Abstract
Description
Technical Field
[0001] This utility model relates to the field of rock drilling rig technology, and more specifically, to an underground rock drilling rig equipped with a multi-stage dust collection mechanism. Background Technology
[0002] In the fields of mineral resource extraction and underground engineering operations, the underground rock drilling rig is the core tunneling equipment. During the process of the drill bit rotating at high speed to break rocks, it will generate a large number of dust particles of different sizes. These dust particles not only permeate the working space, reducing visibility and accelerating the wear of mechanical parts, but more seriously, long-term inhalation of high concentrations of rock dust can cause occupational diseases such as pneumoconiosis, endangering the life and health of operators.
[0003] Traditional rock drilling rigs generate a large amount of dust when drilling into the rock wall. However, the drilling mechanism of traditional rock drilling rigs is generally not equipped with an effective dust collection system, making it difficult to extract and filter the dust generated during drilling operations in a timely manner. Although the existing rock drilling mechanism uses a multi-layer screening and collection scheme consisting of a dust collection port and a dust pump to control dust, the interception efficiency of the filter plate decreases significantly after long-term use, making it difficult to maintain effective filtration performance. Furthermore, since the filter plate is fixed by a rigid connection, this assembly method makes it difficult to disassemble and maintain the filter plate, and also affects the continuous operation efficiency of the dust collection system. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a downhole drilling rig with a multi-stage dust collection mechanism, so as to solve the problem that in the prior art, the filter plate is fixed by a rigid connection, which makes the disassembly and maintenance of the filter plate difficult and affects the continuous operation efficiency of the dust collection system.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a downhole drilling rig with a multi-stage dust collection mechanism, including a drilling mechanism, a support block, an air intake filter plate and a dust pump. A through groove is opened in the middle of the support block, a filter plate is inserted into the inner wall of the through groove, a plug-in block is installed at the bottom of the filter plate, slots are opened on both the front and rear sides of the inner wall of the through groove, and plug posts are inserted into both the front and rear sides of the lower part of the plug-in block. A dust collection groove is opened on the right side of the inside of the support block.
[0006] The plug-in block has movable grooves on both the front and rear sides inside. Movable plates are slidably connected to the inner walls of the movable grooves. Connecting rods are installed on the adjacent sides of the movable plates on both the front and rear sides. Elastic elements are sleeved on the outer sides of the connecting rods. Two sliding grooves are opened at the lower part of the plug-in block. A lever plate is slidably connected to the inner walls of the sliding grooves.
[0007] The connecting rods on both the front and rear sides pass through the sliding groove at their adjacent ends and are installed between them and the lever plate. One end of the elastic element is installed between it and the moving plate, and the other end is installed between it and the inner wall of the moving groove. The moving plates on both the front and rear sides are installed between them and the insert post at their adjacent ends. The insert post on both the front and rear sides passes through the moving groove at its adjacent ends.
[0008] The plug-in block has slots on both the front and rear sides of its top, a threaded groove in the middle, rubber protrusions on both the front and rear sides of its bottom, and a threaded post in the middle of its bottom wall.
[0009] The lower part of the threaded column is threaded to the inner wall of the threaded groove.
[0010] The rubber protrusion is engaged with the inner wall of the slot and is subjected to compression deformation.
[0011] The insertion blocks are inserted through one end of each of the front and rear insertion posts and are inserted into the inner wall of the slot. The insertion blocks are inserted into the lower side of the inner wall of the through slot, and the bottom of the insertion blocks is inserted through the support block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In the above solution, by driving the two side plugs to move towards each other so that their ends disengage from the slot, the locking state of the plug block and the through slot can be released. At this time, the operator can pull down the plug block and simultaneously drive the filter plate down, so as to quickly remove and clean the filter plate, thereby improving the convenience of maintenance operations. This not only reduces equipment downtime, but also restores the filtration performance of the dust collection mechanism in a timely manner, ensuring the continuous and efficient operation of dust removal.

Detailed Implementation
[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0026] Example 1: Please refer to Figures 1 to 9 This utility model provides a technical solution: an underground rock drilling rig equipped with a multi-stage dust collection mechanism, including a rock drilling mechanism 1, a support block 2, an air intake filter plate 3, and a dust pump 4. The support block 2 and the rock drilling mechanism body 1 are detachably installed for later removal. The rock drilling mechanism 1 is part of the underground rock drilling rig, and the main improvement is made to the rock drilling mechanism 1. Other parts are not shown in detail. A through groove 5 is opened in the middle of the support block 2. The through groove 5 and the dust collection groove 6 are designed to be connected to each other so that fine impurities can be collected after filtration by the filter plate 7. The inner wall of the through groove 5 is connected to a... The filter plate 7 has a plug-in block 8 installed at its bottom. The inner wall of the through groove 5 has slots 9 on both the front and back sides. The plug-in block 8 has a plug post 14 inserted on both the front and back sides at its lower part. The support block 2 has a dust collection groove 6 on its inner right side. The opposite ends of the plug posts 14 on the front and back sides pass through the plug-in block 8 and are inserted into the inner wall of the slot 9. The plug-in block 8 is locked to the lower inner wall of the through groove 5 by the cooperation between the plug post 14 and the slot 9, so as to facilitate subsequent cleaning. The plug-in block 8 is inserted into the lower inner wall of the through groove 5, and the bottom of the plug-in block 8 passes through the support block 2, so as to facilitate pulling the plug-in block 8 out downwards.
