Description

Technical Field

[0001] The utility model relates to the technical field of road cleaning, in particular to an auxiliary blowing cleaning device for a road cleaning vehicle. Background Art

[0002] Road sweeper is a kind of efficient, environmentally friendly and safe road cleaning equipment, which is widely used in various road cleaning and maintenance work.

[0003] When the existing road sweepers are performing cleaning tasks, technicians have found that fine particles such as sand and pebbles often accumulate on the edge of the road or roadbed, which cannot be cleaned up in one go. Since it is impossible to clean up in one go, the sweepers have to perform repeated cleaning operations, which not only seriously affects work efficiency, but also leads to a significant increase in operating costs. What is more worrying is that in the repeated reversing cleaning process, there are road safety hazards that cannot be ignored, which pose a potential threat to traffic safety. Utility Model Content

[0004] The main purpose of the utility model is to provide an auxiliary blowing and cleaning device for a road sweeper, so as to solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An auxiliary blowing and cleaning device for a road sweeper comprises a sweeper body, and cleaning brushes are arranged on both sides of the sweeper body. A blowing and cleaning assembly is installed on the sweeper body, and the blowing and cleaning assembly comprises a blowing system and a spraying system. The blowing system comprises an induced draft fan and an air blowing duct, the air blowing duct is connected to the induced draft fan, a narrowing section is arranged at the end of the air blowing duct, and a strip-shaped air outlet is arranged at the end of the narrowing section. The spraying system comprises a water tank, a connecting pipe, a nozzle pipe and a nozzle which are connected in sequence, the nozzle pipe is located on the upper side of the narrowing section and is parallel to the narrowing section, and a plurality of nozzles for spraying water toward the side of the sweeper body are arranged at equal intervals on the nozzle pipe.

[0007] Furthermore, a water pump is provided on the connecting pipe.

[0008] Furthermore, the number of the nozzles is 5, and the nozzles are arranged between the cleaning brush and the rear wheel of the cleaning vehicle body.

[0009] Furthermore, the connecting pipe is connected to one end of the nozzle pipe, and the angle between the connecting pipe and the nozzle pipe is a right angle.

[0010] Furthermore, a sealing head is provided at one end of the nozzle pipe away from the connecting pipe.

[0011] Further, the blowing duct is constructed in an L shape.

[0012] The utility model also includes other components that enable the auxiliary air blowing and sweeping device for road sweeping vehicles to be used normally, and these devices or components all adopt conventional technical means in the field. In addition, the devices and components not limited in the utility model all adopt conventional technical means in the field, such as the induced draft fan in this application. In the specific implementation process, the appropriate device or component model can be selected according to the specific working scene.

[0013] The working principle of the utility model is as follows: when the road sweeper is cleaning, the induced draft fan is started, the impeller of the induced draft fan rotates at high speed and generates high-speed airflow, the high-speed airflow flows into the blowing duct, the cross section of the narrowed section shrinks sharply, and the air volume of the air outlet increases several times, which can instantly blow sand, pebbles and other debris on the road to the bottom of the roadbed, so as to achieve the purpose of cleaning the road surface in one go. In addition, in order to avoid dust when the blowing system cleans up debris, which affects driving safety, the spray system and the blowing system work synchronously, which greatly reduces the generation of dust and ensures driving safety.

[0014] Compared with the prior art, the utility model has the following beneficial effects: 1. The road cleaning efficiency is high, and the cleaning can be completed in one go, which reduces the operating cost and ensures the safety of driving operations. 2. The renovation and maintenance cost is low, and the operation is convenient and easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS
