Firstly, sugarcane leaves and sand are transported to a first platform A and thrown off from the bottom of the fan component 101; secondly, in the throwing process, because the weights of the sugarcane, the sugarcane leaves and the sand and stones are different, the sugarcane is separated from the sugarcane leaves and the sand and stones; then the sugarcane falls down, and sugarcane leaves and sand and stones are sucked up by the axial flow fan 101b and enter the material gathering part 102; finally, the sugarcane leaves and the sand and stones are separated through the filtering of the gathering part 102, the sand and stones are discharged from the gathering part 102, and the sugarcane leaves enter the packing part 104 from the pipeline part 103.

Example 2

Referring to fig. 4 to 6, in a second embodiment of the present invention, which is based on the previous embodiment, the leveling and separating step includes a feeding assembly 200, a conveying assembly 300 and a vibrating screen assembly 400 in sequence.

The feeding assembly 200 is connected to the first platform a through the conveying assembly 300, the conveying assembly 300 is in an ascending conveying arrangement and may be a conventional conveyor belt structure, the casing 101a is erected on the first platform a, and an opening communicated with the bottom is arranged on the first platform a, and the opening at the bottom of the casing 101a is aligned with and directly below the first platform a. The vibrating screen assembly 400 is installed at the bottom of the first platform a and corresponds to the bottom opening of the casing 101 a.

Further, the feeding assembly 200 comprises a storage machine 201, a planar feeding conveyer belt 202 is arranged inside the storage machine 201, and leveling rollers 203 are connected between two side walls inside the storage machine 201; when the system works, firstly, the sugarcane material transport vehicle is driven to the discharging platform to discharge, the sugarcane is dumped on the feeding assembly 200, the feeding assembly 200 is responsible for transporting the sugarcane to the conveying assembly 300 on a plane, and the conveying assembly 300 is responsible for transporting the sugarcane to a high place; the cane is deposited on the infeed assembly 200 and the flattening rollers 203 are responsible for flattening the cane during transport for orderly transport from the conveyor assembly 300 to the first platform a.

The detailed process is as follows: the accumulated sugarcane is leveled by the leveling rollers 203 of the feeding assembly 200 and then is conveyed to the first platform A through the conveying assembly 300, and is parabolically dropped from the first platform A into the vibrating screen assembly 400 arranged at the bottom of the first platform A for first separation.

The vibrating screen assembly 400 comprises a funnel 401, a material guide groove 402 and a vibrating screen 403, the funnel 401 is erected on the first platform a and corresponds to a bottom opening of the machine shell 101a, the material guide groove 402 is located at the bottom of the funnel 401, the material guide groove 402 is communicated with the interior of the material guide groove and corresponds to a bottom opening of the funnel 401, and the vibrating screen 403 is located at the bottom of the material guide groove 402.

The sugarcane is transported to the first platform A from the conveying assembly 300 and falls into the guide chute 402 from the opening of the hopper 401 in a parabolic track, staggered connecting rods can be arranged in the guide chute 402, the sugarcane falls through large grains of sand and stones in the guide chute 402, light micro grains and sugarcane leaves are sucked up by the axial flow fan 101b in the casing 101a, and are blown into the material gathering part 102 by the axial flow fan 101b after passing through the axial flow fan 101 b.

The outer wall of the polymer component 102 is provided with small holes 102c which are uniformly distributed, the polymer component 102 comprises a first port 102a and a second port 102b, the first port 102a and the second port 102b are communicated in a penetrating manner, the diameter of the first port 102a is gradually increased towards the diameter of the second port 102b, the second port 102b is connected with the fan component 101, and the first port 102a is connected with the pipeline component 103.

Because the gathering part 102 has a large opening at one end and a small opening at the other end, the outer wall of the gathering part 102 is inclined inward, when the wind of the axial flow fan 101b blows the first port 102a from the second port 102b, part of the wind blows out from the small holes 102c on the outer wall of the gathering part 102, and blows out together with the light particles, and part of the wind blows the sugarcane leaves and enters the packing part 104.

Meanwhile, the baling unit 104 includes a centrifugal fan 104a and a settling tank 104B, the centrifugal fan 104a is installed on the settling tank 104B and is communicated with the interior of the settling tank 104B, the settling tank 104B is erected on the second platform B, the pipe unit 103 is communicated with the interior of the settling tank 104B, the centrifugal fan 104a is driven to suck the sugarcane leaves into the baling unit 104, and then the sugarcane leaves are baled and taken away from a truck which is settled to the bottom in the settling tank 104B.

The axial flow fan 101b can generate super strong suction force, so that dry dust, small stones and sugarcane leaves can be easily sucked away, and wet soil, heavy stones and a few sugarcane leaves can fall into the vibrating screen 403 for continuous screening; after the axial flow fan 101b sucks impurities through the fan blades, the suction force is changed into thrust force, the impurities are blown into the material gathering part 102, the axial flow fan 101b mainly comprises a shell, a driving motor, a rotary connecting shaft and the fan blades, the driving motor drives the rotary connecting shaft, and the rotary connecting shaft drives the fan blades to rotate to generate the suction force. The impurities may temporarily stay in the polymer member 102. Part of the loose soil dust can be blown out through the small holes 102c on the gathering member 102, and the sugarcane leaves cannot be discharged.

The aggregate part 102 serves to discharge and intake air at the same time, and one is to discharge the large wind generated by the axial flow fan 101 b. If the axial flow fan 101b is directly connected to the settling chamber, the sugarcane leaves cannot settle in the settling chamber due to the overlarge wind speed. When the wind generated by the axial flow fan 101b passes through the material gathering part 102, most of the wind blows out along the mesh, and the rest wind continues to flow to the pipeline to push the sugarcane leaves to flow to the pipeline together, and finally enters the settling tank 104 b. The tapered design of the polymeric component 102 facilitates wind shedding and object flow guidance. The pipe member 103 mainly guides impurities such as wind and sugarcane leaves to the settling tank 104 b. A centrifugal fan 104a with small power is arranged on the settling tank 104b, and the air intake of the centrifugal fan 104a is partly from the air which enters the pipeline part 103 by the axial flow fan 101b, and partly from the air which is pumped from the meshes of the aggregate part 102. The centrifugal fan 104a will suck the sugarcane leaves in the gathering part 102 into the pipe part 103, and this suction is weaker than the wind power of the axial flow fan 101b, and the weaker wind power will not affect the sedimentation of the sugarcane leaves in the sedimentation box 104b while satisfying the requirement of sucking the sugarcane leaves.
