Description
Technical Field
The invention relates to the technical field of sesame weeding and topdressing machines, in particular to a self-propelled farmland weeding and topdressing all-in-one machine based on image processing.
Background
Sesame is used as a traditional crop in China, is an important characteristic oil crop in China, has an area of 700 ten thousand mu throughout the year, and is mainly planted in regions with double cropping in one year, such as Huang-Huai region and Jiang-Huai region. The sesame seeds are generally sown in wide and narrow rows, the seedling stage is from the emergence of seedlings to the bud stage, the sesame seeds grow slowly, the height of the seedlings is less than 20 centimeters, row weeds of the sesame seeds grow extremely fast, the normal growth of the sesame seeds in the seedling stage is influenced, and the later-stage yield is greatly reduced. Weeding is mainly carried out in a mode of hoeing by manpower or spraying pesticides at present; the manual hoeing effect is very slow, the labor intensity is very high, the seedlings are very easy to be injured by spraying pesticides, and in addition, negative influences are caused on the environment, the soil and the growth of sesame seedlings. However, no sesame special intertillage weeding machine exists in the current market, only part of small herbicides are mainly prepared by modifying production machines of crops such as cotton, sunflower and the like, the small herbicides are not matched with agricultural technologies of sesame agricultural machines, and the small intertillage weeding machine is easy to be entangled and blocked in operation and has lower weeding efficiency. The reformed small sesame intertillage weeder has the following defects: the small sesame intertillage weeder can only be provided with a single dedusting reamer, weeds in a wide row cannot be completely removed, and sesame seedlings are fragile and more weeds can exist around the sesame seedlings, namely the weeds in a narrow row of sesame cannot be weeded; most of weeding reamer on the weeder is fixed mounting on the machine, can not carry out artificial regulation according to the height of sesame to the height of weeding reamer, cause the phenomenon of weeding effect not good even hindering the seedling.
Therefore, the current sesame planting is mainly performed manually, the labor cost of production links such as weeding and harvesting accounts for about 60% of the whole production cost, the sesame planting cost in China is as high as 500 yuan/mu, and the American sesame planting cost with low labor cost and high mechanization degree is only 100-200 yuan/mu. The production mode with high cost and low benefit causes a plurality of farmers to abandon sesame production, thus leading the comprehensive productivity and competitiveness of the sesame in China to be stricken greatly.
In recent years, along with the improvement of living standard of people, the health care function of sesame (especially the black sesame) is more and more emphasized by people, so that the demand of the sesame is increased year by year, the productivity and the competitiveness of sesame raw materials are directly related to the stability and the durability of sesame product supply in China, but the domestic sesame production can not meet the market demand far away.
In view of the fact that sesame is used as a special health-care agricultural product, the structure adjustment of the planting industry of China is increased, the planting area of the sesame is gradually recovered, but the industrial development is still restricted due to the low mechanization degree and the high production cost of the sesame. Therefore, in sesame planting, the lack of key technologies and equipment for efficient intertillage weeding is a bottleneck problem to be solved urgently at present.
