Description

TECHNICAL FIELD

The present disclosure relates to the technical field of car washing machines, and in particular, to a swinging spray device with a novel structure.

DESCRIPTION OF RELATED ART

A standard configuration on an existing car washing machine is a swinging spray device, which is usually supported by a spray frame composed of a spray beam and columns. Nozzles and a mechanism for driving the nozzles are mounted on the spray frame, and each swing shaft is fixed at two ends by vertical belt bearing seats. The vertical belt bearing seats are excessive, need to be accurately mounted to ensure correct operation, and are prone to wear under a lot of axial load and susceptible to damage by vibration. As a result, the car washing machine is prone to malfunctions and requires frequent maintenance.

Therefore, a significantly simplified swinging spray device without vertical belt bearing seats is urgently needed to solve the problems existing in the prior art.

SUMMARY OF THE PRESENT DISCLOSURE

An objective of the present disclosure is to provide a swinging spray device with a novel structure in response to the above problems existing in the prior art.

In order to achieve the above objective, the present disclosure employs the following technical solution: A swinging spray device with a novel structure includes:

• • nozzles for swinging spray washing on a top and two sides of a vehicle;
  • a reduction motor, mounted on a car washing machine and used for driving each nozzle to swing;
  • a short connecting rod with one end in driving connection with the reduction motor through a rotating arm and the other end rotatably connected to a cross connecting rod and an upper swing arm respectively, where the other end of the upper swing arm is connected to the nozzle, and the upper swing arm is mounted on the car washing machine through a swing assembly;
  • the cross connecting rod with one end rotatably connected to the short connecting rod and the upper swing arm simultaneously and the other end connected to a top end of a vertical connecting rod through a middle swing arm, where the middle swing arm is mounted on the car washing machine through a swing assembly; and
  • the vertical connecting rod with a bottom end connected to the nozzle through a lower swing arm, where the lower swing arm is mounted on the car washing machine through a swing assembly.

Working principle and beneficial effects are as follows: 1. Compared with the prior art, the present disclosure employs the swing assembly to mount each middle swing arm and upper swing arm, and neither large spray brackets nor vertical bearing seats are required to mount the nozzles and each swing arm, thereby simplifying the structure, reducing costs, reducing malfunctions to a certain extent in the absence of vertical bearing seats, and making the device more stable and reliable; and

• • 2. The present disclosure employs the reduction motor to drive each nozzle to swing, so that the spraying effect is more uniform; and a linkage mechanism among the short connecting rod, the cross connecting rod, and the vertical connecting rod ensures that the swinging is more stable, the spraying is more accurate, the entire structure is simple and easy to operate, and maintenance and replacement are facilitated.

Further, the nozzles include a first nozzle located in a middle position of a top of the swinging spray device and second nozzles located on two sides of a bottom of the swinging spray device, and the two second nozzles are symmetrically arranged. The present disclosure can implement the swinging spray washing on the top and two sides of the vehicle to effectively improve car washing efficiency.

Further, the first nozzle is connected to the upper swing arm through a top swing pipe, and the top swing pipe is rotatably connected to the swing assembly.

Further, the second nozzle is connected to the lower swing arm through a side swing pipe, and the side swing pipe is rotatably connected to the swing assembly.

Further, both the top swing pipe and the side swing pipe are connected to a high-pressure water pipe through rotary joints to supply water to the nozzles. Water can be supplied without affecting rotation of the swing pipes.

Further, the rotating arm is rotatably connected to the short connecting rod through a fisheye joint, and the other end of the short connecting rod is also rotatably connected to the upper swing arm through a fisheye joint. The fisheye joint, also known as a rod end joint bearing, has the advantages of simple bearing installation, compact structure, high load capacity, good friction resistance, good sealing performance, convenient maintenance, and the like, and can easily connect the rotating arm and the short connecting rod, as well as the short connecting rod and the upper swing arm.

Further, one end of the cross connecting rod is rotatably connected to the upper swing arm through a fisheye joint, and the other end is also rotatably connected to the middle swing arm through a fisheye joint. The upper swing arm and the cross connecting rod, as well as the cross connecting rod and the middle swing arm can be easily connected.

Further, the top end of the vertical connecting rod is rotatably connected to the middle swing arm through a fisheye joint, and a bottom end is also rotatably connected to the lower swing arm through a fisheye joint. The vertical connecting rod and the middle swing arm, as well as the middle swing arm and the lower swing arm can be easily connected.

Further, both the reduction motor and the swing assembly are fixed on the car washing machine through connectors. The installation is convenient.

Further, each swing assembly is provided with at least one mounting flange surface, which is fixed on the car washing machine through a connector. The installation is convenient.
