5. An automatic lifting and pushing device for slaughtering equipment according to claim 1, characterized in that the side wall of the rear end of the cross beam (10) is provided with a plurality of connecting rods (12), the upper ends of the connecting rods (12) are fixedly connected with the cross beam (10), and the lower ends of the connecting rods are fixedly connected with a stop lever (50).

6. A pushing method using the automatic lifting pushing device according to any one of claims 1 to 5, comprising the steps of:

S1: the automatic line pushes the pulley (22) to slide rightwards from a station to be split of the sliding rail (20), a hook (23) at the lower end of the pulley (22) is hung with a pig carcass to be cut, when the pulley (22) slides rightwards and is abutted against the left side of the push head (44), the push head (44) rotates rightwards, the pulley (22) passes through the position of the push head (44), and the push head (44) automatically resets under the action of a reset spring (45);

S2: when the pulley (22) slides to the left side of the self-lowering groove (21), the front side and the rear side of the pulley (22) are in abutting connection with the supporting plate (34), and as the pulley (22) slides towards the self-lowering groove (211), the supporting plate (34) moves downwards under the influence of the gravity of the pig carcass, and the pressure of the lifting cylinder (31) in the process is set at 90 Kpa-120 Kpa;

s3: until the pulley (22) slides to the bottom of the self-lowering groove (21) and is clamped by the self-lowering groove (21), at the moment, the supporting plate (34) is positioned at the set lowest position, the lifting cylinder (31) transmits the signal to the controller (11), the controller (11) transmits the signal to the splitting machine positioned at the front side of the self-lowering groove (21), the splitting machine obtains the signal to start splitting work, and at the moment, the pulley (22) is positioned at the splitting station of the sliding rail (20);

S4: after splitting of the splitting machine is completed, a signal is transmitted to the controller (11), the controller (11) controls the lifting air cylinder (31) to start, the lifting air cylinder (31) drives the supporting plate (34) to move upwards, the supporting plate (34) supports the pulley (22) to move upwards, when the supporting plate (34) is flush with the upper end face of the sliding rail (20), the lifting air cylinder (31) pauses to work, and the pressure of the lifting air cylinder (31) in the process is set at 550-650 Kpa;

s5: the controller (11) controls the translation air cylinder (41) to start, the translation air cylinder (41) drives the push plate (43) to move rightwards, and the push plate

(43) The pushing head (44) is driven to move, the pushing head (44) pushes the pulley (22) to slide rightwards, the pulley (22) falls onto the sliding rail (20) and continues to push the pulley (22) to move until the second sensor (49) detects the baffle (431) on the pushing plate (43), when the pulley (22) reaches the pushing station of the sliding rail (20), the translation cylinder (41) drives the pushing plate (43) to reversely reset until the first sensor (48) detects the baffle (431) on the pushing plate (43), at this time, the pressure of the lifting cylinder (31) is restored to 90 Kpa-120 Kpa, and the pulley (22) reaching the pushing position is pushed rightwards by the automatic line to the next process;

S6: and repeating the steps S1 to S5 to realize automatic lifting and pushing of the pig carcass after splitting.
