Figure 2 As shown, the water spray device 400 includes: at least two spray heads 401, at least two spray heads 401 are circumferentially arranged along the circumferential surface of the power device 100; and a water spray power assembly 402, which is configured to drive at least two spray heads 401 to spray water under the control of the controller.

[0036] In one possible implementation, Figure 3 A structural schematic diagram of another rotary drilling rig provided for this application is shown in FIG. Figure 3As shown, the water spray power assembly 402 includes: a water tank 403; a water pump 404, the water suction port of the water pump 404 is connected to the water tank 403, and the water pump 404 is connected to the controller in communication; a connecting pipe 405, the first end of the connecting pipe 405 is connected to the water outlet of the water pump 404, and the second end of the connecting pipe 405 is connected to at least two nozzles 401. When the controller determines that the rotary drilling rig is in a state of throwing out according to the power parameters and the distance value between the bottom surface of the drill bucket 200 and the ground, and the water spray device 400 needs to spray water, the controller controls the water pump 404 to absorb water from the water tank 403, and the water passes through the connecting pipe 405 to the at least two nozzles 401, and the water is sprayed from the at least two nozzles 401.

[0037] In one possible implementation, Figure 4 A schematic diagram of a top view of a dust suppression device for a rotary drilling rig provided in the present application, in which a nozzle is arranged in the circumferential direction of a power device, as shown in FIG. Figure 4 As shown, at least two nozzles 401 are evenly arranged along the circumferential surface of the power device 100; the water mist barrier formed by at least two nozzles 401 above the drill bucket 200 can evenly cover the drill bit of the drill bucket, effectively reducing the diffusion and propagation of dust generated by the drill bucket during the swinging process.

[0038] In one possible implementation, Figure 5 This is a schematic diagram of a top view of another dust suppression device for a rotary drilling rig in which a nozzle is arranged in the circumferential direction of a power device. Figure 5 As shown, the number of at least two nozzles 401 included in the water spray device 400 is an even number, and the at least two nozzles 401 are symmetrically arranged with the first straight line 406 as the symmetry axis; wherein the first straight line 406 is parallel to the axial direction of the power device 100 and passes through the center point of the power device 100. The at least two nozzles 401 are symmetrically arranged, and the water sprayed by the at least two nozzles 401 forms a symmetrical water mist barrier above the drill bit of the drill bucket 200, which more accurately and effectively reduces the dust generated by the drill bucket during the swinging process.

[0039] In one possible implementation, Figure 4 As shown, the water spray device 400 includes at least 4 nozzles, and the 4 nozzles are evenly and symmetrically arranged on the circumferential surface of the power device 100; when the 4 nozzles 401 spray water, a uniform and symmetrical water mist barrier is formed above the drill bit of the drill bucket 200, and the water mist barrier can cover the drill bit of the drill bucket 200 more comprehensively, effectively intercepting the dust generated during the swinging process of the rotary drilling rig, thereby improving the efficiency of dust reduction.

[0040] In the second aspect of this application, Figure 6 Another schematic diagram of the rotary drilling rig structure provided for this application is as follows: Figure 6As shown, the rotary drilling rig includes: a drill rod 600; a power device 100 connected to the drill rod 600; a drill bucket 200 arranged at the end of the drill rod 600; a mast 500, on which the power device 100 is arranged, and the power device 100 can move relative to the mast 500 along the length direction of the mast 500; and a dust reduction device, the structure of which adopts the structure of the dust reduction device described above. The power device 100 drives the drill bucket 200 to work, and when the drill bucket 200 is in the swinging state, the dust reduction device is used to reduce the dust generated by the drill bucket 200 during the swinging process, prevent the dust from spreading during the swinging process, and thus reduce the pollution to the environment during the swinging process.

[0041] In the third aspect of this application, Figure 7 A schematic diagram of a dust control method provided in this application is shown in FIG. Figure 7 As shown, the present application provides a dust reduction control method for controlling a dust reduction device of a rotary drilling rig, comprising the following steps:

[0042] Step S101, obtaining the distance value between the bottom surface of the drill bucket and the ground and the power parameters of the power device;

[0043] When obtaining the distance value between the bottom surface of the drill bucket and the ground, the ground is used as a reference line to limit the distance value between the bottom surface of the drill bucket and the ground; for example, when the bottom surface of the drill bucket is above the ground, the distance value between the bottom surface of the drill bucket and the ground is set to be less than zero; when the bottom surface of the drill bucket is below the ground, the distance value between the bottom surface of the drill bucket and the ground is set to be greater than zero; or, when the bottom surface of the drill bucket is above the ground, the distance value between the bottom surface of the drill bucket and the ground is set to be greater than zero; when the bottom surface of the drill bucket is below the ground, the distance value between the bottom surface of the drill bucket and the ground is set to be less than zero;

[0044] It should be noted that the setting method of the distance value between the bottom surface of the drill bucket and the ground can adopt the above-mentioned form, or can adopt other setting methods. For example, no matter whether the bottom surface of the drill bucket is above or below the ground, taking a certain horizontal plane above the ground as the reference plane, the distance value between the bottom surface of the drill bucket and the ground is less than zero. Therefore, as long as it can be judged whether the bottom surface of the drill bucket is above or below the ground based on the distance value between the bottom surface of the drill bucket and the ground, the present application does not limit the setting method of the distance value between the bottom surface of the drill bucket and the ground.

