Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a feeding device that can capture specific cows and accurately manage feeding in a free-burn dairy facility.

[Prior art and its problems]

Generally, the feeding apparatus of a free-burn dairy farm facility is provided with a door feeder to prevent food theft.

A conventional door feeder has a fence-like stanchion with an openable door, a receiver installed near the door, and a collar-type transmitter attached to the cow. A code number corresponding to each cow is set in the transmitter and receiver, and the receiver receives the high frequency signal from the transmitter of the cow that approaches the designated door, and the door opens only when both code numbers match. , on the other hand, when the code numbers do not match, it operates to lock the door in the closed position. In other words,
Only when a cow corresponding to a predetermined stanchion is identified, the cow is allowed to feed, thereby preventing other cows from stealing food and performing accurate feeding management.

Incidentally, in a free-burn dairy farm, a device for capturing specific cows such as diseased cows, cows in heat, pregnant cows, etc. is also required, and this device is usually attached to the stanchion.

However, conventional door feeders consist of a door that can be opened and closed relative to the stanchion, and are opened and closed simply by checking a code number, so there is no possibility for further development. The device must be configured separately. For this reason, the structure of the feeding device including the stanchion becomes extremely complicated, and there is also the problem of increasing the size and significantly increasing the cost.

[Means for solving problems]

The present invention realizes the two functions of a door feeder and a device for capturing specific cattle through a rational configuration, and solves the problems existing in the prior art described above.

That is, the feeding device 1 for a free-burn dairy farm facility according to the present invention prevents the cow C located at the mooring location from feeding in the closed position P1 and allows feeding in the open position P2, and also allows the cow C located at the mooring location to feed at the open position P2. The opening/closing door 2 is linked to the movable stanchion pipe 22 so that the opening position P3 becomes the closed position P1, and the mooring position P4 becomes the open position P2, and the cow C identifies whether or not it is a cow corresponding to the mooring location. In addition, an identification means 3 for identifying whether or not the cow is a specific cow, a fixing means 4 capable of fixing the movable stanchion pipe 22 at the open position P3 or the mooring position P4, and an identification means 4 for the fixing means 4 when the cow is not identified. Open position P
3, and when the cow in question is identified and the specific cow is not identified, the fixation is released at all positions, and furthermore, when the cow in question is identified and the specific cow is identified, it is fixed at mooring position P4. It is characterized in that it is provided with a control means 5 for controlling.

[Effect]

Next, the operation of the present invention will be explained.

In the feeding device 1 according to the present invention, when a cow C approaches a mooring place, the identification means 3 identifies whether or not the cow C is a cow corresponding to the mooring place. In the case of the relevant cow, the locking of the opening/closing door 2 is released by the control means 5,
The opening/closing door 2 is moved to the open position P2 by the feeding movement of the cow C.
At the same time, the interlocking movable stanchion pipe 22 is displaced to the mooring position P4. Therefore,
Cow C can eat freely. Note that if the identification result by the identification means 3 is that the cow is not the relevant cow, the door 2 remains fixed at the closed position P1 and prevents the cow C from eating.

On the other hand, in the case of the relevant cow, the movable stanchion pipe 2
2 is displaced to the mooring position P4, the position is detected by the position detector 48 and sent to the identification means 3. When this signal is received, the identification means 3 identifies whether the cow is a specific cow or not, and in the case of a specific cow, the door 2 is fixed at the closed position P2 and the movable stanchion pipe 22 is fixed at the mooring position P4. Therefore, it is possible to allow only the relevant cattle to feed at each mooring location, and to capture specific cattle at the same time.

First, the overall structure of a stanchion including the present device 1 will be explained with reference to FIG.

