AI Technical Summary

Technical Problem

Piston vacuum pumps are easily kicked by cattle and sheep during use, which can cause damage and potentially harm the animals, resulting in a short service life.

Method used

A piston-type vacuum pump device specifically designed for breast pumps was designed. The pump body is suspended and fixed by engaging with the shed support through the inclined No. 1 bracket and the vertical No. 2 bracket, combined with the structure of the flap frame and U-shaped hanger. The suspension height can be adjusted by rotating the groove locking ring to accommodate different heights of cattle and sheep.

Benefits of technology

This effectively prevents cattle and sheep from kicking the pump body, extends the service life of the vacuum pump, prevents injury to cattle and sheep, and is convenient to use and adaptable to the different height requirements of cattle and sheep.
