In order to further enable the first conveying mechanism 2 and the second conveying mechanism 3 to stably lift, at least two guide mechanisms 7 are arranged, and when the two guide mechanisms 7 are arranged, the two guide mechanisms 7 are respectively arranged at the middle parts of two opposite sides of the base 4. Of course, those skilled in the art can also make other number and position layouts, which are not limited herein.

The conveying rollers 22 and the conveying belt assemblies 32 of the transfer conveying device in the embodiment can convey articles in a first direction and a second direction perpendicular to the first direction respectively, and the conveying belt assemblies 32 are positioned between the adjacent conveying rollers 22, so that the occupied space in a horizontal plane is saved; when the articles are conveyed, the conveying rollers 22 and the conveying belt assemblies 32 can be lifted alternately to convey the articles in the first direction and the second direction respectively, so that the articles can be sorted; the structural arrangement of the first conveying mechanism 2, the second conveying mechanism 3, the lifting mechanism 6 and the base 4 in the embodiment also reduces the height of the transfer conveying device in the embodiment; further, when the first conveying mechanism 2 and the second conveying mechanism 3 are lifted, the gravity of the descending one of the first conveying mechanism 2 and the second conveying mechanism 3 can be converted into the driving force of the ascending one, so that the load of the lifting mechanism 6 can be reduced, the lifting speed of the first conveying mechanism 2 and the second conveying mechanism 3 can be increased, and the transfer efficiency of the articles can be improved.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
