Description

Technical Field

[0001] The invention relates to the field of blasting drilling, and in particular to a drilling and blasting operation system and an information management method thereof. Background Art

[0002] The drilling and blasting system is an engineering system that integrates drilling, charging and blasting, and is mainly used in mining, tunnel construction, building demolition and other fields. Its core is to drill holes in the rock mass through professional drilling equipment, load explosives and blast, and use the explosive energy to break the rock to achieve the predetermined engineering goals.

[0003] In the existing blasting, it is necessary to first drill a hole in the medium and then fill the drill with explosives. The straight hole of the traditional blasting drill hole is easy to drill, but the impact force generated by the ignition of the explosive mainly rushes out along the direction of the hole mouth, and the requirements for the hole mouth sealing are high. If the hole mouth is not tightly sealed, the impact force of the blasting will be weakened. Therefore, a trumpet-shaped hole with a diameter that increases with depth is used so that the impact force generated by the blasting can be sufficiently released before impacting the medium on the hole wall; however, the trumpet-shaped hole is inconvenient to drill, and after drilling, the gravel particles remaining inside are difficult to remove due to the inward deviation of the trumpet-shaped hole. If the gravel remaining inside the borehole is not cleaned up, it will lead to insufficient contact between the explosive and the hole wall, affecting the effective transfer of the explosive energy, thereby reducing the blasting efficiency and failing to achieve the expected rock crushing effect. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a drilling and blasting operation system and an information management method thereof.

[0005] In a first aspect, the present invention provides a drilling and blasting system, comprising:

[0006] The measurement and hole layout design unit is used to collect the boundary and key point information of the blasting area through a high-precision GPS measurement terminal, and then upload the information to the server to design the hole layout according to the blasting area range and generate a hole layout design diagram, including the drilling number, location, depth and other information;

[0007] The drilling unit is used to drill trumpet-shaped holes at the locations where holes need to be drilled according to the drilling requirements, and to clean the gravel generated by the drilling in real time during the drilling process, so that the hole can be automatically cleaned after the drilling is completed, and the data is automatically uploaded to the server after the drilling is completed;

[0008] The charging unit is used to fill the explosives into the blasthole according to the design requirements, and after the charging is completed, it is blocked with gun mud or other materials to prevent gas leakage;

[0009] The detonating unit is used to detonate by means of electric detonation or detonating cord detonation, and monitor the detonation situation through a monitoring test.

[0010] Preferably, the drilling unit includes:

[0011] A bracket on which a housing is mounted;

[0012] A cylinder fixed to the bracket and pushing the housing to move through a telescopic rod;

[0013] A rotating cylinder rotatably mounted at the end of the housing;

[0014] A first motor fixed inside the housing and driving the rotating cylinder to rotate through an output shaft;

[0015] A plurality of second flipping ends flip - mounted in a circumferential array at the end of the rotating cylinder;

[0016] A plurality of first flipping ends are arranged in one - to - one correspondence with the second flipping ends, and one end of each of the first flipping ends is respectively rotatably mounted at one end of each of the second flipping ends away from the rotating cylinder;

[0017] A drill bit, and the other ends of all the first flipping ends are flip - connected to the drill bit;

[0018] A moving drive assembly installed between the drill bit and the rotating cylinder for driving the drill bit to linearly move relative to the rotating cylinder;

[0019] A cleaning assembly installed between the drill bit and the rotating cylinder for cleaning the generated crushed stones while the drill bit is drilling;

[0020] When drilling is required, the operator holds the bracket or fixes the bracket on the ground so that the drill bit is aligned with the position where drilling is to be carried out. Subsequently, the first motor is started. After the first motor is started, it drives the rotating cylinder connected thereto to rotate through the output shaft. After the rotating cylinder rotates, it drives the second flipping end connected thereto to revolve around the rotating cylinder. After the second flipping end revolves, it drives the first flipping end rotatably connected thereto to revolve around the rotating cylinder. After the first flipping end revolves, it drives the drill bit to rotate, so as to drill the position where drilling is required through the rotation of the drill bit and the first flipping end and the second flipping end. After the air cylinder is started, it can drive the housing connected thereto to move, thereby driving the drill bit to move and enabling drilling to a specified depth. After drilling to the specified depth, the mobile driving assembly is started. The mobile driving assembly drives the drill bit to move towards the direction of the rotating cylinder, shortening the position between the rotating cylinder and the drill bit, thereby driving the generation of flipping between the first flipping end and the second flipping end, so that the first flipping end and the second flipping end flip and unfold, forming a flared hole between the first flipping end and the second flipping end, thereby expanding the drilling radius inside the drilling through the unfolded first flipping end and second flipping end, which is beneficial to increasing the radius of the drilling inside with the increase of depth, enabling the impact force generated by blasting to be sufficiently released before impacting the medium on the hole wall, thereby being beneficial to improving the blasting effect;

[0021] While drilling, the cleaning assembly is started. The cleaning assembly can clean the crushed stones while drilling, which is beneficial to synchronously cleaning the crushed stones inside the drilling, beneficial to preventing the crushed stones from remaining inside the drilling, and thus beneficial to stabilizing the blasting efficiency and achieving the expected rock breaking effect;

[0022] The outer walls of the first flipping end, the second flipping end, and the drill bit are all provided with polishing particles, which is beneficial to improving the drilling efficiency.

