The present invention relates to a sensor unit of a probe type milking system, and more particularly, to a sensor unit applied to a probe type milking flowmeter having the advantage of accurately measuring the milk amount milked from an individual cow.

There are many types of milking flowmeters used in the related art, but the present invention can be applied to a digitized probe milking system which is able to measure milking flow accurately among them, and forms the mainstream of the milking system currently in use.

Probe-type milking flowmeter used in the prior art is a milking unit milked by a constant vacuum pressure from each cow's individual flows into the milking system through the crude oil transfer hose, the milk introduced into the milking system is a sensor unit provided inside the milking system The milking amount was measured electronically by calculating the crude oil flow time as crude oil was simultaneously brought into contact with two electrical probe rods installed inside the sensor unit while passing through.

In such a milking flowmeter for the probe type, the most important factor for the accurate measurement of milking flow is a sensor unit in which a probe rod for detecting the flow of crude oil is installed.

That is, since the sensor unit corresponds to the milking flow detection unit that detects the flow of milk milked and automatically calculates the milking amount in the microcomputer, only the flow of crude oil introduced into the inside of the probe rod is accurately detected. It is an important part to allow accurate detection of flow and accurate milking amount calculation, and it is desirable to have a simple structure that can be discharged immediately after the milk is introduced and the flow is detected and discharged to the oil storage unit. something to do.

In addition, in the case of the sensor unit, it is preferable that the internal structure of the sensor unit is simple and prevents pressure loss during inflow and outflow of crude oil in order to prevent accumulation of petroleum and the like due to long-term use.

In other words, the vacuum and atmospheric pressure alternately act to stimulate the cow's nipples, so that milk is repeatedly milked by inhaling and resting the milk, so that the fluid flows in a two-phase mixture of crude oil and air. It is preferable that the sensor unit is configured to minimize the occurrence of errors in the probe rod used to detect the flow of flow in the sensor unit.

In order to satisfy such conditions, the present inventors have previously devised a milking flowmeter, and a cross-sectional state of the sensor unit applied to the conventional milking flowmeter of the present inventors is shown in FIG. 1.

The sensor unit 10 applied to the conventional milking probe flowmeter shown in FIG. 1 can accurately detect only the flow of crude oil in the flow of air and crude oil, which has emerged as the biggest problem among several disadvantages of the probe flowmeter. In order to solve the problem that was not present, the probe rods 50 and 51 installed inside and inside the probe space part 22 are installed up and down to solve the problem of erroneously detecting crude oil flow from the wetting effect of air flowing with crude oil. The milking system was provided to measure the exact milking amount.

However, after the milked crude oil moving under a constant vacuum pressure flows into the sensor unit 10 of the flowmeter, the crude oil and the air are separated, and a predetermined vortex phenomenon occurs inside the probe space 22. (22) Vortex generation induces a pressure loss of the device, and there is a possibility that an error may occur in the reading value of the milking system due to the pressure loss, and also always close to the breast of the cow at a uniform pressure to stimulate the nipples. In view of the problem that breast cancer may develop due to an irregular vacuum pressure action on the cow's nipple by applying a higher pressure to compensate for the pressure lost to the liner, the present inventors have proposed a probe space part of a conventional sensor unit ( 22) It can prevent the pressure loss in the inside, it is possible to smoothly wash the stone that can be caught around the probe rods 50, 51 installed inside the probe space portion 22 The need of the development of the sensor unit 10 is soybean that came to devise the present invention.

That is, the present invention provides a sensor unit for preventing the vortex phenomenon, which causes the pressure loss inside the sensor unit, which can solve the problem of irregular vacuum pressure generation as well as accurate milking amount measurement as well as the onset of breast cancer of cows. The aim is to provide sensor units for probe milking systems.

In addition, the present invention is to provide a sensor unit of the milking system that is configured to facilitate the removal of the stalactites that can be caught in the probe rod to probe the flow of crude oil to prevent inaccurate crude oil flow measurement due to long-term use There is this.