The stanchion 20 in the free-burn dairy facility F has an upper connecting pipe 27 and a lower connecting pipe 28 separated from each other, and between each pipe 27 and 28, a plurality of partition pipes 21 and fixed stanchion pipes (hereinafter referred to as , fixed pipe)
23 is constructed in the form of a fence. In addition, a movable stanchion pipe (hereinafter referred to as a movable pipe) 2 formed in a substantially L shape is provided in the middle part of the fixed pipe 23.
The lower end portion 22a of 2 is rotatably attached. Further, one end of the L-shaped frame 2a of the opening/closing door 2 is rotatably attached to the fixed pipe 23 located below the lower end portion 22a. A blocking plate 2b is attached to the frame 2a to prevent the cow's head from entering from below. Further, the bent portion 22b of the movable pipe 22 and the bent portion 2c of the frame 2a are rotatably connected by a link 18, and the bent portion 22b of the movable pipe 22
A spring 19 is installed between b and the fixed pipe 23, and urges the movable pipe 22 toward the open position P3 (the position where the cow's head can enter). As a result, when the movable pipe 22 is in the mooring position P4 where it is substantially vertical, the door 2 is in the open position P2, and on the other hand, when the movable pipe 22 is in the open position P3 where it is inclined, the door 2 is in the closed position P1. On the other hand, a support pipe 29 is disposed in parallel above the upper connection pipe 27, and the support pipe 29 is supported by the upper connection pipe 27 via a connection fitting (not shown). On the other hand, a lever member 31 is rotatably attached to the upper end of the moving pipe 22, and a slide plate 32 is rotatably attached to the tip of this lever member 31. Therefore, due to the rotational displacement of the movable pipe 22, the slide plate 32 moves in parallel on the upper surface of the support pipe 29.

Further, a solenoid unit 33 constituting the fixing means 4 is attached to the support pipe 29, and this solenoid unit 33 is connected to a control device 35 via a switch 34. This switch 34 is always closed, but by manually opening it when mooring,
The lock is unlocked by cutting off the power supply to each solenoid unit 33. Further, a position detector 48 is provided which is fixed to the solenoid unit 33 and detects the position of the slide plate 32. This position detector 48 includes a dot 48a that projects downward and moves up and down, and when the slide plate 32 is present under the dot 48a, it goes up, and when it does not exist, it goes down (see FIG. 4). This position detector 4
Reference numeral 8 detects that the opening/closing door 2 is in the open position P2, and is connected to the computer 37.

On the other hand, a detector 3 is installed at the bottom of the moving pipe 22.
Attach 6. This detector 36 is connected to the computer 37, which in turn is connected to the control device 35. In addition, for the cow C, the detected device 3
8, these detectors 36, computer 3
7. The detected device 38 constitutes the identification means 2.

Next, each part will be explained in more detail.

First, the solenoid unit 33 will be explained with reference to FIGS. 2 to 4.

41 is connected to the support pipe 2 by bolts 42, 42.
This is a solenoid case fixed to 9. A recess 41a is formed in a portion of the case 41 that faces the upper surface of the support pipe 29.
Insert the slide plate 32 into 1a. Furthermore, a plunger 44 that is displaced by an excitation coil 43 is loosely inserted inside the case 41, and this plunger 44 is attracted and displaced downward in an excited state, and is returned upward by a return spring 45 in a de-energized state. It can be done.

Further, the slide plate 32 is provided with the plunger 4 when the movable pipe 22 is at the mooring position P4.
4 can be inserted into the locking hole 39a, and the moving pipe 22
A locking hole 39b is formed into which the plunger 44 can be inserted when is in the open position P3.

Therefore, the relationship between the solenoid unit 33 and the moving pipe 22 is as follows.

First, in the natural state, the movable pipe 22 is in the open position P3 due to the biasing action of the spring 19, and as shown on the left side in FIG.
The head of the cow C can fit between the partition pipe 21 and the partition pipe 21. In this state, solenoid unit 3
3 is energized, the plunger 44 is located downward, and is inserted into the locking hole 39b of the slide plate 32 and locked. On the other hand, if the excitation is released, the plunger 44 is located upward and is no longer locked to the slide plate 32. Therefore, in this case, if the cow C moves its head downward during feeding, the opening/closing door 2 will be in the open position P2, but if the cow C moves its head upward, it will return to the closed position P1, and the cow C will You can leave the standstill 20 by yourself. On the other hand, the moving pipe 22 is at the mooring position P4.
When the solenoid unit 33 is energized, the plunger 44 is urged downward and inserted into the locking hole 39a of the slide plate 32, thereby fixing the movable pipe 22 at the anchoring position P4.

FIG. 5 shows a modified embodiment in which the support pipe 29 shown in FIG. A notch 47 is formed in a part of the circumferential surface of the pipe 29. Thereby, the movable pipe 22 can be fixed by rotating the support pipe 29 and locking the locking piece 46 in the notch 47. In other words, it also has the function of manually turning and mooring the support pipe 29.

Next, the detector 36 and the detected device 38 constituting the identification means 3 will be explained with reference to FIGS. 8 and 9.