[0023] Preferably, the mobile driving assembly includes:

[0024] A second motor, fixed inside the rotating cylinder through a first mounting shell;

[0025] A screw rod, rotatably installed at the end of the rotating cylinder. The output shaft of the second motor drives the screw rod to rotate through a rotating shaft;

[0026] A threaded sleeve, rotatably installed at the end of the drill bit, and the threaded sleeve is threadedly connected to the screw rod;

[0027] After the second motor is started, it drives the rotating shaft connected thereto to rotate through the output shaft. After the rotating shaft rotates, it drives the screw rod connected thereto to rotate. After the screw rod rotates, it drives the threaded sleeve threadedly connected thereto to move. The threaded sleeve drives the drill bit to move, thereby adjusting the distance between the drill bit and the rotating cylinder, adjusting the flipping angle between the first flipping end and the second flipping end, and thus adjusting the outward expansion distance inside the drilling, so as to be able to perform drilling operations with different internal diameters according to the drilling requirements.

[0028] Preferably, the cleaning component includes:

[0029] An air chamber, fixed to the outer wall of the rotating cylinder;

[0030] A negative pressure pump, fixed to the outer wall of the housing through a second mounting shell;

[0031] A negative pressure pipe, with both ends fixedly connected to the negative pressure pump and the air chamber respectively, and an electromagnetic valve is fixed inside the negative pressure pipe;

[0032] A filter frame, fixed to the inner wall of the air chamber, and the filter frame covers the end opening of the negative pressure pipe;

[0033] An inner cavity, opened inside the rotating cylinder;

[0034] A first through opening, penetratingly opened on the inner circumferential side wall of the air chamber;

[0035] Second openings, arranged in a circumferential array on the side wall of the rotating cylinder, and the second openings are in communication and fit with the first through opening;

[0036] A plurality of first insertion pipes, fixed to the end of the rotating cylinder in a circumferential array, and all communicate with the inner cavity;

[0037] A plurality of second insertion pipes, respectively sealed and slidably inserted into each of the first insertion pipes at one end, and the other ends all communicate with a recovery cavity opened inside the drill bit;

[0038] A plurality of first openings, arranged in a circumferential array on the side wall of the drill bit, and communicate with the recovery cavity;

[0039] After the negative pressure pump is started, it drives the air flow. Through the negative pressure pipe, a negative pressure is formed inside the air chamber connected to it. Thus, under the action of the negative pressure, the air flow is driven to flow along the trajectory of the first opening, the recovery cavity, the second insertion pipe, the first insertion pipe, the inner cavity, the second opening, the first through opening, and the air chamber, thereby driving the crushed stones to flow into the air chamber along with the air flow. The settings of the second opening and the first through opening enable the second opening to rotate when the rotating cylinder rotates, and after the second opening rotates, it remains in communication with the first through opening, thus remaining in communication with the air chamber. When the crushed stones enter the air chamber, they are retained inside the air chamber under the filtering action of the filter frame, while the air flow passes through the negative pressure pipe and is discharged, thereby realizing the recovery of the crushed stones;

[0040] There are two openings in the negative pressure pipe, which are respectively connected to both ends inside the air chamber. By setting solenoid valves, it is possible to switch the two openings of the negative pressure pipe when switching the solenoid valves, thereby switching the air flow position, which is beneficial to avoiding the situation where the crushed stones driven by the air flow accumulate at the same position and cause blockage inside the air chamber. This is beneficial to cleaning the crushed stones generated during drilling while drilling, which is beneficial to improving the drilling efficiency and is also beneficial to improving the effect of explosion operations inside the drill hole;

[0041] A first guiding block is provided at the end of the rotating cylinder to guide the air flow and crushed stones, which is beneficial to improving the fluidity of the crushed stone recovery and avoiding the situation where the crushed stone recovery is blocked and affects the recovery efficiency.

