MILK PUMP Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention relates to pneumatic drives of automatic machines for mechanization and automatic of production processes. Proposed pump consists of pressure and vacuum pups, both secured on support plate by means of two posts. Upper wall connects both pumps from top. Pressure and vacuum pumps are provided with lower walls from bottom. Said walls of pumps arranged over perimeter are made of corrugated elastic material. Pressure pump is provided with branch pipe in its lower wall. Measuring stocks are secured to lower walls of pressure and vacuum pumps from side. Said sticks freely get by their middle part into clamps secured to upper wall. Stops with catches are fitted on top of measuring sticks. Capacity or reservoirs both of pressure and vacuum pumps is set by measuring stick and stop. Upper wall is hinge-connected to posts 5 by means of axle. Upper spring is fitted on axle. One end of spring thrust against post, and the other, against upper wall to turn it clockwise. Posts in middle part are connected by bridge on which lower spring is installed. Said spring presses lower walls of pressure and vacuum pumps to their bottoms. Lower walls are moved off by spring from upper wall to stop on measuring stick. Check valve is installed in upper wall at vacuum pump to discharge air from pump space. Vacuum pump branch pipe is secured near. Pressure gauge is installed on upper wall in its middle part to measure pressure and vacuum. Upper wall of pressure pump terminates in pedal. For mechanical milking by pump, mounting place for solenoid motor is provided.

EFFECT: reduced labor input at milking at pasture keeping of cattle and in farms, milking by pedals.
