Description

Technical Field

[0001] This utility model relates to the field of rock drilling rig technology, specifically a collection device for rock drilling rigs. Background Technology

[0002] During rock drilling operations, the drill bit breaks rocks, generating a large amount of dust. If the dust is not collected in time, it will spread in the working environment, causing pollution. Therefore, a collection device is needed.

[0003] A Chinese patent with authorization announcement number CN215889950U discloses a collection device for a rock drilling rig, including a box body with an inner cavity. A partition plate is fixedly connected to the box body and is fixedly installed inside the inner cavity, dividing the inner cavity into a first collection cavity and a second collection cavity. A rock powder inlet is provided on the side wall of the box body, which is connected to the first collection cavity. A rock cuttings inlet is also provided on the box body, which is connected to the second collection cavity. This allows the rock powder and rock cuttings generated during the operation of the rock drilling rig to be placed in the inner cavity of the box body, thereby facilitating the placement of rock cuttings and rock powder generated during the rock drilling process. This reduces the accumulation of rock cuttings and rock powder on the blast hole, making it easier for subsequent workers to load explosives.

[0004] However, the above-mentioned device still has some problems. As the dust collection operation proceeds, dust will continuously adhere to the filter plate, clogging the pores of the filter plate, which will increase the ventilation resistance of the filter plate, reduce the working efficiency of the negative pressure motor, and reduce the dust collection capacity, making it impossible to effectively suck rock dust and rock chips into the collection box. Therefore, in order to solve the above problems, a collection device for rock drilling rigs is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a collection device for rock drilling rigs.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A collection device for rock drilling rigs, comprising a vehicle body, a collection box mounted on the top side of the vehicle body, a door panel mounted on one side of the collection box via a hinge, a conveying pipe connected to the top side of the collection box, the conveying pipe being "Y-shaped," and dust suction hoods installed at both ends of the conveying pipe; a negative pressure motor installed inside the bottom side of the collection box, three fan blades installed at the output end of the negative pressure motor; an exhaust pipe connected to one side of the bottom of the collection box; and a [missing information - likely a device or component] installed between the two sides of the middle of the collection box. Equipped with an arc-shaped filter plate, the filter plate has several teeth installed on its outer edge. An mounting plate is installed on the top side of one end of the collection box. An arc-shaped groove is opened inside the mounting plate, and a sliding block is slidably installed inside the arc-shaped groove. The sliding block is "I"-shaped. A dual-axis motor is installed on one side of the sliding block. Gears and cleaning brushes are respectively installed on the output end of the dual-axis motor. The gears and teeth mesh with each other, and the cleaning brush contacts the top side of the filter plate, realizing the centralized collection of dust and effective treatment of dust on the filter plate, ensuring the filtration effect.

[0007] Preferably, a mounting frame is installed on the top side of the vehicle body, a guide rod is installed between the two sides of the mounting frame, a servo motor is installed on the top side of the mounting frame, a threaded rod is installed at the output end of the servo motor, a sliding groove is opened inside one side of the mounting frame, a moving block is slidably installed inside the sliding groove, a screw hole and a positioning hole are opened inside the moving block, the guide rod is set through the positioning hole, and the threaded rod is rotatably installed inside the bottom side of the mounting frame through the screw hole, which can be flexibly adjusted according to the rock surface of different heights to improve work efficiency.

[0008] Preferably, a cylinder is installed on one side of the movable block, a drilling motor is installed on the working end of the cylinder, a rotating shaft is installed on the output end of the drilling motor, and a drill bit is assembled on one end of the rotating shaft to realize rock drilling operation.

[0009] Preferably, a fixing plate is installed on the outside of the drilling motor, and three T-shaped rods are equidistantly slidably installed inside the fixing plate. One end of each T-shaped rod is fixedly connected to a protective cover. Three compression springs are fixedly connected between the protective cover and the fixing plate. The compression springs are respectively sleeved on the outside of the T-shaped rods to prevent dust from overflowing and rocks from splashing.

[0010] Preferably, the protective cover is slidably installed on the outside of the rotating shaft, and the dust suction covers are respectively installed inside the protective cover to ensure the dust suction effect during the rock drilling process.

[0011] Preferably, a controller is installed on the top side of the vehicle body. The controller is used to operate and control the electrical components inside the device, thereby realizing centralized control of the electrical components inside the device.

