Abstract

PROBLEM TO BE SOLVED: To provide a rotary brush capable of brushing every and all parts of a body such as the root of a horn, a head part, a part under a neck, etc., by a cow or a horse by themselves in a good efficiency and in a short period of time. SOLUTION: This rotary brushing device for a cattle, is provided by supporting a rotary brush 1 in horizontal direction at a frame 11 with a cantilever, installing a spring member 17 for recovering the rotary brush in a prescribed direction at a supporting part 12 thereof in order to make the brush elastically swingable on applying an outer force on the rotary brush 1. As the spring member 17, a closely wound coil spring is used and by setting its initial compression force optionally, it is possible that the swing does not occur unless the cow or horse pushes the rotary brush 1 with a force in a certain extent. Under the supporting part 12, a rotary brush in vertical direction can be installed. Since there is no frame around the rotary brush, a part under the chin and a root of a horn can be brushed freely. And it is also possible to avoid the damage of the brush and frame when the cow or horse pushes the rotary brush in a high power or as an impact.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cattle or horse brush device, and more particularly to a device that is installed in a barn or a ranch so that a cow or horse can brush itself.

[0002]

2. Description of the Related Art Cows and horses, even if they have itchiness on their bodies, cannot scratch themselves, causing stress to accumulate and milking cows to produce poor milk. Cows and horses rub their pillars against barns and tree trunks when the body has itching. For this reason, brushes have been fixed on the walls and pillars of the barn so that when a cow or horse rubs his body against it, it can be effectively scratched (brushed). I have.

[0003] In the above-described method in which a cow or a horse reciprocates the body while brushing is fixed, the above-mentioned method cannot increase the relative speed between the body and the brush, and it takes time for brushing. Cows and horses are brushing until they are satisfied, but in a ranch where many cattle are grazing, brushes must be provided in many places if it takes time to brush one cow. Further, with a brush fixed to a wall or the like, it is difficult to brush a place that tends to itch, such as under a neck or a hairline of a corner.

[0004] Therefore, a cylindrical brush rotatably driven by an electric motor is installed in a barn or a ranch. This kind of cylindrical brush is installed vertically or horizontally,
Both ends are rotatably supported, and are rotatably driven by an electric motor via a speed reducer.

[0005]

A conventional rotary brush device of this type, when installed vertically, brushes the bottom of the neck and the hairline of a corner in the same manner as when a fixed brush is attached to a column. Is difficult. On the other hand, when the brush is installed horizontally, the frame for supporting both ends of the brush will be installed in parallel with the brush. If the frame is placed on the lower side, it will not be possible to brush the hairline of the corner or the head. Also, since a cow or a horse rubs the body with a strong force on the brush, a failure such as damage to the brush or an overload of the electric motor is likely to occur.

Accordingly, the present invention is to provide a livestock rotary brush which enables a cow or a horse to efficiently and quickly brush every part of the body such as the base of the horn, the head, the neck, and the side of the body. It is an issue.

[0007]

According to the present invention, a rotating brush 1 arranged in a lateral direction is supported on a frame 11 by a cantilever, and an urging force for restoring the rotating brush in a predetermined direction is applied to a supporting portion 12 thereof. By providing the spring member 17, the above problem is solved by enabling the rotary brush 1 to resiliently swing vertically and horizontally around the support portion when an external force is applied. As the spring member 17, a leaf spring or a spiral spring whose bending directions are orthogonal to each other may be used, but it is convenient to use a close-wound coil spring in which the drive shaft 13 matches the rotation center axis of the rotary brush 1. It is. The tightly wound coil spring 17 thus arranged
Can rotate the rotary brush 1 vertically and horizontally by one spring, and appropriately set the value of the initial compression force (compression force generated when the wires are in close contact with each other). By setting, the holding force of the rotating brush 1 in a predetermined direction can be set to a desired magnitude. That is, the rotating brush 1 can swing around the support portion 12, but the swing can be prevented from occurring unless the horse or cow pushes the rotating brush 1 with some force.

