Description

Technical Field

[0001] This utility model relates to the field of roadbed construction mixture paving technology, and more specifically, it relates to a watering device for mixture paving. Background Technology

[0002] Before paving the asphalt mixture, the working surface needs to be cleaned, such as by washing with water. If the underlying layer has already been compacted by vehicles, a tack coat needs to be applied before paving. Watering operations generally use large truck-mounted water trucks. However, large truck-mounted water trucks have poor maneuverability, and their movement speed along the roadbed is often greater than the asphalt paving speed. Reducing the speed of the water truck to a certain extent increases energy consumption. Therefore, a small-sized, low-energy watering device is needed. Utility Model Content

Then, the steering mechanism 4 is used to control the swing amplitude of the water spraying mechanism 3 for better washing of the working surface before paving the mixture.

[0023] according to Figure 1-4 As shown, the steering mechanism 4 includes a housing 41 and a bracket 42, a movable beam 43, a motor 44, and a transmission assembly 45 installed in the housing 41. The bracket 42 includes a front support 421 and a rear support 422. The top of the front support 421 and the rear support 422 are both provided with U-shaped grooves for the movable beam 43 to slide within them.

A gear rack is provided at the bottom of the movable beam 43, and the transmission gear meshes with the gear rack. The transmission assembly 45 includes a main transmission group and a driven transmission group, which are spaced apart along the length of the movable beam 43. The main transmission group includes a rotatable vertical shaft and a gear fixedly connected coaxially to the column. The gear meshes with a row of teeth provided on the side wall of the movable beam 43. The row of teeth extends along the length of the movable beam 43. There are two gears, which are spaced apart vertically. Between the two gears, there are also two spaced driven bevel gears. A driving bevel gear meshes between the two driven bevel gears. The driving bevel gear is fixedly connected coaxially to the output shaft of the motor 44. The driven transmission group only includes the vertical shaft and a single gear from the main transmission group.

The first section is connected to a water pump, the second section is connected to a variable frequency water pump 6, and the third section is connected to the collection pipe 31. When water flows through the first and second sections, it fills the tank 2 with water, facilitating a short-term water supply to the collection pipe 31 when the external water source is insufficient. When water flows through the first and third sections, it sprays directly from the nozzles 32 to wash the ground. The bypass inlet 312 on the collection pipe 31 is always closed and is used to connect a separate water pipe or oil pipe in specific situations.