[0012] The advantages of this utility model are:

[0013] 1. This utility model starts a dual-axis motor, one of which drives the gear to rotate. The dual-axis motor slides in the arc-shaped groove through a sliding block, thereby driving the cleaning brush to move along the top side of the filter plate. The other output of the dual-axis motor drives the cleaning brush to rotate. Through the rotation and movement of the cleaning brush, the dust adsorbed on the filter plate is cleaned to both sides, so that the filter plate can maintain good filtration performance and ensure the normal operation of the entire collection device.

Detailed Implementation

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-5 As shown, a collection device for rock drilling rigs includes a vehicle body 1. A collection box 2 is mounted on the top side of the vehicle body 1. A door panel is hinged to one side of the collection box 2. A conveying pipe 3 is connected to the top side of the collection box 2. The conveying pipe 3 is Y-shaped and has dust suction hoods 4 installed at both ends. A negative pressure motor 5 is installed inside the bottom side of the collection box 2. Three fan blades 6 are installed at the output end of the negative pressure motor 5. An exhaust pipe 7 is connected to one side of the bottom of the collection box 2. An arc-shaped [feature / structure] is installed between the two sides of the middle of the collection box 2. The filter plate 8 has several teeth 9 installed on one outer edge. The collection box 2 has an installation plate 10 installed on one top side. The installation plate 10 has an arc-shaped groove 11 inside. A sliding block 12 is slidably installed inside the arc-shaped groove 11. The sliding block 12 is in the shape of an "I". A dual-axis motor 13 is installed on one side of the sliding block 12. A gear 14 and a cleaning brush 15 are respectively installed on the output end of the dual-axis motor 13. The gear 14 meshes with the teeth 9. The cleaning brush 15 contacts the top side of the filter plate 8.

[0024] The protective cover 28 is slidably mounted on the outside of the rotating shaft 24, and the dust suction covers 4 are respectively installed inside the protective cover 28;

[0025] A controller 30 is installed on the top side of the vehicle body 1. The controller 30 is used to control the operation of the electrical components inside the device. During operation, as the dust collection work is carried out, dust will be continuously adsorbed on the filter plate 8, clogging the pores of the filter plate 8, which will increase the ventilation resistance of the filter plate 8, reduce the working efficiency of the negative pressure motor 5, and reduce the dust collection capacity. It will be unable to effectively suck the rock dust and rock chips into the collection box 2. During the rock drilling process, the controller 30 starts the negative pressure motor 5, which drives the fan blade 6 to rotate at high speed, generating negative pressure in the collection box 2. The dust and small rock chips generated in the protective cover 28 are sucked into the dust collection cover 4, and then enter the collection box 2 through the conveying pipe 3. The dust-laden airflow entering the collection box 2 passes through the arc-shaped filter plate 8, and the dust is blocked and adsorbed on its surface by the filter plate 8. The filtered air is discharged from the collection box 2 through the exhaust pipe 7, realizing the centralized collection and preliminary filtration of dust.

[0026] To ensure the filtration effect of the filter plate 8 and prevent dust from clogging it, the controller 30 periodically starts the dual-axis motor 13. One output of the motor drives the gear 14 to rotate. Since the gear 14 meshes with the teeth 9, the dual-axis motor 13 slides in the arc groove 11 through the sliding block 12, thereby driving the cleaning brush 15 to move along the top side of the filter plate 8. The other output of the dual-axis motor 13 drives the cleaning brush 15 to rotate. Through the rotation and movement of the cleaning brush 15, the dust adsorbed on the filter plate 8 is cleaned to both sides, so that the filter plate 8 can maintain good filtration performance and ensure the normal operation of the entire collection device.

[0027] Please see Figure 1 , 2 As shown in Figures 3 and 5, a mounting frame 16 is installed on the top side of the vehicle body 1, a guide rod 17 is installed between the two sides of the mounting frame 16, a servo motor 18 is installed on the top side of the mounting frame 16, a threaded rod 19 is installed at the output end of the servo motor 18, a sliding groove 21 is opened inside one side of the mounting frame 16, a moving block 20 is slidably installed inside the sliding groove 21, a screw hole and a positioning hole are opened inside the moving block 20, the guide rod 17 is set through the positioning hole, and the threaded rod 19 is rotatably installed inside the bottom side of the mounting frame 16 through the screw hole;

[0028] A cylinder 22 is installed on one side of the moving block 20. A drilling motor 23 is installed on the working end of the cylinder 22. A rotating shaft 24 is installed on the output end of the drilling motor 23. A drill bit 25 is assembled on one end of the rotating shaft 24.

