A kind of high-level and wide-width sowing ditch opener for deep fertilization of wheat

Abstract

The invention relates to a high-position and wide-width sowing ditch opener for deep fertilization of wheat, which belongs to the technical field of agricultural machinery, and includes a front knife edge, a fertilization pipe, a seed delivery pipe, a seed distribution box, a seed bed preparation device, etc., and is used for no-tillage It can complete the high-position sowing operation with the wide seed belt seeder. The front edge of the knife is welded together with the fertilization pipe, the soil moves to both sides during the operation, and the seed ditch is opened for deep fertilization; the three-way seed pipe is separated in the middle to realize independent wide-width sowing on both sides; seed boxes and seed beds The finisher moves forward closely with the fertilization pipe, and a symmetrically arranged M-shaped seed bed finisher is arranged under the seed distribution box, which is in the form of sharp corners, and the seed scattering plate on the bottom is provided with ejection protrusions. When working, the M-type seed bed preparation device at the bottom of both sides of the seed distribution box will level the uneven bottom of the ditch to form a wide dustpan-shaped ditch section plane, and at the same time, the seeds will fall from the three-way seed delivery pipe to the cloth. The seed box falls evenly onto the flat seed bed through repeated ejection by the scattering plate, so as to achieve uniform seeding at equal heights.

Description

technical field [0001] The patent of the invention relates to a high-position and wide-width sowing ditch opener for deep fertilization of wheat used in conservation tillage and wide-width operation of wheat in the Huanghuaihai region, which 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 conservation tillage technology is the same, and the key to wheat wide planting is also wheat wide planter. Compared with ordinary seeders, no-tillage seeders and wide-width wheat seeders have special requirements for openers, which form the seedbed and affect the quality of the soil, in addition to better anti-blocking performance. . At present, the se...

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 generally ranges from 1 to 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 problems such as uneven sowing distribution, which directly affect the final yield of crops, and urgently need to be solved