[0042] Preferably, the cleaning assembly further includes:

[0043] Multiple negative pressure ports are respectively formed through the side walls of each of the second insertion pipes, and the negative pressure ports are blocked by the first insertion pipe;

[0044] Multiple communication ports are respectively formed through the side walls of each of the first insertion pipes, and the communication ports are blocked by the second insertion pipe. When the second insertion pipe moves relative to the first insertion pipe, the negative pressure ports move past the communication ports to form a connection;

[0045] When adjusting the position of the drill bit, the movement of the drill bit drives the connected second insertion pipe to move. The second insertion pipe drives the negative pressure ports to move relative to the communication ports. When the negative pressure ports move to the position of the communication ports, a connection is formed between the negative pressure ports and the communication ports. At this time, the first flipping end and the second flipping end are in the flipped state, so that a gap is exposed between the first flipping end and the second flipping end, enabling the crushed stones to enter the interior through the gap exposed between the first flipping end and the second flipping end, and then enter the interior of the second insertion pipe along the position where the negative pressure ports and the communication ports are connected. This enables the crushed stones to be recovered under the action of the air flow, which is beneficial to increasing the recovery positions of the crushed stones and thus beneficial to improving the recovery efficiency of the crushed stones;

[0046] The long-distance setting of the communication ports enables the negative pressure ports and the communication ports to remain connected when the drill bit moves within a certain range, so that within a certain movement range, the recovery effect of the crushed stones can be maintained, which is beneficial to improving the recovery efficiency of the crushed stones.

[0047] Preferably, it further includes:

[0048] Multiple first springs are fixedly arranged on the outer wall of the threaded sleeve in a circumferential array;

[0049] Multiple support plates are respectively fixed to one end of each of the first springs facing away from the threaded sleeve;

[0050] A plurality of telescopic sleeves are respectively sleeved on the outer circles of the respective first springs, and both ends of the telescopic sleeves are fixedly connected to the support plate and the outer wall of the threaded sleeve respectively;

[0051] When the drill bit moves towards the rotating cylinder, the first spring can push the support plate to move under the action of its own elastic force. The movement of the support plate pushes the first flipping end and the second flipping end to flip. Thus, when the first flipping end and the second flipping end are initially flush, the support plate can push the first flipping end and the second flipping end to flip, which is beneficial to promoting the flipping of the first flipping end and the second flipping end and avoiding the situation that it is difficult to flip due to the abutment of the first flipping end and the second flipping end in the initial state.

[0052] Preferably, it further includes:

[0053] A moving connecting cylinder is fixedly arranged inside the inner cavity through a limiting track;

[0054] A cross bar is fixed inside one end of the moving connecting cylinder facing the second insertion pipe. When one of the second insertion pipes moves towards the moving connecting cylinder and inserts into the inside of the moving connecting cylinder, the cross bar is used to push the moving connecting cylinder to move;

[0055] A plurality of third openings are respectively formed in the side walls of the moving connecting cylinder;

[0056] An air flow frame is fixed inside the inner cavity;

[0057] A rotating connection mechanism is installed between the air flow frame and the output end of the negative pressure pump and is used to connect the air flow frame and the negative pressure pump while the rotating cylinder rotates;

[0058] An elastic connection mechanism is installed between the moving connecting cylinder and the air flow frame and is used to connect the air flow frame after the second insertion pipe pushes the moving connecting cylinder to move;

[0059] A guiding bin is fixed inside the recovery cavity. One end is in communication with the moving connecting cylinder, the first insertion pipe and the second insertion pipe, and the other end is in communication with one of the first openings;

[0060] The negative pressure pump conveys air flow to the air flow frame through a rotating connection mechanism. After the drill bit moves a certain distance, it drives the second insertion pipe to move a certain distance, so that the second insertion pipe moves through the first insertion pipe and then penetrates out, causing the second insertion pipe to push the cross bar, and then pushing the moving connection cylinder through the cross bar, so that the moving connection cylinder moves along the track of the limiting track, gradually pushing the moving connection cylinder towards the air flow frame, thus pushing the elastic connection mechanism, making the air flow frame communicate with the moving connection cylinder. At this time, the air flow inside the air flow frame is conveyed along the moving connection cylinder to the connected first insertion pipe and second insertion pipe, so that the air flow flows along the first insertion pipe and then passes through the guiding chamber and is discharged from the first opening communicated with it, so that the air flow flows into the inside of the drill hole. The impact force of the air flow drives the gravel inside the drill hole to move, which is conducive to driving the gravel into the range of the negative pressure air flow by the acting force of the impact air flow, which is conducive to driving the recovery of the gravel, so as to improve the recovery effect of the gravel, and thus is conducive to improving the subsequent explosion effect inside the drill hole.

