Efficient automatic rice tray seedling raising precise sowing production line

Abstract

The invention discloses an efficient automatic rice tray seedling raising precise sowing production line. The production line is composed of a steel wire chain feeding mechanism, a subsoil laying device, a subsoil compacting device, an intelligent double filling type hole drum sowing device, a topsoil laying device, an electric control box, a power motor, a soil collecting bucket, a seed receivingtank, a tray embedding device, an automatic tray stacking device and a rack. Accordingly, synchronous positioning and transportation on soft plastic pot body seedling trays, subsoil laying and compaction, precise sowing, topsoil covering, hard tray embedding and automatic stacking can be performed at a time; by means of the subsoil compaction device, the tray subsoil is compacted, the amount of subsoil is increased, and the later period seedling planting and inserting are facilitated; on the basis of the detection and control technology, an intelligent precise sowing device comprising a seedfilling performance detection system is researched and developed, and 1-3 grain/hole sowing of hybrid rice is achieved; by arranging the tray embedding and automatic tray stacking devices, the automation degree of the production line is improved, the functions are complete, and by means of the soft plastic pot body seedling tray operation, the current rice light simplified cultivation operation requirements are met.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a high-efficiency automatic precision seeding production line for rice plug seedling raising. Background technique [0002] Hybrid rice occupies a very important position in my country's rice production. From 1976 to 2013, China's hybrid rice planting area accumulated nearly 400 million ha 2 , has made a great contribution to ensuring my country's food security. However, in recent years, with the transformation and development of rice production methods in China, the planting area of ​​hybrid rice has shown a downward trend. According to the latest data, the planting area of ​​hybrid rice in my country in 2013 was 16.1787 million hm 2 , accounting for 53.37% of the country's rice planting area, which is 14.6 percentage points lower than the historical high in 1995. One of the important reasons is that the mechanized planting technology suitable for hybrid rice pro...

Problems solved by technology

[0007] In recent years, Song Jiannong of China Agricultural University, Li Yaoming of Jiangsu University, and Zhang Ruilin of Nanjing Institute of Agricultural Mechanization have further studied the pneumatic seed metering device, and mainly use the air suction type, which has the advantages of high operating speed and low seed damage rate. Realize precision sowing such as single-grain on-demand sowing, but because rice mainly uses bud seeds to sow and raise seedlings, the seed buds fall off and easily block the suction holes and affect the sowing performance, and the problem of suction hole blockage has not been well solved, so this principle has not been well developed Applications

Yu Yaxin et al. established the lateral vibration dynamics model of the vibrating plate of the rice metering device, and carried out vibration analysis by using a vibration test collector, etc., and studied the lateral vibration characteristics of the vibrating plate of the vibrating seed metering device, which improved the orderly sowing accuracy of hybrid rice. , but the sorting efficiency is low and has not been used in practice
