Description

The invention relates to agriculture, in particular to devices for metering milk when milking cows in dairy farming.

A known milk counter containing milk dampers in the form of cylindrical containers, a counter case with milk volume meters inside, a digital adder for recording the milk yield, all these nodes are fixed to the frame using connecting equipment [Kovalev Yu.N. Dairy equipment for livestock farms and complexes: Reference. - M .: Rosselkhozizdat, 1987, p.21].

The known milk yield counter has disadvantages. When milking, this counter measures the volume of incoming milk, which leads to a significant error due to the different contents of the foam in the milk, and the pressure drop. In addition, the well-known counter is designed to account for milk from a group of cows and is not used to account for individual milk yield of a cow.

A milk milk counter is also known, including a housing with tipping trays and a flow damper in the form of a cylinder with a lid and a supply pipe [A.S. USSR No. 1335210, class A01J 7/00, 1987. "Milk milk counter." declared 04/10/1985, publ. 09/07/1987. Bull. No. 33].

The milk meter works as follows.

During milking, milk enters through the pipe into the damper, from which it is discharged through the inlet pipe into one of the trays, which is under the pipe at this time. When filling the tray with milk, it overturns under the action of the mass, turning around its axis, and under the inlet pipe it becomes the second of the paired trays. The pins rotate the trays. When turning the trays, a permanent magnet acts on a sealed contact, which, when the contacts are closed, gives an impulse to a counting device that takes into account milk yield.

The known milk yield counter has drawbacks: when measuring milk, transients associated with topping a certain portion of milk to its main portion are not taken into account, which reduces the accuracy of determining the amount of milk. Does the tray move from the position it occupies immediately after the next tipping over to the moment when the other half of the tray begins to fill when it is rotated? is a transitional period in which the volume of milk from the tray is not yet poured. During the passage of the tray from one position to another during the transition period, to the main portion of the milk, a portion of the milk is poured into the same half of the tray from the funnel in an amount depending on the speed of rotation of the tray. This part of the milk remains unaccounted for and leads to the formation of an error in the measurement.

Also, due to the design feature of the work (swinging tray), the known meter does not take into account the milk that is lashed through the tray at a very high milk flow rate of the cow, especially during an intensive milk allowance, which also leads to inaccurate measurement of milk milk.

The objective of the invention is to increase the accuracy of accounting for milk yield from each cow.

The technical result consists in increasing the accuracy of determining the amount of milk milk from a specific animal.

The technical result is achieved in that the milk meter containing a milk-type milk damper with a nozzle, a housing with inlet and outlet nozzles, a permanent magnet and a sealed contact connected to the metering device, trays fixed on an axis, and a stop device, and the trays are interconnected the side surfaces that are arranged around the circumference with the formation of the chute wheel, inside the body, two end walls of the chute wheel are made in the form of a hexagon, in which the adjacent adjacent side overhnosti trays are made to form a trough edges wheel which is fixed on the axle for rotation; moreover, in the case of the milk counter there is a thrust device made in the form of a pivotally mounted lever, one end of which is made in the form of a rectangular plate, and the other is the end in the form of a closed tube, concave downward, inside of which a counterweight made in the form of a ball is placed.

The counterweight placed inside the tube is mounted to move when the position of the pivotally mounted lever changes, and a magnet is fixed to the pivotally mounted lever.

Comparative analysis with the prototype shows that the claimed milk meter meets the criterion of “novelty”, as it has significant differences /

1. Trays are interconnected by side surfaces.

2. The side surfaces are located around the circumference with the formation of the trough wheel.

3. Inside the housing, two end walls of the chute wheel are made in the form of a hexagon.

4. The connected adjacent lateral surfaces of the trays are formed with the formation of ribs of the chute wheel.

5. The chute wheel is rotatably mounted on an axis.

6. A thrust device is installed in the milk meter housing.

7. The thrust device is made in the form of a pivotally mounted lever.

8. One end of the lever is made in the form of a rectangular plate, and the other end is in the form of a closed tube concave downward.

9. A counterweight made in the form of a ball is placed inside the tube.

10. The counterweight placed inside the tube is mounted to move when the position of the articulated arm is changed.

11. A magnet is attached to the pivotally mounted lever.

In order to increase the accuracy of the design of the milk meter, the trays are interconnected by lateral surfaces, located around a circle and form a pan wheel. In the prototype, two trays are connected by side surfaces, and in the proposed milk meter, six trays form a tray wheel, which increases the accuracy of the readings.

In order to reduce splashing, the trough wheel is rotatable on an axis.

For the purpose of a fixed rotation of the wheel mounted thrust device.

In order to be able to turn the thrust device, it is made in the form of a lever and is mounted pivotally.

In order to fix the tray wheel, one end of the lever is made in the form of a rectangular plate, and the other end is in the form of a closed tube bent downwards.

In order to allow the lever to deviate and hold the trough wheel at rest, a counterweight in the form of a ball is installed in the concave tube.

In order to calculate the amount of milk milk, a magnet is mounted on the lever.

Identified signs of a technical solution of the proposed milk meter allow us to conclude that the technical solution meets the criterion of "significant differences".

The technical solution is represented by drawing material.

Figure 1 schematically shows the proposed milk meter; figure 2 is a section aa in figure 1; figure 3 - remote element B of figure 2.

The milk meter consists of a cylindrical damper type 1 with a pipe 2, a housing 3 with an inlet pipe 4, which is closed by a frame 5 made of transparent material. Bottom of the housing 3 there is an outlet pipe 6, inside the housing 3 around the circumference are trays 7, interconnected by the side surfaces 8 and forming a trough wheel 9, mounted on the axis 10. The end surfaces of the trough wheel 9 are made by hexagons 11. The rotation of the trough wheel 9 limits the lever 14 pivotally hinged on the axis 12 of the frame 13, which on the one hand is made in the form of a rectangular plate 15, and on the other - in the form of a concave hollow tube 16, closed by a plug 17, with a ball 18 inside. A magnet 19 is attached to the rectangular plate 15 of the lever 14, which acts on the sealed contact 20. When the contact is activated, electrical pulses are supplied to the counting device 21.

The milk meter works as follows. In the initial state, the tray wheel 9 in the housing 3 is at rest, one face rests on the lever 14. When milking, milk from the milking machine enters through the nozzle 2 into the damper 1, from which it then merges into the housing 3 through the inlet pipe 4 and fills one of trays 7 of the chute wheel 9. When a certain mass of milk is reached in the chute 7, the chute wheel 9 has a moment of force acting on the lever 14, under the action of this force, the upper part of the lever, a rectangular plate 15, starts to fall down, and the lower part is concave down tube 16 begins to rise. The counterweight in the form of a ball 18 begins to shift to the center of the lever 14, due to this the center of mass is shifted, the trough wheel 9 is fixedly rotated to the next face. The next tray 7 of the chute wheel 9 is filled with milk. With a fixed rotation of the chute wheel 9 and, therefore, lowering the upper part of the lever 14, the rectangular plate 15, the magnet 19 acts on the sealed contact 20, which when triggered gives an impulse to the counting device 21. Then the process repeated the same way.

The use of the claimed milk meter eliminates unaccounted milk overflow from adjacent sections with intensive milk allowance, which allows to increase the accuracy of milk measurements during milking.
