[0002] Patent application CN 116458334 A discloses a sugarcane harvester, including a vehicle body, left and right straightening devices, front and rear straightening devices, a feeding device, a harvesting device, a lowering device, and a leaf and tip removal device. The lowering device lowers the sugarcane backward around its roots, and the upper part of the lowered sugarcane enters the leaf and tip removal device for subsequent tip removal and leaf removal. However, the lower part of the sugarcane lacks support when lowered, resulting in poor stability and a tendency to tilt or slide, hindering the lowering operation and severely impacting the efficiency and quality of sugarcane harvesting. Therefore, there is an urgent need for a device to assist the sugarcane harvester in lowering sugarcane to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a sugarcane harvester's tipping auxiliary device to solve the problem of sugarcane not being tipped smoothly.

[0004] This utility model is implemented as follows:

[0005] A sugarcane harvester's tipping auxiliary device, for being installed below the sugarcane harvester's tipping mechanism, includes:

[0006] The frame is inclinedly mounted on the body of the sugarcane harvester;

[0015] As a further technical solution, the two drive sprockets are synchronously rotated on the frame via a rotating shaft, and the two ends of the rotating shaft are rotatably mounted on the body of the sugarcane harvester;

[0016] A rotating rod is rotatably mounted on the upper end of the frame. The central axis of the rotating rod is parallel to the central axis of the rotating shaft.

[0027] like Figures 1-3 As shown, this utility model provides a sugarcane harvester's tipping auxiliary device, which is set diagonally below the sugarcane harvester's tipping device 02. It mainly includes a frame 1, a flexible transmission device 2, a lever plate 3, and a limiting plate 11.

[0028] The frame 1 is inclinedly mounted on the body 01 of the sugarcane harvester, providing support and a mounting base for the flexible transmission device 2 and the shift plate 3. The flexible transmission device 2 is mounted on the frame 1 along the inclined direction of the frame 1. Specifically, the flexible transmission device 2 includes two symmetrically arranged drive sprockets 21, two driven sprockets 22, and two chains 23. The two drive sprockets 21 are coaxially rotatable at the bottom of the frame 1. The two driven sprockets 22 are coaxially rotatable at the top of the frame 1, and each chain 23 is driven and sleeved on both the drive sprocket 21 and the driven sprocket 22.

[0029] Two drive sprockets 21 are synchronously mounted on the frame 1 via a rotating shaft 5. Both ends of the rotating shaft 5 are rotatably mounted on the body 01 of the sugarcane harvester via bearing seats. This allows the frame 1, flexible transmission device 2, and lever 3 to rotate freely around the rotating shaft 5 on the body 01 of the sugarcane harvester without affecting the transmission action of the rotating shaft 5 and the flexible transmission device 2. A rotating rod 6 is rotatably mounted on the upper end of the frame 1. The central axis of the rotating rod 6 is parallel to the central axis of the rotating shaft 5. Adjusting frames 7 are fixedly connected to both ends of the rotating rod 6. The adjusting frame 7 includes a connecting part and an adjusting part. The connecting part is fixedly connected to both ends of the rotating rod 6, and one end of the adjusting part is fixedly connected to the middle of the connecting part. The other end has multiple mounting holes 8 arranged along its length for connecting to the body 01 of the sugarcane harvester. By changing the position of the mounting holes 8 connecting the adjusting frame 7 to the body 01, the tilt angle of the frame 1 and the lever 3 can be adjusted to adapt to different sugarcane growth conditions and harvesting needs. Specifically, the tilt of the frame 1 and the lever 3 on it can be adjusted by selecting different mounting holes 8 on the adjustment frame 7 and connecting them to the vehicle body 01.

[0030] A first driven sprocket 9 is fixedly sleeved on one end of the rotating shaft 5. The first driven sprocket 9 is located between the bearing seat and the frame 1. A first driving sprocket 10 is rotatably mounted on the body 01 of the sugarcane harvester. A first chain is driven and sleeved on the first driving sprocket 10 and the first driven sprocket 9. The first driving sprocket 10 can be driven to rotate by the drive structure of other devices of the sugarcane harvester. The first driving sprocket 10 drives the first driven sprocket 9 to rotate through the first chain. The first driven sprocket 9 drives the rotating shaft 5 to rotate, thereby driving the driving sprocket 21 to rotate, causing the chain 23 to rotate.

[0031] Multiple levers 3 are arranged along the transmission direction of chain 23 on the outer surface of chain 23, with each end of a lever 3 fixedly mounted on two chains 23. Each lever 3 has an L-shaped cross-section, with one right-angled side fixedly connected to chain 23 and the other right-angled side used to block and push the bottom of the sugarcane, thus smoothly conveying the bottom of the sugarcane upwards and laying it down, preventing it from slipping and improving the reliability of laying it down. A transition plate 4 is provided between two adjacent levers 3. The transition plate 4 is elongated, with each end fixedly mounted on one of the two chains 23. The transition plate 4 widens the distance between the two levers 3, better accommodating different sugarcane sizes. Additionally, the transition plate 4 also provides support for the bottom of the sugarcane.

[0032] The limiting plate 11 is located above the top of the frame 1, with one side extending axially along the rotating rod 6. This blocking action at the top of the frame 1 helps to prevent the sugarcane from being transported to the top of the frame 1, thus disengaging the bottom of the sugarcane from the guide plate 3. This prevents the sugarcane from continuing to be conveyed downwards with the guide plate 3 and affecting the lowering process, ensuring the sugarcane can smoothly enter the subsequent processing equipment. Specifically, a rod 12 is fixedly installed on one side of the limiting plate 11. Multiple insertion pipes 13 are arranged laterally on the body 01 of the sugarcane harvester, with each insertion pipe 13 corresponding to a specific number of mounting holes 8. The rod 12 is inserted into any of the insertion pipes 13. After adjusting the tilt angle of the frame 1, the position of the limiting plate 11 can be adjusted accordingly, ensuring that the limiting plate 11 is always located at the top of the frame 1. Adjusting the position of the limiting plate 11 can be achieved by inserting the rod 12 into different insertion pipes 13. The design of the insertion rod 12 and the insertion tube 13 not only enables the installation of the limiting plate 11, but also allows the position of the limiting plate 11 to be adjusted according to the actual situation, thus enhancing the adaptability of the device.

[0033] The specific operating steps of this utility model are as follows:

[0034] When using this sugarcane-lowering auxiliary device, firstly, adjust the tilt angle of the frame 1 according to the sugarcane's growth and harvesting requirements. Then, adjust the position of the limiting plate 11 accordingly. Next, start the sugarcane harvester. The first drive sprocket 10 on the vehicle body 01 rotates, driving the first driven sprocket 9 via the first chain. This, in turn, causes the shaft 5 and drive sprocket 21 to rotate. The drive sprocket 21 drives the chain 23, causing the lever 3 and transition plate 4 on the chain 23 to move accordingly. When the sugarcane is positioned at the lowering device 02, its bottom rests against one of the lever 3 or transition plate 4. As the anti-tipping device lowers the sugarcane, the L-shaped lever 3 moves diagonally upwards, pushing the bottom of the sugarcane gradually upwards, thus assisting in the smooth lowering of the sugarcane. When the sugarcane rises to the top of the frame 1 with the lever, the limiting plate 11 blocks the sugarcane, allowing it to detach smoothly from the lever and continue to be lowered by the lowering device for subsequent processing.
