Description

Technical Field

[0001] The utility model relates to the technical field of sugarcane harvesters, in particular to a compact and lightweight transmission device for sugarcane harvesters. Background Art

[0002] Sugarcane, a crop grown in temperate and tropical zones, is the raw material for producing sucrose and can be used to extract ethanol as an energy alternative. Rich in sugar and water, sugarcane also contains various vitamins, fats, proteins, organic acids, calcium, iron, and other substances beneficial to human metabolism. It is primarily used for sugar production. With the widespread promotion and adoption of agricultural mechanization, the use of specialized sugarcane harvesters has become a common practice in sugarcane cultivation.

[0003] The patent name is: A conveying structure of a sugarcane harvester (patent application number: 202123110258.1). The patent discloses a conveying structure of a sugarcane harvester, including a frame, an oblong through-hole, a conveying roller, a vertical reciprocating drive and a diversion assembly; the frame is composed of two first vertical plates and a second vertical plate arranged vertically in a mirror state; the oblong through-hole is arranged from left to right through the first vertical plate and the second vertical plate; the conveying roller is rotatably arranged between the first vertical plate and the second vertical plate; the vertical reciprocating drive is slidably arranged between the first vertical plate and the second vertical plate; the diversion assembly is fixedly installed at the output end of the vertical reciprocating drive. The conveying roller of this application adopts an assembled design, which realizes the silt filtering work of the sugarcane during transportation without affecting the normal transmission of the sugarcane, while reducing its own material usage, and can automatically adjust the auxiliary paving height of the stacked sugarcane according to different quantities of sugarcane to avoid squeezing between the sugarcanes or causing blockage of the conveying roller.

[0004] In the above case, during the process of transporting sugarcane, multiple conveyor rollers are driven to rotate by belt transmission to achieve the purpose of transporting the sugarcane. However, after long-term use, the belt will become loose, which may easily cause the conveyor rollers to slip or become unable to rotate, thereby reducing the efficiency of sugarcane transportation. When the belt needs to be disassembled and replaced, the staff needs to pry it with tools, which is time-consuming and labor-intensive. Therefore, it is necessary to propose a compact and lightweight sugarcane harvester transmission device to solve the above problems. Utility Model Content
