Rice Seedling Transplanter Adjustable Spacing Design And Experimental Research

Mechanization sterile seedling transplanting technology is a rice bowl dish seedlings at the core of the new mechanized cultivation techniques, can be ordered simulate artificial planting seedlings, achieve roots with soil planting, seedling and root injury injury rate, fast turning green seedlings, the climate has compensation.At present, most areas used is the introduction of Japan, South Korea or counterfeit Japan, South Korea fixed line spacing seedling transplanter, and a great south, north of differences in weather conditions, resulting in different rice cultivation systems north and south, so use these fixed leading the seedling transplanter planting rice in all regions of China is very scientific. On the one hand because of different varieties of rice in the appropriate spacing to achieve maximum yield, seedling transplanter existing fixed line spacing is too large lead to planting density less than normal, not full yield potential of seedling transplanting; On the other hand it can not adjust the line spacing be exotic jobs based on rice cultivation requirements, it is not conducive to the mechanization of rice planting in large scale applications. To solve these problems, this paper mainly from the following aspects of the spacing adjustable seedling transplanter research:1) Existing fixed line spacing seedling transplanter proposed based spacing adjustable seedling transplanter machine design scheme, according to the program carried out in various parts of the transplanter draw two-dimensional drawings and machining, and assembly of the case in accordance with the debugging process some issues to improve the existing structure.2) In seedling transplanter double crank rod transplanting mechanism for the study, Solidworks for transplanting mechanism using three-dimensional modeling, ADAMS software and use its motion simulation research institutions, transplanting mechanism verify the reasonableness of the trajectory.3) Transplanter comparative tests on prototype testing and field performance of different transplanting, assess whether the design of the prototype performance indicators and verification and yield potential advantages planting seedling transplanter.By studying the above aspects, the following conclusions:1) Transplanter for seedling transplanting mechanism for three-dimensional modeling and simulation analysis the structure obtained reasonable, Trajectories meet and planting seedlings take the job requirements.2)Performance testing showed that the prototype: seedling transplanter performance testing prototypes and design requirements in line with agriculture, the detection of indicators are better than the standard value, good quality planting prototype.3) Transplanting comparison test showed different: seedling transplanting technology than blanket transplanting seedlings planting quality is better, transplanting seedling planting seedling roots with soil, root, root injury hurt small seedlings; no rejuvenation period after transplanting, rice does not affect the growth period, does not affect the rice planting; rice seed rate, panicle length and more grains, grain full, production increased by 26.9% over the actual production transplanting seedlings blanket, play a greater yield advantage of seedling transplanting, worth in large scale.
