High-low-pressure hybrid watering cart

Abstract

The invention relates to the field of pavement cleaning, in particular to a high-low-pressure hybrid watering cart which comprises a cart body and a water tank mounted on the cart body. The cart body is further provided with a high-pressure cleaning mechanism which comprises a plunger pump and a power unit supplying power to the plunger pump. A pipeline is detachably connected between the plunger pump and the water tank, and the plunger pump is connected with a water gun. By implementing the scheme, the purposes of high-pressure flushing, low cost and water and energy conservation can be achieved conveniently.

Description

technical field [0001] The invention relates to the field of road surface cleaning, in particular to a high-low pressure mixed sprinkler. Background technique [0002] At present, two types of equipment are generally used for the cleaning of roads, squares, sidewalks and other road surfaces. One is the traditional sprinkler, which is usually equipped with a water tank on the car body as a water source, and uses the chassis engine , power take-off, and transmission shaft drive the water pump to complete front spraying, side spraying, watering and other actions. The disadvantage of this type of sprinkler is that because the power of the watering action is taken from the engine of the chassis of the car body, during the watering process the car The body needs to be in the running state all the time, so the average daily fuel consumption is 55-60L, resulting in a lot of waste of fuel. In addition, it is necessary to invest 4 drivers and cleaning workers in the work process, and ...

[0002] At present, two types of equipment are generally used for the cleaning of roads, squares, sidewalks and other road surfaces. One is the traditional sprinkler, which is usually equipped with a water tank on the car body as a water source, and uses the chassis engine , power take-off, and transmission shaft drive the water pump to complete front spraying, side spraying, watering and other actions. The disadvantage of this type of sprinkler is that because the power of the watering action is taken from the engine of the chassis of the car body, during the watering process the car The body needs to be in the running state all the time, so the average daily fuel consumption is 55-60L, resulting in a lot of waste of fuel. In addition, it is necessary to invest 4 drivers and cleaning workers in the work process, and because the water pressure of the traditional sprinkler is small, In order to ensure the cleaning strength, the flow rate of the sprinkler needs to be increased, resulting in the water volume of 10 tons per tank being used up in 1.5 hours on average, and 4 times of water adding operations are required every day, and each time adding water takes 0.5 hours, thus greatly shortening the road surface cleaning time and causing Waste of a lot of water resources; the other is the high-pressure cleaning vehicle, because it requires a unified design of the vehicle body, water tank, power, etc. to cooperate with the high-pressure cleaning effect, so the overall design and assembly can only be carried out in professional institutions forming

At the same time, a set of engine unit, power take-off, pneumatic clutch (or electromagnetic clutch) is added to the original car chassis, and the high-pressure water pump is driven through the coupling, but the cost of such equipment is high, and the unit price of each unit is as high as more than 500,000
