Description

Anti-bounce ditching device for wide and contoured cloth

technical field

The patent of the invention relates to a wide-width contour seed anti-bounce ditching device used in no-tillage and wide-width sowing operations of various crops such as wheat and rice, 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 no-tillage seeder and direct seeding machine with perfect performance and reliable quality. Etc., the same as the conservation tillage technology, the key to wheat wide planting is also wheat wide planter. Compared with ordinary seeders, no-tillage seeders, rice direct seeders and wheat wide-width seeders require better anti-blocking performance, and the soil working parts that form seed beds and affect the quality of sowing, such as ditch openers, Coverers, packers, etc. also have special requirements, especially the most stringent requirements for openers. 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 operation, which has good anti-blocking performance, but has high manufacturing costs, high power consumption, harsh working environment, and complicated operations. , large difference in sowing depth, and poor operation quality; although the disc opener has low manufacturing cost and good adaptability, it is especially suitable for no-tillage, with many straws and stubbles, but because of its W shape , The bottom of the ditch is uneven, the depth of sowing is not easy to control, the depth is different, and the width of the ditch is too narrow to meet the agronomic requirements, but it has not been applied. Once the above problems are solved, it will be widely used. In foreign countries, the equal depth profiling device is installed on the disc opener to achieve equal depth sowing in corn sowing, and good results have been achieved.

Contents of the invention

The object of the present invention is to provide an anti-bounce ditching device for wide and contoured cloth that can overcome the above defects and realize wide and contoured cloth at the same time.

The technical solution adopted by the present invention to solve the technical problem is: a kind of anti-bounce ditching device for wide-width and contour seed distribution, including tail fins, bumps, scraper boards, seed distribution boxes, seed delivery pipes, front cutting edges, loose Seed boards, seed beds, etc., are characterized by: they can be used for no-tillage and wide-width sowing operations; The seed bed leveling device consists of bumps and soil scrapers. The front of the seed box is inlaid with a sliding knife-shaped front edge, which can reduce the forward resistance and prevent grass from being entangled. The wide seed bed is spread out, and the raised blocks are set under the seed distribution box to draw convex ribs on the seed bed to reduce the bouncing of seeds, which is conducive to the fixed-point and uniform distribution of seeds, and realizes the precise distribution of contours. It has laid the foundation for ensuring the quality of sowing and improving crop yield.

The advantages of the anti-bounce ditching device for wide and contoured seed distribution with the above structural characteristics are as follows: 1. The seed bed leveling device is composed of tail fins, bumps and scraper boards under the seed distribution box to scrape the seed bed. The whole is a wide U-shaped ditch, and the width of the seed box is 60-300mm; 2. The front of the seed box is inlaid with a sliding knife-shaped front edge, which can reduce the forward resistance and prevent grass from being entangled. The curve formula of the sliding knife blade is: y =-0.0218x ³ -0.0311x ² -1.9564x+84.577; 3. A seed spreading board is installed inside the seed distribution box to let the seeds spread along the wide seed bed, and the spreading width is 20-300mm; 4. Set under the seed distribution box The shape of the bump is an irregular triangular pyramid, and the convex edge is drawn on the seed bed. The pyramid can reduce the bouncing of the seed, which is conducive to the uniform distribution of the seed at a fixed point. The size of the bump is 0-100mm long, and the bottom The bottom width is 0-30mm, and the height is 0-30mm; and it has good adaptability to the field to ensure the quality of work.
