Description

A bionic wide width leveling seed bed type ditch opener

technical field

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

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 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 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 resolved.

Contents of the invention

The object of the present invention is to provide a wide-width leveling seedbed opener capable of overcoming the above defects and simultaneously realizing wide-width equal-depth and uniform sowing of wheat.

The technical scheme adopted by the present invention to solve the technical problem is: a bionic wide-width leveling seed bed opener, including a seed delivery pipe, a cloth seed box, a seed bed preparation curved surface, and a sword-shaped front edge. Its characteristics are: it can be used in no-tillage seeder and wide seed belt seeder and other operations such as rotary tillage, anti-blocking, ditching, etc.; The curved surface of the gill-shaped seed bed, the front of the cloth seed box and the curved surface of the seed bed are inlaid with a sword-style front edge, and the long jaws like a swordfish spear play the role of splitting the water to separate the soil to both sides. The front cutting edge and the curved surface of the seed bed form a swordfish head shape, which can reduce the forward resistance. The bottom of the seed distribution box is a seed distribution board, and ejection protrusions are set on the seed distribution board. When working, first use the bionic swordfish head-shaped front point and rear width, upper wide and lower narrow seed bed preparation device designed on the front sword-shaped front edge of the ditch opener and the bottom seed bed preparation surface to clean the ground surface, especially the rotary tillage. The uneven bottom of the ditch cut out by the knife is leveled to form a wide U-shaped ditch cross-section plane, and the seeds discharged from the seed meter are transported to the seed delivery pipe through the seed delivery pipe, and then fall into the seed distribution box. The ejection protrusions of the seed distribution board on the bottom surface are evenly distributed to the surrounding after being scattered, and then after repeated ejection, they fall onto the flat seed bed prepared by the sword-shaped front edge and the seed bed preparation curved surface, realizing the accurate contour Sowing ensures the quality of sowing and lays the foundation for increasing crop yield.

The effective benefits of the present invention are: the swordfish gill-shaped seed bed preparation curved surface formed by the sword-type front edge designed in the shape of the bionic swordfish and the bottom of the ditch opener, which is wide at the front and wide at the top and narrow at the bottom, can effectively rotate the tillage The bottom of the ditch opened by the knife should be leveled, because it is a swordfish head shape, which can reduce the forward resistance and avoid the blockage of straw and soil, especially the sword-shaped blade at the front, which can cut weeds and straw, etc. Prevent winding and clogging; the bottom wing adopts a flat section, triangular structure, and reasonable design. It can squeeze the soil on both sides of the ditch and open a wide U-shaped ditch with a flat bottom surface, which can ensure that the seeds fall on the same height plane. Seed bed; when the rotary tiller is used for supporting operations, a part of the soil thrown up by the rotary tiller has fallen back to the surface under the front and lower part of the opener. When the seed bed is prepared, a part of the loose soil is located The bottom and sides of the surface, so the soil is loose below where the seeds fall, on both sides of the wide furrow, plus the soil on the cover behind is also loose, which creates a good seedbed for seed germination and root growth , a good seed bed solves the problems of seed germination and root growth, ensures the consistency of sowing depth, and greatly improves the quality of sowing; in addition, the front blade 1 has a sharp blade, which can handle the poorly treated front rotary tiller The stubble is broken.

specific implementation plan

The seed delivery tube (l) and the seed distribution box (2) can be arranged at an angle of 5°~85°, that is, the seed distribution box (2) and the ground can be arranged at an angle of 5~65°, so that the seed distribution box (2) can distribute seeds smoothly .

The sword-shaped front edge (4) is inlaid and welded to the cloth seed box (2) and the surface of the seed bed (3) to form an integrated swordfish head shape, which strengthens the strength on the one hand and facilitates replacement on the other hand.

The surface of the seed bed preparation is based on " ” represented by a family of fifth-order curves formed by smooth connections.

The bottom surface of the seed bed preparation curved surface (3) is flush with the horizontal plane to ensure the effect of leveling the seed bed.

The middle part of the seed distribution plate (5) is designed with seed ejection protrusions, and the shape of the protrusions can be triangular, square, rhombus, circular, etc. to increase the uniform effect of seed distribution.

In the operation of the equipment supported by the rotary tiller, the seed distribution box (2) is not buried in the soil, but rolled onto the soil that has been dug out by the rotary tiller and partially thrown up, and the seed bed is prepared, and the shape of the seed bed is As shown in Figure 4, the seeds are laid according to the agronomic requirements, and then the seeds are covered by the soil that falls later, and the soil surface is scraped flat by the cover device behind, and then the ground surface is compacted by the pressing wheel. Seeds are surrounded by loose soil, creating a loose bed for seed germination and root system, thus improving seeding quality.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be Modifications or equivalent replacements of the technical solutions without departing from the spirit and scope of the technical solutions of the present invention shall be covered by the scope of the claims of the present invention.
