Description

A water supply control apparatus of liquid feeder}

The present invention relates to a water supply control device for a liquid feed feeder, and more particularly, to control the amount of water supplied using a water meter to supply a fixed amount of water regardless of a water pressure difference. Water supply of a liquid feed feeder It's about the controller.

Typically, a feeder supplies feed and drinking water to livestock (hereinafter collectively referred to as 'livestock') such as pigs, cows, goats, sheep, etc. There are wet feeders that provide feed or dry feeders that provide feed and water separately.

On the other hand, feed has various types, particles or particle sizes, volume, viscosity, etc., and lumps or lumps occur due to moisture, requiring special management. provided in good condition. At this time, if the supply ratio of feed and water is not right, the feed becomes mush and is easily deteriorated, and the risk of disease is serious. Therefore, the spoiled feed has to be scooped out from the feed tray before the livestock eats it and thrown away, which is difficult to manage and manpower loss Since this is large and the loss of feed and water is severe, a device that can automatically control the supply of feed and water is desperately needed.

As a prior art for solving this problem, Korean Intellectual Property Office Publication No. 10-2018-0010614 (feed and water supply control method of a feeder) can be cited as an example.

The prior art is a feed and water supply control method of a feeder that controls the supply of feed and water supplied to a feed tray by automatically opening and closing the feed supply unit and the water supply unit, and the contact of the sensor to the liquid feed contained in the feed tray. When is released, the sensor outputs a "contact off" signal to the controller, and setting a set time in the controller to determine whether the sensor's "contact off" signal is continuously output during the set time. Automatically supplying feed and water to the feed tray by opening the supply unit and the water supply unit, and outputting a “contact on” signal to the controller when the sensor contacts the liquid feed supplied to the feed tray; , After determining whether the "contact on" signal of the sensor is continuously output for a set time set in the control unit, closing the feed supply unit and the water supply unit to block the supply of feed and water to the feed tray. make it a gist

However, the prior art uses a method in which feed and water are supplied during the time set in the control unit, and in this method, it is difficult to match the ratio of feed and water required by livestock, so that feed is left due to insufficient water in the feed tray or conversely, water is not supplied. Too much of this remains and often becomes a factor hindering the growth of livestock.

Even if the manager in the farmhouse has set the proper ratio of feed and water, the water pressure in the farm will inevitably change from time to time according to the amount of water that the livestock drink at the same time, so the manager has to observe the ratio of feed and water with interest and adjust it from time to time. can only

That is, when controlling the supply of water by time, a difference in water pressure occurs and the amount of water supplied for the set time is inevitably different when the water pressure is high and low, and therefore, the problem of not being able to supply the amount of water compared to the feed to the feed tray There is.

On the other hand, in the conventional feed dispensing device, since the amount of feed discharged when livestock is discharging feed is not constant, even if the amount of water preset in the control unit is accurate even under the same motion of the rotating shaft, the amount of feed is irregular, so the ratio of feed and water is not correct. There is a problem that doesn't.

In addition, when water is continuously discharged without stopping due to a malfunction of the solenoid valve or when there is no feed in the hopper, livestock continuously turn the feed dispensing lever to supply water, which causes an unnecessary amount of water to be wasted.

As shown in FIGS. 1 to 3, the liquid feed feeder of the present invention has a hopper 10 in which feed is stored and a feed discharge pipe 20 for discharging the stored feed is provided at the bottom, and the lower portion of the hopper 10 A feed tray 30 for containing feed discharged through the feed discharging pipe 20, a rotating shaft tube 50 installed vertically crossing the inner space of the hopper 10, and the rotating shaft tube 50 ) Is coupled to the lower end of the feed dispensing lever 32 for inducing livestock to rotate the rotating shaft tube 50 with a snout, provided inside the hopper 10 and supplying water to the feed support 30 It is composed of a water supply means to

At the lower end of the hopper 10, a feed discharge pipe 20 for discharging feed to the feed support 30 is provided. The feed discharge pipe 20 is located in the central portion of the feed support 30, and a feed support plate 120 is installed at the lower end of the feed discharge pipe 20 with the feed discharge port 122 therebetween, and the feed support plate ( 120) is coupled to the outer diameter of the rotary shaft tube 50 to rotate together with the rotary shaft tube 50. In addition, at least one forced feed discharge plate 124 is installed on the outer surface of the feed support plate 120 so that an accurate amount of feed is discharged as much as the rotation of the feed support plate 120.

When the feed dispensing lever 32 is pushed by the snout of the livestock, the rotating shaft tube 50 rotates, and in this process, the feed stored in the hopper 10 is discharged to the feed tray 30. That is, the feed dispensing lever 32 is connected to the rotary shaft tube 50 so that livestock rotate the feed dispensing lever 32 and feed is discharged to the feed support 30 .

