Description

[Detailed explanation of the invention] For example, brushing the epidermis of cows not only improves meat quality in beef cows and increases milk yield in dairy cows, but also removes dirt from the hair and dandruff from the skin. It also has excellent benefits, such as improving the health of cows by stimulating the skin.

The present invention relates to a brush device for electrically brushing livestock animals, and in particular, the brush body thereof is improved.

Examples thereof will be described below with reference to the accompanying drawings.

In the figure, this brush device consists of a main body 1 and a brush body 3 that is driven by the main body 1 and is surrounded by a brush cover 2 approximately half its circumference.

First, the main body 1 has a motor 4 provided in a cylindrical housing 5, and the shaft of the motor 4 is connected to a drive shaft 6 that projects forward of the main body 1 via a speed reducer 7. 8 is a motor support made of an elastic material;
9 is a cooling fan for the motor 4, 10 is an operation control switch for the motor 4, and 11 is a current breaker. The housing 5 has a plurality of intake ports 12 on the rear end surface and an exhaust port 13 on the front end surface, and furthermore, a grip portion 14 with a smoothly narrowed diameter is formed at the front. Reference numeral 15 denotes a bearing tube that surrounds the outer periphery of the drive shaft 6 that protrudes from the main body 1 and has its base end fixed to the frame of the motor 4, etc.;
Bearings 16 and 17 for supporting the drive shaft 6 are mounted at the tip and inside of the shaft. 18 is a knob for operating the switch 10, and a flange 19
has. This flange 19 has a previous intake port 12.
A plurality of openings 20 are formed corresponding to the openings 20, and when the motor is stopped, these openings 20 and the intake port 12
do not match, the intake port 12 is closed, and when the switch 10 is operated via the operating knob 18 to rotate the motor 4, both ports 12 and 20 match, and the intake passage is opened. It's getting old.
21 is a filter placed over the opening 20, and 22 is a power cord.

The brush body 3 is obtained by planting brush bristles 24 on the outer periphery of a cylindrical base body 23 made of synthetic resin, and has a relatively large diameter for fitting the bearing tube 15 from the rear end surface of the base body 23. Furthermore, a through hole 26 for the drive shaft 6 and a plurality of holes 27, which are open to the distal end surface of the base body 23, are formed at the center of the rear end and at the outer periphery of the center. Reference numeral 28 denotes a plurality of radial locking grooves formed in the axial direction of the hole wall of the fitting hole 25. That is, in the brush body 3, the base body 23 is removably inserted into the bearing cylinder 15 and the drive shaft 6 through the fitting hole 25 and the through hole 27,
Furthermore, rotation can be prevented by engaging the pin 29 of the drive shaft 6 with the locking groove 28.

Furthermore, the brush cover 2 that surrounds approximately half the circumference of the brush body 3 has a shaft hole 31 in its front end wall 30 that fits into the tip of the drive shaft 6, and a rear end of the brush cover 2 that surrounds approximately half of the circumference of the brush body 3. is fixed.

In the above configuration, when the motor 4 is energized now, its rotation is transmitted to the drive shaft 6 via the reducer 7.
It is further transmitted to the brush body 3. Therefore, the operator can brush the cow by holding the grip part 14 of the main body 1.

By the way, in the brush body 3, its base body 23
Since a hole 27 is formed separately from the through hole 26 of the drive shaft 6, when installing the brush body 3, the hole 27 is formed separately from the through hole 26 of the drive shaft 6.
The through hole 26 can be inserted into the drive shaft 6 while viewing the drive shaft 6 through the drive shaft 7. Therefore, the brush body 3 can be quickly attached without much effort.

As described above, the present invention has a main body that has a built-in motor and a drive shaft linked to the motor that protrudes outward, and brush bristles planted on the outer periphery of the base body, which are rotated by the drive shaft. The brush body is provided with a plurality of holes in the axial direction of the base body in addition to the through-hole of the drive shaft, so that the axis of the drive shaft relative to the brush body is provided through the holes. This makes it easier to attach the brush body. In addition, when the base is made of synthetic resin, the holes serve to dissipate heat during molding, shorten the shot cycle, and also prevent sinks and nests in the area where the brush bristles are installed. It is played.
