Then rely on the internal gas pressure difference of the jar body 3.1 that forms under the effect of self priming pump 3.11, absorb mud, this process can be dismantled scraper means 6 and directly absorb mud through sewage suction pipe 9 or do not dismantle scraper means 6 and absorb through scraper means 6 and sewage suction pipe 9. The sewage, sludge and other pollutants are sucked, and the sewage sucking work is finished.
When the object of cleaning is the biogas digester, after the dirt absorbing work is finished, the high-heat and perishable organic matters originally contained in the tank body 4.2 can be pushed by the tank body lifting hydraulic cylinder 4.1 to dump towards the biogas digester. If the sludge in the tank 3.1 is too much, the sludge can be dumped into the emptied tank 4.2. In addition, considering that the operator may be infected with bacteria, viruses, etc. in the filth, the upper part is cleaned by a water gun 8 provided at the tail of the vehicle. The country generally lacks disinfection facilities, and for this reason, this soil pick-up car installs side disinfection atomizer 7. The supporting tube telescopic hydraulic cylinder 7.3 is extended to push the third section of nozzle supporting tube 7.5 to horizontally incline, the first section of nozzle supporting tube 7.2 and the second section of nozzle supporting tube 7.4 are sequentially extended under the power of the built-in hydraulic cylinder, and when the supporting tube is completely unfolded, the disinfectant transported through the disinfectant outlet 2.5 is sprayed through the nozzle 7.6.
The utility model discloses the nothing is mentioned the part and is applicable to prior art.
