Description

Technical Field

[0001] The utility model relates to a sugarcane cutter for a sugarcane stacker. Background Art

[0002] Currently, there are three types of sugarcane mechanized harvesting methods in China. The first is segmented harvesting, which is also the most mature method internationally. The second is whole-stalk harvesting, which aims to achieve the same effect as manual harvesting, but no fully developed model has yet been developed. The third is a step-by-step harvesting method. First, a harvester and buncher cuts the sugarcane roots and collects them into bins. The harvest is then unloaded and transferred to defoliation equipment for removal of tops or segmented harvesting before being shipped to the sugar factory.

[0003] The third option involves harvesters and stackers. Some manufacturers lack a top-cutter function, or their top-cutter rate is low. Adding a top-cutter during operation reduces the complexity of the subsequent work and significantly reduces labor intensity. Furthermore, the typical structure is a combination of a top-cutter disc and a top-pulling disc. The top-cutter is complex, heavy, and located high, which can easily cause an unstable center of gravity when crossing ridges or climbing slopes, leading to tipping of the harvester. Furthermore, the top-pulling disc in this configuration can significantly entangle grass. Utility Model Content

[0004] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a sugarcane buncher cutter.

[0005] A sugarcane buncher cutter includes a frame with a disc-shaped cutter disc on the frame, a plurality of blades spaced apart on the outer arc surface of the cutter disc, guide rods on both sides of the cutter disc, the guide rods being mounted on the frame, the spacing between the first ends of the two guide rods being smaller than the spacing between the second ends, the cutter disc being located near the first end, and fixed blades on both sides of the cutter disc being provided on the guide rods, with the tips of the fixed blades facing the inside of the guide rods.

[0006] Preferably, a connecting column is provided at the center of the upper end surface of the cutter disc, a chamber is provided in the connecting column, a hydraulic motor for driving the cutter disc is provided in the chamber, the connecting column is fixed in the mounting seat, and the mounting seat is fixedly connected to the frame.

[0007] Preferably, a plurality of ribs are provided on the upper surface of the cutter disc, and the ribs are circumferentially spaced along the outer arc surface of the connecting column. The bottom surface of the ribs is fixedly connected to the cutter disc, and the side surface is fixedly connected to the outer arc surface of the connecting column.

[0008] Preferably, the frame is connected to the rear conveying frame through at least two connecting rods, one end of the connecting rod is hinged to the frame, and the other end of the connecting rod is hinged to the rear conveying frame, the middle section of one of the connecting rods is hinged to the floating joint of the cylinder, the floating joint is installed in the base of the cylinder, and the base of the cylinder is hinged to the rear conveying frame.

[0009] Preferably, the blade is triangular in shape.

[0010] Beneficial effects: Compared with the prior art, the utility model simplifies the conventional three hydraulic motors into one hydraulic motor and two fixed blades. The overall structure is lighter and the cutting effect is the same. The improved cutting device has a self-cleaning function, and the cut tips are thrown out through the ribs, which is not easy to get entangled in grass. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0016] like Figure 1-3 As shown, the frame 1, the mounting base 2, the connecting column 3, the rib 4, the cutter head 5, the blade 6, the fixed blade 7, the guide rod 8, the connecting rod 9, the rear conveying frame 10, and the oil cylinder 11;

[0017] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a sugarcane buncher cutter.

[0018] A sugarcane buncher cutter includes a frame 1, a disc-shaped cutter disc 5 is mounted on the frame 1, a plurality of blades 6 are spaced apart on the outer arc surface of the cutter disc 5, guide rods 8 are provided on both sides of the cutter disc 5, the guide rods 8 are mounted on the frame 1, the spacing between the first ends of the two guide rods 8 is smaller than the spacing between the second ends, the cutter disc 5 is located near the first end, and the guide rods 8 are provided with fixed blades 7 on both sides of the cutter disc 5, with the tips of the fixed blades 7 facing the inside of the guide rods 8.

[0019] In this embodiment, a connecting column 3 is provided at the center of the upper end surface of the cutter disc 5, a chamber is provided in the connecting column 3, a hydraulic motor for driving the cutter disc 5 is provided in the chamber, the connecting column 3 is fixed in the mounting seat 2, and the mounting seat 2 is fixedly connected to the frame 1.

[0020] In this embodiment, a plurality of ribs 4 are provided on the upper surface of the cutter disc 5. The ribs 4 are circumferentially spaced along the outer arc surface of the connecting column 3. The bottom surface of the ribs 4 is fixedly connected to the cutter disc 5, and the side surface is fixedly connected to the outer arc surface of the connecting column 3.
