Description

Milking quantity measuring device {measurement apparatus for milking quantity}

The present invention relates to a milking quantity measuring device.

An electronic flow meter that can measure the milking rate of cows is installed and operated in general milking farms. However, it is possible to check which individual measured how much flow rate only in the field, and only the farmer who can identify the cow by looking at the appearance of the cow can confirm the approximate cow number and milking amount.

Recently, there are many cases where professional milkers who act as professional milking agents (helpers) do milking for them, but in this case, it is difficult to tell what kind of cow it is, and it is difficult to determine how much milk has been milked.

When purchasing an expensive system, it reads the RFID of milked livestock and automatically records the individual number and flow rate, but the reality is that most farms avoid purchasing it because it costs about 600 to 100 million won.

Therefore, a mechanical flow meter that mechanically separates 1/10 of the flow rate and records the flow rate based on the separated milk amount was used in livestock farms.

Alternatively, a method of checking the amount of milk on a scale by keeping the milk in a large glass bottle was also used. These, conventional methods have the inconvenience of manually recording the measurement data. Accordingly, an electronic flow meter capable of automatically measuring the milking amount is being researched.

Republic of Korea Patent Registration No. 10-0481011 (2005.03.25.) Republic of Korea Patent Publication No. 10-2004-23871 (2004.03.20.)

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art can easily carry out the present invention. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Throughout the specification, like reference numerals are assigned to similar parts.

The milking amount measuring device of the present invention connects artificial electrical wiring or other devices to the electronic flow meter so that the flow rate measurement value of the product group can be checked simply without causing a problem to the product supplier. In other words, the integration of RFID recognition system and flow measurement technology makes it possible to store milking data in a computerized record at a low cost.

The milk (100g-200g) filled in the upper space of the milking container is discharged using the on/off valve and the number of times it is discharged is measured. By measuring the vacuum pressure controlled by the operation of the on/off valve, the number of operations of the opening/closing part can be checked. Using this principle, the flow rate of the other device can be measured only by monitoring the pressure of the external vacuum pipe without connecting the magnetic flowmeter and a physical line. and there is no influence on each other, so there is no disagreement with the installer.

The measurement error is generated in proportion to the amount of milk flowing in, that is, the flow rate. If milk enters at a constant flow rate, if the discharge location and speed are constant, it will have a fairly precise measurement value. However, if the amount of milk entering the space increases due to the high flow rate, if milk is discharged for a specified period of time, the discharge will be proportional to the increase in the amount of milk flowing in. As the number increases, the measurement error increases. Conversely, when the flow rate is slowed, there is a problem in that the amount of discharge decreases and the measurement error increases again.

In order to overcome this, it has a function to overcome the measurement error with respect to the flow rate, and one of these functions is to control the level of discharge in relation to the flow rate of milk.

If the flow rate is too fast, the amount of pumped amount is 200 g by adjusting the time for discharging the milk, and if the flow rate is slow, the discharge time is proportionally reduced and pumped by 100 g to minimize the error.

By recording the pressure change time of the vacuum pipe, the operation time of the on/off valve and the opening/closing part and the ratio of the discharge amount are secured, and a table of the discharge time by discharge time is secured so that the flow rate measured only by the operation of the device can be precisely secured

By properly combining the operation frequency and operation time of the on/off valve and the opening/closing part, the indirect milking amount is obtained by checking the one-time discharge according to the product, and the data is stored on the server and the user service is provided by the network system in place. make it possible

It allows semi-automated milking equipment to be fully automated at low cost.

Then, an apparatus for measuring milking amount according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4 .

It is a state diagram, and FIG. 4 is a state diagram showing a state in which the sealing packing of FIG. 2 is separated from the periphery of the falling hole.

1 to 4, the milking quantity measuring device according to this embodiment includes a milking barrel 100, an opening/closing unit 200, an opening/closing valve 300, a vacuum hose 400, and a vacuum sensor 500, , the vacuum sensor 500 detects whether there is a vacuum in the vacuum hose 400 and calculates the amount of milk discharged.

The milking tube 100 is empty inside. A partition wall 103 having a drop hole 103a formed in the center is disposed inside the milking tube 100 . The edge of the partition wall 103 is coupled to the inner surface of the milking tube 100 . The inside of the milking tube 100 is divided into an upper space 100a and a lower space by a partition wall 103 . The cross-sectional area of the upper space 100a is larger than the cross-sectional area of the lower space 100b. The upper surface 103b of the partition wall 103 is formed to be inclined downward in the direction of the central drop hole 103a from the edge.

An inlet 101 connected to the upper space 100a and introducing milk into the upper space 100a is formed on the upper surface of the milking barrel 100 . The milk introduced into the upper space 100a is introduced into the lower space 100b through the drop hole 103a. At this time, since the upper surface of the partition wall 103 is inclined, the milk of the upper space 100a is guided to the drop hole 103a along the slope of the partition wall 103 and is easily discharged, and the lower space 100b in the upper space 100a ) to completely drain the milk. The lower surface of the partition wall 103 is not inclined and forms a right angle with the circumferential surface of the lower space 100b.

A discharge port 102 connected to the lower space 100b is formed on the lower surface of the milking tube 100 . The milk in the lower space 100b is discharged to the outside of the milking container 100 through the outlet 102 .

Milking barrel 100 may be made of metal or plastic. On the other hand, a portion of the milking tube 100 may be formed transparently. Accordingly, the manager can check the flow state of the milk introduced into the milking container 100 from the outside of the milking container 100 .

