Description

The invention relates to agriculture, in particular to devices for washing milking installations of an automated type.

To maintain the required sanitary and hygienic condition of milking machines, they are equipped with collector-type washing stands with a set water flow rate and an autonomous operating mode [1]. The disadvantage of existing system images is the high cost of detergents, the duration of the circulating washing process and significant energy costs.

The closest technical solution (prototype) to the present invention is a device for washing the teat tubes of teatcups, consisting of a base with a supply of washing liquid, to which the teatcups for washing are connected, having four rotating cone-shaped heads with different protrusions on the outside [2]. The disadvantage of this washing scheme is the significant consumption of washing liquid due to the centralized supply and the use of an additional system to drive the washing heads.

The objective of the invention is to improve the quality of washing by increasing the intensity of the hydromechanical effects on the inner walls of the nipple rubber while reducing time, water and washing liquid.

The stand for washing milking cups includes a platform with an internal cavity for supplying detergent with eccentrically mounted collector nozzles for rotation of the milking cups with locking devices for their tight fastening and a drive mechanism. In the device, the collector nozzles are made conical with a mechanically active surface. On the working surface of nozzles for supplying washing liquid to the inner walls of the nipple rubber, spray nozzles are distributed. An additional frictional effect is determined by the presence on the outer surface of the nozzles of a brush part rotating with eccentricity with a differentiated bristle size increasing towards the top of the cone - minimum in the upper part and maximum in the lower. The drive mechanism of the collector nozzles is made in the form of a vacuum drive with a pulsating mode of operation and a crank gear.

The device is illustrated by drawings:

in FIG. 1 shows a stand for washing milking cups, a General view in section;

in FIG. 2 - section AA of the conical surface with distributed spray nozzles.

The stand for washing milking cups includes a platform 1 with an internal cavity 2 for supplying washing liquid, connected by means of a pipe 3 to the supply system of the washing solution. On the surface of the platform 1, four collectors 4 are installed for connecting the teat cups and clamps 5 (locking devices) for tightly mounting the teat cups. The hollow axis of the drive shafts 6 of the collector nozzles 7 are made with spray nozzles 8 dispersed over the conical surface for uniform, volumetric delivery of washing liquid to the contaminated surface of the nipple rubber.

The collector nozzles 7 are made eccentrically relative to the longitudinal axes of the teatcups, while the mechanically active surface of the cones is made in the form of brushes 9 with a differentiated bristle size increasing towards the top of the cone, i.e. minimum in the upper part and maximum in the lower, which contributes to the friction washing and determines the uniformity of the washing effect over the entire inner surface of the nipple rubber.

The collectors 4 on the platform 1 are located similarly to the nipples on the udder of the animal, as a result of which the milking machines are not disassembled, and the milk hoses 10 and the collector of the milking machine 11 are washed at the same time using the CIP.

The general drive of the collector nozzles 7 is made using a crank mechanism 12 from the vacuum created by the vacuum pump of the milking unit by means of a power pneumatic cylinder 13 and a control pulsator 14.

Milking cups 15, located on the rotating collector nozzles 7, driven into rotational motion by means of hollow drive shafts 6 with channels 16 located inside, are washed from the inside of the nipple rubber 17.

The device operates as follows.

When washing an automated milking machine, the milking machine is fixed on the platform 1 located in each milking machine. Milking cups 15 for supplying washing liquid through drive shafts 6 with channels 16 located inside to the inner walls of the nipple rubber 17 are placed on the collector nozzles 7 and fixed using clamps 5.

By changing the position of the tap (not shown), washing liquid is supplied into the internal cavity 2 of the stand using the system vacuum as a driving force, the liquid enters the cavity of the axes of the drive shafts 16 and is sprayed through the jet nozzles 8 onto the contaminated part of the inner surface of the nipple rubber, from which the washing liquid enters the milk hoses 10, then the collector 11, then entering the storage tank (not shown), is used for a further washing cycle of the entire system, hydromechanical effect when synchronization is activated It is compatible with the operation of the washing unit.

Eccentrically rotating relative to the milking cups collector nozzles 7 provide a different supply torch of the liquid jets to the surface of the nipple rubber, and the brush part due to rotation has an intensive frictional washing effect on the surface.

Findings. When using the proposed stand, the quality of washing the milking cups is increased, and the washing time is also reduced. In addition, the device will reduce the amount of water and flushing fluid.