[0061] Preferably, the rotating connection mechanism includes:

[0062] An annular chamber, fixed inside the inner cavity, and a channel is provided at the center of the annular chamber;

[0063] A plurality of second through holes, arranged in a circumferential array on the side wall of the annular chamber and penetrating the side wall of the rotating cylinder;

[0064] A connection chamber, fixed inside the air chamber, and the opening penetrates the air chamber and is aligned and communicated with the second through hole;

[0065] An air inlet pipe, fixedly connected between the output end of the negative pressure pump and the connection chamber;

[0066] A communication cylinder, fixedly connected between the annular chamber and the air flow frame;

[0067] The negative pressure pump is connected to the connection chamber through the air inlet pipe. The connection chamber is connected to the annular chamber through the second through hole. The channel in the inner circle of the annular chamber can allow the air flow to drive the gravel through. The annular chamber is connected to the communication cylinder, and the communication cylinder is connected to the air flow frame, so as to drive the air flow to enter the air flow frame from the output end of the negative pressure pump. When the rotating cylinder rotates, it drives the annular chamber and the second through hole to rotate, so as to maintain the connection with the connection chamber through the second through holes arranged in a circumferential array.

[0068] Preferably, the elastic connection mechanism includes:

[0069] A shielding plate, clamped inside the ventilation opening provided on the air flow frame;

[0070] A third spring, fixed between the shielding plate and the inner wall of the air flow frame, and pushes the shielding plate to block the ventilation opening through the elastic force;

[0071] A second spring is fixed between the shielding plate and the movable connecting cylinder;

[0072] A second guiding block is fixed to the end of the movable connecting cylinder;

[0073] The second insertion pipe pushes the cross bar to drive the movable connecting cylinder to move, so that the movable connecting cylinder squeezes the second spring, and the second spring pushes the shielding plate, so that the shielding plate moves out of the ventilation port. The shielding plate squeezes the third spring and enters the inside of the air flow frame until the movable connecting cylinder gradually inserts into the inside of the air flow frame. The movable connecting cylinder communicates with the inside of the air flow frame through the third opening, so that the air flow can pass through the movable connecting cylinder and enter the inside of the first insertion pipe, so as to drive the air flow to enter the inside of the first insertion pipe after the drill bit moves to form an air flow impact;

[0074] When the movable connecting cylinder is not communicated with the air flow frame, the second guiding block can guide the flow of the crushed stones driven by the negative pressure air flow.

[0075] In a second aspect, an information management method for a drilling and blasting operation system is provided. A control unit is installed on the support, and the control unit includes a user end. The management method includes the following steps:

[0076] Step 1: The control unit obtains drilling information from the user end, and the drilling information includes drilling depth information and bell mouth radius information;

[0077] Step 2: The control unit controls the first motor to start according to the start information obtained from the user end;

[0078] Step 3: The control unit controls the cylinder to push the housing to move a distance corresponding to the drilling depth according to the drilling depth information of the drilling information;

[0079] Step 4: The control unit controls the moving drive assembly to contract a distance corresponding to the bell mouth radius information according to the bell mouth radius information of the drilling information;

[0080] Step 5: The control unit generates recovery information according to the start information and sends the recovery information to the cleaning component, and the recovery information is used to control the cleaning component to start.

[0081] Compared with the prior art, the present invention has the following beneficial effects:

[0082] 1. Through the setting of the drilling unit in the present invention, the radius inside the drill hole increases with the depth, so that the impact force generated by the blasting is sufficiently released before impacting the medium on the hole wall, which is conducive to improving the blasting effect. While drilling, the cleaning component is started, and the cleaning component can clean the crushed stones while drilling, which is conducive to synchronously cleaning the crushed stones inside the drill hole, avoiding the remaining of crushed stones inside the drill hole, and thus conducive to stabilizing the blasting efficiency and achieving the expected rock breaking effect.

[0083] 2. Through the setting of the first spring in the present invention, it is conducive to promoting the flipping of the first flipping end and the second flipping end, and avoiding the situation that it is difficult to flip due to the abutment of the first flipping end and the second flipping end in the initial state.

[0084] 3. Through the setting of the movable connecting cylinder and the elastic communication mechanism in the present invention, the air flow flows into the drill hole, and the impact force of the air flow drives the movement of the crushed stones inside the drill hole, which is conducive to driving the crushed stones into the range of the negative pressure air flow by the acting force of the impact air flow, thus facilitating the recovery of the crushed stones, improving the recovery effect of the crushed stones, and further improving the subsequent blasting effect inside the drill hole.

[0096] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0097] As Figures 1 to 9 shown, a drilling and blasting operation system includes:

[0098] A measurement and hole layout design unit, which is used to collect the information of the blasting area boundary and key points through a high-precision GPS measurement terminal, and after uploading the information to the server, perform hole layout design according to the blasting area range to generate a hole position design drawing, including information such as hole numbers, positions, depths, etc.;

[0099] A drilling unit, which is used to drill a flared hole at the position where a hole needs to be formed according to the drilling requirements, and clean the crushed stones generated during drilling in real time during the drilling process, so as to automatically clean the hole after drilling is completed, and the data is automatically uploaded to the server after drilling is completed;

[0100] A charging unit, which is used to fill the explosive into the blast hole according to the design requirements, and use gun clay or other materials to plug it after charging to prevent gas leakage;

[0101] The initiating unit is used for initiating by means of electric initiation or detonating cord initiation, and monitors the initiation situation through monitoring.

