Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, and particularly relates to a self-propelled sugarcane field cutting, impurity removing and transporting machine. Background Art

[0002] There are two common existing sugarcane harvesting methods: 1. Manual whole-stalk harvesting, which accounts for about 90%. Advantages: low impurity content in sugarcane, strong flexibility, not affected by plot and weather. Disadvantages: low efficiency and high harvesting cost. 2. Combine harvesting, which accounts for about 10%. Advantages: relatively high efficiency and relatively low harvesting cost. Disadvantages: greatly affected by plot size, sugarcane planting pattern, lodging situation, weather, etc., and there are two major problems of large field harvesting losses (about 8% - 10% loss, mainly due to the loss of cut sugar water and comminution loss caused by poor harvesting of lodged sugarcane) and high impurity content (the impurity deduction rate in sugar mills is generally 8 - 15%, mainly sugarcane stumps and sediment), and the comprehensive loss rate is greater than 15%.

[0003] The comprehensive loss of sugarcane combine harvesting is often higher than the cost of sugarcane manual harvesting, which is the fundamental reason why sugarcane combine harvesting has been difficult to promote. However, with the aging of the population, the reduction of the working-age population, and the increase in labor prices, the proportion of sugarcane manual harvesting has been decreasing year by year, and it is an irreversible trend for machine harvesting to replace manual harvesting. In order to solve the problems of large losses and high impurity content in current sugarcane combine harvesting, the Guangxi sugarcane area has proposed a step-by-step sugarcane harvesting mode: separating the three major steps of sugarcane cutting, transporting, and impurity removing, mainly separating the sugarcane cutting process where sugarcane losses are likely to occur, and using a cutter-lifter to cut and lay sugarcane or manually cut sugarcane according to the lodging situation of sugarcane, with almost no cutting loss and basically eliminating sugarcane stumps and sediment.

[0004] The current step-by-step sugarcane harvesting mode promoted by several mainstream manufacturers in the market is whole-stalk cutting and laying (or manual cutting), machine loading, short-distance transportation, and centralized cutting and impurity removing. Centralized cutting and impurity removing requires a workshop of at least 4 mu, requires a power supply of more than 50 KVA, requires a proper amount of small transfer vehicles to transport sugarcane with leaves from the field to the site for centralized impurity removing treatment, and the sugarcane leaves piled up in the workshop need to be cleaned in time. The sugarcane cutting process basically eliminates sugarcane stumps, and the impurity removing effect is better than that of the traditional field integrated cutting and impurity removing combine harvester. However, it has the problem of secondary cleaning of sugarcane leaves, and increases the input of site, machines, and labor, resulting in high sugarcane harvesting costs.

[0005] The information disclosed in this background art section is only for enhancing the overall understanding of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.
