Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a first embodiment of a spray dispensing device for livestock of the present invention, FIG. 2 is a vertical side view of the same, and FIG. 3 is a vertical side view of a main part of the same. The spray nozzle 2 and the supply push button 2 are supply buttons for supplying a spray chemical, and the spray nozzle 1 and the supply push button 2 are arranged side by side in a nozzle case 3 as an attachment.

The supply push button 2 is slidably inserted into a supply pipe 4 connected to a non-illustrated pressure-feeding pipe for the spray liquid, and the tip of a valve stem 5 formed integrally with the supply push button 2 is inserted into the supply pipe 4. The on-off valve 6 is in contact with the on-off valve 6 disposed, and is normally urged by a spring 7 in the direction of the valve rod 5 so as to close the flow path in the supply pipe 4.

The spray pipe 8 is connected in a direction perpendicular to the supply pipe 4 so as to communicate with the flow path in the supply pipe 4.
Open. In this case, the spray nozzles 1 are positioned above the supply push buttons 2 and each is attached to the nozzle case 3.

Then, the supply push button 2 and the spray nozzle 1
The upper portion of a push plate 9 as an operating plate which is pressed by the nose of a livestock and moves to push the supply push button 2 as an operation member of the button 2 so as to integrally cover the front of the button 2 is rotatably attached to the nozzle case 3. The nozzle case 3 has, for example, a box shape with the back and bottom open, a width of 180 mm, and a depth of 80 m.
m and a height of about 100 mm.

The push plate 9 is, for example, an elongated plate having a width of about 60 mm and a length of about 100 mm. The push plate 9 has a spray hole 10 for a spray chemical sprayed from the spray nozzle 1 at a position corresponding to the spray nozzle 1 and has its own weight or The supply push button 2 is always held at a position where it comes into contact with the tip of the supply push button 2 by the elasticity of a separately provided spring. The diameter of the spray hole 10 is set to, for example, 12 to 15 mm.

In this way, the push plate 9 is attached to the nozzle case 3
The supply push button 2 protrudes forward from the nozzle and is obliquely provided in front of the spray nozzle 1. The stroke of movement due to the pressing of the push plate 9, that is, the supply push button 2 is pressed and sinks into the nozzle case 3. Set the stroke to about 7mm. The spray angle of the chemical from the spray nozzle 1 is set to, for example, about 10 °.

At the left and right positions of the push plate 9, projecting members 12 projecting forward from the push plate 9 are disposed as members for preventing malfunction of the supply push button 2. This protruding member
Numeral 12 is formed in a shape preferred by livestock, such as a chevron-shaped protrusion. As an example, as shown in FIG. 1, two substantially triangular-shaped ones are provided at the top and bottom, for a total of four, and the length of the protrusion is about 30 mm.

The shape of the projecting member 12 is not limited to the above-described substantially triangular pyramid shape, but may be a rectangular parallelepiped shape projecting forward from the nozzle case 3 as shown in FIG. Good.

Next, a method of arranging the spray nozzle 1 and the supply push button 2 in this way and installing the nozzle case 3 having the push plate 9 attached to the front thereof in a livestock hut such as a pig will be described. 5 and 6 show a first example, in which 13 is a U-shaped pedestal 13 having a back plate 13a as a mounting base, and a side plate of the pedestal 13 has a notch 13b for mounting the nozzle case 3.
Is formed in a vertically elongated shape, and a locking piece 15 is provided near the notch 13b.
Was mounted to be rotatable in the direction of the notch 13b. In the figure, reference numeral 17 denotes a notch into which the supply pipe 4 is inserted.

On the other hand, on the side of the nozzle case 3, a shaft 16 for mounting and reinforcing is provided horizontally, for example, in two stages vertically through a side plate.

Then, the back plate 13a of the pedestal 13 is fixed to the fence 14 of the livestock stable with bolts 18, the pedestal 13 is projected from the fence 14, and the nozzle case 3 is inserted into the pedestal 13 from above. Thus, the shaft 16 is inserted into the notch 13b, and the nozzle case 3 is placed on the pedestal 13 in a state where the nozzle case 3 is prevented from moving forward and backward. Therefore, if the locking piece 15 is rotated in the direction of the notch 13 b and locked to the shaft 16, the upward movement of the nozzle case 3 is also prevented by the locking piece 15, and the nozzle case 3 is fixed to the pedestal 13. .