[0102] As an optional embodiment, the drilling unit includes:

[0103] A bracket 1, on which a housing 2 is installed;

[0104] A cylinder 10, fixed on the bracket 1, and pushes the housing 2 to move through a telescopic rod;

[0105] A rotating cylinder 3, rotatably installed at the end of the housing 2;

[0106] A first motor 301, fixed inside the housing 2, and drives the rotating cylinder 3 to rotate through an output shaft;

[0107] A plurality of second flipping ends 402, flip - installed at the end of the rotating cylinder 3 in a circumferential array;

[0108] A plurality of first flipping ends 401, arranged in one - to - one correspondence with the second flipping ends 402, and one end of each first flipping end 401 is respectively rotatably installed at one end of each second flipping end 402 away from the rotating cylinder 3;

[0109] A drill bit 4, and the other ends of all the first flipping ends 401 are flip - connected to the drill bit 4;

[0110] A moving drive assembly, installed between the drill bit 4 and the rotating cylinder 3, and used for driving the drill bit 4 to linearly move relative to the rotating cylinder 3;

[0111] A cleaning assembly, installed between the drill bit 4 and the rotating cylinder 3, and used for cleaning the generated crushed stones while the drill bit 4 is drilling;

[0112] In existing blasting, it is necessary to drill holes in the medium first, and then fill the holes with explosives. Traditional straight - hole blasting drilling is easy to drill, but the impact force generated by the ignition of explosives mainly rushes out along the direction of the hole opening, and has high requirements for the plugging of the hole opening. If the hole opening is not plugged tightly, the impact force of blasting will be weakened. Therefore, a trumpet - shaped hole with a diameter increasing with depth is adopted, so that the impact force generated by blasting is fully released before impacting the medium on the hole wall; however, the trumpet - shaped hole is inconvenient to drill, and after drilling, the residual crushed stone particles inside are difficult to take out due to the inward offset of the trumpet - shaped hole. If the residual crushed stones inside the drilled hole are not cleaned up, it will cause the explosive to not be in full contact with the hole wall, affecting the effective transfer of the explosive energy, thereby reducing the blasting efficiency and failing to achieve the expected rock - breaking effect;

[0113] This embodiment of the present invention can solve the above problems. The specific implementation is as follows. When drilling is required, the operator holds the bracket 1 by hand or fixes the bracket 1 on the ground, aligning the drill bit 4 with the position where drilling is needed. Subsequently, the first motor 301 is started. After the first motor 301 is started, it drives the connected rotating cylinder 3 to rotate through the output shaft. After the rotating cylinder 3 rotates, it drives the second flipping end 402 connected thereto to revolve around the rotating cylinder 3. After the second flipping end 402 revolves, it drives the first flipping end 401 rotatably connected thereto to revolve around the rotating cylinder 3. After the first flipping end 401 revolves, it drives the drill bit 4 to rotate, thereby drilling the position where drilling is needed through the rotation of the drill bit 4 and the first flipping end 401 and the second flipping end 402. After the cylinder 10 is started, it can drive the connected housing 2 to move, thereby driving the drill bit 4 to move and enabling drilling to a specified depth. After drilling to the specified depth, the moving drive assembly is started. The moving drive assembly drives the drill bit 4 to move in the direction of the rotating cylinder 3, shortening the position between the rotating cylinder 3 and the drill bit 4, thereby driving the first flipping end 401 and the second flipping end 402 to flip, so that the first flipping end 401 and the second flipping end 402 flip and unfold, forming a trumpet-shaped hole between the first flipping end 401 and the second flipping end 402. Thus, the drilling radius inside the drill hole is enlarged by the unfolded first flipping end 401 and the second flipping end 402, which is beneficial to increasing the radius of the drill hole with the increase of depth, enabling the impact force generated by blasting to be sufficiently released before impacting the medium on the hole wall, thereby being beneficial to improving the blasting effect;

[0114] During drilling, the cleaning assembly is started. The cleaning assembly can clean the crushed stones while drilling, which is beneficial to synchronously cleaning the crushed stones inside the drill hole, beneficial to preventing the crushed stones from remaining inside the drill hole, and thus beneficial to stabilizing the blasting efficiency and achieving the expected rock breaking effect;

[0115] Polishing particles 403 are provided on the outer walls of the first flipping end 401, the second flipping end 402, and the drill bit 4, which is beneficial to improving the drilling efficiency.

