Equal-depth and wide seeding opener for deep fertilization of wheat

Abstract

The invention relates to an equal-depth and wide seed opener for deep fertilization of wheat and belongs to the technical field of agricultural machinery. The opener comprises a front cutting edge, a fertilization pipe, a seed conveying pipe, a seed distributing box, and seedbed reconditioning machines for equal-depth seeding operation by a no-tillage and wide zone seeder. The front cutting edge and the fertilization pipe are integrally welded and soil in the operating process moves toward two sides to form a seed channel for the deep fertilization; the three-way seed conveying pipe is separated in the middle, so that the independent wide seeding at two sides is achieved; the seed distributing box and the seedbed reconditioning machines follow the fertilization pipe to move forward, the M type seed bed reconditioning machines are symmetrically arranged below the seed distributing box in forms of sharp corners, and a seed scattering plate on the bottom surface is provided with an ejecting bump. During work, the M type seed bed reconditioning machines on the bottoms of tow sides of the seed distributing box level the bottom of a trench with the uneven surface so as to form a wide dustpan-shaped plane with a trench cross section, and meanwhile, seeds fall into the seed distributing box by virtue of the three-way seed conveying pipe and are repeatedly ejected and uniformly scattered to a level seedbed by virtue of the seed scattering plate, so that the equal-depth uniform seeding is achieved.

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...

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
