Bounce-proof ditching device for wide and equal-height seeding

Abstract

The invention relates to a bounce-proof ditching device for wide and equal-height seeding, and belongs to the technical field of agricultural machinery. The ditching device comprises a tail wing, a bump, a scraper, a seeding box, a seed tube, a front cutting edge, a seed scattering plate, a seedbed, and the like. The ditching device is characterized in that: the device can be used for situations of no-tillage and wide seeding work; the tail wing, the bump, the scraper, the seeding box and the seed tube are welded to form an integral body; a seedbed leveling device composed by the tail wing, the bump and the scraper is arranged below the seeding box; the front part of the device is inlaid with the sliding knife type front cutting edge, so that the forward resistance is reduced, and grass entanglement is prevented; the seed scattering plate is arranged inside, so that seeds are scattered along the wide seedbed; the bump is arranged on the lower side, and scratches flanges are formed on the seedbed, so that seed bounce is reduced, and fixed-point and uniform seeding of seeds is facilitated. According to the device, equal-height and accurate seeding is achieved, the seeding quality is guaranteed, and the foundation for improving crop yield is laid.

Description

technical field [0001] 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 [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 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, Covere...

AI Technical Summary

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 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, the width of the ditch is too narrow to meet the agronomic requirements, etc., and it has not been applied. Once the above problems are solved, it will be widely used
