[0068] The first driving assembly 230 is arranged outside the first box body 110, and the driving end of the first driving assembly 230 is connected with the outer side wall of the first box body 110 and connected with the lifting assembly 210 through the first box body 110, so that the first driving assembly 230 drives the lifting assembly 210 to move. As a driving component, the first driving assembly 230 is arranged outside the first box body 110, which can reduce the contact between the first driving assembly 230 and the material, so that the material does not corrode the first driving assembly 230, reducing the risk of the first driving assembly 230 being contaminated inside, and improving the service life of the material feeding and drying equipment.

[0069] Optionally, the lifting assembly 210 includes a flexible transmission member, and part or all of the flexible transmission member is arranged vertically.

[0070] In the embodiment, part or all of the flexible transmission member is arranged vertically to vertically lift the bag rack 220 and the material bag 140 and deliver the material bag 140 to the corresponding position.

[0071] Exemplarily, the flexible transmission member comprises a transmission wheel 211, a first driven wheel 212 and a flexible belt 213. The transmission wheel 211 is arranged on the inner side wall of the first cabinet 110 and connected with the driving end of the first driving assembly 230. The first driven wheel 212 is arranged on the inner side wall of the first cabinet 110 and spaced apart from the transmission wheel 211. The flexible belt 213 is arranged around the transmission wheel 211 and the first driven wheel 212, and the material rack is connected with the flexible belt 213.

[0072] In the embodiment, the first driven wheel 212 is spaced apart from the transmission wheel 211, and the flexible belt 213 is arranged around the transmission wheel 211 and the first driven wheel 212, so that the transmission wheel 211 and the first driven wheel 212 can define a transmission path of the flexible belt 213. The driving end of the first driving assembly 230 is connected with the transmission wheel 211 to drive the transmission wheel 211 to rotate, and the transmission wheel 211 rotates to drive the flexible belt 213 to move around the transmission wheel 211 and the first driven wheel 212. The flexible belt 213 moves along the transmission path, the material rack is connected with the flexible belt 213, and the flexible belt 213 drives the material rack to move along the transmission path. In addition, the flexible belt 213 is arranged around the transmission wheel 211 and the first driven wheel 212, and the flexible belt 213 can move circularly.

[0073] Optionally, the flexible belt 213 can comprise a synchronous belt, a belt or a chain. The transmission wheel 211 and the first driven wheel 212 are pulley or sprocket structures matched with the flexible belt 213.

The setting height of the upper end surface of the first sub-cabinet 114 is lower than that of the second sub-cabinet 115. The flexible belt 213 located in the first sub-cabinet 114 is driven in the horizontal direction, and the flexible belt 213 located in the second sub-cabinet 115 is driven in the vertical direction.

[0075] The upper end surface of the first sub-cabinet 114 is provided with a feeding opening 111, and the first cabinet door 112 is arranged on the feeding opening 111 and can be opened and closed.

[0076] In this embodiment, the upper end surface of the first sub-box body 114 is arranged at a lower height than the upper end surface of the second sub-box body 115, and the feeding opening 111 is arranged on the first sub-box body 114. Since the upper end surface of the first sub-box body 114 is arranged at a lower height, the operator can more easily place the material bag 140 at the feeding opening 111, thereby reducing the labor intensity and improving the operation convenience of the equipment. At the same time, the openable and closable design of the first box door 112 ensures the sealing of the feeding opening 111, effectively preventing the pollution of the material by the external environment and the leakage of the material.

[0077] The flexible belt 213 located in the first sub-box body 114 is driven in the transverse direction, and the flexible belt 213 located in the second sub-box body 115 is driven in the vertical direction. Through the transverse driving, the material bag 140 can be smoothly conveyed from the feeding opening 111 to the lifting position. Through the vertical driving, the material bag 140 can be lifted to the target height in the second sub-box body 115. The combination of transverse and vertical driving not only improves the space utilization rate inside the equipment, but also realizes the rationalization of the material conveying path and reduces the complexity of the conveying path.

[0078] Optionally, the number of the bag racks 220 is multiple, and the multiple bag racks 220 are connected to the flexible belt 213 in the extension direction of the flexible belt 213. In this way, when the feeding opening 111 is opened once, multiple material bags 140 can be placed on the multiple bag racks 220, and the material bags 140 are stored in the first space through the bag racks 220. The flexible belt 213 can drive the multiple material bags 140 to move to the transfer position in turn, so that the material transfer device 300 transfers the material bag 140 to the material outlet 121, to realize the automatic feeding of the material and the drying equipment, reduce the feeding frequency of the user, and improve the user experience.

[0079] Optionally, as shown in Figure 7 , the first box body 110 is further configured with a first transfer opening 113, and the flexible belt 213 can drive the material belt to the first transfer opening 113.

[0080] Optionally, the upper end surface of the second sub-box body 115 is provided with the first transfer opening 113.

[0081] Optionally, the second box body 120 is connected to the upper end portion of the first box body 110, and the second box body 120 is further provided with a second transfer opening 122 communicating with the second working space, and the second transfer opening 122 communicates with the first transfer opening 113, so that the first working space and the second working space are communicated. The transfer assembly is arranged in the second working space, and the transfer assembly can move to the second transfer opening 122 to transfer the material bag 140 at the first transfer opening 113 to the second transfer opening 122.

[0082] The transfer assembly is arranged in the second workspace, and the second workspace is in communication with the first workspace. When the first bin door 112 seals the material loading opening 111, neither the first workspace nor the second workspace is in communication with the outside. The transfer assembly can keep the material in a dry space environment when transferring the material bag 140 loaded with the material, thereby reducing the possibility of the material absorbing water and becoming hardened during transportation, reducing the water content of the material during drying, and improving the drying efficiency of the material loading and drying equipment.

[0083] Optionally, the number of the first driven wheels 212 is multiple, and the multiple first driven wheels 212 include an inner first driven wheel and an outer first driven wheel. The inner first driven wheel is in transmission connection with the inner side wall of the flexible belt 213, and the outer first driven wheel is in transmission connection with the outer side wall of the flexible belt 213, so that the flexible belt 213 can be driven in the vertical direction and the horizontal direction.

[0084] In this embodiment, the inner first driven wheel is in transmission connection with the inner side wall of the flexible belt 213, and the outer first driven wheel is in transmission connection with the outer side wall of the flexible belt 213, so that the transmission path of the flexible belt 213 can be changed, and the flexible belt 213 can be driven in the horizontal direction, and / or the vertical direction, and / or the inclined direction. In this way, the material rack can be more flexible in adapting to different space layout requirements during lifting.

[0085] In some optional embodiments, as shown in Figure 9 The two ends of the material bag rack 220 are rotatably connected with the two oppositely arranged flexible transmission members, respectively.

[0086] In this embodiment, the two ends of the material bag rack 220 are rotatably connected with the two flexible transmission members, respectively, so that the material bag rack 220 can be doubly supported to disperse the load on the material bag rack 220, reduce the inclination and instability of the material bag rack 220 caused by unilateral transmission, and improve the stability and safety of the material during lifting and conveying.

[0087] Optionally, the material bag 140 includes a handle portion, a neck portion, and a body portion. The handle portion is used for being held by an operator. The neck portion is connected between the handle portion and the body portion. The body portion is used for loading the material.
