In this embodiment: the machine body 1 is moved to the position where the expansion joint needs to be cut, the rotating turntable 38 drives the driving belt 39 to enable the worm 37 to rotate, the worm 37 drives the worm wheel 36 and the threaded rod 25 to rotate, so that the height of the lifting block 21 is adjusted, the lifting block 21 drives the top block 27 and the bottom plate 28 to lift and adjust together, the top block 27 drives the graduated scale 32 to move downwards, the depth of the needed cutting can be preset and adjusted by observing the graduated scale 32 and the graduation change of the upper side edge position of the mounting frame 19, at the moment, the downwards movement of the top block 27 drives the first spring 29 to push the driving block 22 to move downwards, the driving rod 24 is pushed by the driving groove 23, the arc block 18 slides downwards in the arc groove 17, and as the circle center of the arc groove 17 is the same as the circle center of the driving shaft 12, thereby guaranteed to mesh with first gear 13 all the time when second gear 15 is adjusted, arc piece 18 drives second gear 15 and connecting axle 14 and moves down along arc groove 17 can make cutting dish 5 and regulating plate 33 and dust cover 9 move down together, control lever 34 on the dust cover 9 can receive the spacing of carriage 35, thereby guarantee to be in the state of following cutting dish 5 steady lift together all the time, can not produce the slope, because cutting direction of cutting dish 5 is anticlockwise rotation generally, throw away the dust backward, the region that the cutting knife is close to second pipeline 42 one side that this moment control lever 34 can be better shelters from, avoid the dust to enter into the stable operation of equipment of position influence between first gear 13 and the second gear 15.
Notably, are: when the bottom of cutting knife is contradicted with ground, the cutting knife can be difficult to continue to move down this moment, the continuation of kicking block 27 moves down can make first spring 29 compress gradually, until kicking block 27 moves down and starts driving motor 3 behind the preset position, drive cutting dish 5 rotates the cutting road surface, cutting dish 5 receives the promotion of first spring 29 and moves down gradually when cutting, when the control button 30 that moves down to the bottom plate 28 upside is contradicted to driving block 22, at this moment driving block 22 receives the promotion of bottom plate 28 and no longer moves down, control button 30 triggers simultaneously and makes driving wheel 2 rotate certain angle, the organism 1 moves forward simultaneously cutting dish 5 receives the promotion of road surface again and can slightly move up a section distance, along with the continuation cutting of cutting dish 5, can stop moving down once more after cutting dish 5 reaches the preset height again, so reciprocating has realized the purpose that does not influence driving motor 3 steady state when cutting depth is preset, wherein the elasticity of first spring 29 is great, and be in compression promotion state when driving block 22 and bottom plate 28 are in the same, it can stop the effect of the promotion of the bottom plate 22 can be more high-efficient when setting up and stopping the cutting effect of cutting dish 29 to cut gradually when setting up and stopping the high-speed setting up and cutting effect.
When the driving motor 3 drives the driving shaft 12 to rotate, the rotating column 45 can be made to rotate, the upper side edge of the rotating column 45 is attached to the upper side inner wall of the fixed box 44, the rotating column 45 drives the driving plate 46 to rotate, the driving plate 46 receives the thrust of the second spring 47, the top end of the driving plate 46 is always attached to the inner wall of the fixed box 44 and slides, accordingly, the thrust pushed by the input pipe 40 to one side of the output pipe 43 is generated in the area below the fixed box 44, the suction effect can be generated in the input pipe 40, dust in the dust cover 9 is extracted through the first pipeline 41, the dust outside the dust cover 9 is extracted through the second pipeline 42, the dust is discharged into the collecting box 11 through the output pipe 43 to be collected, a filter screen and an air outlet (not shown) are arranged in the collecting box 11, the air is conveniently filtered and then discharged.
Embodiment two: referring to fig. 1-11 for describing the second embodiment, the first embodiment is further described, and the suction piece in the drawing further includes a suction pump 48 fixedly installed on the machine body 1, an input end of the suction pump 48 is connected with the input pipe 40 in a communication manner, and an output end of the suction pump 48 is connected with the output pipe 43 in a communication manner.
In this embodiment: the suction pump 48 replaces the rotating column 45 and the driving plate 46, so that the device has a simpler structure, but has the disadvantage that the suction pump 48 needs to be separately connected with the energy supply, and the suction pump 48 needs to be separately controlled to be started and stopped, and the suction and dust removal process in the first embodiment synchronously operates along with the cutting state of the cutting disc 5.