The water supply means 60 is installed inside the hopper 10 and is a means provided for the purpose of supplying water to the feed support 20 according to the rotational motion of the rotary shaft tube 50.

The water supply means 60 includes a water supply pipe 62 connected to the rotary shaft pipe 30 . The water supply pipe 62 is connected to the water supply or supplies external water to the inside of the rotary shaft pipe 50 according to the pumping operation of a pump (not shown), through which water flows below the rotary shaft pipe 50. It is supplied to the positioned feed support 30.

That is, the water supply means 60 is a relatively simple configuration by using the rotating shaft tube 50 installed inside the hopper 10, rather than installing separate components outside the hopper 10 for water supply. and cost reduction effect can be realized.

A solenoid valve 64 is installed in the water supply pipe 62, and the solenoid valve 64 operates "off" according to the "on" operation and current cutoff with the current applied from the control unit 68, and operates the water supply pipe 62. By opening and closing, water is automatically supplied to the feed support (30).

A control means 70 is further provided in the water supply means 60.

The control means 70 is a means for automatically turning on and off the solenoid valve 64 by counting the number of rotations of the rotary shaft tube 50 .

The control means 70 counts the change in magnetic force of the magnet when the rotating shaft tube 50 rotates by pushing the feed dispensing lever 32 with the snout to feed the livestock, and sends a signal to the control unit 68 And, when the control unit 68 determines that the preset counter count has been reached, power is supplied to the solenoid valve 64 to open the water supply pipe 62.

The control unit 70 includes a case 72, a rotating plate 80, at least two or more magnets 82 and 84, and a detection sensor 86.

The case 72 is inserted into the outer diameter of the rotary shaft tube 50, so that it does not rotate with the rotary shaft tube 50 and maintains a fixed state, preferably horizontally across the hopper 10. Installed It is supported on the upper surface of the feed amount control table 14 at a certain distance apart, and a through hole 78 is formed below and an installation space 74 is formed inside. The case 72 is fixed to the feed amount control table 14 through a bracket 71.

The rotating plate 80 is located in the internal installation space 74 of the case 72 . The rotating plate 80 is coupled to the outer diameter of the rotating shaft tube 50 while being accommodated in the internal installation space 74 of the case 72 through the lower passage hole 78 of the case 72, (50) to perform a rotation operation. A hexagonal stopper 190 is preferably inserted between the rotary shaft tube 50 and the rotary plate 80 so that the rotational force of the rotary shaft tube 50 is transmitted to the rotary plate 80 .

A plurality of magnets are arranged on the outer surface of the rotating plate 80 at regular intervals, and the N-pole magnet 82 and the S-pole magnet 84 are alternately arranged so that each magnet has a different polarity. installed alternately.

A detection sensor unit 86 is installed in the internal installation space 74 of the case 72 . When the rotating plate 80 rotates while the sensor unit 86 is located under the rotating plate 80, the magnets 82 and 84 having different polarities installed on the outer surface of the rotating plate 80 While rotating and passing, the polarity of the magnets 82 and 84 or the phase difference of the magnet sensor is detected and counted, and then sent to the control unit 68. The detection method through a magnet has the advantage of being highly durable as it is resistant to dust and moisture.

On the other hand, the technology implementation method in which the detection sensor unit 86 detects the magnets 82 and 84 can be implemented in various ways, and below, two detection methods are representatively described.

As shown in FIG. 6, these are diagrams showing electrical flow between the magnets 82 and 84 and the detection sensor unit 86.

First, the detection sensor unit 86 may be a plurality of first and second detection sensors A and B. The first and second detection sensors A and B count the number of revolutions using phases (signal time differences).

That is, while the magnets 82 and 84 are arranged on the rotating plate 80, the first and second detection sensors A and B are arranged at regular intervals, but the intervals of the magnets are different.

In this case, in the initial state, the first detection sensor unit (A) senses the magnet 82, but the second detection sensor unit (B) is disposed between the magnets 82 and 84 so as not to detect the magnet 84. (A=1, B=0).

When the next rotating plate starts to rotate, both the first and second detection sensor units (A, B) are in a state in which the magnet is not detected (A=0, B=0)

If the next rotating plate continues to rotate, the first detection sensor unit does not detect the magnet, and the second detection sensor unit detects the magnet (A = 0, B = 1).

When the next rotating plate continues to rotate, both the first and second detection sensor units sense the magnet (A=1, B=1)

This detection sensor unit 86 is a sensor that does not detect the polarity of the magnet, and the control unit can count the number of rotations of the rotating plate through a signal time difference.

