[0058] The working principle and beneficial effects of the above technical solution are:

[0059] A three-arm drilling vehicle for drilling, anchoring and probing in coal mines has three drill arm assemblies arranged on a vehicle body 1, and the three drill arm assemblies can be controlled separately; a first adjusting part 2, a second adjusting part 3 and a third adjusting part 4 are arranged on the drill arm assembly, and during drilling, the drill arm part 5 is adjusted to a preset position and angle through the coordinated action of the three adjusting parts, so that the drill rod 8 is directly opposite to the position where a hole needs to be drilled; then the anchor drill rig 6 is started to drive the drill rod 8 to rotate at a high speed and move forward at the same time to perform the drilling operation; the end of the drill rod 8 is kept stable by arranging a clamping seat 7; a rotating nozzle seat 9 is arranged on the clamping seat 7, and during the drilling process, the water flow in the water tank is transported to the spray plate 10 through a pipeline through a pump body, and the spray plate 10 rotates up and down at the same time, so that the water mist is evenly sprayed on the drill rod 8 and the drilling position to reduce dust.

[0060] Through the above structural design, a three-arm drilling vehicle for drilling, anchoring and probing in coal mines is provided, which adopts three drill arm assemblies that are individually controlled, and can perform drilling operations on three positions at the same time, thereby improving the efficiency of the drilling vehicle; a rotating nozzle seat 9 is arranged on the clamping seat 7, so that the spray plate 10 is aligned with the drilling position and rotates up and down to spray, thereby expanding the spray range, effectively reducing the dust at the drilling position, facilitating the operator to observe the drilling position, and effectively utilizing the spray water to reduce the waste of water resources.

[0061] Example 2

[0062] like Figure 1 , 2 As shown, on the basis of the above-mentioned embodiment 1, the first adjusting part 2 includes: a first electric turntable 17, a first hydraulic strut 11 and a second hydraulic strut 12, the first electric turntable 17 is connected to the vehicle body 1, the bottom end of the first hydraulic strut 11 and the bottom end of the second hydraulic strut 12 are both hinged to the first electric turntable 17, and the top end of the first hydraulic strut 11 is hinged to the lower part of the second hydraulic strut 12.

[0063] The second adjusting part 3 includes a rotating shaft 13 , which is rotatably connected to the top end of the second hydraulic strut 11 , and one end of the rotating shaft 13 is connected to the output end of the motor, which is installed on the second hydraulic strut 11 .

[0064] The third adjusting part 4 includes: a second electric turntable 14 , which is rotatably connected to the top of the rotating shaft 13 , and the top of the second electric turntable 14 is connected to the drill arm part 5 .

[0065] The working principle and beneficial effects of the above technical solution are:

[0066] When the first adjustment part 2 is in use, the controller starts the first electric turntable 17 of the three drill arm assemblies respectively, so that the three drill arm assemblies are separated from each other and rotated horizontally to a preset angle; the first hydraulic support rod 11 is started to extend it, and under the support of the first hydraulic support rod 11, the second hydraulic support rod 12 rotates upward by a preset angle; the second hydraulic support rod 12 is started to extend or contract to adjust the height of the second adjustment part 3, the third adjustment part 4 and the drill arm part 5 above.

[0067] When the second adjustment part 3 is in use, the controller starts the motor to drive the rotating shaft 13 to rotate, thereby driving the third adjustment part 4 and the drill arm part 5 to rotate, thereby adjusting the angle of the drill rod 8 .

[0068] When the third adjustment part 4 is in use, the controller starts the second electric turntable 14 to rotate, driving the drill arm part 5 to rotate, thereby adjusting the angle of the drill rod 8 .

[0069] Through the above-mentioned structural design, a first adjusting part 2, a second adjusting part 3 and a third adjusting part 4 are set. When drilling, the drill rod 8 is adjusted to a preset position and the preset height and drilling angle are maintained through the coordinated action of the three adjusting parts. The use of the three adjusting parts effectively expands the adjustment range of the drill rod, so that it can adapt to different drilling and anchoring environments.

