TECHNICAL FIELD OF THE INVENTION
The present invention relates to an isolating device for an automatic feeding machine for isolating a livestock animal from other livestock animals.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, an automatic baby feeding machine used for breeding livestock such as a large number of calves is provided with nipples for feeding according to the height of the calf on the wall of the calf tress, and FRP (fiber reinforced plastic) on both sides of the nipple. There is a feeding box with a board made of steel. Since this feeding box is provided, a calf having a large physique and an advanced age after parturition (hereinafter referred to as an upper calf) can be used for feeding a young calf (hereinafter referred to as a small calf) sucking from the feeding box. , The lower calves) were considered less likely to steal milk substitutes.
[0003]
[Problems to be solved by the invention]
However, the applicants have observed from the behavior of the calf bun that the calf living together is being expelled by the upper calf at a frequency of 16.4% from the entrance of the feeding box which is always open. I made it.
[0004]
If such milk replacer is continuously intercepted, lower calves may become stunted due to insufficient feeding, and upper calves may suffer from diarrhea or acute bloat due to excessive intake of milk replacer. May cause illness.
[0005]
The problem to be solved by the present invention is to provide an isolation device for an automatic baby machine which prevents the expulsion of livestock such as a calf during feeding.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, an isolation device for an automatic feeding machine of the present invention is provided in an automatic feeding machine that has a feeding port at a front portion of a feeding space and feeds livestock entering the feeding space. A sensor provided in the feeding space portion, a door portion provided at the rear of the feeding space portion and capable of opening and closing, and detecting the exit and entry of the livestock by the sensor, the door. And isolation means for opening and closing the unit.
[0007]
The nursing space refers to a portion where livestock is present at the time of nursing and the surrounding space, and the nursing mouth refers to the one in which milk replacer comes out when the calf sucks in the mouth. The sensors provided in the feeding space include not only mechanical sensors but also optical sensors. In addition, the isolation means includes one that is mechanically or electrically connected to the sensor and that mechanically or electrically activates the door.
[0008]
When livestock enters the feeding space, the sensor detects this. Next, the isolation means operates to close the door. Livestock feed in this state. Even if another livestock tries to push out the rearing livestock from behind, it cannot enter the feeding space due to the door, and the livestocks can feed slowly until the end of feeding. it can.
[0009]
When the livestock retreats backward from the feeding space after the end of feeding, the sensor detects this and the isolation means operates to open the door. Livestock can exit through the door. Livestock can be sufficiently fed in this way.
[0010]
In the sensor, a rotatable tread plate is provided on the floor, and the movement of the livestock is detected by the rotation of the tread plate, and a link mechanism for connecting the tread plate and the door portion is detected by the rotation of the tread plate. It is also possible to provide. As the link mechanism, for example, a combination of a wire rope, a pulley, a rotating rod, a cam, a gear, and the like can be used.
[0011]
When the livestock enters the front part of the feeding space, the tread plate is rotated by the weight of the livestock, and the approach of the livestock is detected. When the tread rotates, the link mechanism operates and the door closes. The ratio between the rotation angle of the door and the rotation angle of the tread plate can be adjusted by connecting the link mechanism. For example, when the weight of the livestock is heavy, the kinetic energy increases, so that the stroke of the tread plate can be reduced and the stroke of the door can be increased, and the livestock can move forward and backward without feeling uncomfortable.
[0012]
Preferably, the door is opened and closed up and down. Up and down opening and closing means that the door moves up and down without protruding to the left and right of the feeding space, and includes not only the case of turning but also the case of sliding.
[0013]
Since the door part opens and closes up and down, the door does not hit other livestock on the left and right sides of the door part, and the stress on the livestock is reduced. When a plurality of automatic feeding machines and separation devices are provided, the pitch between adjacent feeding spaces can be reduced, and the breeding room can be effectively used.
[0014]
It is preferable that the door is formed to be rotatable. If the door is slid, if the door being opened and closed accidentally collides with livestock, the lower end of the door collides with livestock. Because of the collision, the impact is reduced.
[0015]
It is preferable to provide an urging means for urging the door in a direction to open the door. Since the urging means is provided, it is possible to reduce the impact when the door is opened and closed, and to prevent a collision sound and a vibration.
[0016]
It is preferable that a counterweight is provided on the door, and the counterweight is opened independently of the link mechanism. Independent from the link mechanism refers to a state in which the connection between the door and the link mechanism is removed and only the door is rotatable.
[0017]
Since the doors are independently opened, the doors do not close even if the link mechanism breaks down, thereby preventing the doors from colliding with livestock at the lower part of the doors.
[0018]

[0040]
When the calf has entered the feeding space 2 and the front leg rests on the rear part of the tread plate 8, the front end of the tread plate 8 moves only slightly downward due to bending of the tread plate 8 and extension of the power transmission wires 13 and 14. , The shielding plate 25 is only slightly closed. Therefore, the calf can enter the feeding space portion 2 without anxiety toward the front without any fear.
[0041]
When the calf further moves forward, the angle member 11 is provided on the front side of the tread plate 8, so that the bending of the tread plate 8 becomes small, and the front end of the tread plate 8 moves largely downward.
[0042]
As shown in FIGS. 3 and 4, when the front end of the step board 8 is lowered, the unequal-length rotating lever 18 rotates about 90 ° via the power transmission wire 13 so as to lower the short arm 19 side. At the same time, the long arm 20 rotates upward, the door 6 is pulled and rotated via the power transmission wire 14, and the door 6 is closed. As described above, the link mechanism 7 can close the door 6 by detecting the calf riding on the front side of the tread plate 8 of the sensor 5 by the rotation of the tread plate 8.
[0043]
Since the door portion 6 is provided with a tension spring 41 which extends when the door portion 6 closes and pulls the door portion 6, the main frames 21 and 22 are connected to the rear portions when the door portion 6 changes from the open state to the closed state. Violent collision with the frame 31 is prevented. Therefore, the calf that has entered the feeding space 2 does not have a fear or panic.
[0044]
When the calf finishes feeding and starts to retreat in the feeding space 2, the front end of the tread 8 starts to rise, the power transmission wire 14 becomes loose, and the door 6 automatically opens due to the weight of the balance weight 27. Further, when the door 6 is opened, the tension spring 41 is urged, so that the door 6 is prevented from being opened late due to the inertia of the balance weight 27, and is quickly opened in accordance with the retreat of the calf. Is prevented from colliding with the shielding plate 25 of the door portion 6. As described above, the link mechanism 7 can detect that the calf has retreated from the front side of the tread plate 8 of the sensor 5 by rotating the tread plate 8 and open the door portion 6.
[0045]
When the calf completely exits the feeding space 2, the tread rises to the initial state as shown in FIG. 3, and the calf waits for another calf.
[0046]
