[0036] like Figures 1-5 As shown, this utility model provides a discharge and impurity removal device for a sugarcane harvester, which mainly includes a frame 1, a fan 2, a conveying support device 3, a guide plate 4, and a receiving box 5.

[0037] The blower 2 includes a housing 21, a rotating shaft 22, and a rotating blade assembly 23. The housing 21 is fixedly mounted on the frame 1. An air outlet 200 is provided on the housing 21, located next to the discharge port of the peeling and de-tip-removing device of the sugarcane harvester. The air outlet 200 is an elongated strip extending along the length of the sugarcane, and its length is the same as the discharge port of the peeling and de-tip-removing device. This allows for blowing air to remove impurities from the sugarcane over a wide range, ensuring effective and efficient removal. An air inlet is provided in the middle of the housing 21, and a filter screen 8 is fixedly mounted on the air inlet to prevent debris from entering the blower 2 and affecting its normal operation. The rotating shaft 22 is rotatably mounted inside the housing 21. In this embodiment, both ends of the rotating shaft 22 extend out of the housing 21 and are rotatably mounted on the frame 1 via bearing seats. A pulley is fixedly mounted on one end of the rotating shaft 22 for driving the rotating shaft 22 to rotate via a belt. The rotating blade assembly 23 is fixedly mounted on the rotating shaft 22. Specifically, the rotating blade assembly 23 includes a fixed sleeve 231, connecting rods 232, and rotating blades 233. The fixed sleeve 231 is fixedly mounted on the rotating shaft 22. Multiple sets of connecting rods 232 are arranged along the axial direction of the fixed sleeve 231, with each set including multiple connecting rods 232. These multiple connecting rods 232 are arranged circumferentially around the fixed sleeve 231, and one end is fixedly connected to the side wall of the fixed sleeve 231. Multiple rotating blades 233 are arranged circumferentially around the fixed sleeve 231, and the side of each rotating blade 233 is fixedly connected to the other end of a connecting rod 232. The design of the rotating blade assembly 23 is beneficial for improving the uniformity and coverage of airflow and enhances the structural stability.

[0038] In this embodiment, multiple nuts 6 are welded to the side wall of the fixing sleeve 231, and multiple through holes coaxial with the screw holes of the nuts 6 are opened on the side wall of the fixing sleeve 231. A bolt 7 is screwed into the nut 6, and one end of the bolt 7 passes through the through hole and is tightened against the rotating shaft 22. The matching arrangement of the nuts 6, through holes and bolts 7 facilitates fixing the fixing sleeve 231 to the rotating shaft 22, thereby facilitating installation and maintenance.

[0039] The conveying support device 3 is mounted on the frame 1. The conveying support device 3 includes a first conveying component 31 and a second conveying component 32. The first conveying component 31 is located below one end of the blower 2, and the second conveying component 32 is located on the side of the first conveying component 31 away from the blower 2. The first conveying component 31 and the second conveying component 32 are arranged parallel to one end of the blower 2 to support and convey the lower half of the sugarcane, ensuring the stability of the sugarcane conveying. The first conveying assembly 31 includes a first mounting plate 311, a first sprocket 312, and a first chain 313. The first mounting plate 311 is fixedly mounted on the frame 1. There are two first sprockets 312, both rotatably mounted on the first mounting plate 311. The first chain 313 is driven and sleeved on the two first sprockets 312. The top height of the first chain 313 is greater than or equal to the top surface height of the first mounting plate 311 to prevent the first mounting plate 311 from obstructing the conveying of sugarcane by the first chain 313. In this embodiment, the top height of the first chain 313 is equal to the top surface height of the first mounting plate 311, so that the first mounting plate 311 and the first chain 313 jointly support the sugarcane, further ensuring the stability of the sugarcane conveying. The second conveying assembly 32 includes a second mounting plate 321 and a second sprocket 32. 2. The second chain 323 and the second mounting plate 321 are fixedly mounted on the frame 1. There are two second sprockets 322, both of which are rotatably mounted on the second mounting plate 321. The second chain 323 is driven and sleeved on the two second sprockets 322. The top height of the second chain 323 is greater than or equal to the top surface height of the second mounting plate 321 to avoid the second mounting plate 321 from obstructing the second chain 323 from conveying the sugarcane. In this embodiment, the top height of the second chain 323 is equal to the top surface height of the second mounting plate 321, so that the second mounting plate 321 and the second chain 323 jointly support the sugarcane, further ensuring the stability of the sugarcane conveying. The top height of the second chain 323 is equal to the top height of the first chain 313. The second chain 323 and the first chain 313 jointly convey the sugarcane. In this embodiment, the length of the second chain 323 is greater than the length of the first chain 313. Specifically, the end of the first chain 313 near the receiving box 5 is flush with the end of the second chain 323 near the receiving box 5. The other end of the first chain 313 is connected to the discharge port of the leaf-peeling and tip-removing device. The other end of the second chain 323 extends beyond the first chain 313 and is located directly below or beyond the discharge port of the leaf-peeling and tip-removing device. When the sugarcane is discharged from the discharge port of the leaf-peeling and tip-removing device, it is first transported to the end of the first chain 313 through the second chain 323. Then, the first chain 313 and the second chain 323 work together to transport the sugarcane, ensuring that the sugarcane can be smoothly output onto the first chain 313 and the second chain 323.

[0040] Multiple feeding claws 9 are fixedly arranged on the outer surfaces of both the first chain 313 and the second chain 323. The feeding claws 9 on the first chain 313 and the second chain 323 are arranged opposite each other, and the first chain 313 and the second chain 323 rotate at the same speed. Gap spaces for placing sugarcane are provided between adjacent feeding claws 9, and each gap is of the same size. The feeding claws 9 help to restrict the position of the sugarcane during the conveying process, prevent the sugarcane from shifting, and ensure the normal conveying of the sugarcane.

[0041] The guide plate 4 is fixedly installed on the frame 1 and located below the air outlet 200 of the fan 2. The height of the guide plate 4 is lower than the top surface height of the conveying support device 3, and one end of the guide plate 4 is inclined downward in the direction away from the air outlet 200 to guide impurities to fall smoothly.

[0042] The receiving box 5 is fixedly installed on the frame 1 and located at the end of the conveying support device 3 away from the fan 2, and is used to receive sugarcane.

[0043] The specific operating steps of this utility model are as follows:

[0044] When the sugarcane harvester is working, the sugarcane, leaves, and sugar-free tips output from the discharge port of the leaf-removing and tip-removing device enter the working range of this discharge and impurity removal device. Under the action of gravity, the lower part of the sugarcane falls on the second chain 323. The second sprocket 322 drives the second chain 323 to rotate. The feeding claws 9 on the second chain 323 push the sugarcane towards the receiving box 5. When the sugarcane moves to one end of the first chain 313, the first chain 313 and the second chain 323 together convey the sugarcane towards the receiving box 5. During the conveying process, the blower 2 starts, and the rotating blade assembly 23 rotates under the drive of the rotating shaft 22, generating airflow. The airflow is blown out through the elongated air outlet 200. The blown air acts on the output sugarcane, leaves, and sugar-free tips, blowing impurities such as leaves and tips onto the guide plate 4, where they fall downwards under the guidance of the guide plate 4. The clean sugarcane is then conveyed into the receiving box 5.