[0070] Example 3

[0071] like Figure 1 , 2 As shown, based on the above embodiment 1, the drill arm 5 includes:

[0073] The working principle and beneficial effects of the above technical solution are:

[0074] When the drill arm 5 is in use, the anchor drill 5 is started to drive the drill rod 8 to rotate at high speed, and the electric slide 15 is started to move the fixed plate 16 forward, driving the anchor drill 6 forward, so that the drill rod 8 is fed forward, thereby realizing the drilling operation. The clamping seat 7 is arranged at the end of the electric slide 15 to clamp and guide the drill rod 8, so as to prevent the drill rod 8 from being offset during the drilling process due to its long length, and effectively improve the position accuracy of the drilling.

[0075] Example 4

[0076] like Figure 3-8 As shown, on the basis of the above-mentioned embodiment 1, a support frame 22 is vertically arranged on the rotating nozzle seat 9, the spray plate 10 is arranged in a semi-cylindrical shape, both ends of the spray plate 10 are rotatably connected to the support frame 22, and one end of the rotating shaft of the spray plate 10 is connected to the output end of the driving motor; a plurality of spray holes are evenly arranged on the spray plate 10.

[0077] The working principle and beneficial effects of the above technical solution are:

[0078] When the rotating nozzle seat 9 is in use, the driving motor is started to drive the spray plate 10 to rotate, so that the spray plate 10 rotates up and down. On the one hand, a larger spray surface is formed at the drilling position. After the spray water contacts the dust generated by the drilling, the dust is wetted and can fall to the ground, which is convenient for the staff to observe the drilling position and ensure the safe and accurate drilling process; on the other hand, the dust is reduced from spreading to the surrounding after the water flow impacts the dust; and according to the dust situation, the spray mode can be set to spray from top to bottom to increase the spray pressure of the water flow on the dust, so that the dust can be better settled.

[0079] Example 5

[0080] like Figure 3-8 As shown, based on the above-mentioned embodiment 4, the spray plate 10 includes:

[0081] The fan-shaped plate 24 is connected to the front and rear sides of the spray plate 10, and the cross-sectional size of the fan-shaped plate 24 is larger than the cross-sectional size of the spray plate 10. The fan-shaped guide groove 25 is arranged on the outer side of the fan-shaped plate 24 and the fan-shaped guide groove 25 is arranged corresponding to the edge of the fan-shaped plate 24. The side wall of the fan-shaped guide groove 25 is evenly provided with latch teeth;

[0082] A U-shaped frame 26, the U-shaped frame 26 is arranged to surround the spray plate 10, and both ends of the U-shaped frame 26 extend into the fan-shaped guide groove 25;

[0083] Guide gear 27, guide gear 27 is arranged in fan-shaped guide groove 25 and is rotatably connected with the end of U-shaped frame 26, guide gear 27 is meshed with the teeth of the side wall of fan-shaped guide groove 25, one end of the guide gear 27 shaft is connected with the output end of the gear motor, and the gear motor is installed on U-shaped frame 26;

[0084] The cleaning plate assembly is connected to the inner side of the U-shaped frame 26 through a spring, and the cleaning surface of the cleaning plate assembly is in contact with the surface of the spray plate 10 .

[0085] The working principle and beneficial effects of the above technical solution are:

[0086] The spray plate 10 is provided with a cleaning plate assembly. When in use, the gear motor is started to drive the guide gear 27 to rotate, and the guide gear 27 is meshed with the teeth in the fan-shaped guide groove 25 for transmission. The cleaning plate assembly fits with the spray plate 10 under the action of the spring, which can limit the moving direction of the U-shaped frame 26 so that it does not rotate; that is, the rotation of the guide gear 27 drives the U-shaped frame 26 to move along the spray plate 10 as a whole. When the U-shaped frame 26 moves on the plane of the spray plate 10, the cleaning plate assembly contacts the spray hole to remove dust and particles in the spray hole; when the spray plate 10 performs a spraying operation, the U-shaped frame 26 is moved to the bottom of the spray plate 10 to expose the spray holes on the spray plate 10, so as not to interfere with the spraying operation process.

[0087] Through the above-mentioned structural design, by driving the guide gear 27 to rotate and drive the U-shaped frame 26 to move, and then drive the cleaning plate assembly to move, the cleaning plate assembly can remove the dust and particulate matter attached to the spray plate 10, especially in the spray hole, without manual operation, effectively keeping the spray plate 10 clean, reducing the possibility of clogging the spray hole, and facilitating the next spraying operation; it solves the problem that the dust in the spraying process is impacted by the water flow and diffuses to the surroundings, adheres to the spray plate 10, and causes the spray hole to be blocked, thereby improving the effectiveness of spray dust reduction.

