Description

Technical Field

[0001] The utility model relates to the field of rotary drills, in particular to a dust prevention and removal system for inclined hole drilling of rotary drills. Background Art

[0002] Rotary drills usually use high-volume, low-pressure air compressors for slag removal. A large amount of floating dust will be generated during the operation, which seriously affects the environment and human health. Therefore, wet or dry dust removal is used. In order to ensure the dust removal effect, a dust cover needs to be installed at the orifice to prevent the floating dust from spreading to a large space. When wet dust removal is used, water will be injected into the air intake pipe to form a spray, which has a better dust removal effect and does not require high sealing of the dust cover. However, the disadvantages of wet dust removal are: in some water-scarce areas, it is difficult to obtain water resources, the cost of use is high, and it takes a lot of energy to solve the problem of freezing in winter. To solve these problems, rotary drills use dry dust collectors. Dry dust removal uses suction and filtration to deal with floating dust. This method requires the dust cover to have good sealing properties, otherwise the dust removal effect will be poor. However, in order to adapt to various working conditions of rotary drills, the dust cover must be able to be opened and closed, and at the same time, it is required that the sealing effect can be ensured without human intervention, so that the operator can operate the equipment without leaving the cab or in the remote control room. Therefore, there is an urgent need for a dust prevention and dust removal system with a high degree of automation and good sealing properties to ensure dust removal effects. Utility Model Content

[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Reference Figures 1 to 4 As shown, a dust prevention and removal system for inclined hole drilling by a rotary drill according to an embodiment of the utility model comprises: a drilling platform 100, a dust cover assembly, and a dust removal mechanism 300.

[0035] The drilling rig platform 100 is provided with a platform bottom plate 110, and a drill rack 120 is rotatably provided on the upper side of the platform bottom plate 110 of the drilling rig platform 100. The drill rack 120 is used to install a drill rod (not shown in the figure). A vertically through-going installation opening 111 is provided on the platform bottom plate 110, and a dust isolation structure is embedded in the installation opening 111. The dust isolation structure is configured to allow the drill rod to pass through and abut against the outer wall of the drill rod.

[0036] The dust cover assembly includes four dust cover plates 200, the top end of the dust cover plates 200 is rotatably arranged on the lower side of the platform bottom plate 110, and the four dust cover plates 200 are distributed around the peripheral side of the mounting opening 111. The dust cover plates 200 are connected to a driving member 210 for driving the dust cover plates 200 to rotate. The dust cover plates 200 have a first state and a second state during rotation, and the driving member 210 drives the dust cover plates 200 to switch between the first state and the second state. When the four dust cover plates 200 are in the first state, the adjacent side edges of any two adjacent dust cover plates 200 abut against each other, and the four dust cover plates 200 are in the first state. A vertically distributed dustproof channel is formed between the dust plates 200, and the dustproof channel is located directly below the installation port 111, that is, the four dustproof plates 200 can be spliced ​​at the lower side of the installation port 111 to form a rectangular cover structure when they are in the first state; when the four dustproof plates 200 are in the second state, the four dustproof plates 200 are unfolded from each other, at this time, the height difference from the top to the bottom of the dustproof plate 200 is smaller than the height difference from the top to the bottom of the dustproof plate 200 in the first state, that is, when the dustproof plate 200 is in the second state, the dustproof plate 200 is farther from the ground. It can be understood that when drilling an oblique hole, the drill rod passes through the dustproof structure in the installation port 111 and then passes between the four dustproof plates 200 to drill into the ground.

[0037] The dust removal mechanism 300 includes a dry dust collector 310 and a dust suction duct 320. The dust suction duct 320 is used to be connected to the dustproof channel. The air in the dustproof channel is extracted through the dry dust collector 310 and the dust suction duct 320 to form a negative pressure in the dustproof channel. The dust raised when the drill rod is drilling will enter the dry dust collector 310 through the dust suction duct 320 for filtering and dust removal.

[0038] The dust prevention and removal system for inclined hole drilling of a rotary drill according to the embodiment of the utility model, when the inclined hole drilling is carried out (i.e., the use condition), the drill rod passes through the dust isolation structure in the installation port 111 and then passes through between the four dust prevention plates 200 and drills into the ground, and the driving member 210 drives the dust prevention plates 200 to rotate to the first state, so that the four dust prevention plates 200 are all rotated to the first state, abut against each other to splice into a rectangular cover structure, and form a vertically distributed dust prevention channel inside, and then the dry dust collector 310 is started, and the air in the dust prevention channel is extracted through the dust suction pipe 320 to form a negative pressure, thereby removing the dust raised by the drill rod during drilling through the suction pipe 320. The dust duct 320 sucks the dry dust collector 310 for filtering and dust removal, and because a dust isolation structure is provided at the installation port 111, dust can be prevented from entering the upper side of the platform bottom plate 110 along the outer wall of the drill pipe, and as much dust as possible can be blocked in the dustproof channel, resulting in a good dust removal effect; and when the drilling is completed and the drilling rig platform 100 needs to be moved (i.e., walking condition), the driving component 210 can drive the dustproof plate 200 to rotate to the second state, thereby increasing the height of the dustproof plate 200 from the ground and preventing protruding ore rocks or slag from scratching the dustproof plate 200. The state switching of the dustproof plate 200 is controlled by the driving component 210, without manual operation, with a high degree of automation and high safety.

