The invention discloses a barrel jacking mechanism of a drum screening machine used for municipal domestic waste treatment. The barrel jacking mechanism comprises four adjustable brackets, four lifting jacks, and front and rear fixed brackets, wherein two adjustable brackets are arranged at the two sides below the front end part of a barrel; two adjustable brackets are arranged at the two sides below the rear end part of the barrel; each adjustable bracket consists of a bottom plate, a supporting plate, two side plates and two lug plates; an adjusting bolt is mounted on each lug plate; the four lifting jacks are arranged below the bottom plates of the four adjustable type brackets one by one; under the action of corresponding lifting jacks, the four adjustable brackets are in a jacking state; the upper end surfaces of the supporting plates are jacked on the outer surface of the barrel, so that the barrel moves upwards to a position which forms a gap with a supporting roller; the two fixed brackets are respectively arranged on positions below the front end part and the rear end part of the barrel; when the four adjustable type brackets are in the jacking state, the upper end surfaces of the two fixed brackets are jacked on the outer surface of the barrel. The barrel jacking mechanism can enable the barrel to lift upwards, so that performance reduction caused by pressing the supporting roller for a long time through the barrel is avoided.
