By the arrangement, the cleaning spray pipes 250 of corresponding models can be installed according to the actual situation of the lifting device 200, for example, when a large-size driving chain is adopted, the cleaning spray pipes 250 with smaller sizes can be selected to avoid the movement interference of the two; and will not be described in detail herein.

In some embodiments, at least one cleaning nozzle 250 is disposed, at least two sets of the transfer assemblies 240 are disposed, and two sets of the transfer assemblies 240 are disposed on opposite sides of the lift bin 210, respectively, and at least one cleaning nozzle 250 is disposed in each set of the transfer assemblies 240.

In this embodiment, the two opposite sides of the lifting bin 210 are provided with the conveying assemblies 240, so as to ensure the conveying effect of the lifting device 200; by providing at least one cleaning nozzle 250 in each transfer assembly 240, cleaning operations may be performed within the transfer assembly 240, thereby ensuring operational stability of the tobacco conveying apparatus 10 and avoiding growth of tobacco worms within the lifting device 200.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
