10. An operation method of a three-row bucket-pushing weighing filling machine structure is characterized in that:

step 1: conveying the filling barrel for one time: firstly, placing a filling barrel on a conveying belt (74), then starting a driving motor I (71), enabling the driving motor I (71) to drive a rotating rod (72) and a driving wheel (73) to rotate, enabling the driving wheel (73) to rotate two conveying belts (74) to start to move oppositely, driving the filling barrel to start to move by the conveying belt (74) with the filling barrel placed at the moment, and closing the driving motor I (71) after gaps between the filling barrel and five weighing devices (91) are formed, so that one-side conveying of the filling barrel is completed;

step 2: once barrel pushing: after the filling barrel is positioned, a second driving motor (81) is started, after a barrel pushing mechanism (8) is started, the second driving motor (81) drives a rotating rod (83) to start rotating, at the moment, a gear (84) on the surface of the rotating rod (83) can rotate along with the rotating rod (83), a chain (85) on the surface of the gear (84) can also rotate when the gear (84) rotates, a push plate (86) can rotate along with the chain (85) when the chain (85) rotates, when the push plate (86) starts to rotate, the push plate (86) can gradually approach the filling barrel, after the push plate (86) is contacted with the filling barrel, the push plate (86) continuously rotates to drive the filling barrel to move towards a weighing device (91), after the filling barrel completely reaches the top of the weighing device (91), the second driving motor (81) is closed, and at the moment, the filling barrel can stop at the top of the weighing device (91), so that one-side barrel pushing is completed;

and step 3: filling: then according to the size of the filling barrel, if the filling barrel is large, the first air cylinder (607) can be started, the first air cylinder (607) drives the connecting block (609), the second filling head (608) and the baffle (610) to move, after the baffle (610) is separated from the discharge block (603), the filling valve (4) is started, materials enter the filling valve (4) through the pumping pipe (5) and then enter the first filling head (601), at the moment, the materials flow downwards through the first through hole (604) and the second through hole (605) in the first filling head (601), so that the filling of a large filling barrel is realized, and the filling barrel is small, the first air cylinder (607) can control the connecting block (609), the second filling head (608), the baffle (610) and the discharge block (603) to contact, so that the materials only flow downwards through the first through hole (604) and the second filling head (608), so that the filling of a small filling barrel is realized, and the filling barrel is positioned behind the top of the weighing device (91), switching a second filling head (608) and a first filling head (601) according to the size of the filling barrel, then starting a second air cylinder (11), enabling the second air cylinder (11) to drive a lifting plate (3), a filling valve (4) and a filling mechanism (6) in the lifting plate (3) to move downwards, starting the filling valve (4) to fill the materials after the filling mechanism (6) is located in the filling barrel, and recovering the second air cylinder (11) until the filling barrel reaches a set weight, so that the filling mechanism (6) is separated from the filling barrel, and filling is completed;

and 4, step 4: and (5) pushing the barrel for the second time: after the filling of the filling barrel is finished, the second driving motor (81) is started again, so that the second driving motor (81) drives the push plate (86) to push the filled filling barrel to move continuously through the matching among the structures until the filled filling barrel is moved to the other conveying belt (74);

and 5: and (3) secondary conveying of the filling barrel: after the filled filling barrel reaches another conveying belt (74), the push plate (86) can continue to rotate until the filling barrel is separated from the through groove (10), then the push plate (86) can continue to rotate to the inside of the conveying belt (74) used for placing the non-filled filling barrel, the barrel is waited to be pushed next time, and after the filled filling barrel reaches the conveying belt (74), the driving motor I (71) is started again, so that the driving motor I (71) drives the filled filling barrel on the conveying belt (74) to move, meanwhile, the non-filled conveying belt (74) is placed, and the empty barrel is continuously conveyed, and therefore three rows of pushing barrels are achieved.
