Problems solved by technology

Compared with ordinary seeders, no-tillage seeders and wheat wide-width seeders require better anti-blocking performance, but also for the formation of seed beds, the uniformity of seed distribution, and the soil working parts that affect the quality of sowing - ditch openers, There are also special requirements, especially the wheat wide sowing technology has strict requirements on the uniform distribution of wheat seeds within the sowing bandwidth. Although the structure of the existing single seed tube opener is relatively simple, it is affected by manufacturing, adjustment and operating environment conditions. , it is difficult to achieve uniform distribution of seeds on both sides, but the existing double-pipe openers have too much space in the cross-section, which is easy to cause weeds and congestion; in addition, chemical fertilizers are required to be applied while sowing, and the Separate sowing, the spacing should be between 40-60mm, different from the base fertilizer, when sowing, the seed fertilizer is applied, the amount of fertilizer is not large, but it should be as accurate as possible, that is, the position of the fertilizer should generally be below or on the side of the seed 40-60mm
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.

Embodiment Construction

[0014] The whole opener is laid out around the fertilizer delivery pipe 1, and it is connected with the double seed delivery pipe 2 (welded together through the connecting plate), the seed distribution box 4, the narrow fertilizer ditch shovel wing 5, the wide seed belt shovel wing 3 and the transition The shovel wings 7 etc. are welded into one, the front lower part is inlaid with the sword type front cutting edge 6, the narrow fat ditch shovel wings 5, the wide seed belt shovel wings 3 and the excessive shovel wings 7 are welded on both sides, the double seed delivery pipe 2 is connected with the cloth The seed box 4 is welded together, and the fertilizer delivery pipe 1 is used as the shovel handle of the ditch opener, which plays the role of connecting and supporting the ditch opener and the frame, and bears various forces that the ditch opener is subjected to. Design elongated narrow rectangle to coincide with narrow fat ditch shovel wing 5, to reduce fat ditch width.

Abstract

The invention relates to a bionic narrow-fertilizer ditch and wide-seed band double-seed path opener and belongs to the technical field of agricultural machinery. The bionic narrow-fertilizer ditch and wide-seed band double-seed path opener comprises a fertilizer conveying pipe, a double-seed-path seed conveying pipe, a seed distribution box, a narrow-fertilizer ditch shovel wing, a wide-seed band shovel wing, a transition shovel wing, a sword type front cutting edge, a scattering plate, a seed baffling plate and the like; the bionic narrow-fertilizer ditch and wide-seed band double-seed path 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; seed fertilizer application, equal-depth accurate seeding and uniform distribution of seeds in the seed band are realized; the seeding quality and the fertilization quality are guaranteed; a foundation is laid on the yield improvement of crops; the head-on space of the opener is greatly increased and the problems of grass hanging and congestion are solved.

Description

technical field [0001] The patent of the invention relates to a bionic compact narrow fertilization ditch wide seed belt double seed track 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] Wheat wide-drilling is a new cultivation technique, which has significant yield-increasing benefits and has been highly valued by the state. Conservation tillage technology has developed rapidly in our country. One of its key technologies is no-tillage seeding technology. One of the key links in the promotion and implementation of conservation tillage system is no-tillage seeder with perfect performance and reliable quality; wheat wide The key to wide-width planting is also the wheat wide-width planter. Compared with ordinary seeders, no-tillage seeders and wheat wide-width seeders require better anti-blocking performance, but also for the format...