[0089] like Figure 3-8 As shown, based on the above embodiment 5, the cleaning plate assembly includes:

[0090] The adsorption plate 31 and the brush plate 32, the adsorption plate 31 is connected to the inner side of the U-shaped frame 26 by a spring, and the adsorption plate 31 adopts the adsorption form of magnetic attraction or negative pressure suction cup; the brush plate 32 is adsorbed and connected to the adsorption plate 31, and the controller can control the adsorption state of the adsorption plate 31 and the brush plate 32, and the brush plate 32 is provided with bristles for cleaning the spray holes, and the bristles of the brush plate 32 are in contact with the surface of the spray plate 10.

[0091] The working principle and beneficial effects of the above technical solution are:

[0092] When the cleaning plate assembly is in use, the controller starts the adsorption assembly in the adsorption plate 31, putting it in an adsorption state, and adsorbs and installs the brush plate 32 on the adsorption plate 31. When the brush plate 32 moves, the bristles on the brush plate 32 fit the surface of the spray plate 10 and clean as it moves. The bristles can enter the spray hole, thereby cleaning the spray plate 10. When the brush plate 32 moves downward to below the spray plate 10, the dust and particles cleaned fall down.

[0093] Example 7

[0094] like Figure 3-8 As shown, based on the above-mentioned embodiment 6, a brush plate replacement unit is provided on the rotating nozzle seat 9, and the brush plate replacement unit includes:

[0095] A collecting box 41, which is connected to the rotating nozzle seat 9 and is located below the spray plate 10;

[0097] A partition block 43 is connected to an L-shaped bracket 44 on the side of the brush plate box 42. A spring is connected between the partition block 43 and the end of the L-shaped bracket 44. The top of the partition block 43 is set as an inclined surface, and the bottom of the partition block 43 is pressed on the topmost brush plate 32.

[0099] The transfer plate 47, the front and rear ends of the transfer plate 47 are connected to the guide slot 46 through sliding columns, and the transfer plate 47 is provided with the same adsorption component as that on the adsorption plate 31, which can attract the brush plate 32; the side plate 45 is installed with a hydraulic strut, and the two ends of the hydraulic strut are respectively hinged with the side plate 45 and the transfer plate 47, and the hydraulic strut is used to drive the transfer plate 47 to slide along the guide slot 46;

[0100] The flip frame 48, the rotating shaft of the flip frame 48 is connected to the bracket 49, the bracket 49 is connected to the side of the support frame 22 away from the drilling position, the rotating shaft of the flip frame 48 is connected to the output end of the flip motor on the outside of the bracket 49; the flip frame 48 is located on the inner side of the side plate 45, and a receiving platform 50 is provided at the bottom of the flip frame 48. The position of the receiving platform 50 corresponds to the position of the guide slide groove 46, and the receiving platform 50 is provided with the same adsorption component as that on the adsorption plate 31, which can attract the brush plate 32.

[0101] The working principle and beneficial effects of the above technical solution are:

[0102] The adsorption plate 31 has suction force on the brush plate 32, and the adsorption state can be controlled by the controller to adsorb or release the brush plate 32. When the bristles of the brush plate 32 are deformed and worn after being used for a period of time, the spray plate 10 is rotated, and the U-shaped frame 26 is moved above the collection box 41, and the adsorption plate 31 releases the adsorption of the brush plate 32, and the brush plate 32 falls into the collection box 41 under the action of gravity; then the U-shaped frame 26 is moved to the rear side of the spray plate 10, close to the transfer plate 47.

[0103] The transfer plate 47 moves downward to squeeze the inclined surface of the dividing block 43, so that the dividing block 43 is away from the top brush plate 32; the transfer plate 47 absorbs the top brush plate 32, and drives the brush plate 32 to move upward to take it out of the brush plate box 42; after the dividing block 64 loses the pressure of the transfer plate 47, it is reset under the action of the spring and pressed onto the next brush plate 32; that is, every time the transfer plate 47 absorbs a brush plate 32, the brush plate 32 below moves upward under the action of the spring and is separated by the dividing block 64.

