Vacuumizing device for milking dairy cows

Abstract

The invention discloses a vacuumizing device for milking dairy cows. The vacuumizing device comprises a first barrel body, wherein a first air pipe is arranged at the barrel bottom of the first barrel body; a first piston plate is slidably connected into the first barrel body; one side of the first piston plate is fixedly connected with a first piston rod; a first push-pull device for controlling the first piston rod to reciprocate is arranged at the outer side of the first barrel body; one side of the first barrel body is fixedly connected with a fixing plate; one side of the fixing plate is fixedly connected with a second barrel body; a second piston plate is slidably connected into the second barrel body; one side of the second piston plate is fixedly connected with a second piston rod; and one end of the second piston rod is provided with a second push-pull device for controlling the second piston rod to do reciprocating motion. The vacuumizing device has the advantages that the vacuumizing device can slowly perform vacuumizing, so that the breasts of a dairy cow gradually adapt to the suction force; and after the dairy cow adapts to the suction force, the suction force can be increased suddenly, and milk of the dairy cow can be fully sucked out.

Description

technical field [0001] The invention relates to the technical field of milking equipment, in particular to a vacuuming device for milking cows. Background technique [0002] During the milking process, atmospheric pressure is formed by the action of vacuum, and suction is formed by the milking cup to extract and collect the milk. The vacuum pumping device for milking cows in the prior art usually adopts a vacuum pump. Milk is usually evacuated directly, the pumping speed is fast, and it directly acts on the nipple of the cow, which is easy to cause damage to the udder of the cow. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose a vacuuming device for milking cows in order to solve the shortcomings in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A vacuum pumping device for milking cows, the vacuum pumping device comprises a first barrel body, a fir...
