Abstract

FIELD: agriculture. SUBSTANCE: milking unit has milking pipelines, milk conveying pipeline, washing pipeline, milk dozers with feeding chambers which are communicated with milk pipeline via washing liquid and milk distribution devices. Washing liquid and milk distribution devices have T-pipe, branch separator and three- way valve. Milk pipelines are connected through branch change-over switch with milk receiver-air separator and milk pump. Three-way valve, T-pipe and branch separator are positioned on milk pipelines and connected one with another to provide for controlled flow of washing liquid and insertion of synthetic wad into both branches and into milk conveying pipeline in the process of washing milking unit. EFFECT: increased efficiency and improved sanitary and hygiene of milking unit. 3 cl, 7 dwg

Description

 The invention relates to agriculture, in particular to the mechanization of the process of milking cows.

 Known milking machine with a milk pipe type ADM-8A, manufactured by JSC "Kurganselmash". Its disadvantage is that the branches of the milk line, lowered during milking and raised during the distribution of feed, reduce operational reliability.

 The closest in technical essence to the claimed invention is a milking unit containing stall milking milk pipelines, paired for washing in conjugated branches, transport and washing milk pipelines, milk dispensers, milk collector located on the transition areas between the milking and transport milk pipelines of the washing liquid distribution device (Aut. St. USSR N 1678257, class A 01 J 5/00, 1989).

 The well-known milking unit, in addition to the two main milk pipelines suitable for the milk receiver, has two flushing pipelines, split flow distributors that are removed before milking, and after milking, they are installed at the inlet of the milk pipelines before washing, therefore it has low technological reliability, is difficult to design and operation.

 In addition, it is impossible to remove residues of milk (after milking) and residues of washing liquid (after washing) from the milking and transport milk pipelines with the wad, which leads to significant production losses, because wads can get stuck in dispensers.

 The objective of the invention is to increase technological reliability, simplify the design and operation of the milking unit, which will ensure better washing of the milk line and other elements of the installation, and improve the sanitary conditions of the milk production process.

 This is achieved by the proposed device, which, like the prototype, contains stall milking milk pipelines coupled for washing in conjugated branches, transport and washing milk pipelines, milk dispensers, a milk receiver located at the transition areas between the milking and transport milk pipelines of the washing liquid distribution device.

 Unlike the prototype, in the proposed milking unit, the device for distributing the washing liquid is made in the form of three-way taps, tees and separators of the branches of the milking milking pipeline, while the milk pipelines have a branch switch and the tees have a grate at the entrance.

 The significance of the differences of the proposed device can be explained as follows.

 The implementation of the device for the distribution of washing liquid in the form of a three-way valve interconnected, a tee with a grill and a branch separator will allow you to connect both halves (branches) of the milking milk pipelines for the passage of the washing wad, as well as regulate the flow of washing liquid through the dispensers and the transport milk line.

 The invention is illustrated by drawings, where in FIG. 1 shows a milking unit in the "milking" position; in FIG. 2 - the same in the "flushing" position; in FIG. 3 - connection of dispensers to the milk line; in FIG. 4 - section of a tee; in FIG. 5, 6, 7 depict the positions of a three-way valve, respectively, during milking; when removing residual milk from the left branch; when removing residual milk from the right branch.

 The milking unit contains installed along the rows of stalls milking pipelines 1 with devices 2 for connecting the milking machines, a transport milk piping 3, milk dispensers 4 with receiving chambers 5 connected to the milk piping 1 via a tee 6 and a branch separator 7. The metering chambers 8 of the dispensers 4 are connected to the transport milk line 3 by hoses 9. Transport 3 and washing milk line 10 are connected to the milking milk line 1 through three-way cranes 11 having a diameter equal to the diameter of the milk milk lines, and with another the milk pipelines 3 and 10 are connected via a branch switch 12 to the milk collector-air separator 13 and the milk pump 14. The receiving chambers 5, the milk collector-air separator 13 are connected via pipes 15 to the vacuum wire 16. The milking unit includes a washing device 17, which is connected via a flexible hose 18 can be connected to the branch pipe 19 of the branch switch 12. At the inlet of the tee 6 there is a grill 20 that prevents the foam wad (not shown) from entering the dispensers 4 during the washing process. The separator 7 of the right and left branches of the milk line is made in the form of a rectangular case with a cylindrical hole, a diameter equal to the diameter of the milk line, and a valve 21 installed in it with the same hole for regulating the flow of washing liquid as the valve moves inside the case.

 Milking installation works as follows.

 Before milking, the branch switch 12 is set to the milking position of FIG. 1, the branch separator 7 is opened, the three-tap valve 11 is set to the position of FIG. 5. Milk from the milking machines through the device 2 enters the milking milk lines 1, of which to the dispensers 4, which lift it through the hoses 9 to the transport milk line 3, from where it enters through the branch switch 12 into the milk collector-air separator 13, from which the milk pump 14 fed to the primary processing (filtration, cooling) and into the tank for storage or shipment.

 Before flushing, the switch 12 is set to the flushing position (FIG. 2), and the three-way valves 11 are in the position shown in FIG. 6. A foam rubber wad is passed into the nozzle 19 of the switch 12 and the remaining milk is displaced from the left branch of the milking milk line into the milk collector-air separator 13. Next, three-way valves 11 are installed in the position of FIG. 7, skip the foam rubber wad and displace the remaining milk from the right branch of the milking milk pipelines into the milk collector-air separator. The flushing device 17 is connected to the branch pipe 19 of the branch switch 12 (FIG. 2), three-way valves are set to the position of FIG. 5, connect the milking machines to the washing device and circulate all the milk paths of the milking machine. The amount of washing liquid flow through the dispensers 4 is controlled by the opening value of the branch dividers 7.
