bevel structure at the inner end of the power block forces the power block to move outward and compress the first elastic connecting rod, thereby ensuring the transmission connection strength between the linkage collar and the drill rod and preventing slippage.
[0008] Furthermore, the top of the inner side of the linkage pressure block is provided with an inclined surface that cooperates with the wedge-shaped surface of the power pressure block. When the power pressure block moves outward under the pressure of the drill rod, the linkage pressure block is forced to move downward and squeeze the filter screen assembly under the action of the wedge-shaped groove and the inclined surface, causing the filter screen on it to deform, thereby effectively increasing the vibration amplitude of the filter screen to shake off the debris, dust and other substances filtered on it.
[0009] Furthermore, a clamping plate is fixedly installed at the bottom end of the linkage pressure block, and a pressure roller with its outer surface in contact with the top of the filter screen is slidably sleeved at the bottom end of the clamping plate. Thus, when it comes into contact with the filter screen, the frictional damage caused by the linkage pressure block to the filter screen can be effectively reduced by rolling friction contact.
[0010] Furthermore, the inner diameter of the top of the sleeve structure is the same as the diameter of the drill rod of the water source drilling rig, and an outwardly expanding chamber structure is provided in the middle of the sleeve structure to store debris, dust and other substances shaken off from the filter screen.
[0011] The beneficial effects of this invention are as follows: 1. The dust treatment device for water source drilling rig provided in this application can be configured with an elastic filter structure at the top of the inner cavity of the sleeve structure for the filter screen assembly and vibration assembly, thereby filtering out the debris, dust and other substances generated during the drilling process of the water source drilling rig, so as to reduce the degree of environmental pollution during the drilling process, and make the ecological environment during the drilling process better, with higher stability and reliability.
[0012] 2. The dust treatment device for water source drilling rig provided in this application, with the setting of the vibration component and its structure, when the linkage collar rotates with the drill rod, under the action of the power pressure block and the clamping plate, can force the filter screen to vibrate and shake off the debris, dust and other substances filtered on it, effectively preventing the phenomenon of clogging, thereby effectively improving the stability and reliability of the device during operation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] like Figure 1 As shown, a dust treatment device for a water source drilling rig includes a sleeve structure 1 anchored to the drilling point by a screw. A filter assembly 2 for filtering debris, dust, and other substances is provided at the top of the inner cavity of the sleeve structure 1. The outer curved surface of the filter assembly 2 is fixedly connected to the inner wall of the sleeve structure 1 via a positioning ring 3. A vibration assembly 4 is movably sleeved at the top of the inner cavity of the sleeve structure 1, above the filter assembly 2, causing the drill rod of the water source drilling rig to pass through the vibration assembly 4 and rotate downwards for drilling operations. Figure 3 , Figure 5 as well as Figure 6 As shown, the vibration assembly 4 includes a linkage collar 9 whose bottom end is movably sleeved on the top of the inner cavity of the sleeve structure 1. The linkage collar 9 has three sets of through slots arranged in a ring array inside, and a power pressure block 10 is slidably connected inside the through slots. The power pressure block 10 has a wedge-shaped groove 11 that runs vertically through it, and a linkage pressure block 12 is slidably connected inside the wedge-shaped groove 11. The top of the linkage pressure block 12 is provided with a second elastic connecting rod 13, which forms a transmission connection with the linkage collar 9. Under the elastic force of the second elastic connecting rod 13, the linkage pressure block 12 can always maintain an upward movement trend. The bottom end of the linkage pressure block 12 is fixedly installed with a clamping plate 15 that contacts the filter assembly 2. When the linkage collar 9 rotates with the drill rod, under the action of the power pressure block 10 and the clamping plate 15, the filter assembly 2 can be forced to vibrate and shake off the debris, dust and other substances filtered on it, thereby preventing clogging.
[0017] like Figure 1 , Figure 2As shown, in this technical solution, the filter assembly 2 includes a filter screen 7 fixedly installed on the inner side of the sleeve structure 1, and an elastic ring 8 fixedly installed on the outer side of the filter screen 7. The elastic ring 8 is fixedly installed on the inner wall of the sleeve structure 1 through the positioning ring 3, so that the filter screen 7 has a certain elasticity and is not easily pulled and damaged when it is squeezed and floats up and down.
[0018] like Figures 1-4 As shown, in this technical solution, the inner end of the power block 10 is designed with an upwardly inclined bevel structure, and a slider assembly 5 is slidably connected to the inner side of the positioning ring 3. A first elastic connecting rod 6 is fixedly installed on the inner wall of the slider assembly 5 and is connected to the outer end of the power block 10. Initially, under the elastic force of the first elastic connecting rod 6, the inner end of the power block 10 extends out of the inner wall of the linkage collar 9. When the drill rod on the water source drilling rig passes through the linkage collar 9, under the action of the bevel structure at the inner end of the power block 10, the power block 10 can be forced to move outward and compress the first elastic connecting rod 6 to ensure the transmission connection strength between the linkage collar 9 and the drill rod, so that slippage is not likely to occur between them.
[0019] like Figure 3 , Figure 5 as well as Figure 6 As shown, in this technical solution, the top of the inner side of the linkage pressure block 12 is provided with an inclined surface 14 that cooperates with the wedge-shaped surface of the power pressure block 10. When the power pressure block 10 moves outward under the pressure of the drill rod, the linkage pressure block 12 is forced to move downward and squeeze the filter screen assembly 2 under the action of the wedge-shaped groove 11 and the inclined surface 14, causing the filter screen 7 on it to deform, thereby effectively increasing the vibration amplitude of the filter screen 7 to shake off the debris, dust and other substances filtered on it.
[0020] like Figure 3 , Figure 6 As shown, in this technical solution, a clamping plate 15 is fixedly installed at the bottom end of the linkage pressure block 12, and a pressure roller 16 whose outer surface contacts the top of the filter screen 7 is slidably sleeved at the bottom end of the clamping plate 15. Thus, when it comes into contact with the filter screen 7, the frictional damage caused by the linkage pressure block 12 to the filter screen 7 can be effectively reduced by rolling friction contact.
[0021] In this technical solution, the inner diameter of the top of the inner cavity of the sleeve structure 1 is the same as the diameter of the drill rod of the water source drilling machine, and an outwardly expanding chamber structure is provided in the middle of the inner cavity of the sleeve structure 1 to store the debris, dust and other substances shaken off from the filter screen 7.
