Description

Automatic seed feeding and discharging sugarcane planter

Technical Field

The utility model relates to the field of agricultural machinery, in particular to an automatic seed feeding and discharging sugarcane planter for pre-cutting type multi-bud sugarcane planting.

Background

In the process of sugarcane production, sugarcane planting is one of the most labor-intensive and important links, and in addition, the quality of planting operation can directly influence the sugarcane yield. Mechanized planting has been substantially popularized in sugarcane planting in many countries in the world, and at present, sugarcane planters mainly have three forms, namely a pre-cutting type, a whole stalk type and a real-time cutting type. The pre-cutting type sugarcane combined planter is frequently used in foreign countries such as America, Australia, Brazil and other developed countries with sucrose industries, sugarcane seed sections used by the planter in the form can be obtained by harvesting a segmenting type sugarcane harvester, can also be manually pre-cut into sugarcane seed sections, are not required to be manually fed in the operation process, are high in mechanization degree and efficiency, have relatively extensive foreign planting agriculture, are low in price, and generally adopt the agriculture planted in large seeding quantity to ensure that the planting process basically has no problems of seeding missing and uneven seeding.

The method is different from sugar producing countries such as the United states, Australia, Brazil and the like which realize whole-course mechanization and use large seeding quantity for planting, the mechanical planting requirement of China is the same as or similar to the planting agriculture of manual seed arrangement as much as possible, the seeding quantity requirement is similar, and the arrangement requirement of the planted sugarcane seeds is similar. The seeding rate of the unit area of the manual seed arrangement is only 1/5 or less of that of foreign machine seeds, and when the seeding rate is too small, the problems of missed seeding or too large seeding rate and the like easily occur when the foreign sugarcane planter or the sugarcane planter designed according to the principle is directly used. For example, 2CZQ1 section type sugarcane planters developed by Guangxi agricultural machinery research institute and willow Z908 precutting type sugarcane planters developed by willow agricultural machinery all use the same scraper type seed feeding and discharging device abroad, and the structure has the disadvantages of too large seed sowing amount, easy miss sowing and poor sowing uniformity.

Therefore, most of sugarcane planting in China also adopts a mode of combining mechanical ditching with manual seed arrangement, and a small part of planting machines used for mechanical planting are basically semi-automatic planting machines for cutting seeds in real time, namely the sugarcane planting machines which adopt whole-stem sugarcane seeds and put the sugarcane seeds into the machines by manpower while cutting the seeds and applying the seeds. The sugarcane planted by the planting machine accords with the sugarcane planting agriculture of China, but has obvious defects: the sugarcane seed carrying capacity is small, a large number of workers are needed during operation, the labor intensity is high, the problem of uneven seeding such as missing seeding and the like is caused due to uneven feeding caused by fatigue of the workers, and the problem that the sugarcane seed planting machine does not really solve the mechanical planting problem of the sugarcane is determined.

In conclusion, the highly automatic sugarcane planting machine suitable for China has higher and stricter design requirements. This is also an important reason why highly automated sugarcane planters with practical utility have not been mature in the market since the national development of sugarcane industry has been mechanized throughout the year. The research and development of sugarcane planting machinery which accords with the sugarcane planting agriculture of China, has no seeding omission, uniform seeding and automatic seed feeding and discharging and effectively reduces manpower is a necessary choice for reducing the production cost of the sugarcane and improving the international competitiveness of the sugar industry of China.
