The utility model discloses a marching type transfer chain 10 pushes away including carrying and colludes subassembly 100, moving mechanism 200 and transport main part 300, wherein, carries to push away to collude subassembly 100 and connects on moving mechanism 200, and moving mechanism 200 connects on carrying main part 300, and moving mechanism 200 drives to carry to push away to collude subassembly 100 and follow direction of delivery X reciprocating motion on carrying main part 300 to make carry to push away to collude subassembly 100 and drive and treat that the transported substance is along direction of delivery X marching type transportation.

The moving mechanism 200 drives the conveying hook assembly 100 to reciprocate and has a forward stroke and a backward stroke. In the process of moving forward along the conveying direction X by the conveying pushing and hooking component 100 driven by the moving mechanism 200, the conveying pushing and hooking component 100 is located at the pushing position, and the moving mechanism 200 drives the conveying pushing and hooking component 100 to push the material to be conveyed along the conveying direction X, so that the material to be conveyed is conveyed along the conveying direction X. In the return process of the moving mechanism 200 driving the conveying push-hook assembly 100 to retreat along the conveying direction X, firstly, the conveying push-hook assembly 100 rotates from the push-process position to the return-process position due to the obstruction of the material to be conveyed when retreating, and rotates from the return-process position to the push-process position through the action of gravity when the obstruction disappears, so as to prepare for entering the next step-by-step pushing.

The conveying and pushing hook assemblies 100 are multiple and are connected to the moving mechanism 200 at intervals, and each conveying and pushing hook assembly 100 is used for conveying one material to be conveyed, for example.

As shown in fig. 2 to fig. 5, the conveying pushing hook assembly 100 of the present invention includes a mounting base 110 and a pushing hook 120, wherein the mounting base 110 is connected to a moving mechanism 200, and a first limiting structure 130 and a second limiting structure 140 are connected thereto. The push hook 120 is rotatably connected to the mounting base 110 and is disposed obliquely along the conveying direction X, and has a push position limited by the first limiting structure 130 and a return position limited by the second limiting structure 140 during the rotation.
