A device for scraping and preparing soil for furrows after sowing of wheat for equal depth sowing

Abstract

The invention relates to a wheat after-sowing furrow soil scraping and finishing machine for equal-depth sowing and belongs to the technical field of agricultural machinery. The Wheat after-sowing furrow soil scraping and finishing machine for equal-depth sowing r mainly comprises soil scraping and finishing curved surface scrapers, a fixing adjusting plate, a connecting plate, plane scrapers and the like, and can be used for furrow soil scraping and finishing operation after furrowing, sowing and soil covering of no-tillage and wide-seed-belt sowers and the like. The scraping and finishing machine comprises the scraping and finishing curved surface scrapers and the plane scrapers, adopts a double-sword scraper structure with bilaterally symmetrical layout, and has flat bottom surface and dovetail-shaped tail part, a channel is reserved in the middle to prevent blockage, and a stop bolt can be used for vertical height adjustment to meet different agricultural requirements. Aiming at the non-uniform soil covering after sowing of a sower during work, the scraping and finishing machine generates pressure and pushing force on soil to move the soil, a large quantity of soil is pushed to two sides, a small quantity of soil moves to the middle, the soil is scraped flat, meanwhile, ridging is performed on two sides of the soil under the action of two wings of each curved surface scraper, the surface is smooth, uniform soil covering and equal-depth sowing are guaranteed, and the sowing quality is improved.

Description

technical field [0001] The patent of the invention relates to a ridge and furrow scraping soil preparation device for equal depth sowing used in protected cultivation land and wheat wide sowing operations 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. The key to wide-width sowing of wheat is that the seedbed is flat, the sowing depth is consistent, and the thickness of the covering soil is required to be consistent. At present, the seed belt rotary tillage seeder is the most widely used, and most of the wide-width sowing is also used....

AI Technical Summary

Problems solved by technology

At present, the seed belt rotary tillage seeder is the most widely used, and most of the wide-width sowing is also used. The non-directionality and randomness of falling cause the extreme unevenness of the covering soil. The quality of the covering soil has an important impact on the emergence of seeds and the yield of crops. Seeds with thick soil cover are slow to emerge, and shallow-sowed seeds with thin soil cover are fast to emerge, but shallow-sowed seeds are easy to be washed by rain and direct sunlight, and it is difficult to germinate, which directly affects the emergence of seedlings.

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. It has become a bottleneck problem affecting the promotion of these two seeding methods, which urgently needs to be solved
