Abstract

This invention relates to the field of agriculture. The aim of the invention is to increase operational reliability. The position transducer with an automatic manipulator is made in the form of a two-link with a pivot probe 2 and a thrust 3, each of which is connected to springs 7 and 8 connected to the disk 1. The disc is pivotally connected to the thrust, and the stopper 4 and the spring 8 is installed on the disk from the side of the nozzle 5 and the valve 6. The nozzle and the valve are provided with a stop 12 and a spring 10 installed between the disk bracket 14 and the stop. The converter at the beginning of the udder treatment process ensures that the nozzle 5 overlaps the flap 6 with an asymmetrical arrangement of the cow's hind legs and accurate installation of the washing element under the udder. 1 hp f-ly, 4 ill.

Description

BACKGROUND OF THE INVENTION The invention relates to the automation of processes for the predile sanitization of an udder of cows.

The purpose of the invention is to increase operational reliability.

Fig. 1 shows a functional diagram of a converter, where PBy is the output signal associated with the automatic manipulator signal storage unit, and the angle between the vertical axis and the pneumatic contact nozzle; Fig. 2 is a diagram of the arrangement of an elastic cleaning element mounted on a position transmitter; Fig. 3 is a diagram of the node of interaction between the probe and the flap; 4 is a block diagram of a manipulator.

The converter includes a disk 1. on which the probe is installed 2, tons ha 3, limiter 4, nozzle 5, damper b, springs 7-10, stops 11 and 12 and brackets 13 and 14.

T ha 3 with its ends is hingedly connected with the probe and with the disk to form a two-link. A spring of 8 tons and a stop 4 are located on the disk 1 on the side of the nozzle 5 and the valve 6. A spring 10 is installed between the disk bracket 14 and the stop 12.

The manipulator for the predogging sanitary treatment of the udder contains a pneumatic cylinder 15 connected to the rack 16, front and rear clamps 17 and 18 with pneumatic cylinders 19 and 20, the cow appearance detection converter 21, mounted on VI VJ ate

Another washing element 22 placed on the disk 1. A vertical pneumatic cylinder 23, the stem of which is connected to the latch 24, converters 25 and 26 of the position of the elastic cleaning element 22 in the horizontal and vertical planes, elastic bellows 27 associated with the disk 1, horizontal pneumatic cylinder 28 with rod 29 connected to the rack 30, horizontal pneumatic cylinder 31, spray liquid 32 washing fluid, air distributors 33 and 34, switching unit 35, 1st logic unit 36, 2nd logic unit 37, relay 38 for udder sanitation cycle time , block 39 pack the latch 24, the block 40 of storing the signals of the transducers 25 and 26 of the position of the elastic cleaning element 22 in the horizontal and vertical planes, the element 41 YES, the square pulse generator 42, the inversion unit 43, the BAN element 44, the power amplifier 45 connected to generator 42, which in turn is associated with a pneumatic element 44 BAN, block 46 of the combined supply of washing fluid and warm air, relay 47 of the cycle time for washing and cleaning and 3rd logic unit 48.

A position transducer with an automatic manipulator for pre-dredging udder sanitization works as follows.

After the cow is released into the robotized machine, the cow’s registration detection transducer 21 is triggered. rear clamps 17 and 18 (figure 4). Then the process of finding the udder begins with an elastic cleaning element 22, for which the signal from the 1st logic unit 36 enters the working chambers of the pneumatic cylinder 28, on the rod 29 of which the rack 30 rotates the elastic washing element 22 by 90 °, and the pneumatic cylinder 31, which moves it. to the location of the hind limbs of the cow until it touches the probe 2, In contact with one of the two hind limbs of the cow, the probe 2 begins to rotate relative to the rod 3 pivotally connected to it. The other end of the rod 3 is also pivotally connected to the disk 1. Upon further movement, the probe 2 presses the flap 6, which, overcoming the force of the spring 9, closes the nozzle 5. At its output, a single signal appears (Pout 1) which is fed to the unit 40 memorization

signals connected to the relay 47 time cycle of washing and cleaning the udder. Further movement of the elastic cleaning element 22 is stopped, and after a specified period of time, a command is sent from the 1st logical unit 36 to lift the element 22 in a vertical plane using a pneumatic cylinder 23. In this case, the latch 24 is turned off by the signal of the block 39. After the moment of contact the transducer 26 of the position of the elastic cleaning element 22 in the vertical plane with the udder; further lifting stops. The process of washing and cleaning the udder begins, the duration of which is determined by the relay 47 of the cycle time of the washing and cleaning of the udder. In this case, the BANCH element 44, the unit 46 of the combined supply of washing liquid and warm air, and

then a generator 42 of rectangular pulses, a power amplifier 45, an element 41 YES, an inversion unit 43, a 3rd logic unit 48, an air cylinder 15, the rod of which is connected to a rack 16

for reciprocating the elastic cleaning element 22. The supply of warm washing liquid alternates with the periodic supply of the elastic cleaning element 22 to the pump for cleaning by means of elastic

bellows 27 installed above the disk 1,

After the wash cycle time has expired

and cleaning vertical pneumatic cylinder 23

lowers the resilient cleaning element,

air cylinder 28 rotates it 90 °,

and the pneumatic cylinder 31 retracts to the inoperative position upon command of the 2nd logic unit 37. This process is simultaneously accompanied by drying of the udder. With the completion of the sanitation time, the udder opens

front clamps 17, and the cow frees the machine. After its release, the converter 21 for detecting the appearance of a cow generates a signal for closing the front clamps 17 and opening the rear clamps 18. Thus

the machine is prepared for the inlet of the next cow.

Position transmitter with automatic manipulator for pre-dredging of the udder

provides reliable overlapping of the nozzle with the flap when the cow's hind legs are asymmetrical, and especially when the left foot is in front of the neutral axis.