In order to achieve the above object, the sensor unit of the probe flow meter according to the present invention is provided with an inlet through which milked milk is introduced, and an outlet through which the crude oil introduced from the inlet is discharged at one end and the tartan, respectively, In the sensor unit of the probe flow meter having a probe space portion for detecting the flow of milk milk is installed between a plurality of probes, the sensor unit is coupled to the upper surface of the probe space and the bottom of the upper block is formed The inlet and outlet are separated into a lower block formed on both sides so that crude oil is introduced into the probe space, but the probe space has a predetermined width and length at the bottom and is concave to an inner side to be concave at a predetermined depth. Is made, between the inlet and outlet of the lower block protrudes a predetermined height inside the probe space portion Thus, the crude oil guide protrusion having a predetermined shape is formed to protrude and discharge the crude oil smoothly, and thus the crude oil introduced into the probe space is probed, and thus the characteristic structure can be smoothly discharged without causing the vortex phenomenon.

In particular, the crude oil guide projection is formed to extend a vertical section of a predetermined height on the inlet side so that the top end is spaced a certain distance from the elliptical inner circumference of the probe space to maintain a smooth flow along the elliptical inner circumferential surface of the probe space portion is introduced into the inlet A straight inclined surface is formed from the uppermost end of the vertical section to the inlet side of the discharge port through which crude oil is discharged, and the inclined surface has a right triangle shape having one of a plurality of probes configured to effectively probe the crude oil flow. When the upper block and the lower block is separated at the time is configured to facilitate the washing of the stone, foreign matters and the like formed inside the probe space.

Hereinafter, a detailed description of the sensor unit of the probe milking system according to the present invention with reference to the accompanying drawings.

That is, Figure 2 is a combined perspective view of a single unit state of the sensor unit of the probe milking system according to the present invention, Figure 3 is an exploded perspective view of a single unit of the sensor unit of FIG.

It is the part that directly detects time.

In the detailed description of the present invention, description of the overall configuration of the milking system will be omitted, and the present invention will be limited to the present invention.

As shown in the drawings, the milking system sensor unit 10 according to the present invention is discharged again after the milk flow is detected by the two probe rods 50, 51 installed inside the milked milk is introduced into the crude oil collecting unit ( (Not shown).

In particular, the sensor unit 10 for the probe type milking system according to the present invention is configured to be separated into upper and lower blocks 20 and 30 having a rectangular parallelepiped shape, and the milk block flows through the upper block 20 to the probe rod. Probing spaces 22 through which crude oil is probed are provided by the 50 and 51, and the lower block 30 is formed with an inlet 36 through which crude oil is introduced and an outlet 37 through which the introduced crude oil is discharged again. ,

In addition, between the outlet side of the inlet port 36 and the inlet side of the discharge port 37, a crude oil guide protrusion 32 having a right triangle shape is formed, and the crude oil guide protrusion 32 formed in the lower block 30 is formed. The probe space portion 22 formed on the bottom surface of the upper block 20 so as to be located inward has a predetermined width and length and has a structure that is processed into an elliptical structure having a predetermined depth inward.

Side cross-sectional and side perspective views of a state in which the lower block 30 and the upper block 20 are integrally used are shown in FIGS. 4 and 5.

As shown in FIGS. 4 and 5, the probe space portion 22 which is recessed in a predetermined depth inward from the bottom of the upper block 20 is a crude oil guide projection of the lower block 30 fitted into the inner portion. The upper end of the (32) is configured to maintain a predetermined interval from the inner circumference of the oval so that the crude oil can be transported, one side of the crude oil guide projection 32 formed on the outlet side of the crude oil inlet (36) is almost vertical It is formed of a cross-section 33, a straight inclined surface 35 is formed from the upper end of the vertical cross-section 33 to the inlet side edge of the discharge port 37 of the probe space 22 in a constant vacuum pressure state The crude oil injected while being introduced into the inside is formed in a shape that can be immediately discharged to the discharge port 37 without vortices occurring inside the space which is somewhat enlarged.

In addition, the probe space portion 22 is provided with two probe rods 50 and 51 to expose the flow of crude oil, one of the probe rod 51 is the inner peripheral surface of the probe space portion 22 It is installed on one side, and another probe rod 50 is installed on the inclined surface 35 of the crude oil guide projection portion 32 of the lower block 30 to the elliptical inner peripheral surface and the inclined surface 35 of the probe space portion 22 It is configured to detect the flow by the crude oil flowing along.