[0029] A fixing plate 26 is installed on the outside of the drilling motor 23. Three T-shaped rods 27 are equidistantly slidably installed inside the fixing plate 26. One end of each T-shaped rod 27 is fixedly connected to a protective cover 28. Three compression springs 29 are fixedly connected between the protective cover 28 and the fixing plate 26. The compression springs 29 are respectively sleeved on the outside of the T-shaped rods 27. During operation, in the early exploration stage of the construction site, rock drilling is required to obtain rock samples for some rock walls. By analyzing these samples, the physical and mechanical properties of the rock wall, such as type, strength, and weathering degree, can be understood. First, the servo motor 18 is started by the controller 30. The servo motor 18 drives the threaded rod 19 to rotate, so that the moving block 20 moves up and down along the guide rod 17 in the slide groove 21. This realizes the precise adjustment of the height position of the drilling motor 23 according to the rock surface of different heights, so that the drill bit 25 can be aligned with the rock working surface, thereby improving the working efficiency.

[0030] Once the moving block 20 is adjusted to the appropriate height, the controller 30 activates the cylinder 22. The actuating end of the cylinder 22 pushes the drilling motor 23 forward, causing the drill bit 25 to contact the rock surface. Then, the drilling motor 23 starts, and its output end drives the rotating shaft 24 to rotate, thereby causing the drill bit 25 to rotate at high speed to perform drilling operations on the rock. During the drilling process, a large amount of dust and rock chips will be generated. At this time, the compression spring 29 provides a certain preload, so that the protective cover 28 can fit tightly against the rock working surface to prevent dust from overflowing and rock from splashing. On the other hand, when the drill bit 25 encounters different rock hardness or changes in drilling depth, the T-shaped rod 27 can slide within the fixed plate 26, and the compression spring 29 will extend and retract accordingly, so that the protective cover 28 can adaptively adjust its position and always maintain a good protective effect.

[0031] Working principle: First, the servo motor 18 is started by the controller 30. The servo motor 18 drives the threaded rod 19 to rotate, so that the moving block 20 moves up and down along the guide rod 17 in the slide groove 21. This realizes the precise adjustment of the height position of the drilling motor 23 according to the rock surface of different heights, so that the drill bit 25 can be aligned with the rock working surface and improve the working efficiency.

[0032] Once the moving block 20 is adjusted to the appropriate height, the controller 30 activates the cylinder 22. The actuating end of the cylinder 22 pushes the drilling motor 23 forward, causing the drill bit 25 to contact the rock surface. Then, the drilling motor 23 starts, and its output end drives the rotating shaft 24 to rotate, thereby causing the drill bit 25 to rotate at high speed to perform drilling operations on the rock. During the drilling process, a large amount of dust and rock chips will be generated. At this time, the compression spring 29 provides a certain preload, allowing the protective cover 28 to fit tightly against the rock working surface, preventing dust from overflowing and rock from splashing. On the other hand, when the drill bit 25 encounters different rock hardness or changes in drilling depth, the T-shaped rod 27 can slide within the fixed plate 26, and the compression spring 29 will extend and retract accordingly, allowing the protective cover 28 to adaptively adjust its position and always maintain a good protective effect.

[0033] During rock drilling, the controller 30 starts the negative pressure motor 5, which drives the fan blade 6 to rotate at high speed, generating negative pressure in the collection box 2. The dust and small rock chips generated in the protective cover 28 are sucked into the dust suction cover 4, and then enter the collection box 2 through the conveying pipe 3. The dust-laden airflow entering the collection box 2 passes through the arc-shaped filter plate 8, and the dust is blocked and adsorbed on its surface by the filter plate 8. The filtered air is discharged from the collection box 2 through the exhaust pipe 7, realizing the centralized collection and preliminary filtration of dust.

[0034] To ensure the filtration effect of the filter plate 8 and prevent dust from clogging it, the controller 30 periodically starts the dual-axis motor 13. One output of the motor drives the gear 14 to rotate. Since the gear 14 meshes with the teeth 9, the dual-axis motor 13 slides in the arc groove 11 through the sliding block 12, thereby driving the cleaning brush 15 to move along the top side of the filter plate 8. The other output of the dual-axis motor 13 drives the cleaning brush 15 to rotate. Through the rotation and movement of the cleaning brush 15, the dust adsorbed on the filter plate 8 is cleaned to both sides, so that the filter plate 8 can maintain good filtration performance and ensure the normal operation of the entire collection device.