[0045] Step S102, obtaining the working state of the rotary drilling rig according to the distance value between the bottom surface of the drill bucket and the ground and the power parameters of the power device, and generating control information according to the working state of the rotary drilling rig, the control information is used to control the opening or closing of the water spraying device.

[0046] Step S102 is to obtain whether the drill bucket is in a swinging state through the distance value between the bottom surface of the drill bucket and the ground and the power parameters of the power device. When it is in the swinging state, control information for controlling the water spraying device to open is generated, so that the water spraying device sprays water under the action of the control information to complete the water spraying work; when it is not in the swinging state, control information for closing the water spraying device is generated, so as to control the water spraying device to close.

[0047] The present application determines the working state of the rotary drilling rig based on the distance value between the bottom surface of the drill bucket and the ground and the power parameters of the power unit; when it is determined that the rotary drilling rig is in the swinging state, control information for controlling the water spraying device to spray water is generated, so that the water spraying device starts to spray water, forming a spray barrier above the drill bucket, reducing the dust generated by the rotary drilling rig during the swinging process and reducing the pollution of the dust to the surrounding environment; when it is determined that the rotary drilling rig has completed the swinging, control information for controlling the water spraying device to be turned off is generated, so that the water spraying device stops spraying water.

[0048] In one possible implementation, Figure 8 A schematic diagram of another dust control method for this application is shown below: Figure 8 As shown, when the distance value between the bottom surface of the drill bucket and the ground in step S101 is set to be less than zero, the bottom surface of the drill bucket is located above the ground; then step S102 (obtaining the working state of the rotary drilling rig according to the distance value between the bottom surface of the drill bucket and the ground and the power parameters of the power device, and generating control information according to the working state of the rotary drilling rig) specifically includes the following steps:

[0049] Step S1021: determining whether the distance value between the bottom surface of the drill bucket and the ground is less than zero;

[0050] When the judgment result in step S1021 is yes, the distance value between the bottom surface of the drill bucket and the ground is less than zero, and the bottom surface of the drill bucket is above the ground. At this time, it can only be concluded that the bottom surface of the drill bucket is above the ground, and it is still impossible to determine whether the working state of the drill bucket is in the swinging state. Therefore, when the judgment result in step S1021 is yes, step S1022 is executed, that is,

[0051] Step S1022: determining whether the power parameter of the power device is less than a preset power parameter. When the power parameter of the power device is less than the preset power parameter, it can be determined that the power device is driving the drill bucket to throw out the soil or other materials in the drill bucket, that is, the working state of the drill bucket is in the throwing state;

[0052] Step S1023: generating first control information, the first control information is used to control the water spray device to start;

[0053] When step S1021 and step S1022 determine that the working state of the drill bucket is in the swinging working state, the first control information is generated. The first control information is used to control the water spraying device to start. After receiving the first control information, the water spraying device starts spraying water to form a spray barrier above the drill bucket, thereby reducing the dust generated by the rotary drilling rig during the swinging process and reducing the pollution of the dust to the surrounding environment.

[0054] When the judgment result in step S1021 is no, that is, the distance value between the lower bottom surface of the drill bucket and the ground is greater than zero, at this time, the lower bottom surface of the drill bucket is located below the ground, and the drill bucket can judge that the working state of the drill bucket is definitely not in the swinging state. Therefore, during the working process of the drill bucket, continue to obtain the distance value between the lower bottom surface of the drill bucket and the ground, that is, execute steps S101-step S1021, until the judgment result in step S1021 is yes, execute step S1022.

[0055] Similarly, when the judgment result in step S1022 is no, that is, the power parameter of the power device is greater than the preset power parameter, it can be judged that the working state of the drill bucket is not in the swinging state. Therefore, during the working process of the drill bucket, continue to obtain the power parameters of the drill bucket and subsequent steps, that is, execute steps S101-S1022, until the judgment result in step S1022 is yes, execute step S1023.

