A Bionic Compact Narrow Fertilizer Ditch Wide Seed Belt Ditch Opener

Abstract

The invention relates to a bionic compact type narrow-fertilizer ditch and wide-seed band opener and belongs to the technical field of agricultural machinery. The bionic compact type narrow-fertilizer ditch and wide-seed band opener comprises a fertilizer conveying pipe, a seed conveying pipe, a seed distribution box, a narrow-fertilizer ditch shovel wing, wide-seed band shovel wings, a transition shovel wing, a sword type front cutting edge, a scattering plate, a seed baffling plate and the like; the bionic compact type narrow-fertilizer ditch and wide-seed band opener 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, and can also be applicable to the working condition of directly breaking stubbles and ditching on a cultivated land or an uncultivated land by a common no-tillage seeder. The fertilizer conveying pipe and the seed conveying pipe are welded by virtue of a connection plate so as to form a whole body; the seed conveying pipe and the seed distribution box are welded to form a whole body; the sword type front cutting edge is embedded at the front lower end of the fertilizer conveying pipe; the wide-seed band shovel wings are arranged on the two sides of the seed distribution body; the sword type front cutting edge is internally embedded in front of the fertilizer conveying pipe, the fertilizer ditch shovel wing, the wide-seed band shovel wings and the transition shovel wing; the scattering plate and the seed baffling plate are arranged on the bottom face of the seed distribution box. The equal-depth accurate seeding is realized and a seed fertilizer is applied; the seeding quality and the fertilization quality are guaranteed; the foundation is laid on the yield improvement of crops.

Description

technical field [0001] The patent of the present invention relates to a bionic compact narrow fertilizer ditch wide seed belt ditch opener used in protected cultivation land and wheat wide operation 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 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 the same time of sowing, chemical fe...

Problems solved by technology

One of the most widely used types at present is the rotary tillage (actually belt tillage, the same below) plowing seeder, and most of the wide sowing uses rotary tillage with seed belts. Generally, there are two ditch openers, and the fertilization ditch opener in front , the ditch is very deep and wide. Due to the ditching and soil covering effect of the rotary tiller, the fertilizer ditch can basically be buried flat (except when the soil moisture is too wet and the water content is too high). Considering the blockage of the back soil The problem is that the distance between the two is far away, but the ordinary seeder directly ditches and sows on cultivated or uncultivated land. Because the depth of the ditch is deep, if the soil is moist, it is difficult to cover the ditch, which will bring more problems for the subsequent sowing operations. Difficult, easy to cause inconsistency in guaranteed depth; behind the fertilization ditch opener of belt tillage seeder is the sowing ditch opener, the ditch opener is basically a seed delivery head, without ditching function, it relies on the ditch opened by the rotary tiller for sowing , the rotary tiller itself has the disadvantage that the bottom of the rotary tillage is uneven, 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 gap between depth and depth, which seriously affects the quality of sowing operations , resulting in a large difference in 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 of not being able to produce seedlings has become a bottleneck problem affecting the promotion of these two sowing methods; To cover the seeds, the bottom of the ditch - the seed bed is greatly affected by the shape of the bottom of the ditch opener. In addition, agronomy requires the application of fertilizer at the same time as sowing to avoid fertilizer damage to the seeds. Traditional ditch openers use fertilization ditch openers and sowing ditch The structure is relatively complicated, and the longitudinal size is large, resulting in a very uncompact structure of the planter and poor operability. In addition, the fertilization opener is relatively wide, and the fertilizer ditch opened is very wide. The flatness of ditching has a great influence on the outstanding problems. At the same time, there are also uneven sowing distribution and root stubble treatment of previous crops. These problems directly affect the final yield and urgently need to be solved.