FIGS. 7 and 8 show a second example of the installation method. A notch 3a having a thickness equal to the thickness of the fence 14 is provided on the upper surface plate of the nozzle case 3 so as to match the interval between the fences 14. Fence 14
Is inserted, and the fence 14 and the shaft 16 are contacted in a state of being orthogonal to each other. Then, U-bolt is used to connect the fence 14 and the shaft 16
At 19, the nozzle case 3 is fixed to the fence 14.

Next, the method of use will be described. Although water containing a chemical solution is constantly fed to the supply pipe 4 by pressure, the on-off valve 6 is pressed against the valve rod 5 by the elastic force of the spring 7. , The channel is in a closed state.

When a livestock such as a pig pushes the push plate 9 with the nose or the like, the push plate 9 pivots rearward around the upper pivot axis against the elasticity of the spring 9a, and pushes the supply push button 2. Press. As a result, the valve stem 5 pushes the on-off valve 6, and the on-off valve 6 moves backward against the elasticity of the spring 7, and the flow path in the supply pipe 4 opens. As a result, the spray chemical in the supply pipe 4 flows into the spray pipe 8 and is jetted from the spray nozzle 1 with a fluid pressure, and is jetted into the face of the livestock, particularly into the nasal cavity, and the livestock receives medication.

In this case, since the push plate 9 is formed in an elongated shape, the area where the nose of a livestock can contact is large, and the supply push button 2 can be pressed without pressing a specific part of the push plate 9. Further, since the supply push button 2 is disposed at a position below the spray nozzle 1, the movement stroke of the push plate 9 is small, and the supply push button 2 is pressed to open the on-off valve 6.
Therefore, if the livestock pushes the push plate 9 even slightly, the supply push button 2 is pushed and the spray chemical liquid is reliably ejected from the spray nozzle 1.

At this time, since the projecting members 12 protrude from the left and right sides of the push plate 9, parts other than the nose of the livestock come into contact with the nozzle case 3 when the livestock moves in front of the nozzle case 3. However, since the body contacts the protruding member 12 and does not contact the push plate 9, malfunction can be prevented. In addition, if the shape of the protruding member 12 is set to a shape preferred by livestock, it is easy to direct the nose in the direction of the push plate 9, and the interest of the livestock can be directed to the push plate 9 for a long period of time.

Further, the livestock has a habit of rubbing the body and face against the protruding member. However, the protruding member 12 can be used for that purpose, and can exert its independent function as a separate member from the push plate 9.

It is to be noted that livestock such as pigs are interested in a novelty and have a habit of coming into contact with the nose, so that the push plate 9 can be pushed by using this. After pressing and receiving the spray, the user feels comfortable and learns it.
You will press.

[0035]

As described above, the livestock spraying / dispensing apparatus of the present invention comprises the operating member of the feed push button formed by a push plate which is moved by being pushed by the nose of the livestock and pushes the feed push button. The feeding push button is reliably operated by the contact of the nose of the livestock. Further, since the protruding members projecting forward from the push plate are disposed at the left and right positions of the push plate, the push plate is prevented from being pushed by a part other than the nose of the livestock, and the malfunction of the supply push button can be prevented.

By forming the push plate in an elongated shape, the area where the livestock comes in contact with the plate is increased. Therefore, if the nose of the livestock comes into contact with any part of the push plate, the upper part of the push plate is removed. Since the push plate is easily rotated via the rotating portion, the spray liquid from the spray nozzle is reliably sprayed into the nasal cavity and around the nose of the livestock through the spray hole.

Further, since the supply push button directly presses the opening / closing valve in the supply pipe to move and open / close the opening / closing valve, the opening / closing of the opening / closing valve is mechanically performed, compared with the case where an electric mechanism is used. Malfunctions can be prevented and fewer failures are required.

Furthermore, by forming the protruding member into a shape that the livestock prefers, such as a chevron shape, it is possible to easily direct the nose of the livestock to the push plate and to keep the interest of the livestock for a long period of time. The domestic animal's habit of rubbing the protruding body by rubbing the nose or body against this member can be satisfied.