In addition, the crude oil introduced from the crude oil inlet 36 flows into the vertical space 33 of the crude oil guide protrusion 32 so that the same conditions as those of the crude oil inlet pipe 40 can be maintained while the crude oil is introduced into the probe space 22. A curved surface portion 34 having the same level as the inner circumference of the pipe 40 is formed to enable smooth inflow of crude oil, and the height of the vertical section 33 of the crude oil guide projection 32 is the inlet 36 and the outlet. It is formed to have a length substantially equal to the distance between the center of the (37) is the crude oil guide projection 32 is made of a right triangle structure.

On the other hand, the operation of the sensor unit of the probe milking system according to the present invention having the above-described configuration and shape will be described.

The sensor unit of the probe milking system according to the present invention has a right triangle triangle-shaped crude oil guide protrusion 32 protrudes in the probe space 22 into which the milk milked from the breast of each cow is introduced while maintaining a constant vacuum pressure. The crude oil flowing into the pulsating state is injected into the inside of the probe space portion 22 wider than the cross-sectional area of the inlet 36, and is injected momentarily, the injected crude oil of the inner circumferential surface of the probe space portion 22 and the crude oil guide protrusion 32 The flow is sensed by the probe rods 50 and 51 respectively installed on the inclined surface 35, and the gas introduced together with the crude oil meets the outlet 37 at the upper end of the wide probe space 22. As natural gas flow is maintained and discharged through the discharge port, separate vortex phenomenon does not occur for crude oil introduced together.

That is, the milked crude oil stream maintains the same flow state to the end of the vertical section 33 of the crude oil guide projection 32 through the inlet 36 while maintaining the pulsation state of the continuous pulse wave mixed with air and crude oil. The crude oil and air are separated from each other outside the vertical section 33, and some crude oil flows along the inner circumferential surface of the elliptical probe space portion 22 by Winsim's force, and some crude oil is inclined surface 35 of the crude oil guide protrusion 32. Naturally flowing along the passage between the two probe rods 50 and 51 respectively installed on the inner circumferential surface and the inclined surface 35 of the elliptical, wherein the two probe rods by the crude oil flowing between the two probe rods 50 and 51 The mutual current is conducted so that a constant reference voltage flows and the transit time of the crude oil is measured so that the milking amount can be calculated in the milking system, and the air introduced into the probe space 22 is separated from the crude oil. By naturally discharging toward the crude oil discharge port 37 while maintaining its own gas phase flow so as to prevent unnecessary vortices from occurring inside the probe space 22.

In this way, by preventing the vortex of the gas introduced with the crude oil inside the probe space 22, it is possible to prevent the pressure loss in the crude oil transfer hose to which a constant reference vacuum pressure is applied, so as to be in close contact with the nipples of each cow and a predetermined stimulus Through the milking liner milking is always made so that the milking under a uniform vacuum state is maintained.

Therefore, when pressure loss occurs in a crude oil transfer hose or milking system as in the prior art, breast cancer is applied to a cow's nipple that acts above the standard pressure by increasing the pressure on the cow's nipple due to an increase in internal pressure applied to the liner where milk is milked. This can solve problems that may occur.

In addition, by using the centrifugal force of the crude oil and the diffusion force of the gas in the inside of the probe space 22 to suppress the generation of vortex, it is possible to prevent equipment damage of the milking system to maintain the high accuracy according to the increase in internal pressure, This prevents an error from occurring in the electrical signal reading the transit time of crude oil so that accurate crude oil quantity measurement can be made.

In addition, the upper block 20 constituting the probe space 22 and the lower block 30 formed with the inlet 36, the outlet 37 and the crude oil guide protrusion 32 are configured to be separated from each other, if necessary, the upper block. Separating the 20 and the lower block 30 to remove the stones that can be caught on the probe rods 50, 51 from time to time to prevent the production of various bacteria around the probe to enable the production of high-quality crude oil and at the same time To reduce the error of oil quantity detection that can occur in the

As described above, the sensor unit of the probe type milking system according to the present invention improves the precision of the flow meter by improving the precision of the flow meter by preventing vortices from occurring in the probe space part by moving the pulsation through the structure change of the probe space part. In order to provide a flow meter, irregular vacuum pressure due to the pressure loss is applied to the breast of the cow to prevent the risk of developing various diseases.
