Description

Description: FIELD OF THE INVENTION The present invention relates to a brush device installed in a car wash machine installed in a gas station and used for washing a car.

2. Description of the Related Art A conventional brush device has, for example, a structure shown in FIG. That is, a vertical through hole 51 is formed at the free end of the swingable arm 50, and the vertical drive shaft 52 inserted through the through hole 51 is attached to the upper surface and the lower surface of the arm 50 by a bolt and nut 5.
An output shaft 59 and a drive shaft 52 of a motor (rotary driving device) 58 rotatably supported by bearings 55 and 56 mounted via 3, 54 and mounted on the arm 50 via bolts and nuts 57.
And are linked together via an endless transmission device 60 provided in the arm 50. The core 61 is externally fitted and fixed to the lower end of the drive shaft 52, and the brush shaft 62 is externally fitted and fixed to the core 61. Furthermore, a waterproof protective cover 63 is provided on the upper end of the drive shaft 52.
Is installed. The endless transmission device 60 includes a drive chain wheel 64 fixed to the output shaft 59 and a passive chain wheel 65 fixed to the drive shaft 52.
And a chain 66 hung between both chain wheels 64 and 65. 67 is a brush bristle and 68 is a cover.

According to this conventional type, by rotating the drive shaft 52 via the endless transmission device 60 by driving the motor 58, the brush shaft
62 and brush bristles 67 can be rotated together to perform the desired car wash.
The waterproof protective cover 63 prevents the spray water splashing at that time from entering the bearing 55.

Problems to be Solved by the Invention According to the above conventional method, a structure and an operation for attaching the waterproof protective cover 63 are required. Also a pair of bearings
Since 55 and 56 must be arranged separately in the upper and lower parts, it is difficult to form a unit because of the structure. Further, a part of the spray water penetrates from below the waterproof protection cover 63, and this enters the bearing 55 and cannot completely discharge water.

An object of the present invention is to provide a brush device for a car wash machine, which can be simplified in structure and mounting, can be assembled and unitized, and can be sufficiently waterproofed.

Means for Solving the Problems In order to achieve the above-mentioned object, a brush device for a car wash according to the present invention has a cylindrical body attached to an arm, the inner end of which is fixed to the inside of the arm, and a drive shaft attached to the cylindrical body. Is rotatably inserted through a bearing, and an inner end of the drive shaft and a rotary drive device provided in the arm are interlocked and coupled through a transmission device provided in the arm, and an outer end of the drive shaft is provided. A core composed of a double cylinder portion and a flange portion is externally fitted and fixed, and a water drain hole is formed in the flange portion, and a brush shaft is externally fitted and fixed to the core.

According to the configuration of the present invention, the cylindrical body, the bearing, and the drive shaft can be unitized, and the inner end of the cylindrical body can be positioned inside the arm to be fixed to the arm. After the core is externally fitted and fixed to the end, the brush shaft is externally fitted and fixed to the core to perform the assembly. The spray water scattered during car wash does not enter the bearing side because the drive shaft and the inner end of the cylinder are located inside the arm, and the water that entered the double cylinder of the core is a drain hole. Can be removed through.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 2, a gate-shaped car wash main body 1 has a plurality of wheels 2
It is mounted on the rail 3 via the carriage and can be reciprocally traveled on a fixed route by the operation of a travel drive device (not shown). The car wash machine body 1 has a finishing wax arch 4
A base wax arch 5, a rinse arch 6, a detergent arch 7, a top nozzle 8 and a high pressure spray nozzle 9.
A side nozzle 10, a side brush 11, a top brush 12, a rocker brush 13, and a vehicle height detection device 14 are incorporated. 15 indicates a car. The rocker brush
13 is a pair (left and right pair) in the width direction, and is shown in FIG.
As shown in the figure, they are attached via swingable arms 20, respectively, and can be moved toward and away from each other via a swing drive device (not shown). An assembling lower plate 20A of the arm 20 is formed with a vertical through hole 21 at a free end thereof, and a flange portion 22A of a cylindrical body 22 inserted into the through hole 21 from above is engaged with the lower plate 20A. By fixing with bolts 23, the cylindrical body 22 is fixed with its inner end (upper end) positioned inside the arm 20. A drive shaft 26 is rotatably inserted into the cylindrical body 22 via a pair of bearings 24 and 25, and is a motor (rotary drive device) mounted on the upper portion of the arm 20 via a bolt 27.
The output shaft 29 of 28 and the drive shaft 26 are interlockingly connected via a transmission device 30 provided in the arm 20. This transmission
30 is an endless type drive chain wheel 31 fixed to the output shaft 29
And a chain 33 fixed to the drive shaft 26, and a chain 33 hung between the chain wheels 31 and 32. At the outer end (lower end) of the drive shaft 26, an outer cylinder portion 34A, an inner cylinder portion 34B, and a flange portion 34
A core 34 made of C is fitted on the inner cylindrical portion 34B of the core 34 and is fixed via a key or a bolt 35.
A brush shaft 36 is externally fitted to and fixed by a bolt 37.
A water drain hole 38 is formed in the flange portion 34C. 40
Indicates a brush bristle, and 41 indicates a cover.

In the above embodiment, the cylindrical body 22, the bearings 24 and 25, the drive shaft 26, and the passive chain wheel 32 are unitized, and fitted into the lower plate 20A before assembly from above through the through holes 21. After that, the lower plate 20A and the flange portion 22A are fixed by the bolts 23 to be assembled. Next, after the core 34 is externally fitted to the outer end of the drive shaft 26 and fixed with the bolts 35, etc., the brush shaft 36 is externally fitted to the core 34 and fixed with the bolts 37, whereby the whole assembly can be performed.

When using, the desired car wash can be performed by stopping the car 15 and making the car wash machine travel back and forth. At that time, the side brush 11 rotates the drive shaft 26 via the transmission device 30 by the start of the motor 28, integrally rotates the brush shaft 36 and the brush bristles 40, and moves toward and away from the automobile 15 via the arm 20. Car wash as expected Further, the sprayed water that has scattered does not enter the bearing 24 side at all because the inner ends of the drive shaft 26 and the cylindrical body 22 are located inside the arm 20, and
The portion falling from the outside of 22 is received by the flange portion 34C and falls through the water draining hole 38.

In the above embodiment, the rocker brush 13 is shown as the brush device, but this is not limited to the side brush 11 and the top brush 12.
And so on.

Effect of the Invention According to the present invention having the above-described configuration, the inner end of the tubular body can be positioned in the arm and fixed to the arm in a state where the tubular body, the bearing, and the drive shaft are unitized. Assembly can be performed by externally fitting and fixing the core to the outer end of the shaft, and then externally fitting and fixing the brush shaft to the core.
This simplifies the structure and mounting, and makes it an assembly unit. In addition, spray water scattered during car washing does not enter the bearing side because the drive shaft and the inner end of the cylinder are located inside the arm, and it is possible to perform sufficient waterproofing.
Furthermore, the water that has entered the double cylinder portion of the core can be removed at any time through the water drain hole.
