Novel intelligent regulating isobathic seeding device for wide seedling zone

Abstract

The invention relates to a novel intelligent regulating isobathic seeding device for a wide seedling zone and belongs to the technical field of agricultural machinery. The device comprises a press wheel device, an adjusting bolt 1, an adjusting bolt 2, a post-seedling furrowing and scraping hostling device, a connecting plate, a deep fertilizing isobathic wide-width seeding opener, an intelligent regulating system, a parallel four-rod mechanism and the like and can be used for no-tillage seeding and wide-width seeding of crops such as wheat, rice and the like, so that the problems that the seeding depths of no-tillage seeding and wide-width seeding are inconsistent and the emergence time difference is great and the like are solved. The deep fertilizing isobathic wide-width seeding opener is used for leveling a rotary tillage groove to form a flat seed bed; the post-seedling furrowing and scraping hostling device scraps soil and uniformly earths, so that the seed earthing depths are consistent; the intelligent regulating system senses surface relief according to signal change of a pressure sensor, controls retraction of an electric push rod, and moves up and down with the parallel four-rod mechanism connected with the isobathic seeding system to realize quick and accurate profiling with ground so as to achieve a purpose of intelligently regulating the seeding depth.

Description

technical field [0001] The patent of the present invention relates to a new type of wide seedling belt intelligent control contour sowing device used in no-tillage and wide-width sowing operations of various crops such as wheat and rice, and belongs to the technical field of agricultural machinery. Background technique [0002] With the acceleration of national agricultural mechanization and modernization, no-tillage and wide-width sowing machinery have been further developed. The no-tillage and wide-width sowing technology system will also be the main mechanized sowing technology for agricultural development in the future. To achieve rapid promotion of these technologies For application, it is necessary to improve the level of mechanization and intelligence of this technology and the level of refined operation of key technical links, and a good intelligent control system is one of the key components of intelligent machinery. From the perspective of the world's agricultural ...

AI Technical Summary

Problems solved by technology

However, my country has not yet paid attention to this aspect, especially in wheat sowing. For example, wheat no-tillage and wide-width sowing are compared with ordinary sowing machines. In addition to requiring perfect sowing mechanical properties, reliable quality, and anti-blocking performance, In addition to uniform sowing and prevention of missed seeds, there are strict requirements on the sowing depth of wheat at 3-5cm, ditching, uniform soil covering, and consistent sowing depth

The current no-tillage seeder and wide-width seeder have poor profiling effect of the seeding system, insufficient accuracy of ground movement, long lag time, and lack of equal depth adjustment devices, which make the difference between seeding and covering soil depth large and difficult. Satisfying the requirement of consistent sowing depth seriously affects the quality of sowing operation, and the emergence time varies greatly, resulting in weak seedlings, poor growth and development, and affecting wheat yield

According to investigations, the difference in sowing depth is 1 to 7 cm, and some 10 cm. The difference in emergence time is generally 1 to 5 days. It directly affects the normal growth and development of crops and directly affects the final yield. It has become a key problem affecting the effect of current mechanized sowing, which seriously hinders the research and promotion of no-tillage sowing machinery, and urgently needs to be solved.
