When the invention is used in concrete, the bin 2 is filled with spraying marking materials such as printing ink, paint and the like; when the marking distance on the working surface needs to be marked, the vehicle body 1 is conveyed to the starting position of the marking, in the initial state, the notch 13 on the annular sleeve 12 is opposite to the vertical rod 6, and the lower end of the vertical rod 6 is popped out of the third through hole 21 under the action of the first pressure spring 19; after automobile body 1 carried to the initial point of hitting, promote automobile body 1 and move along the route of hitting, the shaft rotation can drive first friction pulley 15 on it and rotate, first friction pulley 15 drives rather than the rotation of engaged with second friction pulley 16, second friction pulley 16 drives driving pulley 17 and driven pulley 14 and rotates, driven pulley 14 rotates and drives annular cover 12 synchronous revolution, annular cover 12 rotates and can make the curved edge of notch 13 upwards promote montant 6 gradually, until montant 6 contracts in the third through-hole 21 completely, the liquid of piston 8 top gets into in the workbin 2 through liquid hole 5.
In the process that the vertical rod 6 is pushed upwards, when the baffle 7 below is in contact with the piston 8, the piston 8 moves upwards synchronously along with the vertical rod 6, at the moment, the piston 8 seals the first through hole 9, if the piston 8 cannot slide downwards relative to the vertical rod 6 due to friction force between the piston 8 and the vertical rod 6, when the piston 8 moves upwards along with the vertical rod 6 until the upper surface of the piston 8 is in contact with the inner end of the screw 27, the screw 27 can prevent the piston 8 from continuing to move upwards along with the vertical rod 6, the vertical rod 6 continues to move upwards until the lower end is completely retracted into the third blind hole, at the moment, the piston 8 is in contact with the baffle 7 below, and therefore the first through hole 9 is; at the moment, the lower opening of the liquid inlet hole 11 is positioned below the piston 8, and the spraying agent in the feed box 2 flows into the piston cavity 4 below the piston 8 through the liquid inlet hole 11.
When the annular sleeve 12 rotates to the position that the notch 13 is opposite to the vertical rod 6 again along with the walking of the vehicle body 1, the vertical rod 6 loses the blocking effect of the inner wall of the annular sleeve 12, the vertical rod 6 pops downwards under the action of the first pressure spring 19, the straight edge of the notch 13 which drops steeply can enable the vertical rod 6 to lose the blocking effect instantly and pop out, however, the piston 8 is pushed to be in contact with the upper baffle 7 by the reaction force of liquid below the piston and then moves downwards along with the vertical rod 6, the first through hole 9 is opened at the moment, the piston 8 moves downwards to pass through the lower orifice of the liquid inlet hole 11, the lower part of the piston 8 is separated from the feed box 2, the piston 8 moves downwards to extrude the spraying agent below the piston 8, the spraying agent is sprayed out through the first through hole 9 and the second through hole 10; the vehicle body 1 continues to walk, the annular sleeve 12 continues to rotate, the vertical rod 6 is pushed to the uppermost position again, the piston 8 is located above the lower orifice of the liquid inlet hole 11, liquid is fed again below the piston 8, and when the notch 13 is opposite to the vertical rod 6 next time, the vertical rod 6 moves downwards to be sprayed again, and the cycle is repeated.
When the vehicle body 1 moves for a fixed distance, the annular sleeve 12 rotates for a circle, and the device sprays once, so that fixed-distance dotting marking is realized; if the spraying distance is to be adjusted, the transmission ratio between the wheel and the annular sleeve 12 needs to be adjusted; if the distance needs to be reduced, the transmission ratio between the wheels and the annular sleeve 12 needs to be reduced, namely, under the condition that the vehicle speed is not changed, the angular speed of the annular sleeve 12 is increased, and the specific method comprises the following steps: when the spindle 22 of the second friction wheel 16 is kept from rotating and the second friction wheel 16 is rotated to move towards the large end of the first friction wheel 15, the diameter of the first friction wheel 15 at the meshing part with the second friction wheel 16 is increased, and when the rotating speed of the first friction wheel 15 is not changed, namely the vehicle speed is not changed, the rotating speed of the second friction wheel 16 is increased, the rotating speeds of the driving pulley 17 and the driven pulley 14 are increased, namely the rotating speed of the annular sleeve 12 is increased, therefore, the stroke of the vehicle body 1 is reduced within one rotation time of the annular sleeve 12, namely the spraying mark distance is reduced, and the lock nut 23 is tightened after the second friction wheel 16 is adjusted; on the contrary, if the distance needs to be increased, the transmission ratio between the wheels and the annular sleeve 12 needs to be increased, that is, under the condition that the vehicle speed is not changed, the angular speed of the annular sleeve 12 is slowed down, and the specific method comprises the following steps: when the spindle 22 of the second friction wheel 16 is kept to be rotated, the locknut 23 is loosened, the second friction wheel 16 is rotated to move towards the small end of the first friction wheel 15, the diameter of the first friction wheel 15 at the meshing part with the second friction wheel 16 is reduced, and when the rotating speed of the first friction wheel 15 is not changed, namely the vehicle speed is not changed, the rotating speed of the second friction wheel 16 is reduced, the rotating speeds of the driving pulley 17 and the driven pulley 14 are reduced, namely the rotating speed of the annular sleeve 12 is reduced, so that the stroke of the vehicle body 1 is increased within one-circle rotation time of the annular sleeve 12, namely the spraying mark interval is increased, and the locknut 23 is tightened after the second friction wheel 16 is adjusted; the second friction wheel 16 moves axially and simultaneously has displacement in the direction perpendicular to the axis, and the sliding blocks 24 at the two ends of the mandrel 22 slide in the sliding grooves 25 to realize the displacement of the second friction wheel 16 in the direction; graduations may be marked along the spindle 22 of the second friction wheel 16 to facilitate accurate adjustment of the spray spacing; the tensioner 28 ensures that the belt 18 is effectively tensioned.
After the spraying agent in the work bin 2 is used up, the plug of the feeding hole 32 is opened to add the spraying agent, when the spraying agent needs to be replaced, the plug of the discharging hole 33 is opened to empty the work bin 2, and then new spraying agent is added.
When the dust-proof rubber sleeve is not used, the annular sleeve 12 is rotated to the position where the notch 13 is opposite to the vertical rod 6, so that the vertical rod 6 is popped up, the piston 8 separates the material box 2 from the outside and is convenient to use next time, and then the lower end of the vertical rod 6 is sleeved with the dust-proof rubber sleeve.
The fixing block 3 and the components in the fixing block can be integrally replaced when damaged, and the vertical rod 6 and the components on the vertical rod can be independently replaced.
The invention has the following remarkable advantages: firstly, the invention adopts a spraying mode to carry out dotting marking, the vertical rod 6 does not contact and collide with the ground, the damage to parts is avoided, the service life is prolonged, the maintenance cost is reduced, and the spraying marking is more obvious and clear compared with the dotting pen, and the dotting effect is good; in addition, the dotting distance can be rapidly and steplessly adjusted, and the adaptability is strong; moreover, the invention has the advantages of light volume, convenient carrying and use, is equivalent to a toy car, can be pushed along a dotting route, can be adapted to both linear and curved dotting, and has high dotting speed and high efficiency.
