Description

Milking machine

One, technical field

The utility model provides a kind of milking machine, and it belongs to the stockbreeding machine field.

Two, background technology

At present, the milking machine that uses has two big classes both at home and abroad, the fish-bone duct type milking system of a class in the workshop of milking, installing, and mechanization, automaticity height are suitable for large-scale milk cow field boundary and use.Another kind of is portable milking machine, is suitable for milk cow specialist and middle-size and small-size milk cow field boundary and uses.Portable milking machine is divided into vacuum pump type and piston pump formula two classes again.Existing piston pump formula milking machine, its transmission mechanism adopts crank rocker mechanism, and at work, the reciprocating motion of the pistons of piston pump produces vacuum, and simultaneously, the whole pump housing moves back and forth swing again, and moving component is many, and wearing and tearing cause the milking machine cisco unity malfunction easily.The existing piston pump configuration is comparatively complicated, and part is many, and its seal adopts homemade ox-hide bowl, and the ox-hide bowl needs could use behind oil immersion bubble commonly used.In addition, four milk cups of existing milking machine are synchronous operation when work, the physiological requirement of the bovine lactation that is unfavorable for suckling.

Three, the content of utility model

In order to overcome the deficiency of existing portable milking machine transmission mechanism, piston pump structure, and milk synchronously and be unfavorable for suckling the physiological requirement defective of bovine lactation, the utility model provides a kind of milking machine, and it is simple in structure, practical, easy to adjust.Be connected with control valve by pipeline, constitute pipe-line system, utilize the total travel of piston pump, realize four asynchronous milking of milk cup, the breast to milk cow is massaged in the process of milking simultaneously.

This milking machine is made of milk cup, clawpiece, milk churn, check valve, control valve, piping installation, transmission device, transmission device wherein is made of electromotor, belt transmission, reductor, slider-crank mechanism, mechanism is simple, piston pump is made of upper and lower pump cover, piston rod, cylinder body, piston, sealing ring, on piston sealing ring is installed and cylinder body is combined closely.Piston pump is fixed on the frame, during work, does not swing, and is reliable, easy to maintenance.Four milk cups are divided into two groups, and one group of milk cup group is respectively by clawpiece, and the milk guard system is connected in milk churn, and is connected in the upper cavity of piston pump by tracheal system, control valve; Another group milk cup group is connected to milk churn, and is connected in the lower chamber of piston pump by tracheal system, control valve by clawpiece, milk guard system respectively; One group of check valve also is installed on piston pump; By being connected of pipeline and control valve, constitute pipeline, utilize the total travel of piston pump, realizes asynchronous the milking of four milk cups, while breast to milk cow in pushing through journey is massaged.
