Bionic wide-width leveling seed bed type opener

Abstract

The invention relates to a bionic wide-width leveling seed bed type opener and belongs to the technical field of agricultural machinery. The bionic wide-width leveling seed bed type opener comprises a seed conveying pipe, a seed distribution box, a seed bed preparation curve surface, a sword type front cutting edge and the like, and can be used for working conditions of rotary tillage type tillage, blocking prevention, ditching and the like of a no-tillage seeder, a wide-seed band seeder and the like; the seed conveying pipe and the seed distribution box are welded so as to form a whole body; a swordfish gill type seed bed preparation curve surface is arranged below the seed distribution box; the sword type front cutting edge is embedded in front of the seed distribution box and the seed bed preparation curve surface to divide soil from the two sides; a seed distribution plate is arranged on the bottom face of the seed distribution box and an ejection bulge is arranged above the seed distribution plate, so as to be beneficial to uniform seed distribution; the equal-depth accurate seeding is realized; the seeding quality is guaranteed; a foundation is laid for the yield improvement of crops.

Description

technical field [0001] The patent of the present invention relates to a wide-width leveling seedbed type ditch opener used in protective cultivation land and wheat wide-width operation in the Huang-Huai-Hai area, and belongs to the technical field of agricultural machinery. Background technique [0002] Conservation tillage has developed rapidly in our country. In conservation tillage technology, no-tillage seeding technology is the key. One of the key links in the promotion and implementation of conservation tillage system is the no-tillage planter with perfect performance and reliable quality. The key to wide-width wheat planting is also the wheat wide-width planter. Compared with ordinary seeders, no-tillage seeders and wide-width wheat seeders have special requirements for ditch openers, which are the soil working parts that form seed beds and affect seeding quality, in addition to better anti-blocking performance. At present, the seed belt rotary tillage seeder is the ...

AI Technical Summary

Problems solved by technology

At present, the seed belt rotary tillage seeder is the most widely used, and the wide-width seeding is also mostly used with the seed belt rotary tillage. The ditch openers are basically seed delivery heads, which have no ditching effect and rely on the ditch opened by the rotary tiller. For seeding, the rotary tiller itself has the disadvantage of uneven bottom of the rotary tillage, and the seed is sown in a seed belt wider than the operating width of a single rotary tiller, which causes extremely uneven sowing depth and a large difference in depth, which seriously affects the sowing operation The quality of the seedlings causes a large difference in the emergence time. According to investigations, the difference in sowing depth is 1-7cm, and some are 10cm. The difference in emergence time is generally 1-5 days. The extreme phenomenon that the seedlings cannot even emerge has become a bottleneck problem affecting the promotion of these two sowing methods. In addition, there are also problems such as uneven distribution of sowing. These problems directly affect the final yield and urgently need to be solved
