Description

Device for putting and automatic removal of milking machine from cow's udder

Technical field

The technical solution relates to a device for attaching and automatic removal of the milking apparatus from the cow's udder, which solves the holding of the milking apparatus during preparation, during the actual milking and subsequent removal after the end of the milking and return to the starting position.

BACKGROUND OF THE INVENTION

Some types of parlors are equipped with a device for detecting a milking machine of various designs. The simplest connection is the connection of the milking machine to the vacuum cylinder cable, which withdraws the milking machine and leaves it free to hang after milking. Other devices use a support arm in the form of a hook mounted on a ball pin or telescopic tubes, where the weight of the movable part of the device is balanced by a spring. The disadvantage of these arms is the improper use of the milking machine, which can cause poor milking of the dairy cows. The cow can easily drop the milking machine, which falls to the floor of the stall, sucking up dirt and thereby degrading the quality of the milk. The milker uses only one hand to put on. One hand holds the milking machine by the distributor and the other puts on the teat cups. This design does not make it possible to increase labor productivity. Other milking devices that use support arms for sensing are relatively complex, with pressurized air being used for withdrawal, which makes the system relatively complex and costly. Operation has shown that these devices are not technically perfect, requiring various modifications to make them functionally more reliable and easier to operate. The cost of these devices is quite high.

The essence of the technical solution

These drawbacks are largely eliminated by a device for attaching and automatically removing a milking machine from a cow's udder, consisting of a piston control cylinder, from a sliding tube on a standstill column, with a folding arm attached to the lower end of the tube, the piston of the actuating cylinder, the essence of which is that the base plate is mounted on the impression column. A control cylinder with an internal piston with a pulley for the pulling cable is seated on the base plate. The inner space of the control cylinder is connected to the milking pressure system. Further, the guide plates with plate are mounted on the base plate, in which a tube is slidably mounted, on the upper end of which the end of the cable is fixed and an adjustable stop is placed. At the same time, the cable is guided through the upper pulley, which is seated on the base plate, to the upper end of the weight slidingly mounted inside the tube. A support plate is fastened to the lower part of the pipe and connected by a screw to the first part with the lifting eye. A folding arm with a pulling cable is rotatably mounted in the pivot eye via a set screw. Between the support plate and the first part, a spring is mounted on the pins and a stop on the opposite side. The folding arm consists of at least two parts, connected to each other in a pivotable manner via pins and sliding bearings with stops. The outer part is adapted for the suspension ring, hinge and fastening of one end of the cable. At the same time, in other parts of the folding arm, a draw-through with second pulleys is provided for the pulling cable, which is guided over the guide pulley to the pulley of the inner piston of the control cylinder and fixedly fixed to the bottom of the control cylinder. A protective cover is placed on the base plate.

The device for attaching and automatically removing the milking machine from the cow's udder allows for quick deployment of the Magpie sleeves with both operator's hands. This increases performance in the number of milked cows, prevents the milking machine from falling on the floor and thus sucking dirt into the milk. A further advantage lies in the insertion and removal of the milking apparatus in the direction of the physiological growth of the cow's udder and the arrangement of the arms on the longitudinal axis of the cow does not allow the milking apparatus to tilt. The weight of the moving part of the machine is balanced so that the operator can easily adjust the milking unit height to the cow's udder height.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution is illustrated in the drawings, in which Fig. 1 is a schematic view of the device for inserting and automatically detecting the milking apparatus, Fig. 2 is a plan view of the device with an exploded deployment and milking arm, and Fig. 3 is a plan view of composite device after milking.

Exemplary embodiment

According to FIG. 1, the device consists in that a base plate 1 with guides 5 is mounted on the impression column 4. The guide cylinder 25 with an internal piston 26 with a pulley for a pulling cable 27 is mounted on the guides 5. guides 5 with a plate 6, in which a tube 7 is slidably mounted, on the upper end of which the end of the cable 8 is fixed and an adjustable stop 9. The cable 8 is guided over the first roller 10 seated on the base plate 1 The support plate 12 is fastened to the lower part of the tube 7 by means of a screw 13 to the first part 14 with the eyelet 19, into which the pivot 20 is rotatably seated over the adjusting screw 32 with the folding arm 15 with the cable 27. 12 and the first part 14, the spring 17 is mounted on the pins 16, in this case a rubber, and on the opposite side a stop 18. The folding arm 15 is formed by at least two parts 15a, 15c, rotatably connected to each other via pins 20 and sliding bearings 21 with stops 31. The end portion 15c is provided for the hinge ring 30, hinge 22 and fastening of one end of the cable 27 and at the same time The pulling cable 27 is guided over a guide pulley 29 mounted on the tube 7 to the inner piston pulley 26 of the control cylinder 25 and fixedly attached to the bottom 28 of the control cylinder 25. A protective cover 33 is fitted to the base plate 1.

The device works as follows. Since the last milking, the device has been folded according to FIG. 3 and by the pressure in the actuating cylinder 25 the tube 7 including the folding arm 15 is held in the upper position of the base plate 1. After starting the pushbutton. The pulley 26 with the pulling rope 27 is pushed under its own weight into the lower position of the control cylinder 25, thereby releasing the pulling rope 27. The operator unfolds the folding arm 15 and adjusts it to a height position according to the cow's udder height. The middle portion 15b and the extreme portion 15c of the folding arm 15 are adjusted to the longitudinal axis of the cow, thereby preventing accidental tipping of the milking apparatus. The operator adjusts the minimum height of the folding arm 15 by means of the adjustable stop 9 so that the teat sleeve heads do not touch the standing floor in the rest position. The weight H balances the weight of the folding arm 15. The operator can easily start the milking machine to a different height and horizontal position by grasping the teat shells with both hands and putting them on the cow's udder. The parts 15a, 15b, 15c of the folding arm 15 are provided with stops 31. As a result, the folding arm 15 cannot be disassembled into a so-called dead position. A rubber spring 17 prevents accidental kicking in the folding arm 15 and its subsequent deformation. The folding arm 15 is adjusted to a horizontal position by means of the adjusting screw 32. The hoses of the milking machine must be inserted into the hinge 22, whereby the milking machine distributor is situated in a vertical position. Upon completion of milking, the automation provides an impulse to inject pressure into the actuating cylinder 25. The pressure acts on the pulley 26 with the pulley, moving to the upper position, thereby carrying the pulling cable 27 and the parts 15a, 15b. 15c of the folding arm 15 are folded to the position shown in FIG. 3. The milking machine is then pulled out of the cow's udder and moved to the upper position shown in FIG. 1. In this position, the operator is free to prepare another cow for milking.

Industrial applicability

The device for automatic removal of the milking device from the cow's udder can be used for new milking devices as well as for existing milking systems.