[0027] First, disengage one end of the insertion post 14 from the slot 9, then pull out the insertion block 8 downwards, and disengage the filter plate 7 from the inner wall of the through groove 5. Then, the cleaning operation can be performed. After completion, reset the filter plate 7 and the insertion block 8 and insert them back into the inner wall of the through groove 5, and keep one end of the insertion post 14 in the insertion state with the slot 9 for subsequent disassembly and use, thereby improving the performance of the dust collection mechanism.
[0028] Example 2: Based on Example 1, in order to ensure that the push pin 14 and the slot 9 are always in an inserted state, the insertion block 8 has movable grooves 20 on both the front and rear sides. Movable plates 15 are slidably connected to the inner walls of the movable grooves 20. Connecting rods 17 are installed on the adjacent sides of the movable plates 15 on both the front and rear sides. Elastic elements 16 are sleeved on the outer sides of the connecting rods 17. Two sliding grooves 18 are opened at the lower part of the insertion block 8. A lever plate 19 is slidably connected to the inner walls of the sliding grooves 18. The adjacent ends of the connecting rods 17 on both the front and rear sides are... The slide 18 is connected to the lever plate 19. One end of the elastic element 16 is connected to the movable plate 15, and the other end is connected to the inner wall of the movable groove 20. The elastic force of the elastic element 16 pushes the movable plate 15 to slide backward, and drives one end of the insertion post 14 to always be connected to the slot 9. The opposite sides of the front and rear movable plates 15 are connected to the insertion post 14. The near ends of the front and rear insertion posts 14 are connected to the movable groove 20, so that the movable plate 15 can easily drive the insertion post 14 to move.
[0029] First, pull the front and rear levers 19 to slide them towards each other along the inner wall of the slide groove 18, and pull the connecting rod 17 to drive the moving plate 15 to slide along the inner wall of the moving groove 20, thereby causing one end of the insertion post 14 to disengage from the slot 9. At the same time, squeeze the elastic element 16 to compress it on the inner wall of the moving groove 20. At this time, the insertion block 8 can be pulled out downwards, and the filter plate 7 can be disengaged from the inner wall of the through groove 5. Then, the cleaning operation can be performed. After that, reset the filter plate 7 and the insertion block 8 and insert them into the inner wall of the through groove 5, and release the front and rear levers 19. Then, use the elastic force of the elastic element 16 to push the moving plate 15 to slide back to reset, and cause one end of the insertion post 14 to continue to be inserted into the slot 9 for subsequent disassembly and use.
[0030] Example 3: Based on Example 2, in order to achieve modular assembly and reduce replacement costs by replacing the filter plate 7 individually, the top front and rear sides of the plug-in block 8 are provided with slots 12, the middle of the plug-in block 8 is provided with a threaded groove 13, the bottom front and rear sides of the filter plate 7 are provided with rubber protrusions 10, and the bottom wall of the filter plate 7 is provided with a threaded post 11. The lower part of the threaded post 11 is threaded to the inner wall of the threaded groove 13, thereby using the threaded post 11 to install the filter plate 7 and the plug-in block 8. The rubber protrusions 10 are engaged with the inner wall of the slots 12 and are squeezed and deformed, thereby increasing the friction between the filter plate 7 and the plug-in block 8 to improve the stability of the assembly between the two.
[0031] First, pull it downwards to disengage it from the through groove 5. Then, rotate the filter plate 7 to drive the threaded connection between the threaded post 11 and the inner wall of the threaded groove 13 to gradually disengage. At this time, the rubber protrusion 10 will simultaneously disengage from the slot 12. Then, the filter plate 7 can be replaced. After that, reset the replaced filter plate 7 and use the threaded connection between the threaded post 11 and the threaded groove 13 to fit downwards. At this time, the rubber protrusion 10 will gradually fit against the top of the plug block 8 and press the plug block 8 as the filter plate 7 is installed. When the filter plate 7 is fully assembled, the plug block 8 is inserted into the inner wall of the slot 12 and is in a state of compression deformation, thereby increasing the friction between the filter plate 7 and the plug block 8 and increasing the stability of the installation between the two.
[0032] The working process of this utility model is as follows:
[0033] In use, first pull the front and rear levers 19 to slide towards each other along the inner wall of the slide groove 18, and pull the connecting rod 17 to drive the moving plate 15 to slide along the inner wall of the moving groove 20, thereby causing one end of the insertion post 14 to disengage from the slot 9. At the same time, the elastic element 16 is squeezed, so that it is compressed in the inner wall of the moving groove 20. At this time, the insertion block 8 can be pulled out downwards, and the filter plate 7 is disengaged from the inner wall of the through groove 5. Then the cleaning operation can be performed. After completion, the filter plate 7 and the insertion block 8 are reset and inserted into the inner wall of the through groove 5, and the front and rear levers 19 are released. The elastic force of the elastic element 16 is used to push the moving plate 15 to slide back to reset, and one end of the insertion post 14 continues to be inserted into the slot 9 for subsequent disassembly and use, thereby improving the use effect of the dust collection mechanism.
[0034] When the filter plate 7 needs to be replaced, first pull it downwards to disengage it from the through groove 5. Then rotate the filter plate 7 to drive the threaded connection between the threaded post 11 and the inner wall of the threaded groove 13 to gradually disengage. At this time, the rubber protrusion 10 will simultaneously disengage from the slot 12. Then the filter plate 7 can be replaced. After that, reset the replaced filter plate 7 and use the screw connection between the threaded post 11 and the threaded groove 13 to fit downwards. At this time, the rubber protrusion 10 will gradually fit against the top of the plug block 8 and press the plug block 8 as the filter plate 7 is installed. When the filter plate 7 is fully assembled, the plug block 8 is inserted into the inner wall of the slot 12 and is in a state of compression deformation, thereby increasing the friction between the filter plate 7 and the plug block 8 and increasing the stability of the installation between the two.