[0116] As an alternative embodiment, the moving drive assembly includes:

[0117] A second motor 5, fixed inside the rotating cylinder 3 through a first mounting shell 501;

[0118] A screw rod 503, rotatably installed at the end of the rotating cylinder 3. The output shaft of the second motor 5 drives the screw rod 503 to rotate through a rotating shaft 502;

[0119] A threaded sleeve 504, rotatably installed at the end of the drill bit 4, and the threaded sleeve 504 is threadedly connected to the screw rod 503;

[0120] After the second motor 5 starts, it drives the rotating shaft 502 connected thereto to rotate through the output shaft. After the rotating shaft 502 rotates, it drives the screw rod 503 connected thereto to rotate. After the screw rod 503 rotates, it drives the threaded sleeve 504 threadedly connected thereto to move. The threaded sleeve 504 drives the drill bit 4 to move, thereby adjusting the distance between the drill bit 4 and the rotating cylinder 3, so as to adjust the flipping angle between the first flipping end 401 and the second flipping end 402, and thus adjust the outward expansion distance inside the drill hole, so that drilling operations with different internal diameters can be performed according to the needs of the drill hole.

[0121] As an optional embodiment, the cleaning assembly includes:

[0122] An air chamber 6, fixed on the outer wall of the rotating cylinder 3;

[0123] A negative pressure pump 602, fixed on the outer wall of the housing 2 through a second mounting shell 603;

[0124] A negative pressure pipe 601, with both ends fixedly connected and communicated with the negative pressure pump 602 and the air chamber 6 respectively. An electromagnetic valve 604 is fixed inside the negative pressure pipe 601;

[0125] A filter frame 605, fixed on the inner wall of the air chamber 6, and the filter frame 605 covers the end opening of the negative pressure pipe 601;

[0126] An inner cavity 607, opened inside the rotating cylinder 3;

[0127] A first through opening 606, through-opened on the inner circumferential side wall of the air chamber 6;

[0129] A plurality of first insertion pipes 608, fixed on the end of the rotating cylinder 3 in a circumferential array, and all are communicated with the inner cavity 607;

[0130] A plurality of second insertion pipes 609, respectively sealingly and slidably inserted into each first insertion pipe 608 through one end, and the other ends are all communicated with a recovery cavity 610 opened inside the drill bit 4;

[0131] A plurality of first openings 611, arranged in a circumferential array on the side wall of the drill bit 4, and communicated with the recovery cavity 610;

[0132] After the negative pressure pump 602 starts, it drives the airflow to flow. Through the negative pressure pipe 601, a negative pressure is formed inside the air chamber 6 connected to it. Thus, under the action of the negative pressure, the airflow is driven to flow along the trajectory of the first opening 611, the recovery chamber 610, the second insertion pipe 609, the first insertion pipe 608, the inner cavity 607, the second opening 613, the first through hole 606, and the air chamber 6. Thereby, the crushed stones are driven to flow into the air chamber 6 with the airflow. The settings of the second opening 613 and the first through hole 606 enable the second opening 613 to rotate when the rotating cylinder 3 rotates. After the second opening 613 rotates, it remains connected to the first through hole 606, thus remaining connected to the air chamber 6. When the crushed stones enter the air chamber 6, they are retained inside the air chamber 6 under the filtering action of the filter frame 605, while the airflow passes through the negative pressure pipe 601 and is discharged, thereby realizing the recovery of the crushed stones;

[0133] There are two openings in the negative pressure pipe 601, which are respectively connected to both ends inside the air chamber 6. By setting the solenoid valve 604, the two openings of the negative pressure pipe 601 can be switched when the solenoid valve 604 is switched, thereby switching the airflow flow position. This is beneficial for avoiding the situation where the airflow drives the crushed stones to accumulate in the same position, causing blockage inside the air chamber 6. Thus, it is beneficial to clean the crushed stones generated during drilling while drilling, which is beneficial for improving the drilling efficiency and the effect of explosion operations inside the drill hole;

[0134] A first guiding block 612 is provided at the end of the rotating cylinder 3 to guide the airflow and the crushed stones, which is beneficial for improving the fluidity of the crushed stone recovery and avoiding the situation where the crushed stone recovery is blocked and affects the recovery efficiency.

[0135] As an alternative embodiment, the cleaning assembly further includes:

[0136] Multiple negative pressure ports 7 are respectively penetrated and opened on the side walls of each second insertion pipe 609, and the negative pressure ports 7 are blocked by the first insertion pipe 608;

[0137] Multiple communication ports 701 are respectively penetrated and opened on the side walls of each first insertion pipe 608, and the communication ports 701 are blocked by the second insertion pipe 609. When the second insertion pipe 609 moves relative to the first insertion pipe 608, the negative pressure ports 7 move past the communication ports 701 to form a connection;