[0056] Similarly, if the distance value between the lower bottom surface of the drill bucket and the ground is set to be greater than zero in step S101, the lower bottom surface of the drill bucket is above the ground. Then, when the distance value between the lower bottom surface of the drill bucket and the ground is greater than zero in step S1021, the lower bottom surface of the drill bucket is above the ground, and step S1022 is executed; when the distance value between the lower bottom surface of the drill bucket and the ground is less than zero, the lower bottom surface of the drill bucket is below the ground, and the process returns to step S101.

[0057] In one possible implementation, Fig. 9 As shown, another dust control method flow chart of the present application is as follows: Fig. 9 As shown, the power parameter includes the alternating time of forward and reverse rotation when the power device rotates, and the preset power parameter includes the preset time; at the same time, the distance between the bottom surface of the drill bucket and the ground is set to be less than zero, and the bottom surface of the drill bucket is above the ground; Fig. 9 As shown, the dust control method specifically includes the following steps:

[0058] Step S201, obtaining the distance value between the bottom surface of the drill bucket and the ground and the power parameters of the power device;

[0059] Step S202, determining whether the distance value between the bottom surface of the drill bucket and the ground is less than zero;

[0060] When the judgment result in step S202 is yes, the distance value between the bottom surface of the drill bucket and the ground is less than zero, and the bottom surface of the drill bucket is above the ground. At this time, it can only be concluded that the bottom surface of the drill bucket is above the ground, and it is still impossible to determine whether the working state of the drill bucket is in the swing state. Therefore, when the judgment result in step S202 is yes, step S203 needs to be executed, that is,

[0061] Step S203, determining whether the duration of the alternating forward and reverse rotations of the power device is less than a preset duration; when the duration of the alternating forward and reverse rotations of the power device is less than the preset duration, it can be determined that the power device is driving the drill bucket to throw out the soil or other materials in the drill bucket, and at this time, the working state of the drill bucket is in a throwing state;

[0062] Step S204, generating first control information, the first control information is used to control the water spray device to start;

[0063] When step S202 and step S203 determine that the working state of the drill bucket is in the swinging working state, the first control information is generated, and the first control information is used to control the water spraying device to start. After receiving the first control information, the water spraying device starts spraying water to form a spray barrier above the drill bucket, thereby reducing the dust generated by the rotary drilling rig during the swinging process and reducing the pollution of the dust to the surrounding environment; when the working state of the drill bucket is in the completed swinging state, the closing control information is generated to control the water spraying device to close.

[0064] When the judgment result in step S202 is no, that is, the distance value between the lower bottom surface of the drill bucket and the ground is greater than zero, at this time, the lower bottom surface of the drill bucket is located below the ground, and it can be judged that the working state of the drill bucket is not necessarily in the swinging state. Therefore, during the working process of the drill bucket, continue to obtain the distance value between the lower bottom surface of the drill bucket and the ground, and continue to execute steps S201-step S202 until the judgment result in step S202 is yes, and then execute step S203.

[0065] Similarly, when the judgment result in step S203 is no, that is, the alternating time length of the forward and reverse rotation of the power device is greater than the preset time length, it can be judged that the working state of the drill bucket is not in the swinging state. Therefore, during the working process of the drill bucket, continue to obtain the alternating time length of the forward and reverse rotation of the power device and the subsequent steps, that is, execute steps S201-S203, until the judgment result in step S203 is yes, execute step S204.

[0066] The power parameters include the duration of the alternating forward and reverse rotations of the power unit. When the drill bucket performs the throwing action, the power unit drives the drill bucket forward and reverse rotations, and the attachments on the drill bucket are thrown out under the action of the inertial force of the forward and reverse rotations. If the duration of the alternating forward and reverse rotations of the power unit is less than the preset duration, it means that the drill bucket needs a greater inertial force at this time to throw out the attachments, so as to remove the attachments on the drill bucket more quickly and effectively.

[0067] The fourth aspect of this application is: Fig.10 A dust suppression controller working principle diagram provided for this application, such as Fig.10 As shown, a dust reduction controller includes: a data acquisition module 1, which is used to acquire the distance value between the bottom surface of the drill bucket and the ground and the power parameters of the power device; a control information generation module 2, which is used to acquire the working state of the rotary drilling rig according to the distance value between the bottom surface of the drill bucket and the ground and the power parameters of the power device, and generate control information according to the working state of the rotary drilling rig, and the control information is used to control the opening or closing of the water spray device 400. The working state of the drill bucket is judged according to the distance value between the bottom surface of the drill bucket and the ground and the power parameters of the power device acquired by the data acquisition module; when the working state of the drill bucket is in the swing state, the control information generation module generates control information, and the control information is used to control the water spray device to start, and the water spray device starts to spray water according to the control information, forming a spray barrier above the drill bit of the drill bucket, and reducing the dust generated by the swing state of the drill bucket; when the working state of the drill bucket is not in the swing state, the control information generation module generates control information, and the control information is used to control the water spray device to close.