The opening/closing unit 200 includes a solenoid 201, a sealing packing 202, and an elastic member 203, and opens or closes the drop hole 103a. When the falling hole 103a is opened, the milk in the upper space 100a is introduced into the lower space 100b through the falling hole 103a. However, when the drop hole 103a is closed, the milk in the upper space 100a does not flow into the lower space 100b.

It is arranged in the center of the lower surface of the milking tube 100 of the solenoid 201, and at least a portion is located in the lower space (100b). The rod 201a of the solenoid 201 is positioned on the same line as the center of the drop hole 103a. The rod 201a may be raised and lowered.

The sealing packing 202 is coupled to the end of the rod 201a. The shape of the sealing packing 202 in a plan view is circular, and the diameter of the sealing packing 202 is larger than the diameter of the falling hole 103a. Accordingly, the edge of the sealing packing 202 may be in contact with the peripheral portion of the drop hole 103a on the lower surface of the partition wall 103 . The sealing packing 202 may be made of rubber or the like. The sealing packing 202 may be separated from the lower surface of the partition wall 103 as the rod 201a descends. At this time, the drop hole 103a is opened.

The elastic member 203 includes a coil spring. The elastic member 203 is disposed along the circumference of the rod 201a, the upper end is in contact with the sealing packing 202, and the lower end is in contact with the solenoid 201. The elastic member 203 is compressed by the elastic member 203 when the rod 201a descends, thereby compressing the elastic force. However, when no current flows in the solenoid 201 , the elastic force of the compressed elastic member 203 is restored as the descent of the rod 201a is released to apply the elastic force to the sealing packing 202 . At this time, the rod 201a rises and the sealing packing 202 is in close contact with the lower surface of the partition wall 103 while the edge of the sealing packing 202 is in close contact with the peripheral portion of the falling hole 103a.

The opening/closing valve 300 is disposed outside the milking barrel 100 and is connected to the opening/closing unit 200 by a vacuum hose 400 . The opening/closing valve 300 is opened and closed to form a vacuum pressure in the opening/closing unit 200 . The rod 201a is lowered by the formation of vacuum pressure.

The vacuum sensor 500 is disposed on the vacuum hose 400 and detects whether there is a vacuum in the vacuum hose 400 .

The milking amount measuring device according to the present embodiment further includes an upper water level sensor 104 and a lower water level sensor 105 .

The upper water level sensor 104 and the lower water level sensor 105 are disposed at intervals in the upper space 100a in the vertical direction and are connected to the on/off valve 300 . The upper water level sensor 104 is located in the upper part of the upper space 100a and is close to the inner upper surface. It is located in the lower part of the upper space 100a of the lower water level sensor 105 and is close to the upper surface of the partition wall 103 . The upper water level sensor 104 detects milk filling the upper space 100a. The lower water level sensor 105 detects the milk level lowering in the upper space 100a.

Here, when the upper water level sensor 104 detects milk, the signal is transmitted to the on-off valve 300 , and the on-off valve 300 operates the vacuum hose 400 so that the sealing packing 202 is separated from the partition wall 103 . ) to create a vacuum pressure. As the rod (201a) is lowered by vacuum pressure, the sealing packing (202) is separated from the partition wall (103). The milk in the upper space 100a falls into the lower space 100b through the drop hole 103a, and the milk in the lower space 100b is discharged through the outlet 102. The opening/closing valve 300 allows the vacuum hose 400 to maintain a vacuum state while milk falls from the upper space 100a to the lower space 100b.

As the milk falls from the upper space 100a to the lower space 100b, the milk level in the upper space 100a is lowered. At this time, if the lower water level sensor 105 does not detect the milk, the milk is completely discharged from the upper space 100a to the lower space 100b. The lower water level sensor 105 transmits the signal to the on/off valve 300 , and the on/off valve 300 releases the vacuum pressure of the vacuum hose 400 . At this time, as the compressed elastic member 203 applies an elastic force to the sealing packing 202, the rod 201a moves in the direction of the partition wall 103, and the sealing packing 202 is in close contact with the lower surface of the partition wall 103. The fall hole 103a is closed. Then, milk is introduced again into the upper space 100a through the inlet 101 .

By sensing the vacuum time in the vacuum hose 400 maintaining the vacuum by the on/off valve 300 , the amount of milk discharged through the outlet 102 is calculated.

In addition, the vacuum sensor 500 detects the number of times the vacuum is maintained or the vacuum is released by the on/off valve 300 to calculate the amount of milk discharged through the outlet 102 .

Accordingly, by measuring the flow rate proportional to the flow rate of milk flowing into the upper space 100a and finely adjusting the time to open the drop hole 103a in preparation for the flow rate, the amount of milk discharged to the outlet 102 is close to 200 mg can make it The amount of milk can be calculated by multiplying the amount of milk discharged by 200 mg by the number of vacuums.

Therefore, when milk is discharged through the outlet 102 , the vacuum hose 400 is vacuumed to measure the milk output, thereby preventing an electrical malfunction. And since the milk quantity is calculated while discharging the milk filled in the milking trough, it is possible to accurately measure the milking quantity.

Accordingly, through the process of installing the vacuum sensor 500 in the vacuum hose 400 between the opening/closing unit 200 and the opening/closing valve 300, it is possible to easily check the amount of milk discharged from the milking container 100, and the vacuum sensor 500 ), by measuring the milk discharge proportional to whether the vacuum hose 400 is vacuumed, it is possible to accurately calculate the milk discharge amount.

In addition, the opening and closing unit 200 is operated in a vacuum method to prevent malfunction due to electrical faults, and in particular, due to this malfunction prevention, a predetermined amount of milk filled in the milking container can be accurately discharged. While the range is minimized, product reliability is improved.
