double-down cutter: then the cutting power part (6) is started, the cutting power shaft (12) moves downwards, the fixing plate drives the fixing bracket (15) to further drive the sleeve to move downwards, more than one arc split blades (7) are used for splitting and cutting jackfruit, and the arc split blades (7) can smoothly cut due to the dislocation arrangement of the multipurpose column (82) and the arc split blades (7); meanwhile, the coring bit tube (17) performs coring cutting at the middle part of jackfruit, and as the middle coring port (16) is not shielded by the multipurpose column (82), the coring bit tube (17) can smoothly cut off;

the front support of the retracting tool moves upwards: then the multipurpose motor (19) starts the multipurpose ring (81) to move upwards properly, and the jackfruit is released from being pressed;

retracting and splitting: then the cutting power part (6) is started, the cutting power shaft (12) moves upwards, the cut jackfruit moves upwards, the multipurpose ring (81) and the multipurpose column (82) push the cut jackfruit downwards, and the cut jackfruit falls after being divided into multiple pieces; the cut jackfruit is divided into multiple pieces and then falls down along the arc-shaped surface of the circle contained by the bearing platform (11) in a guiding way, and falls into the conveying frame (2) on the conveying structure (1).

10. The pre-treatment method of jackfruit without extrusion erosion according to claim 9, wherein,

and (3) fixing a shell: dividing the cut jackfruit into multiple pieces, placing the multiple pieces on a basic platform (39), starting an extrusion power part (29) to drive an extrusion shaft (36) to push forward, further driving an extrusion block (37) to extrude forward, and extruding a fixed shell (38) by two symmetrically arranged extrusion blocks;

then the meat taking power part (23) is started downwards, the meat taking power shaft (24) moves downwards to extrude, the spring (25) and the connecting column are downwards extruded together, the arc-shaped cutter head (26) cuts into the contact position of the pulp and the fruit shell, the pulp is soft, the fruit shell is hard, and the pressure exerted by the spring (25) enables the arc-shaped cutter head (26) to be clung to the contact position of the pulp and the fruit shell;

the cutting power motor (41) is started, the cutting power shaft (42) rotates to drive the upper bracket (22) to move leftwards, and the arc-shaped cutter head (26) cuts leftwards along the contact position of pulp and fruit shells due to the existence of pressure applied by the spring (25), so that the separation of the pulp and the fruit shells is realized;

the separated pulp is collected through a lower pulp opening (45), and the shell is collected through a lower shell opening.
