The end face of the third bevel gear 16, which is close to one end of the fixed ring 12, is fixedly connected with a second friction ring 17. When the fixed ring 12 abuts against the third bevel gear 16, the second friction ring 17 increases the friction force between the fixed ring 12 and the third bevel gear 16, and the friction force between the fixed ring 12 and the third bevel gear 16 is large enough to enable the fixed ring 12 to drive the third bevel gear 16 to rotate.
It should be noted that, the rotation damping between the first bevel gear 13, the second bevel gear 15, the third bevel gear 16 and the fixed column 5 is smaller, and the rotation resistance of the first bevel gear 13, the second bevel gear 15, and the third bevel gear 16 is smaller, so that the fixed ring 12 can smoothly drive the first bevel gear 13 or the third bevel gear 16 to rotate.

A plurality of second blades 21 are rotatably arranged in the grooves, the second blades 21 are fixedly connected with the first blades 19 through annular plates 20, and the annular plates 20 are in rotary fit with the fixed columns 5.
Specifically, the fixed column 5 is provided with a second rotating hole, the annular plate 20 is rotatably arranged in the second rotating hole, the annular plate 20 is in sealing contact with the fixed column 5, the outer circumferential surface of the annular plate 20 is fixedly connected with the second blades 21, and the inner circumferential surface of the annular plate 20 is fixedly connected with the first blades 19.
The through hole 31 is formed in the inner wall of one end of the water tank 22, which is close to the connecting block 4, and the through hole 31 is internally provided with the one-way valve 32, and the one-way valve 32 can enable outside air to enter the water tank 22.
Working principle: the apparatus is mounted to the vehicle body by means of hydraulic cylinders 1, and is transported to a suitable location by means of the vehicle body. Initially, the split bar 33 is directly above the punch mechanism, with the split bar 33 facing up and the punch mechanism facing down. Under the action of the first spring 9, the drill rod 10 is located in the lower part of the mounting block 7, and the fixing ring 12 abuts against the second friction ring 17. The water level in the water tank 22 is lower than the height of the second vane 21.
When breaking rock, firstly, drilling holes in the rock.
When punching, the hydraulic cylinder 1 and the second motor 6 are started, and the second motor 6 is rotated clockwise.
The hydraulic cylinder 1 is extended, the fixing frame 2 moves downwards, and the punching mechanism moves downwards. The dust cover 24 is abutted against the rock, and the lower end face of the dust cover 24 is abutted against the rock. The drill rod 10 then continues to move downwardly and the dust cap 24 slides along the drill rod 10, the extension rod 23 contracts and the second spring 26 is compressed. When the drill bit 11 is in contact with rock, as the fixed column 5 moves downward, the drill rod 10 moves upward relative to the fixed column 5, and the upper end of the drill rod 10 enters the mounting block 7 and compresses the first spring 9. The fixed ring 12 moves upward relative to the first bevel gear 13 until the fixed ring 12 abuts against the first friction ring 14. The drill bit 11 performs a hole in the rock by means of the hydraulic cylinder 1 and the second motor 6.
Meanwhile, as the friction force between the fixed ring 12 and the first friction ring 14 is large enough, the fixed ring 12 drives the first bevel gear 13 to rotate clockwise through the first friction ring 14, the first bevel gear 13 drives the third bevel gear 16 to rotate anticlockwise through the second bevel gear 15, the third bevel gear 16 drives the first blade 19 to rotate anticlockwise, an upward suction force is generated in the installation cavity 18, and air and dust and debris in the dust cover 24 are sucked into the installation cavity 18 through the first hose 27 and enter the collection box through the connecting pipe 29.
Simultaneously, the first blades 19 drive the annular plate 20 and the second blades 21 to rotate anticlockwise, suction force is generated in the water tank 22, external air enters the water tank 22 through the through holes 31 and the one-way valves 32, and the air in the water tank 22 enters the dust cover 24 through the second hoses 30, so that air is supplemented in the dust cover 24, and the dust cover 24 is prevented from deforming.
After the completion of the drilling, the hydraulic cylinder 1 is shortened and the second motor 6 is rotated counterclockwise, so that the drill bit 11 gradually withdraws from the inside of the drilled hole. During the drill withdrawal process, the drill bit 11 is no longer blocked by rock, the drill rod 10 moves downwards relative to the fixed column 5 under the action of the first spring 9, the fixed ring 12 is separated from the first friction ring 14 until the fixed ring 12 abuts against the second friction ring 17, and the friction force between the fixed ring 12 and the second friction ring 17 makes the fixed ring 12 drive the second friction ring 17 to rotate anticlockwise. The first vane 19 in turn rotates counter-clockwise creating an upward suction within the mounting cavity 18 drawing air and debris dust within the dust cap 24 into the mounting cavity 18 and into the collection bin through the connecting tube 29. So that the dust and dust generated during the gradual withdrawal of the drill bit 11 from the borehole is also sucked into the collection bin. Simultaneously, the second blade 21 rotates anticlockwise, so that outside air enters the water tank 22 through the through hole 31 and the one-way valve 32, and air in the water tank 22 enters the dust cover 24 through the second hose 30, and air in the dust cover 24 is supplemented.
After the drill is removed, the first motor 3 is started, the connecting block 4 is rotated 180 degrees, the splitting rod 33 faces downwards and is opposite to the drill hole, and the punching mechanism is inverted and is located above the splitting rod 33. The hydraulic cylinder 1 is then activated to bring the split rod 33 down into the borehole. Then a hydraulic system matched with the splitting rod 33 is started to split and crush the rock.
After the punching mechanism is inverted, the drill bit 11 is contacted with the outside, and the drill bit 11 is cooled. Because of the large amount of heat generated by bit 11 during the drilling process, the temperature of bit 11 is relatively high. At this time, the temperature of the drill bit 11 is rapidly lowered.
After the punching mechanism is inverted, water enters the groove, and the second blade 21 is positioned in the water tank 22.
The second motor 6 is started to rotate the drill rod 10 and the drill bit 11 anticlockwise, and the fixed ring 12 drives the second blades 21 to rotate anticlockwise through the third bevel gear 16. The second blade 21 delivers the water in the water tank 22 into the second hose 30 and then sprays the water onto the drill bit 11, thereby rapidly cooling the drill bit 11. And at the same time, the outside air enters the water tank 22 through the one-way valve 32, so that the air pressure inside and outside the water tank 22 is balanced.
The first vane 19 rotates anticlockwise causing water in the dust cap 24 to enter the mounting chamber 18 via the first hose 27 and then into the collection tank via the second hose 30.
After the temperature reduction is completed and the splitting work of the splitting rod 33 is completed, the fixing frame 2 is moved upwards by the hydraulic cylinder 1, so that the splitting rod 33 is withdrawn from the drilled hole.
The first motor 3 is started to rotate the connecting block 4 by 180 degrees, the splitting rod 33 is upwards, and the punching mechanism is downwards so as to perform the next work.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