[0138] When adjusting the position of the drill bit 4, the movement of the drill bit 4 drives the movement of the second insertion pipe 609 connected thereto. The second insertion pipe 609 drives the negative pressure port 7 to move relative to the communication port 701. When the negative pressure port 7 moves to the position of the communication port 701, communication is generated between the negative pressure port 7 and the communication port 701. At this time, the first flipping end 401 and the second flipping end 402 are in the flipped state, so that a gap is exposed between the first flipping end 401 and the second flipping end 402, enabling crushed stones to enter the interior through the gap exposed between the first flipping end 401 and the second flipping end 402, and then entering the interior of the second insertion pipe 609 along the position where the negative pressure port 7 is communicated with the communication port 701. Thus, the crushed stones are recycled under the action of the airflow, which is beneficial to increasing the recycling positions of the crushed stones and thus beneficial to improving the recycling efficiency of the crushed stones;

[0139] The long-distance setting of the communication port 701 enables the negative pressure port 7 to be in communication with the communication port 701 when the drill bit 4 moves within a certain range, so that within a certain movement range, the recycling effect of the crushed stones can be maintained, which is beneficial to improving the recycling efficiency of the crushed stones.

[0140] As an alternative embodiment, it further includes:

[0141] A plurality of first springs 801, which are fixedly arranged on the outer wall of the threaded sleeve 504 in a circumferential array;

[0142] A plurality of support plates 8, which are respectively fixed to one end of each first spring 801 facing away from the threaded sleeve 504;

[0143] A plurality of telescopic sleeves 802, which are respectively sleeved on the outer ring of each first spring 801, and both ends of the telescopic sleeve 802 are fixedly connected to the support plate 8 and the outer wall of the threaded sleeve 504 respectively;

[0144] When the drill bit 4 moves towards the direction of the rotating cylinder 3, the first spring 801 can push the support plate 8 to move under the action of its own elastic force. The movement of the support plate 8 pushes the first flipping end 401 and the second flipping end 402 to flip. Thus, when the first flipping end 401 and the second flipping end 402 are flush in the initial state, the support plate 8 can push the first flipping end 401 and the second flipping end 402 to flip, which is beneficial to promoting the flipping of the first flipping end 401 and the second flipping end 402 and beneficial to avoiding the situation that it is difficult to flip due to the abutment of the first flipping end 401 and the second flipping end 402 in the initial state.

[0145] As an alternative embodiment, it further includes:

[0146] A movable connection cylinder 9, which is fixed inside the inner cavity 607 through a limit track 903;

[0147] The cross bar 901 is fixed inside one end of the movable connection cylinder 9 facing the second insertion pipe 609. When one of the second insertion pipes 609 moves towards the movable connection cylinder 9, it inserts into the inside of the movable connection cylinder 9 and pushes the movable connection cylinder 9 to move through the cross bar 901.

[0148] A plurality of third openings 902 are respectively formed on the side walls of the movable connection cylinder 9.

[0149] The air flow frame 906 is fixed inside the inner cavity 607.

[0151] The elastic connection mechanism is installed between the movable connection cylinder 9 and the air flow frame 906, and is used to connect the air flow frame 906 after the second insertion pipe 609 pushes the movable connection cylinder 9 to move.

[0152] The guiding bin 915 is fixed inside the recovery cavity 610. One end is in communication with the movable connection cylinder 9, the first insertion pipe 608, and the second insertion pipe 609, and the other end is in communication with one of the first openings 611.

[0153] The negative pressure pump 602 conveys the air flow to the air flow frame 906 through the rotation and connection mechanism. After the drill bit 4 moves a certain distance, it drives the second insertion pipe 609 to move a certain distance, so that the second insertion pipe 609 moves through the first insertion pipe 608 and then penetrates out, causing the second insertion pipe 609 to push the cross bar 901, and then pushing the movable connection cylinder 9 through the cross bar 901, so that the movable connection cylinder 9 moves along the track of the limit track 903, gradually pushing the movable connection cylinder 9 towards the air flow frame 906, and then pushing the elastic connection mechanism, so that the air flow frame 906 is connected to the movable connection cylinder 9. At this time, the air flow inside the air flow frame 906 is conveyed along the movable connection cylinder 9 to the connected first insertion pipe 608 and second insertion pipe 609, so that the air flow flows along the first insertion pipe 608 and then passes through the guiding bin 915 and is discharged from the first opening 611 communicated therewith, so that the air flow flows into the inside of the drill hole. The impact force of the air flow drives the crushed stones inside the drill hole to move, which is beneficial to driving the crushed stones into the range of the negative pressure air flow by the acting force of the impact air flow, which is beneficial to driving the recovery of the crushed stones, so as to improve the recovery effect of the crushed stones, and is beneficial to improving the subsequent explosion effect inside the drill hole.

[0154] As an alternative embodiment, the rotation and connection mechanism includes:

[0155] The annular bin 910 is fixed inside the inner cavity 607, and a channel 911 is provided at the center of the annular bin 910.