The term “horizontal direction” as used herein generally refers to a horizontal direction, but it is also possible to install the device slightly obliquely in the vertical direction. Since cows and horses are large and small, when the rotating brush 1 having a certain length is installed diagonally, a portion having a height corresponding to the height can be used. Further, a vertical rotating brush 2 can be provided below the support portion 12 of the horizontal rotating brush 1 provided in the above structure, and the head and chin are the horizontal rotating brush 1, and the body side and the like are in the vertical direction. It is also possible to enable brushing with each rotating brush 2.

In the horizontal rotating brush 1 having the above structure, since no frame exists around the rotating brush, the body can be pressed against the brush from any direction, up, down, left and right of the brush. A cow or horse, such as the base of a horn, can freely press a desired part on the rotating brush 1 for brushing. Further, since the rotating brush elastically bends when the cow or horse pushes the rotating brush with a strong force, it is possible to avoid damage to the brush and the frame when the rotating brush is pushed by impact.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in FIGS. 1 to 4 will be described below. The apparatus of FIG. 1 includes a horizontal rotating brush 1 and a vertical rotating brush 2. As shown in FIG. 2, the two rotating brushes 1 and 2 are fixed to a cylindrical brush shaft 3 at a position where an axial fin-shaped holder 4 divides the circumference into eight equal parts. 5
Is attached. The holder 4 includes two opposing plates 6 and 7, between which the base of the comb 5 is inserted, and the plates 6 and 7 are fastened with bolts 8 to clamp the base of the comb 5. , And is fixed to the brush shaft 3.

A cylindrical joint 10 having a spiral round bottom groove 9 as shown in FIG. 3 is fixed to one end of the horizontal rotating brush 1. A horizontal drive shaft 13 is supported by a support portion 12 formed at the upper end of the frame 11, and keys (not shown) are provided at two positions on the outer peripheral surface thereof. A joint 1 having a spiral round bottom groove 14 formed on the outer peripheral surface at the tip of the drive shaft and a key groove 15 formed on the inner peripheral surface.
6 is fixed. The joints 10 and 16 are screwed to both ends of a tightly wound coil spring 17 to which a predetermined initial compressive force is applied, and then connected by spot welding the appropriate portions of the joints 10 and 16 and the tightly wound coil spring 17. .
The drive shaft 13 penetrates the joint 16 on the support portion side with the key fitted in the key groove 15, and is screwed to the tip of a coil spring screwed to the joint 16 to penetrate the brush-side joint 10. When the rotating brush moves up and down, the tip 13a of the extending portion abuts on the inner peripheral surface of the joint 10 to reduce the swing angle of the rotating brush 1 around the tightly wound coil spring 17. Acts as a restricting stopper.

The vertical rotating brush 2 has a both-ends support structure in which the upper end is pivotally supported by the support portion 12 of the frame and the lower end is pivotally supported by the base portion 18. A motor 19 with a speed reducer is mounted on the support portion 12 of the frame with the output shaft facing downward, and a bevel gear 21 mounted on the output shaft and a second bevel gear mounted on the horizontal drive shaft 13. The second bevel gear 22 further meshes with a third bevel gear 24 provided at the upper end of a shaft 23 of the vertical rotating brush. Therefore, by rotating the motor 19, the horizontal rotating brush 1 and the vertical rotating brush 2 rotate simultaneously.

The rotating brush device having the above structure is installed in a barn or a ranch, and the power of the motor 19 is turned on around the time when cows and horses gather, for example, during feeding and milking, and the rotating brushes 1, 2 Is driven to rotate. When a cow or horse has an itchy body, it brushes it by pressing it against the rotating brushes 1, 2. The brush can be brushed under the neck and chin by pressing the body from above the rotary brush 1 in the horizontal direction, and the head and the base of the corner can be brushed by pressing the body from below the rotary brush 1 in the horizontal direction. The body side can be brushed by pressing the body against the rotating brush 2 in the vertical direction. Since the horizontal rotating brush and the vertical rotating brush are rotating at the same time, it is possible to brush the face, head and body side at the same time.
