Essential oil squeezing and preparing device capable of automatically cleaning waste residues and used for processing Chinese herbaceous peony seeds

The invention discloses an essential oil squeezing and preparing device capable of automatically cleaning waste residues and used for peony seed processing, belongs to the technical field of peony seed oil squeezing, and aims at solving the problem that existing squeezing and preparing equipment is high in speed and serious in waste. Paeonia lactiflora seeds are added into a pressing cylinder through a feeding pipe and a feeding hopper, a pressing plate squeezes the peony seeds in the pressing cylinder, squeezed oil liquid is discharged through an oil outlet header pipe, when a linkage rod moves, a pull rope is pulled to drive a locking block to move, and under the reset pulling action of a reset spring, a residue storage cylinder rapidly gets close to a fixing disc; in the approaching process, cakes left after internal Chinese herbaceous peony seeds are squeezed are blocked by the base plate and finally fall down from the slag outlet, then when the pressing plate is reset, the tail end of the sliding rod dri