[0160] The negative - pressure pump 602 is connected to the connecting bin 912 through the air inlet pipe 914. The connecting bin 912 is connected to the annular bin 910 through the second through - opening 913. The channel 911 in the inner circle of the annular bin 910 can allow the air flow to drive the crushed stones through. The annular bin 910 is connected to the connecting cylinder 909, and the connecting cylinder 909 is connected to the air flow frame 906. Thus, the air flow is driven to enter the air flow frame 906 from the output end of the negative - pressure pump 602. When the rotating cylinder 3 rotates, it drives the annular bin 910 and the second through - opening 913 to rotate, so as to maintain the connection with the connecting bin 912 through the second through - openings 913 arranged in a circumferential array.

[0165] The second guiding block 904 is fixed at the end of the moving connection cylinder 9;

[0166] The second insertion pipe 609 pushes the cross - bar 901 to drive the moving connection cylinder 9 to move, so that the moving connection cylinder 9 squeezes the second spring 905. The second spring 905 pushes the baffle plate 907, so that the baffle plate 907 moves out of the ventilation opening. The baffle plate 907 squeezes the third spring 908 into the interior of the air flow frame 906 until the moving connection cylinder 9 gradually inserts into the interior of the air flow frame 906. The moving connection cylinder 9 is communicated with the interior of the air flow frame 906 through the third opening 902, so that the air flow can pass through the moving connection cylinder 9 and enter the interior of the first insertion pipe 608, thus driving the air flow to enter the interior of the first insertion pipe 608 to form an air flow impact after the drill bit 4 moves;

[0167] The second guiding block 904 can guide the flow of the crushed stones driven by the negative pressure air flow when the moving connection cylinder 9 is not connected to the air flow frame 906.

[0168] Such as Figure 10 An information management method for a drilling and blasting operation system as shown. A control unit is installed on the support 1, and the control unit includes a user terminal. The management method includes the following steps:

[0169] Step 1: The control unit obtains drilling information from the user terminal. The drilling information includes drilling depth information and flare radius information.

[0170] Step 2: The control unit controls the first motor 301 to start according to the start information obtained from the user terminal.

[0171] Step 3: The control unit controls the cylinder 10 to move the housing 2 by a distance corresponding to the drilling depth according to the drilling depth information of the drilling information.

[0172] Step 4: The control unit controls the moving drive assembly to contract by a distance corresponding to the flare radius information according to the flare radius information of the drilling information.

[0173] Step 5: The control unit generates recovery information according to the start information and sends the recovery information to the cleaning component. The recovery information is used to control the cleaning component to start.

[0174] Working principle of the present invention: When drilling is required, the operator holds the support 1 or fixes the support 1 on the ground so that the drill bit 4 is aligned with the position where drilling is to be carried out. Subsequently, the first motor 301 is started. After the first motor 301 is started, it drives the connected rotating cylinder 3 to rotate through the output shaft. After the rotating cylinder 3 rotates, it drives the connected second flipping end 402 to revolve around the rotating cylinder 3. After the second flipping end 402 revolves, it drives the first flipping end 401 rotatably connected thereto to revolve around the rotating cylinder 3. After the first flipping end 401 revolves, it drives the drill bit 4 to rotate. Thus, drilling is carried out on the position where drilling is required through the rotation of the drill bit 4 and the first flipping end 401 and the second flipping end 402. After the cylinder 10 is started, it can drive the connected housing 2 to move, thereby driving the drill bit 4 to move and enabling drilling to a specified depth. After drilling to the specified depth, the moving drive assembly is started. The moving drive assembly drives the drill bit 4 to move in the direction of the rotating cylinder 3, shortening the position between the rotating cylinder 3 and the drill bit 4, thereby driving the first flipping end 401 and the second flipping end 402 to flip, so that the first flipping end 401 and the second flipping end 402 flip and expand, forming a trumpet-shaped hole between the first flipping end 401 and the second flipping end 402. Thus, the drilling radius inside the drilling is enlarged through the expanded first flipping end 401 and the second flipping end 402, which is beneficial to increasing the radius of the drilling inside with the increase of depth, enabling the impact force generated by blasting to be sufficiently released before impacting the medium on the hole wall, thereby being beneficial to improving the blasting effect;

[0175] While drilling, the cleaning assembly is started. The cleaning assembly can clean the crushed stones while drilling, which is beneficial to synchronously cleaning the crushed stones inside the drilling, beneficial to avoiding the retention of crushed stones inside the drilling, and thus beneficial to stabilizing the blasting efficiency and achieving the expected rock breaking effect;

[0176] The outer walls of the first flipping end 401, the second flipping end 402, and the drill bit 4 are all provided with abrasive particles 403, which is beneficial to improving the drilling efficiency.

[0177] The above shows and describes the basic principle, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