On the other hand, in another embodiment, the detection sensor unit 86 may be a single detection sensor as a sensor for detecting the polarity of a magnet.

At this time, the control unit counts the number of rotations of the rotating plate by using a voltage difference according to a change in polarity of a rotating magnet caused by the rotating motion of the rotating plate by the detection sensor.

Abrasion prevention device 140 is installed on the outer diameter of the feed amount control table 14 and the rotating shaft tube 50, and a stopper 142 for fixing the rotating shaft tube 50 is installed. The stopper 142 prevents the rotation shaft tube 50 from sagging, and accurately maintains the distance between the feed outlets in the correct position to accurately control the amount of feed discharged to the feed support 30, and the wear prevention device 140 ) has an effect of preventing wear of the rotating shaft tube 50 and the tube body due to friction to rub against the tube body installed on the feed amount control table 14 when the rotating shaft tube 50 rotates.

On the other hand, as shown in FIG. 4, the measurement part of the control means is not a magnet, but an opaque 182 and a transparent plate 184 are alternately formed radially along the outer surface of the rotating plate 180 to rotate the rotating shaft tube 180 You can also count the number.

Meanwhile, a water meter 66 is installed in the water supply pipe 62. When the water supply pipe 62 is opened by the operation of the solenoid valve 64, the water meter 66 measures the amount of water passing through the water supply pipe 62 and sends a signal to the control unit 68, and the control unit 68 When the preset supply amount of water and the supply amount of water measured by the water meter 66 match, the current supplied to the electronic valve 64 is cut off to turn the electronic valve 64 "off" so that a fixed amount of water is fed It is supplied to the pedestal 30.

That is, after setting the supply amount of water to be supplied to the feed tray 30 in the controller 68, supplying power to the solenoid valve 64 to operate the solenoid valve 64 to open the water supply pipe 62, the water meter 66 ) measures the amount of water passing through and sends a signal to the control unit 68, and then, when the supply amount of water set in the control unit 68 and the supply amount of water measured by the water meter 66 match, the solenoid valve 64 A fixed amount of water can be supplied to the feed tray 30 by blocking the supplied current and turning the solenoid valve 64 "off".

In this way, the supply of water is not controlled by time as in the prior art. By measuring the amount of water supplied and controlling the supply of water, it is possible to always supply a fixed amount of water regardless of the water pressure difference that may vary in real time for each barn of each livestock farm.

That is, when the water supply is controlled by time as in the prior art, when a water pressure difference occurs, the amount of water supplied for the set time is inevitably different when the water pressure is high and low, and therefore a fixed amount of water can be supplied to the feed tray 30. However, in the present invention, after measuring the amount of water passing through the water supply pipe 62 through the water meter 66, when the water supply amount preset in the control unit 68 is reached, the solenoid valve 64 is turned on. As the supply of water is cut off by "off", it is possible to always supply a fixed amount of water to the feed support 30 regardless of the difference in water pressure.

A water level sensor 90 is installed inside the feed support 30. The water level sensor 90 is a means for detecting water contained in the feed support 30.

The water level sensor 90 is used to forcibly stop the supply of water to prevent water from flowing continuously and overflowing to the feed tray 30 due to a failure of the solenoid valve 64. That is, when the water level sensor 90 detects that more than a certain amount of water is accumulated on the upper part of the feed stand 30 due to accumulation of foreign substances or failure of the electronic valve 64, the livestock turns the feed dispensing lever 32 to control the controller 68 ), it is possible to reduce unnecessary waste of water by not supplying water even when the set counter count is reached.

In addition, if moisture is not sensed by the water level sensor 90 depending on the occasion, the controller may be programmed to supply water intermittently.

It is preferable to install a height adjusting means on the water level sensor 90 so that the height of the water level sensor 90 can be adjusted.

In addition, the control unit 68 can be intermittently supplied with, for example, 1 liter of water every 30 minutes to prevent water shortage and induce more food intake. do.

In addition, since the amount of water supplied and the amount of feed can be accurately supplied, it is possible to check, manipulate, and monitor the supply status in real time from outside by linking with communication equipment, and to computerize records to have efficiency in management, etc. Use as ICT equipment this is possible

5 is a view showing another embodiment of the water supply means in the water supply control device of the liquid feed feeder of the present invention.

As shown in FIG. 5, the water supply pipe 62 constituting the water supply means 60 is not connected to the rotary shaft pipe 50 as in the above-described embodiment, but is provided separately on the outside of the hopper 10. An electronic valve 64 and a water meter 66 may be installed in the water supply pipe 62 so that water is directly supplied to the feed tray through the water supply pipe.

In addition, the rotating shaft tube 50 may be configured in the form of a tubular body or a rod in a blocked state.