As shown in FIG. 8, the detector 36 includes a high frequency generating circuit 51 that generates a high frequency signal of a predetermined frequency, an amplifier 52 that amplifies the output signal of this circuit 51, a resonant circuit 53 that supplies the output signal of this amplifier 52, and this It consists of a detector 54 that detects the output signal of the circuit 53, and an amplifier 55 that amplifies the output of the detector 54 and shapes its waveform. The output signal of this amplifier 55 becomes the output of the detector 36.

On the other hand, the detected device 38 is attached to the lower part of a belt 61 that is hung around the neck of the cow C, as shown in FIGS. 6 and 7. Note that the code number of the cow C is engraved on the outer surface 38a of the detected device 38. Further, the circuit of this detected device 38 is a resonant circuit 6 as shown in FIG.
2. A rectifier circuit 63 that rectifies the output signal of this circuit 62 to obtain a direct current; an encoder 64 that outputs a coded bit signal by the output of this circuit 63; and is turned on and off by this bit signal. It consists of a switching circuit 65.

Therefore, a high frequency wave of a predetermined frequency is emitted from the resonant circuit 53 of the detector 36, and by attaching the detected device 38 to this resonant circuit 53, the detected device 38
The resonant circuit 62 receives this. The received signal is converted into a DC signal by a rectifier circuit 63 and supplied to an encoder 64, which outputs a bit signal corresponding to the code number of the cow C. This output causes the switching circuit 65 to
ON-OFF and change mutual inductance. Thus, the output of the detector 36 changes according to the code number, and each cow C can be identified. If such a detector 36 and detected device 38 are used, the detected device 3
8 does not require a power source, can be used semi-permanently, and has excellent durability and reliability.

On the other hand, the functions of the computer 37 and the control device 35 will be explained with reference to the flowchart of FIG.

First, the stationary number is initialized (step 100). Then, at the stanchion number N, the moving pipe 2 of the stanchion (mooring place)
2 is the release position P3 (step 101), its code number is read (step 102). In addition,
If the moving pipe 22 continues to be located at the mooring position P4, the next stanchion number is set (steps 103 and 104). On the other hand, it is determined whether the cow C is present in the stanchion (step 105). If the cow C is not present in the relevant stanchion, the solenoid unit 33 is energized, the plunger 44 is inserted into the locking hole 39b and locked, and the next stanchion number N+1 is set (steps 106, 104). Further, if a cow C is present in the stanchion, the identification means 3 identifies the code number of the cow C. If the cow is not the cow, the next stanchion number is set (step 104), and if the cow is the cow, the lock of the stanchion is released (steps 107, 108). Further, when the cow C is feeding and the stanchion is located at the mooring position P4 (step 109), the position detector 48 detects this, and the identification means 3 identifies whether it is a specific cow or not (step 109). Step 110). In the case of a specific cow, the solenoid unit 33 is energized and the plunger 44 is inserted into the locking hole 39a (step 111). Therefore, the moving pipe 22 is locked at the mooring position P4, and the cow C is captured. Then, the next stanchion number (N+1) is set and similar identification control is performed, and once this has been executed for all stanchions, the stanchion number is initialized (steps 112 and 1).
00).

Furthermore, by configuring the mechanism for capturing specific cattle as in the embodiment, specific cattle can be automatically identified and captured, making the capture work extremely easy.
It is efficient and can reliably capture specific cattle. In addition, since the capture is carried out at each mooring location, only the specific cows that are needed can be captured, and other cattle that do not need to be captured are not stressed in any way. Furthermore, it is not necessary to arrange them in a straight line structurally, and the degree of structural freedom and versatility can be significantly increased.

Although the embodiments have been described in detail above, the present invention is not limited to these embodiments. For example, any other means can be used as the identification means as long as it can identify the code number of each cow. In addition, any other fixing means can be used as long as it can fix the moving pipe at each position.
The quantity does not matter. Furthermore, the shape, arrangement, etc. of the moving pipe and the opening/closing door can be arbitrarily implemented.
In addition, the detailed structure, shape, arrangement, etc. can be arbitrarily changed without departing from the gist of the present invention.

[Effect of idea]

As described above, since the feeding device according to the present invention is rationally constructed by interlocking the door feeder mechanism and the specific cow capturing mechanism, the following effects can be obtained.

In a specific stanchion, reliable feeding management by preventing food theft and capture of specific cows such as pregnant cows can be performed at the same time, and management efficiency can be improved.

Since the door feeder function and the specific cattle capture function are configured in a linked manner, the device can be simplified, smaller, and lowered in cost, and can be easily implemented using existing facilities.
