In practical application, when the lifting oil cylinder extends downwards, the sucker descends along with the sucker lifting arm until the sucker roller is in contact with the ground, and the telescopic control component is not stressed and is not loosened. At the moment, the sucker independently walks on the ground along with the sucker side roller, and the sucker water suction port can always keep the height consistent with the ground, so that the operation function of the sucker is realized safely and stably.
Wherein, the sucking disc passes through the conveying line and extends to the waste water tank on the washing and sweeping vehicle in. The sucking disc is the receiver that absorbs ground rubbish and sewage, and the waste water tank is the accumulator of rubbish and sewage, and rubbish and the waste water that the sucking disc absorbed get into the waste water tank through pipeline and collect.
How to realize rubbish and sewage overcome the action of gravity and upwards transport to the sewage case, specifically: the upper space of the sewage tank is connected with the high-pressure centrifugal fan, the high-pressure centrifugal fan extracts air in the closed sewage tank to form negative pressure when working, and the formed negative pressure is transmitted to the sucking disc through the conveying pipeline, so that garbage and sewage are sucked into the sewage tank by the sucking disc.

The electric push rod is powered by electric energy and can freely stretch out and draw back. Meanwhile, one end of the electric push rod is hinged with the body of the washing and sweeping vehicle, and the other end of the electric push rod is hinged with the anti-collision support. When the electric push rod moves in a telescopic way, the anti-collision support can be driven to rotate around the articulated shaft of the vehicle body, as shown in fig. 3 and 4. The spray rod support can rotate synchronously along with the anti-collision support, so that the spray rod is driven to rotate, and the angle adjustment and the contraction control of the spray rod are realized. Namely, when the electric push rod extends, the anti-collision support rotates around the lifting base, and meanwhile, the spray rod support and the spray rod rotate to enter a non-working state; on the contrary, when the electric push rod is shortened, the relative position is changed, and the spray rod is opened to enter a working state.
Further, the method comprises the following steps: after the electric push rod stretches to the required working position, the electric push rod keeps a fixed state, and at the moment, the position of the anti-collision support connected with the electric push rod also keeps a fixed state. If the spray lance surpasss the automobile body part when receiving the striking of external object, the spray lance is dodged backward, spray lance support of fastening with it also is rotatory dodges backward thereupon simultaneously, nevertheless anticollision support this moment is in the fastening state and can't follow the spray lance support and rotate jointly and dodge, install anticollision spring between spray lance support and anticollision support and can take place deformation thereupon and stretch, when the striking finishes, anticollision spring tension makes spray lance support and spray lance resume to operating condition, thereby realized dodging the purpose of outside striking, ensured simultaneously that this system can not damage because of external force collision.

Meanwhile, when the external force is separated, the spray rod returns to the operation position due to the left and right tension of the anti-collision spring.
Preferably, the spray rod is arranged at the front end of the washing and sweeping vehicle sucker, water sprayed by the spray rod is high-pressure water, the maximum pressure can reach 25MPa, the impact force of the high-pressure water can effectively remove garbage and dirt on the ground, and meanwhile, a large amount of water splash can be generated; wherein the spray rod comprises at least a left spray rod and a right spray rod; the two spray bars are in an inverted splayed shape and wash towards the middle of the vehicle body, and the left spray bar and the right spray bar form a left-right included angle (145-155 degrees) of 150 degrees; the spray lance setting of this angle can effectually drive the splash of automobile body both sides to the automobile body centre, prevents that the splash from scattering to the automobile body outside for the splash on ground, rubbish etc. are all concentrated in the coverage of sucking disc, ensure that the sucking disc can be with its whole absorption. Meanwhile, the sprayed water column is also inclined forwards, an included angle of about 60 degrees is formed between the sprayed water column and the ground, the vehicle runs forwards when working, and the spray rod generates forward inertial impact along with the application of the vehicle.
The spray rod is arranged at the front end of the sucking disc of the washing and sweeping vehicle, when the distance is kept at 25-35 cm under the working state, particularly in the range of about 30cm, high-pressure water can splash on the ground, sewage entering the sucking disc enters the sucking disc after the splash is scattered, the splash is prevented from splashing on the chassis to cause pollution and incomplete absorption, and therefore the spray rod is kept at a certain distance from the sucking disc. Secondly, water has mobility, drives sewage and rubbish to the vehicle body intermediate position after the spray lance, and the water level in centre risees, and the water level can be fast scatter to both sides to break away from the coverage of sucking disc, therefore the time interval of the interval stroke of sucking disc and spray lance should ensure can not let sewage scatter to both sides and provide the condition. In conclusion, the time difference formed by the distance between the spray rod and the suction disc can meet the requirement of water splash removal, and meanwhile, sewage is prevented from being scattered to two sides. The running speed of the vehicle is about 8-10km/h during operation, and the experiment shows that the distance between the spray rod and the suction cup is about 30cm, so that the requirements of the two conditions can be effectively met.
The spray rod provided by the invention is electrically controlled, so that the operation is more convenient and faster, and the structure is simpler and more reliable. Wherein, adopt the inside and outside flexible mode of rotation of horizontal direction for the extension angle of spray lance is bigger, and area coverage is wideer, all possesses the effect of anticollision buffering simultaneously under the any position state of flexible.
