[0002] Because the sugarcane growing areas of Guangxi and Yunnan are primarily hilly, with 70% of the plots small and scattered, existing segmented and whole-stem combine harvesters fall short of the harvest quality expectations of sugarcane producers and farmers. Promoting a step-by-step mechanized harvesting model characterized by "high-efficiency harvesting, low loss rate, and efficient weed removal" is a more suitable and readily accepted mechanical harvesting method for the geographical conditions of Guangxi and Yunnan, and a new, effective mechanized harvesting method for sugarcane harvesting in hilly areas, creating an urgent market demand.

[0003] Existing sugarcane combine harvesters and sugarcane reapers use a cutting blade to cut the tops. This is not effective when harvesting sugarcane of varying heights, affecting subsequent leaf stripping and weed removal. Harvesting of fallen sugarcane is also inefficient or impossible, impacting cutting quality.

[0016] Figure 1 This is a schematic structural diagram of the tail leaf shredder mechanism of the sugarcane cutter and paver according to the present invention; DETAILED DESCRIPTION

[0017] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0018] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0019] like Figure 1As shown, a sugarcane cutter and paver tail leaf shredder mechanism according to a specific embodiment of the present invention comprises a shredder frame 1, a lifting mechanism 2, and a shredder mechanism 3. The shredder frame 1 is mounted on the cutter and paver frame. Vertical guide rails are provided on both sides of the shredder frame 1. The lifting mechanism 2 is mounted on the shredder frame 1. Two lifting mechanisms 2 are provided, one on each side of the shredder frame 1, ensuring smoother operation. The shredder mechanism 3 comprises a shredder roller 31 and a drive element. The shredder roller 31 is positioned transversely to the front end of the lifting mechanism 2. Multiple shredder ropes 32 are arranged on the outer surface of the shredder roller 31 in three rows, axially attached to the outer surface of the stripping roller 31. The drive element is connected to the shredder roller 31 to drive the roller 31 to rotate, and the shredder ropes 32 strike the sugarcane tips, removing them. The shredder roller is preferably an electric shredder roller, and the shredder ropes are nylon ropes.

[0020] During sugarcane tip removal, the driving element drives the leaf shredder roller 31, which rotates at a high speed of approximately 1000 rpm. The shredder rope, under the action of centrifugal force, strikes the delicate sugarcane tips, breaking up the leaves at the tips. The shredder rope strikes the sugarcane tips with a large amplitude, equal to the rotational diameter of the rope at both ends.

[0021] Preferably, the driving member is a chain transmission assembly 33 and a power member 34, and the power member is a motor. The chain transmission assembly is connected to the leaf crushing roller, and the power member is connected to the chain transmission assembly to drive the leaf crushing roller to rotate.

[0022] Preferably, the lifting mechanism 2 is constructed as follows: each lifting mechanism 2 includes a primary telescopic lifting rod 21, a secondary lifting chain 22, a sprocket (not shown), and a lifting frame 23. The sprocket is located at the upper end of the leaf shredder frame 1. The primary telescopic lifting rod 21 is a pneumatic or oil cylinder telescopic rod. In this embodiment, it is an oil cylinder, which is mounted on the leaf shredder frame 1. The primary telescopic lifting rod 21 is connected to one end of the secondary lifting chain 22. The secondary telescopic lifting rod 21 passes through the sprocket, with one end connected to the primary telescopic lifting rod 21 and the other end connected to the lifting frame 23. The lifting frame 23 is mounted on the guide rails of the leaf shredder frame 1 and can be moved up and down. The leaf shredder mechanism 3 is mounted on the lifting frame 23 and is used to remove sugarcane tips.

[0023] The lifting mechanism of this new sugarcane tip shredder utilizes a first-stage telescopic lifting rod and a second-stage lifting chain. The first-stage telescopic lifting rod allows adjustment of the second-stage lifting chain, which in turn adjusts the height of the mounting frame. The shredder is mounted on the lifting frame and can be adjusted in height by extending and retracting the hydraulic cylinder, which drives the second-stage lifting chain. This two-stage lifting system allows for flexible shredding heights ranging from 1.5 meters to 3.8 meters. During operation, the operator adjusts the shredder's height to suit the height of the sugarcane tip using the lifting mechanism. The shredder removes the sugarcane tips.

[0024] Preferably, a pair of supporting rods 4 are provided on the lifting frame 23, and the pair of supporting rods 4 are located at the front end of the leaf crushing mechanism 3 and are arranged opposite to each other in an 8-shaped manner. The supporting rods 4 guide the tail of the sugarcane into the leaf crushing mechanism to facilitate the operation of the tail mechanism.
