Description

A hand-push ground chicken manure cleaning machine

Technical Field

The utility model relates to the technical field of ground chicken manure cleaning, in particular to a hand-push ground chicken manure cleaning machine.

Background Art

Raising chickens is an important part of agricultural breeding. It is a production behavior of chickens and eggs by using the physiological functions of chickens, artificially raising and breeding them, so that they can convert plant feed into animal energy. The chicken house refers to the land where chickens live. Chicken manure is a relatively high-quality organic fertilizer, so the chicken manure on the floor of the chicken house needs to be cleaned and collected to make the floor of the chicken house clean.
