The invention discloses a labor-saving robot. The labor-saving robot comprises a chopping feeding box, a feeding hopper is arranged at the top face of the chopping feeding box, a downward cavity is formed in the end of the bottom of the feeding hopper in a communicated mode, a downward-extending containing cavity is formed in the bottom of the downward cavity in a communicated mode, the extended end of the bottom of the containing cavity penetrates through the bottom face of the chopping feeding box in a communicated mode, guiding plates are oppositely arranged on the left and right sides of the top of the part, between the downward cavity and the containing cavity, of the containing cavity and extend toward the inner side, a chopping tooth barrel is arranged in the part, below each guiding plate, of the containing cavity, a first converting cavity is formed in the part, on the rear side of each chopping tooth barrel, of the chopping feeding box, a first division plate is arranged between each first converting cavity and the containing cavity, and a front-back extension rotating-winding shaft is fixedly arranged inside each chopping tooth barrel. The labor-saving robot is simple in structure and convenient to operate, reduces the labor capacity, and improves the working efficiency of feeding.
