Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a sugarcane leaf shredder. Background Art

[0002] Sugarcane is my country's primary sugar crop, accounting for over 85% of the country's annual sugar crop area and producing over 90% of its total sugar output. The sugarcane industry has become a key pillar of economic development in major sugar-producing regions and a major source of income for farmers. Sugarcane production generally follows a one-year new planting system and a two-year perennial planting system. Because perennials typically experience a significant decline in yield after two or three years, requiring replanting, sugarcane production is a highly investment-intensive, labor-intensive, and labor-intensive industry compared to other field crops. Sugarcane perennial stubble trimming involves using a stubble trimmer to promptly trim any excess sugarcane tips after harvest to prevent tip breakage and bud loss, promote bud germination, and increase seedling emergence rates, thereby extending the life of perennial sugarcane.

[0003] The announcement number is CN221598597U, and the patent name is a perennial sugarcane stubble cutter and side bottom tillage stubble cutter, which discloses a frame, wherein the front part of the frame is provided with a side cantilever seat and a middle cantilever seat for being installed and connected to a tractor; side bottom tillage ploughshares are respectively installed on both sides of the front end of the frame through downwardly extending plow bars, and a gear transmission box is installed on the frame, and a power input shaft that can be connected to the power shaft of the tractor is installed at the front end of the gear transmission box, and the power input shaft is connected to the input gear in the gear transmission box, and two power output shafts are provided at the bottom of the gear transmission box, and the power output shafts are correspondingly connected to the left knife drive shaft and the right knife drive shaft, etc. The technical characteristics of the perennial sugarcane stubble cutter and the side bottom tillage stubble cutter are that they use two groups of six curved axe-type blades connected in pairs to form a three-petal curved knife to cooperate in cutting and stubble cutting, which can smoothly cut the perennial sugarcane heads and avoid the perennial sugarcane heads from cracking or being cut continuously;

[0050] Working principle of the present invention:

[0051] The present invention provides a sugarcane leaf shredder and trimmer. During operation, the operator surveys the field conditions in advance to check for large rocks and obstructions. If any are present, they are removed. The operator then uses a tractor to move the sugarcane leaf shredder and trimmer to the operating position. After lowering the machine to the ground, the power system is activated. The leaf shredder gearbox 21 is driven by an external power device (in conventional methods, a tractor is generally used to drive the sugarcane leaf shredder and trimmer, and the external power is provided by the tractor). The transmission mechanism 3 then drives the leaf shredder assembly 22 to rotate. The rotating column 2231 in the leaf shredder 223 also rotates, and the leaf shredder section begins to shred leaves.

[0052] The leaf shredding gearbox 21 rotates while driving the stubble gearbox 41 to rotate. The stubble gearbox 41 drives the gearbox 42 and the stubble assembly 43 to rotate. Finally, the stubble assembly 43 is used to cut and stubble the perennial sugarcane heads.

[0053] After the operation is completed, the field is inspected to find out the gaps and fill them in, to prevent the impact of inadequate operation due to land or machinery problems on the root sugarcane's tillering, and then the ridges are broken and fertilized in time.

[0054] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention.
