Description

Technical field

The present invention relates to a device for attaching and automatically removing the milking apparatus from cow dows, 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 tilt the milking machine, which falls to the floor of the stall, sucking up dirt and thus 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 places 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, and pressurized air is used to withdraw, making 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.

SUMMARY OF THE INVENTION

The above mentioned drawbacks are largely eliminated by a device for attaching and automatically removing a milking apparatus from a cow's udder according to the present invention, comprising a piston control cylinder, from a sliding tube on a parlor column, with a collapsible arm attached to the lower end of the tube. a pulling cable with a piston of the actuating cylinder, the essence of which is that the base plate is fixed to the parlor 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 cable end 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, 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 a 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 apparatus from the cow's udder, according to the invention, enables quick teat sleeves with both hands of the operator. 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 movable part of the machine is designed so that the operator can easily adjust the milking machine height according to the cow's udder height.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a device for attaching and automatically detecting a milking apparatus; FIG. 2 is a plan view of the deployed and milking arm of the device; after milking.

DETAILED DESCRIPTION OF THE INVENTION

According to FIG. 1, the device consists in that a base plate 1 is mounted on the milking column 4, on which the actuating cylinder 25 with the internal piston 26 with the pulley for the pulling cable 27 is connected, connected to the milking pressure system shown. Furthermore, on the base plate 1 are fixed guides 5 with a plate 6, in which a tube 7 is slidably mounted, at the upper end of which the end of the cable 8 is fixed and an adjustable stop 9 is placed. A support plate 12 is fastened to the lower part of the tube 7 by means of a screw 13 connected to the first part 14 with the eyelet 19, into which the pivot 20 is rotatably seated over the adjusting screw 32 with a folding arm 15 with a retractable A spring 17, in this case rubber, is mounted between the support plate 12 and the first part 14, 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 the pins 20 and sliding bearings 21 with stops 31. The end portion 15c is provided for the suspension ring 30, the hinge 22 and the fastening of one end of the cable 27 and at the same time In the other parts 15a of the folding arm 15, a dowel is formed with second pulleys 23 for the pulling cable 27. The pulling cable 27 is guided over the guide pulley 29 to the inner piston pulley 26 of the control cylinder 25 and fixedly to the bottom of the control cylinder 25. the protective cover 33 is fitted.

The device works as follows. Since the last milking, the device has been folded according to FIG. 3 and by applying pressure in the control 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 aligned along the longitudinal axis of the cow, thereby avoiding accidental kicking 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 11 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 into the folding arm 15 and its subsequent deformation. The folding arm 15 is adjusted to the horizontal position by means of the adjusting screw 32. The milking machine hoses must be inserted into the hinge 22, whereby the milking machine distributor is positioned in a vertical position. Upon completion of the connection, the automatics will give an impulse to release the 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 3. In this way, the milking apparatus is removed from the cow's udder and moved to the upper position according to Fig. 1. In this position, the operator's space is free to prepare the next cow for milking.

Industrial applicability

The device for automatic removal of the milking unit from cow dows can be used for new milking systems as well as for existing milking systems.
