Abstract
The utility model relates to a large-sized milking parlour electronic pulsator controller, which consists of a micro processor (1), a driver (2), a thyristor switch (3) and a power-supply circuit (4), wherein, the power-supply circuit (4) is respectively connected with the micro processor (1), the driver (2) and the thyristor switch (3); the micro processor (1) controls the connection and disconnection of the circuit of the thyristor switch (3) through the driver (2); and the driver (2) is connected with the micro processor (1) and the circuit of the thyristor switch (3) so as to trigger the thyristor switch (3). The controller has simple circuit, low malfunction rate, convenient maintenance and low price; the frequency of the controller can be continuously adjusted from 20 times/minute to 120 times/minute, so that the user can select the appropriate frequency.
Description
Technical field
The utility model relates to a kind of large-scale milking parlour electronic pulsator controller, and this controller is used for the mechanization milking equipment.
Background technology
In the mechanization milking equipment, pulsator is the vacuum that opens or closes off and in the milk cup pulsation chamber, makes the milk cup pulsation chamber between milk cup liner and cup form vacuum or atmospheric pressure, alternately finishes and milks and the rest beat.At present, the pulsator that is used for the milking equipment system is divided into two kinds of pneumatic pulsator and electronic pulsators according to the control mode difference.Existing electronic pulsator controller in use has the following disadvantages: (1) electronic pulsator controller and the conjuncted braking of pump housing control cabinet, preparing (taking out negative pressure), finishing electronic pulsator action still in (cleaning glass recorder jar and pipeline) process, so not only produced electric energy loss but also produced electronic pulsator and the wearing and tearing of milk lining, cleaning quality is difficult to improve; (2) power is little, and load capacity is poor, and control voltage drops step by step; (3) complex circuit, the fault rate height, inconvenient maintenance costs an arm and a leg; (4) frequency is single, can not adjust flexibly according to user's request; (5) no self-checking function.
Summary of the invention
The purpose of this utility model provides simple, the frequency adjustable, cheap of a kind of circuit, both can reduce electric energy loss, reduces the large-scale milking parlour electronic pulsator controller of pulsator and the wearing and tearing of milk lining again.
Implementation procedure of the present utility model is as follows:
A kind of large-scale milking parlour electronic pulsator controller, form by microprocessor (1), driver (2), thyristor switch (3) and power circuit (4), power circuit (4) is connected with microprocessor (1), driver (2) and thyristor switch (3) respectively, and microprocessor (1) is by the conducting and the shutoff of driver (2) control thyristor switch (3); Driver (2) connects microprocessor (1) and thyristor switch (3) circuit, triggers thyristor switch (3).
Its operation principle is: power transformer through after step-down, bridge rectifier, the filtering by circuit of three-terminal voltage-stabilizing integrated voltage stabilizing+12V after, for the work of microprocessor (1) and driver (2); It is 20 times/minute～120 times/minute continuously adjustable+12V square waves that microprocessor (1) produces frequency, and this square wave produces forward and reverse square wave by driver (2) back, control thyristor switch (3) circuit; Thyristor switch (3) circuit, is powered behind the bridge rectifier through step-down by transformer, thus the operate as normal of the conducting of IGCT and shutoff control electronic pulsator.
The utility model products panel is provided with three level work status indicator lamps.The first order: power supply indicator, the utility model products panel are provided with band lamp power switch, and the bright expression power supply of switch open indicator lamp is normal.The second level: above power supply indicator, be provided with the microprocessor indicator lamp, as long as microprocessor work is normal, then yellow indicator lamp flicker.The third level: relay indicating light, as long as the thyristor switch circuit working is normal, then red, alternately flicker of green indicating lamp.
Advantage of the present utility model:
A, circuit are simple, and fault rate is low, and is easy to maintenance, cheap.
B, frequency from 20 times/minute～120 times/minute adjustable continuously, the user selects to lock after the suitable frequency according to demand.
C, be provided with self-checking function, can judge the duty of circuit in the controller according to the state of each indicator lamp on the panel rapidly.
D, power are big, and big or small milking station can both be used, and control voltage is steady, makes chopped-off head and final stage almost not have pressure drop.The permission electric current of the supply current of power transformer, bridge rectifier, the permission electric current of IGCT all are far longer than the use electric current, so power is big, can makes the electronic pulsator reliably working and leave the fair work leeway of dividing.
E, electronic pulsator controller and the discrete braking of the pump housing, but like this milk prepare and terminal procedure in the utility model product power cutoff, electronic pulsator is quit work, both reduced electric energy loss, do not produce the wearing and tearing of pulsator and milk lining again, reduce the tolerance loss simultaneously, improved the cleaning quality of glass recorder jar, pipeline and collection breast jar.
