Abstract

PURPOSE:To sample a milk at a specific ratio for the initial milking period to the end, by branching and flowing milk flowing through an inflow pipe from the underside upward into a discharge pipe while ejecting and dispersing the milk. CONSTITUTION:An inflow pipe 5 is connected to the side of a claw unit and a discharge outlet 13 is connected to a tap of a cow's milk pipe to fix a sampling bottle 19 to a mounting port 17. Drawn milk is passed through the inflow pipe 5, led into a container 2, horizontally dispersed by a dispersing cone 7 and partially flowed into a receiving pipe 9. The residual milk is discharged from the discharge outlet 13. The milk flowing into the receiving pipe 9 is conically dispersed by a cone 15 and partially flowed into a discharge pipe 16. The residual milk is discharged from the discharge outlet 13. The milk flowing into the discharge pipe 16 in an amount of about 0.2% based on the milking amount is flowed into the sample bottle 19.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for sampling milk flowing into the milk piping of a pipeline milker.

One Prior Art In a pipeline milker, milk from a cow flows through a milk tube into a milk pipe. When managing dairy cows, it is important to inspect the amount and quality of milk produced by each cow, and to do so, it is necessary to sample the milk, but the ratio of components in milk differs between the early and final stages of milking. Therefore, it is not possible to sample all at once during milking. In pipeline milkers, the expressed milk flows into the milk pipe one after another and is mixed with other milk, so it is not possible to extract a sample after all the milk has been expressed. Conventionally, sampling was performed by bypassing a portion of the milk flowing through the milk tube and storing it in a measuring container, from which the sample was extracted.

Problems to be Solved by the Invention - It is sufficient to sample about 11,500 times the amount of milk expressed to test the components of milk, but with the above conventional method, about 10 times that amount of milk is transferred to the measuring container. Because the remaining milk accumulates in the milk, the device becomes large and the remaining milk has to be returned to the milk pipe, which is a hassle. Therefore, in this invention, from the initial stage to the final stage of milking, the amount of milk expressed is 11,500.
The purpose of the present invention is to provide a simple device capable of sampling a certain amount of milk in an am manner, thereby making it possible to easily collect samples from each dairy cow.

Means for Solving a Question - The milk sampler of the present invention is equipped with a container 2 inserted into a milk tube 23, into which the entire amount of milk flowing through the milk tube is fed vertically from below to above. A leading inflow pipe 5 is provided, and an outflow port 13 is opened at the bottom of the container. Above the inflow pipe 5, a ceiling surface 8 with a dispersion cone 7 is provided, which radially disperses the milk flowing in through the inflow pipe 5 in the upper part of the container 2 in the horizontal direction. A receiving pipe 9 is provided on the side of the inflow pipe 5 to allow a part of the horizontally dispersed milk to flow down, and a conical cone 15 is provided below this receiving pipe 9 to disperse the milk flowing down the receiving pipe 9 into a conical shape. let The lower part of the receiving pipe 9 is connected to the bottom of the container 2, and an outlet pipe 16 is opened facing a part of the periphery of the conical cone 15 and connected to the sample bottle attachment port 17.

The sample bottle attachment port 17 is provided with a screw 18 and other fixing means for fixing the sample bottle 19.

Function 1 The inflow pipe 5 of the milk sampler configured as described above is connected to the claw unit 21 side, the outflow port 13 is connected to the tap 24 of the milk pipe 25, and the sample bottle 19 is fixed to its attachment port 17. Ru.

When milking operation is performed in this state, milk is introduced into the container 2 through the inflow pipe 5, a part of the horizontally dispersed milk flows into the receiving pipe 9, and the rest flows from the bottom of the container into the outlet 13. The milk flows through the milk pipe 25. Receiving pipe 9
The amount of milk flowing into the container 2 is approximately 1150 times the amount flowing into the container 2, and this ratio is determined by the opening area of the receiving pipe 9.

The milk that has flowed into the receiving pipe 9 is dispersed into the conical shape, a part of which flows into the outlet pipe 16, and the rest flows to the bottom of the container and flows from the outlet 13 to the milk pipe. The milk flowing into the outlet pipe 16 is 1/1 of the milk flowing into the receiving pipe 9.
This ratio is determined by the opening area of the outlet pipe 16. The milk that has flowed into the outlet tube 16 flows into the sample bottle 19. In the end, the amount of milk flowing into the sample bottle 19 is about 11,500 of the milking amount, and the milk is uniformly sampled from the beginning to the end of milking.

One Embodiment - Figures 1 to 3 show an embodiment of the present invention. 5 is an inflow pipe vertically installed in the center of the container 2; 7 is a conical dispersion cone placed above the inflow pipe 5; It is installed vertically on the ceiling surface 8 of. Reference numeral 9 denotes a receiving pipe having an oval opening provided on the side of the inflow pipe 5, and the receiving pipe is supported by an inverted funnel-shaped support member 10 provided at the lower part of the receiving pipe. 11

When the milking operation is started, the entire amount of expressed milk flows vertically from below to above into the inflow pipe 5 of the milk sampler 1, and is radiated horizontally by the dispersion cone 7 and the ceiling surface 8 above the inflow pipe. be dispersed. A portion of the dispersed milk flows down the receiving pipe 9 and is conically dispersed in the lower cone 15. A part of the cone-dispersed milk is stored in a sample bottle 19 through an outlet pipe 16. The sample amount in this example was approximately 1/350 of the milking amount.

-Effects of the Invention- According to the above-described apparatus of the present invention, it is possible to uniformly collect approximately 11,500 samples of the total amount of milk milked from a dairy cow from the initial stage to the final stage of milking. , Samples can be easily collected to test the quality and components of the milk that is expressed by the vibrine milling force. Furthermore, the device structure is simple and compact, and the device is convenient to handle and requires low equipment costs.