[0104] The hydraulic strut is started to extend to drive the transfer plate 47 to move. The transfer plate 47 moves obliquely upward and then horizontally along the guide grooves 46 on both sides to transfer the brush plate 32 to the top of the receiving platform 50 of the flip frame 48. The attraction of the transfer plate 47 to the brush plate 32 is then released, so that the brush plate 32 is placed and adsorbed on the receiving platform 50. The hydraulic strut is then started to retract to drive the transfer plate 68 to move in the opposite direction to the position above the brush plate box 42.

[0105] Start the flip motor to drive the flip frame 48 to rotate to a preset angle, so that the receiving platform 50 of the flip frame 48 is just located on the inner side of the U-shaped frame 26, and the brush plate 32 is in contact with the adsorption plate 31. At this time, the adsorption of the adsorption plate 31 by the receiving platform 50 is released, and the adsorption component of the adsorption plate 31 is started to adsorb the brush plate 32, and then the flip frame 48 is rotated in the opposite direction to reset.

[0106] Through the above-mentioned structural design, the brush plate 32 can be quickly replaced effectively. The controller can jointly control the switching of the adsorption status of each component, and accurately install the brush plate 32 on the adsorption plate 31, thereby reducing the workload of manual replacement of the brush plate 32; it can be automatically carried out during the drilling operation interval without the need to readjust the angle of the drill arm assembly, thereby improving the operation efficiency, ensuring the effective cleaning of the spray plate 10, and extending the service life of the spray plate 10.

[0107] Example 8

[0108] On the basis of the above-mentioned embodiment 7, a protective film is connected to the outer side of the rotating nozzle seat 9 and the support frame 22, the protective film is connected to the spray plate 10, and an opening for the U-shaped frame 26 to pass through is provided at the connection between the protective film and the spray plate 10.

[0109] The working principle and beneficial effects of the above technical solution are:

[0110] By providing the elastic protective film, various components in the rotating nozzle seat 9 can be protected, the dust entering into the structural parts and affecting the transmission can be reduced, and the reliability of the rotating nozzle seat 9 can be improved.

[0111] Example 9

[0112] like Fig. 9 , 10 As shown, on the basis of the above-mentioned embodiment 6, a correction component is provided on the adsorption plate 31 and the brush plate 32, and the correction component includes:

[0113] Positioning plates 51, two positioning plates 51 are symmetrically connected to the side of the brush plate 32 where no bristles are provided;

[0114] Positioning grooves 52, two positioning grooves 52 are symmetrically arranged on one side of the adsorption plate 31 adsorbing the brush plate 32;

[0115] A hinge seat 53, the hinge seat 53 is connected to the positioning groove 52;

[0116] The correcting ring 54 has a middle part connected to the hinge seat 53 and is arranged in a semi-ring shape. One end of the correcting ring 54 close to the center of the positioning groove 52 is connected to a lug 55 and the other end is connected to a correcting plate 56. A return spring 57 is connected between the lug 55 and the positioning groove 52.

[0117] The working principle and beneficial effects of the above technical solution are:

[0118] When the adsorption plate 31 adsorbs the brush plate 32, there is a situation where the brush plate 32 and the adsorption plate 31 are offset in the length direction. When the adsorption plate 31 and the brush plate 32 are adsorbed and connected, the positioning plate 51 of the brush plate 31 enters the positioning groove 52 of the adsorption plate 31 and contacts the correction ring 54. When there is no offset, the positioning plate 51 falls into the groove at the center of the correction ring 54; when there is offset, the positioning plate 51 contacts the correction plate 56 at one end of the correction ring 54 and presses the correction ring 54 to rotate; under the action of the reset spring 57, the correction ring 54 is driven to rotate in the opposite direction and reset, so that the positioning plate 51 returns to the center groove of the correction ring 51; the use of two sets of positioning plates 51 and positioning grooves 52 arranged symmetrically can adapt to different offset directions of the adsorption plate 31.

[0119] Through the above-mentioned structural design, when the adsorption plate 31 adsorbs the brush plate 32, the brush plate 32 is brought into contact with the correcting ring 54, and under the action of the reset spring 57, the offset positioning plate 51 is corrected and positioned, so that the brush plate 32 is aligned with the center of the adsorption plate 31, and then the brush plate 32 is aligned with the center of the spray plate 10, thereby ensuring comprehensive cleaning of the spray plate 10; at the same time, under the action of the adsorption force of the adsorption plate 31, the brush plate 32 will not fall off during the correction process of the positioning plate 51 by the reset spring 57.