[0039] Reference Figure 1 and Figure 3 As shown, it can be understood that an oblique hole dust cover 130 is provided at one end of the drill rig 120 facing the platform bottom plate 110, and the oblique hole dust cover 130 is arranged around the peripheral side of the drill rod, and the oblique hole dust cover 130 is arranged at one end away from the drill rig 120. The oblique hole dust cover 130 is configured as follows: when the drill rig 120 is rotated to a set angle, the end of the oblique hole dust cover 130 away from the drill rig 120 abuts against the upper surface of the platform bottom plate 110, and the mounting port 111 is located on the inner side of the oblique hole dust cover 130, so that the mounting port 111 and the drill rod are covered by the oblique hole dust cover 130, even if some dust passes through the dust isolation structure and enters the upper side of the platform bottom plate 110, the oblique hole dust cover 130 can prevent the dust from continuing to escape to the surrounding environment, thereby improving the dust prevention effect. It is conceivable that a drill tool dust cover (not shown) can also be provided on the inner side of the inclined hole dust cover 130 of the drill rig 120. The drill tool dust cover is provided on the peripheral side of the drill rod and abuts against the outer wall of the drill rod. The part of the drill tool dust cover that abuts against the drill rod can be made of rubber material. The drill tool dust cover, the inclined hole dust cover 130 and the dust isolation structure jointly prevent dust from entering along the outer wall of the drill rod to the top of the platform bottom plate 110 and escaping to the surrounding environment.

[0040] It is understandable that the material of the oblique hole dust cover 130 is rubber. Since rubber is elastic, when the drill frame 120 is rotated to different angles for drilling oblique holes at different angles, it can be ensured that the end of the oblique hole dust cover 130 away from the drill frame 120 abuts against the platform bottom plate 110 to ensure good sealing. In addition, it is understandable that in order to adapt to oblique hole drilling at different angles, the dust isolation structure is configured to allow the drill rod to pass through and abut against the outer wall of the drill rod when the drill frame 120 is rotated to multiple angles. Specifically, Figure 2 As shown, the dust isolation structure includes a dust isolation plate 140 made of rubber, and a plurality of vertical through grooves 141 are provided on the dust isolation plate 140. The through grooves 141 are used for the drill rod to pass through. Since rubber has elasticity, it can ensure that the drill rod at different drilling angles can pass through the dust isolation plate 140, and can ensure a good sealing effect.

[0041] Reference Figure 1 As shown, it can be understood that the end of the inclined hole dust cover 130 close to the drill frame 120 is fixedly connected to the metal frame 131, and the metal frame 131 is connected to the drill frame 120 by bolts. In this way, the inclined hole dust cover 130 can be easily installed on the drill frame 120, and it is also convenient to replace the inclined hole dust cover 130 when it is damaged.

[0042] Reference Figure 1 and Figure 2 As shown, it can be understood that the drilling rig platform 100 is formed with a rectangular groove 101 with an open bottom on the lower side of the platform bottom plate 110, the rectangular groove 101 is located at the lower side of the mounting opening 111, and the projection of the mounting opening 111 on the horizontal plane falls within the projection range of the rectangular groove 101 on the horizontal plane, the dust suction duct 320 is installed on the drilling rig platform 100 and one end extends into the rectangular groove 101, and the four dustproof plates 200 are respectively rotatably arranged on the four sides of the bottom end of the rectangular groove 101, so that when the dustproof plates 200 rotate, interference with the dust suction duct 320 can be avoided.

[0043] Reference Figure 2 and Figure 3 As shown, it can be understood that the dust suction duct 320 includes a dust suction hose 321 and a dust suction hard pipe 322 which are interconnected. The end of the dust suction hose 321 away from the dust suction hard pipe 322 is connected to the dry dust collector 310. The dust suction hard pipe 322 extends into the rectangular groove 101 and has a dust suction port 323 tilted downward. Obviously, the dust suction hard pipe 322 is used to suck away the dust in the dustproof channel. By providing the dust suction hose 321, the dry dust collector 310 can be easily arranged and the pipe twisting damage can be avoided. The dust suction hard pipe 322 is provided and extended into the rectangular groove 101 for dust suction. Since it is a hard pipe, it will not move at will, so the dust suction effect can be guaranteed. In addition, a dust suction port 323 tilted downward is formed on the dust suction hard pipe 322, which can better suck away the dust.

[0044] Reference Figure 3 As shown, it can be understood that the driving member 210 is arranged on the outer side of the dustproof plate 200, so as to prevent dust from corroding the driving member 210 and causing damage to the driving member 210.

[0045] Reference Figure 3 As shown, it can be understood that the driving member 210 includes a hydraulic cylinder, a fixed end of the hydraulic cylinder is hinged to the drilling rig platform 100, and a telescopic end of the hydraulic cylinder is hinged to the dustproof plate 200. The rotation of the dustproof plate 200 is controlled by the telescopic movement of the hydraulic cylinder, which is stable and reliable.

[0046] Reference Figure 3 and Figure 4 As shown, it can be understood that the dust prevention and dust removal system for inclined hole drilling of a rotary drill according to an embodiment of the utility model also includes a monitoring device, which includes a camera 400. The camera 400 is installed on the drilling rig platform 100 and is set corresponding to one of the dustproof plates 200. The camera 400 is used to shoot the picture between the other three dustproof plates 200 when the corresponding dustproof plate 200 rotates to the second state. In this way, when drilling an inclined hole, the dustproof plate 200 corresponding to the camera 400 can be rotated to the second state, and then the slag removal and dust removal in the dust cover assembly can be viewed through the camera 400, so that the operator can grasp the real-time working status of the equipment. In some specific embodiments, for the convenience of control, the hydraulic cylinder connected to the dustproof plate 200 corresponding to the camera 400 is controlled separately by one hydraulic valve, and the hydraulic cylinders connected to the other three dustproof plates 200 are controlled together by one hydraulic valve.

[0047] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
